[lifecycle-P2] Durable operation and crash recovery #1690
Description
Tracking
- Umbrella: #1688
- Source PR: #1626
- Task lifecycle gap report
- Task lifecycle remediation blocks
Scope
Own these gaps:
- LIFE-GAP-004
- LIFE-GAP-005
- LIFE-GAP-006
- LIFE-GAP-021
- LIFE-GAP-023
Own these blocks:
- LIFE-BLK-P2-004
- LIFE-BLK-P2-005
- LIFE-BLK-P2-006
- LIFE-BLK-P2-021
- LIFE-BLK-P2-023
Ownership boundary
Own durable operation intent, replay, and recovery. Cover pair writes, delegation, completion messages, shutdown, and deletion.
Dependencies
P2 follows P7 on the critical path and builds on P1 ownership. P2-006 also depends on P1 generation.
P5 durable child initialization depends on P2 delegation recovery. P6 completion contracts depend on P2 completion recovery.
Provenance
- #1540 records partial pair-write recovery needs.
- #1624 records restart-stable dead delegation chains.
These issues provide history only. Do not close or modify them through this workstream issue.

Hardened audit mapping
Add these owned mappings:
Strengthen LIFE-GAP-006 / LIFE-BLK-P2-006 with one failure-phase table. The table must cover completion-message persistence, both lifecycle files, child pending-action state, and resumed replay.
Cross-link: #1714 is the concrete rejected-delegation regression. The current branch directly models successful rejected-action settlement. Crash-safe settlement remains open under LIFE-GAP-039. Startup repair behavior remains open under LIFE-GAP-040.
