Notable PRs

Closed without merge (14) — largely superseded duplicates / abandoned WIP, not hard failures:

• Harden safe-output file protection against patch parser/apply drift #36725 / [WIP] Fix safe-outputs file-protection bypass issue #36726 — competing attempts at same safe-output file-protection hardening
• [WIP] Extract embedded issue template to shared partial #36743 / [WIP] Extract embedded issue template to shared partial for daily optimizer #36763 — duplicate [WIP] "extract embedded issue template" attempts
• Restore Copilot SDK driver custom-provider bootstrap #36728 — superseded by merged fix: resolve Copilot SDK custom provider in standalone driver main() #36769 (same Copilot SDK custom-provider fix)
• Fix daily-agent-of-the-day-blog-writer producing no safe outputs #36790, daily-ambient-context-optimizer: add gh-aw CLI preflight and noop fallback path #36792, Strengthen tools.cli-proxy builtin prompt with stdin printf invocation example #36807, Align ambient context in audit/logs to first-invocation input tokens #36851, Add max_turns_budget experiment to go-logger and support expression-safe Claude max-turns compilation #36853, Emit aggregated token-optimization performance tips when GitHub workflows are not using proxy mode #36917, Add confidence intent support to issue-mutating safe outputs #36924, Set built-in effective token defaults to 10M per run and 50M per day #36967 — reverted scope / superseded

Open (6) — all opened within last ~5h, none stale: #36900, #36936, #36937, #36952, #36964, #36965

Key Insights

• Dominant theme: token / ambient-context reduction — many merged PRs trimmed prompt surface, enabled gh-proxy/cli-proxy, and hardened safe-output fallback; correlates with the ~48% drop in avg merge time.
• WIP/duplicate churn persists — several closures are paired duplicate attempts (Harden safe-output file protection against patch parser/apply drift #36725/[WIP] Fix safe-outputs file-protection bypass issue #36726, [WIP] Extract embedded issue template to shared partial #36743/[WIP] Extract embedded issue template to shared partial for daily optimizer #36763); deduping concurrent agent attempts on one task would lift the headline success rate.
