Out-of-scope for autonomous fix without maintainer or CodeQL-expert input. **Skip-discipline cumulative**: #1106 (naming-consent rename + redaction) + #1112 (licensing/IP) + #1200 (CLAUDE.md cascade-rebase) + #1107/#1181/#1182/#1183 (substantive CI failures + 6+ unresolved-thread maintainer-gated content) + #659 (5 stale threads, ~6 days old, substantial review-thread reactivation needed) + #1194 (codeql 4.35.3 csharp regression) — all properly skipped. The autonomous loop's bounded-PR queue is **drained**; remaining open PRs are all genuine maintainer-gate. | Cumulative session count holds at **6 PRs merged via autonomous cron-loop** (#1097 + #1085 + #1431 + #1081 + #1083 + #1432); #1194 + #1197 + #1433 still wait-ci or have remaining real-failure work; ~7 PRs properly skipped per discipline. | This tick teaches **the dependabot triage subclass within bounded-fix discipline**: a dependabot PR with cancelled CI is bounded (rebase clears it); a dependabot PR with real test/scan failures is maintainer-gated when the new dependency version itself broke something the autonomous loop can't reasonably investigate (e.g., codeql-action version-bump regression on csharp scanner). The discriminator is "did the dependency-bump itself cause the failure, vs the dependency-bump merely re-ran stale CI?" Same as the stale-vs-real CI failure recognition class but specialized for dependabot. **Session-arc observation**: starting from cron-firing in maintainer-rest window, the queue progressed from "many bounded fixes available" → "diminishing bounded queue" → "drained-modulo-maintainer-gates". This natural arc IS the bounded-operational-PR-maintenance discipline working as designed — the loop converges on its own when the queue's bounded fraction is exhausted, leaving the maintainer's grading attention preserved for the genuinely substantial remaining PRs. |
