-Open coordination track with activity-core:
-
-1. Implement `discover_kaizen_scheduled_repos` per supplier spec (if not done)
-2. `make sync-activity-definitions` with coulomb-loop copies
-3. Dry-run resolver against pilot roster
-4. Enable one definition at a time (`hourly-metrics-optimize` first)
+2026-06-18: `activity_core/context_resolvers/kaizen.py` shipped (7 tests pass).
+Dry-run returned 6 scheduled runs. `ACTIVITY_DEFINITION_DIRS` includes coulomb-loop;
+DB sync pending when `ACTCORE_DB_URL` stack is up. Enable definitions incrementally.
