Note: repo memory had a ~7-week gap (last prior entry 2026-08-26); only 2026-10-16 to 2026-10-18 were backfilled per cold-start policy, full gap not reconstructed.

Trend: 📉📈 Success rate dipped to 57.1% on 10-17, then recovered to 76.9% on 10-18 (+19.8pp, significant). Avg duration fell sharply from 476.5min to 208.5min (-56%). Volume rose from 7 to 13 PRs (+86%).

Notable PRs

• #69988 — closed without merge (AI-credit guardrail rejection on Daily Code Metrics)
• #69940 — closed without merge (CI schema-version test fixture)
• #69997 — still open at collection time (~21h, below the 24h notability threshold)

Key Insights

• Both non-merged closures were CI/guardrail-driven (schema fixture, credit guardrail), not scope rejections; related fixes landed same day (Replace Linter Miner’s unavailable model #69990 swapped the unavailable model, Gate custom safe-output jobs on threat detection success #69995/Reject placeholder issue titles before consuming create_issue quota #69994 hardened the guardrails themselves)
• Avg duration (208.5min) is skewed by one outlier (Preserve AWF ranked choices and request/failure metadata in unified sessions #69848, 944min / ~15.7h); the other 9 merged PRs averaged ~126min
