+| 2026-04-29T04:32:31Z | claude-opus-4-7 | 26f978a2 | third merge wave — narrow tick. Two more PRs squash-merged onto main: PR #761 (.gitattributes artifact diff-suppression, synthesis-packet item 1/6 — lands `*.txt`/`*.log` diff suppression under `docs/lost-substrate/artifacts/**` while preserving review-readability of triage-report.md and other markdown summaries); PR #767 (merge-and-drain shard from prior tick). Substrate-drain wave is now 9 PRs merged this session arc since corruption-triage closure (#758/#760/#763/#765/#759/#762/#764/#761/#767). PR #766 + #768 remain open; both have 0 unresolved threads — just waiting for CI cycles to complete. Synthesis-packet item 1/6 (.gitattributes) is now on main; items 2-6 remain queued under task #309 per Amara's narrowing. No new conceptual substrate opened this tick. | [#761 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/761), [#767 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/767), [#766](https://github.com/Lucent-Financial-Group/Zeta/pull/766) [#768](https://github.com/Lucent-Financial-Group/Zeta/pull/768) | Trajectory observation: convergence holds. Each merge wave drops the queue by 2-3 PRs while opening 0 new threads. The remaining open PRs are waiting on CI completion, not on more fixes. The substrate-drain pattern Amara predicted ("the loop is becoming inspectable") is visible at the wave-cadence: each tick delivers a small wave instead of opening more work. Keeper preserved as load-bearing: "Do not let Claude/Otto open a bunch of new PRs for all these insights" (Amara 2026-04-29). |
