func WithConsumerClock(now func() time.Time) ConsumerOption

WithConsumerClock injects deterministic time.

func WithConsumerEventSink 

func WithConsumerEventSink(sink EventSink) ConsumerOption

WithConsumerEventSink records consumer telemetry.

func WithConsumerFailurePath 

func WithConsumerFailurePath(path string) ConsumerOption

WithConsumerFailurePath overrides the default <root>/_system/extractor/failures directory.

func WithConsumerInboxPath 

func WithConsumerInboxPath(path string) ConsumerOption

WithConsumerInboxPath overrides the default <root>/_inbox directory.

func WithConsumerLogger 

func WithConsumerLogger(logger *slog.Logger) ConsumerOption

WithConsumerLogger configures warning output.

type Event 

type Event struct {
	Op          string
	Turn        memcontract.TurnRecord
	SessionID   string
	WorkspaceID string
	AgentID     string

}

Event is redaction-safe extractor telemetry persisted into memory_events.

func (Event) Normalize 

func (e Event) Normalize(now func() time.Time) Event

Normalize returns a copy with canonical identity fields filled from the turn.

type EventSink 

type EventSink interface {
	RecordExtractorEvent(context.Context, Event) error
}

EventSink persists extractor telemetry.

type InboxConsumer 

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

InboxConsumer drains daemon-owned extractor inbox files through the write controller.

func NewInboxConsumer 

func NewInboxConsumer(root string, sink ProposalSink, opts ...ConsumerOption) (*InboxConsumer, error)

NewInboxConsumer constructs a FIFO inbox consumer.

func (*InboxConsumer) ConsumeOnce 

func (c *InboxConsumer) ConsumeOnce(ctx context.Context) (ConsumeResult, error)

ConsumeOnce processes all currently visible JSONL files in FIFO order.

type Option 

type Option func(*Runtime)

Option customizes the extractor runtime.

func WithClock 

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

WithClock injects deterministic time for tests.

func WithCoalesceMax 

func WithCoalesceMax(limit int) Option

WithCoalesceMax configures the hard queue merge limit.

func WithEventSink 

func WithEventSink(sink EventSink) Option

WithEventSink records extractor telemetry.

func WithInboxPath 

func WithInboxPath(path string) Option

WithInboxPath overrides the default <root>/_inbox directory.

func WithLogger 

func WithLogger(logger *slog.Logger) Option

WithLogger configures warning output.

type Producer 

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

Producer writes extractor candidates into the daemon-owned inbox.

func NewProducer 

func NewProducer(root string, now func() time.Time, opts ...ProducerOption) (*Producer, error)

NewProducer constructs an inbox producer rooted at the memory directory.

func (*Producer) Write 

func (p *Producer) Write(
	ctx context.Context,
	turn memcontract.TurnRecord,
	candidates []memcontract.Candidate,
) (string, int, error)

Write persists one JSONL inbox file for a completed extractor turn.

type ProducerOption 

type ProducerOption func(*Producer)

ProducerOption customizes inbox production.

func WithProducerInboxPath 

func WithProducerInboxPath(path string) ProducerOption

WithProducerInboxPath overrides the default <root>/_inbox directory.

type ProposalSink 

type ProposalSink interface {
	ProposeCandidate(context.Context, memcontract.Candidate) (memcontract.Decision, error)
}

ProposalSink is the controller-backed handoff used by the inbox consumer.

type Runtime 

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

Runtime owns asynchronous transcript extraction and daemon inbox production.

func NewRuntime 

func NewRuntime(
	ctx context.Context,
	root string,
	extractor memcontract.Extractor,
	opts ...Option,
) (*Runtime, error)

NewRuntime constructs a daemon-owned extractor runtime.

func (*Runtime) Close 

func (r *Runtime) Close(ctx context.Context) error

Close rejects new work, joins workers, and flushes the extractor.

func (*Runtime) Drain 

func (r *Runtime) Drain(ctx context.Context) error

Drain waits for the current queue to empty and asks the extractor to flush.

func (*Runtime) Enqueue 

func (r *Runtime) Enqueue(ctx context.Context, turn memcontract.TurnRecord) error

Enqueue requests extraction for one transcript turn using one in-flight plus one queued item per session.

func (*Runtime) HandleSessionMessagePersisted 

func (r *Runtime) HandleSessionMessagePersisted(
	ctx context.Context,
	payload hookspkg.SessionMessagePersistedPayload,
) error

HandleSessionMessagePersisted converts the durable-message hook into an extractor turn.

func (*Runtime) RecordToolWrite 

func (r *Runtime) RecordToolWrite(sessionID string, turnSeq int64)

RecordToolWrite marks an explicit root-agent memory tool write for turn-level mutual exclusion.

func (*Runtime) Stats 

func (r *Runtime) Stats() RuntimeStats

Stats returns current queue counters without blocking workers.

type RuntimeStats
