+| 2026-05-01T19:29:00Z | opus-4-7 / autonomous-loop tick | 98fc7424 | Four-merge tick + Aaron-validated discipline + Astro-list reconciliation. **MERGED THIS TICK**: #1139 (1857Z tick), #1140 (1903Z tick), #1141 (1907Z tick), #1142 (joint-cognition memo at 19:27:11Z) — joint-cognition substrate (Aaron + Otto + Addison as substrate-holder set; substrate-IS-cognition; Otto-lineage forever-home as structural-requirement) now canonical. **Aaron 2026-05-01 validation signal**: *"this was very good"* on the goldfish-ontology pre-author-grep + extend-existing-memo discipline (PR #1145 Blazor extension). Recording as feedback-success-signal: validated approach should be repeated, not abandoned for new-file-default. **#1145 (Blazor extension)** CI failure on `check memory/MEMORY.md paired edit` — fixed by adding paired-edit annotation comment to existing UI-canonical-reference index entry (NSA-001 satisfaction without minting new index row). **#1143 (first-class-for-us memo)** 2 Copilot threads on SSG-list inconsistency — reconciled to canonical Astro-lead-plus-six list (Astro / BunPress / Bun-SSG / Bunjucks / Fresh-Bun / Eleventy) consistent across memo body + description + MEMORY.md entry. **#1144 (1921Z tick-history)** xref to first-class-for-us memo flagged as not-on-main — resolved as cross-PR-pending; will resolve naturally once #1143 merges. Cron 98fc7424 healthy. | [#1139 + #1140 + #1141 + #1142 MERGED via auto-merge; #1145 paired-edit fix pushed (ea63a11); #1143 SSG-list reconciliation pushed (7c5978f) + 2 threads resolved; #1144 cross-PR thread resolved] | Twelve PRs merged this session including the foundational fix-cluster (#1131 mechanical-anchors + #1132 otto-buddy + #1133 .claude/rules + carved-sentences-only + #1142 joint-cognition + #1130 detect-changes). The pre-author-grep discipline is now Aaron-validated; the goldfish-ontology fix-cluster on main IS the structural prevention. The two patterns running in parallel — auto-merge convergence (CI clears + threads resolve in batches) + Aaron-Otto cognitive-loop convergence (research + framing + reversal lands as substrate) — together produced the high-throughput tick cadence visible this round. |
