     Status note:
   - shared contract now supports a canonical `trail-report` payload while reusing generic `artifact.created`, `artifact.linked`, and `memory.entry.created`
   - ActionTrail imports Cowork audit-export JSON into a persisted `trail-report` artifact plus latest created-event index
   - NoteLett imports the latest `trail-report` into a markdown audit note and preserves upstream trail-report causation
   - MindLyst imports the latest audit note into an `insight` memory proposal and preserves upstream note-link lineage
   - Codex completed a manual runtime walkthrough on `2026-04-03` using `/tmp/bytelyst-phase3-walkthrough.myuu1z`, which produced the causal chain `evt_trail_created_b40197d5302e -> evt_note_created_abc1ad821974 -> evt_note_linked_9fd9a2b03363 -> evt_memory_8103b59fb40c`
+  - review follow-up fixed the ActionTrail trace semantics so `causationId` and `parentEventId` no longer misuse Cowork task IDs
+  - NoteLett now exposes `/api/ecosystem/phase3/import-latest-trail-report`
+  - MindLyst now exposes the audited import path through `POST /api/memory` with `importLatestAuditNote: true`
