# ActionTrail Ecosystem Adoption > **Repo:** `learning_ai_trails` > **Ecosystem focus:** Cowork audit -> trail-report artifact golden flow > **Status:** Phase 3 baseline implemented --- ## 1. Role In The Ecosystem ActionTrail is the canonical audit-normalization layer for Phase 3. It should: - accept structured Cowork audit exports - convert them into durable ecosystem `trail-report` artifacts - preserve causation and correlation for downstream consumers - make the audit flow readable without requiring Cowork runtime knowledge in every consumer --- ## 2. Current Adoption - `backend/src/lib/ecosystem-phase3.ts` creates and persists a canonical `trail-report` - latest indexes now include: - `latest-trail-report.json` - `latest-trail-report-created-event.json` - the Phase 3 payload captures: - action counts - tool call counts - approval counts - failure counts - safety signal counts - task list - action breakdown - normalized entry list --- ## 3. Remaining Follow-Up - add optional route/service wiring for importing Cowork exports through the live backend - map ActionTrail-native actions and approvals into the same artifact view - connect `audit.action.logged` taxonomy work when runtime event forwarding is added --- ## 4. Commits - `e294cf5`
