Overview

Package types defines data structures and types used throughout the system These types are shared across different service modules to ensure data consistency

Package types defines the core data structures and interfaces used throughout the WeKnora system.

Package types defines data structures and types used throughout the system

Package types — shared secret redaction helpers.

VectorStore connection configs and tenant KV configs (web search, parser engine, storage engine) use the redacted-placeholder round-trip pattern:

  • GET responses replace set secrets with RedactedSecretPlaceholder (or empty string when unset).
  • PUT requests treat "", or RedactedSecretPlaceholder as "preserve existing"; any other value replaces the stored secret.

MCP / Model / WebSearch provider / DataSource credentials use a dedicated /credentials subresource instead; see internal/handler/dto/mcp.go.

Package types: sandbox backend config entity.

A workspace holds several named sandbox configs so different agents can run on different backends (e.g. a big-memory E2B account for data analysis, a self-hosted Cube for everything else). The credential-bearing payload lives in Config, reusing TenantSandboxConfig's encrypted Value/Scan hooks.

Constants

View Source 
const (
	ImageDetailBrief = "brief"
	ImageDetailFull  = "full"
)

Image description detail levels requested by a file read.

View Source 
const (
	AgentGrantScopeSession    = "session"
	AgentGrantScopeAutomation = "automation"
)

Agent grant scopes. A session grant lives as long as its root conversation; an automation grant lives with its automation and stops applying when the automation's binding changes.

View Source 
const (
	AgentGrantLapseRevoked = "revoked"
	AgentGrantLapseExpired = "expired"
	// AgentGrantLapseChanged: the run's configuration differs from the one
	// the grant was given under.
	AgentGrantLapseChanged = "changed"
	// AgentGrantLapseIdle: an automation grant went unused too long.
	AgentGrantLapseIdle = "idle"
)

Why a remembered grant no longer applies. The approval card shows it so the user knows why they are asked again.

const (
	AgentPromptKindToolApproval = "tool_approval"
	AgentPromptKindMCPOAuth     = "mcp_oauth"
	AgentPromptKindAskUser      = "ask_user"
)

Kinds of human-in-the-loop prompts an agent run can raise.

View Source 
const (
	// AgentPromptPending: an owner replica is blocked waiting in memory.
	AgentPromptPending = "pending"
	// AgentPromptSuspended: the run ended; an answer will resume it.
	AgentPromptSuspended = "suspended"
	// AgentPromptAnswered: the user responded; Response holds the answer.
	AgentPromptAnswered = "answered"
	// AgentPromptExecuting: the answer authorized a side effect that is
	// running; it must not be replayed if the executor disappears.
	AgentPromptExecuting = "executing"
	AgentPromptDone      = "done"
	AgentPromptFailed    = "failed"
	AgentPromptCanceled  = "canceled"
	AgentPromptExpired   = "expired"
	// AgentPromptSuperseded: the user moved on (new message, rewind,
	// deletion) while the prompt was suspended.
	AgentPromptSuperseded = "superseded"
)

Lifecycle states of an AgentPrompt. Transitions are compare-and-set on the row, so every replica agrees on a single outcome.

Span kinds — kept narrow because every kind has dedicated rendering on the frontend timeline:

  • SpanKindRoot — the per-(knowledge, attempt) trace root. Always the parent_span_id ancestor of every other span in that attempt. UI uses it for total elapsed.
  • SpanKindStage — one of the 5 canonical stages (DocReader, etc.). UI renders these as the timeline segments.
  • SpanKindSubSpan — anything inside a stage (e.g. multimodal.image[i]). UI shows them as collapsible children.
  • SpanKindGeneration — a SubSpan that wraps an LLM/VLM call. Same UI treatment as SubSpan but tagged so we can stitch to the matching Langfuse generation.

	SpanStatusSkipped   = "skipped"   // intentionally not run (e.g. multimodal on a text-only doc)
	SpanStatusCancelled = "cancelled" // not run because an upstream span failed
)

Span statuses. We deliberately distinguish "failed" (this span itself errored) from "cancelled" (an upstream span failed and we abandoned this one without running it) so the UI can render the cause differently — "you broke X, so we never ran Y" vs. "Y itself broke".

Stage names — the closed set the UI builds its 5-segment timeline from. Adding a stage requires a coordinated frontend release. SubSpan names are free-form (e.g. "multimodal.image[0]") and don't go through this list.

const (
	PreprocessModeOff    = "off"
	PreprocessModeAuto   = "auto"
	PreprocessModeAlways = "always"
)

The modes the preprocessing action's own switch accepts, and what each means: 

auto   the describe round also observes the page's geometry
       (layout.margin / layout.upright) and the page is straightened
       and cropped only when those say it is worth it;
off    (default) never preprocess, and leave the describe prompt exactly as it was
       before this feature existed;
always preprocess every readable page without asking, and likewise leave
       the describe prompt untouched.

Only auto changes the describe prompt; off and always cannot disturb an observation pipeline that is already tuned. The switch is declared by the preprocessing action (types.ImageActionPreprocess) and stored in the slot of the pipeline that offers it, like every other pipeline setting.

A mode is a SETTING — what the knowledge base asked for. What actually happened to an image is a different question with a different vocabulary, and it is recorded on the trace as preprocess.result.

It is attrs/2 since an unobserved attribute stopped being written as a conservative default: an absent key now means "the observation did not answer for this attribute" and is read through the pipeline's ocr_on_unobserved setting, so a consumer of stored observations must not assume every registered key is present. Bump it when an attribute's semantics change, not when one is merely added.

const MaxInlineDocumentImages = 30

MaxInlineDocumentImages is the number of Markdown data-URI images the parser stores in one pass. Producers must use a file export when a document exceeds this budget, rather than leave unprocessed base64 in searchable content.

MaxMemoryTombstones bounds how many rejections one subject accumulates. Beyond it the oldest are dropped: a rejection from long ago matters less than the store growing without limit.

View Source 
const MaxPageContextIssues = 20

MaxPageContextIssues bounds how many Wiki issues one page context names.

View Source 
const MaxRequestedResults = 200

MaxRequestedResults caps the result counts a retrieval API caller may ask for (knowledge-search match_count, rerank.top_k). knowledge-search runs one search per scoped document or tag set and reranks every candidate, so an unbounded count multiplied into tens of thousands of billed rerank passages.

const MessageRunStateAwaitingInput = "awaiting_input"

MessageRunStateAwaitingInput marks an assistant message whose run ended suspended on an agent prompt and will resume once the user answers.

View Source 
const MinSandboxWriteCompletionTokens = 8192

MinSandboxWriteCompletionTokens is the floor applied to an explicitly configured per-round budget when a sandbox is bound. write_sandbox_file and edit_sandbox_file carry the whole file body inside the tool-call JSON, so a cap sized for ordinary chat truncates the arguments mid-string on every attempt — the agent then burns its rounds rewriting a file it can never finish. Below this the setting is not a preference, it is a deadlock.

const ModelDisplayNameMaxLen = 255

ModelDisplayNameMaxLen matches models.display_name VARCHAR(255).

View Source 
const ModelIDMaxLen = 64

ModelIDMaxLen is the upper bound on `models.id`. Matches the actual schema width on both PostgreSQL (varchar(64) in migrations/versioned/ 000000_init.up.sql) and SQLite (varchar(64) in migrations/sqlite/ 000000_init.up.sql). Loaders that accept user-provided ids (e.g. the built-in models YAML loader) must reject anything longer to avoid a "value too long for type" failure at INSERT time.

View Source 
const ModelUsageListLimit = 50

ModelUsageListLimit caps how many knowledge bases or agents are listed in a model-in-use error. Totals are returned separately so the cap cannot under-count the references that actually block deletion.

const PipelineToolCallIDPrefix = "ragpipe-"

PipelineToolCallIDPrefix marks a persisted tool call the model never made. The fast-answer (KnowledgeQA) pipeline records its retrieval stages as tool calls so a reloaded conversation can redraw the same timeline it showed while streaming. History replay must skip them: asking the model to account for calls it never issued, against tools it may not even have, breaks the request protocol.

RedactedSecretPlaceholder is the fixed value returned in API responses whenever a sensitive field is set but withheld from the client.

const SandboxConfigIDGlobalDefault = "-"

SandboxConfigIDGlobalDefault is retained for sessions created by older versions that used a deployment-wide sandbox configuration.

A sentinel rather than the empty string, so NULL on sessions.sandbox_config_id unambiguously means "this session has no live sandbox".

View Source 
const SandboxCordonLease = 2 * time.Minute

SandboxCordonLease bounds how long a cordon is honoured. Identity changes take the cordon for the duration of two provider API calls; anything older is a crashed handler's leftover and must not wedge the config.

const SessionOwnerAPIExternalUserPrefix = PrincipalAPIExternalUser + ":"

SessionOwnerAPIExternalUserPrefix prefixes sessions.user_id for rows created by a tenant API key whose request resolved an external-user identity. The remainder is "<tenantID>:<externalUserID>".

View Source 
const SessionOwnerAPITenantKeyPrefix = "api_tenant_key:"

SessionOwnerAPITenantKeyPrefix prefixes sessions.user_id for rows created by a tenant API key. The full owner id is "api_tenant_key:<tenantID>:<keyID>", so a LIKE '<prefix>%' selects every API-key session in the tenant.

View Source 
const SessionSourceAPI = "api"

SessionSourceAPI is the source filter that lists every session created via a tenant API key across the whole tenant. It is an admin-only view: the service layer requires Admin+ and drops the per-user owner scope so a tenant Owner/admin can observe API-key traffic that is otherwise isolated per key.

View Source 
const SessionSourceWeb = "web"

SessionSourceWeb is the source filter for a user's own Web-console chats.

const SkillMaintenanceSessionMarker = "skill_maintenance:"

SkillMaintenanceSessionMarker tags the sessions that skill image operations run in. Those sessions carry a real agent transcript that is deliberately kept for troubleshooting, but they are infrastructure rather than conversations, so the console must never list them. This mirrors how embed sessions are classified (EmbedSessionMarkerPrefix): a description prefix, so no schema change is needed.

SourcedAnswerOutputPrompt is a conditional output policy included in the stable system prefix. Discovering an image must not fabricate another user request.

const StreamEndedEarlyError = "the model's response ended before it finished (connection interrupted)"

StreamEndedEarlyError is what a consumer reports for an answer that arrived with FinishReasonIncomplete: the stream stopped before the provider said the message was finished, most often because a proxy cut the connection.

const WikiCategoryMaxDepth = 3

WikiCategoryMaxDepth is the hard cap on how many folder levels a wiki page's category_path may keep. The ingest prompts intentionally ask the model for at most 2 levels to keep the directory tree shallow; this storage cap is one level deeper as a defensive bound so a slightly over-eager model (or a reconcile remap) cannot create an unbounded breadcrumb. It is the single source of truth shared by the service, repository, and taxonomy layers so stored paths and queried paths are always cleaned identically.

WikiFolderRootID is the sentinel parent/folder id meaning "the wiki root" (a page or folder directly under the top level, with no parent folder).

SharedImageActions are the actions every pipeline starts from. They are declared here and bound to handlers by the registry; an action that belongs to a single pipeline instead registers under a "<pipeline_id>.<action>" id.

	StagePostProcess: {StageEmbedding, StageMultimodal},

StageDependencies declares the DAG between stages. Used by the tracker to cascade-cancel dependents when a stage fails — a Chunking failure silently turns Embedding/Multimodal/PostProcess into "cancelled" so the timeline shows a clear blast radius instead of three pending spinners.

Important: Multimodal does NOT depend on Embedding. They share Chunking as their upstream and are otherwise independent (Multimodal kicks off regardless of vector indexing config). PostProcess joins both before running its handlers.

var ValidateModelParameters func(modelName string, modelType ModelType, params *ModelParameters) error

validateBuiltinModelEntry returns nil if the entry is loadable, or an error describing what's wrong. Catches the failure modes that would either crash the INSERT or silently produce an unusable row:

  • empty id (cannot UPSERT)
  • id longer than the DB column (PG/SQLite cap at varchar(64), see ModelIDMaxLen) which would fail at INSERT time
  • empty or misspelled type (provider factories match exact strings)
  • explicit non-empty status outside the known set

Source is intentionally NOT validated against a fixed list because the provider matrix in internal/models/* keeps growing and a too-strict check here would force changes in two places per new provider. ValidateModelParameters is set at startup to runtime.ValidateRow. It is a hook rather than a direct call because internal/models/catalog imports this package, so the dependency can only run in this direction. A nil hook (unit tests, tools that never build the container) simply skips the check.

Functions

func ActingViaFromContext added in v0.9.0 

func ActingViaFromContext(ctx context.Context) string

ActingViaFromContext returns what acts for the caller in ctx, or "" when the caller acts in person.

func ActionParam added in v0.9.0 

func ActionParam(id ImageActionID, name string) string

ActionParam namespaces one of an action's own tunables: the caption action declares a "thinking" switch and the key it is stored and traced under is "caption.thinking".

The full naming rules — three families, the ownership test, the value vocabularies, and where to change keys when you rename one — live in docs/design/image-pipeline-naming.md. This comment keeps only what a caller needs at the call site.

Declaring the bare name is the point. Two actions may each want a "thinking", and a pipeline may want one too, without either inventing a distinct spelling for the same idea: an action's params live in the action's namespace, a pipeline's private params live inside the pipeline's own stored map, and the two cannot meet. A key written by hand would need a naming rule remembered by everyone; derived here, it is a rule the compiler and the tests can hold.

func AgentMaxContextTokens 

func AgentMaxContextTokens(configured, modelContextWindow int) int

AgentMaxContextTokens picks the context window for one agent run. An explicit agent setting wins, then whatever the model declares, then the assumed default.

func AgentRoundMaxCompletionTokens 

func AgentRoundMaxCompletionTokens(configured int) int

AgentRoundMaxCompletionTokens returns the completion-token budget for one ReAct LLM round when no sandbox is bound. Zero (unset) uses DefaultSmartReasoningMaxCompletionTokens. An explicit configured value is honored as-is.

func AgentRoundMaxCompletionTokensFor 

func AgentRoundMaxCompletionTokensFor(configured int, sandboxConfigID string) int

AgentRoundMaxCompletionTokensFor is AgentRoundMaxCompletionTokens with the agent's sandbox: unset + sandbox uses the large write-file budget, and a configured value too small to hold a file write is raised to the floor.

func AppendCustomPromptInstructions 

func AppendCustomPromptInstructions(prompt, instructions, label string) string

AppendCustomPromptInstructions appends user-authored business guidance to a system-owned prompt. Stable output, safety and citation rules always win.

func ApplyAgentMemoryPreference 

func ApplyAgentMemoryPreference(ctx context.Context, enabled *bool) context.Context

ApplyAgentMemoryPreference threads an agent's memory switch into ctx. A nil preference inherits the workspace setting.

func ApplyBuiltinAgentLocalization 

func ApplyBuiltinAgentLocalization(ctx context.Context, agent *CustomAgent)

ApplyBuiltinAgentLocalization overlays the locale-specific name, description, and avatar from builtin_agents.yaml onto a persisted built-in agent. Tenant-specific Config and other DB fields are left untouched.

Built-in agents are seeded into the database with the locale that was active at first run. ListAgents / GetAgentByID used to return those stored strings verbatim, so switching the UI language left the cards in Chinese (or whichever language was seeded). YAML already has per-locale copy; this applies it on the read path.

func ApplySkipGeneratedQuestions added in v0.9.0 

func ApplySkipGeneratedQuestions(results []*SearchResult, disabled map[string]struct{})

ApplySkipGeneratedQuestions marks rerank passages whose knowledge base has question generation turned off. disabled maps knowledge base IDs.

func AssignChunkSeqIDs 

func AssignChunkSeqIDs(tx *gorm.DB, chunks []*Chunk) error

AssignChunkSeqIDs assigns sequential SeqIDs to a batch of chunks that have SeqID == 0. Must be called before CreateInBatches for SQLite compatibility.

func AttachmentHandle 

func AttachmentHandle(id string) string

AttachmentHandle is the stable, model-facing name of a pre-uploaded attachment. It is derived from the document ID so every turn and every replayed history message name the same file the same way.

func AttachmentPath 

func AttachmentPath(id string) string

AttachmentPath is the read_file address of a pre-uploaded attachment.

func AuthSourceForBoundOwnerID added in v0.9.0 

func AuthSourceForBoundOwnerID(ownerID string) string

AuthSourceForBoundOwnerID describes an owner bound after creation (MCP ask, embed backfill). Those binders only ever bind shared-entry or channel owners, so the result can never qualify a session for a shared machine.

func AuthorizeTenantAPIKeyKnowledgeBases 

func AuthorizeTenantAPIKeyKnowledgeBases(ctx context.Context, kbIDs ...string) error

AuthorizeTenantAPIKeyKnowledgeBases rejects KB-restricted API key callers that target one or more knowledge bases outside their allow-list.

func AuthorizeTenantAPIKeyKnowledgeTargets 

func AuthorizeTenantAPIKeyKnowledgeTargets(ctx context.Context, kbIDs, knowledgeIDs []string) error

AuthorizeTenantAPIKeyKnowledgeTargets rejects KB-restricted API key callers that reference knowledge_ids without a verified KB binding, or kb_ids outside the allow-list.

func AuthorizeTenantAPIKeyOptionalTagIDs 

func AuthorizeTenantAPIKeyOptionalTagIDs(ctx context.Context, tagIDs []string) error

AuthorizeTenantAPIKeyOptionalTagIDs rejects tag_ids for KB-restricted keys because tag resolution can pull documents from arbitrary knowledge bases.

func AutomationActingVia added in v0.9.0 

func AutomationActingVia(id string) string

AutomationActingVia is the Principal.ActingVia of a run of automation id.

func AutomationRunActive added in v0.9.0 

func AutomationRunActive(status string) bool

AutomationRunActive reports whether a run in status still holds the automation: it is executing or waiting for the user.

func AutomationRunFinished added in v0.9.0 

func AutomationRunFinished(status string) bool

AutomationRunFinished reports whether status is final.

func BuildResourcePath 

func BuildResourcePath(handle string) string

BuildResourcePath creates a stable application resource reference.

func BuildStorageBackendPath 

func BuildStorageBackendPath(backendID, providerPath string) string

func CalculateFAQContentHash 

func CalculateFAQContentHash(meta *FAQChunkMetadata) string

CalculateFAQContentHash 计算 FAQ 内容的 hash 值 hash 基于：标准问 + 相似问（排序后）+ 反例（排序后）+ 答案（排序后） 用于快速匹配和去重

func CanonicalizeDenyOut 

func CanonicalizeDenyOut(denyOut []string) []string

CanonicalizeDenyOut rewrites any IPv4 /0 onto DenyAllIPv4 so providers that string-match 0.0.0.0/0 (E2B's ALL_TRAFFIC) see the same deny-all the validator accepted. Other entries are copied as typed. Nil input stays nil.

func ClampMemoryImportance 

func ClampMemoryImportance(importance int) int

ClampMemoryImportance keeps importance inside the 1..5 scale.

func ClarifyArtifactVersions 

func ClarifyArtifactVersions(content string, current, previous MessageArtifacts, language string) string

Do not silently redirect old handles: the user may be comparing versions. When an answer references a previous version of a regenerated output, attach an explicit old/current pair. Preserve all original prose and destinations.

func CleanWikiCategoryPart 

func CleanWikiCategoryPart(part string) []string

CleanWikiCategoryPart normalizes a single raw category label that may itself carry embedded separators, wrapping quotes/brackets, or page-type noise, and returns the cleaned sub-labels (type labels such as "entity"/"实体" dropped).

func CleanWikiCategoryPath 

func CleanWikiCategoryPath(parts []string) []string

CleanWikiCategoryPath cleans, deduplicates, and caps a full category path at WikiCategoryMaxDepth. Centralizing this guarantees that the path a page is stored with and the path a list/filter query is matched against go through the exact same normalization, so directory filters cannot silently drift.

func ContainsStorageReference 

func ContainsStorageReference(text, reference string) bool

ContainsStorageReference matches an exact token in text or nested JSON.

func ContextCloneDecision 

func ContextCloneDecision(key ContextKey) (clone bool, declared bool)

ContextCloneDecision reports whether the key survives a detach, and whether any decision has been recorded for it at all. The second return value is what the coverage test uses to tell a deliberate false from an omission.

func CosineSimilarity 

func CosineSimilarity(a, b []float32) float64

CosineSimilarity scores two vectors in [-1, 1]. Mismatched lengths score 0: vectors from different models are not comparable, and guessing is worse than declining to answer.

func DecodeEmbedding 

func DecodeEmbedding(raw []byte) []float32

DecodeEmbedding unpacks a vector written by EncodeEmbedding.

func DefaultLanguage 

func DefaultLanguage() string

DefaultLanguage returns the configured default language locale. It reads the WEKNORA_LANGUAGE environment variable; if unset, falls back to "zh-CN".

func DefaultMCPEndpointTools 

func DefaultMCPEndpointTools() []string

DefaultMCPEndpointTools is the allowlist a new endpoint starts with: every read-only tool, nothing that writes.

func DefaultMaxCompletionTokens 

func DefaultMaxCompletionTokens(agentMode, sandboxConfigID string) int

DefaultMaxCompletionTokens is the unset-config default for one agent: quick-answer 2048, smart-reasoning 24576 with or without a sandbox.

func DefaultParserEngine 

func DefaultParserEngine(fileType string) string

DefaultParserEngine returns the engine used when no parser_engine_rules match. Empty string means builtin (docreader) or Go simple-format routing. When the anydoc binding is linked it is preferred for every type it converts (except Go simple formats). ppt/pptx otherwise fall back to markitdown.

func DenyOutCoversAllIPv4 

func DenyOutCoversAllIPv4(denyOut []string) bool

DenyOutCoversAllIPv4 reports whether a deny list blocks every IPv4 destination. That is the second of the two ways an admin can express the deny-all fallback — the first being DenyEgressByDefault — and ValidateSandboxNetworkPolicy treats them as equivalent, so every consumer that asks "does this policy deny by default?" has to accept both or it will misjudge a config the admin was allowed to save.

It normalises through classifyNetworkTarget rather than comparing strings so it cannot disagree with the validator about which entries count: any /0 collapses onto 0.0.0.0/0, and surrounding whitespace is ignored. Entries the validator would reject are skipped here; rejecting them is its job.

func DetectExplicitMemory 

func DetectExplicitMemory(query string) (string, bool)

DetectExplicitMemory extracts the statement from a "remember ..." directive. It returns ok=false for anything else, including a bare directive with no statement after it.

func EmbedVisitorIDFromContext 

func EmbedVisitorIDFromContext(ctx context.Context) string

func EncodeEmbedding 

func EncodeEmbedding(vector []float32) []byte

EncodeEmbedding packs a vector as little-endian float32.

func EnvLanguage 

func EnvLanguage() string

EnvLanguage returns the WEKNORA_LANGUAGE environment variable value, or empty string if unset.

func FAQChunkNeedsStatusSync 

func FAQChunkNeedsStatusSync(src, dst *FAQChunkStatus, mappedSrcTagID string) bool

FAQChunkNeedsStatusSync reports whether a matched pair needs status sync.

func FAQChunkStatusFieldsEqual 

func FAQChunkStatusFieldsEqual(a, b *FAQChunkStatus) bool

FAQChunkStatusFieldsEqual compares status fields (tag excluded).

func FilterKnowledgeBasesForTenantAPIKeyScope 

func FilterKnowledgeBasesForTenantAPIKeyScope(
	ctx context.Context, requestedKBIDs, resolvedKBIDs []string,
) ([]string, error)

FilterKnowledgeBasesForTenantAPIKeyScope intersects resolved KB IDs with the API key allow-list. When the caller supplied explicit kb_ids, every ID must be allowed; implicit agent defaults are intersected instead of rejected.

func FormatArtifactModTime 

func FormatArtifactModTime(t time.Time) string

FormatArtifactModTime encodes an mtime for message_artifacts.mod_time.

func FormatEmbeddingLiteral 

func FormatEmbeddingLiteral(vector []float32) string

FormatEmbeddingLiteral renders a vector the way pgvector parses it, so the database can do the distance arithmetic instead of shipping every stored vector to the application to be scored there.

func FormatWikiSourceRef 

func FormatWikiSourceRef(knowledgeID, title string) string

FormatWikiSourceRef builds the stored source_refs entry for a knowledge ID and optional title. A title that contains "|" is kept verbatim: the parser splits on the first pipe only, so the ID half stays unambiguous.

func GalleryAttrID 

func GalleryAttrID(sourceID, name string) string

GalleryAttrID joins a source id and a source-local attribute name into the namespaced id used across the gallery contract and every config tier.

func GalleryAttrSourceIDs 

func GalleryAttrSourceIDs() []string

GalleryAttrSourceIDs lists the registered source ids in priority order.

func GeneratedQuestionRowPredicate added in v0.9.0 

func GeneratedQuestionRowPredicate(alias string) string

GeneratedQuestionRowPredicate is the SQL form of IsGeneratedQuestionSource. alias is the table qualifier without a dot, or empty for an unqualified column. source_type is inlined; chunk ids are ASCII so length and substr agree on PostgreSQL and SQLite.

func GeneratedQuestionSourceID 

func GeneratedQuestionSourceID(chunkID, questionID string) string

GeneratedQuestionSourceID builds the retrieval source identifier for a generated question. PostgreSQL stores source_id as varchar(64), while a chunk UUID plus a question UUID would be 73 bytes. Preserve the historical representation for short IDs and hash only oversized question IDs so existing index rows remain addressable by delete/reindex operations.

func GetBuiltinAgentIDs 

func GetBuiltinAgentIDs() []string

GetBuiltinAgentIDs returns all built-in agent IDs in fixed order

func GetRetrieverEngineMapping 

func GetRetrieverEngineMapping() map[string][]RetrieverEngineParams

GetRetrieverEngineMapping returns the retriever engine mapping This allows other packages to access the driver capabilities

func GrantsOperationCatalog added in v0.9.0 

func GrantsOperationCatalog(agent *CustomAgent) bool

GrantsOperationCatalog reports whether agent may run WeKnora management operations. Only the built-in assistant does; the ID alone is not enough, since it must come from the built-in registry rather than a stored record.

func GrantsProductDocs added in v0.9.0 

func GrantsProductDocs(agent *CustomAgent) bool

GrantsProductDocs reports whether agent may read the WeKnora documentation bundled with the server. The docs are public, so unlike operations this needs no signed-in user; it is still limited to the built-in assistant.

func HasKnowledgeRetrievalScope 

func HasKnowledgeRetrievalScope(
	searchTargets SearchTargets,
	knowledgeBaseIDs []string,
	knowledgeIDs []string,
) bool

HasKnowledgeRetrievalScope reports whether a request has any effective knowledge retrieval scope. SearchTargets are the unified runtime form and must be considered alongside the legacy/raw KB and knowledge ID fields so tag-only mentions are not mistaken for pure chat.

func ImagePipelineParam added in v0.9.0 

func ImagePipelineParam(params map[string]any, pipelineID, key string) (any, bool)

ImagePipelineParam reads one pipeline setting out of a params map. The key is the running pipeline's slot and nothing else: a params map with no such entry means the setting was never stored, and the caller falls back to what the field declares — which is the same answer the panel draws.

func ImageReadPrompt 

func ImageReadPrompt(detail, focus string) string

ImageReadPrompt is shared by attachment reads and generic tool-image fallback.

func InferStorageFromFilePath 

func InferStorageFromFilePath(filePath string) string

InferStorageFromFilePath deduces the storage provider from a file path format. Used as a safety fallback when the KB's configured provider doesn't match the data. Supports provider:// scheme (local://, minio://, cos://, tos://), unified /files/{provider}/... format, and legacy formats.

func InjectedImageAttrNames added in v0.9.0 

func InjectedImageAttrNames(onDemand bool) []string

InjectedImageAttrNames lists the attributes a describe round asks the model for, given whether the steps that consume on-demand attributes are switched on for this run. The prompt builder and the observation action both take the list from here, so "what was asked" and "what was answered" cannot drift apart.

func IsAPISessionOwnerID 

func IsAPISessionOwnerID(ownerID string) bool

IsAPISessionOwnerID reports whether a stored session owner was produced by a tenant API-key request, with or without an external-user identity.

func IsAppPath added in v0.9.0 

func IsAppPath(path string) bool

IsAppPath reports whether path is a bounded path inside the app, never a URL or a protocol-relative one.

func IsBackgroundTask 

func IsBackgroundTask(ctx context.Context) bool

IsBackgroundTask reports whether ctx was marked as a background worker task (see WithBackgroundTask). Returns false for interactive / HTTP request paths.

func IsBuiltinAgentID 

func IsBuiltinAgentID(id string) bool

IsEnvStoreID checks if the given ID is an env store virtual ID.

func IsGeneratedQuestionSource added in v0.9.0 

func IsGeneratedQuestionSource(chunkID, sourceID string, sourceType SourceType) bool

IsGeneratedQuestionSource reports whether an index row is a generated question for its parent chunk. Rows are written as source_id = chunk_id + "-" + question id (or the hashed "-q" form) with source_type chunk. The chunk body itself uses source_id = chunk_id. Identification does not use the length of source_id.

func IsImageChildChunkType 

func IsImageChildChunkType(t ChunkType) bool

IsImageChildChunkType reports whether a chunk is one the multimodal pipeline hangs under the text chunk that shows an image.

func IsMCPOAuthNonInteractive 

func IsMCPOAuthNonInteractive(ctx context.Context) bool

IsMCPOAuthNonInteractive reports whether ctx was marked non-interactive for MCP OAuth (see WithMCPOAuthNonInteractive), or belongs to an agent run whose mode is not attended.

func IsMostlyRedacted 

func IsMostlyRedacted(content string) bool

IsMostlyRedacted reports whether a statement lost so much that keeping it would store a placeholder rather than a memory.

func IsPageContextPage added in v0.9.0 

func IsPageContextPage(page string) bool

IsPageContextPage reports whether page is a known page identifier.

func IsPageContextSection added in v0.9.0 

func IsPageContextSection(section string) bool

IsPageContextSection reports whether section looks like a UI section key such as "tools" or "knowledge": lowercase words joined by '_' or '-'.

func IsPipelineToolCallID 

func IsPipelineToolCallID(id string) bool

IsPipelineToolCallID reports whether a tool call was synthesized by the fast-answer pipeline rather than requested by the model.

func IsRedactedOrEmpty 

func IsRedactedOrEmpty(s string) bool

IsRedactedOrEmpty reports whether s should be treated as "no change requested" in an Update request.

func IsResidentMemoryKind 

func IsResidentMemoryKind(kind string) bool

IsResidentMemoryKind reports whether items of this kind belong in the always-injected block rather than in query-matched recall.

func IsSandboxWorkspacePolicyRow 

func IsSandboxWorkspacePolicyRow(e *TenantSandboxConfigEntity) bool

IsSandboxWorkspacePolicyRow reports whether e is the internal policy row.

func IsSkillMaintenanceDescription 

func IsSkillMaintenanceDescription(description string) bool

IsSkillMaintenanceDescription reports whether description is the reserved prefix that hides skill-install sessions from the console list.

func IsSyntheticUserID 

func IsSyntheticUserID(id string) bool

IsSyntheticUserID reports whether id refers to the synthetic system user that the X-API-Key auth path attaches to each tenant (User.ID = "system-<tenantID>"). These users have no real human behind them and no tenant_members row, so RBAC ownership matching against them is never meaningful — service-layer code that records "the creator" should skip storing this ID and treat the resource as tenant-owned instead.

Kept minimal on purpose: the prefix and "all digits afterwards" invariant comes from middleware/auth.go's User construction for the API-key branch. If that prefix changes, update both sides.

func IsSystemAdminFromContext 

func IsSystemAdminFromContext(ctx context.Context) bool

IsSystemAdminFromContext extracts the system admin flag from ctx. Returns false (fail-closed) when the key is absent.

func IsValidEngineType 

func IsValidEngineType(t RetrieverEngineType) bool

IsValidEngineType checks whether the given engine type is valid for VectorStore.

func IsValidFavoriteResourceType 

func IsValidFavoriteResourceType(t string) bool

IsValidFavoriteResourceType returns true for resource types this product currently supports favoriting. The handler validates against this list to keep clients from inserting arbitrary strings (which would balloon the table and break the frontend's segmented view).

func IsValidMemoryKind 

func IsValidMemoryKind(kind string) bool

IsValidMemoryKind validates a kind coming from an LLM response or the API.

func IsValidSessionKind added in v0.9.0 

func IsValidSessionKind(kind string) bool

func IsValidWikiPageStatus(status string) bool

IsValidWikiPageStatus reports whether status is one of the known statuses.

func IsValidWikiPageType 

func IsValidWikiPageType(pageType string) bool

IsValidWikiPageType reports whether pageType is one of the known page types. Unknown values would silently disappear from the type-filtered listings the browser is built on, so write paths reject them.

func KnowledgeFolderName 

func KnowledgeFolderName(path string) string

KnowledgeFolderName returns the display name of a folder path (its last segment). The root folder has no name.

func KnowledgeFolderParent 

func KnowledgeFolderParent(path string) string

KnowledgeFolderParent returns the parent folder path of the given path, or an empty string when the path is a root-level folder.

func LLMCallMetadataFromContext 

func LLMCallMetadataFromContext(ctx context.Context) (purpose, prefixFingerprint string)

LLMCallMetadataFromContext returns the cache-observability labels attached by the orchestration layer.

func LanguageFromContext 

func LanguageFromContext(ctx context.Context) (string, bool)

LanguageFromContext extracts the language locale string from ctx (e.g. "zh-CN", "en-US"). Returns ("zh-CN", false) when the key is absent.

func LanguageFromContextOrDefault 

func LanguageFromContextOrDefault(ctx context.Context) string

LanguageFromContextOrDefault returns the locale carried by ctx, falling back to DefaultLanguage(). Use it when persisting a locale onto an async task payload so downstream workers never inherit an empty language.

func LanguageLocaleName 

func LanguageLocaleName(locale string) string

LanguageLocaleName maps a locale code to a human-readable language name for LLM prompts.

func LanguageNameFromContext 

func LanguageNameFromContext(ctx context.Context) string

LanguageNameFromContext returns the human-readable language name for use in prompts. e.g. "zh-CN" -> "Chinese (Simplified)", "en-US" -> "English", "ko-KR" -> "Korean" Falls back to DefaultLanguage() (WEKNORA_LANGUAGE env, then "zh-CN").

func LoadAgentTypePresetsConfig 

func LoadAgentTypePresetsConfig(configDir string) error

LoadAgentTypePresetsConfig loads agent-type preset definitions from the given config directory (e.g. "./config"). The file must be named "agent_type_presets.yaml". Called once at startup (after LoadConfig determines the config directory).

If the file does not exist, this is a no-op and the registry stays empty — in that case the frontend will simply not offer the agent-type dropdown.

func LoadBuiltinAgentsConfig 

func LoadBuiltinAgentsConfig(configDir string) error

LoadBuiltinAgentsConfig loads built-in agent definitions from the given config directory (e.g. "./config"). The file must be named "builtin_agents.yaml". This should be called once at startup, after config.LoadConfig determines the config directory.

If the file does not exist, the function is a no-op and the hard-coded defaults in BuiltinAgentRegistry remain effective.

func LoadBuiltinModelsConfig 

func LoadBuiltinModelsConfig(ctx context.Context, db *gorm.DB, configDir string) error

LoadBuiltinModelsConfig reads builtin_models.yaml (or the path pointed to by BUILTIN_MODELS_CONFIG) and reconciles the YAML-managed slice of `models` with the file contents.

Lifecycle contract:

  • YAML loader only ever writes rows tagged managed_by="yaml". Rows created or explicitly overridden via UI/API/SQL (managed_by="") are detected by id and preserved, and are never modified.
  • Each YAML entry is UPSERTed by id, with deleted_at force-reset to NULL (so a row that was soft-deleted previously is resurrected when it reappears in the file).
  • After all UPSERTs, any pre-existing yaml-managed row whose id is no longer in the file is soft-deleted. Removing an entry from YAML is therefore the supported way to retire a built-in model — no manual SQL needed.
  • If is_default=true is set on a YAML entry, the loader first clears is_default on any other rows in the same (tenant_id, type) bucket, mirroring the invariant enforced by the API path. Multiple entries with is_default=true for the same bucket result in last-one-wins with a warning.

Failure handling:

  • file not found / mount point is a directory / path unset: no-op
  • YAML parse error: prints a warning and aborts the reconcile (the drift sweep is NOT run, so a malformed file cannot accidentally wipe YAML-managed rows)
  • per-entry UPSERT error: prints a warning, the entry is dropped from the "current YAML id set" so the sweep won't delete its existing row either (treats the failure as "leave alone")

func MCPConfigFingerprint 

func MCPConfigFingerprint(s *MCPService) string

MCPConfigFingerprint excludes display text and enabled state: editing documentation does not change upstream identity. Secrets affect identity but only their digest is stored.

func MCPEndpointAgentAllowed 

func MCPEndpointAgentAllowed(agent *CustomAgent, tenantID uint64) bool

MCPEndpointAgentAllowed reports whether an endpoint of tenantID may run agent for the ask tool. Tenant-owned agents qualify; builtins qualify only when they are user-facing (listed by GetBuiltinAgentIDs). Internal builtins such as the wiki fixer and the skill installer stay unreachable because they ship write and shell tools that the endpoint allowlist never covers.

func MCPEndpointCapabilitiesForTools 

func MCPEndpointCapabilitiesForTools(tools []string) []string

MCPEndpointCapabilitiesForTools derives the tenant API key capabilities an endpoint needs so its calls pass the same scope checks as a scoped API key.

func MapString 

func MapString(m map[string]interface{}, key string) string

MapString reads a string from a JSON-decoded map.

func MemoryAllowedForAgent 

func MemoryAllowedForAgent(ctx context.Context) bool

MemoryAllowedForAgent reports whether the agent handling this request permits memory. Absence of the marker means allowed, so every existing call site keeps working and only an explicit opt-out turns memory off.

func MemoryFingerprint 

func MemoryFingerprint(content string) string

MemoryFingerprint hashes the normalized statement. Tombstones keep only this hash, never the text: a user who asked to forget something should not have it retained in a second table under a different name.

func MemoryItemKey 

func MemoryItemKey(topic, content string) string

MemoryItemKey derives the conflict-detection key for a stored memory.

A memory's identity is its topic, not its wording: "生产库用的是 MySQL" and "生产库用的是 PostgreSQL" are the same note with a corrected value, and the second has to replace the first rather than sit beside it. That only works if two labels for the same subject produce the same key, which is why this uses the topic normaliser rather than the character-bag key below — the same reason topic counting needed it.

Content is the fallback when a statement arrives without a topic, where there is nothing better to key on and word order genuinely should not matter.

func MentionedItemsToRaw 

func MentionedItemsToRaw(items MentionedItems) []interface{}

MentionedItemsToRaw converts typed mentions into plain values that survive Redis JSON round-trips without a second unmarshal type on the read side.

func MustTenantIDFromContext 

func MustTenantIDFromContext(ctx context.Context) uint64

MustTenantIDFromContext extracts the tenant ID from ctx, panicking if missing.

func NeedsSandboxWriteCompletionBudget 

func NeedsSandboxWriteCompletionBudget(sandboxConfigID string) bool

NeedsSandboxWriteCompletionBudget reports whether this agent may register write_sandbox_file / edit_sandbox_file. Those tools follow the bound sandbox, not the allowed_tools checklist.

func NormalizeEmbedDefaultLocale 

func NormalizeEmbedDefaultLocale(locale string) string

NormalizeEmbedDefaultLocale returns a supported locale tag or empty string (meaning follow browser / host widget locale).

func NormalizeEmbedHeaderTitleMode 

func NormalizeEmbedHeaderTitleMode(mode string) string

NormalizeEmbedHeaderTitleMode returns a supported header title source.

func NormalizeEmbedWidgetPosition 

func NormalizeEmbedWidgetPosition(position string) string

NormalizeEmbedWidgetPosition returns a supported widget corner or the default.

func NormalizeImageRead 

func NormalizeImageRead(detail, focus string) (string, string)

NormalizeImageRead supplies the brief default and bounds the optional focus.

func NormalizeKnowledgeBasePromptInstructions 

func NormalizeKnowledgeBasePromptInstructions(kb *KnowledgeBase)

NormalizeKnowledgeBasePromptInstructions trims whitespace on all KB-scoped custom instruction fields before persistence.

func NormalizeKnowledgeFolderPath 

func NormalizeKnowledgeFolderPath(raw string) string

NormalizeKnowledgeFolderPath turns a client-supplied relative directory into the canonical form stored in knowledges.folder_path: forward-slash separated, no leading/trailing separator, no "." / ".." segments, depth and length capped. The zero value ("") means "knowledge base root".

func NormalizeMCPEndpointTools 

func NormalizeMCPEndpointTools(in []string) []string

NormalizeMCPEndpointTools drops unknown and duplicate names and returns the survivors in catalog order so the stored allowlist is canonical.

func NormalizeMemoryForMatch 

func NormalizeMemoryForMatch(content string) string

NormalizeMemoryForMatch collapses a statement to a comparable form: no case, no whitespace, no punctuation. Used both for containment de-duplication and for the fingerprint that suppresses a forgotten memory.

func NormalizeMemoryKey 

func NormalizeMemoryKey(key, content string) string

NormalizeMemoryKey derives the conflict-detection key for a statement. Callers may supply their own key (the extraction model is asked for one); when they do not, we fall back to the significant words of the content so two phrasings of the same fact still collide.

func NormalizePageView added in v0.9.0 

func NormalizePageView(view string) string

NormalizePageView trims and bounds a client-sent page or view title.

func NormalizeQueryText 

func NormalizeQueryText(q string) string

NormalizeQueryText 对搜索查询文本进行归一化处理 与 NormalizeQuestion 相同的处理逻辑，用于搜索时对查询文本进行归一化

func NormalizeQuestion 

func NormalizeQuestion(q string) string

NormalizeQuestion 对问题文本进行归一化处理以提高向量匹配命中率 处理顺序参考: query = convert_st(trim_url(query.lower().strip().strip("？。，；、：""！?.,;!:'\"")), 1) 1. 去除首尾空白 2. 移除 URL 3. 转小写 4. 去除首尾标点 5. 繁体转简体 6. 全角符号转半角 7. 智能空格处理（中文间去空格，英文/数字间保留）

func NormalizeSupportedLocale 

func NormalizeSupportedLocale(locale string) string

NormalizeSupportedLocale returns a trimmed, supported locale tag or an empty string when the value is blank or unsupported.

func NormalizeTopicKey 

func NormalizeTopicKey(topic string) string

NormalizeTopicKey reduces a topic label to a stable identity key.

This is deliberately NOT NormalizeMemoryKey, which sorts and de-duplicates characters. That behaviour is defensible for a memory item — where word order should not matter and a containment check catches what it misses — but as a topic identity it is wrong in both directions: it treats "门店排班管理" and "门店的排班管理" as different subjects because of one extra character, and it would treat two anagrams as the same one.

Order is preserved here, and only genuinely uninformative characters and trailing qualifiers are removed. Everything a model might vary that is not purely cosmetic — synonyms, different phrasings — is left for the resolver, which has more than string comparison available to it.

func NormalizeTopicList 

func NormalizeTopicList(topics []string, limit int) []string

NormalizeTopicList trims, bounds and deduplicates topic keywords while preserving the first spelling seen for each normalized key.

func NormalizeURL 

func NormalizeURL(text string, mode URLNormMode) string

NormalizeURL 根据指定模式处理文本中的 URL

func NormalizeWikiEditSource 

func NormalizeWikiEditSource(source string) string

NormalizeWikiEditSource maps unknown / empty values to WikiEditSourcePipeline so legacy rows and forgotten call sites degrade to the historical behavior ("the machine wrote this").

func NumberAttachmentImages 

func NumberAttachmentImages(content string, images []TemporaryDocumentImage) string

NumberAttachmentImages marks every markdown image that refers to one of images with its 1-based position, so a reader of the text knows which image to request. Unknown references are left unmarked.

func OptionalUint32 

func OptionalUint32(v int) *uint32

OptionalUint32 converts int to *uint32 for Qdrant SDK. Returns nil for values <= 0, which tells Qdrant to use its server default.

func OverrideBuiltinAgentEntriesForTest 

func OverrideBuiltinAgentEntriesForTest(entries map[string]*BuiltinAgentEntry) func()

OverrideBuiltinAgentEntriesForTest replaces the in-memory YAML registry. Tests in other packages use this to assert locale overlays; call the returned func to restore the previous map. Concurrent tests are serialized so they do not clobber each other's entries.

func ParseAgentSourceTenantID 

func ParseAgentSourceTenantID(raw string) (uint64, error)

ParseAgentSourceTenantID parses the optional shared-agent source workspace selector. Empty or whitespace input is treated as absent (0, nil). Non-empty but invalid values return an error so callers fail closed instead of silently falling back.

func ParseArtifactModTime 

func ParseArtifactModTime(s string) time.Time

ParseArtifactModTime decodes message_artifacts.mod_time; anything unparseable reads as the zero time, which only costs the collector a hash.

func ParseProviderScheme 

func ParseProviderScheme(filePath string) string

ParseProviderScheme extracts the provider from a provider:// scheme path. e.g. "minio://bucket/key" → "minio", "local://tenant/file.pdf" → "local" Returns "" if the path does not use a known provider scheme.

func ParseResourcePath 

func ParseResourcePath(value string) (string, bool)

ParseResourcePath validates and extracts a canonical resource handle.

func ParseStorageBackendPath 

func ParseStorageBackendPath(path string) (backendID, providerPath string, ok bool)

func ParseWikiSourceRef 

func ParseWikiSourceRef(ref string) (knowledgeID, title string)

ParseWikiSourceRef splits a source_refs entry into its durable knowledge ID and optional display title. Entries are stored as "uuid" or "uuid|title"; both halves are trimmed and a leading "|" yields an empty ID. This is the only parser of the format: every reader must go through it so that a ref with stray whitespace resolves identically on the scope-authorization, deletion, lint, and rendering paths.

func PlaceholderMap 

func PlaceholderMap() map[PromptFieldType][]PromptPlaceholder

PlaceholderMap returns a map of field types to their available placeholders

func PreprocessObservesGeometry added in v0.9.0 

func PreprocessObservesGeometry(mode string) bool

PreprocessObservesGeometry reports whether the describe round should ask the geometry attributes; PreprocessRunsUnconditionally reports whether the page is straightened without consulting them. The three modes are mutually exclusive, so a caller reads exactly one of these.

An empty mode answers false to both, which is the honest answer for a caller that read a switch nobody offers: a pipeline that does not declare the setting has no reason to ask the model about geometry it could not use.

func PreprocessRunsUnconditionally added in v0.9.0 

func PreprocessRunsUnconditionally(mode string) bool

PreprocessRunsUnconditionally is the other half of the pair above: the mode that straightens every page without asking, which is also why it leaves the describe prompt alone (there is no question to ask).

func PreserveIfRedacted 

func PreserveIfRedacted(incoming, existing string) string

PreserveIfRedacted returns existing when incoming is empty or the redacted placeholder, otherwise returns incoming.

func PrincipalAuthSourceFromContext added in v0.9.0 

func PrincipalAuthSourceFromContext(ctx context.Context) string

PrincipalAuthSourceFromContext returns "" when no auth middleware ran.

func QuestionGenerationActive added in v0.9.0 

func QuestionGenerationActive(kb *KnowledgeBase) bool

QuestionGenerationActive reports whether a document knowledge base still wants generated questions in retrieval. FAQ knowledge bases index their own similar questions under the same source-id shape and are never treated as this switch.

func QuestionGenerationDisabled added in v0.9.0 

func QuestionGenerationDisabled(kb *KnowledgeBase) bool

QuestionGenerationDisabled reports whether generated-question rows for a document knowledge base must stay out of recall and rerank. A nil config is off: question generation only runs when the switch is explicitly enabled.

func QuestionGenerationOffIDs added in v0.9.0 

func QuestionGenerationOffIDs(kbs []*KnowledgeBase) map[string]struct{}

QuestionGenerationOffIDs returns document knowledge bases whose generated questions must stay out of rerank passages.

func QueueForTaskType 

func QueueForTaskType(taskType string) (string, bool)

QueueForTaskType returns the declared queue for a task type. Producers still pass the queue explicitly to asynq, while tests and observability can use this mapping to detect drift.

func QueueWeightsForPool 

func QueueWeightsForPool(pool string) map[string]int

QueueWeightsForPool returns the asynq queue configuration for one worker pool. An empty map indicates a programming error in the pool declaration.

func QueueWeightsForSharedPool 

func QueueWeightsForSharedPool() map[string]int

QueueWeightsForSharedPool returns the core/enrichment queues eligible for elastic capacity. Post-process and maintenance are deliberately excluded: post-process needs a small latency guarantee, while long maintenance tasks must not pin burst capacity intended for the user-facing pipeline.

func RedactSensitive 

func RedactSensitive(content string) (string, bool)

RedactSensitive removes credentials and identity numbers from a statement. The second return value reports whether anything was removed.

func RegisterGalleryAttrSource 

func RegisterGalleryAttrSource(id string, fn func(kbID string) []GalleryAttrDef)

RegisterGalleryAttrSource adds an attribute source to the gallery's open registry. Registration order is priority order: when two sources declare the same source-local attribute name, the namespaced ids keep both alive ("system:keyword" vs "kb:keyword"), and earlier-registered sources win raw-key lookups on tie. Call from init(); a nil fn or a malformed / duplicate id is a programming error and panics loudly.

func RenderMemoryBlock 

func RenderMemoryBlock(items []*MemoryItem) string

RenderMemoryBlock renders items as the resident block stored on the subject. Items are grouped by kind and truncated to MemoryBlockRuneBudget.

func RenderMemoryRecall 

func RenderMemoryRecall(items []*MemoryItem) string

RenderMemoryRecall renders query-matched situational items for one turn.

func RenderPromptPlaceholders 

func RenderPromptPlaceholders(template string, vals PlaceholderValues) string

RenderPromptPlaceholders replaces all {{key}} occurrences in template with the corresponding values from vals. Unknown placeholders are left untouched.

Built-in auto-values (filled when not supplied explicitly):

  • {{current_time}} -> time.Now().Format("2006-01-02") (date only; clock precision would bust provider prefix caches on every request)
  • {{current_week}} -> current weekday name
  • {{yesterday}} -> yesterday's date (2006-01-02)

func RequestIDFromContext 

func RequestIDFromContext(ctx context.Context) (string, bool)

RequestIDFromContext extracts the request ID string from ctx.

func ResolveAgentTypePresetPromptRefs 

func ResolveAgentTypePresetPromptRefs(resolver func(id string) string)

ResolveAgentTypePresetPromptRefs iterates over all presets and resolves system_prompt_id references into the actual prompt template content via the provided resolver. This lets downstream services treat the `system_prompt_id` field as a concrete prompt string if they need to.

We keep system_prompt_id as-is in the preset (it's also what the editor writes back to CustomAgentConfig), so this hook is only used to validate that every referenced template actually exists at startup.

func ResolveBuiltinAgentPromptRefs 

func ResolveBuiltinAgentPromptRefs(resolver func(id string) string)

ResolveBuiltinAgentPromptRefs iterates over all builtin agent entries and resolves system_prompt_id / context_template_id references by calling the provided resolver function. The resolver takes a template ID and returns the template content string (empty string if not found).

This must be called after both LoadBuiltinAgentsConfig and prompt template loading have completed.

func ResolveCollectionName 

func ResolveCollectionName(ic *IndexConfig, envKey, defaultVal string) string

ResolveCollectionName returns the collection name from IndexConfig, falling back to env var and then default. Priority: CollectionPrefix > CollectionName > env var > defaultVal. CollectionPrefix is checked first because Qdrant/Weaviate use it as the base name. CollectionName (Milvus) is checked second. If both are set, CollectionPrefix wins — this is safe because each VectorStore has a single engine type, so only one field is relevant.

func ResolveIndexName 

func ResolveIndexName(ic *IndexConfig, envKey, defaultVal string) string

ResolveIndexName returns the index name from IndexConfig, falling back to env var and then default. Used by Repository constructors. For service-layer duplicate checking, use GetIndexNameOrDefault instead.

func ResolveLanguage 

func ResolveLanguage(ctx context.Context, locale string) string

ResolveLanguage resolves the effective locale for work that may carry its own language, in descending precedence: the explicit locale, the locale in ctx, then DefaultLanguage().

Async workers must use this rather than reading a payload field directly: a task payload persisted before the language field existed, or enqueued from a background path that never passed through the HTTP language middleware, carries an empty locale. Interpolating that empty value into a prompt yields instructions like "Write in ." and lets the model pick a language at random.

func ResolveLanguageName 

func ResolveLanguageName(ctx context.Context, locale string) string

ResolveLanguageName is ResolveLanguage rendered as the human-readable name that prompt templates interpolate (e.g. "Chinese (Simplified)").

It is idempotent over already-resolved names: LanguageLocaleName passes unknown values through, so re-resolving a display name returns it unchanged.

func ResolveMinerUParseMethod 

func ResolveMinerUParseMethod(method string, legacyOCREnabled *bool) string

ResolveMinerUParseMethod normalizes the explicit MinerU parse method and maps the legacy OCR toggle to the closest safe behavior. The old enabled value maps to auto instead of ocr so digital PDFs keep their native text layer while scanned PDFs are still detected and OCRed by MinerU.

func RunsInSharedKBWorkspace added in v0.9.0 

func RunsInSharedKBWorkspace(agent *CustomAgent) bool

RunsInSharedKBWorkspace reports whether a built-in agent opened on one shared knowledge base runs in that KB's source workspace when the caller may edit it, so KB-scoped models and Wiki tools resolve there.

func SandboxTenantIDFromContext 

func SandboxTenantIDFromContext(ctx context.Context) (uint64, bool)

SandboxTenantIDFromContext returns the tenant to key session→sandbox bindings by. It falls back to TenantIDFromContext, which is correct for every path that never borrows another workspace's tenant: there the request tenant already IS the session owner.

func SanitizeClientSessionDescription 

func SanitizeClientSessionDescription(incoming, existing string) string

SanitizeClientSessionDescription keeps the skill-maintenance marker off client-writable descriptions. A row that is already a maintenance session keeps its stored description so a PUT cannot un-hide it; any other row drops a planted marker rather than accepting it.

func SanitizeMemoryContent 

func SanitizeMemoryContent(content string) string

SanitizeMemoryContent trims a statement to a single line within the length budget. Memory is injected into the system prompt, so newlines and control characters are collapsed to keep an item from forging prompt structure.

func SanitizeMemoryTopic 

func SanitizeMemoryTopic(topic string) string

SanitizeMemoryTopic normalizes the readable subject to a single short line.

func SanitizeStrings 

func SanitizeStrings(values []string) []string

SanitizeStrings 对字符串列表进行基础清理（TrimSpace + 去重）

func ScanResourceReferences 

func ScanResourceReferences(text string) []string

ScanResourceReferences returns every distinct resource:// reference embedded in text, in order of first appearance.

Rich text (a chat answer, a manual knowledge document) is the only place a reference's owner can be discovered after the fact: the body is what gets copied between a message and a knowledge entry, so re-binding on copy starts by reading the handles back out of it.

func SearchResultKnowledgeBaseIDs added in v0.9.0 

func SearchResultKnowledgeBaseIDs(results []*SearchResult) []string

SearchResultKnowledgeBaseIDs returns the distinct knowledge base IDs on results.

func SessionIDFromContext 

func SessionIDFromContext(ctx context.Context) (string, bool)

SessionIDFromContext extracts the current session ID from ctx. Returns ("", false) when the key is absent or the value is not a non-empty string.

func SessionListSourceRequiresAdmin 

func SessionListSourceRequiresAdmin(source string) bool

SessionListSourceRequiresAdmin reports whether a session-list source filter exposes tenant-wide channel traffic (API / IM / embed) in the Web console.

func SessionOwnerIDFromContext 

func SessionOwnerIDFromContext(ctx context.Context) string

SessionOwnerIDFromContext returns the sessions.user_id scope for the current caller. API external users and embed chat sessions use principal-derived IDs; tenant API keys are isolated per key id; MCP OAuth token storage uses MCPOAuthPrincipalFromContext (visitor-level for embed).

PrincipalMCPEndpoint must resolve to StorageID() too: the MCP `ask` tool creates its session with `MCPEndpointPrincipal(...).StorageID()` and then looks it up through this function. Without the case below the lookup falls through to the raw user id ("mcp-<endpointID>"), which never matches the stored owner ("mcp_endpoint:<tenantID>:<endpointID>"), so every ask call failed with "failed to create user message: session not found".

func SessionRequiresAdminConsoleRead 

func SessionRequiresAdminConsoleRead(s *Session, imPlatform string) bool

SessionRequiresAdminConsoleRead reports whether a session row is channel- managed traffic that non-admin web users must not open from the console.

func SessionTenantIDFromContext 

func SessionTenantIDFromContext(ctx context.Context) (uint64, bool)

SessionTenantIDFromContext extracts the session-owner tenant ID from ctx. Falls back to TenantIDFromContext when the session key is absent.

func SetPreferParserEngine 

func SetPreferParserEngine(fn func(fileType string) string)

SetPreferParserEngine registers a build-time preference used by DefaultParserEngine. Pass nil to clear. Intended to be called from init().

func SharedAgentIncludesKB 

func SharedAgentIncludesKB(agent *CustomAgent, kb *KnowledgeBase) bool

SharedAgentIncludesKB also binds an "all" selection to the agent's tenant.

func SlotKey added in v0.9.0 

func SlotKey(pipelineID, key string) string

SlotKey namespaces a pipeline-private key with the pipeline that owns it. A key already carrying this pipeline's own namespace — an action scoped to one pipeline, whose id is "<pipeline>.<action>" — is left alone, so the pipeline id is never doubled. The runtime lookup in the image service and the settings panel, through its own mirror, both go through it, so a stored key is read the way it was written.

func SplitGalleryAttrID 

func SplitGalleryAttrID(id string) (sourceID, name string, ok bool)

SplitGalleryAttrID splits a namespaced attribute id back into its source id and source-local name. ok is false for ids without a separator.

func SplitKnowledgeRelativePath 

func SplitKnowledgeRelativePath(raw string) (folderPath string, fileName string)

SplitKnowledgeRelativePath splits an upload path such as "docs/spec/design.md" into its normalized folder path ("docs/spec") and its base file name ("design.md"). A plain file name yields an empty folder path, so callers can pass the raw `fileName` form field unconditionally.

func SplitWikiPageTypes 

func SplitWikiPageTypes(raw string) []string

SplitWikiPageTypes parses a page_type value that may carry several comma-separated types (e.g. "entity,concept") into a deduplicated slice, dropping blanks. An empty/whitespace-only input yields nil ("no filter"). Shared by the handler (query parsing) and repository (List filter) so the two layers split identically.

func StampSessionOwnerSource added in v0.9.0 

func StampSessionOwnerSource(ctx context.Context, s *Session)

StampSessionOwnerSource overwrites the owner's authentication source from the verified request context. The caller's credentials only vouch for a row whose owner is the caller's own owner scope; anything else (internal services, a row created on someone's behalf) is recorded as internal. The owner's kind is not stored: it follows from the source and user_id.

func SteerMessageContent 

func SteerMessageContent(content string) string

SteerMessageContent adds delivery context only to model input. The persisted user message and the UI always retain the user's original text.

func SubtreeChildID 

func SubtreeChildID(parentExternalID, kind, token string) string

SubtreeChildID builds the external_id of a sub-item fanned out from a parent source node — e.g. a docx node's attachment or embedded image. The shape is "<parentExternalID>#<kind>#<token>". The '#' separator is the contract the subtree sweep depends on (see SubtreeChildPrefix and FetchedItem.ReplacesSubtree): producers MUST build child IDs with this helper so the producer and the sweep consumer share one source of truth. kind is a short discriminator ("file", "image"); token is the source system's id for the child and is assumed to be '#'-free (Feishu/Notion/etc. tokens are).

func SubtreeChildPrefix 

func SubtreeChildPrefix(parentExternalID string) string

SubtreeChildPrefix is the external_id prefix that matches every child of a parent node built with SubtreeChildID. The sweep deletes prior children whose external_id starts with this prefix and are absent from SubtreeKeep. It must move in lockstep with SubtreeChildID: both encode the same '#' separator.

func TaskRetryMetadataFromContext 

func TaskRetryMetadataFromContext(ctx context.Context) (retried, maxRetry int, ok bool)

TaskRetryMetadataFromContext returns retry counters supplied by a non-Asynq task executor. The boolean is false for ordinary request contexts.

func TenantIDFromContext 

func TenantIDFromContext(ctx context.Context) (uint64, bool)

TenantIDFromContext extracts the execution tenant ID from ctx. Authorization should use CallerFromContext instead. Returns (0, false) when the key is absent or the value is not uint64.

func TopicIsSpecificEnoughToMatchLoosely 

func TopicIsSpecificEnoughToMatchLoosely(topic string) bool

TopicIsSpecificEnoughToMatchLoosely gates fuzzy matching.

Graphiti skips fuzzy matching for low-entropy names for the same reason: on a two-character label, a single shared bigram is most of the score, so fuzzy matching mostly produces false merges. Short labels fall through to the resolver's slower and more accurate tier instead.

func TopicKey 

func TopicKey(topic string) string

TopicKey folds a topic keyword into the key used for counting across documents: lower-cased, whitespace-collapsed, trailing punctuation removed. "Kubernetes " and "kubernetes." count as one topic; "K8s" stays separate and is left for the model to merge when it writes the knowledge-base gist.

func TopicLabelIsAnImprovement 

func TopicLabelIsAnImprovement(canonical, incoming, proposed string) bool

TopicLabelIsAnImprovement reports whether a proposed label may replace the canonical one when two subjects merge.

The label that survives a merge is currently just whichever arrived first, which is arbitrary — and it matters, because interests are fed to the query rewriter as vocabulary and shown to the user as what we think they care about. Letting the model propose a better name is worth doing, but it opens a ratchet: a model asked to name what two labels have in common will reach for something broader every time, and after a few merges the subject is an umbrella that means nothing.

So a replacement has to be more complete, never more general. This mirrors what entity-resolution systems that do rename converge on — Graphiti keeps the more specific node when collapsing duplicates, and LLM-driven merges in the wild pick the fullest form of a name rather than a category for it.

func TopicLooksLikeOneQuestion 

func TopicLooksLikeOneQuestion(topic string) bool

TopicLooksLikeOneQuestion reports whether a label names an individual query rather than a subject.

A subject has to recur to be worth anything: it is counted, and only becomes a memory once several conversations touch it. A label like "v2.3版本orders接口分页参数默认值查询" can only ever match itself, so it is counted once and then sits at one hit forever — the counting mechanism is dead and nothing says so.

Length is a blunt proxy, but a subject that cannot be named in a couple of dozen characters is carrying the parameters of one question. This does not reject anything: throwing the label away would lose the signal entirely, and the fix belongs in the prompt. It exists so the failure is visible in logs instead of only in a trace someone happens to open.

func TopicSimilarity 

func TopicSimilarity(a, b string) float64

TopicSimilarity scores two topic labels on shared character bigrams.

Bigrams rather than whole words because Chinese has no word separators, and Dice rather than Jaccard because it is more forgiving of one label being longer than the other — which is the common case when a model elaborates ("排班管理" vs "门店排班管理").

func TrimWikiFolderSegments 

func TrimWikiFolderSegments(parts []string) []string

TrimWikiFolderSegments keeps folder path segments verbatim, dropping only blank entries. Folder names are validated on creation (no separators), and the folder tree is the source of truth for a page's placement, so unlike CleanWikiCategoryPath no page-type filtering, deduplication, or depth cap applies: a user may legitimately name a folder "概念" or "Concepts".

func UploadOnlyQuestion 

func UploadOnlyQuestion(locale string) string

UploadOnlyQuestion is the question asked on the user's behalf when a message carries an image or file but no text. The stored user message keeps its empty text; only model input uses this question.

func UserIDFromContext 

func UserIDFromContext(ctx context.Context) (string, bool)

UserIDFromContext extracts the user ID string from ctx.

func UsesWorkspaceModelFallback added in v0.9.0 

func UsesWorkspaceModelFallback(agent *CustomAgent) bool

UsesWorkspaceModelFallback reports whether a built-in agent runs without its own model_id and rerank_model_id. These agents are hidden from agent management, so a user cannot configure them; the run resolves the chat model from its knowledge base or the system KnowledgeQA default, and the rerank model from the workspace.

func ValidateAskUserResponse added in v0.9.0 

func ValidateAskUserResponse(request, response json.RawMessage) error

ValidateAskUserResponse is the broker validator of AgentPromptKindAskUser.

func ValidateEffectiveProcessPromptInstructions 

func ValidateEffectiveProcessPromptInstructions(eff EffectiveProcessConfig) error

ValidateEffectiveProcessPromptInstructions checks length limits on the merged per-upload effective config.

func ValidateEmbedVisitorID 

func ValidateEmbedVisitorID(id string) error

ValidateEmbedVisitorID checks the client-supplied anonymous visitor id.

func ValidateIndexConfig 

func ValidateIndexConfig(ic IndexConfig) error

ValidateIndexConfig checks IndexConfig fields for safe values. Call this from the service layer before persisting a VectorStore.

func ValidateKnowledgeBasePromptInstructions 

func ValidateKnowledgeBasePromptInstructions(kb *KnowledgeBase) error

ValidateKnowledgeBasePromptInstructions checks length limits on KB-scoped custom instruction fields.

func ValidatePageActionResponse added in v0.9.0 

func ValidatePageActionResponse(request, response json.RawMessage) error

ValidatePageActionResponse is the broker validator of AgentPromptKindPageAction.

func ValidateSandboxNetworkPolicy 

func ValidateSandboxNetworkPolicy(cfg *TenantSandboxConfig) error

ValidateSandboxNetworkPolicy rejects a policy the provider would refuse, or would silently accept without doing what the admin meant. Errors are plain values; the service layer wraps them as bad-request responses.

func WikiEditSourceFromContext 

func WikiEditSourceFromContext(ctx context.Context) string

WikiEditSourceFromContext returns the wiki edit source carried by ctx, defaulting to WikiEditSourcePipeline when absent.

func WikiFolderPathSegments 

func WikiFolderPathSegments(path string) []string

WikiFolderPathSegments splits a materialized folder path ("AI/RAG") into its literal segments. An empty/blank path yields nil (the wiki root).

func WikiShrinkAllowedFromContext 

func WikiShrinkAllowedFromContext(ctx context.Context) bool

WikiShrinkAllowedFromContext reports whether ctx was marked with WithWikiShrinkAllowed.

func WikiSourceKnowledgeID 

func WikiSourceKnowledgeID(ref string) string

WikiSourceKnowledgeID extracts the knowledge id from a source_refs entry, stored as "uuid" or "uuid|title".

func WikiSourceRefMatchesKnowledge 

func WikiSourceRefMatchesKnowledge(ref, knowledgeID string) bool

WikiSourceRefMatchesKnowledge reports whether a source_refs entry points at the given knowledge ID, in either the bare or the "uuid|title" form.

func WithAccessLevel added in v0.9.0 

func WithAccessLevel(ctx context.Context, level AssistantAccessLevel) context.Context

WithAccessLevel records the run's effective access level.

func WithAuditAPIKey 

func WithAuditAPIKey(ctx context.Context, key AuditAPIKey) context.Context

func WithAuditAgentAction added in v0.9.0 

func WithAuditAgentAction(ctx context.Context, a AuditAgentAction) context.Context

WithAuditAgentAction attaches the agent action mutations in ctx belong to.

func WithBackgroundTask 

func WithBackgroundTask(ctx context.Context) context.Context

WithBackgroundTask marks ctx as originating from an asynq background worker (document parse / summary / question / graph / multimodal enrichment). The chat concurrency governor throttles only background LLM traffic, so this flag determines whether the per-model concurrency limit applies. See BackgroundTaskContextKey.

func WithCaller 

func WithCaller(ctx context.Context, caller Caller) context.Context

WithCaller captures the authenticated identity independently of execution scope.

func WithEmbedQuery 

func WithEmbedQuery(ctx context.Context) context.Context

WithEmbedQuery marks ctx as embedding a search query rather than content being indexed. Asymmetric retrieval models encode the two sides differently and lose accuracy when a query is embedded as a passage; the embedding layer turns the mark into the vendor's own parameter where it has one.

func WithEmbedVisitorID 

func WithEmbedVisitorID(ctx context.Context, visitorID string) context.Context

func WithExecutionTenant 

func WithExecutionTenant(ctx context.Context, tenantID uint64) context.Context

WithExecutionTenant changes repository/model scope, never authorization. It does not grant access to any resources in the destination tenant.

func WithGrantScope added in v0.9.0 

func WithGrantScope(ctx context.Context, scope GrantScope) context.Context

WithGrantScope records where the run's grants live.

func WithInternalDispatch added in v0.9.0 

func WithInternalDispatch(ctx context.Context, d InternalDispatch) context.Context

WithInternalDispatch marks ctx as an in-process call made as d's user. An incomplete identity leaves ctx unmarked.

func WithLLMCallMetadata 

func WithLLMCallMetadata(ctx context.Context, purpose, prefixFingerprint string) context.Context

WithLLMCallMetadata annotates a provider call for cache observability. The fingerprint must be a hash, never raw prompt content.

func WithMCPOAuthNonInteractive 

func WithMCPOAuthNonInteractive(ctx context.Context) context.Context

WithMCPOAuthNonInteractive marks ctx as originating from a channel that cannot complete an in-conversation MCP OAuth prompt (e.g. an IM bot). The agent uses this to emit a one-shot authorization notice instead of blocking on the OAuth wait until it times out. See MCPOAuthNonInteractiveContextKey.

func WithMemoryDisabled 

func WithMemoryDisabled(ctx context.Context) context.Context

WithMemoryDisabled marks the current request as not allowed to read memory.

func WithPrincipal 

func WithPrincipal(ctx context.Context, principal Principal) context.Context

func WithPrincipalAuthSource added in v0.9.0 

func WithPrincipalAuthSource(ctx context.Context, source string) context.Context

WithPrincipalAuthSource records how the request's principal was verified.

func WithRunMode added in v0.9.0 

func WithRunMode(ctx context.Context, m RunMode) context.Context

WithRunMode attaches the run's mode to ctx.

func WithSandboxTenantID 

func WithSandboxTenantID(ctx context.Context, tenantID uint64) context.Context

WithSandboxTenantID records the session-owner tenant that session→sandbox bindings must be keyed by, independently of the tenant the rest of the pipeline runs as. Callers set it wherever they swap TenantIDContextKey for a shared agent's workspace.

func WithSessionID 

func WithSessionID(ctx context.Context, sessionID string) context.Context

WithSessionID returns a derived context carrying the current session ID. Stateful sandbox backends (e.g. CubeSandbox) rely on this key to route script execution to the per-session persistent MicroVM instance.

func WithStandingGrantScope added in v0.9.0 

func WithStandingGrantScope(ctx context.Context, scope GrantScope) context.Context

WithStandingGrantScope records grants the run may use but never adds to: an automation's, approved in its settings. Approvals given during the run go to the run's own scope.

func WithTaskRetryMetadata 

func WithTaskRetryMetadata(ctx context.Context, retried, maxRetry int) context.Context

WithTaskRetryMetadata records retry counters for task executors that do not provide Asynq's native worker context, notably the Lite synchronous executor.

func WithTenantAPIKeyScope 

func WithTenantAPIKeyScope(ctx context.Context, scope TenantAPIKeyScope) context.Context

func WithWikiEditSource 

func WithWikiEditSource(ctx context.Context, source string) context.Context

WithWikiEditSource marks ctx so wiki page writes performed under it are attributed to the given edit source (WikiEditSourceUser / Agent / Revert). Writes without the mark are attributed to the ingest pipeline.

func WithWikiShrinkAllowed 

func WithWikiShrinkAllowed(ctx context.Context) context.Context

WithWikiShrinkAllowed marks ctx so ONE wiki page write may drop table rows the stored page still carries.

UpdatePage refuses such a write by default, because a model asked to re-emit a whole page silently returns it with rows missing and the page then shrinks with no trace. Callers that are removing content on purpose — a retraction after a source document was deleted, an exact-text replacement that deletes rows — say so here, and only for the write that does it.

func WrapMemoryForPrompt 

func WrapMemoryForPrompt(block, recall string) string

WrapMemoryForPrompt wraps rendered memory in a labelled envelope. The label states that the content is background data and not instructions. Escaping preserves that boundary; it does not enforce tool permissions. Returns "" for empty input so callers can append unconditionally.

Types

type APIKeyCapability 

type APIKeyCapability string

APIKeyCapability is a bounded grant on a tenant API key. See TenantAPIKey.Capabilities.

	APIKeyCapabilityIngest APIKeyCapability = "ingest"
	// APIKeyCapabilityManageKnowledgeBases lets a scoped key manage the full
	// knowledge-base lifecycle: create, copy, duplicate, rename/reconfigure,
	// and delete. For operations that target an existing KB (copy/duplicate
	// source, update, delete) the key's allowed KB scope still bounds which
	// KBs it may touch; create has no source to bound against, so a
	// scope-restricted key may add a new KB to its tenant (same-tenant, no
	// cross-tenant reach — the new KB simply falls outside the key's
	// allow-list and stays unmanageable by it). It is separate from ingest:
	// uploading or editing KB contents does not imply permission to manage
	// the KB itself.
	APIKeyCapabilityManageKnowledgeBases APIKeyCapability = "manage_kbs"
	// APIKeyCapabilityManageAgents lets a key create/read/update/delete/copy

	APIKeyCapabilityManageAgents APIKeyCapability = "manage_agents"
	// APIKeyCapabilityMessageHistory lets a key search and inspect the
	// tenant-level chat-history knowledge base without granting full Owner

	// back to the tenant-level principal.
	RequireDirectHeader bool   `json:"require_direct_header,omitempty"`
	HMACSecret          string `json:"hmac_secret,omitempty"`
}

APIPrincipalConfig controls how tenant API-key requests map to terminal principals. Direct header mode is low-assurance and should only be used for trusted server-to-server calls; signed-token mode verifies the user claim.

func (*APIPrincipalConfig) Scan 

func (c *APIPrincipalConfig) Scan(value interface{}) error

func (*APIPrincipalConfig) Value

}

AgentConfig represents the full agent configuration (used at tenant level and runtime) This includes all configuration parameters for agent execution

func (*AgentConfig) CitationsEnabled 

func (c *AgentConfig) CitationsEnabled() bool

CitationsEnabled preserves citation output for legacy runtime configs that predate the setting and therefore have a nil CitationEnabled value.

func (*AgentConfig) EnableSkillInstallMode 

func (c *AgentConfig) EnableSkillInstallMode(agentID, skillDir string)

EnableSkillInstallMode grants install-mode shell execution to the built-in skill installer agent and to nothing else, scoped to the skill directory it was started for. The agent ID is checked here rather than at the call site so there is exactly one place to audit.

The privilege and its scope are granted together: a caller cannot obtain the root shell without naming the directory the file tools will be confined to. skillDir is stored verbatim and validated where the tools are constructed — types cannot import the sandbox package that owns the path rules.

func (*AgentConfig) ResolveSystemPrompt 

func (c *AgentConfig) ResolveSystemPrompt(webSearchEnabled bool) string

ResolveSystemPrompt returns the prompt template for the given web search state. It uses the unified SystemPrompt field, falling back to deprecated fields for backward compatibility.

	CreatedAt     time.Time  `json:"created_at"`
	UpdatedAt     time.Time  `json:"updated_at"`
}

AgentPrompt is one prompt raised by an agent run. Kind decides the shape of Request and Response; the row is the source of truth for the answer and process memory only holds a wake-up hook.

func (*AgentPrompt) BeforeCreate added in v0.9.0 

func (p *AgentPrompt) BeforeCreate(_ *gorm.DB) error

BeforeCreate sets ID for AgentPrompt.

func (*AgentPrompt) IsOpen added in v0.9.0

	UpdatedAt          time.Time `json:"updated_at"`
}

AgentRunSuspension is the persisted state of a run blocked on a prompt, so any replica can resume it once the prompt is answered. Snapshot is opaque outside the agent engine and versioned by SnapshotVersion.

func (AgentRunSuspension) TableName added in v0.9.0 

func (AgentRunSuspension) TableName() string

TableName pins the table name.

AgentShareResponse represents an agent share record in API responses

type AgentState 

type AgentState struct {
	PendingSteerMessages []string              `json:"-"`
	PendingBackground    []BackgroundInjection `json:"-"`

	Suspended     *PromptSuspension `json:"-"`
	SuspendedStep *AgentStep        `json:"-"`
}

AgentState tracks the execution state of an agent across iterations

type AgentStep 

type AgentStep struct {
	Iteration int    `json:"iteration"` // Iteration number (0-indexed)
	Thought   string `json:"thought"`   // LLM's reasoning/thinking (Think phase)
	// Progress is user-facing commentary from a non-terminal round. Thought stays intact for model replay.

	UserMessagesBefore []string `json:"user_messages_before,omitempty"`
	// BackgroundInjections are background-work messages delivered before this
	// model response, after the step's steered messages, in delivery order.
	BackgroundInjections []BackgroundInjection `json:"background_injections,omitempty"`

	Truncated bool `json:"truncated,omitempty"`
}

AgentStep represents one iteration of the ReAct loop

func (*AgentStep) GetObservations 

func (s *AgentStep) GetObservations() []string

GetObservations returns observations from all tool calls in this step This is a convenience method to maintain backward compatibility

type AgentSteps 

type AgentSteps []AgentStep

AgentSteps represents a collection of agent execution steps Used for storing agent reasoning process in database

func (*AgentSteps) Scan 

func (a *AgentSteps) Scan(value interface{}) error

Scan implements the sql.Scanner interface for database deserialization

func (AgentSteps) Value 

func (a AgentSteps) Value() (driver.Value, error)

Value implements the driver.Valuer interface for database serialization

type AgentTypeKBFilter 

type AgentTypeKBFilter struct {
	// AnyOf: KB must expose at least ONE of these capability flags.
	AnyOf []string `yaml:"any_of"  json:"any_of,omitempty"`
	// AllOf: KB must expose ALL of these capability flags.
	AllOf []string `yaml:"all_of"  json:"all_of,omitempty"`
	// NoneOf: KB must expose NONE of these capability flags.
	NoneOf []string `yaml:"none_of" json:"none_of,omitempty"`
}

AgentTypeKBFilter describes how the agent editor should filter selectable KBs when this preset is active. Predicates are evaluated against the KB's capabilities (see KBCapabilities).

If all three slices are empty, the preset imposes no KB restriction.

type AgentTypePresetConfig 

type AgentTypePresetConfig struct {
	SystemPromptID         string   `yaml:"system_prompt_id"       json:"system_prompt_id,omitempty"`
	Temperature            float64  `yaml:"temperature"            json:"temperature,omitempty"`
	MaxIterations          int      `yaml:"max_iterations"         json:"max_iterations,omitempty"`
	AllowedTools           []string `yaml:"allowed_tools"          json:"allowed_tools,omitempty"`
	RetainRetrievalHistory bool     `yaml:"retain_retrieval_history" json:"retain_retrieval_history,omitempty"`
	FAQPriorityEnabled     bool     `yaml:"faq_priority_enabled"   json:"faq_priority_enabled,omitempty"`
	WebSearchEnabled       bool     `yaml:"web_search_enabled"     json:"web_search_enabled,omitempty"`
	SupportedFileTypes     []string `yaml:"supported_file_types"   json:"supported_file_types,omitempty"`
	// KBSelectionMode presets the KB picker mode: "all" | "selected" | "none".
	// When empty, the user's current value stays untouched.
	KBSelectionMode string `yaml:"kb_selection_mode" json:"kb_selection_mode,omitempty"`
}

AgentTypePresetConfig is a restricted view of CustomAgentConfig used purely as the preset payload. Any field left at its zero value is NOT applied by the preset so the user's existing value stays untouched.

We mirror json tags (not yaml tags) directly from CustomAgentConfig so the frontend can apply them via simple Object.assign.

type AgentTypePresetEntry 

type AgentTypePresetEntry struct {
	ID       string                         `yaml:"id"        json:"id"`
	I18n     map[string]AgentTypePresetI18n `yaml:"i18n"      json:"i18n"`
	Config   *AgentTypePresetConfig         `yaml:"config"    json:"config,omitempty"`
	KBFilter *AgentTypeKBFilter             `yaml:"kb_filter" json:"kb_filter,omitempty"`
}

AgentTypePresetEntry is one entry in the agent_type_presets list in YAML.

Only fields relevant for auto-filling the editor form are included under `config`. Everything else (retrieval thresholds, etc.) falls back to the user-edited defaults / CustomAgent.EnsureDefaults.

func GetAgentTypePreset 

func GetAgentTypePreset(id string) *AgentTypePresetEntry

GetAgentTypePreset returns the raw entry for the given preset ID, or nil. Used by prompt-resolution at startup.

func ListAgentTypePresetsWithContext 

func ListAgentTypePresetsWithContext(ctx context.Context) []AgentTypePresetEntry

ListAgentTypePresetsWithContext returns all registered agent-type presets in their YAML-declared order, with i18n resolved against the request locale.

The returned slice is a fresh copy safe to mutate by the caller (e.g. to tweak the i18n label before encoding).

type AgentTypePresetI18n 

type AgentTypePresetI18n struct {
	Label       string `yaml:"label"       json:"label"`
	Description string `yaml:"description" json:"description"`
}

AgentTypePresetI18n holds localised label and description for a single locale.

type AnswerStrategy 

type AnswerStrategy string

AnswerStrategy 定义答案返回策略 

const (
	// AnswerStrategyAll 返回所有答案
	AnswerStrategyAll AnswerStrategy = "all"
	// AnswerStrategyRandom 随机返回一个答案
	AnswerStrategyRandom AnswerStrategy = "random"
)

func NormalizeAnswerStrategy 

func NormalizeAnswerStrategy(s AnswerStrategy) AnswerStrategy

NormalizeAnswerStrategy treats empty as "all".

type ArtifactBlobRef 

type ArtifactBlobRef struct {
	URL        string
	MessageIDs []string
}

ArtifactBlobRef is one stored object the delete orphaned. The caller resolves the owning tenant's file service and releases the resource binding before removing the bytes, so a blob another message or knowledge entry still claims survives.

MessageIDs is every deleted message that owned this object: a later answer that re-attaches an earlier file stores its own row and its own binding, so one delete can retire several claims on the same bytes and all of them have to be released before the object counts as unreferenced.

type ArtifactDeleteRequest 

type ArtifactDeleteRequest struct {
	SessionID string
	MessageID string
	Index     int
	// AllVersions extends the delete to every regeneration of the same sandbox
	// file in this session. The artifact library shows one row per file with a
	// version count, so deleting from there sets this; the in-chat panel lists
	// each version separately and leaves it false.
	AllVersions bool
}

ArtifactDeleteRequest addresses the artifact a user asked to delete. SessionID/MessageID/Index are the same coordinates the download endpoint takes, so a client deletes exactly what it was showing.

type ArtifactDeleteResult 

type ArtifactDeleteResult struct {
	// FileName of the artifact the request addressed, for the response body.
	FileName string
	// Deleted counts the rows this call tombstoned. Zero means another caller
	// got there first; the blobs are then theirs to reclaim, not ours.
	Deleted int
	// Reclaim lists the distinct blobs whose bytes may now be removed.
	Reclaim []ArtifactBlobRef
}

ArtifactDeleteResult reports what a delete tombstoned.

type ArtifactLibraryItem 

type ArtifactLibraryItem struct {
	SessionID    string    `json:"session_id"    gorm:"column:session_id" extensions:"x-agent"`
	SessionTitle string    `json:"session_title" gorm:"column:session_title" extensions:"x-agent"`
	MessageID    string    `json:"message_id"    gorm:"column:message_id" extensions:"x-agent"`
	Index        int       `json:"index"         gorm:"column:position" extensions:"x-agent"`
	URL          string    `json:"-"             gorm:"column:url"`
	Handle       string    `json:"handle,omitempty" gorm:"-" extensions:"x-agent"`
	FileName     string    `json:"file_name"     gorm:"column:file_name" extensions:"x-agent"`
	FileType     string    `json:"file_type"     gorm:"column:file_type" extensions:"x-agent"`
	FileSize     int64     `json:"file_size"     gorm:"column:file_size" extensions:"x-agent"`
	SourcePath   string    `json:"source_path"   gorm:"column:source_path"`
	CreatedAt    time.Time `json:"created_at"    gorm:"column:created_at" extensions:"x-agent"`
	VersionCount int       `json:"version_count" gorm:"column:version_count" extensions:"x-agent"`
}

ArtifactLibraryItem is the latest version of one file in one session. Versions are the artifacts that share a session and sandbox source path: regenerating report.pptx three times is one item with VersionCount 3.

type ArtifactLibraryQuery 

type ArtifactLibraryQuery struct {
	TenantID uint64
	UserID   string
	// Keyword matches the file name, case-insensitively.
	Keyword string
	// FileTypes restricts results to these extensions (".pdf", ".pptx", ...).
	FileTypes []string
	Page      int
	PageSize  int
}

ArtifactLibraryQuery lists the artifacts across every session the caller can see. TenantID and UserID are filled by the service from the request context.

type ArtifactRef 

type ArtifactRef struct {
	MessageID string
	Position  int
}

ArtifactRef addresses one artifact row by its business key. The primary key is not usable for this: writeMessageArtifacts rewrites a message's rows with fresh UUIDs whenever the message is updated, while (message, position) is stable for the life of the artifact.

type AskUserField added in v0.9.0 

type AskUserField struct {
	Name     string   `json:"name"`
	Label    string   `json:"label,omitempty"`
	Type     string   `json:"type"`

	Text     string         `json:"text,omitempty"`
	Declined bool           `json:"declined,omitempty"`
}

AskUserPromptResponse is the Response of an AgentPromptKindAskUser. Declined means the user chose not to answer.

type AssistantAccessLevel added in v0.9.0 

type AssistantAccessLevel string

AssistantAccessLevel is how far the WeKnora assistant may act on the caller's behalf. It only narrows what the caller's role already allows. 

const (
	// AssistantAccessReadOnly offers no operation that changes anything.
	AssistantAccessReadOnly AssistantAccessLevel = "read_only"
	// AssistantAccessConfirm asks the user before every change. It is the
	// level when neither the caller nor the workspace chose one.
	AssistantAccessConfirm AssistantAccessLevel = "confirm"
	// AssistantAccessAutoWrite runs recoverable changes without asking; a
	// destructive change still asks.
	AssistantAccessAutoWrite AssistantAccessLevel = "auto_write"
)

func AccessLevelFromContext added in v0.9.0 

func AccessLevelFromContext(ctx context.Context) AssistantAccessLevel

AccessLevelFromContext is the run's access level. A context that never set one gets AssistantAccessAutoWrite, the level of an agent with no configured ceiling.

func CapAccessLevel added in v0.9.0 

func CapAccessLevel(requested, ceiling AssistantAccessLevel) AssistantAccessLevel

CapAccessLevel is the level a run of an agent whose ceiling is ceiling gets for the requested level. An unset or unknown ceiling is auto_write; an unset or unknown request gets the ceiling.

func (AssistantAccessLevel) Valid added in v0.9.0 

func (l AssistantAccessLevel) Valid() bool

Valid reports whether l is a known level.

type AssistantConfig added in v0.9.0 

type AssistantConfig struct {
	// DisplayName replaces the product name in the assistant UI; empty keeps
	// the default.
	DisplayName string `json:"display_name"`
	// MaxAccessLevel is the highest level a member may pick; empty means
	// AssistantAccessConfirm.
	MaxAccessLevel AssistantAccessLevel `json:"max_access_level"`
}

AssistantConfig is the workspace's assistant setting, stored as JSONB on the tenant.

func (*AssistantConfig) EffectiveAccessLevel added in v0.9.0 

func (c *AssistantConfig) EffectiveAccessLevel(requested AssistantAccessLevel) AssistantAccessLevel

EffectiveAccessLevel is the level a run gets for the requested one: the default when unset or unknown, never above the workspace ceiling. A nil config caps at the default.

func (*AssistantConfig) Normalize added in v0.9.0 

func (c *AssistantConfig) Normalize()

Normalize trims the name and resets an unknown ceiling to the default.

func (*AssistantConfig) Scan added in v0.9.0 

func (c *AssistantConfig) Scan(value interface{}) error

Scan implements sql.Scanner for JSON storage.

func (AssistantConfig) Value added in v0.9.0 

func (c AssistantConfig) Value() (driver.Value, error)

Value implements driver.Valuer for JSON storage.

type AttrInject added in v0.9.0 

type AttrInject string

AttrInject is how an attribute enters the describe prompt. 

const (
	// AttrInjectAlways puts the attribute in every describe round. This is for
	// attributes the pipeline's policy itself reads (contain.text,
	// contain.data_visual): their answers decide whether OCR runs, so they must
	// always be present.
	AttrInjectAlways AttrInject = "always"
	// AttrInjectOnDemand asks the attribute only when a consumer is going to
	// act on it. Asking is not free — it lengthens the prompt and gives the
	// model one more chance to drift — so an attribute whose only job is to
	// gate a later step is asked exactly when that step is switched on, and
	// left out entirely otherwise.
	AttrInjectOnDemand AttrInject = "on_demand"
)

type AttrObservation 

type AttrObservation struct {
	Attrs       ImageAttrs
	Description string
	// Observed reports whether the model returned at least one well-formed
	// attribute line with a usable value. When false no attribute was observed
	// at all and the observation round effectively produced nothing — the
	// caller mirrors this into the trace (observation_failed) so a prompt that
	// derailed the attribute protocol is visible instead of passing for a
	// confident read. It is a runtime signal only and is never persisted: only
	// Attrs is stored with the chunk.
	Observed bool
}

AttrObservation is a parsed observe-and-describe answer: the observed attributes and the description written for the image.

func ParseImageAttrsResponse 

func ParseImageAttrsResponse(raw string) (AttrObservation, bool)

ParseImageAttrsResponse splits an observe-and-describe answer into its attribute lines and its DESCRIPTION. The boolean reports whether the answer yielded a description worth storing; false means the image ends up with attributes but no caption, which the caller records so the missing caption is not read as an observation failure.

Only a reply with no text at all, or one that is nothing but attribute lines, yields false. Prose that skips the labels is kept as the description: the model answered the question, it just did not format the answer.

An attribute the answer does not spell out — because the model skipped the line, or because the value it wrote is not one of the allowed ones — is simply absent from Attrs. Nothing is invented in its place: writing a conservative default there would make an unanswered question look like a confident "block", and would leave the ocr_on_unobserved setting unreachable. The absence is what DecideOCR turns into the conservative decision instead.

type AttrSpec 

type AttrSpec struct {
	Name        string      `json:"name"`                  // stable key, e.g. "contain.text"
	Type        AttrType    `json:"type"`                  // extent | presence
	Values      []AttrValue `json:"values,omitempty"`      // ordered low->high for extent attrs
	Question    string      `json:"question"`              // sentence shown to the model in the describe round
	Label       string      `json:"label"`                 // human-readable name for the settings panel
	Description string      `json:"description,omitempty"` // one line explaining what the attribute measures
	Consumers   []string    `json:"consumers,omitempty"`   // downstream steps that read this attribute
	// Internal marks an attribute that steers this pipeline's own scheduling
	// rather than describing what the image holds. Such attributes are still
	// observed and persisted — the values are what justify a scheduling
	// decision after the fact — but they are kept out of the gallery's filter
	// surface, where they would only add noise: no operator wants to filter a
	// library by "how much margin is left around the text".
	Internal bool `json:"internal,omitempty"`
	// Inject says whether this attribute is always part of the describe round's
	// standing questions, or only asked when something is going to act on it.
	// An empty value means AttrInjectAlways, so attributes registered before
	// this field existed keep their behaviour.
	Inject AttrInject `json:"inject,omitempty"`
}

AttrSpec is one observable image attribute. The registry is the single source of truth for which attributes exist this release; adding an attribute is one line here plus a decision clause, and never a struct change elsewhere. That is what makes "add an attribute = add a row" a real, low-risk operation. The same row also carries the attribute's display text. The settings panel that explains the attributes to a non-technical operator is rendered from these fields, so adding an attribute needs no frontend change either: Label, Description and the per-value texts travel to the UI through the schema endpoint. An attribute is always accompanied by a short label for compact spaces and a sentence for places with room.

func (AttrSpec) WantsInjection added in v0.9.0 

func (s AttrSpec) WantsInjection(onDemandConsumersActive bool) bool

WantsInjection reports whether this attribute belongs in a describe round that is being built for the given situation. onDemandOnly callers (a step that has nothing to act on) skip the on-demand attributes entirely.

type AttrType 

type AttrType string

AttrType is the shape of an observed attribute value. 

const (
	// AttrTypeExtent is an ordered set of values, e.g. none < sparse < block.
	AttrTypeExtent AttrType = "extent"
	// AttrTypePresence is a boolean observation, e.g. true / false.
	AttrTypePresence AttrType = "presence"
)

type AttrValue 

type AttrValue struct {
	Value       string `json:"value"`                 // raw machine value, never localized
	Label       string `json:"label"`                 // short on-screen name
	Description string `json:"description,omitempty"` // sentence explaining the value
}

AttrValue is one allowed value of an attribute: the raw value plus the words to show for it.

Display text is split in two on purpose. Label is the short name that fits on a filter checkbox or a table cell; Description is the sentence that explains the value where there is room (a tooltip, the settings panel). Both are written in the project's default language; the frontend overlays its translations on top (see imageAttrDisplay in the web app) and falls back to these strings for anything not translated yet.

type AuditAPIKey 

type AuditAPIKey struct {
	ID   uint64
	Name string
}

AuditAPIKey is the display identity of the API key that initiated work. It is not an authorization grant and must not be confused with TenantAPIKeyScope.

func AuditAPIKeyFromContext 

func AuditAPIKeyFromContext(ctx context.Context) (AuditAPIKey, bool)

type AuditAction 

type AuditAction string

AuditAction names a single audited action class. Action constants are dot-namespaced (`<area>.<event>`) so future PRs can plug in their own areas (e.g. `kb.shared`, `agent.copied`) without colliding with the RBAC events PR 6 ships. 

const (
	// AuditActionMemberAdded fires when a tenant Owner / Admin adds a
	// new tenant_members row. The actor is the inviter; the target is
	// the invited user.
	AuditActionMemberAdded AuditAction = "rbac.member_added"
	// AuditActionMemberRemoved fires when an Owner / Admin removes a
	// tenant_members row. Distinct from MemberLeft so an audit reader
	// can tell "kicked out" from "left voluntarily".
	AuditActionMemberRemoved AuditAction = "rbac.member_removed"
	// AuditActionMemberRoleChanged fires for promote/demote operations.
	// The Details payload carries old_role and new_role.
	AuditActionMemberRoleChanged AuditAction = "rbac.member_role_changed"
	// AuditActionMemberLeft fires on POST /tenants/:id/leave — the
	// actor and target are the same user.
	AuditActionMemberLeft AuditAction = "rbac.member_left"
	// AuditActionAccessDenied fires when middleware/rbac.go's
	// RequireRole or RequireOwnershipOrRole rejects a request under
	// EnableRBAC=true. Subject to 1-minute sliding-window dedup so a
	// probing client cannot fill the table.
	AuditActionAccessDenied AuditAction = "rbac.access_denied"
	// AuditActionInvitationSent fires when an Owner issues a new
	// tenant invitation. Actor is the inviter, TargetUserID is the
	// invitee. Note: AuditActionMemberAdded only fires when the
	// invitee actually accepts and the tenant_members row is created.
	AuditActionInvitationSent AuditAction = "rbac.invitation_sent"
	// AuditActionInvitationAccepted fires when the invitee accepts a
	// pending invitation. Actor is the invitee (acting on their own
	// inbox); the matching rbac.member_added is emitted in the same
	// transaction.
	AuditActionInvitationAccepted AuditAction = "rbac.invitation_accepted"
	// AuditActionInvitationDeclined fires when the invitee rejects a
	// pending invitation. Actor and target are the same user.
	AuditActionInvitationDeclined AuditAction = "rbac.invitation_declined"
	// AuditActionInvitationRevoked fires when a tenant Owner cancels
	// a still-pending invitation before the invitee acts. Actor is
	// the Owner; target is the invitee.
	AuditActionInvitationRevoked AuditAction = "rbac.invitation_revoked"
	// AuditActionInvitationExpired fires when the lazy sweep transitions
	// an overdue pending row to expired. Actor is empty (system).
	AuditActionInvitationExpired AuditAction = "rbac.invitation_expired"

	// AuditActionVectorStoreCreated fires when a new VectorStore row
	// is committed to the DB (Phase 1 CRUD path). Actor is the tenant
	// user; resource is the VectorStore.
	AuditActionVectorStoreCreated AuditAction = "vector_store.created"
	// AuditActionVectorStoreUpdated fires on UPDATE of any VectorStore
	// mutable field. Details payload carries the changed key set
	// (never the secret values themselves — only the field names).
	AuditActionVectorStoreUpdated AuditAction = "vector_store.updated"
	// AuditActionVectorStoreDeleted fires when a VectorStore is
	// (soft-)deleted. Phase 2's delete guard already prevents deletion
	// of stores with bound KBs; the audit row records the actor and
	// the store_id for forensic traceability.
	AuditActionVectorStoreDeleted AuditAction = "vector_store.deleted"

	// AuditActionOpenSearchIndexCreated fires when the OpenSearch
	// driver lazily creates a per-dimension index (the first time a
	// KB with a given embedding dim binds to the store). Details
	// payload: index name, alias name, dimension.
	AuditActionOpenSearchIndexCreated AuditAction = "opensearch.index_created"

type AuditAgentAction added in v0.9.0 

type AuditAgentAction struct {
	SessionID string `json:"session_id,omitempty"`
	AgentID   string `json:"agent_id,omitempty"`
	Operation string `json:"operation,omitempty"`
	// ActingVia is the principal's ActingVia when the agent ran on its own,
	// e.g. "automation:<id>".
	ActingVia string `json:"acting_via,omitempty"`
}

AuditAgentAction attributes a mutation to an agent acting for the signed-in user. It is display metadata for the activity feed, never an authorization grant: the mutation itself is authorized as the user.

func AuditAgentActionFromContext added in v0.9.0 

func AuditAgentActionFromContext(ctx context.Context) (AuditAgentAction, bool)

AuditAgentActionFromContext returns the agent action attached to ctx.

type AuditLog 

type AuditLog struct {
	ID            uint64       `` /* 143-byte string literal not displayed */
	TenantID      uint64       `` /* 180-byte string literal not displayed */

	CreatedAt     time.Time    `json:"created_at"     gorm:"index:idx_audit_logs_tenant_id_desc,priority:2,sort:desc" extensions:"x-agent"`
}

AuditLog is a single immutable audit event. The schema is intentionally generic: PR 6 wires only RBAC events, but TargetType / TargetID / Details are set up to absorb KB / agent / datasource events in follow-up PRs without another migration. Knowledge-base task events use a bounded convention inside Details: task_id, trigger, processing_status, source/target ids, aggregate counts, and operation-specific mode/attempt.

Rows are append-only — no UpdatedAt, no soft-delete column. The monotonic ID acts as both primary key and pagination cursor (newest- first is `WHERE id < AfterID ORDER BY id DESC`).

func (AuditLog) TableName 

func (AuditLog) TableName() string

TableName pins the table name even if a future GORM convention pluralisation refactor would otherwise rename it.

type AuditOutcome 

type AuditOutcome string

AuditOutcome separates asynchronous acceptance from terminal business results and middleware-level rejections. The UI can therefore avoid presenting a queued operation as already completed. 

const (
	AuditOutcomeSuccess AuditOutcome = "success"
	// Accepted means the durable request was created and asynchronous work was
	// submitted, but the background operation has not reached a terminal state.
	AuditOutcomeAccepted AuditOutcome = "accepted"
	AuditOutcomeDenied   AuditOutcome = "denied"
	AuditOutcomeFailed   AuditOutcome = "failed"
	AuditOutcomePartial  AuditOutcome = "partial"
	AuditOutcomeCanceled AuditOutcome = "canceled"
)

type AuthToken 

type AuthToken struct {
	// Unique identifier of the token
	ID string `json:"id"         gorm:"type:varchar(36);primaryKey"`
	// User ID that owns this token
	UserID string `json:"user_id"    gorm:"type:varchar(36);index;not null"`
	// Token value (JWT or other format)
	Token string `json:"token"      gorm:"type:text;not null"`
	// Token type (access_token, refresh_token)
	TokenType string `json:"token_type" gorm:"type:varchar(50);not null"`
	// Token expiration time
	ExpiresAt time.Time `json:"expires_at"`
	// Whether the token is revoked
	IsRevoked bool `json:"is_revoked" gorm:"default:false"`
	// Creation time of the token
	CreatedAt time.Time `json:"created_at"`
	// Last updated time of the token
	UpdatedAt time.Time `json:"updated_at"`

	// Association relationship
	User *User `json:"user,omitempty" gorm:"foreignKey:UserID"`
}

AuthToken represents an authentication token

type AutoTagConfig 

type AutoTagConfig struct {
	// Enabled turns automatic tagging on. The model picks from tags that already exist.
	Enabled bool `yaml:"enabled" json:"enabled" extensions:"x-agent=auto_tag_enabled"`
	// ModelID overrides the summary model. Empty uses summary_model_id.
	ModelID string `yaml:"model_id,omitempty" json:"model_id,omitempty" extensions:"x-agent=auto_tag_model_id"`
	// MaxTags is how many tags one document may receive, from 1 to 10.
	MaxTags int `yaml:"max_tags,omitempty" json:"max_tags,omitempty" minimum:"1" maximum:"10" extensions:"x-agent=auto_tag_max_tags"`
	// SkipIfTagged leaves a document alone when it already has tags. Empty means yes.
	SkipIfTagged *bool `yaml:"skip_if_tagged,omitempty" json:"skip_if_tagged,omitempty" extensions:"x-agent=auto_tag_skip_if_tagged"`
}

AutoTagConfig controls asynchronous document auto-tagging. It is deliberately opt-in so upgrading an existing deployment does not add model calls or alter document tags unexpectedly.

func (*AutoTagConfig) Normalize 

func (c *AutoTagConfig) Normalize()

Normalize applies defaults and bounds to the automatic-tagging configuration.

func (*AutoTagConfig) Scan 

func (c *AutoTagConfig) Scan(value interface{}) error

Scan deserializes the automatic-tagging configuration from a database value.

func (*AutoTagConfig) ShouldSkipIfTagged 

func (c *AutoTagConfig) ShouldSkipIfTagged() bool

ShouldSkipIfTagged reports whether documents with existing tags are left alone. Defaults to true for nil receivers and unset values.

func (AutoTagConfig) Value 

func (c AutoTagConfig) Value() (driver.Value, error)

Value serializes the automatic-tagging configuration for database storage.

AutomationBinding is what an automation's grants were given under. A grant stops applying once any of it changes: the agent's tools, MCP services or instructions, the owner's workspace role, or the agent's access ceiling.

func (AutomationBinding) Hash added in v0.9.0 

func (b AutomationBinding) Hash() string

Hash is the binding as stored in AgentGrant.BindingHash. Tool and service order does not matter.

type AutomationLimits added in v0.9.0

type ChatHistoryConfig 

type ChatHistoryConfig struct {
	// Enabled controls whether chat history indexing is active
	Enabled bool `json:"enabled"`
	// EmbeddingModelID is the ID of the embedding model used for vectorizing chat messages.
	// Once messages have been indexed, the model cannot be changed (requires re-indexing).
	EmbeddingModelID string `json:"embedding_model_id"`
	// KnowledgeBaseID is the auto-managed hidden knowledge base for chat history.
	// This is set internally when the feature is first enabled; users should not set this directly.
	KnowledgeBaseID string `json:"knowledge_base_id"`
}

ChatHistoryConfig represents the chat history knowledge base configuration for a tenant. This config is managed via the settings UI and controls how chat messages are indexed and searched using a knowledge base for vector search.

The KnowledgeBaseID is auto-managed: when the user enables the feature and picks an embedding model, the backend automatically creates (or reuses) a hidden KB. Users do NOT pick a KB themselves.

func (*ChatHistoryConfig) IsConfigured 

func (c *ChatHistoryConfig) IsConfigured() bool

IsConfigured returns true if the chat history KB is properly configured and ready to use. Requires: enabled + embedding model selected + KB auto-created.

func (*ChatHistoryConfig) Scan 

func (c *ChatHistoryConfig) Scan(value interface{}) error

Scan implements the sql.Scanner interface for database deserialization

func (ChatHistoryConfig) Value 

func (c ChatHistoryConfig) Value() (driver.Value, error)

Value implements the driver.Valuer interface for database serialization

type ChatHistoryKBStats 

type ChatHistoryKBStats struct {
	// Whether the chat history KB is configured and enabled
	Enabled bool `json:"enabled" extensions:"x-agent"`
	// ID of the embedding model used
	EmbeddingModelID string `json:"embedding_model_id,omitempty" extensions:"x-agent"`
	// ID of the knowledge base used for chat history
	KnowledgeBaseID string `json:"knowledge_base_id,omitempty"`
	// Name of the knowledge base
	KnowledgeBaseName string `json:"knowledge_base_name,omitempty"`
	// Number of indexed message entries (Knowledge count)
	IndexedMessageCount int64 `json:"indexed_message_count" extensions:"x-agent"`
	// Whether there are any indexed messages (used by frontend to lock embedding model)
	HasIndexedMessages bool `json:"has_indexed_messages"`
}

type ChatManage 

type ChatManage struct {
	PipelineRequest
	PipelineState
	PipelineContext
}

ChatManage represents the full configuration, state and runtime context for a chat pipeline execution. It embeds PipelineRequest (immutable config), PipelineState (mutable intermediate data), and PipelineContext (runtime handles).

func (*ChatManage) Clone 

func (c *ChatManage) Clone() *ChatManage

Clone creates a deep copy of the ChatManage object. PipelineContext fields (EventBus, MessageID, etc.) are NOT copied because they are per-execution handles that should not be shared across clones.

func (*ChatManage) NeedsRetrieval 

func (c *ChatManage) NeedsRetrieval() bool

NeedsRetrieval returns true when the current pipeline execution should run the retrieval stages (search, rerank, merge, etc.). For IntentWebSearch, retrieval is only needed if web search is enabled; otherwise the intent prompt (intent_prompts.yaml "web_search") tells the user web search is unavailable. All other intents delegate to QueryIntent.NeedsKBRetrieval().

func (*ChatManage) RecordRetrievalCut 

func (c *ChatManage) RecordRetrievalCut(stage string, candidates int)

RecordRetrievalCut notes that a ranked-list stage dropped candidate passages before the model context was built. candidates is the population that stage received, read before the cut; it must never be a knowledge-base match count, which retrieval does not compute at this depth.

The first cut wins. Later stages only see an equal or narrower population (FILTER_TOP_K cuts merge output, merge's fallback cuts the search output), so letting them overwrite the record would restate the candidate pool as something smaller than what retrieval produced and hide how much was dropped.

type ChatResponse 

type ChatResponse struct {
	Content string `json:"content"`
	// ReasoningContent 是支持思考链的模型（DeepSeek thinking、小米 MiMo、vLLM reasoning 等）

	// AnswerStreamed reports whether the user-facing answer text was already
	// streamed live to the final-answer UI area during this round (i.e. the
	// model answered with plain content). When true, the natural-stop branch
	// must only emit the closing
	// Done marker for AnswerEventID instead of re-emitting the whole answer —
	// otherwise the answer would render twice and "jump" at end of stream.
	// Transient, never persisted.
	AnswerStreamed bool `json:"-"`
	// AnswerEventID is the EventBus event ID under which the live answer
	// chunks were streamed, so the natural-stop branch can close the same
	// stream with a Done marker. Empty when AnswerStreamed is false.
	AnswerEventID string `json:"-"`
}

	InsecureSkipVerify bool `yaml:"insecure_skip_verify" json:"insecure_skip_verify,omitempty"`
	// Qdrant
	Host   string `yaml:"host" json:"host,omitempty"`

	// Degraded marks a raw archive kept because the summarizer failed. The
	// next compaction folds it in as the previous summary.
	Degraded bool `json:"degraded,omitempty"`
}

ContextCheckpoint is an agent compaction summary persisted on the assistant message of the last turn it covers. The next turn's history starts from the newest checkpoint instead of from the raw turns it replaces, so a compaction is paid for once rather than again on every later turn.

Storing it on the covered turn rather than on the turn that ran the compaction keeps the boundary implicit: a fork that copies the turn copies the checkpoint with it, and deleting the turn drops the checkpoint too.

func (*ContextCheckpoint) Scan 

func (c *ContextCheckpoint) Scan(value any) error

Scan implements the sql.Scanner interface for database deserialization.

func (ContextCheckpoint) Value 

func (c ContextCheckpoint) Value() (driver.Value, error)

Value implements the driver.Valuer interface for database serialization.

type ContextCheckpointSink interface {
	// SaveContextCheckpoint stores checkpoint on the assistant message
	// turnMessageID, replacing any earlier checkpoint there.
	SaveContextCheckpoint(ctx context.Context, turnMessageID string, checkpoint *ContextCheckpoint) error
}

ContextCheckpointSink persists compaction checkpoints for the agent engine. Declared in types for the same reason as SteerSink: the engine and the service both need the shape and neither may import the other.

type ContextCompressionStrategy 

type ContextCompressionStrategy string

ContextCompressionStrategy represents the strategy for context compression 

const (
	// ContextCompressionSlidingWindow keeps the most recent N messages
	ContextCompressionSlidingWindow ContextCompressionStrategy = "sliding_window"
	// ContextCompressionSmart uses LLM to summarize old messages
	ContextCompressionSmart ContextCompressionStrategy = "smart"
)

type ContextConfig 

type ContextConfig struct {
	// Maximum tokens allowed in LLM context
	MaxTokens int `json:"max_tokens"`
	// Compression strategy: "sliding_window" or "smart"
	CompressionStrategy ContextCompressionStrategy `json:"compression_strategy"`
	// For sliding_window: number of messages to keep
	// For smart: number of recent messages to keep uncompressed
	RecentMessageCount int `json:"recent_message_count"`
	// Summarize threshold: number of messages before summarization
	SummarizeThreshold int `json:"summarize_threshold"`
}

ContextConfig configures LLM context management This is separate from message storage and manages token limits

func (*ContextConfig) Scan 

func (c *ContextConfig) Scan(value interface{}) error

Scan implements the sql.Scanner interface, used to convert database value to ContextConfig

func (*ContextConfig) Value 

func (c *ContextConfig) Value() (driver.Value, error)

Value implements the driver.Valuer interface, used to convert ContextConfig to database value

type ContextKey

const MemoryDisabledContextKey ContextKey = "MemoryDisabled"

MemoryDisabledContextKey marks a request whose agent opted out of memory. The agent switch is per-request rather than per-scope, so it travels in the context instead of the database: the same user talking to two agents gets memory in one conversation and not the other.

Exported because logger.CloneContext rebuilds contexts from an allowlist of keys, and the memory write path (extraction, explicit remember, document affinity) runs on the far side of one of those rebuilds. A key left unexported here would be silently dropped there, leaving an opted-out agent unable to read memory while still writing to it.

func ContextKeysClonedAcrossDetach 

func ContextKeysClonedAcrossDetach() []ContextKey

ContextKeysClonedAcrossDetach returns the keys logger.CloneContext carries into a detached context, sorted so the result does not depend on map order.

	SNI     string   `json:"sni,omitempty"`
	Host    string   `json:"host,omitempty"`
	Methods []string `json:"methods,omitempty"`
	Path    string   `json:"path,omitempty"`

	// Deny inverts the action, which defaults to allow. A deny rule still
	// needs Host or SNI: the target has to reach CubeEgress for it to answer
	// with a request-level 403 instead of the network layer dropping it.
	Deny bool `json:"deny,omitempty"`

	// Audit is none | metadata | full. Empty uses the server default.
	Audit string `json:"audit,omitempty"`

	// Inject adds credential headers on allowed HTTPS requests.
	Inject []CubeHeaderInject `json:"inject,omitempty"`
}

CubeEgressRule mirrors cubesandbox.Rule. Match fields are AND-ed; Methods is OR-ed internally.

type CubeHeaderInject 

type CubeHeaderInject struct {
	Header string `json:"header"`
	Secret string `json:"secret"`
	Format string `json:"format,omitempty"`
}

CubeHeaderInject mirrors cubesandbox.Inject. Secret is a credential and is encrypted at rest; Header and Format are not.

type CubeSandboxConfig 

type CubeSandboxConfig struct {

	CubeSandboxTTLSeconds int `json:"cube_sandbox_ttl_seconds,omitempty"`

	// DNSServers are Cube template nameserver IPs. Empty uses Cubelet's default.
	DNSServers []string `json:"dns_servers,omitempty"`
}

CubeSandboxConfig addresses one CubeSandbox deployment. APIURL, ProxyURL, SandboxDomain and TemplateID are all required; APIKey is optional because the common single-node setup runs unauthenticated.

type CustomAgent 

type CustomAgent struct {
	// Unique identifier of the agent (composite primary key with TenantID)
	// For built-in agents, this is 'builtin-quick-answer' or 'builtin-smart-reasoning'

	// 仍可能为空。
	CreatorName string `yaml:"-" json:"creator_name,omitempty" gorm:"-" extensions:"x-agent"`
}

CustomAgent represents a configurable AI agent (similar to GPTs)

func GetBuiltinAgent 

func GetBuiltinAgent(id string, tenantID uint64) *CustomAgent

func (*CustomAgent) EnsureDefaults 

func (a *CustomAgent) EnsureDefaults()

EnsureDefaults sets default values for the agent.

func (*CustomAgent) IsAgentMode 

func (a *CustomAgent) IsAgentMode() bool

IsAgentMode returns true if this agent uses ReAct agent mode

func (CustomAgent) TableName 

func (CustomAgent) TableName() string

TableName returns the table name for CustomAgent

func (*CustomAgent) ValidateAvatar 

func (a *CustomAgent) ValidateAvatar() error

ValidateAvatar rejects an avatar value the DB column cannot store.

Without it, an oversized avatar (a data-URI icon, say) reaches postgres unchecked and comes back as a raw driver error — "ERROR: value too long for type character varying(64) (SQLSTATE 22001)" — which is then forwarded to the client as a 500. That is two problems at once: the caller only learns the real limit from a crash, and internal database details leak into a public API. Checking here turns it into an ordinary 400 that names the limit, like the other request validations.

DataSource represents a configured external data source for synchronization

func (*DataSource) BeforeCreate 

func (d *DataSource) BeforeCreate(tx *gorm.DB) error

BeforeCreate hook to generate UUID

func (*DataSource) ParseConfig 

func (d *DataSource) ParseConfig() (*DataSourceConfig, error)

ParseConfig deserializes DataSource.Config and decrypts any encrypted Credentials entries.

DecryptStoredSecret transparently handles three cases per credential:

  • empty string: untouched
  • legacy plaintext (no enc:v1: prefix): returned as-is, so historical rows continue to work without a migration step
  • enc:v1: encrypted: decrypted with SYSTEM_AES_KEY; missing/rotated key surfaces as an error so we fail loudly rather than handing ciphertext to the upstream connector as the credential

func (*DataSource) ParseSyncCursor 

func (d *DataSource) ParseSyncCursor() (*SyncCursor, error)

ParseSyncCursor parses the cursor JSON

func (*DataSource) ParseSyncResult 

func (d *DataSource) ParseSyncResult() (*SyncResult, error)

ParseSyncResult parses the result JSON

func (*DataSource) TableName 

func (d *DataSource) TableName() string

TableName specifies the table name for DataSource

type DataSourceConfig 

type DataSourceConfig struct {
	// Common fields applicable to most connectors
	Type string `json:"type"`

	// OAuth/API credentials (varies by connector)
	Credentials map[string]interface{} `json:"credentials"`

	// Selected resource IDs to sync (e.g., folder IDs, space IDs)
	ResourceIDs []string `json:"resource_ids"`

	// Connector-specific configuration
	Settings map[string]interface{} `json:"settings"`
}

DataSourceConfig represents the unencrypted configuration structure Each connector type will have its own specific fields.

Credential management lives in the dedicated /credentials subresource (see internal/handler/datasource_credentials.go). Secret values are never included in API responses — handlers serialize via dto.NewDataSourceResponse which strips the Credentials map by construction.

func (DataSourceConfig) HasConfiguredCredentials 

func (d DataSourceConfig) HasConfiguredCredentials(connectorType string) bool

HasConfiguredCredentials reports whether user-facing secret credentials are stored. RSS feed URLs are non-secret configuration (settings); only auth_headers count as credentials for that connector.

func (DataSourceConfig) HasCredentials 

func (d DataSourceConfig) HasCredentials() bool

HasCredentials reports whether the credentials map carries any value at all. Used by the Update path and by the credential subresource to decide whether to run live-connector validation.

func (*DataSourceConfig) StripNonSecretCredentials 

func (d *DataSourceConfig) StripNonSecretCredentials(connectorType string)

StripNonSecretCredentials removes non-secret values mistakenly stored in the credentials map before persistence.

func (*DataSourceConfig) ToJSON 

func (d *DataSourceConfig) ToJSON() (JSON, error)

ToJSON converts a DataSourceConfig to the JSON blob stored in DataSource.Config.

When SYSTEM_AES_KEY is configured, every string value inside Credentials is AES-256-GCM encrypted before serialization. Non-string values (numbers, bools, nested objects) pass through untouched. This is the only write path through which credentials reach the DB (the GORM JSON type itself is a byte passthrough), so encrypting here is sufficient to keep DataSource.Config at rest fully encrypted.

Encryption operates on a shallow copy of Credentials to avoid mutating the caller's in-memory map (subsequent reads would otherwise see ciphertext).

type DataSourceSyncPayload 

type DataSourceSyncPayload struct {
	TracingContext
	Initiator TaskInitiator `json:"initiator,omitempty"`
	// Trigger distinguishes a user-requested run from a scheduler-created run.
	Trigger string `json:"trigger,omitempty"`

	// Data source ID to sync
	DataSourceID string `json:"data_source_id"`

	// Workspace ID
	TenantID uint64 `json:"tenant_id"`

	// Sync log ID (for tracking)
	SyncLogID string `json:"sync_log_id"`

	// Force full sync even if incremental mode is configured
	ForceFull bool `json:"force_full"`

	// Maximum number of items to fetch (0 = unlimited)
	MaxItems int `json:"max_items,omitempty"`
}

DataSourceSyncPayload represents the asynq task payload for data source sync

type DefaultSettings added in v0.9.0 

type DefaultSettings struct {
	// ChatModelID is the default KnowledgeQA model.
	ChatModelID string `json:"chat_model_id"`
	// UtilityModelID is the KnowledgeQA model for short generation tasks
	// such as writing MCP usage instructions. Empty follows the chat default.
	UtilityModelID string `json:"utility_model_id"`
	// EmbeddingModelID is the default Embedding model.
	EmbeddingModelID string `json:"embedding_model_id"`
	// RerankModelID is the default Rerank model.
	RerankModelID string `json:"rerank_model_id"`
	// VLMModelID is the default VLLM or vision-capable KnowledgeQA model.
	VLMModelID string `json:"vlm_model_id"`
	// ASRModelID is the default ASR model.
	ASRModelID string `json:"asr_model_id"`
}

DefaultSettings is the workspace's choice of default models, stored as JSONB on the tenant. An empty field leaves the slot to the deployment's default (the is_default flag a built-in model YAML sets).

The default web search provider is not stored here: providers carry their own is_default flag, which the provider page already edits.

func (*DefaultSettings) ApplyModelDefaults added in v0.9.0 

func (c *DefaultSettings) ApplyModelDefaults(models []*Model)

ApplyModelDefaults projects workspace defaults onto a fresh model list. IsDefault remains specific to the model's native type. DefaultFor also represents cross-type vision choices and the utility purpose. Missing or inactive choices leave deployment defaults in effect.

func (*DefaultSettings) ModelSlots added in v0.9.0 

func (c *DefaultSettings) ModelSlots() map[ModelType]string

ModelSlots maps each model-type slot to the capability its model must support. The utility slot is a KnowledgeQA model chosen for a purpose rather than a type, so it is listed separately by callers that validate it.

func (*DefaultSettings) Normalize added in v0.9.0 

func (c *DefaultSettings) Normalize()

Normalize trims every ID.

func (*DefaultSettings) Scan added in v0.9.0 

func (c *DefaultSettings) Scan(value interface{}) error

Scan implements sql.Scanner for JSON storage.

func (DefaultSettings) Value added in v0.9.0 

func (c DefaultSettings) Value() (driver.Value, error)

Value implements driver.Valuer for JSON storage.

type DocParserStorageConfig 

type DocParserStorageConfig struct {
	Provider        string
	Region          string
	BucketName      string
	AccessKeyID     string
	SecretAccessKey string
	AppID           string
	PathPrefix      string
	Endpoint        string
}

type DocParserVLMConfig 

type DocParserVLMConfig struct {
	ModelName     string
	BaseURL       string
	APIKey        string
	InterfaceType string
}

type DockerSandboxConfig 

type DockerSandboxConfig struct {
	Image string `json:"image,omitempty"`

	// Host is the daemon endpoint in DOCKER_HOST form. Empty means the local
	// unix socket.
	Host string `json:"host,omitempty"`

	// TLSCertPath is a directory on the WeKnora host containing ca.pem,
	// cert.pem and key.pem. Required when Host is a TCP endpoint.
	TLSCertPath string `json:"tls_cert_path,omitempty"`

	// CPULimit is the number of CPU cores one sandbox may use. 0 uses the
	// built-in default.
	CPULimit float64 `json:"cpu_limit,omitempty"`

	// MemoryLimitMB caps one sandbox's memory. 0 uses the built-in default.
	MemoryLimitMB int `json:"memory_limit_mb,omitempty"`

	// PidsLimit caps how many processes one sandbox may run. 0 uses the
	// built-in default.
	PidsLimit int `json:"pids_limit,omitempty"`

	// NetworkMode is the Docker network sandboxes join: "bridge" (default) or
	// "none" for no egress. Nothing else is accepted — host and container:
	// modes share another namespace outright, and a named network is usually
	// the deployment's own compose network, which would put the sandbox next
	// to Postgres and Redis.
	NetworkMode string `json:"network_mode,omitempty"`

	// Runtime selects an alternative OCI runtime such as "runsc" (gVisor).
	// Empty uses the daemon default.
	Runtime string `json:"runtime,omitempty"`

	// IdleTTLSeconds is how long a session container may go unused before it
	// is reclaimed. The daemon has no idle timeout of its own, so this is what
	// stops an abandoned session from pinning host memory indefinitely.
	IdleTTLSeconds int `json:"idle_ttl_seconds,omitempty"`

	// HTTPTimeoutSec bounds each Engine API call. 0 uses the built-in default.
	HTTPTimeoutSec int `json:"http_timeout_sec,omitempty"`
}

DockerSandboxConfig addresses one Docker daemon. Image is required and plays the role a template ID plays for the MicroVM backends: every session container is created from it.

The daemon endpoint is deliberately the only connection field, and TLS material is referenced by path rather than stored here. Client certificates are deployment infrastructure mounted onto the WeKnora host; keeping them out of the database keeps them out of backups, exports and API responses.

type DocumentChunkMetadata 

type DocumentChunkMetadata struct {
	// GeneratedQuestions 存储AI为该Chunk生成的相关问题
	// 这些问题会被独立索引以提高召回率
	GeneratedQuestions []GeneratedQuestion `json:"generated_questions,omitempty"`
	// GeneratedQuestionsRevision ties the questions to Chunk.ContentRevision.
	GeneratedQuestionsRevision int `json:"generated_questions_revision,omitempty"`
}

DocumentChunkMetadata 定义文档 Chunk 的元数据结构 用于存储AI生成的问题等增强信息

func (*DocumentChunkMetadata) GetQuestionStrings 

func (m *DocumentChunkMetadata) GetQuestionStrings() []string

GetQuestionStrings 返回问题内容字符串列表（兼容旧代码）

func (*DocumentChunkMetadata) IsQuestionCurrent 

func (m *DocumentChunkMetadata) IsQuestionCurrent(question GeneratedQuestion, chunkRevision int) bool

IsQuestionCurrent reports whether a generated question was authored for the current chunk body. This is advisory metadata for the UI: questions remain valid retrieval aliases across chunk edits. Legacy rows fall back to the metadata-level revision.

type DocumentProcessPayload 

type DocumentProcessPayload struct {
	TracingContext
	RequestId                string   `json:"request_id"`
	TenantID                 uint64   `json:"tenant_id"`

	Passages                 []string `json:"passages,omitempty"`  // 文本段落（文本导入时使用）
	EnableMultimodel         bool     `json:"enable_multimodel"`
	EnableQuestionGeneration bool     `json:"enable_question_generation"` // 是否启用问题生成
	QuestionCount            int      `json:"question_count,omitempty"`   // 每个chunk生成的问题数量
	Language                 string   `json:"language,omitempty"`         // Request locale for {{language}} in prompt templates
	// Attempt is the per-knowledge attempt number this task belongs to.
	// Set on enqueue (initial parse → attempt 1; reparse → max+1) so
	// every span recorded by this task lands on the right attempt
	// branch. Asynq retries within an attempt keep the same value so
	// retried spans overwrite the previous attempt's row rather than
	// fan out into a new attempt for every retry.
	Attempt int `json:"attempt,omitempty"`
}

DocumentProcessPayload represents the document process task payload

type DuplicateKnowledgeError 

type DuplicateKnowledgeError struct {
	Message   string
	Knowledge *Knowledge
}

DuplicateKnowledgeError duplicate knowledge error, contains the existing knowledge object

func NewDuplicateFileError 

func NewDuplicateFileError(knowledge *Knowledge) *DuplicateKnowledgeError

NewDuplicateFileError creates a duplicate file error

func NewDuplicateURLError 

func NewDuplicateURLError(knowledge *Knowledge) *DuplicateKnowledgeError

NewDuplicateURLError creates a duplicate URL error

func (*DuplicateKnowledgeError) Error 

func (e *DuplicateKnowledgeError) Error() string

type E2BHostRule 

type E2BHostRule struct {
	Host string `json:"host"`
	// Headers values are credentials and are encrypted at rest; names stay
	// readable so operators can see which headers are injected.
	Headers map[string]string `json:"headers,omitempty"`
}

E2BHostRule mirrors one entry of e2b.NetworkConfig.Rules. Host must also appear in AllowOut: a rule grants no egress on its own.

type E2BSandboxConfig 

type E2BSandboxConfig struct {
	APIURL        string `json:"api_url,omitempty"`
	SandboxDomain string `json:"sandbox_domain,omitempty"`
	APIKey        string `json:"api_key,omitempty"` // 加密
	TemplateID    string `json:"template_id,omitempty"`

	// ProxyURL is the data-plane gateway that fronts envd. E2B Cloud resolves
	// "<port>-<sandboxID>.<sandbox_domain>" through public DNS and TLS, so it
	// needs no value here. Self-hosted E2B-compatible control planes usually
	// serve every sandbox from one gateway address and expect the sandbox
	// authority in the Host header; setting this makes WeKnora dial the
	// gateway directly instead of requiring wildcard DNS and a certificate
	// for the sandbox domain. An "http://" gateway also downgrades the
	// data-plane scheme, which the E2B SDK otherwise pins to https.
	ProxyURL string `json:"proxy_url,omitempty"`

	// HTTPTimeoutSec bounds each HTTP call to the sandbox control plane.
	// 0 means use the built-in default (30s), never the deployment's value.
	HTTPTimeoutSec int `json:"http_timeout_sec,omitempty"`

	E2BSandboxTTLSeconds int `json:"e2b_sandbox_ttl_seconds,omitempty"`
}

E2BSandboxConfig addresses one E2B-protocol control plane: E2B Cloud, a self-hosted E2B Infrastructure, or any E2B-compatible implementation (CubeSandbox, Agent-Sandbox, …). APIKey and TemplateID are required; APIURL and SandboxDomain are optional because go-e2b resolves both on its own when they are empty.

type EffectiveProcessConfig struct {
	SummaryEnabled           bool
	ChunkingConfig           ChunkingConfig
	EnableMultimodel         bool

	ImageAttrsEnabled        bool
	ImageVectorEnabled       bool
	ImageActions             ImageActionsConfig
	ImagePipelineID          ImagePipelineID
	// ImagePipelineParams carries every setting that pipeline declares, each
	// under that pipeline's slot — including the ones this layer needs to read
	// (the page-straightening mode, the OCR fallback clause). There is no second
	// copy of them above: a run reads this map for them, and the trace echoes
	// the same map, so what ran and what was recorded cannot disagree.
	ImagePipelineParams map[string]any
	ExtractConfig       ExtractConfig
}

EffectiveProcessConfig is the merged view used by the parse pipeline.

type FallbackStrategy string

FallbackStrategy represents the fallback strategy type 

const (

	FallbackStrategyModel FallbackStrategy = "model" // Model fallback response
)

type FetchedItem 

type FetchedItem struct {
	// Unique ID in the external system
	ExternalID string `json:"external_id"`

	// Title of the content
	Title string `json:"title"`

	// Content in bytes (Markdown format preferred)

	// When created in external system. Zero when the source does not expose it.
	CreatedAt time.Time `json:"created_at"`

	// Additional metadata to preserve
	Metadata map[string]string `json:"metadata"`

	// Whether the item was deleted in the source
	IsDeleted bool `json:"is_deleted"`

	// Source resource ID (e.g., folder ID this document belongs to)
	SourceResourceID string `json:"source_resource_id"`

	// ReplacesSubtree, when true, tells ingestion to reconcile this item's
	// sub-items: after the parent is (re)ingested, every existing knowledge item
	// whose external_id starts with SubtreeChildPrefix(ExternalID) that is NOT
	// listed in SubtreeKeep is deleted as stale. Used by connectors that fan one
	// source node out into a parent document plus attachment/image sub-items
	// (e.g. Feishu docx).
	//
	// PRECONDITIONS the sweep relies on — a connector setting this MUST honour:
	//   1. Child external_ids are built with SubtreeChildID, so they share the
	//      '#' prefix the sweep matches. A child ID without that prefix is never
	//      swept (silently orphaned); an unrelated item that happens to start
	//      with the prefix would be wrongly swept.
	//   2. The parent is emitted (streaming) / listed (batch) no later than its
	//      children, and SubtreeKeep already names every still-present child when
	//      the parent is ingested. The sweep runs at parent-ingest time against
	//      the PRIOR sync's children, so a child emitted after its parent's sweep
	//      but absent from SubtreeKeep could be deleted right after being added.
	ReplacesSubtree bool `json:"replaces_subtree,omitempty"`

	// SubtreeKeep lists the external_ids of sub-items that still exist in the
	// source this sync. Consulted only when ReplacesSubtree is true: the sweep
	// preserves these children even if they could not be re-ingested this cycle
	// (transient download/parse failure, or an unclassifiable filename), so a
	// still-present attachment never loses its previously-synced good copy. Only
	// children absent from this set — genuinely removed from the source — are
	// swept.
	//
	// CONTRACT: an empty (or nil) SubtreeKeep with ReplacesSubtree=true means
	// "keep nothing" and sweeps EVERY existing child under the prefix. That is
	// correct for a node whose attachments all vanished, so a connector setting
	// ReplacesSubtree MUST populate SubtreeKeep with every child still present.
	// The field is consumed in-process (fetch → ingest, no serialization), so
	// nil and empty are equivalent here; the omitempty tag is for API/debug
	// exposure only and must not be relied on to distinguish "unset" from "empty".
	SubtreeKeep []string `json:"subtree_keep,omitempty"`
}

FetchedItem represents a single document/content item fetched from external source

type FollowUpSuggestionConfig 

type FollowUpSuggestionConfig struct {
	Enabled                        bool     `yaml:"enabled" json:"enabled"`
	Mode                           string   `yaml:"mode" json:"mode"`
	Count                          int      `yaml:"count" json:"count"`

	SuppressWhenAnswerAsksQuestion bool     `yaml:"suppress_when_answer_asks_question" json:"suppress_when_answer_asks_question"`
	KnowledgeFallback              bool     `yaml:"knowledge_fallback" json:"knowledge_fallback"`
	AllowRegenerate                bool     `yaml:"allow_regenerate" json:"allow_regenerate"`
}

FollowUpSuggestionConfig controls contextual questions generated after a completed assistant answer.

type ForkBootstrap 

type ForkBootstrap struct {
	SnapshotID      string     `json:"snapshot_id"`
	CommitSHA       string     `json:"commit_sha"`
	SourceSandboxID string     `json:"source_sandbox_id"`
	CreatedAt       time.Time  `json:"created_at"`
	ConsumedAt      *time.Time `json:"consumed_at,omitempty"`
}

ForkBootstrap carries the one-shot instructions a forked session needs the first time it provisions a sandbox: boot from SnapshotID instead of the config's template, then roll /workspace back to CommitSHA.

It is consumed exactly once. After ConsumedAt is set the forked session is indistinguishable from an ordinary session — matching the durability semantics every session already has, where a reaped sandbox loses /workspace.

func (ForkBootstrap) Consumed 

func (f ForkBootstrap) Consumed() bool

Consumed reports whether the bootstrap has already been applied.

func (*ForkBootstrap) Scan 

func (f *ForkBootstrap) Scan(value any) error

Scan implements the sql.Scanner interface for database deserialization.

func (ForkBootstrap) Value 

func (f ForkBootstrap) Value() (driver.Value, error)

Value implements the driver.Valuer interface for database serialization.

type ForkSnapshotLease 

type ForkSnapshotLease struct {
	SnapshotID      string    `json:"snapshot_id" gorm:"column:snapshot_id;primaryKey;type:varchar(128)"`
	TenantID        uint64    `json:"tenant_id" gorm:"column:tenant_id"`
	SandboxConfigID string    `json:"sandbox_config_id" gorm:"column:sandbox_config_id;type:varchar(36)"`
	CreatedAt       time.Time `json:"created_at" gorm:"column:created_at"`
}

ForkSnapshotLease is the durable record of a provider snapshot taken before the forked session row exists. CreateForked can fail or the process can crash in that window; the reaper scans these rows so a snapshot without a session is still collectable.

func (ForkSnapshotLease) TableName 

func (ForkSnapshotLease) TableName() string

TableName is the lease table. It is separate from sessions: a rolled-back CreateForked must not erase the only copy of the snapshot ID.

type FunctionCall 

type FunctionCall struct {
	Name      string `json:"name"`
	Arguments string `json:"arguments"` // JSON string
}

FunctionCall represents the function details

type FunctionDefinition 

type FunctionDefinition struct {
	Name        string          `json:"name"`
	Description string          `json:"description"`
	Parameters  json.RawMessage `json:"parameters"`
}

FunctionDefinition represents a function definition for LLM function calling

type GalleryAttrDef 

type GalleryAttrDef struct {
	Name        string             `json:"name"`
	Type        string             `json:"type"`
	Values      []GalleryAttrValue `json:"values,omitempty"`
	Label       string             `json:"label"`
	Description string             `json:"description,omitempty"`
	Usage       GalleryUsage       `json:"usage"`
}

GalleryAttrDef is one gallery-consumable attribute as a source declares it. Name is source-local (unprefixed); the gallery namespaces it under the declaring source's id when it builds the contract (see GalleryAttrID). Type drives frontend rendering: "text" (substring search), "date", "extent" (ordered value set -> multi-select), "presence" (boolean -> true/false checkboxes) and "keywords" (array of tags -> tag search).

Like values, the attribute itself carries a short Label for the UI and a longer Description for wherever there is room for a sentence.

type GalleryAttrSource 

type GalleryAttrSource struct {
	ID    string           `json:"id"`
	Attrs []GalleryAttrDef `json:"attrs"`
}

GalleryAttrSource is the aggregated view of one registered attribute source: the source id plus the attributes it provides for a KB.

func GalleryAttrSources 

func GalleryAttrSources(kbID string) []GalleryAttrSource

GalleryAttrSources resolves every registered source for a KB, in registration (priority) order. A source returning nothing yields an empty attribute list, not an error — an absent source is a normal state (e.g. the system attribute pipeline not deployed).

type GalleryAttrValue 

type GalleryAttrValue struct {
	// Value is the raw string the attribute can hold.
	Value string `json:"value"`
	// Label is the short, on-screen name for this value.
	Label string `json:"label"`
	// Description explains the value in a sentence; empty when the source
	// has nothing more to say.
	Description string `json:"description,omitempty"`
}

GalleryAttrValue is one allowed value of an attribute together with the words to show for it. A value carries two pieces of text on purpose: Label is the short name that goes on screen (a filter checkbox, a search field, a sort option), while Description holds the longer explanation that would blow a compact control apart if it were shown inline. Callers pick the one they need — the filter panel renders Label and moves Description into a tooltip, the detail panel can show both.

Value stays the raw machine value: it is what gets filtered, searched and stored in image_info, and it must never be localized.

type GalleryPolicyTier 

type GalleryPolicyTier struct {
	// Sources toggles whole attribute sources on/off, keyed by source id.
	// The highest tier that mentions a source decides its state; sources
	// nobody mentions are enabled.
	Sources map[string]bool `json:"sources,omitempty"`
	// Overrides adjusts per-attribute usage, keyed by namespaced attribute
	// id ("system:contain.text"). Overrides apply field by field on top of
	// whatever the lower tiers resolved.
	Overrides map[string]GalleryUsageOverride `json:"overrides,omitempty"`
	// Mode is the user-tier search activation mode: "all" (every eligible
	// search field active) or "custom" (per-field status governs). Empty
	// means "all". Only meaningful in the user tier.
	Mode string `json:"mode,omitempty"`
	// Status is the user-tier per-attribute search-field activation,
	// keyed by namespaced attribute id with values "on"/"off". Only
	// meaningful in the user tier.
	Status map[string]string `json:"status,omitempty"`
}

GalleryPolicyTier is the unified JSON schema shared by the system, KB and user configuration tiers. All fields are optional; an empty tier is a no-op.

type GalleryResolvedAttr 

type GalleryResolvedAttr struct {
	ID     string `json:"id"`
	Source string `json:"source"`
	Name   string `json:"name"`
	Type   string `json:"type"`
	// Values keeps each allowed value's raw form plus the short label to
	// show and the sentence to explain it. A source that declares no
	// values (a free-text or date attribute) simply omits the field.
	Values      []GalleryAttrValue `json:"values,omitempty"`
	Label       string             `json:"label"`
	Description string             `json:"description,omitempty"`
	Usage       GalleryUsage       `json:"usage"`
	// UsageFrom names the highest tier that touched this attribute's usage:
	// "source" | "system" | "kb" | "user". Debugging aid for "why does this
	// attribute (not) show up".
	UsageFrom string `json:"usage_from"`
}

GalleryResolvedAttr is one attribute as the gallery contract serves it to the frontend: the source's declaration with every tier's overrides already merged in. ID is the namespaced attribute id; Name stays source-local for raw lookups in image_info.

type GalleryResolvedConfig 

type GalleryResolvedConfig struct {
	// AttributeSources lists the live source ids in priority order.
	AttributeSources []string              `json:"attribute_sources"`
	Attributes       []GalleryResolvedAttr `json:"attributes"`
	// Mode is the user's search activation mode ("all" by default).
	Mode string `json:"mode"`
	// Status mirrors the user's per-field search toggles; nil means the
	// user has not recorded any yet.
	Status map[string]string `json:"status"`
}

GalleryResolvedConfig is the merged gallery contract: which sources are live, the resolved attribute list, and the user's search activation state.

func ResolveGalleryConfig 

func ResolveGalleryConfig(kbID string, system, kb, user *GalleryPolicyTier) *GalleryResolvedConfig

ResolveGalleryConfig merges the registered sources with the configuration tiers (system -> KB -> user, each overriding field by field) and returns the contract the gallery frontend renders from. A nil tier simply does not exist; the KB tier is reserved for the per-KB config (not wired yet — the engine already accepts it).

type GalleryUsage 

type GalleryUsage struct {
	// InFilter marks the attribute as renderable in the filter panel.
	InFilter bool `json:"in_filter"`
	// InSearchField marks the attribute as selectable in the search-field
	// checkboxes (the user still chooses per field whether to search it).
	InSearchField bool `json:"in_searchfield"`
	// InSortField marks the attribute as an option in the sort dropdown.
	InSortField bool `json:"in_sortfield"`
}

GalleryUsage declares how the image gallery may use one attribute. It is the "eligibility" layer: an attribute only appears in the gallery UI section (filter panel / search-field checkboxes / sort dropdown) that its usage flags allow. Whether a search field is actually active is decided separately by the user-level status layer, never here.

type GalleryUsageOverride 

type GalleryUsageOverride struct {
	InFilter      *bool `json:"in_filter,omitempty"`
	InSearchField *bool `json:"in_searchfield,omitempty"`
	InSortField   *bool `json:"in_sortfield,omitempty"`
}

GalleryUsageOverride is a field-level usage override. A nil field means "leave the lower tier's value alone"; a non-nil field replaces it.

type GalleryUserPrefs 

type GalleryUserPrefs struct {
	// Mode is "all" (every search-eligible field active) or "custom"
	// (per-field Status governs). Empty = "all".
	Mode string `json:"mode,omitempty"`
	// Status maps a namespaced attribute id ("builtin:caption") to
	// "on"/"off". Only consulted in custom mode; an unrecorded field is
	// off. Source-declared on/off does not exist — activation is always
	// the user's own record.
	Status map[string]string `json:"status,omitempty"`
}

GalleryUserPrefs is the user-tier slice of the gallery configuration. The full tier schema (types.GalleryPolicyTier) also allows usage overrides, but those are admin/operator concerns; the user layer only records the activation mode and which search fields they personally switched on.

type GeneratedQuestion 

type GeneratedQuestion struct {
	ID              string `json:"id"`                         // 唯一标识，用于构造 source_id
	Question        string `json:"question"`                   // 问题内容
	ContentRevision *int   `json:"content_revision,omitempty"` // 该问题对应的 Chunk 内容版本
}

GeneratedQuestion 表示AI生成的单个问题

type GenerationMetrics 

type GenerationMetrics struct {
	BLEU1 float64 `json:"bleu1"` // BLEU-1 score
	BLEU2 float64 `json:"bleu2"` // BLEU-2 score
	BLEU4 float64 `json:"bleu4"` // BLEU-4 score

	ROUGE1 float64 `json:"rouge1"` // ROUGE-1 score
	ROUGE2 float64 `json:"rouge2"` // ROUGE-2 score
	ROUGEL float64 `json:"rougel"` // ROUGE-L score
}

GenerationMetrics contains metrics for text generation evaluation

type GrantScope added in v0.9.0 

type GrantScope struct {
	Scope   string
	ScopeID string
	// BindingHash is the run's configuration; see AgentGrant.BindingHash.
	BindingHash string
}

GrantScope is where a run's grants are kept and looked up.

GrantScopeFromContext is the run's grant scope, if it has one.

func StandingGrantScopeFromContext added in v0.9.0 

func StandingGrantScopeFromContext(ctx context.Context) (GrantScope, bool)

StandingGrantScopeFromContext is the run's standing grant scope, if any.

type GraphBuilder 

type GraphBuilder interface {
	// BuildGraph constructs a knowledge graph from the provided document chunks.
	// It extracts entities and relationships, then builds the graph structure.
	BuildGraph(ctx context.Context, chunks []*Chunk) error

	// GetRelationChunks retrieves the IDs of chunks directly related to the specified chunk.
	// The topK parameter limits the number of results returned, based on relationship strength.
	GetRelationChunks(chunkID string, topK int) []string

	// GetIndirectRelationChunks finds chunk IDs that are indirectly connected to the specified chunk.
	// These are "second-degree" connections, useful for expanding the context during retrieval.
	GetIndirectRelationChunks(chunkID string, topK int) []string

	// GetAllEntities returns all entities currently in the knowledge graph.
	// This is primarily used for visualization and diagnostics.
	GetAllEntities() []*Entity

	// GetAllRelationships returns all relationships currently in the knowledge graph.
	// This is primarily used for visualization and diagnostics.
	GetAllRelationships() []*Relationship
}

GraphBuilder defines the interface for building and querying the knowledge graph. It provides methods to construct the graph from document chunks and retrieve related information.

type GraphData 

type GraphData struct {
	Text     string           `json:"text,omitempty"`
	Node     []*GraphNode     `json:"node,omitempty"`
	Relation []*GraphRelation `json:"relation,omitempty"`
}

type GraphNode 

type GraphNode struct {
	Name       string   `json:"name,omitempty"`
	Chunks     []string `json:"chunks,omitempty"`
	Attributes []string `json:"attributes,omitempty"`
	// Retrieval identities are local to the graph query, not extraction configuration.
	ID          string `json:"-" yaml:"-"`
	KnowledgeID string `json:"-" yaml:"-"`
}

type GraphRelation 

type GraphRelation struct {
	Node1 string `json:"node1,omitempty"`
	Node2 string `json:"node2,omitempty"`
	Type  string `json:"type,omitempty"`
	// Names are for display; these identities link to the actual document instances.
	ID       string `json:"-" yaml:"-"`
	SourceID string `json:"-" yaml:"-"`
	TargetID string `json:"-" yaml:"-"`
}

GraphRelation represents the relation of the graph

type GraphSearchCandidates added in v0.9.0 

type GraphSearchCandidates struct {
	Graph             *GraphData
	TruncationReasons []string
}

GraphSearchCandidates is internal: physical graph identities never cross the public API boundary. Truncation reports candidate caps, not an invented total.

type GraphSearchEntity added in v0.9.0 

type GraphSearchEntity struct {
	ID             string   `json:"id"`
	Name           string   `json:"name"`
	KnowledgeID    string   `json:"knowledge_id"`
	Attributes     []string `json:"attributes"`
	SourceChunkIDs []string `json:"source_chunk_ids"`
}

GraphSearchEntity identifies an entity instance within a live document.

type GraphSearchMeta added in v0.9.0

	MaxRelations      int      `json:"max_relations"`
	MaxSourceChunks   int      `json:"max_source_chunks"`
}

GraphSearchMeta reports effective limits and observed clipping, not totals.

type GraphSearchRelation struct {
	ID             string   `json:"id"`
	SourceID       string   `json:"source_id"`
	TargetID       string   `json:"target_id"`
	Type           string   `json:"type"`
	SourceChunkIDs []string `json:"source_chunk_ids"`
}

GraphSearchRelation connects two returned, same-document entities.

type GraphSearchRequest added in v0.9.0 

type GraphSearchRequest struct {
	Query           string `json:"query" binding:"required" minLength:"1" maxLength:"512"`
	MaxNodes        int    `json:"max_nodes" minimum:"0" maximum:"100" default:"50"`
	MaxRelations    int    `json:"max_relations" minimum:"0" maximum:"200" default:"100"`
	MaxSourceChunks int    `json:"max_source_chunks" minimum:"0" maximum:"50" default:"20"`
}

GraphSearchRequest matches a case-sensitive entity-name substring. It does not run a model, generate embeddings or change the regular retrieval pipeline.

func (*GraphSearchRequest) Normalize added in v0.9.0 

func (r *GraphSearchRequest) Normalize() error

Normalize validates both HTTP and direct service callers. Zero means default.

type GraphSearchResult added in v0.9.0 

type GraphSearchResult struct {
	KnowledgeBaseID string                   `json:"knowledge_base_id"`
	Query           string                   `json:"query"`
	Entities        []GraphSearchEntity      `json:"entities"`
	Relationships   []GraphSearchRelation    `json:"relationships"`
	SourceChunks    []GraphSearchSourceChunk `json:"source_chunks"`
	Meta            GraphSearchMeta          `json:"meta"`
}

GraphSearchResult is the stable public JSON contract, separate from GraphData.

type GraphSearchSourceChunk added in v0.9.0 

type GraphSearchSourceChunk struct {
	ID               string `json:"id"`
	KnowledgeID      string `json:"knowledge_id"`
	Title            string `json:"title"`
	Content          string `json:"content"`
	ChunkIndex       int    `json:"chunk_index"`
	StartAt          int    `json:"start_at"`
	EndAt            int    `json:"end_at"`
	ContentTruncated bool   `json:"content_truncated" gorm:"-"`
	TitleTruncated   bool   `json:"title_truncated" gorm:"-"`
	TenantID         uint64 `json:"-"`
	KnowledgeBaseID  string `json:"-"`
}

GraphSearchSourceChunk is a bounded, live SQL projection, not a raw Chunk or Knowledge row. It excludes file paths, metadata, image URLs and owner details.

type History 

type History struct {
	Query               string     // User query text
	Answer              string     // System response text
	CreateAt            time.Time  // When this history entry was created
	KnowledgeReferences References // Knowledge references used in the answer
}

History represents a conversation history entry Contains query-answer pairs and associated knowledge references Used for tracking conversation context and history

type HostApprovalSnapshot added in v0.9.0 

type HostApprovalSnapshot struct {
	Reason          string   `json:"reason"`
	Command         string   `json:"command,omitempty"`
	Cwd             string   `json:"cwd,omitempty"`
	GrantPath       string   `json:"grant_path,omitempty"`
	GrantAccess     string   `json:"grant_access,omitempty"`
	DenialSnippet   string   `json:"denial_snippet,omitempty"`
	FirstAttemptRan bool     `json:"first_attempt_ran,omitempty"`
	AllowSession    bool     `json:"allow_session"`
	SessionRules    []string `json:"session_rules,omitempty"`
}

HostApprovalSnapshot is the Lite host card stored with a tool approval.

type ImageActionID added in v0.9.0 

type ImageActionID string

ImageActionID is the dispatch key of an image action. A pipeline references an action by this id; which code runs for that id is decided by the registry, so adding an action is one entry here plus a binding, not a new branch in a loop. 

const (
	// ImageActionCaption asks the model for a short description of the image
	// and stores it as the caption slot.
	ImageActionCaption ImageActionID = "caption"
	// ImageActionObservation observes the registered attributes
	// (contain.text, contain.data_visual, ...) and describes the image in the
	// same answer. One VLM request fills the attribute slots and the caption
	// slot, which is why there is no standalone observation action and no
	// "merge observation with caption" rule anywhere in the framework.
	ImageActionObservation ImageActionID = "observation"
	// ImageActionOCR extracts the text the image carries, when the policy wants
	// it.
	ImageActionOCR ImageActionID = "ocr"
	// ImageActionPreprocess straightens and crops a photographed page before
	// OCR runs, so the OCR pass sees an upright, content-tight image. It is
	// pure: it talks to the local document preprocessor, never to a VLM, and
	// a preprocessor that is absent or fails leaves the image untouched —
	// which is why it writes a slot instead of replacing the run's image
	// reference outright.
	ImageActionPreprocess ImageActionID = "preprocess"
)

type ImageActionImpl added in v0.9.0 

type ImageActionImpl string

ImageActionImpl records how an action does its work. The flag is not decoration: an action that calls a model to check an existing value has stopped checking and started generating again. 

const (
	// ImageActionImplPure runs without a model.
	ImageActionImplPure ImageActionImpl = "pure"
	// ImageActionImplVLM spends one or more model requests.
	ImageActionImplVLM ImageActionImpl = "vlm"
)

type ImageActionSpec added in v0.9.0 

type ImageActionSpec struct {
	// ID dispatches the action inside a pipeline; it is also how a pipeline
	// refers to it and how the gallery and the settings panel name it.
	ID ImageActionID
	// Impl says whether the action may call a model.
	Impl ImageActionImpl
	// Writes lists the output slots the action fills; nil means it writes none.
	// Two actions of one pipeline may write the same slot on purpose — the
	// iterate and validate shapes both overwrite what they just read — so
	// uniqueness is deliberately not asserted here.
	Writes []string
	// Reads lists the slots the action consumes. Declaration only: it produces
	// trace output, it does not order the pipeline.
	Reads []string
	// Version fingerprints the prompts and rules the action encodes, so a trace
	// row can be matched back to the revision that produced an image rather
	// than only to the pipeline that ran.
	Version string
	// Fields are the per-action tunables the settings panel renders. A field's
	// key is the action's own namespace plus its bare name — build it with
	// ActionParam(id, name), never by hand — so the caption's "thinking" and
	// the OCR's "thinking" are two keys that cannot collide. A pipeline carries
	// the declaration by reference (see ActionField) rather than re-declaring or
	// re-spelling it; the value is the carrying pipeline's own, stored under its
	// slot, so two pipelines may offer the same action's tunable without either
	// reading the other's answer.
	Fields []ImageFieldDef
}

ImageActionSpec is the declarative half of an action: what it is allowed to write, what it declares to read, and the knobs a settings panel may expose. The executable half is bound by the registry.

type ImageActionsConfig 

type ImageActionsConfig struct {
	OCR ImageOCRAction `json:"ocr"`
}

ImageActionsConfig is the attribute -> work policy. It is keyed by downstream action (today only "ocr"); each action lists the attribute conditions that turn it on.

What to do when a driving attribute was NOT observed is not part of this table — that is a scheduling decision and lives with the pipeline that does the scheduling, as its own `ocr_on_unobserved` setting. The consequence for a stored config is deliberate: a `on_unobserved` written into this table before that move is ignored rather than honoured from two places.

func DefaultImageActions 

func DefaultImageActions() ImageActionsConfig

DefaultImageActions is the built-in attribute -> work table: OCR runs when contain.text is "block" or contain.data_visual is true. It is equivalent to the old class table: decorative / logo / photo (text reliably absent or captured by the description) skip OCR; text_screenshot / table / chart / other run OCR.

func MergeImageActions 

func MergeImageActions(custom ImageActionsConfig) ImageActionsConfig

MergeImageActions folds a knowledge base's custom action table on top of the built-in one, per action key. A custom OCR.On replaces the default OCR.On wholesale (the "on" list is a unit); anything the custom table does not mention keeps the default. This lets a knowledge base tune OCR without spelling out every condition, and keeps a future action key added to the default from being wiped by an older stored config.

func ResolveImageActions 

func ResolveImageActions(p *ImageActionsConfig) ImageActionsConfig

ResolveImageActions returns the effective policy: a nil config uses the default; a non-nil config is merged so forward-compatible.

type ImageAsset 

type ImageAsset struct {
	// ID is stable and unique within a KB: "<chunkID>#<index-in-array>".
	ID string `json:"id"`
	// ChunkID is the owning chunk (text chunk for embedded images, or the
	// image_ocr / image_caption chunk for dedicated image assets).
	ChunkID string `json:"chunk_id"`
	// KnowledgeID is the document/knowledge item the image belongs to.
	KnowledgeID string `json:"knowledge_id"`
	// SourceName is the human-readable name of the source knowledge item
	// (document), resolved from KnowledgeID. Empty when the item no longer
	// exists (e.g. deleted), in which case KnowledgeID is still shown.
	SourceName string `json:"source_name"`
	// ChunkType is the owning chunk's type; empty for images discovered on a
	// text (document) chunk. Helps the UI label the source.
	ChunkType string `json:"chunk_type"`
	// URL is the rendered image URL (COS / storage provider).
	URL string `json:"url"`
	// OriginalURL is the pre-transform source reference, when different.
	OriginalURL string `json:"original_url"`
	// Caption is the model-generated image description.
	Caption string `json:"caption"`
	// OCRText is the extracted text from the image, if any.
	OCRText string `json:"ocr_text"`
	// Attrs is the observed attribute map (e.g. contain.text, contain.data_visual)
	// produced by the attribute pipeline. Absent keys mean "not observed".
	Attrs map[string]any `json:"attrs"`
	// IsEnabled mirrors the owning chunk's enabled flag.
	IsEnabled bool `json:"is_enabled"`
	// Status mirrors the owning chunk's index status.
	Status int `json:"status"`
	// CreatedAt is the owning chunk's creation time.
	CreatedAt time.Time `json:"created_at"`
	// UpdatedAt is the owning chunk's last update time.
	UpdatedAt time.Time `json:"updated_at"`
}

ImageAsset is a single image projected from a chunk's image_info array. It is the unit the gallery lists, filters, sorts and serves.

type ImageAssetField 

type ImageAssetField struct {
	// Builtin is one of the builtin source's fields: "caption", "ocr_text",
	// "created_at", "updated_at" or "is_enabled".
	Builtin string
	// Attr is a source-local attribute name read from image_info attrs
	// (e.g. "contain.text").
	Attr string
}

ImageAssetField names one value of an image the gallery query can search, filter or sort on. Exactly one of the two is set.

type ImageAssetQuery 

type ImageAssetQuery struct {
	// Keyword is matched, lowercased, as a substring of the SearchFields'
	// values joined by spaces. Empty disables the keyword match.
	Keyword      string
	SearchFields []ImageAssetField
	// AttrFilters are AND-ed across sets and OR-ed within one; an image
	// without a value for the field is not constrained by it.
	AttrFilters []ImageAssetValueSet
	// OnRules / OffRules are the per-value verdicts: an image carrying an
	// "off" value is hidden unless it also carries an "on" value.
	OnRules  []ImageAssetValueSet
	OffRules []ImageAssetValueSet
	// IsEnabled, when non-nil, restricts to chunks with that enabled state.
	IsEnabled *bool
	// KnowledgeIDs, when non-empty, restricts to images owned by these
	// knowledge items.
	KnowledgeIDs []string
	SortField    ImageAssetField
	SortDesc     bool
	Offset       int
	Limit        int
}

ImageAssetQuery is the storage-neutral form of one gallery page request. The service translates namespaced attribute ids into fields; the repository compiles it into SQL, so de-duplication, filtering, sorting and paging all run in the database and only the requested page leaves it.

type ImageAssetRow 

type ImageAssetRow struct {
	ChunkID     string    `gorm:"column:chunk_id"`
	KnowledgeID string    `gorm:"column:knowledge_id"`
	ChunkType   string    `gorm:"column:chunk_type"`
	IsEnabled   bool      `gorm:"column:is_enabled"`
	Status      int       `gorm:"column:status"`
	CreatedAt   time.Time `gorm:"column:created_at"`
	UpdatedAt   time.Time `gorm:"column:updated_at"`
	ImageIndex  int       `gorm:"column:image_index"`
	URL         string    `gorm:"column:url"`
	OriginalURL string    `gorm:"column:original_url"`
	Caption     string    `gorm:"column:caption"`
	OCRText     string    `gorm:"column:ocr_text"`
	// AttrsJSON is the observed attribute map as JSON text.
	AttrsJSON  string `gorm:"column:attrs_json"`
	TotalCount int64  `gorm:"column:total_count"`
}

ImageAssetRow is one de-duplicated image as the repository returns it: a chunk_images row, the owning chunk's columns plus the image entry's fields.

type ImageAssetValueSet 

type ImageAssetValueSet struct {
	Field  ImageAssetField
	Values []string
}

ImageAssetValueSet pairs a field with a set of raw values.

type ImageAttrCondition 

type ImageAttrCondition struct {
	Prop string `json:"prop"`
	Is   string `json:"is"`
}

ImageAttrCondition is one attribute match: attr Prop equals Is.

type ImageAttrSource 

type ImageAttrSource struct {
	Schema string `json:"schema"`           // ImageAttrSchemaVersion
	Prompt string `json:"prompt"`           // prompt fingerprint (version + whether custom instructions were appended)
	Custom bool   `json:"custom,omitempty"` // true if the describe prompt carried user custom instructions
}

ImageAttrSource records how an observation was produced, so post-split data can be bucketed by provenance and evaluations do not mix sources.

type ImageAttrs 

type ImageAttrs struct {
	Schema string          `json:"schema"`
	Source ImageAttrSource `json:"source"`
	Attrs  map[string]any  `json:"attrs,omitempty"`
}

ImageAttrs is the persisted observation result. Attrs is a map, not a fixed struct, so adding an attribute never breaks storage or rows written before the attribute existed. Stored inside chunks.image_info as JSON; no migration.

func (ImageAttrs) DataVisual 

func (a ImageAttrs) DataVisual() bool

DataVisual returns the observed contain.data_visual value, or false when the attribute was not observed. Absence is not the same as an observed "false" — use Observed to distinguish them, which is what DecideOCR does.

func (ImageAttrs) Margin added in v0.9.0 

func (a ImageAttrs) Margin() string

Margin returns the observed layout.margin value ("none" | "small" | "large"), or "" when the observation did not answer for it. The empty string is meaningful and must not be read as "none": it says this run has no basis to conclude the page is already tidy, and callers treat that as "worth a look" so an unobserved page still gets its chance.

func (ImageAttrs) Observed 

func (a ImageAttrs) Observed(name string) bool

Observed reports whether an attribute key was present in the observation.

func (ImageAttrs) TextExtent 

func (a ImageAttrs) TextExtent() string

TextExtent returns the observed contain.text value, or "" when the attribute was not observed. Use Observed("contain.text") to tell an absent attribute apart from one the model answered; "" is never a legal observed value.

func (ImageAttrs) Upright added in v0.9.0 

func (a ImageAttrs) Upright() (upright bool, observed bool)

Upright reports whether the observation found the text upright, and whether it answered the question at all. A presence attribute stores a real bool (see coerceAttrValue), so this is deliberately not a plain bool accessor: "the model said not upright" and "the model did not say" call for different behaviour, and collapsing them would turn an unanswered attribute into a confident "it is upright" that skips a page which needed straightening.

type ImageFieldDef added in v0.9.0 

type ImageFieldDef struct {
	// Key is the name the action reads with r.Param(key).
	Key string `json:"key"`
	// Type selects the control the panel renders.
	Type ImageFieldType `json:"type"`
	// Label and Description are written in the project's default language; the
	// frontend overlays its translations and falls back to these.
	Label       string `json:"label"`
	Description string `json:"description"`
	// Default applies when the knowledge base does not override the field.
	Default any `json:"default"`
	// Options enumerates the allowed values of an enum field.
	Options []string `json:"options"`
	// Group says which run of the panel the field belongs to: the switches
	// shown outright, the switches folded under "advanced", or the explanation
	// text folded under "notes". The zero value is ImageFieldGroupSwitch, so a
	// pipeline says nothing about groups until it has something to fold away.
	Group ImageFieldGroup `json:"group,omitempty"`
	// DecidesAction marks a field that turns one of the pipeline's actions on or
	// off, as opposed to one that tunes a call the pipeline always makes. Only
	// such a field can leave a pipeline with nothing left to do, and only such
	// a field is named by the rules of ImagePipelineRules.
	DecidesAction bool `json:"decides_action"`
}

ImageFieldDef is one tunable of an action as the settings panel sees it. Its json tags are snake_case to match the rest of the image API, including the enclosing ImagePipelineSpec.

Key is either a bare name owned by the declaring pipeline ("caption_enabled") or an action-namespaced one built with ActionParam ("ocr.thinking_enabled"). A key never carries a pipeline prefix: one run serves one pipeline, and the run's trace names it once. See docs/design/image-pipeline-naming.md.

func ActionField added in v0.9.0 

func ActionField(id ImageActionID, param string) (ImageFieldDef, bool)

ActionField returns the tunable an action declares under a bare name ("thinking"), and whether it declares one. Callers use it to carry an action's control into a pipeline's panel without spelling the key themselves.

type ImageFieldGroup added in v0.9.0 

type ImageFieldGroup string

ImageFieldGroup is the run of a panel a declared field belongs to. Fields are declared in three consecutive runs, and the panel renders them as three places:

  1. ImageFieldGroupSwitch — the standing switches, always on screen;
  2. ImageFieldGroupAdvanced — switches folded under "advanced";
  3. ImageFieldGroupNote — explanations folded under "notes".

A field declared outside its run would silently jump to another part of the panel, so the order is not a matter of taste: TestFieldDeclarationOrder enforces it for every registered pipeline. 

const (
	// ImageFieldGroupSwitch is a switch the panel always shows. It is the zero
	// value, so a standing switch does not have to mention its group.
	ImageFieldGroupSwitch ImageFieldGroup = "switch"
	// ImageFieldGroupAdvanced is a switch that only matters to someone tuning
	// the pipeline; the panel folds it away by default.
	ImageFieldGroupAdvanced ImageFieldGroup = "advanced"
	// ImageFieldGroupNote is explanation text: no control, no value.
	ImageFieldGroupNote ImageFieldGroup = "note"
)

type ImageFieldType added in v0.9.0 

type ImageFieldType string

ImageFieldType is the control a tunable renders as. 

const (
	// ImageFieldTypeBool renders as a switch or checkbox.
	ImageFieldTypeBool ImageFieldType = "bool"
	// ImageFieldTypeString renders as a text input.
	ImageFieldTypeString ImageFieldType = "string"
	// ImageFieldTypeEnum renders as a select over the field's Options.
	ImageFieldTypeEnum ImageFieldType = "enum"
	// ImageFieldTypeNote renders no control at all: the field is an explanation
	// the pipeline declares next to the switches it explains, and the panel
	// shows it in the folded notes block. It carries no value, so its Key is
	// only a name for the entry.
	ImageFieldTypeNote ImageFieldType = "note"
)

type ImageInfo 

type ImageInfo struct {
	// SHA256 identifies the exact stored image bytes across parser and preview.
	SHA256 string `json:"sha256,omitempty"`
	// 图片URL（COS）
	URL string `json:"url"          gorm:"type:text"`
	// 原始图片URL
	OriginalURL string `json:"original_url" gorm:"type:text"`
	// 图片在文本中的开始位置
	StartPos int `json:"start_pos"`
	// 图片在文本中的结束位置
	EndPos int `json:"end_pos"`
	// 图片描述
	Caption string `json:"caption"`
	// 图片OCR文本
	OCRText string `json:"ocr_text"`
	// Attrs 是描述轮给出的图片属性观察结果（取值见 ImageAttrs / ImageAttrRegistry）。
	// 只记录模型确实回答了的属性：观察失败或取值非法的属性不会写入默认值，而是直接缺键，
	// 因此读取方必须用 ImageAttrs.Observed 区分「未观察到」与「观察到了负值」。
	// 该字段以 JSON 存储在 chunks.image_info 中，无需迁移；属性观察能力上线前写入的
	// 行会缺省为空，读取方必须容忍空值。
	Attrs ImageAttrs `json:"attrs,omitempty"`
}

ImageInfo 表示与 Chunk 关联的图片信息

type ImageListFilter 

type ImageListFilter struct {
	// Keyword is matched as a case-insensitive substring against the union
	// of the SearchIn fields' values.
	Keyword string
	// SearchIn lists the namespaced attribute ids to search. Empty means
	// the gallery default (builtin caption + ocr_text). The handler only
	// forwards ids whose resolved usage has in_searchfield=true.
	SearchIn []string
	// SortBy is a namespaced attribute id with in_sortfield=true. The bare
	// legacy values ("created_at", "updated_at", "caption") are still
	// accepted and mapped onto their builtin ids.
	SortBy string
	// SortOrder is "asc" or "desc".
	SortOrder string
	// AttrFilters maps a namespaced attribute id to the set of allowed
	// values. Values within one attribute are OR-ed; attributes are
	// AND-ed. An attribute present in this map but with no value on an
	// image fails the match (so "unobserved" is a distinct, filterable
	// state). The older, positional form of attribute filtering; see
	// AttrRules for the per-value verdicts the gallery panel now edits.
	AttrFilters map[string][]string
	// AttrRules maps a namespaced attribute id to a verdict per allowed
	// value: "" (or absent) leaves the image alone, "off" hides it, "on"
	// shows it. A verdict only speaks about images that actually carry
	// that value, so an image is judged by the rules it matches.
	//
	// When more than one rule speaks about the same image, "on" outranks
	// "off": a forced display beats a forced hide. Everything unclaimed
	// stays visible, which is what makes the default state usable — a
	// filter narrows the list, it never empties it.
	AttrRules map[string]map[string]string
	// IsEnabled, when non-nil, restricts to chunks with that enabled state.
	IsEnabled *bool
	// KnowledgeIDs, when non-empty, restricts the listing to images whose
	// owning document is one of these knowledge items. The handler caps the
	// list so a caller cannot send an unbounded IN clause.
	KnowledgeIDs []string
}

ImageListFilter holds the gallery query constraints coming from the UI. Attribute references use namespaced gallery attribute ids ("<sourceID>:<name>", e.g. "builtin:caption", "system:contain.text").

type ImageMultimodalPayload 

type ImageMultimodalPayload struct {
	TracingContext
	TenantID        uint64 `json:"tenant_id"`

	// unambiguous relative to the pipeline that reads it. A key the running
	// pipeline does not declare is ignored, which is what lets a stored
	// knowledge base keep working after a pipeline stops reading one.
	// ImagePipelineID is the pipeline this task runs, resolved from the
	// knowledge base at enqueue time by types.ResolveImagePipelineID. It
	// travels in the payload rather than being re-read at handle time for the
	// same reason ImageAttrsEnabled does: a task already in flight was
	// enqueued for one pipeline and must not be re-routed by a later edit.
	ImagePipelineID     ImagePipelineID `json:"image_pipeline,omitempty"`
	ImagePipelineParams map[string]any  `json:"image_pipeline_params,omitempty"`
	// Language is the request locale for {{language}} in prompt templates.
	Language string `json:"language,omitempty"`
	// ImageSourceType drives the OCR prompt, e.g. "scanned_pdf".
	ImageSourceType string `json:"image_source_type,omitempty"`
	// Attempt links this image task back to the parent ProcessDocument
	// attempt so the worker can record its image[i] subspan under the
	// same attempt's multimodal stage span.
	Attempt int `json:"attempt,omitempty"`
	// ImageIndex is the 0-based ordinal of this image inside the
	// parent's image set. Used as the subspan name suffix
	// ("multimodal.image[3]") so the timeline preserves order.
	ImageIndex int `json:"image_index,omitempty"`
	// ImageAttrsEnabled selects which image pipeline the task runs — see
	// types.ImagePipelineIDFor and the ImagePipelineID constants. True is the
	// attribute-observed pipeline: the describe round also observes image
	// attributes, and the attribute policy decides whether OCR runs for it.
	// False is the upstream behaviour: a plain caption, then OCR, no attribute
	// observation. In flight tasks enqueued before the field existed read
	// false, which is what they were enqueued for — the reason the flag travels
	// in the payload rather than being re-read from the knowledge base at handle
	// time.
	ImageAttrsEnabled bool `json:"image_attrs_enabled,omitempty"`
	// ImageVectorEnabled is resolved at enqueue time. nil preserves the KB
	// fallback for tasks queued before per-document indexing overrides existed.
	ImageVectorEnabled *bool `json:"image_vector_enabled,omitempty"`
	// ImageActions is the attribute→work table, resolved from the KB config at
	// enqueue time. A task without it — one already in flight when attribute
	// observation shipped — falls back to the conservative policy: run OCR.
	ImageActions ImageActionsConfig `json:"image_actions,omitempty"`
	// SourceLocators place the image in the original file; copied onto the
	// OCR and caption chunks built from it.
	SourceLocators SourceLocators `json:"source_locators,omitempty"`
}

ImageMultimodalPayload represents the image multimodal processing task payload.

type ImageOCRAction 

type ImageOCRAction struct {
	// On is the list of attribute conditions that enable OCR. Matching any one
	// turns OCR on.
	On []ImageAttrCondition `json:"on"`
}

ImageOCRAction is the OCR clause of the image_actions policy.

type ImagePipelineID added in v0.9.0 

type ImagePipelineID string

ImagePipelineID labels which image pipeline produced a run. It is recorded on the per-image subspan input, because reading the stored image_info alone cannot distinguish an image whose pipeline observed the attributes and then skipped OCR from one whose pipeline never observed anything. 

const (
	// ImagePipelineSmartOCR observes the registered attributes first, captions
	// in the same answer, then OCRs only when the attribute policy allows it.
	// The id promises that observation comes before the decision; it does not
	// promise that those three actions are the whole story.
	ImagePipelineSmartOCR ImagePipelineID = "smartocr"
	// ImagePipelineDefault is the manual path: the user picks which parsing
	// actions run, and each runs for every image with no observation and no
	// policy. It is the fallback whenever nothing else has been chosen.
	ImagePipelineDefault ImagePipelineID = "default"
	// ImagePipelineLegacyObCapOCR is the id ImagePipelineSmartOCR carried
	// before it was renamed to match the label the panel shows. Configs saved
	// since 2026-09 may name it, so it is normalized rather than honoured:
	// see NormalizeImagePipelineID.
	ImagePipelineLegacyObCapOCR ImagePipelineID = "ob_cap_ocr"
	// ImagePipelineLegacyCaptionOCR is the id ImagePipelineDefault carried
	// before the panel was reworked. Stored configs may still name it, so it
	// is normalized rather than honoured: see NormalizeImagePipelineID.
	ImagePipelineLegacyCaptionOCR ImagePipelineID = "caption_ocr"
)

func ImagePipelineIDFor added in v0.9.0 

func ImagePipelineIDFor(attrsEnabled bool) ImagePipelineID

ImagePipelineIDFor maps the attribute-observation switch to a pipeline id, so the trace label and the pipeline that actually runs can never disagree.

func NormalizeImagePipelineID added in v0.9.0 

func NormalizeImagePipelineID(id ImagePipelineID) ImagePipelineID

NormalizeImagePipelineID maps a stored pipeline id onto the id this build registers. A rename must not strand the knowledge bases that stored the old spelling, so every id that once named a shipped pipeline keeps resolving to its successor; unknown ids pass through unchanged and the caller falls back.

func ResolveImagePipelineID added in v0.9.0 

func ResolveImagePipelineID(cfg *ImageProcessingConfig) ImagePipelineID

ResolveImagePipelineID returns the pipeline id a knowledge base asks for. An explicit ImagePipelineID wins; without one the old attribute-observation switch still decides, so a knowledge base saved before the selector existed runs the pipeline the switch pointed at. An id that no pipeline registers is ignored here and falls back to the switch, which is what keeps a stored config from pointing at a pipeline that has since been removed.

type ImagePipelineRules added in v0.9.0 

type ImagePipelineRules struct {
	// AtLeastOne is satisfied when at least one field of Fields is on, and
	// fails when all of them are off: a set of switches that would leave the
	// image with nothing done to it.
	AtLeastOne []string `json:"at_least_one,omitempty"`
	// MessageKey is the frontend i18n key for the warning shown when this rule
	// is not met.
	MessageKey string `json:"message_key"`
	// Field names the control the panel points at, so the user is told which
	// switch to turn back on rather than simply that something is wrong.
	// The first of Fields when it is left empty.
	Field string `json:"field,omitempty"`
}

ImagePipelineRules are the conditions a pipeline's tunables have to meet before they can be saved. They travel with the pipeline's spec, and the settings panel evaluates them generically: the frontend knows no rule of its own, it only reads what the pipeline here declared and reports the result. A pipeline whose choices cannot conflict — the smart one schedules its own actions — declares none, and no switch it offers can ever be called invalid.

type ImagePipelineSpec added in v0.9.0 

type ImagePipelineSpec struct {
	// ID matches imagePipeline.ID(); it is what the knowledge base stores.
	ID ImagePipelineID `json:"id"`
	// Name is the human-readable label; the frontend overlays its translation
	// and falls back to this text.
	Name string `json:"name"`
	// Description tells the user how this pipeline works, shown under the
	// pick. Like Name it is overlay-translated with this text as fallback.
	Description string `json:"description"`
	// Fields are this pipeline's private tunables. The frontend renders one
	// control per field and posts them back under the pipeline's own slot, so
	// two pipelines can each own a field named "ocr_enabled" without either
	// seeing the other's.
	Fields []ImageFieldDef `json:"fields"`
	// Rules are conditions over those fields that have to hold before the
	// knowledge base can save them. Empty means the pipeline accepts any
	// combination of what it offers.
	Rules []ImagePipelineRules `json:"rules,omitempty"`
}

ImagePipelineSpec is how a pipeline presents itself to the settings panel. The frontend reads this shape instead of knowing any pipeline by name, so adding a pipeline is one registered file plus its translation, with no UI change; Fields carry the same shapes the panel renders today.

type ImagePipelineValidationError added in v0.9.0 

type ImagePipelineValidationError struct {
	// MessageKey is the frontend i18n key naming what is wrong.
	MessageKey string `json:"message_key"`
	// Field names the field at fault when a single one is. The panel points at
	// that control instead of at the section, which is what makes "switch one
	// of them back on" actionable. Empty means the whole configuration is at
	// fault.
	Field string `json:"field,omitempty"`
}

ImagePipelineValidationError is what a pipeline returns when the tunables a knowledge base saved for it cannot be run as they stand. It carries an i18n key rather than a sentence: the settings panel asks the backend whether what it shows can be saved, and every string on that panel is translated on the frontend — a bare English sentence here would be the one string in the UI that escapes the overlay.

func (*ImagePipelineValidationError) Error added in v0.9.0 

func (e *ImagePipelineValidationError) Error() string

type ImageProcessingConfig 

type ImageProcessingConfig struct {
	// Model ID used when describing images. Empty uses the knowledge base's caption model.
	ModelID string `yaml:"model_id" json:"model_id" extensions:"x-agent=image_model_id"`
	// ImageActions overrides the built-in attribute→work table (see
	// DefaultImageActions). A nil value keeps the conservative default: run OCR
	// for block text and data visuals. What to do about an image whose
	// attributes were NOT observed is deliberately not part of this table — it
	// is a scheduling decision, so it belongs to the pipeline that observes
	// (`ocr_on_unobserved` in that pipeline's slot).
	ImageActions *ImageActionsConfig `yaml:"image_actions,omitempty" json:"image_actions,omitempty"`
	// ImageAttrsEnabled turns the attribute-observed image pipeline on for this
	// knowledge base. It is off by default on purpose, so upgrading an
	// existing deployment never changes what happens to documents already
	// being ingested: with it off every image is described and OCR'd exactly
	// as before. When on, the describe round also observes image attributes and
	// the attribute policy decides whether OCR runs for it. A single upload can
	// override it per document through
	// KnowledgeProcessOverrides.ImageAttrsEnabled.
	ImageAttrsEnabled bool `yaml:"image_attrs_enabled,omitempty" json:"image_attrs_enabled,omitempty" extensions:"x-agent"` //nolint:lll // one-line struct tag
	// ImagePipelineID selects the image pipeline by id, so the choice the
	// settings panel offers is the choice the backend runs. It is unset on
	// knowledge bases configured before the field existed; those follow
	// ImageAttrsEnabled — see ResolveImagePipelineID. An explicit id always
	// wins over the switch.
	ImagePipelineID string `yaml:"image_pipeline,omitempty" json:"image_pipeline,omitempty" enums:"default,smartocr" extensions:"x-agent"`
	// ImagePipelineParams holds the tunables of ImagePipelineID, keyed by each
	// field's slot — the pipeline id joined to the field's own key, built by
	// SlotKey and read back by ImagePipelineParam. The map travels whole: a key
	// a pipeline no longer declares is dropped when the run reads it, so an old
	// stored config stays loadable rather than being rewritten on save.
	ImagePipelineParams map[string]any `` /* 172-byte string literal not displayed */
	// ImageVectorEnabled lets a knowledge base whose embedding model takes
	// images index each image by its own vector and recall it with one. It
	// is off by default on purpose: a model that takes images is also used
	// for plain text, and turning this on costs an embedding call per image
	// and widens vector recall. Existing knowledge bases stay off after an
	// upgrade because the stored JSON has no such key.
	ImageVectorEnabled bool `yaml:"image_vector_enabled,omitempty" json:"image_vector_enabled,omitempty" extensions:"x-agent"` //nolint:lll // one-line struct tag
}

ImageProcessingConfig represents the image processing configuration

type ImageRef 

type ImageRef struct {
	Filename    string
	OriginalRef string
	MimeType    string
	StorageKey  string
	ImageData   []byte // inline image bytes (universal fallback for cross-machine deployments)
	// IsOriginal marks references that point to the originally uploaded file
	// itself (e.g. when the user uploads a standalone image). Such references
	// must not be dropped by the icon/size filter — otherwise a small image
	// upload would be silently discarded before multimodal processing.
	IsOriginal bool
}

ImageRef represents an image reference extracted from the document.

type IndexConfig 

type IndexConfig struct {
	// --- Existing fields ---

}

IndexConfig holds optional index/collection configuration for the vector store. If empty, engine-specific defaults are used.

func (*IndexConfig) GetBucketsNum 

func (c *IndexConfig) GetBucketsNum(def int) int

GetBucketsNum returns the configured buckets_num (Doris), or def if unset/zero.

func (*IndexConfig) GetDesiredShardCount

func (*IndexConfig) GetNumberOfReplicas 

func (c *IndexConfig) GetNumberOfReplicas(def int) int

GetNumberOfReplicas returns the configured number_of_replicas, or def if unset/zero. Note: 0 replicas cannot be distinguished from "not set" because the int field with json:"omitempty" omits zero values. If zero-replica support is needed in the future, change the field type to *int. Currently 0 is treated as "use server default".

	VectorStoreID *string `json:"vector_store_id,omitempty"`
}

IndexDeletePayload represents the index delete task payload

	// Zero for keyword hits.
	VectorScore float64
	// Match type
	MatchType MatchType
	// IsEnabled
	IsEnabled bool
}

IndexWithScore represents the index with score

type IndexingStrategy 

type IndexingStrategy struct {
	// VectorEnabled enables semantic vector embedding and search
	VectorEnabled bool `yaml:"vector_enabled" json:"vector_enabled" extensions:"x-agent"`
	// KeywordEnabled enables keyword-based (BM25) search
	KeywordEnabled bool `yaml:"keyword_enabled" json:"keyword_enabled" extensions:"x-agent"`
	// WikiEnabled enables automatic wiki page generation from documents
	WikiEnabled bool `yaml:"wiki_enabled" json:"wiki_enabled" extensions:"x-agent"`
	// GraphEnabled enables knowledge graph entity/relation extraction
	GraphEnabled bool `yaml:"graph_enabled" json:"graph_enabled" extensions:"x-agent"`
}

func DefaultIndexingStrategy 

func DefaultIndexingStrategy() IndexingStrategy

DefaultIndexingStrategy returns the default strategy matching the legacy behavior: vector and keyword indexing enabled, wiki and graph disabled.

func (IndexingStrategy) HasAnyIndexing 

func (s IndexingStrategy) HasAnyIndexing() bool

HasAnyIndexing returns true if at least one indexing pipeline is enabled.

func (s IndexingStrategy) IsZero() bool

IsZero returns true if the strategy has no pipelines enabled (zero value).

func (IndexingStrategy) NeedsChunks 

func (s IndexingStrategy) NeedsChunks() bool

func (IndexingStrategy) NeedsEmbedding 

func (s IndexingStrategy) NeedsEmbedding() bool

NeedsEmbedding returns true if any pipeline that requires an embedding model is enabled.

func (*IndexingStrategy) Scan 

func (s *IndexingStrategy) Scan(value interface{}) error

Scan implements the sql.Scanner interface for GORM deserialization. When the database column is NULL (existing rows before migration), it returns DefaultIndexingStrategy() for backward compatibility.

func (IndexingStrategy) Value 

func (s IndexingStrategy) Value() (driver.Value, error)

Value implements the driver.Valuer interface for GORM serialization.

type InternalDispatch added in v0.9.0 

type InternalDispatch struct {
	UserID   string
	TenantID uint64
}

InternalDispatch is the identity an in-process API dispatch runs as. It is carried only on the Go context of a request constructed by the server itself, so no inbound HTTP request can present it. Auth rebuilds the full session (user, tenant membership, role) from the database instead of trusting anything else on the request.

func InternalDispatchFromContext added in v0.9.0 

func InternalDispatchFromContext(ctx context.Context) (InternalDispatch, bool)

InternalDispatchFromContext returns the in-process caller ctx was marked with.

type InviteMemberRequest 

type InviteMemberRequest struct {
	// TenantID is the workspace to enrol as an org member. Preferred field.
	TenantID uint64 `json:"tenant_id"`
	// RepresentativeUserID is accepted for compatibility and ignored: a
	// direct add attaches no user of the enrolled workspace, since the
	// inviter must not choose whose details the roster shows.
	RepresentativeUserID string `json:"representative_user_id"`
	// UserID is retained for backward compatibility. When set without
	// TenantID, the handler resolves the user's TenantID.
	UserID string        `json:"user_id"`
	Role   OrgMemberRole `json:"role" binding:"required"` // Role to assign: admin/editor/viewer
}

InviteMemberRequest represents a request to directly invite a workspace to an organization.

Plan 3 (#1303) moved membership to the workspace level: an invitation enrols a whole workspace into the organization. Callers SHOULD set TenantID. For backward compatibility with older SDK callers that still send UserID alone, the handler resolves that user's TenantID. No representative user is attached.

type JSON 

type JSON json.RawMessage

JSON is a custom type that wraps json.RawMessage. Used for storing JSON data in the database.

func PatchFAQAnswerStrategy 

func PatchFAQAnswerStrategy(dstMeta, srcMeta JSON) (JSON, error)

UnmarshalJSON implements the json.Unmarshaler interface.

func (JSON) Value 

func (j JSON) Value() (driver.Value, error)

Value implements the driver.Valuer interface.

type JSONMap 

type JSONMap map[string]any

JSONMap is a map[string]any that round-trips through Postgres JSONB columns via GORM. The standard library's database/sql doesn't know how to scan JSONB into a typed map, so we hand-roll Value() / Scan().

Lives here (not in /utils) because the only callers are types whose schemas already declare JSONB columns — keeping the helper next to its users avoids a circular import in any package that already pulls in /types.

func (*JSONMap) Scan 

func (m *JSONMap) Scan(src any) error

Scan implements sql.Scanner. Accepts both []byte (real JSONB) and string (some drivers under sqlmock); anything else is a programming error.

func (JSONMap) Value 

func (m JSONMap) Value() (driver.Value, error)

Value implements driver.Valuer. Returns nil when the map is nil so JSONB columns store SQL NULL instead of "null".

type JoinByOrganizationIDRequest 

type JoinByOrganizationIDRequest struct {
	OrganizationID string        `json:"organization_id" binding:"required"`
	Message        string        `json:"message" binding:"max=500"` // Optional message for join request
	Role           OrgMemberRole `json:"role"`                      // Optional: requested role (admin/editor/viewer); default viewer
}

	Email         string     `json:"email"`
	Message       string     `json:"message"`
	RequestType   string     `json:"request_type"`   // 'join' or 'upgrade'
	PrevRole      string     `json:"prev_role"`      // Previous role (only for upgrade requests)
	RequestedRole string     `json:"requested_role"` // Role the applicant requested (admin/editor/viewer)
	Status        string     `json:"status"`
	CreatedAt     time.Time  `json:"created_at"`
	ReviewedAt    *time.Time `json:"reviewed_at,omitempty"`

const (
	JoinRequestStatusPending  JoinRequestStatus = "pending"
	JoinRequestStatusApproved JoinRequestStatus = "approved"
	JoinRequestStatusRejected JoinRequestStatus = "rejected"
)

type JoinRequestType 

type JoinRequestType string

JoinRequestType represents the type of a join request 

const (
	// JoinRequestTypeJoin is for new member join requests
	JoinRequestTypeJoin JoinRequestType = "join"
	// JoinRequestTypeUpgrade is for role upgrade requests from existing members
	JoinRequestTypeUpgrade JoinRequestType = "upgrade"
)

type KBCapabilities 

type KBCapabilities struct {
	// Vector means semantic (embedding) search is indexed.
	Vector bool `json:"vector"`
	// Keyword means BM25 / sparse keyword search is indexed.
	Keyword bool `json:"keyword"`
	// Wiki means the wiki feature is enabled and authored pages exist / will be generated.
	Wiki bool `json:"wiki"`
	// Graph means knowledge-graph extraction is enabled.
	Graph bool `json:"graph"`
	// FAQ means the KB is a FAQ-type KB (Q/A pairs).
	FAQ bool `json:"faq"`
}

KBCapabilities describes the functional features a knowledge base exposes. It is computed from the KB's configuration (IndexingStrategy, Type, WikiConfig, …) and surfaced in the JSON representation of a KnowledgeBase so that the frontend can filter / enable / disable KB options based on what the selected agent type needs.

type KBClonePayload 

type KBClonePayload struct {
	TracingContext
	TenantID  uint64        `json:"tenant_id"`
	TaskID    string        `json:"task_id"`

KnowledgeBase represents a knowledge base entity

func (*KnowledgeBase) Capabilities 

func (kb *KnowledgeBase) Capabilities() KBCapabilities

Capabilities returns the computed capability flags for this KB. Safe to call on a nil KB (returns zero value).

func (*KnowledgeBase) EffectiveStorageProvider 

func (kb *KnowledgeBase) EffectiveStorageProvider(tenantDefault string) string

EffectiveStorageProvider returns the KB's storage provider, falling back to the supplied tenant default when the KB does not pin one. This mirrors the selection logic in resolveFileService and is used by clone preflight checks to detect cross-storage-backend clones (which are not supported).

func (*KnowledgeBase) EnsureDefaults 

func (kb *KnowledgeBase) EnsureDefaults()

EnsureDefaults 确保类型与配置具备默认值

func (*KnowledgeBase) GetStorageProvider 

func (kb *KnowledgeBase) GetStorageProvider() string

GetStorageProvider returns the effective storage provider for this KB. Priority: StorageProviderConfig (new) > StorageConfig.Provider (legacy cos_config).

func (*KnowledgeBase) HasVectorStore 

func (kb *KnowledgeBase) HasVectorStore() bool

HasVectorStore reports whether the KB is bound to a DB-managed VectorStore (as opposed to the tenant's env-store fallback).

Safe to call on a nil receiver (returns false). Mirrors the convention of other Is*Enabled / Capabilities accessors in this file.

func (*KnowledgeBase) IsGraphEnabled 

func (kb *KnowledgeBase) IsGraphEnabled() bool

IsGraphEnabled checks if knowledge graph extraction is enabled. Requires both the IndexingStrategy flag and a valid ExtractConfig.

func (*KnowledgeBase) IsImageVectorEnabled 

func (kb *KnowledgeBase) IsImageVectorEnabled() bool

IsImageVectorEnabled reports whether the knowledge base opted in to indexing and recalling images by their own vectors. The embedding model must also take images; callers check that separately, since it needs the model resolved.

func (*KnowledgeBase) IsKeywordEnabled 

func (kb *KnowledgeBase) IsKeywordEnabled() bool

IsKeywordEnabled checks if keyword (BM25) search is enabled.

func (*KnowledgeBase) IsMultimodalEnabled 

func (kb *KnowledgeBase) IsMultimodalEnabled() bool

IsMultimodalEnabled 判断多模态是否启用，由 VLMConfig.IsEnabled() 决定。

func (*KnowledgeBase) IsVectorEnabled 

func (kb *KnowledgeBase) IsVectorEnabled() bool

IsVectorEnabled checks if vector (semantic) search is enabled.

func (*KnowledgeBase) IsWikiEnabled 

func (kb *KnowledgeBase) IsWikiEnabled() bool

IsWikiEnabled checks if the wiki feature is enabled for this knowledge base. Wiki enablement is the single source of truth on IndexingStrategy.WikiEnabled.

func (*KnowledgeBase) MarshalJSON 

func (kb *KnowledgeBase) MarshalJSON() ([]byte, error)

MarshalJSON augments the default JSON encoding of KnowledgeBase with a computed `capabilities` field so clients (agent editor) can filter KBs by feature.

The legacy inline credentials (storage_config secret_id / secret_key and vlm_config api_key) are withheld. Their DB columns are written by StorageConfig.Value / VLMConfig.Value, so persistence is unaffected, while every JSON rendering of a KB is an API or tool response — including the lists shown to org-share receivers, who must never see the owner's keys. Clients only need these fields' presence, which /initialization/config reports separately.

func (*KnowledgeBase) NeedsEmbeddingModel 

func (kb *KnowledgeBase) NeedsEmbeddingModel() bool

NeedsEmbeddingModel returns true if any enabled pipeline requires an embedding model. Currently only vector and keyword search need embeddings.

func (*KnowledgeBase) Normalize 

func (kb *KnowledgeBase) Normalize()

Normalize folds the empty-string vector store id into nil so a single representation reaches both the DB and the retrieve-engine factory, which treats nil and `&""` as the same "no binding" signal. Idempotent and safe to call repeatedly.

Callers that accept unvalidated user input (CreateKnowledgeBase, async payload decoders) should invoke this before persistence or validation. Safe to call on a nil receiver (no-op).

func (*KnowledgeBase) SetStorageProvider 

func (kb *KnowledgeBase) SetStorageProvider(provider string)

SetStorageProvider writes the provider to the new StorageProviderConfig field.

func (*KnowledgeBase) SharesStorageBackendWith 

func (kb *KnowledgeBase) SharesStorageBackendWith(other *KnowledgeBase, defaultBackendID, defaultProvider string) bool

SharesStorageBackendWith compares concrete instance bindings first. Provider comparison is only a compatibility fallback for rows not yet backfilled.

func (*KnowledgeBase) SharesStoreWith 

func (kb *KnowledgeBase) SharesStoreWith(other *KnowledgeBase) bool

SharesStoreWith reports whether two knowledge bases are bound to the same vector store. Both env-fallback (nil) → true; both same UUID → true; otherwise false. Safe to call when either receiver or argument is nil (returns true iff both are nil).

Empty-string VectorStoreID is treated as equivalent to nil so that rows persisted by callers that did not run Normalize first (raw-SQL writes, external migrations, ops scripts) still compare correctly. The alternative — treating `&""` as a distinct binding — would reject otherwise valid CopyKnowledgeBase clones with a confusing "different vector stores" 400. This normalization is read-only; it does not mutate the receivers.

Lives on *KnowledgeBase next to HasVectorStore() so the binding semantics stay co-located with the type they describe.

func (*KnowledgeBase) UnmarshalJSON 

func (kb *KnowledgeBase) UnmarshalJSON(data []byte) error

UnmarshalJSON keeps backward compatibility for legacy clients that still send `cos_config` or `storage_config`, while migrating to `storage_provider_config`.

type KnowledgeBaseConfig 

type KnowledgeBaseConfig struct {
	// Chunking configuration
	ChunkingConfig ChunkingConfig `yaml:"chunking_config"         json:"chunking_config"`

}

KnowledgeBaseProfile is the generated knowledge-base description. The gist, topics and questions come from one small model call over the aggregate; the stats are copied from the aggregate so readers do not have to recompute it.

	Stats KnowledgeBaseProfileStats `json:"stats"`
	// SampleTitles is a stratified sample of document titles.
	SampleTitles []string `json:"sample_titles,omitempty"`
	// SampleQuestions is a sample of per-document typical questions, spread
	// across topics so one large topic does not crowd the others out.
	SampleQuestions []string `json:"sample_questions,omitempty"`
	// SampleGists is a small sample of per-document gists.
	SampleGists []string `json:"sample_gists,omitempty"`
	// Hash fingerprints the inputs; see BuildKnowledgeBaseProfileAggregate.
	Hash string `json:"hash"`
}

KnowledgeBaseProfileAggregate is the deterministic layer between documents and the generated description. Everything in it is a count or a sample, so deleting a document simply removes its contribution on the next build.

func BuildKnowledgeBaseProfileAggregate 

func BuildKnowledgeBaseProfileAggregate(rows []*KnowledgeProfileRow) *KnowledgeBaseProfileAggregate

BuildKnowledgeBaseProfileAggregate folds document rows into counts and samples. Rows are expected to be pre-filtered to eligible documents.

func (*KnowledgeBaseProfileAggregate) IsEmpty 

func (a *KnowledgeBaseProfileAggregate) IsEmpty() bool

IsEmpty reports whether no eligible document contributed.

type KnowledgeBaseProfileConfig 

type KnowledgeBaseProfileConfig struct {
	// Enabled turns the AI knowledge-base description on.
	Enabled bool `yaml:"enabled" json:"enabled" extensions:"x-agent=profile_enabled"`
	// ModelID overrides the summary model. Empty uses summary_model_id.
	ModelID string `yaml:"model_id,omitempty" json:"model_id,omitempty" extensions:"x-agent=profile_model_id"`
	// CustomInstructions is extra guidance for the description, such as the audience. The format stays fixed.
	CustomInstructions string `` /* 153-byte string literal not displayed */
}

KnowledgeBaseProfileConfig controls automatic generation of the knowledge base description. It is opt-in so upgrading a deployment adds no model calls.

func (*KnowledgeBaseProfileConfig) IsEnabled 

func (c *KnowledgeBaseProfileConfig) IsEnabled() bool

IsEnabled reports whether automatic generation is on for a nil-safe receiver.

func (*KnowledgeBaseProfileConfig) Scan 

func (c *KnowledgeBaseProfileConfig) Scan(value interface{}) error

Scan implements sql.Scanner.

func (KnowledgeBaseProfileConfig) Value 

func (c KnowledgeBaseProfileConfig) Value() (driver.Value, error)

Value implements driver.Valuer.

type KnowledgeBaseProfilePayload 

type KnowledgeBaseProfilePayload struct {

	Force           bool   `json:"force,omitempty"`
}

KnowledgeBaseProfilePayload asks the worker to rebuild the generated description of one knowledge base from its current document profiles. Force bypasses the aggregate-hash short circuit (manual regeneration).

type KnowledgeBaseProfileStats 

type KnowledgeBaseProfileStats struct {
	// DocumentCount is the number of eligible documents at generation time.
	DocumentCount int `json:"document_count"`
	// ProfiledCount is how many of them carried a document profile.
	ProfiledCount int `json:"profiled_count"`
	// FileTypes counts documents per file extension.
	FileTypes []NamedCount `json:"file_types,omitempty"`
	// Tags counts documents per knowledge-base tag.
	Tags []NamedCount `json:"tags,omitempty"`
	// RawTopics counts documents per normalized topic keyword before merging.
	RawTopics []NamedCount `json:"raw_topics,omitempty"`
	// DocTypes counts documents per model-assigned document type.
	DocTypes []NamedCount `json:"doc_types,omitempty"`
	// Folders lists the top-level folder names present.
	Folders []string `json:"folders,omitempty"`
	// EarliestAt and LatestAt bound document creation times.
	EarliestAt *time.Time `json:"earliest_at,omitempty"`
	LatestAt   *time.Time `json:"latest_at,omitempty"`
}

KnowledgeBaseProfileStats is the deterministic part of the profile: every number here comes from a database aggregation, never from a model.

type KnowledgeBaseShare 

type KnowledgeBaseShare struct {
	// Unique identifier
	ID string `json:"id" gorm:"type:varchar(36);primaryKey"`
	// Knowledge base ID being shared

}

KnowledgeFolderCount is one row of the folder aggregation query: the number of knowledge entries stored directly in a folder path.

type KnowledgeFolderNode 

type KnowledgeFolderNode struct {
	// Path is the canonical folder path, e.g. "docs/spec".
	Path string `json:"path" extensions:"x-agent=folder_path"`
	// Name is the last segment of Path, used as the tree row label.

	TotalCount int64 `json:"total_count" extensions:"x-agent"`
	// Children are the direct sub-folders, sorted by name.
	Children []*KnowledgeFolderNode `json:"children,omitempty"`
}

KnowledgeFolderNode is a node of the knowledge base folder tree exposed to clients. DocumentCount counts entries stored directly in this folder; TotalCount additionally counts every descendant folder's entries.

type KnowledgeFolderScope 

type KnowledgeFolderScope string

KnowledgeFolderScope selects how KnowledgeListFilter.FolderPath is applied. 

const (
	// FolderScopeAny ignores the folder dimension entirely (flat listing).
	FolderScopeAny KnowledgeFolderScope = ""
	// FolderScopeExact keeps only entries stored directly in FolderPath.
	FolderScopeExact KnowledgeFolderScope = "exact"
	// FolderScopeSubtree keeps entries in FolderPath and any descendant folder.
	FolderScopeSubtree KnowledgeFolderScope = "subtree"
)

type KnowledgeFolderTree

}

KnowledgeFolderTree is the response payload of the folder tree endpoint.

func BuildKnowledgeFolderTree 

func BuildKnowledgeFolderTree(counts []*KnowledgeFolderCount) *KnowledgeFolderTree

BuildKnowledgeFolderTree turns the flat per-folder counts returned by the repository into a tree. Intermediate folders that hold no documents of their own (only sub-folders) are materialized so the hierarchy stays connected.

	// unambiguously mean "the knowledge base root".
	FolderPath string
	// FolderScope selects whether FolderPath matches exactly or includes
	// descendant folders. FolderScopeAny (the default) ignores folders.
	FolderScope KnowledgeFolderScope
	// SortBy 指定列表排序字段；公开列表接口会显式提供默认值。
	SortBy KnowledgeListSortField
	// SortOrder 指定升序或降序；零值与 desc 等价。
	SortOrder KnowledgeListSortOrder
}

KnowledgeListFilter aggregates optional filters for listing knowledge entries under a knowledge base. Empty / zero fields mean "no filter on that dimension".

	KnowledgeID  string     `gorm:"column:knowledge_id"              json:"knowledge_id"`
	Attempt      int        `gorm:"column:attempt"                   json:"attempt"`
	SpanID       string     `gorm:"column:span_id;size:64"           json:"span_id"`
	ParentSpanID string     `gorm:"column:parent_span_id;size:64"    json:"parent_span_id,omitempty"`
	Name         string     `gorm:"column:name;size:255"             json:"name"`

	CreatedAt    time.Time  `gorm:"column:created_at;autoCreateTime" json:"created_at"`
	UpdatedAt    time.Time  `gorm:"column:updated_at;autoUpdateTime" json:"updated_at"`
}

KnowledgeProcessingSpan is one row in knowledge_processing_spans.

Field tags pull double duty: GORM (storage) and JSON (API). ErrorDetail is excluded by default — handlers must opt in for admin views, matching how the dead-letter middleware already protects raw stack traces.

func (KnowledgeProcessingSpan) TableName 

func (KnowledgeProcessingSpan) TableName() string

TableName pins the table because GORM's default pluralization ("knowledge_processing_spans") happens to match — explicit beats implicit.

type KnowledgeProfile 

type KnowledgeProfile struct {
	// Gist is a one-line statement of what the document is about.
	Gist string `json:"gist,omitempty"`
	// Topics lists 3-5 short topic keywords.
	Topics []string `json:"topics,omitempty"`
	// DocType is a coarse label such as "user manual", "meeting notes" or "contract".
	DocType string `json:"doc_type,omitempty"`
	// TypicalQuestion is one natural-language question this document answers.
	TypicalQuestion string `json:"typical_question,omitempty"`
}

KnowledgeProfile is the structured, per-document artifact produced next to the free-text summary. It is deliberately tiny: a headline, a handful of topic keywords, a document type and one question the document can answer. Knowledge-base level descriptions are derived from these rows, so every field here is something an aggregation can count or sample.

func (*KnowledgeProfile) Clone 

func (p *KnowledgeProfile) Clone() *KnowledgeProfile

Clone returns an independent copy (nil-safe) so a cloned document does not share the topic slice with its source.

func (*KnowledgeProfile) IsEmpty 

func (p *KnowledgeProfile) IsEmpty() bool

IsEmpty reports whether the profile carries no usable field.

func (*KnowledgeProfile) Normalize 

func (p *KnowledgeProfile) Normalize() *KnowledgeProfile

Normalize trims, deduplicates and bounds every field so model output of arbitrary shape becomes a stable, small record. It returns the receiver so callers can chain it, and nil when nothing survives.

func (*KnowledgeProfile) Scan 

func (p *KnowledgeProfile) Scan(value interface{}) error

Scan implements sql.Scanner.

func (KnowledgeProfile) Value 

func (p KnowledgeProfile) Value() (driver.Value, error)

Value implements driver.Valuer.

type KnowledgeProfileRow 

type KnowledgeProfileRow struct {
	ID         string            `json:"id"`
	Title      string            `json:"title"`
	FileName   string            `json:"file_name"`
	FileType   string            `json:"file_type"`
	FolderPath string            `json:"folder_path"`
	CreatedAt  time.Time         `json:"created_at"`
	Profile    *KnowledgeProfile `json:"profile,omitempty"`
	// Tags is populated by the aggregation from the tag relation table.
	Tags []string `json:"tags,omitempty"`
}

KnowledgeProfileRow is the lightweight projection of a knowledge row used by the knowledge-base aggregation. It deliberately omits content columns.

func (*KnowledgeProfileRow) DisplayTitle 

func (r *KnowledgeProfileRow) DisplayTitle() string

DisplayTitle returns the title, falling back to the file name.

type KnowledgeSearchOptions 

type KnowledgeSearchOptions struct {
	// VectorThreshold and KeywordThreshold override the recall thresholds.
	VectorThreshold  *float64
	KeywordThreshold *float64
	// MatchCount is the number of results to return.
	MatchCount           int
	DisableKeywordsMatch bool
	DisableVectorMatch   bool
	// Rerank overrides the rerank stage. Nil reranks with the tenant config.
	Rerank *RerankOptions
}

KnowledgeSearchOptions are the caller overrides accepted by the knowledge-search API. Zero values keep the tenant RetrievalConfig.

type KnowledgeSearchScope 

type KnowledgeSearchScope struct {
	TenantID uint64
	KBID     string
}

KnowledgeSearchScope defines a (tenant_id, knowledge_base_id) scope for knowledge search (e.g. own KBs + shared KBs).

type KnowledgeTag 

type KnowledgeTag struct {
	// Unique identifier of the tag (UUID)
	ID string `json:"id"                gorm:"type:varchar(36);primaryKey" extensions:"x-agent=tag_id"`
	// SeqID is an auto-increment integer ID for external API usage
	SeqID int64 `json:"seq_id"            gorm:"type:bigint;uniqueIndex;autoIncrement" extensions:"x-agent=tag_seq_id"`
	// Workspace ID
	TenantID uint64 `json:"tenant_id"`
	// Knowledge base ID that this tag belongs to
	KnowledgeBaseID string `json:"knowledge_base_id" gorm:"type:varchar(36);index"`
	// Tag name, unique within the same knowledge base
	Name string `json:"name"              gorm:"type:varchar(128);not null" extensions:"x-agent"`
	// Optional display color
	Color string `json:"color"             gorm:"type:varchar(32)"`
	// Sort order within the same knowledge base
	SortOrder int `json:"sort_order"        gorm:"default:0"`
	// Creation time
	CreatedAt time.Time `json:"created_at"`
	// Last updated time
	UpdatedAt time.Time `json:"updated_at"`
}

KnowledgeTag represents a tag (category) under a specific knowledge base. Tags are scoped by knowledge base (and tenant) and are used to categorize Knowledge (documents) and FAQ Chunks.

func (*KnowledgeTag) BeforeCreate 

func (t *KnowledgeTag) BeforeCreate(tx *gorm.DB) error

BeforeCreate ensures SeqID is populated for databases that don't support autoIncrement on non-primary-key columns (e.g. SQLite). On PostgreSQL/MySQL the DB sequence handles this, so we skip to avoid duplicate key races under concurrent inserts.

	// Function.Arguments is decoded to durable application identifiers before
	// tool execution. These fields must never be sent back to a provider or
	// persisted in chat history.
	ModelArguments     string   `json:"-"`
	ArgumentResolution string   `json:"-"`
	UnresolvedHandles  []string `json:"-"`
}

LLMToolCall represents a function/tool call from the LLM

type LangfuseTracingCarrier 

type LangfuseTracingCarrier interface {
	SetLangfuseTracing(TracingContext)
	GetLangfuseTracing() TracingContext
}

LangfuseTracingCarrier is implemented automatically by any struct that embeds TracingContext (thanks to Go's method promotion rules). The asynq enqueue helper in internal/tracing/langfuse uses this interface to inject the current trace/span ids into the payload without caring about the concrete payload type.

type ListJoinRequestsResponse 

type ListJoinRequestsResponse struct {
	Requests []JoinRequestResponse `json:"requests"`
	Total    int64                 `json:"total"`
}

	User    *User  `json:"user,omitempty"`
	// ActiveTenant is the workspace whose ID is encoded in the issued JWT;
	// future requests are scoped to it until the client calls /auth/switch-tenant.
	// Defaults to the user's home workspace on a fresh login.
	ActiveTenant *Tenant `json:"active_tenant,omitempty"`
	// Memberships lists every workspace the user can authenticate into,
	// along with their role in each. Always populated (length 1 for users
	// who only belong to their home workspace) so frontends can render a
	// workspace switcher without a follow-up request. Serialised without
	// omitempty so the field is always present as a JSON array (possibly
	// empty) — the "always populated" contract relies on the server side
	// guaranteeing a non-nil slice.
	Memberships  []Membership `json:"memberships"`
	Token        string       `json:"token,omitempty"`
	RefreshToken string       `json:"refresh_token,omitempty"`

Scan implements sql.Scanner interface for MCPAdvancedConfig

func (*MCPAdvancedConfig) Value 

func (c *MCPAdvancedConfig) Value() (driver.Value, error)

Value implements driver.Valuer interface for MCPAdvancedConfig

type MCPAuthConfig 

type MCPAuthConfig struct {
	// AuthType selects the authentication strategy. Empty ("") is treated as
	// none for backward compatibility with rows that pre-date this field.
	AuthType MCPAuthType `json:"auth_type,omitempty"`
	APIKey   string      `json:"api_key,omitempty"`
	// APIKeyHeader is the header name that carries APIKey when AuthType is
	// api_key. Empty defaults to "X-API-Key". This is non-secret structural
	// config (the secret is APIKey), so it is not encrypted and is safe to echo
	// back in responses. It lets services that expect the key in a different
	// header (e.g. the raw token directly in "Authorization") work without
	// resorting to plaintext custom headers.
	APIKeyHeader  string            `json:"api_key_header,omitempty"`
	Token         string            `json:"token,omitempty"`
	CustomHeaders map[string]string `json:"custom_headers,omitempty"`
	// Scopes are the OAuth scopes requested during authorization. Optional.
	Scopes []string `json:"scopes,omitempty"`
	// AuthServerMetadataURL optionally pins the OAuth authorization server
	// metadata URL. When empty, the server is discovered automatically from
	// the MCP URL (RFC 9728 / RFC 8414).
	AuthServerMetadataURL string `json:"auth_server_metadata_url,omitempty"`
	// ClientID optionally names an OAuth client registered with the
	// authorization server in advance. When set it is used instead of dynamic
	// client registration, for servers that offer no registration endpoint or
	// allow grants only to clients an administrator registered. Non-secret.
	ClientID string `json:"client_id,omitempty"`
	// ClientSecret is the secret of ClientID for a confidential client.
	// Secret: encrypted at rest like APIKey and Token, never returned, and
	// changed only through the credentials subresource after creation.
	ClientSecret string `json:"client_secret,omitempty"`
}

MCPAuthConfig represents authentication configuration for MCP service.

Secret fields (APIKey, Token) are persisted in this struct but are NEVER returned through main resource responses — those go through dto.MCPServiceResponse which omits them by construction. Credential mutations happen through the dedicated /credentials subresource handled by MCPCredentialsHandler.

OAuth note: the OAuth strategy stores no secret in this struct. The per-user access/refresh tokens live in mcp_oauth_tokens and the dynamically registered client lives in mcp_oauth_clients. The fields here (Scopes, AuthServerMetadataURL) are non-secret OAuth configuration.

func (*MCPAuthConfig) IsOAuth 

func (c *MCPAuthConfig) IsOAuth() bool

IsOAuth reports whether this service uses the OAuth strategy.

func (*MCPAuthConfig) Scan 

func (c *MCPAuthConfig) Scan(value interface{}) error

Scan implements sql.Scanner for MCPAuthConfig.

Legacy plaintext rows (no enc:v1: prefix) are returned as-is; encrypted rows are decrypted. DecryptStoredSecret fails loudly if the prefix is present but SYSTEM_AES_KEY is missing/rotated, so we surface that as a Scan error rather than letting ciphertext leak upstream as the API key.

func (*MCPAuthConfig) Value 

func (c *MCPAuthConfig) Value() (driver.Value, error)

Value implements driver.Valuer for MCPAuthConfig.

When SYSTEM_AES_KEY is configured, APIKey, Token and ClientSecret are AES-256-GCM encrypted before serialization — mirroring the ModelParameters / WebSearchProviderParameters pattern so MCP secrets are not the odd resource stored in plaintext. Encryption operates on a local copy to avoid mutating the caller's in-memory struct (subsequent reads of the same *MCPAuthConfig would otherwise see ciphertext).

type MCPAuthType 

type MCPAuthType string

MCPAuthType enumerates the authentication strategies for an MCP service. 

const (
	// MCPAuthNone means no authentication (or only static custom headers).
	MCPAuthNone MCPAuthType = ""
	// MCPAuthAPIKey injects a static API key header (X-API-Key).
	MCPAuthAPIKey MCPAuthType = "api_key"
	// MCPAuthBearer injects a static Authorization: Bearer <token> header.
	MCPAuthBearer MCPAuthType = "bearer"
	// MCPAuthOAuth performs the MCP OAuth2 authorization-code flow
	// (discovery + dynamic client registration + PKCE) per user. Tokens are
	// stored per (tenant, user, service) in mcp_oauth_tokens.
	MCPAuthOAuth MCPAuthType = "oauth"
)

type MCPEndpoint 

type MCPEndpoint struct {

	TokenHash string `json:"-" gorm:"type:varchar(64);not null;default:'';uniqueIndex:idx_mcp_endpoints_token_hash"`
	// TokenHint is the first few characters of the token so the UI can show
	// "mcp_ab12…" next to an endpoint without revealing the secret.
	TokenHint string `json:"token_hint" gorm:"type:varchar(16);not null;default:''"`
	// KnowledgeBaseIDs bounds every knowledge-facing tool. Empty means every
	// knowledge base the workspace owns or has been granted at call time.
	KnowledgeBaseIDs StringArray `json:"knowledge_base_ids" gorm:"type:jsonb;not null;default:'[]'"`
	// Tools is the allowlist of MCP tool names this endpoint exposes. Names
	// must come from the MCP endpoint tool catalog; unknown names are dropped
	// on write.
	Tools StringArray `json:"tools" gorm:"type:jsonb;not null;default:'[]'"`
	// DefaultAgentID is the agent used by the ask tool when the caller does
	// not name one. Empty falls back to the workspace's builtin agent.
	DefaultAgentID     string         `json:"default_agent_id"      gorm:"type:varchar(36);not null;default:''"`
	RateLimitPerMinute int            `json:"rate_limit_per_minute" gorm:"not null;default:60"`

	CreatedAt          time.Time      `json:"created_at"`
	UpdatedAt          time.Time      `json:"updated_at"`
	DeletedAt          gorm.DeletedAt `json:"deleted_at" gorm:"index"`
}

MCPEndpoint is one workspace-owned MCP server surface that external MCP clients (Claude Desktop, Cursor, VS Code Copilot, ...) can connect to over Streamable HTTP. A workspace may publish any number of endpoints; each one carries its own bearer token, knowledge-base scope and tool allowlist, so a single WeKnora deployment can serve several narrowly scoped MCP servers without running a separate process per workspace.

The endpoint is the unit of trust: everything a connected client may do is derived from this row (see MCPEndpointScope), and the token authenticates the endpoint rather than a person.

func (*MCPEndpoint) AllowsKnowledgeBase 

func (e *MCPEndpoint) AllowsKnowledgeBase(kbID string) bool

AllowsKnowledgeBase reports whether kbID is inside the endpoint scope. An endpoint without an allowlist admits every knowledge base; ownership is still checked by the knowledge services.

func (*MCPEndpoint) BeforeCreate 

func (e *MCPEndpoint) BeforeCreate(_ *gorm.DB) error

BeforeCreate assigns the id and fills defaults before insert.

func (*MCPEndpoint) HasTool 

func (e *MCPEndpoint) HasTool(name string) bool

HasTool reports whether the endpoint exposes the named tool.

func (*MCPEndpoint) RestrictsKnowledgeBases 

func (e *MCPEndpoint) RestrictsKnowledgeBases() bool

RestrictsKnowledgeBases reports whether the endpoint pins an explicit knowledge-base allowlist rather than inheriting the whole workspace.

func (MCPEndpoint) TableName 

func (MCPEndpoint) TableName() string

TableName returns the storage table.

type MCPEndpointToolDefinition 

type MCPEndpointToolDefinition struct {
	Name  string               `json:"name"`
	Group MCPEndpointToolGroup `json:"group"`
	// Destructive marks tools that mutate or delete workspace content; the UI
	// leaves them unchecked by default and the server requires the ingest
	// capability for them.
	Destructive bool `json:"destructive"`
}

MCPEndpointToolCatalog returns a copy of the ordered tool catalog.

type MCPEndpointToolGroup 

type MCPEndpointToolGroup string

MCPEndpointToolGroup partitions the endpoint tool catalog by the kind of access a tool needs. Groups map onto tenant API key capabilities so the same route/scope checks that guard the REST API also bound MCP tools. 

const (
	MCPEndpointToolGroupRetrieve MCPEndpointToolGroup = "retrieve"
	MCPEndpointToolGroupChat     MCPEndpointToolGroup = "chat"
	MCPEndpointToolGroupWiki     MCPEndpointToolGroup = "wiki"

	Stale             bool       `json:"stale"              gorm:"-" extensions:"x-agent"`
}

MCPMetadata is a complete, explicitly synchronized directory. OAuth snapshots are scoped to the authorizing principal; they must never become tenant-wide.

func (MCPMetadata) TableName 

func (MCPMetadata) TableName() string

TableName returns the directory snapshot table.

type MCPMetadataSummary 

type MCPMetadataSummary struct {
	ServiceID         string    `gorm:"column:service_id"`

	SyncedAt          time.Time `gorm:"column:synced_at"`
	ServerName        string    `gorm:"column:server_name"`
}

MCPMetadataSummary is the list-card view of a snapshot: counts only, no tool payloads.

type MCPOAuthClient 

type MCPOAuthClient struct {
	ID           string    `json:"id"            gorm:"type:varchar(36);primaryKey"`
	TenantID     uint64    `json:"tenant_id"     gorm:"not null;uniqueIndex:idx_mcp_oauth_clients_tenant_svc"`
	ServiceID    string    `json:"service_id"    gorm:"type:varchar(36);not null;uniqueIndex:idx_mcp_oauth_clients_tenant_svc;index"`
	ClientID     string    `json:"client_id"     gorm:"type:varchar(512);not null"`

	CreatedAt    time.Time `json:"created_at"`
	UpdatedAt    time.Time `json:"updated_at"`
}

MCPOAuthClient stores the OAuth client credentials obtained for an MCP service. For servers that support RFC 7591 Dynamic Client Registration the client_id (and optional client_secret) is registered once per service and reused across all users of that service, avoiding a registration round-trip on every authorization.

One row per (tenant_id, service_id). The client_secret is encrypted at rest (AES-256-GCM) when SYSTEM_AES_KEY is configured.

func (*MCPOAuthClient) AfterFind 

func (m *MCPOAuthClient) AfterFind(tx *gorm.DB) error

AfterFind decrypts the client secret after loading.

func (*MCPOAuthClient) BeforeCreate

BeforeCreate sets the primary key and encrypts the client secret.

func (*MCPOAuthClient) BeforeSave 

func (m *MCPOAuthClient) BeforeSave(tx *gorm.DB) error

BeforeSave re-encrypts the secret on update paths.

func (MCPOAuthClient) TableName 

func (MCPOAuthClient) TableName() string

TableName pins the table name. GORM's default naming would otherwise turn "MCPOAuthClient" into "mcpo_auth_clients" (treating "MCPO" as one token), which does not match the migration table "mcp_oauth_clients".

type MCPOAuthPromptRequest added in v0.9.0 

type MCPOAuthPromptRequest struct {
	ServiceID   string `json:"service_id"`
	ServiceName string `json:"service_name"`

	TokenType     string    `json:"token_type"    gorm:"type:varchar(32)"`
	ExpiresAt     time.Time `json:"expires_at"`
	// RefreshLeaseID / RefreshLeaseUntil coordinate refresh-token rotation
	// across application instances. They are operational fields only and are
	// never exposed through the API.

	RefreshLeaseUntil *time.Time `json:"-"`
	CreatedAt         time.Time  `json:"created_at"`
	UpdatedAt         time.Time  `json:"updated_at"`
}

MCPOAuthToken stores a per-principal OAuth token for an MCP service. The agent connects to the MCP server on behalf of the invoking principal, so tokens are isolated by (tenant_id, principal_type, principal_id, service_id).

AccessToken and RefreshToken are encrypted at rest (AES-256-GCM) when SYSTEM_AES_KEY is configured.

func (*MCPOAuthToken) AfterFind 

func (m *MCPOAuthToken) AfterFind(tx *gorm.DB) error

AfterFind decrypts secrets after loading.

func (*MCPOAuthToken) BeforeCreate 

func (m *MCPOAuthToken) BeforeCreate(tx *gorm.DB) error

	CreatedAt    time.Time `json:"created_at"`
	UpdatedAt    time.Time `json:"updated_at"`
}

MCPToolApproval persists per-tool policies for an MCP service, including whether the tool is enabled and whether calls require human approval. The tool list itself comes from MCP ListTools; this table stores overrides.

func (*MCPToolApproval) BeforeCreate 

func (m *MCPToolApproval) BeforeCreate(tx *gorm.DB) error

BeforeCreate sets ID for MCPToolApproval.

type MCPToolPolicyPatch 

type MCPToolPolicyPatch struct {

	// Risk sets the explicit risk; an empty string clears it.
	Risk *string
	// ObservedRisk records a risk the service declared.
	ObservedRisk *string
}

MCPToolPolicyPatch is a partial per-tool policy update. Nil fields are left unchanged on existing rows. A newly inserted row uses RequireApproval=false and Enabled=true for any omitted field.

type MCPTransportType string

MCPTransportType represents the transport type for MCP service 

const (
	MCPTransportSSE            MCPTransportType = "sse"             // Server-Sent Events
	MCPTransportHTTPStreamable MCPTransportType = "http-streamable" // HTTP Streamable

type ManualKnowledgePayload 

type ManualKnowledgePayload struct {
	// Document title.
	Title string `json:"title" extensions:"x-agent"`

	ChunkID         string `json:"chunk_id"`
	KnowledgeBaseID string `json:"knowledge_base_id"`
	URL             string `json:"url"`
}

MatchedImage retains an image vector hit's identity before context expansion replaces ImageInfo with all images in a surrounding text chunk.

type Membership 

type Membership struct {
	TenantID   uint64     `json:"tenant_id"`
	TenantName string     `json:"tenant_name"`
	Role       TenantRole `json:"role"`
}

Membership is the login-response-friendly projection of a TenantMember joined with tenant name. Returned as part of LoginResponse so the frontend can render a tenant switcher and gate UI by role.

type MemoryConfig 

type MemoryConfig struct {
	// Enabled defaults to false. Memory retains user statements across
	// sessions, so a workspace admin has to turn it on deliberately.
	Enabled bool `json:"enabled"`
	// WriteMode is MemoryWriteExplicitOnly or MemoryWriteAuto.
	WriteMode string `json:"write_mode"`
	// ExtractModelID is the model used by the background extraction task.
	// Empty means "use the model the conversation itself used", which is what
	// the settings UI promises, so the extraction task must never fail merely
	// because this is blank.
	ExtractModelID string `json:"extract_model_id"`
	// MaxItems caps active items per subject. 0 means DefaultMemoryMaxItems.
	MaxItems int `json:"max_items"`
	// ExtractDelaySeconds is how long a finished turn waits before
	// distillation runs. Waiting lets one model call cover the several
	// messages a user usually sends in a row. 0 means the default.
	ExtractDelaySeconds int `json:"extract_delay_seconds"`
	// ExtractMinIntervalSeconds is the floor between two distillation runs for
	// the same person, and exists purely to bound cost. It never drops a turn:
	// a turn arriving inside the interval is queued and picked up by the next
	// run. 0 means the default.
	ExtractMinIntervalSeconds int `json:"extract_min_interval_seconds"`
	// ExtractInstructions are workspace-specific rules appended to the
	// distillation prompt, for policies the product cannot guess ("never record
	// customer names", "always note the environment a question is about").
	ExtractInstructions string `json:"extract_instructions"`
	// InterestThreshold is how many separate conversations must touch a topic
	// before it becomes a stored interest. 0 means the default. Setting it to 1
	// records every topic on first sight, which is usually too noisy.
	InterestThreshold int `json:"interest_threshold"`
	// EmbeddingModelID is the single model used to score memory against a
	// question. It is pinned per workspace: knowledge bases each have their
	// own embedding model, and grabbing whichever one happens to be listed
	// first would mix incomparable vector spaces. Blank means semantic recall
	// is off and matching stays lexical.
	EmbeddingModelID string `json:"embedding_model_id"`
	// VectorRecall adds semantic similarity to memory recall. Nil means on
	// when an embedding model is reachable.
	//
	// Lexical matching alone cannot find a memory the user has re-worded, which
	// is most of them: "回答直接给结论" and "别铺垫那么多" share no tokens. The
	// cost is one embedding call per turn, bounded and degraded to lexical on
	// failure, so the feature never becomes a reason a chat is slow.
	VectorRecall *bool `json:"vector_recall"`
	// RetrievalConditioning lets memory shape retrieval — query rewriting and
	// per-document ranking — rather than only being appended to the answer
	// prompt. This is where memory earns its keep in a knowledge-base product.
	RetrievalConditioning *bool `json:"retrieval_conditioning"`
}

MemoryConfig is the workspace-level memory switch, stored as JSONB on tenants. It is deliberately small: everything a workspace admin can decide fits in four fields.

func (*MemoryConfig) AutoExtractEnabled 

func (c *MemoryConfig) AutoExtractEnabled() bool

AutoExtractEnabled reports whether the background distillation task should run. A nil or disabled config never extracts.

func (*MemoryConfig) EffectiveInterestThreshold 

func (c *MemoryConfig) EffectiveInterestThreshold() int

EffectiveInterestThreshold returns the promotion threshold for a nil config.

func (*MemoryConfig) EffectiveMaxItems 

func (c *MemoryConfig) EffectiveMaxItems() int

EffectiveMaxItems returns the active-item cap for a possibly nil config.

func (*MemoryConfig) ExtractDelay 

func (c *MemoryConfig) ExtractDelay() time.Duration

ExtractDelay is the debounce window for a possibly nil config.

func (*MemoryConfig) ExtractMinInterval 

func (c *MemoryConfig) ExtractMinInterval() time.Duration

ExtractMinInterval is the floor between two runs for a possibly nil config.

func (*MemoryConfig) MemoryEnabled 

func (c *MemoryConfig) MemoryEnabled() bool

MemoryEnabled reports whether the workspace switch is on.

func (*MemoryConfig) Normalize 

func (c *MemoryConfig) Normalize()

Normalize applies defaults and rejects unknown write modes.

func (*MemoryConfig) RetrievalConditioningEnabled 

func (c *MemoryConfig) RetrievalConditioningEnabled() bool

RetrievalConditioningEnabled reports whether memory may shape retrieval. Nil means on: a memory feature that cannot improve retrieval is most of the value left on the table in a knowledge-base product.

func (*MemoryConfig) Scan 

func (c *MemoryConfig) Scan(value interface{}) error

func (MemoryConfig) Value 

func (c MemoryConfig) Value() (driver.Value, error)

func (*MemoryConfig) VectorRecallEnabled 

func (c *MemoryConfig) VectorRecallEnabled() bool

VectorRecallEnabled reports whether recall may use semantic similarity.

type MemoryConsolidationResult 

type MemoryConsolidationResult struct {
	Merged  int `json:"merged"`
	Demoted int `json:"demoted"`
	Expired int `json:"expired"`
	// Reviewed is how many active memories the pass looked at.
	Reviewed int `json:"reviewed"`
	// Candidates is how many groups were put in front of the model.
	Candidates int `json:"candidates"`
	// Skipped is why nothing was merged, empty when something was.
	Skipped string `json:"skipped,omitempty"`
}

MemoryConsolidationResult is what a whole-store review did. Zeroes mean the store was already tidy, not that the review failed — Skipped says which.

type MemoryDocAffinity 

type MemoryDocAffinity struct {
	ID              string    `json:"id"         gorm:"primaryKey;type:varchar(36)"`
	TenantID        uint64    `json:"tenant_id"  gorm:"not null;uniqueIndex:idx_mem_affinity_scope,priority:1"`
	SubjectID       string    `json:"subject_id" gorm:"type:varchar(512);not null;uniqueIndex:idx_mem_affinity_scope,priority:2"`
	KnowledgeID     string    `json:"knowledge_id" gorm:"type:varchar(36);not null;uniqueIndex:idx_mem_affinity_scope,priority:3"`
	KnowledgeBaseID string    `json:"knowledge_base_id" gorm:"type:varchar(36);not null;default:''"`
	Title           string    `json:"title"      gorm:"type:varchar(512);not null;default:''"`
	Hits            int       `json:"hits"       gorm:"not null;default:0"`
	LastUsedAt      time.Time `json:"last_used_at" gorm:"column:last_used_at"`
	CreatedAt       time.Time `json:"created_at"`
	UpdatedAt       time.Time `json:"updated_at"`
}

MemoryDocAffinity records how often one person's answers drew on a document.

It is the only per-person retrieval signal we have that does not require asking them anything, and it is deliberately a plain counter rather than a graph: the previous attempt at this built an anchor table with four consumers that all filtered it out, so the rule now is that this table ships with the code that reads it or not at all.

func (MemoryDocAffinity) TableName 

func (MemoryDocAffinity) TableName() string

type MemoryDocView 

type MemoryDocView struct {
	ID              string    `json:"id"`
	KnowledgeID     string    `json:"knowledge_id"`
	KnowledgeBaseID string    `json:"knowledge_base_id"`
	Title           string    `json:"title"`
	Hits            int       `json:"hits"`
	LastUsedAt      time.Time `json:"last_used_at"`
}

MemoryDocView is a document this person keeps drawing answers from.

func MemoryDocViewFromAffinity 

func MemoryDocViewFromAffinity(row *MemoryDocAffinity) *MemoryDocView

MemoryDocViewFromAffinity projects a stored counter into the manager shape.

type MemoryExtractPayload 

type MemoryExtractPayload struct {
	TracingContext
	TenantID  uint64 `json:"tenant_id"`
	SubjectID string `json:"subject_id"`
	SessionID string `json:"session_id"`
	// MessageID is the assistant message that closed the triggering turn. It
	// bounds the extraction window and is stored as the source of any item
	// produced, so every memory can be traced back to a real message.
	MessageID string `json:"message_id"`
	// ChatModelID is the model the conversation itself used. The extraction
	// task falls back to it when MemoryConfig.ExtractModelID is blank, which
	// is what the settings UI promises.
	ChatModelID string `json:"chat_model_id,omitempty"`
	Language    string `json:"language,omitempty"`
}

MemoryExtractPayload carries everything the background distillation task needs. Scope (tenant + subject) travels in the payload rather than being read from the worker context: asynq and the Lite executor both start from a bare context, so anything the request knew and the payload does not carry is simply gone by the time the handler runs.

type MemoryExtractionBatch 

type MemoryExtractionBatch struct {
	// RetryAt keeps a redelivered task alive while a crashed worker's lease expires.
	RetryAt  time.Time
	Sessions []MemoryExtractionSession
}

type MemoryExtractionSession 

type MemoryExtractionSession struct {
	TenantID     uint64              `json:"-" gorm:"primaryKey;autoIncrement:false"`
	SubjectID    string              `json:"-" gorm:"primaryKey;type:varchar(512)"`
	SessionID    string              `json:"-" gorm:"primaryKey;type:varchar(36)"`
	Revision     uint64              `json:"revision" gorm:"not null;default:0"`

	Pending      bool                `json:"-" gorm:"not null;default:false"`
	FailureCount int                 `json:"-" gorm:"not null;default:0"`
	FailureCode  string              `json:"-" gorm:"type:varchar(64);not null;default:''"`
	FailedFrom   MemoryMessageCursor `json:"-" gorm:"embedded;embeddedPrefix:failed_from_"`
	FailedTo     MemoryMessageCursor `json:"-" gorm:"embedded;embeddedPrefix:failed_to_"`
	FailedAt     *time.Time          `json:"-"`
	UpdatedAt    time.Time           `json:"-"`
}

MemoryExtractionSession is a small indexed row, not an entry in a growing subject JSON document. Completed cursors prevent historical re-extraction.

func (MemoryExtractionSession) TableName 

func (MemoryExtractionSession) TableName() string

TableName selects the indexed session progress table.

type MemoryExtractionState 

type MemoryExtractionState struct {
	LeaseID    string    `json:"lease_id,omitempty"`
	LeaseUntil time.Time `json:"lease_until,omitempty"`
}

MemoryExtractionState contains only the subject-wide worker lease. Cursors and queued work live in MemoryExtractionSession.

func (*MemoryExtractionState) Scan 

func (s *MemoryExtractionState) Scan(value interface{}) error

func (MemoryExtractionState) Value 

func (s MemoryExtractionState) Value() (driver.Value, error)

type MemoryItem 

type MemoryItem struct {

	Topic string `json:"topic" gorm:"type:varchar(255);not null;default:''"`
	// NormalizedKey identifies the topic this item is about. A new item with

}

MemoryItem is a single remembered statement.

func (MemoryItem) TableName 

func (MemoryItem) TableName() string

type MemoryItemEmbedding 

type MemoryItemEmbedding struct {
	// Input snapshot prevents a slow embedding call from overwriting a newer edit.
	SourceContent string `json:"-" gorm:"-"`
	SourceTopic   string `json:"-" gorm:"-"`
	ItemID        string `json:"item_id"   gorm:"primaryKey;type:varchar(36)"`

	Dims    int    `json:"dims"     gorm:"not null;default:0"`

	CreatedAt time.Time `json:"created_at"`
	UpdatedAt time.Time `json:"updated_at"`
}

MemoryItemEmbedding is the vector for one memory, kept in its own table.

Separate from memory_items on purpose: the manager, the resident block and capacity enforcement all list items constantly, and none of them want to drag a few kilobytes of float per row along for the ride. Only the code that actually scores similarity loads these.

func (MemoryItemEmbedding) TableName 

func (MemoryItemEmbedding) TableName() string

type MemoryMessageCursor 

type MemoryMessageCursor struct {
	At time.Time `json:"at"`
	ID string    `json:"id"`
}

MemoryMessageCursor breaks timestamp ties using the message primary key.

func (MemoryMessageCursor) After 

func (c MemoryMessageCursor) After(other MemoryMessageCursor) bool

type MemoryPendingSessions 

type MemoryPendingSessions []string

MemoryPendingSessions is the persisted queue of sessions awaiting distillation for one subject.

func (MemoryPendingSessions) Append 

func (p MemoryPendingSessions) Append(sessionID string) MemoryPendingSessions

Append adds a session id without dropping existing work.

func (*MemoryPendingSessions) Scan 

func (p *MemoryPendingSessions) Scan(value interface{}) error

func (MemoryPendingSessions) Value 

func (p MemoryPendingSessions) Value() (driver.Value, error)

type MemorySettings 

type MemorySettings struct {
	// WorkspaceEnabled is the admin switch on the workspace.
	WorkspaceEnabled bool `json:"workspace_enabled"`
	// UserEnabled is the caller's own opt out. Meaningless while the
	// workspace switch is off, but still reported so the toggle keeps its
	// position when an admin turns the workspace back on.
	UserEnabled bool `json:"user_enabled"`
	// Effective is what actually happens: WorkspaceEnabled && UserEnabled.
	Effective bool `json:"effective"`
	// WriteMode is the workspace write mode.
	WriteMode string `json:"write_mode"`
	// ItemCount is how many active memories the caller currently has.
	ItemCount int `json:"item_count"`
	// MaxItems is the capacity cap after which the lowest ranked are archived.
	MaxItems int `json:"max_items"`
}

MemorySettings is the effective, already-merged memory state for one user. The UI renders this directly rather than merging a workspace setting with a user setting itself, so "why is my memory off" has exactly one answer.

type MemorySubject 

type MemorySubject struct {
	ID string `json:"id" gorm:"primaryKey;type:varchar(36)"`

	ExtractScheduledAt *time.Time `json:"extract_scheduled_at" gorm:"column:extract_scheduled_at"`
	// ConsolidatedAt is when this subject's memories were last reviewed as a

	// ForcedConsolidatedAt is when this person last asked for a review

MemorySubject is one memory space: a single principal inside a single workspace. Scope is always derived from the request context, never from a client-supplied id.

	SourceMessageID string    `json:"source_message_id" gorm:"column:source_message_id;type:varchar(36);index"`
	CreatedAt       time.Time `json:"created_at"`
}

MemoryTombstone records that a statement was deliberately forgotten, so the background distillation cannot quietly re-add it the next time it reads the message it came from.

It stores the topic and a fingerprint, never the statement. The trade-off is explicit: a re-worded restatement can come back, and that is the price of not retaining what the user asked us to drop.

func (MemoryTombstone) TableName() string

type MemoryTopicAliases 

type MemoryTopicAliases []string

MemoryTopicAliases is the list of surface forms that resolved to one topic.

}

MemoryTopicStat counts how often one person has asked about a topic.

A single question is noise; the same subject across several conversations is a signal. Counting first and promoting at a threshold is how MemoryOS keeps interest tracking from filling a profile with every passing question, and it is the reason a knowledge-base question can produce memory at all without producing a memory every time.

type MemoryTopicView 

type MemoryTopicView struct {
	ID         string    `json:"id"`

	Hits       int       `json:"hits"`
	Threshold  int       `json:"threshold"`
	LastSeenAt time.Time `json:"last_seen_at"`
}

MemoryTopicView is the topic-counter shape shown in the memory manager. Tenant and subject stay off the wire: the row is already scoped to the caller, and those ids are not something the UI should have to ignore.

func MemoryTopicViewFromStat 

func MemoryTopicViewFromStat(stat *MemoryTopicStat, threshold int) *MemoryTopicView

MemoryTopicViewFromStat projects a stored counter into the manager shape.

type MentionedItem 

type MentionedItem struct {

Message represents a conversation message Each message belongs to a conversation session and can be from either user or system Messages can contain references to knowledge chunks used to generate responses

func (*Message) BeforeCreate 

func (m *Message) BeforeCreate(tx *gorm.DB) (err error)

BeforeCreate is a GORM hook that runs before creating a new message record Automatically generates a UUID for new messages and initializes knowledge references Parameters:

  • tx: GORM database transaction

Returns:

  • error: Any error encountered during the hook execution

type MessageArtifact 

type MessageArtifact struct {
	URL         string    `json:"url"`                    // Storage URL (provider://path); persisted, not sent to client
	FileName    string    `json:"file_name"`              // Original filename inside the sandbox

	// re-attach the very file that was deleted — its sandbox mtime has not
	// moved. Clients filter these out; the bytes are already reclaimed.
	DeletedAt *time.Time `json:"deleted_at,omitempty"`
}

MessageArtifact represents a file produced by a skill script during a chat turn. Unlike MessageAttachment (which stores files uploaded by the user), MessageArtifact records files that the sandbox generated on the model's behalf and that WeKnora has persisted to its file service so the user can download them after the sandbox is reaped.

SourcePath + ModTime is the cheap identity for an unchanged sandbox file. When mtime moves, ArtifactCollector compares content hashes so a git checkout cannot duplicate a blob and a same-size rewrite still attaches.

func (MessageArtifact) Deleted 

func (a MessageArtifact) Deleted() bool

Deleted reports whether the user deleted this artifact.

type MessageArtifactRecord 

type MessageArtifactRecord struct {
	ID          string `gorm:"type:varchar(36);primaryKey"`
	SessionID   string `gorm:"column:session_id"`
	MessageID   string `gorm:"column:message_id"`
	Position    int    `gorm:"column:position"`

	FileName    string `gorm:"column:file_name"`
	FileType    string `gorm:"column:file_type"`
	FileSize    int64  `gorm:"column:file_size"`
	ContentHash string `gorm:"column:content_hash"`
	SourcePath  string `gorm:"column:source_path"`
	// ModTime is RFC 3339 text rather than a timestamp column: the collector
	// matches files on (source path, mtime) at nanosecond precision, which
	// PostgreSQL timestamps would truncate to microseconds. Empty means zero.
	ModTime   string    `gorm:"column:mod_time"`
	CreatedAt time.Time `gorm:"column:created_at"`
	// DeletedAt is set when the user deleted the file. The row is a tombstone
	// from then on: it holds position (the download address) and keeps the
	// collector from re-attaching the sandbox file, while the blob itself has
	// been reclaimed. URL is left in place so a later GC can retry a reclaim
	// that failed.
	DeletedAt *time.Time `gorm:"column:deleted_at"`
}

MessageArtifactRecord is one row of message_artifacts: a MessageArtifact plus the message it belongs to and its position in that message's list. Position is the index the download endpoint addresses the file by.

func NewMessageArtifactRecords 

func NewMessageArtifactRecords(sessionID, messageID string, list MessageArtifacts) []MessageArtifactRecord

NewMessageArtifactRecords turns a message's artifact list into table rows.

CreatedAt is stored in UTC: SQLite compares DATETIME values as text, so mixing zones would break ORDER BY created_at. A zero CreatedAt (an artifact built outside the collector) falls back to now, matching what the collector would have stamped.

func (MessageArtifactRecord) Artifact 

func (r MessageArtifactRecord) Artifact() MessageArtifact

Artifact converts the row back to the value carried on Message.Artifacts.

func (MessageArtifactRecord) TableName 

func (MessageArtifactRecord) TableName() string

TableName implements gorm's tabler.

type MessageArtifacts 

type MessageArtifacts []MessageArtifact

MessageArtifacts is a slice of MessageArtifact for database storage.

func (MessageArtifacts) Live 

func (m MessageArtifacts) Live() MessageArtifacts

Live returns the artifacts the user has not deleted, preserving order. The caller loses the positional index, so use it for counting and display only — anything that addresses an artifact for download must index the full slice.

func (*MessageArtifacts) Scan 

func (m *MessageArtifacts) Scan(value interface{}) error

Scan implements the sql.Scanner interface for database deserialization

func (MessageArtifacts) Value 

func (m MessageArtifacts) Value() (driver.Value, error)

Value implements the driver.Valuer interface for database serialization

func (MessageArtifacts) WithRestoredMtime 

func (m MessageArtifacts) WithRestoredMtime(sourcePath string, mod time.Time, hash string) (MessageArtifacts, bool)

WithRestoredMtime stamps sandbox mtime onto the artifact at sourcePath whose ContentHash already matches. Used after a fork checkout so later collects can skip by path+mtime. Other versions at the same path — including empty-hash legacy rows — are left alone. The returned slice is a copy.

type MessageAttachment 

type MessageAttachment struct {
	ID string `json:"id,omitempty"` // Temporary document ID for session-scoped uploads
	// URL is the internal storage handle (provider://path / resource://...). It is
	// an internal locator only: previews are served via the session-scoped

	Status     string `json:"-"`
	Outline    string `json:"-"`
	ImageCount int    `json:"-"`
}

MessageAttachment represents a file attachment in a chat message

type MessageAttachments 

type MessageAttachments []MessageAttachment

MessageAttachments is a slice of MessageAttachment for database storage

func (MessageAttachments) BuildAgentPrompt 

func (attachments MessageAttachments) BuildAgentPrompt() string

BuildAgentPrompt renders attachments for an agent turn. Uploads without a stored document keep their extracted content (see BuildPrompt); stored documents are listed as a manifest the agent reads on demand through read_file, with only small, fully parsed files inlined.

func (MessageAttachments) BuildPrompt 

func (attachments MessageAttachments) BuildPrompt() string

BuildPrompt returns a formatted prompt section for all attachments, injecting file metadata and extracted content into the LLM context.

func (*MessageAttachments) Scan 

func (m *MessageAttachments) Scan(value interface{}) error

Scan implements the sql.Scanner interface for database deserialization

func (MessageAttachments) Value 

func (m MessageAttachments) Value() (driver.Value, error)

func PickChatModel added in v0.9.0 

func PickChatModel(models []*Model, preferredID string) *Model

PickChatModel returns the active KnowledgeQA model to use for a background task: preferredID when it is usable, else the default, else the first active one. Nil means the workspace has no active chat model.

func PickDefaultModel added in v0.9.0 

func PickDefaultModel(models []*Model, modelType ModelType) *Model

PickDefaultModel prefers a workspace purpose default, then a deployment default of the native type, then the first usable model.

func PickUtilityModel added in v0.9.0 

func PickUtilityModel(models []*Model) *Model

PickUtilityModel resolves background defaults from ListModels, including workers whose context carries only a tenant ID. An explicit task model is handled by the caller before falling back here.

func (*Model) BeforeCreate 

func (m *Model) BeforeCreate(tx *gorm.DB) (err error)

BeforeCreate is a GORM hook that runs before creating a new model record. Generates a UUID only when the caller has not supplied an ID — preserves stable IDs declared in built-in model YAML config while keeping the existing UUID behaviour for API-driven model creation.

	// facts the agent cannot discover but has to act on: the context window is
	// what decides when conversation history gets compacted, and assuming a

OrganizationMemberResponse represents a member in API responses.

Post-Plan-3: every row is a (org, tenant) tuple. TenantID + TenantName are the primary identity; UserID / Username / Email / Avatar describe the representative user (informational, may be empty if the rep user was soft-deleted). RepresentativeUserID is the same value as UserID, kept as an explicit alias so frontends can stop relying on the misleading user_id field name.

type OrganizationResponse 

type OrganizationResponse struct {
	ID          string `json:"id"`
	Name        string `json:"name"`
	Description string `json:"description"`

OrganizationResponse represents an organization in API responses

type OrganizationSharedAgentItem 

type OrganizationSharedAgentItem struct {
	SharedAgentInfo
	IsMine bool `json:"is_mine"`
}

type OrganizationSharedKnowledgeBaseItem 

type OrganizationSharedKnowledgeBaseItem struct {
	SharedKnowledgeBaseInfo
	IsMine          bool                 `json:"is_mine"`
	SourceFromAgent *SourceFromAgentInfo `json:"source_from_agent,omitempty"`
}

OrganizationSharedKnowledgeBaseItem is used by GET /organizations/:id/shared-knowledge-bases (space-scoped list including mine). When SourceFromAgent is set, the KB is from a shared agent's config (no direct KB share); show as read-only and "来自智能体 XXX".

type OrganizationTenantMember 

type OrganizationTenantMember struct {
	ID                   string        `json:"id" gorm:"type:varchar(36);primaryKey"`
	OrganizationID       string        `json:"organization_id" gorm:"type:varchar(36);not null;index"`

	Organization       *Organization `json:"organization,omitempty" gorm:"foreignKey:OrganizationID"`
	RepresentativeUser *User         `json:"representative_user,omitempty" gorm:"foreignKey:RepresentativeUserID"`
}

OrganizationTenantMember represents a tenant participating in an organization. Plan 3 of #1303 lifts the "Org member" abstraction from per-user (`organization_members`) to per-tenant (this table). The representative_user_id is informational only — the user who first brought this tenant into the org — and is used purely for UI/audit labels. Permission checks are driven exclusively by (org, tenant, role).

func (OrganizationTenantMember) TableName 

func (OrganizationTenantMember) TableName() string

TableName returns the table name for GORM

	// ReturnPath is the in-app path a navigate left, for going back.
	ReturnPath string `json:"return_path,omitempty"`
}

PageActionPromptResponse is the Response of an AgentPromptKindPageAction. Declined means the browser would not act, e.g. the user turned page access off; Error means it tried and nothing was changed.

type PageContext added in v0.9.0 

type PageContext struct {
	Page            string   `json:"page,omitempty"`
	Section         string   `json:"section,omitempty"` // part of the page in view, e.g. an editor tab

	// View is the title of the dialog or drawer open over the page, as the
	// page shows it. Assistant only.
	View string `json:"view,omitempty"`
	// Selection is the text the user selected on the page. Assistant only.
	Selection *PageSelection `json:"selection,omitempty"`
}

PageContext identifies the open page. Knowledge-base resources must be in the resolved search targets; agents are checked independently in the current tenant. Models, MCP services and chat messages are resolved for the assistant only: the first two in the current tenant, messages through the caller's session read access.

type PageFillApplied added in v0.9.0 

type PageFillApplied struct {
	Ref     string `json:"ref"`
	Label   string `json:"label,omitempty"`

	Field     string `json:"field,omitempty"`      // the field's label
	Ref       string `json:"ref,omitempty"`        // the field's read_page ref
	StartLine int    `json:"start_line,omitempty"` // 1-based, multi-line fields only
	EndLine   int    `json:"end_line,omitempty"`
}

PageSelection is text the user selected on the page: in a text field (Field, Ref and the lines are set) or in the page's text.

func (*PageSelection) Normalize added in v0.9.0 

func (s *PageSelection) Normalize() *PageSelection

Normalize trims and bounds a client-sent selection; nil when nothing is left.

type PageTextEdit added in v0.9.0 

type PageTextEdit struct {
	Op string `json:"op"`
	// OldText is the text a replace swaps out; it must occur exactly once.
	OldText string `json:"old_text,omitempty"`
	// Anchor is the text an insert goes before or after; it must occur
	// exactly once.
	Anchor string `json:"anchor,omitempty"`
	Text   string `json:"text"`
}

PageTextEdit is one change to a text field, located by text rather than position so it still lands after the user typed elsewhere.

type Pagination 

type Pagination struct {
	// Page
	Page int `form:"page"      json:"page"      binding:"omitempty,min=1"`
	// Page size

type ParsedChunk 

type ParsedChunk struct {
	Content string
	// ContextHeader is an optional context string (e.g. a Markdown heading
	// breadcrumb) that should be prepended at embedding time but is NOT
	// part of the stored Content. Lets retrieval pipelines see section
	// context without breaking End-Start == len(Content) invariants.
	ContextHeader string
	Seq           int
	Start         int
	End           int
	Images        []ParsedImage
	ChunkID       string // populated by processChunks with the actual DB UUID

	// ParentIndex is set when using parent-child chunking strategy.
	// -1 (or unset/0 for flat chunks) means this is a top-level chunk.
	// >= 0 means this is a child chunk referencing the parent at this index
	// in the ParentChunks slice of ProcessChunksOptions.
	ParentIndex int

	// SourceLocators point back into the original file.
	SourceLocators SourceLocators
}

func (ParsedChunk) EmbeddingContent 

func (c ParsedChunk) EmbeddingContent() string

EmbeddingContent returns the text that should be sent to the embedding model: ContextHeader (if any) prepended to Content. Mirrors chunker.Chunk.EmbeddingContent so the choice is consistent across the chunker output and the indexing pipeline. Surrounding whitespace on Content is trimmed so leading/trailing newlines from boundary slicing don't dilute the embedded vector.

type ParsedImage 

type ParsedImage struct {
	URL         string
	Caption     string
	OCRText     string
	OriginalURL string
	Start       int

ParsedParentChunk represents a parent chunk in the parent-child strategy. Parent chunks are stored in DB for context retrieval but NOT vector-indexed.

type ParserEngineConfig 

type ParserEngineConfig struct {
	// ChatParserEngineRules selects parser engines for session-scoped chat
	// documents. Knowledge bases keep their own rules in ChunkingConfig.
	ChatParserEngineRules []ParserEngineRule `json:"chat_parser_engine_rules,omitempty"`
	MinerUEndpoint        string             `json:"mineru_endpoint"` // MinerU 自建服务端点

	Attachments         MessageAttachments // File attachments (processed and ready for prompt injection)
	QuestionOrigin      *QuestionOrigin    // Source of a picked suggested question; a retrieval hint only
	PageContext         *PageContext       // Page the user has open; a hint inside the resolved scope only
	// AssistantAccess is the access level the user picked for the WeKnora
	// assistant; the workspace ceiling still caps it. Ignored by other agents.
	AssistantAccess AssistantAccessLevel
	// SteerSink, when set, enables mid-run message injection for this run:
	// the engine drains user-appended messages at every round boundary and
	// persists accepted ones through this sink. A structural interface so
	// neither package imports the other; handler-owned, nil for IM/embed.
	SteerSink SteerSink
	// TurnLeaseHeld reports that the caller already took the session's
	// send-side turn lease (and already rejected the send if a rewind holds
	// the session) before persisting this turn's messages. HTTP send does;
	// IM/MCP, which call the QA services directly, do not and leave this
	// false so the service takes the lease itself.
	TurnLeaseHeld bool
	// Suspendable lets the run end while it waits on a user prompt and be
	// resumed later. Set by callers whose client can render a suspended
	// message and answer it afterwards (web, embed, API); IM and MCP callers
	// wait synchronously.
	Suspendable bool
	// Mode says whether anyone can answer a prompt the agent raises, such as
	// an ask_user question or a tool approval. Empty is unattended: API-key,
	// IM and MCP-server callers cannot answer prompts.
	Mode RunMode
	// GrantSessionID is the session whose "allow for this session" grants
	// the run uses: the root conversation for a delegated child, empty for
	// the run's own session.
	GrantSessionID string
	// Resume, when set, continues a suspended run instead of starting one.
	Resume *AgentResume
	// RunNote is appended to the system prompt of this run only: how the
	// run was started, for runs nobody is watching.

	IntentClarification QueryIntent = "clarification"
)

func NormalizeQueryIntent 

func NormalizeQueryIntent(raw string) QueryIntent

NormalizeQueryIntent maps a model-produced intent label onto a known intent. Case and separators are forgiven ("KB-Search" → kb_search); an unknown label becomes the empty intent, which retrieves. Taking the label verbatim turned any unexpected value into "no retrieval", so the answer was generated without the knowledge base and without an error.

func (QueryIntent) NeedsKBRetrieval 

func (i QueryIntent) NeedsKBRetrieval() bool

NeedsKBRetrieval returns true when the intent requires knowledge base search. The zero value (empty string) is treated as needing retrieval for safety. Note: IntentWebSearch is NOT included — use ChatManage.NeedsRetrieval() which also considers the WebSearchEnabled flag.

	// can record a postprocess.question subspan under the right attempt's
	// postprocess stage. 0 means "skip span recording" (legacy in-flight
	// tasks queued before this field shipped, or callers without a
	// tracker).
	Attempt int `json:"attempt,omitempty"`
	// ChunkIDs switches the handler into batched fan-out mode: the task
	// generates questions for this ordered window of text chunks only.
	// Batching (rather than one task per chunk) keeps the task count
	// bounded for very large documents, while still giving each batch
	// independent retry / cancellation / tracing and letting the worker
	// do a single embedding BatchIndex per batch. Empty means the legacy
	// whole-knowledge mode (kept for in-flight tasks queued before fan-out
	// shipped), where the handler iterates all text chunks itself.
	// Following the ExtractChunkPayload precedent, we carry only chunk ids
	// (not their content) so the payload stays small and the worker reads
	// fresh content at run time.
	ChunkIDs []string `json:"chunk_ids,omitempty"`
	// ChunkID is the single-chunk variant of ChunkIDs, retained only so
	// tasks enqueued by an interim per-chunk build still run (treated as a
	// one-element batch). New enqueues use ChunkIDs.
	ChunkID string `json:"chunk_id,omitempty"`
	// BatchIndex is the 0-based ordinal of this batch inside the parent
	// knowledge's text-chunk set, used as the subspan name suffix
	// ("postprocess.question.batch[3]") so the timeline preserves order.
	BatchIndex int `json:"batch_index,omitempty"`
	// PrevChunkID / NextChunkID are the text chunks (by StartAt) just
	// outside this batch window, computed at enqueue time so the worker can
	// rebuild the same surrounding context the legacy whole-knowledge loop
	// used at the batch boundaries, without re-listing every chunk of the
	// knowledge. Empty when the batch is at a document boundary.
	PrevChunkID string `json:"prev_chunk_id,omitempty"`
	NextChunkID string `json:"next_chunk_id,omitempty"`
}

QuestionGenerationPayload represents the question generation task payload

type QuestionOrigin 

type QuestionOrigin struct {
	KnowledgeBaseID string `json:"knowledge_base_id"`
	KnowledgeID     string `json:"knowledge_id,omitempty"`
}

QuestionOrigin names the knowledge source a suggested question was generated from. The client sends it with the question the user picked so the agent searches that source before answering; it is a hint inside the turn's resolved scope, never a scope change.

type QuestionSuggestionConfig 

type QuestionSuggestionConfig struct {
	Starters  StarterSuggestionConfig  `yaml:"starters" json:"starters"`
	FollowUps FollowUpSuggestionConfig `yaml:"follow_ups" json:"follow_ups"`
}

QuestionSuggestionConfig is the agent-owned configuration for question suggestions. Channel settings may suppress rendering, but never override this content/generation policy.

func (*QuestionSuggestionConfig) EnsureDefaults 

func (c *QuestionSuggestionConfig) EnsureDefaults()

EnsureDefaults normalizes suggestion configuration without overriding explicit enable/disable choices.

func (*QuestionSuggestionConfig) Validate 

func (c *QuestionSuggestionConfig) Validate() error

Validate rejects invalid agent-authored suggestion settings before they are persisted or used to incur a model call.

type QueueDefinition 

type QueueDefinition struct {
	Name         string
	Pool         string
	Weight       int
	SharedWeight int
	TaskTypes    []string
}

QueueDefinition is the single source of truth for queue topology. Worker servers and runtime inspection both consume this registry, preventing the scheduling weights shown to operators from drifting from the actual server configuration.

func QueueDefinitions 

func QueueDefinitions() []QueueDefinition

QueueDefinitions returns a copy so callers cannot mutate global topology.

type QueueStat 

type QueueStat struct {
	Name string `json:"name" extensions:"x-agent"`
	// Pool is the independent worker pool that drains this queue.
	Pool string `json:"pool" extensions:"x-agent"`
	// Weight is the queue's scheduling weight inside its pool.
	Weight int `json:"weight" extensions:"x-agent"`
	// Size is the total number of tasks in the queue (pending + active +
	// scheduled + retry + aggregating + archived).
	Size      int `json:"size" extensions:"x-agent"`
	Pending   int `json:"pending" extensions:"x-agent"`
	Active    int `json:"active" extensions:"x-agent"`
	Scheduled int `json:"scheduled" extensions:"x-agent"`
	Retry     int `json:"retry" extensions:"x-agent"`
	Archived  int `json:"archived" extensions:"x-agent"`
	Completed int `json:"completed" extensions:"x-agent"`
	// Processed / Failed are today's counters (reset daily).
	Processed int `json:"processed" extensions:"x-agent"`
	Failed    int `json:"failed" extensions:"x-agent"`
	// Paused reports whether the queue is paused (tasks not consumed).
	Paused bool `json:"paused" extensions:"x-agent"`
	// LatencyMs is the age of the oldest pending task, in milliseconds.
	LatencyMs int64 `json:"latency_ms" extensions:"x-agent"`
	// MemoryUsageBytes is the approximate Redis memory the queue occupies.
	MemoryUsageBytes int64 `json:"memory_usage_bytes"`
}

QueueStat is a read-only depth snapshot of a single asynq queue, used by the System Admin runtime dashboard. Field names mirror the counts exposed by asynq.QueueInfo. Pool / Weight are static metadata (which worker pool drains the queue and its scheduling weight within that pool) so the UI can group and explain the lanes without the frontend hard-coding the topology.

type ReadRequest 

type ReadRequest struct {
	FileContent           []byte
	FileName              string
	FileType              string

	IsAudio         bool   // true when the result contains raw audio data needing ASR transcription
	AudioData       []byte // raw audio bytes for ASR processing
	// SourceBlocks map rune ranges of MarkdownContent back to positions in
	// the original file. Optional: engines that know no positions leave it
	// empty.
	SourceBlocks []SourceBlock
}

	ImagesKept   int `json:"images_kept,omitempty"`
	// Error carries the reason for model_error / model_unavailable.
	Error string `json:"error,omitempty"`
}

RerankDiagnostics reports what the rerank stage did, so an empty or unexpectedly ordered result can be explained to API callers.

type RerankOptions 

type RerankOptions struct {
	// Enabled turns the rerank stage off when explicitly false. Nil means on.
	Enabled *bool `json:"enabled,omitempty"`
	// ModelID selects the rerank model. Empty falls back to the tenant
	// RetrievalConfig, then to the first rerank model of the tenant.
	ModelID string `json:"model_id,omitempty"`
	// TopK caps the reranked results. Zero uses the endpoint's result count.
	TopK int `json:"top_k,omitempty"`
	// Threshold is the minimum rerank model score. Nil uses the tenant
	// RetrievalConfig. A pointer because 0 and negative scores are valid.
	Threshold *float64 `json:"threshold,omitempty"`
}

RerankOptions is the per-request rerank control shared by the retrieval APIs (knowledge-search and hybrid-search).

On hybrid-search, an absent object means "no rerank" (the endpoint is a raw recall primitive). On knowledge-search, an absent object means "rerank with the tenant configuration", which is what the endpoint has always done.

func (*RerankOptions) IsEnabled 

func (o *RerankOptions) IsEnabled() bool

IsEnabled reports whether the options ask for a rerank stage. A nil receiver is not enabled; callers decide what an absent object means.

type RetrievalMeta 

type RetrievalMeta struct {
	Rerank *RerankDiagnostics `json:"rerank,omitempty"`
}

RetrievalMeta is the diagnostic envelope returned beside retrieval API results.

type RetrievalMetrics 

type RetrievalMetrics struct {
	Precision float64 `json:"precision"` // Precision score
	Recall    float64 `json:"recall"`    // Recall score

type RetrievalTruncation 

type RetrievalTruncation struct {
	Stage      string `json:"stage"`
	Candidates int    `json:"candidates"`
}

RetrievalTruncation records that the passages in the model context are a subset of this turn's ranked candidates.

Stage is the first pipeline stage that dropped candidates and Candidates is the number of candidate passages that stage received, so the pair always describes one population: the retrieval set that entered the ranked filter chain (rerank → merge → FILTER_TOP_K). Candidates is a pipeline-local count of retrieved passages — never the number of matches in the knowledge base, which retrieval never computes — and a later, narrower cut never replaces it. How many of those candidates the prompt actually shows is counted where the prompt is built, so the caveat is only emitted when the context really is a subset.

	// including a genuine zero-hit search. A store-level failure is still
	// returned as the call's error with no result set at all.
	// CompositeRetrieveEngine surfaces a non-nil Error as an error alongside the
	// results, so a caller that reads the results must not ignore the error
	// without at least logging that the answer is incomplete.

func (RunMode) Normalize added in v0.9.0 

func (m RunMode) Normalize() RunMode

Normalize returns m, treating anything unknown, including empty, as unattended: a run is only answerable when its caller says so.

type RuntimeTaskAction 

type RuntimeTaskAction string

RuntimeTaskAction is returned by the backend for every task. The frontend renders only these actions instead of inferring safety from the state. 

const (
	RuntimeTaskActionCancel RuntimeTaskAction = "cancel"
	RuntimeTaskActionRunNow RuntimeTaskAction = "run_now"

}

RuntimeTaskInfo is the safe SystemAdmin projection of one queue task. Raw payloads and results are deliberately excluded because they may contain document content, signed object URLs, or connector credentials.

func (RuntimeTaskInfo) Allows 

func (t RuntimeTaskInfo) Allows(action RuntimeTaskAction) bool

type RuntimeTaskPage 

type RuntimeTaskPage struct {
	Tasks      []RuntimeTaskInfo
	NextCursor string
	HasMore    bool
}

RuntimeTaskPage is one stable slice of the operator task list. NextCursor is opaque to HTTP clients and remains tied to the selected queue/state.

type RuntimeTaskState 

type RuntimeTaskState string

RuntimeTaskState is the stable operator-facing task lifecycle. It mirrors the durable states exposed by asynq while keeping the HTTP API independent from the queue library's Go enum. 

const (
	RuntimeTaskPending   RuntimeTaskState = "pending"
	RuntimeTaskActive    RuntimeTaskState = "active"
	RuntimeTaskScheduled RuntimeTaskState = "scheduled"
	RuntimeTaskRetry     RuntimeTaskState = "retry"
	RuntimeTaskArchived  RuntimeTaskState = "archived"
	RuntimeTaskCompleted RuntimeTaskState = "completed"
)

func (RuntimeTaskState) Valid 

func (s RuntimeTaskState) Valid() bool

type S3EngineConfig 

type S3EngineConfig struct {
	Endpoint       string `json:"endpoint"`
	Region         string `json:"region"`
	AccessKey      string `json:"access_key"`
	SecretKey      string `json:"secret_key"`
	BucketName     string `json:"bucket_name"`
	PathPrefix     string `json:"path_prefix"`
	UseSSL         bool   `json:"use_ssl"`

S3EngineConfig is for AWS S3 and S3-compatible object storage.

type SandboxCheckpoint 

type SandboxCheckpoint struct {
	SandboxID   string    `json:"sandbox_id"`
	CommitSHA   string    `json:"commit_sha"`
	CommittedAt time.Time `json:"committed_at"`
	// BackgroundActive marks a commit taken while background work was live in
	// the session. The work may have been mid-write, so fork and rewind never
	// roll a workspace back to it.
	BackgroundActive bool `json:"background_active,omitempty"`
}

SandboxCheckpoint records the git commit an agent turn produced inside the session sandbox's /workspace. It is written on assistant messages only.

SandboxID is stored alongside CommitSHA because commit hashes are only meaningful within one sandbox's repository. When a session's sandbox is reaped and rebuilt mid-conversation the in-sandbox git history restarts from zero, so every checkpoint written before the rebuild becomes unreachable. Comparing SandboxID against the session's current binding detects that purely from the database, without probing the sandbox.

func (*SandboxCheckpoint) Scan 

func (c *SandboxCheckpoint) Scan(value any) error

Scan implements the sql.Scanner interface for database deserialization.

func (SandboxCheckpoint) Value 

func (c SandboxCheckpoint) Value() (driver.Value, error)

Value implements the driver.Valuer interface for database serialization.

type SandboxNetworkPolicy 

type SandboxNetworkPolicy struct {
	// DenyEgressByDefault installs a 0.0.0.0/0 deny-all, after which only
	// AllowOut (and L7 rule targets) can reach the network. false allows
	// public egress, which is what skill installs need.
	DenyEgressByDefault bool `json:"deny_egress_by_default,omitempty"`

	// AllowPublicInbound is accepted on the wire for old payloads and then
	// cleared. Inbound is always credential-required; a true value has no
	// runtime effect.
	AllowPublicInbound bool `json:"allow_public_inbound,omitempty"`

	// AllowOut accepts IPv4, IPv4 CIDR, a DNS name, or a single-label
	// wildcard such as "*.example.com". Domain entries are only meaningful
	// together with a deny-all; see ValidateSandboxNetworkPolicy.
	AllowOut []string `json:"allow_out,omitempty"`

	// DenyOut accepts IPv4 and IPv4 CIDR only. Neither provider can deny a
	// domain: denial is a pure longest-prefix match on the destination IP.
	DenyOut []string `json:"deny_out,omitempty"`

	// CubeRules are validated whenever present and consumed only by the Cube
	// provider adapter.
	CubeRules []CubeEgressRule `json:"cube_rules,omitempty"`

	// E2BHostRules are validated whenever present and consumed only by the E2B
	// provider adapter.
	E2BHostRules []E2BHostRule `json:"e2b_host_rules,omitempty"`
}

SandboxNetworkPolicy is the admin-facing network policy for one sandbox config. DenyEgressByDefault is phrased so the zero value IS the intended default (outbound open). Inbound is not a switch: it is always credential-required. AllowPublicInbound stays on the wire so old payloads still decode, then is cleared on save and ignored at resolve.

func (*SandboxNetworkPolicy) CloneWithSecrets 

func (p *SandboxNetworkPolicy) CloneWithSecrets(
	transform func(string) string,
) *SandboxNetworkPolicy

CloneWithSecrets deep-copies p, passing every credential-bearing field through transform. Both the encrypt (Value), decrypt (Scan) and mask (SandboxConfigForResponse) directions share it so they cannot drift about which fields count as secrets. The receiver is never mutated.

type SandboxUserMachine added in v0.9.0 

type SandboxUserMachine struct {
	MachineDigest  string     `gorm:"column:machine_digest;type:varchar(64);primaryKey"`
	OwnerTenantID  uint64     `gorm:"column:owner_tenant_id;not null"`
	OwnerID        string     `gorm:"column:owner_id;type:varchar(512);not null"`
	ConfigTenantID uint64     `gorm:"column:config_tenant_id;not null"`
	ConfigID       string     `gorm:"column:config_id;type:varchar(64);not null"`
	EmptySince     *time.Time `gorm:"column:empty_since"`
}

SandboxUserMachine is the logical registry row of one shared machine: the identity behind its digest, and the empty-retention clock.

func (SandboxUserMachine) TableName added in v0.9.0 

func (SandboxUserMachine) TableName() string

TableName is the shared-machine registry table.

Session represents the session

func (*Session) BeforeCreate 

func (s *Session) BeforeCreate(tx *gorm.DB) (err error)

func (*Session) SandboxConfigOwner 

func (s *Session) SandboxConfigOwner() uint64

SandboxConfigOwner returns the workspace SandboxConfigID must be looked up in. Sandbox configs are keyed by (tenant, id), so the two always travel together; a shared agent's sandbox lives on the LENDING workspace's config while the session belongs to the borrower. Zero falls back to the session's own tenant, which is right for every sandbox an own agent created and for pins written before the owner was recorded.

type SessionAgentConfig 

type SessionAgentConfig struct {
	AgentModeEnabled bool     `json:"agent_mode_enabled"` // Whether agent mode is enabled for this session
	WebSearchEnabled bool     `json:"web_search_enabled"` // Whether web search is enabled for this session
	KnowledgeBases   []string `json:"knowledge_bases"`    // Accessible knowledge base IDs for this session
	KnowledgeIDs     []string `json:"knowledge_ids"`      // Accessible knowledge IDs (individual documents) for this session
}

SessionAgentConfig represents session-level agent configuration Sessions only store Enabled and KnowledgeBases; other configs are read from Tenant at runtime

func (*SessionAgentConfig) Scan 

func (c *SessionAgentConfig) Scan(value interface{}) error

Scan implements sql.Scanner interface for SessionAgentConfig

func (SessionAgentConfig) Value 

func (c SessionAgentConfig) Value() (driver.Value, error)

Value implements driver.Valuer interface for SessionAgentConfig

type SessionLastRequestState 

type SessionLastRequestState struct {
	AgentID             string         `json:"agent_id,omitempty"`
	AgentEnabled        bool           `json:"agent_enabled"`

	LocalBrowserEnabled bool           `json:"local_browser_enabled"`
	WebSearchEnabled    bool           `json:"web_search_enabled"`
}

SessionLastRequestState captures the user-facing input-bar state at the time of the most recent QA request on a session. It is purely a UI memory aid — none of the fields here drive backend behaviour. They are echoed back to the frontend by GetSession so the chat input can restore the same agent, model, KB scope, etc. the user had selected last time.

func (*SessionLastRequestState) Scan 

func (s *SessionLastRequestState) Scan(value interface{}) error

Scan implements sql.Scanner for SessionLastRequestState (JSONB). Tolerates legacy values that may not match the current schema by silently ignoring unmarshal errors — the stored row predates this struct.

func (*SessionLastRequestState) Value 

func (s *SessionLastRequestState) Value() (driver.Value, error)

Value implements driver.Valuer for SessionLastRequestState (JSONB).

type SessionListItem 

type SessionListItem struct {
	Session
	IMPlatform  string `json:"im_platform,omitempty"   gorm:"column:im_platform"`
	IMChatID    string `json:"im_chat_id,omitempty"    gorm:"column:im_chat_id"`
	IMThreadID  string `json:"im_thread_id,omitempty"  gorm:"column:im_thread_id"`
	IMUserID    string `json:"im_user_id,omitempty"    gorm:"column:im_user_id"`
	IMAgentID   string `json:"im_agent_id,omitempty"   gorm:"column:im_agent_id"`
	IMChannelID string `json:"im_channel_id,omitempty" gorm:"column:im_channel_id"`
}

SessionListItem is a session row enriched with its IM origin (when any). IM-related fields are populated from the im_channel_sessions table via LEFT JOIN and are empty for Web-created sessions.

type SessionListQuery 

type SessionListQuery struct {
	Kind     string
	TenantID uint64
	UserID   string
	Keyword  string
	Source   string
	AgentID  string
	Page     int
	PageSize int
}

SessionListQuery bundles the parameters for listing sessions. UserID empty means "tenant-wide" (used by API-key callers / legacy rows). Keyword matches title ILIKE '%keyword%'. Source values: "web" (user chats, no IM/embed), "embed" / "embed:{channelID}", "api" (all API-key sessions, Admin+ only), or an IM platform name (e.g. "feishu", "wechat"). IM and embed sources are also Admin+ only. AgentID currently only filters sessions that have an IM channel mapping.

type SessionSandboxAssignment added in v0.9.0 

type SessionSandboxAssignment struct {
	SessionID      string `gorm:"column:session_id;type:varchar(36);primaryKey"`
	ConfigTenantID uint64 `gorm:"column:config_tenant_id;not null;default:0"`
	ConfigID       string `gorm:"column:config_id;type:varchar(64);not null;default:''"`
	MachineDigest  string `gorm:"column:machine_digest;type:varchar(64);not null;default:''"`
	// ReleasedAt marks a deleted (retired) session. A row that has it may
	// never be placed again; a session retired before its first placement
	// gets such a row with an empty ConfigID (a tombstone).
	ReleasedAt *time.Time `gorm:"column:released_at"`
	// CleanupDueAt is set while the session's directory on a shared machine
	// still has to be removed, and is the time of the next attempt.
	CleanupDueAt *time.Time `gorm:"column:cleanup_due_at"`
}

SessionSandboxAssignment is the persisted placement of one session on remote sandboxes. Written once on first use by sandboxalloc; never rewritten except to release the session.

Everything else about the placement is derived: the mode and workspace layout from MachineDigest (empty = a machine of the session's own), the owner of a shared machine from its sandbox_user_machines row, and the owner's eligibility from the session row.

func (*SessionSandboxAssignment) IsTombstone added in v0.9.0 

func (a *SessionSandboxAssignment) IsTombstone() bool

IsTombstone reports a row written only to retire a session that was never placed. Real placements always carry a normalized, non-empty config id.

func (SessionSandboxAssignment) TableName added in v0.9.0 

func (SessionSandboxAssignment) TableName() string

TableName is the assignments table.

type ShareKnowledgeBaseRequest 

type ShareKnowledgeBaseRequest struct {
	OrganizationID string        `json:"organization_id" binding:"required"`
	Permission     OrgMemberRole `json:"permission" binding:"required"`
}

ShareKnowledgeBaseRequest represents a request to share a knowledge base

type SharedAgentInfo 

type SharedAgentInfo struct {
	Agent            *CustomAgent  `json:"agent"`
	ShareID          string        `json:"share_id"`
	OrganizationID   string        `json:"organization_id"`
	OrgName          string        `json:"org_name"`
	Permission       OrgMemberRole `json:"permission"`
	SourceTenantID   uint64        `json:"source_tenant_id"`
	SharedAt         time.Time     `json:"shared_at"`
	SharedByUserID   string        `json:"shared_by_user_id,omitempty"`
	SharedByUsername string        `json:"shared_by_username,omitempty"`
	// WebSearchReady is resolved against the source workspace without exposing
	// its provider list or credentials. Receivers must not compare the agent's
	// provider ID with their own workspace resources.
	WebSearchReady bool `json:"web_search_ready"`
	// DisabledByMe: current tenant has hidden this shared agent from their conversation dropdown (per-user preference)
	DisabledByMe bool `json:"disabled_by_me"`
}

SharedAgentInfo represents a shared agent with additional sharing info

type SharedAgentKBScope 

type SharedAgentKBScope struct {
	// contains filtered or unexported fields
}

SharedAgentKBScope describes the KBs exposed by an already-authorized shared agent. It is not proof that a caller can use that agent. The zero value, an unknown selection mode, and an empty selection all deny access.

func NewSharedAgentKBScope 

func NewSharedAgentKBScope(agent *CustomAgent) SharedAgentKBScope

NewSharedAgentKBScope snapshots an authorized agent configuration.

func (SharedAgentKBScope) Allows 

func (s SharedAgentKBScope) Allows(kbID string, tenantID uint64) bool

Allows checks both the KB selection and the authoritative owner tenant.

func (SharedAgentKBScope) IDs 

func (s SharedAgentKBScope) IDs() []string

IDs returns a copy of the explicit selection. Use IsAll to distinguish a whole-tenant scope from an empty selection; nil never means unrestricted.

func (SharedAgentKBScope) IsAll 

func (s SharedAgentKBScope) IsAll() bool

IsAll reports whether every KB in the source tenant is selected.

func (SharedAgentKBScope) IsEmpty 

func (s SharedAgentKBScope) IsEmpty() bool

IsEmpty reports whether the scope authorizes no KBs.

type SharedKnowledgeBaseInfo 

type SharedKnowledgeBaseInfo struct {
	KnowledgeBase  *KnowledgeBase `json:"knowledge_base"`
	ShareID        string         `json:"share_id"`
	OrganizationID string         `json:"organization_id"`
	OrgName        string         `json:"org_name"`
	Permission     OrgMemberRole  `json:"permission"`
	SourceTenantID uint64         `json:"source_tenant_id"`
	SharedAt       time.Time      `json:"shared_at"`
}

SharedKnowledgeBaseInfo represents a shared knowledge base with additional sharing info

type SkillEnvVar 

type SkillEnvVar struct {
	Name        string `json:"name"`
	Description string `json:"description,omitempty"`
	Required    bool   `json:"required,omitempty"`
	// Value is the workspace-wide admin value. It is AES-GCM encrypted at rest
	// by SkillEnvVars.Value and decrypted by SkillEnvVars.Scan. json:"-" makes
	// it unserialisable by construction: the column round-trip goes through
	// skillEnvVarRow, so no response body can carry it by forgetting to strip
	// it in a DTO.
	Value string `json:"-"`
}

SkillEnvVar is one environment variable a skill needs, as declared by the installer agent, optionally carrying the workspace-wide value an admin supplied. Everything except Value stays plaintext in the column so the UI can render the declaration even when SYSTEM_AES_KEY is unavailable.

type SkillEnvVars 

type SkillEnvVars []SkillEnvVar

SkillEnvVars is the whole declaration list, stored as one JSON column. It follows TenantSandboxConfig's driver.Valuer/sql.Scanner pattern rather than GORM hooks because the encrypted field lives inside a JSON document.

func (SkillEnvVars) Get 

func (v SkillEnvVars) Get(name string) (SkillEnvVar, bool)

Get returns the declaration for name, if the skill declares it.

func (*SkillEnvVars) Scan 

func (v *SkillEnvVars) Scan(value interface{}) error

Scan implements sql.Scanner. A value that cannot be decrypted (missing or rotated SYSTEM_AES_KEY) is reported as unset rather than failing the load, matching TenantSandboxConfig.Scan: the skill must stay listable and editable even when its stored credential became unreadable.

func (SkillEnvVars) Value 

func (v SkillEnvVars) Value() (driver.Value, error)

Value implements driver.Valuer. The receiver is never mutated: the caller holds plaintext, so encryption happens on a copy of the slice.

type SkillImageConfig 

type SkillImageConfig struct {
	// SnapshotID is the currently effective snapshot; empty = base template.
	SnapshotID string `json:"snapshot_id,omitempty"`
	// Generation increments on every successful install/remove, for naming
	// and troubleshooting.
	Generation int `json:"generation,omitempty"`
	// BuiltAt records when this generation was produced.
	BuiltAt time.Time `json:"built_at,omitempty"`
	// BaseTemplateID is the template this chain was originally built from;
	// the rebuild path starts over from it.
	BaseTemplateID string `json:"base_template_id,omitempty"`
	// OwnerFingerprint identifies the provider account that owns the snapshot.
	// Snapshots are invisible across accounts, so a mismatch means "fall back
	// to the base template" rather than "fail".
	OwnerFingerprint string `json:"owner_fingerprint,omitempty"`
}

SkillImageConfig is the pointer to the snapshot that carries the skills installed on this sandbox config. Snapshot IDs double as template IDs, so nothing else is needed to boot sessions from it.

It holds no secrets, so it is not encrypted by TenantSandboxConfig.Value.

type SkillServedVersion 

type SkillServedVersion struct {
	Version      string `json:"version,omitempty"`
	Description  string `json:"description,omitempty"`
	Instructions string `json:"instructions,omitempty"`
	BundleSHA256 string `json:"bundle_sha256,omitempty"`
	// BundleRef names the archive the served files came from. It is resolved
	// when the version is recorded, including for a row that was following the
	// catalog, because the catalog may be re-registered while the upgrade
	// runs and the served files must stay readable after it is.
	BundleRef string `json:"bundle_ref,omitempty"`
	// SnapshotID is the image generation that put this version in. The reaper
	// compares it with the live chain to tell an upgrade that never moved the
	// pointer from one whose terminal write was lost.
	SnapshotID string `json:"snapshot_id,omitempty"`
}

SkillServedVersion is what a row described when it was last ready, kept while a newer install of the same skill has not replaced it in the image.

func (*SkillServedVersion) Scan 

func (v *SkillServedVersion) Scan(value interface{}) error

Scan reads the served version back.

func (SkillServedVersion) Value 

func (v SkillServedVersion) Value() (driver.Value, error)

Value stores the served version as one JSON column.

type SourceBlock 

type SourceBlock struct {
	Start   int
	End     int
	Locator SourceLocator
}

SourceBlock ties a rune range of a parser's Markdown output to the place in the original file it came from.

type SourceFromAgentInfo 

type SourceFromAgentInfo struct {
	AgentID         string `json:"agent_id"`
	AgentName       string `json:"agent_name"`
	KBSelectionMode string `json:"kb_selection_mode"` // "all" | "selected" | "none"; for drawer copy "该智能体对知识库的策略"
}

SourceFromAgentInfo indicates the KB is visible in the space via a shared agent (read-only, no KB share record).

type SourceLocator 

type SourceLocator struct {
	Type string `json:"type"`
	// Mapping records verified text-to-source alignment. Empty means legacy.
	Mapping string `json:"mapping,omitempty"`
	// Partial means some of the chunk has no source mapping.
	Partial bool `json:"partial,omitempty"`
	// SourceID identifies a block within the parser result, not a rendered item.
	SourceID string `json:"source_id,omitempty"`
	// SourceHash binds the locator to the knowledge record’s source revision hash.
	SourceHash string `json:"source_hash,omitempty"`
	// Page is the 1-based PDF page.
	Page int `json:"page,omitempty"`
	// BBox is [x0, y0, x1, y1] as fractions of the page width and height,
	// origin at the top-left corner of the rendered page.
	BBox []float64 `json:"bbox,omitempty"`
	// Block is the 1-based index among a Word file's body paragraphs and tables.
	Block int `json:"block,omitempty"`
	// Slide is the 1-based slide number in presentation order.
	Slide int `json:"slide,omitempty"`
	// Sheet is the spreadsheet sheet name; RowStart/RowEnd are its 1-based
	// row numbers as shown by spreadsheet applications.
	Sheet    string `json:"sheet,omitempty"`
	RowStart int    `json:"row_start,omitempty"`
	RowEnd   int    `json:"row_end,omitempty"`
	// Start/End are rune offsets into the original text file.
	Start int `json:"start,omitempty"`
	End   int `json:"end,omitempty"`
	// StartMs/EndMs bound an audio segment.
	StartMs int64 `json:"start_ms,omitempty"`
	EndMs   int64 `json:"end_ms,omitempty"`
	// Section is the 1-based EPUB spine index.
	Section int `json:"section,omitempty"`
	// Title names the section or slide when the source has one.
	Title string `json:"title,omitempty"`
	// Quote is the complete cited overlap as parsed. Viewers match it
	// inside the rendered original and against the
	// answer sentence that cites the chunk.
	Quote string `json:"quote,omitempty"`
}

SourceLocator is one position in an original file. Only the fields of its Type are set; zero values are omitted from JSON and read back as zero.

type SourceLocators 

type SourceLocators []SourceLocator

SourceLocators is the per-chunk locator list, stored as a JSON column.

func (*SourceLocators) Scan 

func (s *SourceLocators) Scan(value interface{}) error

Scan implements sql.Scanner.

func (SourceLocators) Value 

func (s SourceLocators) Value() (driver.Value, error)

Value implements driver.Valuer. An empty list is stored as NULL.

type SourceType 

type SourceType int

SourceType represents the type of content source 

const (
	ChunkSourceType   SourceType = iota // Source is a text chunk
	PassageSourceType                   // Source is a passage
	SummarySourceType                   // Source is a summary
	// ImageSourceType is an image embedded by a multimodal embedding model.
	// Its vector lives in the text space but scores lower against a text
	// query than text does, and its Content is not what was embedded, so
	// retrieval gives it its own threshold and never counts it as a
	// keyword hit.
	ImageSourceType
)

type SpanTreeNode 

type SpanTreeNode struct {
	KnowledgeProcessingSpan
	Children []*SpanTreeNode `json:"children,omitempty"`
}

SpanTreeNode is the API-only tree projection. The repo returns flat rows; the handler/tracker assembles SpanTreeNode for the response.

type StarterSuggestionConfig 

type StarterSuggestionConfig struct {
	Enabled bool     `yaml:"enabled" json:"enabled"`
	Mode    string   `yaml:"mode" json:"mode"`
	Items   []string `yaml:"items" json:"items"`
	Count   int      `yaml:"count" json:"count"`
}

StarterSuggestionConfig controls prompts shown before the first user turn.

type SteerSink 

type SteerSink interface {
	// PollSteer returns pending inject events as {id, content, mentioned_items,
	// channel} maps. lastOffset is unused: consumed flags (not a numeric
	// offset) are what skip already-handled events, so an after→inject
	// promote of a previously skipped item stays visible. An empty/absent
	// queue is an empty result. PersistSteerMessage is what marks an event
	// consumed, after the user row exists.
	PollSteer(ctx context.Context, sessionID, messageID string, lastOffset int) ([]map[string]interface{}, int, error)
	// PersistSteerMessage stores the accepted message as a user-role row
	// under the run's request ID and returns the new row's ID. An empty ID
	// means persistence failed: the caller must not append the text, so the
	// next drain can retry. Mentions are recorded for history only — the
	// running turn's scope is not widened mid-flight.
	// channel is the source of the steered send ("web", "api", "im"); empty
	// is stored as "web".
	PersistSteerMessage(
		ctx context.Context, sessionID, messageID, steerID, content string,
		mentionedItems MentionedItems,
		channel string,
	) string
}

SteerSink abstracts the handler-side back half of mid-run message injection: draining the queued steer events and persisting accepted messages. Declared in types (not agent/interfaces) because both packages need the shape and neither may import the other; the engine accepts any value implementing it.

type StorageBackend 

type StorageBackend struct {
	ID          string               `json:"id" gorm:"type:varchar(36);primaryKey"`
	TenantID    uint64               `json:"tenant_id" gorm:"not null;index"`

StorageBackend is one concrete file/object storage instance. A workspace may register multiple instances of the same provider and bind each knowledge base to a different instance.

func NewStorageBackendResponse 

func NewStorageBackendResponse(backend *StorageBackend) StorageBackend

func StorageBackendFromEnvironment 

func StorageBackendFromEnvironment(tenantID uint64) *StorageBackend

StorageBackendFromEnvironment snapshots the process-wide storage backend for a workspace. The row is read-only in the UI and keeps env-only deployments on the same instance-resolution path as user-managed backends.

func StorageBackendFromLegacy 

func StorageBackendFromLegacy(tenantID uint64, provider string, legacy *StorageEngineConfig) *StorageBackend

StorageBackendFromLegacy projects one provider entry from the old workspace singleton JSON into the multi-instance model.

Deprecated: StorageConfig is the legacy COS configuration stored in the cos_config column. New code should use StorageProviderConfig. Kept for backward compatibility with old data.

func (*StorageConfig) Scan 

func (c *StorageConfig) Scan(value interface{}) error

func (StorageConfig) Value 

func (c StorageConfig) Value() (driver.Value, error)

type StorageEngineConfig 

type StorageEngineConfig struct {
	DefaultProvider string             `json:"default_provider"` // "local", "minio", "cos", "tos", "s3", "oss", "ks3", "obs"
	Local           *LocalEngineConfig `json:"local,omitempty"`

type StoreDisplay 

type StoreDisplay struct {
	Name       string `json:"vector_store_name,omitempty"`
	Source     string `json:"vector_store_source,omitempty"`
	EngineType string `json:"vector_store_engine_type,omitempty"`
	Status     string `json:"vector_store_status,omitempty"` // "available" / "unavailable"
}

StoreDisplay is the API-safe projection of a VectorStore for embedding in other resource responses (notably KnowledgeBase). It carries only the display-safe identifiers — never connection credentials.

Source is one of the StoreSource* constants. EngineType is the underlying engine name (e.g. "elasticsearch"). Status mirrors Source by default but is split out to give the UI a stable boolean-like signal independent of future Source value additions.

func DefaultStoreDisplay 

func DefaultStoreDisplay() StoreDisplay

DefaultStoreDisplay is the display payload for KBs that fall back to the tenant's env stores (VectorStoreID == nil).

func SharedStoreDisplay 

func SharedStoreDisplay() StoreDisplay

SharedStoreDisplay is returned for cross-tenant shared KB views so that the underlying owner-tenant store's name and engine remain hidden — only the fact that "this KB is shared" leaks, which is already implied by the share grant itself.

func UnavailableStoreDisplay 

func UnavailableStoreDisplay() StoreDisplay

UnavailableStoreDisplay is used when the bound store cannot be resolved (deleted row, registry miss, transient infra error). The UI can branch on Status to guide recovery (admin tool, rebind, etc.).

type StoredResource 

type StoredResource struct {
	ID               string         `json:"id" gorm:"type:varchar(36);primaryKey"`
	Handle           string         `json:"handle" gorm:"type:varchar(22);not null;uniqueIndex"`

	MimeType         string         `json:"mime_type,omitempty" gorm:"type:varchar(255);not null;default:''"`
	OriginalName     string         `json:"original_name,omitempty" gorm:"type:varchar(1024);not null;default:''"`
	Size             int64          `json:"size" gorm:"not null;default:0"`
	ContentHash      string         `json:"content_hash,omitempty" gorm:"type:varchar(64);not null;default:''"`
	Lifecycle        string         `json:"lifecycle" gorm:"type:varchar(16);not null;default:'persistent'"`
	ExpiresAt        *time.Time     `json:"expires_at,omitempty"`
	State            string         `json:"state" gorm:"type:varchar(16);not null;default:'active'"`
	CreatedAt        time.Time      `json:"created_at"`
	UpdatedAt        time.Time      `json:"updated_at"`
	DeletedAt        gorm.DeletedAt `json:"deleted_at" gorm:"index"`
}

StoredResource is the stable application identity of one stored object. PhysicalPath is deliberately internal: API responses, persisted rich text and LLM prompts use resource://<handle> instead.

func (*StoredResource) BeforeCreate 

func (r *StoredResource) BeforeCreate(_ *gorm.DB) error

BeforeCreate fills resource defaults before persistence.

func (StoredResource) TableName 

func (StoredResource) TableName() string

	Refresh bool `json:"refresh,omitempty"`
	// Attempt links this task to the parent parse attempt so the worker
	// can record a postprocess.summary subspan under the right attempt's
	// postprocess stage. See QuestionGenerationPayload.Attempt notes.
	Attempt int `json:"attempt,omitempty"`
}

SummaryGenerationPayload represents the summary generation task payload

type SyncCursor 

type SyncCursor struct {
	// Timestamp of last sync
	LastSyncTime time.Time `json:"last_sync_time"`

	// Connector-specific cursor (e.g., pagination token, offset, etc.)
	ConnectorCursor map[string]interface{} `json:"connector_cursor"`

	// Hash of the last full sync to detect schema changes
	LastSchemaHash string `json:"last_schema_hash"`
}

SyncCursor represents the position/state for incremental sync Connector-specific structure allows flexibility

func (*SyncCursor) ToJSON 

func (r *SyncCursor) ToJSON() (JSON, error)

type SyncItemError 

type SyncItemError struct {
	// Title is the document title (user content, not translated).
	Title string `json:"title,omitempty"`
	// Code is a stable key the frontend maps to a localized string, e.g.
	// "feishu_rate_limited" → datasource.syncError.feishu_rate_limited.
	Code string `json:"code,omitempty"`
	// Params are interpolation values for the localized string, e.g. {"code":"1663"}.
	Params map[string]string `json:"params,omitempty"`
	// Message is a human fallback used when the client has no i18n key for Code.
	Message string `json:"message,omitempty"`
}

SyncItemError is one user-facing failure sample. It carries a stable i18n Code (+ interpolation Params) so the frontend localises it to the viewer's language, plus a Message fallback for clients without the key. The raw API status/body/log_id is never stored here — that stays in the server logs.

func (SyncItemError) Display 

func (e SyncItemError) Display() string

Display renders the sample as a single plain string for server-side use (logs, fatal-error detail). The localised UI string is built on the frontend from Code/Params; this is only a non-localised fallback.

func (*SyncItemError) UnmarshalJSON 

func (e *SyncItemError) UnmarshalJSON(b []byte) error

UnmarshalJSON keeps old sync logs readable: historically each error was a plain JSON string, so a bare string decodes into Message.

type SyncLog

	// Items skipped (no changes detected)
	ItemsSkipped int `json:"items_skipped" extensions:"x-agent"`

	// Items that failed to sync
	ItemsFailed int `json:"items_failed" extensions:"x-agent"`

	// Error details if status is "failed"
	ErrorMessage string `json:"error_message"`

	// Detailed sync result (JSON-encoded)
	Result JSON `json:"result" gorm:"type:jsonb"`

	// Creation timestamp (usually same as StartedAt)

	// Items updated
	Updated int `json:"updated"`

	// Items deleted
	Deleted int `json:"deleted"`

	// Items skipped (no changes)
	Skipped int `json:"skipped"`

	// Items that failed
	Failed int `json:"failed"`

	// Deleted items whose KB deletion failed (a subset of Failed). Past the
	// connector cursor, so normally only a later full sync retries them.
	DeletionFailed int `json:"deletion_failed,omitempty"`

	// Per-item failure samples (capped), shown in the sync-log UI.
	Errors []SyncItemError `json:"errors,omitempty"`

	// Updated cursor for next incremental sync
	NextCursor *SyncCursor `json:"next_cursor,omitempty"`
}

SyncResult summarizes the outcome of a sync operation

func (*SyncResult) ToJSON 

func (r *SyncResult) ToJSON() (JSON, error)

ToJSON converts a value to JSON type

type SystemSetting 

type SystemSetting struct {

	ValueType string `gorm:"type:varchar(16);not null"  json:"value_type"`
	// Category groups settings in the management UI ("limits", "agent",

	Description string `gorm:"type:text;not null;default:''" json:"description"`
	// IsSecret reserves UI affordances for P3 (mask + reveal-with-confirm).

	IsSecret bool `gorm:"not null;default:false"  json:"is_secret"`
	// RequiresRestart reserves UI affordances for P3 (banner "this

	// `gorm:"-"` so GORM never tries to read/write the column.
	Enum []string `gorm:"-" json:"enum,omitempty"`

	// LastModifiedByName is a display label resolved from LastModifiedBy
	// (the user's UUID) at handler time — username when available,
	// otherwise email. Empty for virtual rows that were never persisted
	// (LastModifiedBy=""). Not stored: derived per request so renaming
	// a user reflects on the next reload without a backfill job.
	LastModifiedByName string `gorm:"-" json:"last_modified_by_name,omitempty"`
}

SystemSetting is a platform-wide (NOT workspace-scoped) tunable that SystemAdmins can edit at runtime via the management UI without restarting the service. Persisted in the system_settings table (migration 000053).

The 3-tier resolver in service.SystemSettingService reads in priority order: DB row > os.Getenv(EnvName) > built-in default. The Service owns the registry of legal keys + their default values + their ENV names; this type is just the on-disk shape.

Value is stored as JSONB so the same column can hold ints / strings / booleans / arrays. ValueType ("int" | "string" | "bool") tells callers (and the AsXxx helpers below) how to decode the raw bytes. Booleans roundtrip as `true`/`false`, ints as `42`, strings as `"foo"`.

func (*SystemSetting) AsBool 

func (s *SystemSetting) AsBool() (bool, error)

AsBool decodes the raw JSON value as a bool. Requires ValueType to be "bool"; the JSON must be `true` or `false`.

func (*SystemSetting) AsInt 

func (s *SystemSetting) AsInt() (int64, error)

AsInt decodes the raw JSON value as an int64. Returns an error if ValueType is not "int" or the JSON does not parse as a number.

Accepts both `42` (number literal) and `"42"` (quoted string) so hand-edited DB rows are tolerated. The service-layer Update path always writes a number literal.

func (*SystemSetting) AsString 

func (s *SystemSetting) AsString() (string, error)

AsString decodes the raw JSON value as a string. Requires ValueType to be "string"; the JSON must be a JSON string ("foo"), not a number or object.

func (*SystemSetting) AsStringList 

func (s *SystemSetting) AsStringList() ([]string, error)

AsStringList decodes the raw JSON value as []string. Requires ValueType to be "string_list"; the JSON must be a JSON array of strings, e.g. `["example.com", "*.foo.bar", "10.0.0.0/8"]`.

Returns an empty (non-nil) slice for an empty list, so callers can treat the absence of items uniformly and still iterate without nil checks.

func (SystemSetting) TableName 

func (SystemSetting) TableName() string

TableName pins the schema to migration 000053 — GORM's default pluralisation would yield "system_settings" anyway, but spelling it out shields against future renames.

type SystemSettingSummary added in v0.9.0 

type SystemSettingSummary struct {
	Key             string   `json:"key"                  extensions:"x-agent"`
	ValueJSON       string   `json:"value_json,omitempty" extensions:"x-agent,x-agent-max-runes=4096"`
	ValueHidden     bool     `json:"value_hidden"         extensions:"x-agent"`

	Description     string   `json:"description"          extensions:"x-agent"`
	RequiresRestart bool     `json:"requires_restart"     extensions:"x-agent"`
	Enum            []string `json:"enum,omitempty"       extensions:"x-agent"`
}

	Endpoint       string `json:"endpoint"`
	Region         string `json:"region"`
	AccessKey      string `json:"access_key"`
	SecretKey      string `json:"secret_key"`

	PathPrefix     string `json:"path_prefix"`
	TempBucketName string `json:"temp_bucket_name"`
	TempRegion     string `json:"temp_region"`
}

TOSEngineConfig is for Volcengine TOS (火山引擎对象存储).

type TagReferenceCounts 

type TagReferenceCounts struct {
	KnowledgeCount int64
	ChunkCount     int64
}

TagReferenceCounts holds the reference counts for a tag.

type TagScope 

type TagScope struct {
	KnowledgeBaseID string   `json:"knowledge_base_id"`
	TagIDs          []string `json:"tag_ids"`
}

TagScope represents a tag-constrained retrieval scope inside one knowledge base.

type TaskDeadLetter 

type TaskDeadLetter struct {
	// Auto-increment row id.
	ID int64 `json:"id" gorm:"primaryKey;autoIncrement"`
	// Tenant scope mirrored from the original task payload (best-effort:
	// if the middleware can't decode the payload, this falls back to 0).
	TenantID uint64 `json:"tenant_id" gorm:"index"`
	// Task identifier (e.g. "wiki:ingest", "summary:generation").
	TaskType string `json:"task_type" gorm:"type:varchar(64)"`
	// Logical scope, mirrors task_pending_ops.scope. Falls back to
	// "unknown" when the middleware doesn't recognize the task type's
	// payload.
	Scope string `json:"scope" gorm:"type:varchar(32)"`
	// Identifier within scope, e.g. kbID for scope="knowledge_base".
	ScopeID string `json:"scope_id" gorm:"type:varchar(64)"`
	// Optional secondary identifier. Wiki ingest uses this for the
	// knowledge_id so per-document failures cluster around the source
	// document; other consumers can leave it empty.
	RelatedID string `json:"related_id" gorm:"type:varchar(64);default:''"`
	// Raw task payload at the time of failure. For asynq tasks this is
	// the verbatim asynq.Task.Payload(); for service-level dead letters
	// the consumer chooses what to record.
	Payload json.RawMessage `json:"payload" gorm:"type:jsonb"`
	// String form of the final error. Long stack traces are kept verbatim.
	LastError string `json:"last_error" gorm:"type:text;default:''"`
	// Total attempt count when the dead-letter record was written.
	FailCount int `json:"fail_count"`
	// Server-side write time.
	FailedAt time.Time `json:"failed_at"`
}

TaskDeadLetter is one row in the `task_dead_letters` archive: a permanent record of a task whose retry budget was exhausted. The table is populated from two distinct paths:

  1. The asynq dead-letter middleware (internal/middleware/asynq_dead_letter.go) inserts a row whenever an asynq task's retry count equals its MaxRetry on the way out. This is the catch-all that covers every registered task type uniformly without per-handler instrumentation.

  2. Service-level retry handlers insert directly when an in-batch retry counter exceeds the service-defined cap. Wiki ingest is the primary example: per-document ops accumulate fail_count in `task_pending_ops`, and once the count exceeds wikiMaxFailRetries the op is moved here instead of being requeued.

Operators query by (Scope, ScopeID) — e.g. "all dead letters for KB abc" — or by TaskType — e.g. "all summary:generation failures in the last 24h". The table has no TTL; rows are kept until manually pruned.

func (TaskDeadLetter) TableName 

func (TaskDeadLetter) TableName() string

TableName binds TaskDeadLetter to the `task_dead_letters` table.

type TaskInitiator 

type TaskInitiator struct {
	UserID     string     `json:"user_id,omitempty"`
	Role       TenantRole `json:"role,omitempty"`
	APIKeyID   uint64     `json:"api_key_id,omitempty"`
	APIKeyName string     `json:"api_key_name,omitempty"`
	// Agent is set when the task was submitted by an agent acting for UserID.
	Agent *AuditAgentAction `json:"agent,omitempty"`
}

TaskInitiator is the authenticated caller that submitted an asynchronous task. Workers restore it into their context so audit entries describe who initiated the operation, while tasks created by schedulers remain attributable to the system.

func TaskInitiatorFromContext 

func TaskInitiatorFromContext(ctx context.Context) TaskInitiator

TaskInitiatorFromContext snapshots the real caller identity for a task payload. Synthetic API-key users are service identities, not people, and are intentionally left empty so the activity feed presents them as system work. The API key id/name is still captured so workers can attribute activity.

func (TaskInitiator) Apply 

func (i TaskInitiator) Apply(ctx context.Context) context.Context

Apply restores a captured task initiator onto a worker context. Empty or legacy payloads are a no-op and therefore retain the system-task fallback. API key identity is restored for audit display only — not as TenantAPIKeyScope.

type TaskPendingOp 

type TaskPendingOp struct {
	// Auto-increment row id. Tie-break for PeekBatch / ClaimBatch
	// after fail_count, and the row key for DeleteByIDs / IncrFailCount.
	ID int64 `json:"id" gorm:"primaryKey;autoIncrement"`
	// Tenant scope mirrored from the enclosing object so per-tenant
	// retention / quota queries don't have to join.
	TenantID uint64 `json:"tenant_id" gorm:"index"`
	// Free-form task identifier (e.g. "wiki:ingest"). Should match an
	// asynq task type when applicable, but the queue itself doesn't
	// enforce that — it's just a string.
	TaskType string `json:"task_type" gorm:"type:varchar(64)"`
	// Logical scope, e.g. "knowledge_base" / "knowledge" / "tenant".
	// Read together with ScopeID.
	Scope string `json:"scope" gorm:"type:varchar(32)"`
	// Identifier within the scope (e.g. kbID for scope="knowledge_base").
	ScopeID string `json:"scope_id" gorm:"type:varchar(64)"`
	// Operation kind. Service-defined: e.g. "ingest" / "retract" for
	// wiki, but other consumers can use whatever vocabulary they like.
	Op string `json:"op" gorm:"type:varchar(32)"`
	// Optional service-defined deduplication key. The consumer is
	// responsible for collapsing equivalent ops within a peeked batch
	// (the queue itself does NOT enforce uniqueness — multiple rows with
	// the same DedupKey can coexist; the consumer chooses which wins).
	DedupKey string `json:"dedup_key" gorm:"type:varchar(128);default:''"`
	// JSON-serialized op payload. Schema is consumer-defined; the queue
	// stores it verbatim. Use json.RawMessage to avoid double-decode.
	Payload json.RawMessage `json:"payload" gorm:"type:jsonb;default:'{}'"`
	// In-batch retry counter. Reset to 0 on successful consume.
	FailCount int `json:"fail_count" gorm:"default:0"`
	// Server-side enqueue time. NOT used for ordering (id is the cursor)
	// but useful for ops queries like "rows older than 1h that never
	// drained".
	EnqueuedAt time.Time `json:"enqueued_at"`
	// Optional claim timestamp for future locking workflows. Not used
	// in the current revision: consumers rely on external mutual
	// exclusion (e.g. wiki:active:<kbID> Redis SetNX). Reserved column
	// so future no-lock parallel workers can flip it inside a row-level
	// lock without another migration.
	ClaimedAt *time.Time `json:"claimed_at,omitempty"`
}

TaskPendingOp is one entry in the generic task pending queue (`task_pending_ops`). The queue is the durable replacement for the Redis-list-backed `wiki:pending:<kbID>` queue: rows survive restarts and are not subject to TTL eviction.

The (TaskType, Scope, ScopeID) tuple is the queue identity. A consumer pulls a batch with PeekBatch on that tuple, deduplicates by DedupKey service-side if it cares, processes the ops, then DeleteByIDs the consumed rows. FailCount is incremented per-row by IncrFailCount and the consumer dead-letters the row once the count exceeds a service- defined cap.

func (TaskPendingOp) TableName 

func (TaskPendingOp) TableName() string

TableName binds TaskPendingOp to the `task_pending_ops` table.

type TemporaryDocument 

type TemporaryDocument struct {
	ID                string         `json:"id" gorm:"type:varchar(36);primaryKey"`

	// AcceptedCount counts how many users have completed registration
	// through this invitation. Per-user invitations cap out at 1 (and
	// the row flips to accepted in the same step). Share-link rows can

	// "已加入 N 人" caption so Owners can see whether a link is fresh
	// or has already been used widely.
	AcceptedCount int `json:"accepted_count" gorm:"column:accepted_count;not null;default:0"`
}

TenantInvitation is one pending or finalised invitation issued by an Owner of `TenantID` to the user identified by `InviteeUserID`. The row is created in `pending` state when the Owner clicks "invite"; it flips to a terminal state when the invitee accepts/declines, the Owner revokes, or the row expires.

A tenant_members row is created only on accept; the invitation table is therefore the single source of truth for "pending intent" without polluting the authoritative member roster.

func (*TenantInvitation) IsExpired 

func (inv *TenantInvitation) IsExpired(at time.Time) bool

IsExpired reports whether this invitation is past its expires_at at the given reference time. The service layer uses this both for the lazy sweep and to reject an accept/decline arriving after timeout.

func (TenantInvitation) TableName 

func (TenantInvitation) TableName() string

TableName binds TenantInvitation to the tenant_invitations table.

type TenantInvitationResponse 

type TenantInvitationResponse struct {
	ID            uint64                 `json:"id"`
	TenantID      uint64                 `json:"tenant_id"`
	TenantName    string                 `json:"tenant_name,omitempty"`
	InviteeUserID string                 `json:"invitee_user_id"`
	InviteeEmail  string                 `json:"invitee_email,omitempty"`
	InviteeName   string                 `json:"invitee_name,omitempty"`
	InvitedBy     *string                `json:"invited_by,omitempty"`

	RespondedAt   *time.Time             `json:"responded_at,omitempty"`
	CreatedAt     time.Time              `json:"created_at"`
	// InviteURL is set on share-link rows that are still pending.
	// Composed by the handler from FrontendBaseURL + the row's plaintext
	// token, so the management UI can render a "copy link" button per

	InviteURL string `json:"invite_url,omitempty"`
	// IsShareLink is a convenience flag so the SPA doesn't have to
	// special-case "invitee_user_id == ”" everywhere when distinguishing
	// share-link rows from per-user invitations.
	IsShareLink bool `json:"is_share_link,omitempty"`
	// AcceptedCount mirrors TenantInvitation.AcceptedCount. Surfaced
	// for share-link rows so the management UI can show "N 人已通过此
	// 链接加入"; informational only for per-user invitations.
	AcceptedCount int `json:"accepted_count,omitempty"`
}

TenantInvitationResponse is the API projection joined with tenant name and inviter / invitee user fields the UI needs. The model is intentionally NOT serialised directly so we don't leak DeletedAt / UpdatedAt and lock the DB schema into the public API.

type TenantInvitationStatus 

type TenantInvitationStatus string

TenantInvitationStatus enumerates the lifecycle states of a single invitation row. The legal transitions are: 

pending -> accepted | declined | revoked | expired

All non-pending states are terminal; once a row leaves pending it is kept for the audit trail and a new pending row can be issued. 

const (
	// TenantInvitationStatusPending is the initial state: the invitee
	// has not yet acted and the row has not been revoked or aged out.
	TenantInvitationStatusPending TenantInvitationStatus = "pending"
	// TenantInvitationStatusAccepted means the invitee confirmed and
	// a corresponding active tenant_members row has been created in
	// the same transaction.
	TenantInvitationStatusAccepted TenantInvitationStatus = "accepted"
	// TenantInvitationStatusDeclined means the invitee rejected the
	// invitation. The row stays for auditability; a new pending
	// invitation can be issued afterwards.
	TenantInvitationStatusDeclined TenantInvitationStatus = "declined"
	// TenantInvitationStatusRevoked means a tenant Owner cancelled
	// the pending invitation before the invitee acted.
	TenantInvitationStatusRevoked TenantInvitationStatus = "revoked"
	// TenantInvitationStatusExpired means the row outlived its
	// expires_at without being accepted/declined/revoked. Set by the
	// lazy-sweep run before every List/Accept/Decline.
	TenantInvitationStatusExpired TenantInvitationStatus = "expired"
)

func (TenantInvitationStatus) IsTerminal 

func (s TenantInvitationStatus) IsTerminal() bool

IsTerminal reports whether s is a non-pending state. Used by the service layer to short-circuit accept/decline/revoke on rows that have already been finalised.

type TenantInviteCandidate 

type TenantInviteCandidate struct {
	TenantID               uint64 `json:"tenant_id"`
	TenantName             string `json:"tenant_name"`
	RepresentativeUserID   string `json:"representative_user_id"`
	RepresentativeUsername string `json:"representative_username"`
	RepresentativeEmail    string `json:"representative_email"`
	RepresentativeAvatar   string `json:"representative_avatar,omitempty"`
}

TenantInviteCandidate is one row in the search-tenants-for-invite picker. Plan 3 invites a tenant; users serve as labels. We surface the tenant identity together with a "representative" user (the matching user that caused this tenant to show up in the search). Multiple users may belong to the same tenant; deduplication is by TenantID.

type TenantMember 

type TenantMember struct {
	// Surrogate primary key.
	ID uint64 `json:"id" gorm:"primaryKey;autoIncrement"`
	// UserID references users.id. Together with TenantID forms the logical
	// key enforced by the partial unique index uniq_user_tenant.
	UserID string `json:"user_id" gorm:"type:varchar(36);not null;index"`
	// TenantID references tenants.id.
	TenantID uint64 `json:"tenant_id" gorm:"not null;index"`
	// Role held by the user inside this tenant.
	Role TenantRole `json:"role" gorm:"type:varchar(20);not null;default:'contributor'"`
	// Status controls whether this membership is honoured by the auth
	// middleware; see TenantMemberStatus constants.
	Status TenantMemberStatus `json:"status" gorm:"type:varchar(20);not null;default:'active'"`
	// InvitedBy records the user ID of the admin who created this row via
	// an invitation flow. Nil for rows created by self-service registration.
	InvitedBy *string `json:"invited_by,omitempty" gorm:"type:varchar(36)"`
	// JoinedAt is when the membership became active.
	JoinedAt  time.Time      `json:"joined_at"`
	CreatedAt time.Time      `json:"created_at"`
	UpdatedAt time.Time      `json:"updated_at"`
	DeletedAt gorm.DeletedAt `json:"deleted_at" gorm:"index"`
}

TenantMember represents the (user, tenant) membership record that carries the user's TenantRole for that specific tenant.

A user has one TenantMember row per tenant they belong to. The home tenant recorded on User.TenantID is always one of these rows; additional rows are created when an admin adds the user to another tenant.

func (TenantMember) TableName 

func (TenantMember) TableName() string

TableName binds TenantMember to the tenant_members table.

type TenantMemberResponse 

type TenantMemberResponse struct {
	UserID    string             `json:"user_id" extensions:"x-agent"`
	Email     string             `json:"email" extensions:"x-agent"`
	Username  string             `json:"username" extensions:"x-agent"`
	Avatar    string             `json:"avatar,omitempty"`
	Role      TenantRole         `json:"role" extensions:"x-agent"`
	Status    TenantMemberStatus `json:"status" extensions:"x-agent"`
	InvitedBy *string            `json:"invited_by,omitempty"`
	JoinedAt  time.Time          `json:"joined_at" extensions:"x-agent"`
}

TenantMemberResponse is the API projection of a TenantMember row joined with the human-facing user fields the management UI needs (email, username, avatar). It is intentionally NOT the GORM model: returning the model directly would leak DeletedAt/UpdatedAt and lock the DB schema into the public API. Use this for `/tenants/:id/members` only.

type TenantMemberStatus 

type TenantMemberStatus string

TenantMemberStatus enumerates the lifecycle states of a membership row. 

const (
	// TenantMemberStatusActive is the normal membership state; the user
	// can authenticate into the tenant and is subject to their role.
	TenantMemberStatusActive TenantMemberStatus = "active"
	// TenantMemberStatusInvited represents a pending invitation that has
	// not yet been accepted. The auth middleware treats this as "not a
	// member" until the status flips to active.
	TenantMemberStatusInvited TenantMemberStatus = "invited"
	// TenantMemberStatusSuspended is an admin-revoked membership. The
	// row is preserved for audit trail but the user cannot authenticate
	// into the tenant.
	TenantMemberStatusSuspended TenantMemberStatus = "suspended"
)

type TenantProvisioningMode 

type TenantProvisioningMode string

TenantProvisioningMode controls what UserService.Register does after it has validated the identity fields. Joining an existing tenant is orchestrated by the invitation handler because the invitation token is the authority for the target tenant and role. 

const (
	TenantProvisioningCreatePersonal TenantProvisioningMode = "create_personal"
	TenantProvisioningTenantless     TenantProvisioningMode = "tenantless"
)

func (TenantProvisioningMode) IsValid 

func (m TenantProvisioningMode) IsValid() bool

type TenantRole 

type TenantRole string

TenantRole represents a user's role inside a single tenant.

Tenant roles govern intra-tenant authority (who can create/edit/delete resources, manage tenant settings, etc.) and are orthogonal to the OrgMemberRole defined in organization.go, which governs cross-tenant sharing. A user may therefore carry different TenantRole values in different tenants (one TenantMember row per (user, tenant) pair). 

const (
	// TenantRoleOwner has full control over the tenant, including tenant
	// deletion, ownership transfer, and managing tenant API keys.
	TenantRoleOwner TenantRole = "owner"
	// TenantRoleAdmin manages users, integrations, and tenant-scoped
	// configuration such as model providers, vector stores, MCP services
	// and IM channels, but cannot delete the tenant or change Owners.
	TenantRoleAdmin TenantRole = "admin"
	// TenantRoleContributor can create knowledge bases and agents, and edit
	// the ones they created. They have read access to everything else in
	// the tenant.
	TenantRoleContributor TenantRole = "contributor"
	// TenantRoleViewer has read-only access to tenant resources and can
	// run agents that are explicitly marked as runnable by viewers.
	TenantRoleViewer TenantRole = "viewer"
)

func TenantRoleFromContext 

func TenantRoleFromContext(ctx context.Context) TenantRole

TenantRoleFromContext extracts the caller's TenantRole in the currently active tenant. Returns TenantRoleViewer when the key is absent so that callers fail closed (least privilege) if the auth middleware did not populate the role for some reason.

func (TenantRole) HasPermission 

func (r TenantRole) HasPermission(required TenantRole) bool

HasPermission reports whether r is at least as privileged as required. Used by RequireRole-style middleware to gate endpoints.

func (TenantRole) IsValid 

func (r TenantRole) IsValid() bool

IsValid reports whether r is one of the four defined tenant roles.

func (TenantRole) Level 

func (r TenantRole) Level() int

Level returns the numeric privilege level of the role. Unknown roles return 0, which is strictly less than any defined role.

type TenantSandboxConfig 

type TenantSandboxConfig struct {
	// SandboxType is cube, e2b, or docker; disabled is the hidden policy row.
	SandboxType string `json:"sandbox_type,omitempty"`

	// DefaultTimeoutSec is the per-execution timeout in seconds. 0 uses the
	// program's built-in default.
	DefaultTimeoutSec int `json:"default_timeout_sec,omitempty"`

	// TerminalIdleDisconnectSec is how long an interactive terminal or
	// desktop may go without user activity before WeKnora closes the
	// connection so the sandbox can pause on its provider TTL. Terminal
	// counts keystrokes and PTY output; desktop counts mouse and keyboard.
	// 0 uses the built-in default (15 minutes). Not an identity field.
	TerminalIdleDisconnectSec int `json:"terminal_idle_disconnect_sec,omitempty"`

	// DesktopEnabled declares that this config's base template is a desktop
	// image (XFCE + x11vnc + websockify). It is NOT a second template: a
	// config has exactly one boot target, and skill snapshots stack on top of
	// this base generation after generation. Flipping it changes the base, so
	// any installed skills must be rebuilt from the new one.
	DesktopEnabled bool `json:"desktop_enabled,omitempty"`

	// AllowPrivateEndpoints permits this workspace config to reach RFC1918 or
	// loopback cluster endpoints. Link-local/cloud-metadata addresses remain
	// blocked. It is explicit in the UI instead of hidden in process env.
	AllowPrivateEndpoints bool `json:"allow_private_endpoints,omitempty"`

	// EnvVars are additional environment variables injected into every
	// sandbox created for this tenant. 🔒 Values are encrypted at rest.
	// These become visible to all scripts running in the tenant's
	// sandboxes — do not place secrets here that scripts must not access.
	EnvVars map[string]string `json:"env_vars,omitempty"`

	// VolumeMount configures an optional shared volume mounted into every
	// sandbox created for this tenant. Currently used for tenant-installed
	// skills, but the configuration itself is skill-agnostic and can serve
	// any volume-mount use case (shared datasets, pre-installed toolchains,
	// etc.).
	VolumeMount *VolumeMountConfig `json:"volume_mount,omitempty"`

	// SkillImage points at the snapshot that carries this config's installed
	// skills. Empty means "use the base template". Written only by the skill
	// install/remove path: MergeSandboxConfigForUpdate ignores client values
	// so a settings-form save cannot wipe or plant the pointer.
	SkillImage *SkillImageConfig `json:"skill_image,omitempty"`

	// SkillRollout decides whether sessions that already hold a sandbox of
	// this config rebuild after a skill install or removal. Empty and
	// SkillRolloutNextTurn rebuild on the next chat turn. SkillRolloutNewSession
	// leaves those sandboxes on the previous image; only sessions that start
	// afterwards boot the new snapshot.
	// User allocation always keeps existing shared machines, regardless of this setting.
	SkillRollout string `json:"skill_rollout,omitempty"`

	// AllocationMode decides how a session that has not yet used a sandbox
	// of this config is placed: "session" (default) gives it a machine of its
	// own, "user" lets one verified owner's sessions share a machine. A
	// session never changes mode after its first use; see
	// internal/sandbox/allocation.
	AllocationMode string `json:"allocation_mode,omitempty"`

	// UserSandboxEmptyRetentionDays is how long a user machine with no live
	// session is kept before the reclaim job deletes it. 0 means the default
	// (7); values above 90 are rejected.
	UserSandboxEmptyRetentionDays int `json:"user_sandbox_empty_retention_days,omitempty"`

	// Network is the outbound/inbound network policy applied to every sandbox
	// created from this config — chat sessions, skill installs and deep
	// connectivity probes alike. nil and the zero value mean the same thing:
	// outbound egress allowed, inbound public access closed.
	Network *SandboxNetworkPolicy `json:"network,omitempty"`

	Cube   *CubeSandboxConfig   `json:"cube,omitempty"`
	E2B    *E2BSandboxConfig    `json:"e2b,omitempty"`
	Docker *DockerSandboxConfig `json:"docker,omitempty"`
}

TenantSandboxConfig is one named sandbox backend a workspace maintains.

It is self-contained: provider fields are not inherited from process environment. Leaving a required provider field empty is rejected on save.

func MergeSandboxConfigForUpdate 

func MergeSandboxConfigForUpdate(incoming, existing *TenantSandboxConfig) *TenantSandboxConfig

MergeSandboxConfigForUpdate resolves redacted placeholders in incoming against the currently stored config, so a client that never received the real secret can submit the rest of the form without wiping it. Pointers the editor does not own (SkillImage, VolumeMount) are kept from existing.

func SandboxConfigForResponse 

func SandboxConfigForResponse(cfg *TenantSandboxConfig, maskSecrets bool) *TenantSandboxConfig

SandboxConfigForResponse returns a copy of cfg safe to serialize into an API response. When maskSecrets is true every secret-bearing field is replaced with RedactedSecretPlaceholder. Unset secrets stay empty so the UI can tell "configured" apart from "not configured".

func (*TenantSandboxConfig) RebuildsExistingOnSkillChange 

func (c *TenantSandboxConfig) RebuildsExistingOnSkillChange() bool

RebuildsExistingOnSkillChange reports whether an install or removal should mark already-bound sandboxes stale. Shared user machines always keep their current image. Unknown rollout values retain the per-session rebuild default.

func (*TenantSandboxConfig) Scan 

func (c *TenantSandboxConfig) Scan(value interface{}) error

Scan implements the sql.Scanner interface. Secrets that cannot be decrypted (missing or rotated SYSTEM_AES_KEY) are blanked and logged rather than failing the whole load, matching ModelParameters.Scan — a tenant must stay listable even if its sandbox credentials became unreadable.

func (*TenantSandboxConfig) Value 

func (c *TenantSandboxConfig) Value() (driver.Value, error)

Value implements the driver.Valuer interface. Every secret-bearing field (Cube.APIKey, E2B.APIKey, all EnvVars values, and injected header values) is encrypted before persisting. EnvVars are included because environment variables routinely carry credentials, and their values are handed to tenant scripts verbatim. The receiver is never mutated: nested structs and the map are copied first.

type TenantSandboxConfigEntity 

type TenantSandboxConfigEntity struct {
	ID          string `gorm:"type:varchar(36);primaryKey"`
	TenantID    uint64 `gorm:"index"`
	Name        string `gorm:"type:varchar(255);not null"`
	Description string `gorm:"type:text"`

	// SandboxType is promoted out of Config so listing and cleanup decisions
	// do not have to decrypt and unmarshal the payload.
	SandboxType string `gorm:"type:varchar(32);not null"`

	Config *TenantSandboxConfig `gorm:"type:jsonb"`

	// CordonedAt is held while identity fields are being changed. See
	// IsCordoned: it is a lease, never a permanent lock.
	CordonedAt *time.Time

	CreatedAt time.Time
	UpdatedAt time.Time
	DeletedAt gorm.DeletedAt `gorm:"index"`
}

TenantSandboxConfigEntity is one named sandbox backend configuration.

func (*TenantSandboxConfigEntity) IsCordoned 

func (e *TenantSandboxConfigEntity) IsCordoned(now time.Time, lease time.Duration) bool

IsCordoned reports whether sandbox resolution must be refused for this config right now.

func (*TenantSandboxConfigEntity) TableName 

func (e *TenantSandboxConfigEntity) TableName() string

TableName pins the table so GORM's pluralizer cannot drift.

type TenantSkillCatalogEntity 

type TenantSkillCatalogEntity struct {
	ID           string `gorm:"type:varchar(36);primaryKey"`
	TenantID     uint64
	Name         string `gorm:"type:varchar(255);not null"`
	Version      string `gorm:"type:varchar(64)"`
	Description  string `gorm:"type:text"`
	Instructions string `gorm:"type:text"`
	// BundleRef locates the one stored zip for this definition. Install rows
	// do not own a copy: sandbox uninstall must not delete this object.
	BundleRef    string `gorm:"type:varchar(1024)"`
	BundleSHA256 string `gorm:"type:varchar(64)"`
	CreatedAt    time.Time
	UpdatedAt    time.Time
	DeletedAt    gorm.DeletedAt
}

TenantSkillCatalogEntity is one workspace skill definition. It does not belong to a sandbox: installations onto a config's image are TenantSkillEntity rows that point back here.

func (*TenantSkillCatalogEntity) TableName 

func (e *TenantSkillCatalogEntity) TableName() string

TableName pins the table so GORM's pluralizer cannot drift.

type TenantSkillEntity 

type TenantSkillEntity struct {
	// ID is the row key. It is not the directory name inside the image.
	ID              string `gorm:"type:varchar(36);primaryKey"`
	TenantID        uint64
	SandboxConfigID string `gorm:"type:varchar(36)"`
	// CatalogID points at the tenant-level skill definition this install
	// was created from. Empty on rows that predate the catalog migration
	// and have not been backfilled yet.
	CatalogID string `gorm:"type:varchar(36);index"`

	// Name is the SKILL.md frontmatter name and the directory under

	Version     string `gorm:"type:varchar(64)"`
	Description string `gorm:"type:text"`
	// Instructions is the SKILL.md body (level 2 disclosure).
	Instructions string `gorm:"type:text"`

	// BundleRef is a leftover locator from when each install owned a zip.
	// New installs leave this empty: the catalog row owns the archive, and

	BundleSHA256 string `gorm:"type:varchar(64)"`

	// Enabled controls visibility to the agent only. The files stay in the
	// image either way; removal is a separate flow that rebuilds the snapshot.
	Enabled bool `gorm:"default:true"`

	// InstalledSnapshotID is the snapshot produced by this skill's install,
	// kept for audit and chain troubleshooting.
	InstalledSnapshotID string `gorm:"type:varchar(255)"`

	// InstallSessionID / InstallMessageID locate the installer agent's
	// transcript for the most recent install of this skill. A re-install
	// overwrites them: the previous run's conversation is superseded by the

	InstallSessionID string `gorm:"type:varchar(36)"`
	InstallMessageID string `gorm:"type:varchar(36)"`

	// Envs is the installer agent's declaration of the environment variables

	Envs SkillEnvVars `json:"envs,omitempty" gorm:"type:jsonb"`

	// Served is the version the live image still carries while a newer install
	// of this skill is in flight or has failed. The fields above describe the

}

TenantSkillEntity is one skill installed onto one sandbox config.

There is deliberately no entry_script / interpreter / smoke_command column: a skill may ship several executables across languages, so none of those is a single value. The interpreter is derived from the on-image path convention at execution time instead (see skills.Manager).

func (*TenantSkillEntity) ServedView 

func (e *TenantSkillEntity) ServedView() *TenantSkillEntity

ServedView is the row as the agent should see it: the row itself when it is ready, the version the image still carries while a newer install is in flight or has failed, and nil when the image serves nothing of this skill.

The view is a copy marked ready, so every reader downstream of the usable set - discovery, instructions, resource files - answers from the served version without knowing an upgrade exists. Enabled and Envs stay the row's own: an administrator's switch and stored values apply to whichever version is running.

func (*TenantSkillEntity) TableName 

func (e *TenantSkillEntity) TableName() string

TableName pins the table so GORM's pluralizer cannot drift.

type TenantSkillSnapshotEntity 

type TenantSkillSnapshotEntity struct {
	// ID is the install ID; it also seeds the snapshot name.
	ID              string `gorm:"type:varchar(36);primaryKey"`
	TenantID        uint64 `gorm:"index"`
	SandboxConfigID string `gorm:"type:varchar(36);index"`
	SkillID         string `gorm:"type:varchar(36);index"`

	SnapshotID       string `gorm:"type:varchar(255)"`
	ParentSnapshotID string `gorm:"type:varchar(255)"`
	Generation       int

	// PlannedName is the name handed to CreateSnapshot. It is written before
	// the provider call, which is what makes an abandoned build identifiable:
	// SnapshotID can only be recorded once the provider has answered, so a
	// process that died in between left a snapshot the ledger could not name
	// and therefore could never reclaim. Matching is by name because only
	// Docker's ID is derivable from it; Cube and E2B mint their own and echo
	// the name back in the listing.
	PlannedName string `gorm:"type:varchar(255)"`

	Trigger string `gorm:"type:varchar(16)"`
	State   string `gorm:"type:varchar(16);index"`

	SupersededAt *time.Time
	CreatedAt    time.Time
	UpdatedAt    time.Time
}

TenantSkillSnapshotEntity is the image-chain ledger. It exists because snapshots are billable provider resources whose IDs we hand out: we must be able to say which generation came from which parent, and never leave a snapshot nobody knows about.

func (*TenantSkillSnapshotEntity) TableName 

func (e *TenantSkillSnapshotEntity) TableName() string

TableName pins the table so GORM's pluralizer cannot drift.

type TenantUserEnvVar 

type TenantUserEnvVar struct {
	ID       string `gorm:"type:varchar(36);primaryKey"`
	TenantID uint64 `` /* 126-byte string literal not displayed */

	// endpoint can leak it by forgetting to strip it.
	Value string `json:"-" gorm:"type:text"`

	CreatedAt time.Time
	UpdatedAt time.Time
}

TenantUserEnvVar is one principal's own environment variable.

An empty SkillID means the variable belongs to the whole sandbox config and is injected into every execution on it. A non-empty SkillID scopes it to that skill's declaration, injected only when a tool names the skill. The storage is the same either way; only the load timing differs.

It is keyed by principal rather than user id because the IM path puts a synthetic "system-<tenantID>" account in the user id, which would make every IM user of a workspace share a single credential.

func (*TenantUserEnvVar) AfterFind 

func (e *TenantUserEnvVar) AfterFind(tx *gorm.DB) error

func (*TenantUserEnvVar) BeforeCreate 

func (e *TenantUserEnvVar) BeforeCreate(tx *gorm.DB) error

func (*TenantUserEnvVar) BeforeSave 

func (e *TenantUserEnvVar) BeforeSave(tx *gorm.DB) error

func (TenantUserEnvVar) TableName 

func (TenantUserEnvVar) TableName() string

TableName pins the table so GORM's pluralizer cannot drift.

type TokenUsage 

type TokenUsage struct {
	PromptTokens     int `json:"prompt_tokens"`
	CompletionTokens int `json:"completion_tokens"`
	TotalTokens      int `json:"total_tokens"`
	// CachedTokens is the legacy alias for CacheReadTokens. It remains on the
	// wire for compatibility with existing API consumers.
	CachedTokens     int               `json:"cached_tokens,omitempty"`
	CacheReadTokens  int               `json:"cache_read_tokens,omitempty"`
	CacheWriteTokens int               `json:"cache_write_tokens,omitempty"`
	CacheMissTokens  int               `json:"cache_miss_tokens,omitempty"`
	CacheReported    bool              `json:"cache_reported"`
	CacheStatus      PromptCacheStatus `json:"cache_status,omitempty"`
	// ContextTokenScale is provider prompt tokens per cl100k-estimated token,
	// measured over the turn's rounds. Persisted with the turn so the next
	// turn's history loading and first compaction check are calibrated before
	// any provider count of their own. Zero when the turn measured none.
	ContextTokenScale float64 `json:"context_token_scale,omitempty"`
}

TokenUsage holds token consumption statistics returned by the model API.

func (*TokenUsage) Accumulate 

func (u *TokenUsage) Accumulate(other TokenUsage)

Accumulate adds another call's usage into u, preserving the subset semantics: prompt/completion/total and every cache counter sum independently (cache counters stay subsets of the prompt count and are never folded into it). CacheReported ORs, and the cache status is recomputed from the combined counters so a single cache hit anywhere in the accumulated calls reads as a hit.

func (*TokenUsage) MarkPromptCacheUnsupported 

func (u *TokenUsage) MarkPromptCacheUnsupported()

MarkPromptCacheUnsupported marks a provider/model path that cannot report provider-side prompt-cache usage.

func (TokenUsage) PromptCacheHitRate 

func (u TokenUsage) PromptCacheHitRate() float64

PromptCacheHitRate returns cache-read tokens as a percentage of the provider's prompt total. Zero when the prompt is empty. A ReAct turn that reuses the system prefix therefore reads as a high hit rather than a miss.

func (*TokenUsage) Scan 

func (u *TokenUsage) Scan(value interface{}) error

Scan restores a jsonb usage column; NULL leaves the receiver zero-valued.

func (*TokenUsage) SetPromptCacheUsage 

func (u *TokenUsage) SetPromptCacheUsage(read, write, miss int, reported bool)

SetPromptCacheUsage normalizes provider-specific cache counters into the shared usage model. promptTokens remains the provider's total input-token count; read/write/miss are descriptive subsets and must not be added to it.

func (*TokenUsage) Value 

func (u *TokenUsage) Value() (driver.Value, error)

Value persists the usage as a jsonb column (assistant messages carry the turn's aggregate); nil writes SQL NULL. Mirrors the nullable-pointer pattern APIPrincipalConfig uses.

type Tool 

type Tool interface {
	// Name returns the unique identifier for this tool
	Name() string

	// Description returns a human-readable description of what the tool does
	Description() string

	// Parameters returns the JSON Schema for the tool's parameters
	Parameters() json.RawMessage

	// Execute runs the tool with the given arguments
	Execute(ctx context.Context, args json.RawMessage) (*ToolResult, error)
}

Tool defines the interface that all agent tools must implement

	Grant      string `json:"grant,omitempty"`
	GrantScope string `json:"grant_scope,omitempty"`
	// GrantLapsed, when set, is why an earlier grant for this call no longer
	// applies (an AgentGrantLapse value).
	GrantLapsed string `json:"grant_lapsed,omitempty"`

	// may later allow the same call for its future runs.
	GrantRisk  string `json:"grant_risk,omitempty"`
	GrantLabel string `json:"grant_label,omitempty"`
}

ToolApprovalPromptRequest is the Request of an AgentPromptKindToolApproval.

	// AllowInSession approves later calls with the request's Grant too.
	AllowInSession bool `json:"allow_in_session,omitempty"`
	// Scope is "once" or "session" for Lite host approvals; empty means once.
	Scope string `json:"scope,omitempty"`
	// Access narrows a host grant to "read"; empty keeps the proposal.
	Access string `json:"access,omitempty"`
}

ToolApprovalPromptResponse is the Response of an AgentPromptKindToolApproval.

	Scope          string                `json:"scope,omitempty"`
}

ToolApprovalRecord is one human approval attached to an agent step.

type ToolCall 

type ToolCall struct {
	// Target identifies the actual proxy target; Name/Args retain the model call for replay.
	Target           *ToolCallTarget        `json:"target,omitempty"`
	ID               string                 `json:"id"`                          // Function call ID from LLM
	Name             string                 `json:"name"`                        // Tool name
	Args             map[string]interface{} `json:"args"`                        // Tool arguments

	ProviderMetadata ToolCallMetadata       `json:"provider_metadata,omitempty"` // Provider-specific tool-call state for replay
}

func (ToolCall) ExecutionArgs 

func (t ToolCall) ExecutionArgs() map[string]interface{}

ExecutionArgs returns the resolved target arguments without changing replay data.

func (ToolCall) ExecutionName 

func (t ToolCall) ExecutionName() string

ExecutionName returns the resolved target name for presentation and tracing.

type ToolCallMetadata 

type ToolCallMetadata map[string]json.RawMessage

ToolCallMetadata carries provider-specific tool-call state that must round-trip with the assistant tool call, without teaching core agent code vendor fields.

	Name        string                 `json:"name"`
	Args        map[string]interface{} `json:"args"`
	ServiceName string                 `json:"service_name"`
	ToolName    string                 `json:"tool_name"`
}

ToolCallTarget identifies a resolved invocation without rewriting the model's function call, which must be preserved for history replay and provider state.

type ToolResult 

type ToolResult struct {
	// OutputFiles holds sandbox references for this live result only. History
	// uses the final answer's persistent resource references instead.
	// A non-nil empty slice means output inspection found no eligible changes;
	// nil means no output inspection result is available.
	OutputFiles []string               `json:"-"`
	Success     bool                   `json:"success"`          // Whether the tool executed successfully

	Images      []string               `json:"images,omitempty"` // Base64 data URIs from tool (e.g. MCP image content)
	// ImageDescriptions is aligned with Images and holds a vision model's
	// description of each for a chat model that cannot view them ("" when an
	// image could not be described). Live only.
	ImageDescriptions []string `json:"-"`
	// ImageDetail ("brief" or "full") and ImageFocus carry how closely the
	// model asked to read Images when it cannot view them. Live only.
	ImageDetail string `json:"-"`
	ImageFocus  string `json:"-"`
	// Suspend, when set, means the call did not run: it is waiting on a user
	// prompt and the run must end so it can be resumed later. Live only.
	Suspend *PromptSuspension `json:"-"`
}

ToolResult represents the result of a tool execution

type TracingContext 

type TracingContext struct {
	// LangfuseTraceID is the id of the root trace that originated this task.
	// Kept for backward compatibility with legacy payloads; the OTLP path now
	// propagates correlation via LangfuseTraceparent (W3C) below.
	LangfuseTraceID string `json:"lf_trace_id,omitempty"`
	// LangfuseParentObservationID is retained for backward compatibility only;
	// the OTLP path no longer uses it (parent linking flows through the W3C
	// traceparent's parent span id).
	LangfuseParentObservationID string `json:"lf_parent_obs_id,omitempty"`
	// LangfuseTraceparent carries the W3C Trace Context (`traceparent` header
	// value: `00-<trace_id>-<span_id>-<flags>`) from the enqueuing request.
	// The worker re-extracts it so its spans are children of the same trace —
	// stitching the HTTP request and the async job into one LiteFuse tree. This
	// is also what propagates a sop3 run's W3C trace_id into any asynq jobs
	// WeKnora enqueues while serving sop3's agent-chat call.
	LangfuseTraceparent string `json:"lf_traceparent,omitempty"`
	// LangfuseUserID preserves the userId / tenant label across the async
	// boundary so that orphan async traces (when no upstream trace id is
	// available) still show up in the Langfuse "Users" view under the
	// right tenant.
	LangfuseUserID string `json:"lf_user_id,omitempty"`
	// LangfuseSessionID preserves the sessionId for the same reason.
	LangfuseSessionID string `json:"lf_session_id,omitempty"`
}

TracingContext is an embeddable struct that carries observability context (currently Langfuse trace/span ids plus user/session hints) across process boundaries — specifically, from an HTTP request into an asynq task payload and back out inside the worker.

It lives in the types package, not the langfuse package, so that:

  • asynq payload structs can embed it without pulling the langfuse package into every service/handler import graph;
  • the langfuse package can remain a leaf dependency that only types (and its own tests) reference directly.

The JSON tags all use the "lf_" prefix and omitempty so that payloads constructed before the Langfuse feature landed remain byte-compatible (empty fields collapse to nothing in the serialized output) and so that Langfuse-specific columns don't collide with business fields that may happen to be named similarly.

func (TracingContext) GetLangfuseTracing 

func (tc TracingContext) GetLangfuseTracing() TracingContext

GetLangfuseTracing returns a copy of the embedded TracingContext.

func (*TracingContext) SetLangfuseTracing 

func (tc *TracingContext) SetLangfuseTracing(other TracingContext)

SetLangfuseTracing overwrites the embedded TracingContext. Method is exported so helpers in internal/tracing/langfuse can populate it via the LangfuseTracingCarrier interface without reflection.

type URLNormMode 

type URLNormMode int

URLNormMode 定义 URL 归一化模式 

const (
	// URLRemove 完全移除 URL
	URLRemove URLNormMode = iota

	URLKeepDomain
	// URLKeepDomainAndPath 保留域名和路径
	URLKeepDomainAndPath
)

type UpdateMemberRoleRequest 

type UpdateMemberRoleRequest struct {
	Role OrgMemberRole `json:"role" binding:"required"`
}

UpdateMemberRoleRequest represents a request to update a member's role

type UpdateOrganizationRequest 

type UpdateOrganizationRequest struct {
	Name                   *string `json:"name" binding:"omitempty,min=1,max=255"`

	MemberLimit            *int    `json:"member_limit"`              // max members; 0=unlimited
}

UpdateOrganizationRequest represents a request to update an organization

type UpdateSharePermissionRequest 

type UpdateSharePermissionRequest struct {
	Permission OrgMemberRole `json:"permission" binding:"required"`
}

UpdateSharePermissionRequest represents a request to update share permission

type UsedMemories 

type UsedMemories []UsedMemory

UsedMemories is the persisted per-message list.

func UsedMemoriesFromItems 

func UsedMemoriesFromItems(items []*MemoryItem) UsedMemories

UsedMemoriesFromItems projects items into the client-facing shape.

func (*UsedMemories) Scan 

func (u *UsedMemories) Scan(value interface{}) error

func (UsedMemories) Value 

func (u UsedMemories) Value() (driver.Value, error)

type UsedMemory 

type UsedMemory struct {
	ID      string `json:"id"`
	Kind    string `json:"kind"`
	Content string `json:"content"`
}

UsedMemory is the per-turn record of which memories were injected. It is returned to the client so the chat UI can show, and let the user delete, exactly what influenced an answer.

func MergeUsedMemories 

func MergeUsedMemories(existing, additional []UsedMemory) []UsedMemory

MergeUsedMemories combines two lists of shown memories, keeping the first occurrence of each id.

A memory can influence a turn twice — once by shaping the search and once by being quoted in the answer — and the user should see it listed once.

type User 

type User struct {
	// Unique identifier of the user
	ID string `json:"id"         gorm:"type:varchar(36);primaryKey"`
	// Username of the user
	Username string `json:"username"   gorm:"type:varchar(100);uniqueIndex;not null"`

	// Whether the user is a system administrator (independent of workspace roles)
	IsSystemAdmin bool `json:"is_system_admin" gorm:"default:false;index"`
	// Per-user UI/feature preferences.
	// Stored as JSON (jsonb on Postgres, TEXT on SQLite) via the
	// driver.Valuer / sql.Scanner methods on UserPreferences.
	Preferences UserPreferences `json:"preferences" gorm:"type:jsonb;not null;default:'{}'"`
	// Creation time of the user
	CreatedAt time.Time `json:"created_at"`
	// Last updated time of the user
	UpdatedAt time.Time `json:"updated_at"`
	// Deletion time of the user
	DeletedAt gorm.DeletedAt `json:"deleted_at" gorm:"index"`

	// Association relationship, not stored in the database
	Tenant *Tenant `json:"tenant,omitempty" gorm:"foreignKey:TenantID"`
}

User represents a user in the system

func (*User) ToUserInfo 

func (u *User) ToUserInfo() *UserInfo

type UserInfo struct {
	ID                  string          `json:"id" extensions:"x-agent"`
	Username            string          `json:"username" extensions:"x-agent"`
	Email               string          `json:"email" extensions:"x-agent"`
	Avatar              string          `json:"avatar"`
	TenantID            uint64          `json:"tenant_id" extensions:"x-agent"`
	IsActive            bool            `json:"is_active" extensions:"x-agent"`
	CanAccessAllTenants bool            `json:"can_access_all_tenants"`
	IsSystemAdmin       bool            `json:"is_system_admin" extensions:"x-agent"`
	Preferences         UserPreferences `json:"preferences"`
	CreatedAt           time.Time       `json:"created_at" extensions:"x-agent"`
	UpdatedAt           time.Time       `json:"updated_at"`
}

UserInfo represents user information for API responses

type UserPreferences 

type UserPreferences struct {
	// BrowserSearchInstructions customizes browser search for this user. Nil/empty uses the platform default.
	BrowserSearchInstructions *string `json:"browser_search_instructions,omitempty"`

	// LastActiveTenantID remembers the last workspace the user actively
	// switched into, so a fresh login (new device, cleared browser, new
	// refresh token) lands them back in that workspace instead of always
	// bouncing to their home workspace. Written by the SPA's preferences
	// PUT and by service-level SwitchTenant (including when switching
	// home, which stores the home ID). Login / RefreshToken validate that
	// the workspace still exists and the user still has an active membership
	// (or CanAccessAllTenants) before honouring this preference; an
	// invalid pointer is best-effort cleared and the user falls back to
	// home. Refresh JWT claims have no tenant_id, so RefreshToken
	// re-resolves from this field.
	//
	// nil  = no preference (use user.TenantID, i.e. home)
	// *0   = "clear preference" sentinel for the partial-update endpoint
	//        (UpdateUserPreferences turns this into nil). Otherwise treat
	//        a stored *0 the same as nil.
	// *N   = preferred workspace id.
	LastActiveTenantID *uint64 `json:"last_active_tenant_id,omitempty"`

	// OidcOnlyLogin is set server-side when an account is auto-provisioned
	// via OIDC with a random password the user never received. The profile
	// UI hides self-service password rotation until the user sets a known
	// password via ChangePassword (which clears this flag).
	OidcOnlyLogin *bool `json:"oidc_only_login,omitempty"`

	// Gallery holds the user's image-gallery UI state: the search
	// activation mode and the per-attribute search-field toggles. Written
	// by the gallery's mode / checkbox interactions via the preferences
	// PUT; read back by GET /knowledge-bases/:id/gallery-config so the
	// gallery renders the same activation state on every device. Nil = the
	// user never touched the gallery controls (mode defaults to "all").
	Gallery *GalleryUserPrefs `json:"gallery,omitempty"`
}

UserPreferences holds per-user preferences persisted server-side so they sync across devices/browsers. Fields are pointers so we can distinguish "client didn't send this key" (leave existing value alone) from "client explicitly set false" — the partial-update merge in UpdateUserPreferences relies on this.

Adding a new preference key:

  1. Add a *T field below + JSON tag (snake_case, must match the front-end key).
  2. Extend the merge logic in service.UserService.UpdateUserPreferences.
  3. Surface the new knob in the frontend settings store.

No DB DDL is required — preferences is a single jsonb column.

func (UserPreferences) EffectiveBrowserSearchInstructions 

func (p UserPreferences) EffectiveBrowserSearchInstructions() string

EffectiveBrowserSearchInstructions returns the saved preference, or the default.

func (*UserPreferences) Scan 

func (p *UserPreferences) Scan(value interface{}) error

Scan implements sql.Scanner so GORM can hydrate UserPreferences back from the underlying column. Accept []byte (Postgres jsonb / SQLite blob) and string (some drivers hand TEXT as string) for portability.

func (UserPreferences) Value 

func (p UserPreferences) Value() (driver.Value, error)

Value implements driver.Valuer so GORM persists UserPreferences as JSON text (Postgres jsonb column / SQLite TEXT). Empty struct serialises to "{}", matching the NOT NULL DEFAULT '{}' column constraint.

type UserResourceFavorite 

type UserResourceFavorite struct {
	UserID       string    `json:"user_id"       gorm:"type:varchar(36);primaryKey"`
	TenantID     uint64    `json:"tenant_id"     gorm:"primaryKey"`
	ResourceType string    `json:"resource_type" gorm:"type:varchar(16);primaryKey"`
	ResourceID   string    `json:"resource_id"   gorm:"type:varchar(64);primaryKey"`
	CreatedAt    time.Time `json:"created_at"    gorm:"autoCreateTime"`
}

UserResourceFavorite is a per-(user, tenant) star on a single resource. See migration 000047 for the schema rationale (composite key, no FK, tenant-scoped on purpose).

func (UserResourceFavorite) TableName 

func (UserResourceFavorite) TableName() string

TableName pins the table to the migration's exact name so GORM's pluraliser doesn't drift if we ever rename the struct.

type VLMConfig 

type VLMConfig struct {
	// Enabled turns image captions on. Also send vlm_model_id.
	Enabled bool `yaml:"enabled" json:"enabled" extensions:"x-agent=vlm_enabled"`
	// Model that writes image captions. model.list returns the ids.
	ModelID string `yaml:"model_id" json:"model_id" extensions:"x-agent=vlm_model_id"`
	// DescriptionLanguage is the language of generated image captions. Empty follows the document language.
	DescriptionLanguage string `yaml:"description_language,omitempty" json:"description_language,omitempty" extensions:"x-agent=vlm_language"`

	// Interface Type: "ollama" or "openai"
	InterfaceType string `yaml:"interface_type" json:"interface_type"`
}

VLMConfig represents the VLM configuration

func (VLMConfig) IsEnabled 

func (c VLMConfig) IsEnabled() bool

IsEnabled 判断多模态是否启用（兼容新老版本） 新版本：Enabled && ModelID != "" 老版本：ModelName != "" && BaseURL != ""

func (*VLMConfig) Scan

Scan implements the sql.Scanner interface, used to convert database value to VLMConfig

func (VLMConfig) Value 

func (c VLMConfig) Value() (driver.Value, error)

Value implements the driver.Valuer interface, used to convert VLMConfig to database value

type VectorStore

	// Unique identifier (UUID, auto-generated)
	ID string `yaml:"id" json:"id" gorm:"type:varchar(36);primaryKey"`
	// Workspace ID for scoping
	TenantID uint64 `yaml:"tenant_id" json:"tenant_id"`
	// User-friendly name, e.g., "elasticsearch-hot"
	Name string `yaml:"name" json:"name" gorm:"type:varchar(255);not null"`
	// Engine type: postgres, elasticsearch, qdrant, milvus, weaviate, sqlite
	EngineType RetrieverEngineType `yaml:"engine_type" json:"engine_type" gorm:"type:varchar(50);not null"`
	// Driver-specific connection parameters (sensitive fields encrypted with AES-GCM)
	ConnectionConfig ConnectionConfig `yaml:"connection_config" json:"connection_config" gorm:"type:json"`
	// Optional index/collection configuration (engine-specific defaults if empty)

}

VectorStore represents a configured vector database instance for a workspace. Each workspace can register multiple VectorStore entries (even of the same engine type) to support multi-store scenarios (e.g., ES-hot + ES-warm clusters).

func BuildEnvVectorStores 

func BuildEnvVectorStores(retrieveDriver string, envLookup EnvLookupFunc) []VectorStore

BuildEnvVectorStores builds virtual VectorStore entries from RETRIEVE_DRIVER. Returns []VectorStore (not VectorStoreResponse) so that business logic (e.g., duplicate checking) can use them directly. API responses should wrap them via NewVectorStoreResponse.

Pure function — does not call os.Getenv directly.

Usage: 

types.BuildEnvVectorStores(os.Getenv("RETRIEVE_DRIVER"), os.Getenv)

func FindEnvVectorStore 

func FindEnvVectorStore(retrieveDriver string, envLookup EnvLookupFunc, id string) *VectorStore

FindEnvVectorStore finds a specific env store by its virtual ID.

	Sensitive   bool   `json:"sensitive,omitempty"`
	Default     any    `json:"default,omitempty"`
	Description string `json:"description,omitempty"`

	// Immutable marks a field whose value cannot be changed after the
	// VectorStore is first created. The UI shows the input as read-only
	// in edit mode; the backend rejects modification attempts. Used by
	// engines whose underlying index structure is fixed at create time
	// (e.g. OpenSearch's HNSW engine / M / ef_construction).
	Immutable bool `json:"immutable,omitempty"`

	// Min / Max set inclusive bounds for "number"-typed fields. nil
	// means no bound on that side. Frontend uses these to constrain
	// inputs; backend re-validates as defense-in-depth.
	Min *float64 `json:"min,omitempty"`
	Max *float64 `json:"max,omitempty"`

	// Enum constrains the allowed string values. Empty means no
	// constraint. Used by fields whose value space is closed (e.g.
	// OpenSearch's knn_engine ∈ {"lucene", "faiss"}).
	Enum []string `json:"enum,omitempty"`
}

VectorStoreFieldInfo describes a single configuration field exposed by /api/v1/vector-stores/types for the registration UI. The optional validation hints (`Immutable`, `Min`, `Max`, `Enum`) are used by both the frontend (to disable / constrain inputs) and the backend (defense-in-depth validation in the service layer).

type VectorStoreResponse

	// MountPath is the sandbox-internal path where the volume is mounted.
	// Default: /weknora/tenant/skills (customizable per use case).
	MountPath string `json:"mount_path,omitempty"`

	// Provider identifies the volume backend. Currently "e2b" or "cube".
	Provider string `json:"provider,omitempty"`

	// VolumeID is the provider-specific volume identifier, populated after
	// EnsureVolume / CreateVolume succeeds.
	VolumeID string `json:"volume_id,omitempty"`

	// VolumeName is the human-readable volume name, e.g.
	// "weknora-tenant-<id>-skills".
	VolumeName string `json:"volume_name,omitempty"`

	// VolumeOwnerFingerprint = sha256(provider + APIKey + APIURL).

	// API key, at which point the volume is no longer reachable and must
	// be recreated.
	VolumeOwnerFingerprint string `json:"volume_owner_fingerprint,omitempty"`
}

VolumeMountConfig configures a shared volume mount into every sandbox created for this tenant. Currently implemented for E2B volumes (used to share tenant-installed skills across sandbox sessions), but the schema is intentionally skill-agnostic so it can serve other volume-based use cases in the future.

	// IngestMaxInflight caps how many ingest batches for THIS KB may run
	// concurrently in the shared wiki worker pool (standard/Redis mode

	// Set it >= the wiki pool size to effectively disable the cap.
	IngestMaxInflight int `yaml:"ingest_max_inflight" json:"ingest_max_inflight,omitempty"`
}

WikiConfig stores wiki-specific configuration for a knowledge base. Applicable to document-type knowledge bases with wiki feature enabled. Whether the wiki feature is turned on is controlled by IndexingStrategy.WikiEnabled; this struct only carries wiki-specific tunables.

type WikiExtractionGranularity 

type WikiExtractionGranularity string

WikiExtractionGranularity controls how aggressive Pass 0 (candidate slug extraction) is. Higher granularity = more slugs, lower = tighter focus on the document's main subjects. 

const (
	// WikiExtractionFocused keeps only the document's main subjects (e.g.
	// a resume yields the person + their projects, nothing else). Most
	// aggressive slug pruning; avoids index bloat from incidental technology
	// names and generic concepts.
	WikiExtractionFocused WikiExtractionGranularity = "focused"

	// WikiExtractionStandard is the default: main subjects plus entities /
	// concepts that are substantively discussed (a dedicated paragraph or
	// multiple bullet points). Skips one-off mentions and commodity terms.
	WikiExtractionStandard WikiExtractionGranularity = "standard"

	// WikiExtractionExhaustive extracts every named entity and recognizable
	// concept, including stacks/libs mentioned in passing. Matches the
	// pre-granularity behavior. Useful when the KB is being used as a
	// glossary rather than a curated wiki.
	WikiExtractionExhaustive WikiExtractionGranularity = "exhaustive"
)

func (WikiExtractionGranularity) IsValid

	DeletedAt       gorm.DeletedAt `json:"deleted_at" gorm:"index"`
}

WikiFolder is a first-class directory node in the wiki browser. Folders exist independently of pages — an empty folder persists so users can lay out a skeleton and file pages into it later. The tree is an adjacency list (ParentID, "" = root); Path is the materialized "/"-joined name chain kept purely for cheap display/sort. A wiki page's placement is WikiPage.FolderID.

func (WikiFolder) TableName 

func (WikiFolder) TableName() string

TableName specifies the database table name

type WikiFolderCreateRequest

type WikiFolderNode struct {
	WikiFolder
	PageCount   int64 `json:"page_count" extensions:"x-agent"`
	HasChildren bool  `json:"has_children" extensions:"x-agent"`
}

WikiFolderNode is one directory node returned to the browser, enriched with the live page count directly under it and whether it has child folders so the UI can render an expand affordance without a second round-trip.

type WikiFolderUpdateRequest 

type WikiFolderUpdateRequest struct {
	Name       string `json:"name,omitempty"`
	ParentID   string `json:"parent_id,omitempty"`
	MoveParent bool   `json:"move_parent,omitempty"`
}

WikiFolderUpdateRequest renames and/or reparents a folder. ParentID is applied only when MoveParent is true so a pure rename doesn't have to re-send the (possibly root "") parent and risk an accidental move.

type WikiGraphData 

type WikiGraphData struct {
	Nodes []WikiGraphNode `json:"nodes"`
	Edges []WikiGraphEdge `json:"edges"`
	Meta  WikiGraphMeta   `json:"meta"`
}

WikiGraphData represents the link graph structure for visualization.

type WikiGraphEdge 

type WikiGraphEdge struct {
	Source string `json:"source"` // source slug
	Target string `json:"target"` // target slug
}

WikiGraphEdge represents a directed edge in the wiki link graph

type WikiGraphMeta 

type WikiGraphMeta struct {
	Mode      string `json:"mode"`
	Total     int    `json:"total"`            // total node count in the KB before filtering/limit
	Returned  int    `json:"returned"`         // number of nodes actually returned
	Truncated bool   `json:"truncated"`        // true when Returned < Total (after filters)
	Center    string `json:"center,omitempty"` // populated in ego mode
	Depth     int    `json:"depth,omitempty"`  // populated in ego mode
	// FamiliarCount is how many returned nodes are lit up for this person.
	FamiliarCount int `json:"familiar_count,omitempty"`
}

WikiGraphMeta describes how the returned subgraph relates to the full knowledge base graph. The frontend uses `Truncated` to decide whether to surface a "showing X of Y" hint and to enable ego-expansion UI.

type WikiGraphNode 

type WikiGraphNode struct {
	Slug     string `json:"slug"`
	Title    string `json:"title"`
	PageType string `json:"page_type"`
	// Number of inbound + outbound links
	LinkCount int `json:"link_count"`
	// Familiar is true when this page was built from a document this person
	// keeps citing in answers. It is a personal overlay, not a property of
	// the page: two people looking at the same wiki see different highlights.
	Familiar bool `json:"familiar,omitempty"`
}

WikiGraphNode represents a node in the wiki link graph

type WikiGraphRequest 

type WikiGraphRequest struct {
	KnowledgeBaseID string
	Mode            string   // "overview" (default) | "ego"
	Center          string   // ego mode center slug (required when Mode == "ego")
	Depth           int      // ego mode BFS depth, >= 1
	Types           []string // optional page_type filter; empty = no filter
	Limit           int      // max nodes to return; <= 0 means uncapped
	// FamiliarKnowledgeIDs are documents this person keeps drawing answers
	// from. Pages whose source_refs intersect the set are marked Familiar so
	// the existing Wiki graph can light them up without cloning a second graph.
	FamiliarKnowledgeIDs []string
}

WikiGraphRequest is the service-layer input for graph queries. It is populated by the HTTP handler from query params and passed down to the service, which is responsible for enforcing mode-specific semantics.

Limit policy: a non-positive `Limit` means "no cap" and is reserved for internal callers (e.g. wiki lint) that need the full graph. The HTTP handler always clamps `Limit` into a safe range before calling the service so external traffic can never request an uncapped graph.

type WikiIndexEntry 

type WikiIndexEntry struct {
	Slug         string      `json:"slug"`
	Title        string      `json:"title"`
	Summary      string      `json:"summary"`
	ParentSlug   string      `json:"parent_slug,omitempty"`
	CategoryPath StringArray `json:"category_path,omitempty"`
	WikiPath     string      `json:"wiki_path,omitempty"`
	Depth        int         `json:"depth,omitempty"`
	SortOrder    int         `json:"sort_order,omitempty"`
}

WikiIndexEntry is a single row in the structured wiki index response. Only the columns needed to render a clickable directory entry are carried — the backend projects SELECT slug, title, summary so a 40k- page KB does not pay for TEXT content transport on every index open.

type WikiIndexGroup 

type WikiIndexGroup struct {
	Type       string           `json:"type"`
	Total      int64            `json:"total"`
	Items      []WikiIndexEntry `json:"items"`
	NextCursor string           `json:"next_cursor,omitempty"`
}

WikiIndexGroup bundles the entries for one page_type into a page-sized slice. `Total` is the full count across the KB for the type; `Items` holds the current paginated window starting at `NextOffset - len(Items)`. An empty NextCursor means the window is already at the end of the type.

type WikiIndexResponse 

type WikiIndexResponse struct {
	Intro   string           `json:"intro"`
	Version int              `json:"version"`
	Groups  []WikiIndexGroup `json:"groups"`
}

WikiIndexResponse is what GET /wiki/index returns. The heavy directory markdown that used to sit in wiki_pages.content is gone — only the LLM- generated intro survives there. Everything else is assembled on demand from the index repo's light-column projection, keeping index reads O(page_size) regardless of KB size.

type WikiPage 

type WikiPage struct {
	// Unique identifier (UUID)
	ID string `json:"id" gorm:"type:varchar(36);primaryKey"`
	// Workspace ID for multi-workspace isolation
	TenantID uint64 `json:"tenant_id" gorm:"index"`

	Summary string `json:"summary" gorm:"type:text" extensions:"x-agent"`
	// Alternate names, abbreviations, acronyms or translated names
	Aliases StringArray `json:"aliases" gorm:"type:json"`
	// ParentSlug optionally points at the wiki page that should act as this
	// page's semantic parent in the directory tree. The parent may be empty
	// when the page is grouped only by FolderID.
	ParentSlug string `json:"parent_slug,omitempty" gorm:"type:varchar(255);index"`
	// FolderID is the single source of truth for where this page sits in the
	// directory tree — a reference to wiki_folders.id ("" = wiki root). The
	// CategoryPath / WikiPath / Depth fields below are denormalized caches
	// recomputed from this folder's chain on every write so list/index/search
	// queries don't have to join wiki_folders.
	FolderID string `json:"folder_id,omitempty" gorm:"column:folder_id;type:varchar(36);index;default:''" extensions:"x-agent"`
	// CategoryPath is the directory breadcrumb that groups this page in the
	// wiki browser, e.g. ["AI", "LLM 应用", "RAG"]. Derived cache of the
	// folder chain identified by FolderID.
	CategoryPath StringArray `json:"category_path,omitempty" gorm:"type:json"`
	// WikiPath is a normalized, sortable path derived from page_type,
	// category_path, and title. It keeps large directory listings cheap to sort.
	WikiPath string `json:"wiki_path,omitempty" gorm:"type:varchar(1024);index"`
	// Depth is len(CategoryPath), cached for filtering / display.
	Depth int `json:"depth,omitempty" gorm:"default:0;index"`
	// SortOrder allows generated or manually edited pages to control sibling
	// ordering before falling back to title.
	SortOrder int `json:"sort_order,omitempty" gorm:"default:0;index"`
	// References to source knowledge IDs that contributed to this page.
	// Format matches the legacy "<knowledge_id>|<doc_title>" convention used
	// across the ingest pipeline, so retract / display code can split on `|`
	// to recover the title. Document-level granularity.
	SourceRefs StringArray `json:"source_refs" gorm:"type:json"`
	// ChunkRefs records the specific source-document chunks this page was
	// built from — one UUID per cited chunk. Populated during ingest from
	// the chunk-citation pass; refreshed wholesale whenever the page is
	// re-materialized. Empty for summary pages (they are document-level
	// synopses and don't carry chunk-level citations). Use this when you
	// need to surface the underlying evidence for a wiki page, or to
	// retract citations when a source document is deleted.
	ChunkRefs StringArray `json:"chunk_refs" gorm:"type:json"`
	// Slugs of pages that link TO this page (backlinks)
	InLinks StringArray `json:"in_links" gorm:"type:json"`
	// Slugs of pages this page links to (outbound links)
	OutLinks StringArray `json:"out_links" gorm:"type:json"`
	// Arbitrary metadata (tags, categories, dates, etc.)
	PageMetadata JSON `json:"page_metadata" gorm:"column:page_metadata;type:json"`
	// Version number. Incremented only when a user-visible content field
	// (title, content, summary, page_type, status) actually changes; pure
	// bookkeeping writes (link maintenance, same-content re-ingest, status

	Version int `json:"version" gorm:"default:1" extensions:"x-agent"`

	LastEditSource string `json:"last_edit_source,omitempty" gorm:"type:varchar(16);default:''"`
	// LastEditorID is the user id of the caller that produced the current
	// version (empty for background pipeline writes).

	// Creation time
	CreatedAt time.Time `json:"created_at"`
	// Last update time

	DeletedAt gorm.DeletedAt `json:"deleted_at" gorm:"index"`
}

WikiPage represents a single wiki page in a wiki knowledge base. Wiki pages are LLM-generated, interlinked markdown documents that form a persistent, compounding knowledge artifact.

func (*WikiPage) BuiltFrom 

func (p *WikiPage) BuiltFrom(knowledgeIDs map[string]struct{}) bool

BuiltFrom reports whether any of this page's sources is in the given set.

func (*WikiPage) SourceKnowledgeIDs 

func (p *WikiPage) SourceKnowledgeIDs() []string

SourceKnowledgeIDs returns the document ids this page was built from.

func (WikiPage) TableName 

func (WikiPage) TableName() string

TableName specifies the database table name

type WikiPageDetail 

type WikiPageDetail struct {
	*WikiPage
	InLinkTitles map[string]string `json:"in_link_titles"`
}

WikiPageDetail adds display titles to the page detail response without persisting them or loading backlink content.

type WikiPageIssue 

type WikiPageIssue struct {
	ID                    string         `json:"id" gorm:"type:varchar(36);primaryKey" extensions:"x-agent=issue_id"`
	TenantID              uint64         `json:"tenant_id" gorm:"index"`
	KnowledgeBaseID       string         `json:"knowledge_base_id" gorm:"type:varchar(36);index"`
	Slug                  string         `json:"slug" gorm:"type:varchar(255);index" extensions:"x-agent"`
	IssueType             string         `json:"issue_type" gorm:"type:varchar(50)" extensions:"x-agent"`
	Description           string         `json:"description" gorm:"type:text" extensions:"x-agent"`
	SuspectedKnowledgeIDs StringArray    `json:"suspected_knowledge_ids" gorm:"type:json" extensions:"x-agent=knowledge_ids"`
	Status                string         `json:"status" gorm:"type:varchar(20);default:'pending';index" extensions:"x-agent"`
	ReportedBy            string         `json:"reported_by" gorm:"type:varchar(100)" extensions:"x-agent"`
	CreatedAt             time.Time      `json:"created_at" extensions:"x-agent"`
	UpdatedAt             time.Time      `json:"updated_at"`
	DeletedAt             gorm.DeletedAt `json:"deleted_at" gorm:"index"`
}

WikiPageIssue represents an issue flagged on a specific wiki page. These issues are typically identified by agents or linters and stored for review.

func (WikiPageIssue) TableName 

func (WikiPageIssue) TableName() string

TableName specifies the database table name

type WikiPageListRequest 

type WikiPageListRequest struct {
	KnowledgeBaseID string      `json:"knowledge_base_id"`
	PageType        string      `json:"page_type,omitempty"`      // filter by type
	Status          string      `json:"status,omitempty"`         // filter by status
	Query           string      `json:"query,omitempty"`          // full-text search
	FolderID        *string     `json:"folder_id,omitempty"`      // exact folder placement ("" = root)
	CategoryPath    StringArray `json:"category_path,omitempty"`  // exact directory path
	CategoryDepth   *int        `json:"category_depth,omitempty"` // exact directory depth, including 0 for root
	Page            int         `json:"page,omitempty"`           // pagination page (1-based)
	PageSize        int         `json:"page_size,omitempty"`      // pagination size
	SortBy          string      `json:"sort_by,omitempty"`        // "updated_at", "created_at", "title"
	SortOrder       string      `json:"sort_order,omitempty"`     // "asc" or "desc"
}

WikiPageListRequest represents a request to list wiki pages with filtering

type WikiPageListResponse 

type WikiPageListResponse struct {
	Pages      []*WikiPage `json:"pages"`
	Total      int64       `json:"total"`
	Page       int         `json:"page"`
	PageSize   int         `json:"page_size"`
	TotalPages int         `json:"total_pages"`
}

WikiPageListResponse represents a paginated list of wiki pages

type WikiPageLite 

type WikiPageLite struct {
	Slug     string      `json:"slug"`
	Title    string      `json:"title"`
	PageType string      `json:"page_type"`
	Status   string      `json:"status"`
	Aliases  StringArray `json:"aliases,omitempty"`
	OutLinks StringArray `json:"out_links,omitempty"`
}

WikiPageLite is a slim projection of WikiPage carrying only the fields the wiki ingest pipeline reaches for during Map / Reduce. It exists so per-batch fetcher queries don't have to load the full multi-MB content column for every page they want a title or out-link from.

Use cases:

  • SlugTitleFetcher: resolve slug -> title for cross-link injection.
  • cleanDeadLinks: read out_links + status without pulling content.
  • dedup pre-filter: title + aliases + page_type for the trgm / surface-similarity comparisons.

Aliases is included because dedup and cross-link injection both treat the alias surface forms as first-class match targets; OutLinks is included so dead-link cleanup can determine which pages reference a given dead slug without a second query.

type WikiPageMoveRequest 

type WikiPageMoveRequest struct {
	// Slug of the page to move.
	Slug string `json:"slug" binding:"required" extensions:"x-agent"`
	// Target folder id; empty means the top level.
	FolderID string `json:"folder_id" extensions:"x-agent"`
}

WikiPageMoveRequest relocates the page identified by Slug into FolderID ("" = root). Slug is carried in the body (not the path) because wiki slugs are hierarchical ("entity/acme") and would collide with gin's catch-all.

type WikiPageRevertRequest 

type WikiPageRevertRequest struct {
	// Slug of the page to revert.
	Slug string `json:"slug" binding:"required" extensions:"x-agent"`
	// Revision to restore. Versions start at 1.
	Version int `json:"version" binding:"required" minimum:"1" extensions:"x-agent"`
}

WikiPageRevertRequest rolls a page back to one of its stored revisions. Slug travels in the body (not the path) for the same reason as WikiPageMoveRequest: hierarchical slugs collide with gin's catch-all.

type WikiPageRevision 

type WikiPageRevision struct {
	ID              string      `json:"id" gorm:"type:varchar(36);primaryKey"`
	TenantID        uint64      `json:"tenant_id" gorm:"index"`
	KnowledgeBaseID string      `json:"knowledge_base_id" gorm:"type:varchar(36);index:idx_wiki_page_revisions_kb_slug"`
	PageID          string      `json:"page_id" gorm:"type:varchar(36);uniqueIndex:idx_wiki_page_revisions_page_version"`
	Slug            string      `json:"slug" gorm:"type:varchar(255);index:idx_wiki_page_revisions_kb_slug"`
	Version         int         `json:"version" gorm:"uniqueIndex:idx_wiki_page_revisions_page_version" extensions:"x-agent"`
	Title           string      `json:"title" gorm:"type:varchar(512)" extensions:"x-agent"`
	PageType        string      `json:"page_type" gorm:"type:varchar(32)"`
	Status          string      `json:"status" gorm:"type:varchar(32)"`
	Content         string      `json:"content,omitempty" gorm:"type:text" extensions:"x-agent,x-agent-max-runes=8000"`
	Summary         string      `json:"summary" gorm:"type:text" extensions:"x-agent"`
	Aliases         StringArray `json:"aliases" gorm:"type:json"`
	// Author of THIS version (same semantics as WikiPage.LastEditSource).
	EditSource string `json:"edit_source" gorm:"type:varchar(16);default:''" extensions:"x-agent"`
	EditorID   string `json:"editor_id" gorm:"type:varchar(64);default:''"`
	// When this version was authored (the page's updated_at while current).
	EditedAt  time.Time `json:"edited_at" extensions:"x-agent"`
	CreatedAt time.Time `json:"created_at"`
}

WikiPageRevision is one immutable snapshot of a superseded page version. The current version lives only in wiki_pages; when an edit replaces version V the pre-edit state is inserted here as (page_id, V) inside the same transaction, so every historical version stays diffable and revertable. Rows are pruned per WikiRevisionPruneRequest to bound storage on hot pipeline pages.

func (WikiPageRevision) TableName 

func (WikiPageRevision) TableName() string

TableName specifies the database table name

type WikiPageRevisionListResponse 

type WikiPageRevisionListResponse struct {
	Revisions      []*WikiPageRevision `json:"revisions"`
	Total          int64               `json:"total" extensions:"x-agent"`
	CurrentVersion int                 `json:"current_version" extensions:"x-agent"`
}

WikiPageRevisionListResponse is the payload for GET /wiki/revisions/*slug. Revisions hold the superseded versions (content omitted in list mode); the current version is described by CurrentVersion + the page row itself, which the frontend already has.

type WikiPageUpdateRequest 

type WikiPageUpdateRequest struct {
	Title    *string      `json:"title,omitempty"`
	Content  *string      `json:"content,omitempty"`
	Summary  *string      `json:"summary,omitempty"`
	PageType *string      `json:"page_type,omitempty"`
	Status   *string      `json:"status,omitempty"`
	Aliases  *StringArray `json:"aliases,omitempty"`
	// Version is the optimistic-lock guard: when > 0 the update is rejected
	// with a conflict if the stored version differs (someone else edited the
	// page since the client loaded it). 0 skips the check (legacy clients).
	Version int `json:"version,omitempty"`
}

WikiPageUpdateRequest is the partial-update payload for PUT /wiki/pages/*slug. All content fields are optional pointers — absent fields keep their stored value, so a client can change just the body without re-sending (and risking clobbering) title/status/aliases.

type WikiRevisionPruneRequest 

type WikiRevisionPruneRequest struct {
	PageID string
	// KeepFromVersion: snapshots below this version are dropped, but only
	// when their edit source is listed in PrunableSources.
	KeepFromVersion int
	PrunableSources []string
	// HardKeepFromVersion: snapshots below this version are always dropped,
	// whatever their author.
	HardKeepFromVersion int
}

WikiRevisionPruneRequest describes the two-tier retention applied to one page's snapshot history. A version threshold <= 0 disables that tier.

type WikiStats 

type WikiStats struct {
	TotalPages    int64            `json:"total_pages" extensions:"x-agent"`
	PagesByType   map[string]int64 `json:"pages_by_type"`
	TotalLinks    int64            `json:"total_links" extensions:"x-agent"`
	OrphanCount   int64            `json:"orphan_count" extensions:"x-agent"`   // pages with no inbound links
	RecentUpdates []*WikiPage      `json:"recent_updates"`                      // last N updated pages
	PendingTasks  int64            `json:"pending_tasks" extensions:"x-agent"`  // number of documents waiting to be ingested
	PendingIssues int64            `json:"pending_issues" extensions:"x-agent"` // number of pending wiki issues
	IsActive      bool             `json:"is_active" extensions:"x-agent"`      // whether wiki ingestion is currently running
}

WikiStats provides aggregate statistics about the wiki

type WorkerPoolConcurrency 

type WorkerPoolConcurrency struct {
	Core        int
	PostProcess int
	Enrichment  int
	Maintenance int
	Shared      int
	Wiki        int
}

WorkerPoolConcurrency contains the explicit per-instance pool capacities. Unlike the old ratio allocator, each field is independently configurable.

func DefaultWorkerPoolConcurrency 

func DefaultWorkerPoolConcurrency() WorkerPoolConcurrency

func ResolveWorkerPoolConcurrency 

func ResolveWorkerPoolConcurrency(read func(key, env string, fallback int) int) WorkerPoolConcurrency

ResolveWorkerPoolConcurrency centralizes setting keys, environment names, defaults, and invalid-value fallback for both server construction and the runtime API. The callback lets this package stay independent of the system setting service interface.

func (WorkerPoolConcurrency) UpstreamTotal 

func (c WorkerPoolConcurrency) UpstreamTotal() int

type WorkerServerStat 

type WorkerServerStat struct {
	Concurrency int
	Active      int
	Status      string
	Queues      map[string]int
}

WorkerServerStat is one live asynq server heartbeat. Queue weights identify which logical pool the server belongs to; the runtime handler aggregates these records across replicas so configured per-instance capacity is not confused with actual cluster capacity.
