Phase 3. Events are the append-only record of everything a mind does (ADR-0002). pkg/events defines the closed type vocabulary, categories, evidence references and the observation payload with explicit trust levels. The store validates and appends inside the caller's transaction, publishes to a bounded fan-out bus only after commit, queries by seq cursor with type/category/source/salience/confidence/time/search filters, and walks provenance: cause, parents, children, cited evidence, derived events and correlation groups. Durable per-consumer cursors never move backwards. Server-Sent Events streams (per mind and global) subscribe before replaying history after Last-Event-ID so nothing is missed, apply the same filter vocabulary live, and heartbeat. Operators can inject observations tagged with operator trust for demos and tests. UI: live thought stream with filters and paging, forensic event page with causal chain and evidence navigation, dashboard important events. Personality and status changes now leave operator_action events in the mind's own history. CLI: event inspect/list/tail, observe.
