[edelauna]

Tracking

• Umbrella: #1688
• Source PR: #1626
• Task lifecycle gap report
• Task lifecycle remediation blocks

Scope

This program owns no baseline LIFE-GAP-* ID.

Own these optional blocks:

• FANOUT-BLK-001
• FANOUT-BLK-002
• FANOUT-BLK-003
• FANOUT-BLK-004

Ownership boundary

Own optional concurrent live-parent and sibling fan-out. Cover reservation, rollback, permit release, result routing, orphan cleanup, and task-scoped end-to-end behavior.

Dependencies

FANOUT-BLK-001 depends on P7 and P1 ownership. FANOUT-BLK-002 also depends on P2 recovery.

FANOUT-BLK-003 also depends on P4 identity. FANOUT-BLK-004 depends on FANOUT-BLK-001 through FANOUT-BLK-003.

Baseline exclusion

This program is explicitly excluded from baseline closure. It does not own LIFE-GAP-014 or any other baseline GAP.

Provenance

This issue is the successor tracker for #369 and #372.

Those issues provide history only. Do not close or modify them through this program issue.

Closure

Close this program only when all listed FANOUT block acceptance criteria pass. Its closure does not control baseline closure.
