}

Interpreted brain signal extracted from a raw Event (ADR-032 §4).

interpret() is the single mapping layer from the shared event log to brain-internal signals. No parallel event enum is needed; the Event substrate IS the source of truth.

Variants

RecallHit

A recall verb succeeded — positive signal for the recalled entity.

Fields

target_id: Uuid

latency_us: i64

RecallMiss

A recall verb returned no results — miss signal for tuning.

SearchCompleted

A search verb completed.

Fields

latency_us: i64

Feedback

Explicit feedback on a specific entity, emitted by brain.feedback.

Fields

target_id: Uuid

signal: FeedbackSignal

served_by_profile_id: Option<String>

Profile that served the event being rated, if known.

section_signals: Option<HashMap<SectionType, FeedbackSignal>>

SemanticFeedback

Semantic feedback with event kind (issue #268).

Produced when the signal field in a brain.feedback event is one of the FeedbackEventKind names (explicit_positive, correction, etc.). The fold uses event_kind.update_weight() to scale the posterior update.

Fields

target_id: Uuid

event_kind: FeedbackEventKind

served_by_profile_id: Option<String>

NoteAccessed

Any other note-substrate access (get, list on notes).

Fields

target_id: Uuid

Irrelevant

Event is not relevant to the brain.

Trait Implementations
