- System overview: mark Phase 4 in-progress (M0 RU gate shipped), add
fleet_queue_state container + GET /fleet/queue-state, document the heartbeat
cadence vs 90s stale gotcha, the tracker-web caps=build form bug, the missing
deregister API, and the ended=-race fix; drop the now-false "roadmap §0 stale"
and "boxes 384/386 unticked" claims (both reconciled); link the redesign doc.
- Roadmap: §0 Phase 4 -> in progress (M0); align the Phase-2 §8 spec endpoint
sketches to the as-built API (/fleet/factories/enroll, /factories/heartbeat,
/fleet/claim) + note the heartbeat cadence and the M0 gate.
