+| 2026-04-29T05:35:50Z | claude-opus-4-7 | 26f978a2 | recovery tick — ordinal-drift cascade self-correction. Two PRs merged this tick (#792 + #794, both already CLEAN). Then caught and reverted my own bad fix from PR #791: I had changed 0526Z to "twenty-first" per a Copilot P0 thread that didn't account for 0524Z already being "twenty-first" — my "fix" introduced a duplicate ordinal. Re-verified the day's actual sequence by reading every shard's claimed ordinal directly: 0521Z=nineteenth, 0522Z=twentieth, 0524Z=twenty-first, 0526Z=twenty-second (original was correct), 0527Z=twenty-third. Reverted 0526Z to "twenty-second". Also caught Copilot P1 on PR #793: PR-count assertion drifted across shards (0524 said 27, 0528 said 31, but only 1 PR merged between — historical count drift). Softened the claim to "continues across the session arc; per-shard counts have drifted historically and should be treated as approximate." | [#792 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/792), [#794 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/794), [#791](https://github.com/Lucent-Financial-Group/Zeta/pull/791) [#793](https://github.com/Lucent-Financial-Group/Zeta/pull/793) [#795](https://github.com/Lucent-Financial-Group/Zeta/pull/795) | Trajectory observation: the agent-overcorrection-thread class now has a worked example. The PR #791 "fix" was based on an incomplete read (the reviewer's comment cited two earlier shards, I trusted the citation, didn't read the intermediate ones). The lesson: when a reviewer flags ordinal off-by-one, read ALL recent shards to verify the actual sequence — not just the cited ones. Self-correction lesson preserved. The recurring-fix-class catalog continues to bound work with this newest entry: **trust-the-cited-context-without-verification** (a sub-class of agent-overcorrection-thread). The mechanical guard: a tick-ordinal-continuity lint (filed earlier as backlog) plus a discipline of re-reading the actual file sequence before "fixing" any ordinal claim. |
