Executive Summary

The 24-hour window from 2026-10-29 18:24 UTC through 2026-10-30 18:24 UTC is covered. The initial bulk continuation timed out, so I fetched its missing interval in bounded slices: 46 runs were collected for 18:27–20:40 UTC, and the 18:24–18:28 UTC boundary query returned zero runs.

AI Moderator remains the highest priority: 14 of 16 runs in the window reported ENOENT for /tmp/gh-aw/cache-memory/spam-log.json. The observed 14-day miss rate is 90.3% (65 of 72 cache-observed runs), with misses on six consecutive dates, October 25–30. known-issues.json already records #aw_aimod, so no duplicate was created. Five additional workflows had no cache-memory reads or writes in 3–5 runs over the last seven days despite high input usage; issues were created to add incremental state or disable unused cache-memory.

Findings

Severity	Workflow	Miss Streak	Miss Rate (14d)	Root Cause	Issue
🟠 High	AI Moderator	6 days	90.3% (65/72)	spam-log.json repeatedly absent	#aw_aimod (known issue reference; status unverified)
🟡 Medium	arXiv Paper Researcher: GitHub Agentic Workflows	No access in 4 runs	n/a	No cache reads/writes; 5.7M input tokens	#73280
🟡 Medium	Daily Storify	No access in 5 runs	n/a	No cache reads/writes; 1.29M input tokens	#73283
🟡 Medium	Daily Spending Forecast	No access in 4 runs	n/a	No cache reads/writes; 809K input tokens	#73282
🟡 Medium	Daily News	No access in 3 runs	n/a	No cache reads/writes; 652K input tokens	#73284
🟡 Medium	Workflow Normalizer	No access in 5 runs	n/a	No cache reads/writes; 452K input tokens	#73285

🔴 Critical Issues

No confirmed volatile run-ID cache key without restore-key fallback was found in the available run metadata.

🟠 High Priority

AI Moderator — Runs 40937916811, 40938510271, 40938519452, and 40938534497 on October 29, then repeated misses through run 41075217181 on October 30. Run 40938493026 read existing state once, but the next runs again reported ENOENT for spam-log.json. Verify that the file is written to the same stable path and persisted between runs, while keeping a safe empty-state fallback. The existing reference is #aw_aimod; its open/closed status could not be independently confirmed because the issue lookup was filtered by integrity controls.

🟡 Medium Priority

• arXiv Paper Researcher: GitHub Agentic Workflows — Four runs used 5,703,119 input tokens. Keep a stable index of papers already fetched and summarized, then process only new or changed papers. Issue: #73280.
• Daily Storify — Five runs used 1,289,798 input tokens. Persist covered sources and story topics so collection and synthesis can focus on new material. Issue: #73283.
• Daily Spending Forecast — Four runs used 808,927 input tokens. Reuse dated source snapshots and prior forecasts, and recalculate only when inputs change. Issue: #73282.
• Daily News — Three runs used 652,183 input tokens. Persist source coverage and completed items to filter duplicate collection. Issue: #73284.
• Workflow Normalizer — Five runs used 452,353 input tokens. Cache normalization results by stable source-file hash and revisit changed workflows only. Issue: #73285.

Daily Documentation Healer had one confirmed missing cache file on October 29, but its 14-day miss rate is 11.1% and it has no consecutive-day streak. Daily Safe Output Tool Optimizer is at 40%, below the issue threshold.
