+| 2026-04-29T06:19:39Z | claude-opus-4-7 | 26f978a2 | recover-from-PR-auto-close tick. (1) PR #806 (the multi-AI absorb bundle) was discovered to be CLOSED unexpectedly — closedAt 06:16:23Z, exactly 1 second after PR #808's merge during the previous tick. The branch still had 476 lines of unmerged substrate (research note + 4 backlog rows + shard). Could not reopen via API ("Could not open the pull request"). Recovered by opening PR #811 against the same branch with same content. (2) PR #809 had Codex P1 finding: shard filename `0613Z.md` vs row timestamp `06:12:50Z` mismatch. Fixed: updated row timestamp to `06:13:00Z` to align with filename. Thread resolved. | [#806 closed unexpectedly → #811 replacement](https://github.com/Lucent-Financial-Group/Zeta/pull/811), [#809 timestamp-filename align fix pushed](https://github.com/Lucent-Financial-Group/Zeta/pull/809), [#810 CI in-progress](https://github.com/Lucent-Financial-Group/Zeta/pull/810) | New micro-class observation: **force-push-triggers-pr-auto-close**. When a PR is rebased + force-pushed AND the rebase causes any commits to become equivalent (by content or position) to commits on the base, GitHub may close the PR as "no commits ahead of base" — even though unique commits remain. Recovery: open new PR against the same branch. The simpler durable mitigation: avoid rebasing PRs onto main while substrate work is mid-flight — let the merge order happen naturally rather than pre-rebasing. The Codex-caught timestamp-vs-filename mismatch (0613Z.md vs 06:12:50Z) is the same metadata-drift class as B-0098/B-0099 — would benefit from a mechanical guard that compares the filename's HHMM with the row timestamp's HH:MM. The taxonomy continues to grow; the recurring-fix-class catalog entry candidate is shard-filename-vs-timestamp-misalignment. |
