Overview

Package audit writes a bounded, local JSONL audit trail without retaining terminal input, raw prompt matches, environment values, or backend errors.

var ErrClosed = errors.New("enregistreur d'audit fermé")
View Source 
var ErrNotAuditJournal = errors.New("le chemin d'audit contient un fichier étranger")

ErrNotAuditJournal reports an audit path that already holds a file Relayer did not write.

Functions

func AuditGenerationIndex 

func AuditGenerationIndex(base, name string) (int, bool)

AuditGenerationIndex applies the exact filename recognition used by audit rotation. It is exported within Relayer's internal boundary so passive diagnostics can inspect precisely the files the runtime would mutate.

func DefaultPath 

func DefaultPath() (string, error)

DefaultPath returns the private per-user audit file location.

func Redact 

func Redact(value string) string

Redact removes common credential forms from arbitrary text. It is intentionally conservative and idempotent.

func ResolvePath 

func ResolvePath(path string) (string, error)

ResolvePath returns an absolute effective path, using DefaultPath for an empty configured value.

func Validate 

func Validate(config Config) error

Validate rejects ambiguous or unsafe recorder settings.

func VerifyJournalFile 

func VerifyJournalFile(path string) error

VerifyJournalFile reports whether an existing path holds a Relayer audit journal. It only reads, so read-only diagnostics can warn about a foreign file before startup refuses to open it. An absent path is not an error here: callers decide what a missing journal means.

Types

type Config 

type Config struct {
	Enabled       bool   `json:"enabled" yaml:"enabled"`
	Mode          Mode   `json:"mode" yaml:"mode"`
	Path          string `json:"path" yaml:"path"`
	MaxFileSizeMB int    `json:"max_file_size_mb" yaml:"max_file_size_mb"`
	MaxFiles      int    `json:"max_files" yaml:"max_files"`
}

Config controls local audit persistence. MaxFiles counts the active file as well as its rotated generations.

func DefaultConfig 

func DefaultConfig() Config

DefaultConfig enables a conservative metadata-only audit trail.

type Decision 

type Decision string

Decision is the audited policy outcome. It intentionally differs from an adapter's wire decision: asking a human is an explicit, content-free audit action rather than a copy of the submitted terminal input. 

const (
	DecisionAllow   Decision = "allow"
	DecisionAsk     Decision = "ask"
	DecisionDeny    Decision = "deny"
	DecisionUnknown Decision = "unknown"
)

type DecisionBy 

type DecisionBy string

DecisionBy identifies the actor without storing any submitted value. 

const (
	DecisionBySystem  DecisionBy = "system"
	DecisionByHuman   DecisionBy = "human"
	DecisionByPolicy  DecisionBy = "policy"
	DecisionByUnknown DecisionBy = "unknown"
)

type Entry 

type Entry struct {
	SchemaVersion int                `json:"schema_version"`
	Sequence      uint64             `json:"sequence"`
	Timestamp     time.Time          `json:"timestamp"`
	EntryID       string             `json:"entry_id"`
	RunID         string             `json:"run_id"`
	Kind          Kind               `json:"kind,omitempty"`
	SessionID     string             `json:"session_id,omitempty"`
	AgentID       string             `json:"agent_id,omitempty"`
	Backend       string             `json:"backend,omitempty"`
	Adapter       string             `json:"adapter,omitempty"`
	EventID       string             `json:"event_id,omitempty"`
	EventType     adapters.EventType `json:"event_type,omitempty"`
	Risk          adapters.RiskLevel `json:"risk,omitempty"`
	Rule          string             `json:"rule,omitempty"`
	Decision      Decision           `json:"decision,omitempty"`
	DecisionBy    DecisionBy         `json:"decision_by,omitempty"`
	Outcome       Outcome            `json:"outcome,omitempty"`
	Reason        string             `json:"reason,omitempty"`
	Summary       string             `json:"summary,omitempty"`
	Sensitive     bool               `json:"sensitive"`
	Metadata      map[string]string  `json:"metadata,omitempty"`
}

Entry is the versioned JSONL record. It intentionally has no Match, manual-input, environment, or raw-error field.

func SanitizeEntry 

func SanitizeEntry(entry Entry, mode Mode) Entry

SanitizeEntry returns a deep, redacted copy suitable for the selected mode.

type FileSink 

type FileSink struct {
	// contains filtered or unexported fields
}

FileSink writes complete lines synchronously and rotates them by size.

func NewFileSink 

func NewFileSink(path string, maxBytes int64, maxFiles int) (*FileSink, error)

NewFileSink opens a private append-only audit file. maxFiles includes the active file, so maxFiles=1 retains no rotated generation.

func (*FileSink) Close 

func (s *FileSink) Close() error

Close syncs and closes the active file once.

func (*FileSink) Path 

func (s *FileSink) Path() string

Path returns the absolute active file path.

func (*FileSink) WriteLine 

func (s *FileSink) WriteLine(line []byte) error

WriteLine appends and syncs exactly one complete JSONL line.

type Kind 

type Kind string

Kind identifies a closed set of audit lifecycle records. 

const (
	KindRunStarted     Kind = "run_started"
	KindRunFinished    Kind = "run_finished"
	KindSessionStarted Kind = "session_started"
	// KindSupervisionFinished means Relayer stopped supervising the session;
	// it does not claim that a persistent tmux process exited.
	KindSupervisionFinished Kind = "supervision_finished"
	KindSessionFinished     Kind = "session_finished"
	KindEventDetected       Kind = "event_detected"
	// KindEventWithdrawn records that an occurrence which was awaiting a human
	// stopped being pending without a decision being delivered. It is the only
	// evidence that a supervision gate opened on its own.
	KindEventWithdrawn  Kind = "event_withdrawn"
	KindPolicyEvaluated Kind = "policy_evaluated"
	KindDecision        Kind = "decision"
	KindDelivery        Kind = "delivery"
	// KindOperatorInput records only the lifecycle of a direct, human line
	// submission. Entry intentionally has no field for the submitted text,
	// its length, or the encoded terminal bytes.
	KindOperatorInput  Kind = "operator_input"
	KindAttachStarted  Kind = "attach_started"
	KindAttachFinished Kind = "attach_finished"
	KindBackendError   Kind = "backend_error"
	KindSessionCleanup Kind = "session_cleanup"
	KindUnknown        Kind = "unknown"
)

type LineSink 

type LineSink interface {
	WriteLine([]byte) error
	Close() error
}

LineSink owns persistence of complete JSONL lines.

type Mode 

type Mode string

Mode controls how much already-sanitized event information reaches disk. 

const (
	ModeOff      Mode = "off"
	ModeMetadata Mode = "metadata"
	ModeDetailed Mode = "detailed"
)

type Option 

type Option func(*openOptions) error

Option customizes Open without weakening its filesystem invariants.

func WithClock 

func WithClock(clock func() time.Time) Option

WithClock supplies a deterministic recorder clock.

func WithIDGenerator 

func WithIDGenerator(generator func() (string, error)) Option

WithIDGenerator supplies run and entry identifiers.

func WithRunID 

func WithRunID(runID string) Option

WithRunID binds audit records to an externally reserved runtime identity. This keeps GUI generation identity stable even when auditing is disabled.

type Outcome 

type Outcome string

Outcome is a safe, finite result vocabulary for lifecycle and policy audit. 

const (
	OutcomeStarted                   Outcome = "started"
	OutcomeFinished                  Outcome = "finished"
	OutcomeDetected                  Outcome = "detected"
	OutcomePending                   Outcome = "pending"
	OutcomeInFlight                  Outcome = "in_flight"
	OutcomeApplied                   Outcome = "applied"
	OutcomeAsk                       Outcome = "ask"
	OutcomeDryRun                    Outcome = "dry_run"
	OutcomeFallbackUnsupported       Outcome = "fallback_unsupported"
	OutcomeFallbackStale             Outcome = "fallback_stale"
	OutcomeFallbackDeliveryUncertain Outcome = "fallback_delivery_uncertain"
	OutcomeSucceeded                 Outcome = "succeeded"
	OutcomeFailed                    Outcome = "failed"
	OutcomeCancelled                 Outcome = "cancelled"
	OutcomeSkipped                   Outcome = "skipped"
	OutcomeUnknown                   Outcome = "unknown"
)

type Recorder 

type Recorder struct {
	// contains filtered or unexported fields
}

Recorder assigns identities and a total order before writing sanitized JSONL.

func NewRecorder 

func NewRecorder(
	config Config,
	sink LineSink,
	clock func() time.Time,
	idGenerator func() (string, error),
) (*Recorder, error)

NewRecorder constructs a recorder around an injectable line sink, clock, and ID generator. Nil clock and generator select secure production defaults.

func Open 

func Open(config Config, options ...Option) (*Recorder, error)

Open creates a rotating FileSink and wraps it in a Recorder. Disabled and off configurations perform no filesystem or ID-generator work.

func (*Recorder) Close 

func (r *Recorder) Close() error

Close is safe to call concurrently and closes the underlying sink once.

func (*Recorder) Enabled 

func (r *Recorder) Enabled() bool

Enabled reports whether this recorder performs any work.

func (*Recorder) Path 

func (r *Recorder) Path() string

Path returns the configured or effective audit path.

func (*Recorder) Record 

func (r *Recorder) Record(entry Entry) error

Record sanitizes and synchronously persists one entry. Holding the recorder lock through WriteLine makes Sequence identical to accepted on-disk order.

func (*Recorder) RunID 

func (r *Recorder) RunID() string

RunID returns the immutable identifier shared by this recorder's entries.
