+| 2026-04-29T06:25:25Z | claude-opus-4-7 | 26f978a2 | auto-merge-arm tick. PR #811 (multi-AI absorb bundle reopened from #806) reached CLEAN status (20 success, 0 in-progress, 0 failed). Direct squash-merge rejected with "base branch policy prohibits the merge" — branch behind main (since #809 + #810 merged this session arc). Per the force-push-triggers-pr-auto-close lesson from previous tick, did NOT rebase manually. Instead armed auto-merge via `gh pr merge --auto` — queues the merge to fire once branch protection is satisfied (GitHub typically auto-updates the branch when auto-merge is armed and base branch advances). | [#811 auto-merge armed](https://github.com/Lucent-Financial-Group/Zeta/pull/811), [#812 CI nearly green](https://github.com/Lucent-Financial-Group/Zeta/pull/812), [#813 CI in-progress](https://github.com/Lucent-Financial-Group/Zeta/pull/813) | The force-push-vs-auto-merge choice point is now codified by experience: when a PR is CLEAN but BLOCKED-by-branch-up-to-date-policy, auto-merge is the safe path (no force-push, no auto-close risk). Direct rebase + force-push triggered the auto-close in the prior tick. The session arc has now produced multiple instances of the same shape: detect a problem → file the rule → next tick provides the test case → rule either holds or gets revised. The B-0101 reviewer-artifact taxonomy validated 3x; the force-push-triggers-pr-auto-close rule validated 1x (this tick); the durable-retry rule validated by virtue of being on main + future builds inheriting it. Strong behavioral evidence of scaffolded self-correction continues. |
