Cache Strategy Analysis Report

Date: 2026-10-28
Runs Analyzed: 456 run bundles with aw_info.json in the available 24-hour collection
Workflows with cache-memory: 75

---

Executive Summary

The available logs contain 99 cache-memory runs across 75 workflows. Cache operations were observed in 68 runs, with 25 successful reads and 18 missing or empty cache signals; seven runs had both a successful read and a miss for different state. AI Moderator remains the main recurring problem: 51 misses in 56 observed runs over 14 days (91.1%), including 11 missing spam-log.json reads in this window. Its existing finding is tracked in cache memory as #aw_aimod.

Two new issues were created for no-hit cases: Daily AW Cross-Repo Compile Check has no successful cache read since 2026-10-20 while it repeats repository compile/fix work, and Cache directory setup (the Daily Security Red Team workflow) has no successful read in three cache-observed runs over the last 7 days while writing tracker and scan-history state. Daily Safe Output Tool Optimizer and Weekly Network Domain Set Audit also meet historical thresholds, but their findings are already tracked.

Coverage note: the supplemental AI Moderator log query stopped at the storage limit and returned only one run, already in the analyzed set. Runs §40611789380 and §40639035000 have run metadata but no aw_info.json bundle, so they are excluded from the cache metrics. The 24-hour analysis is incomplete for those entries. Prior issue references below use the values stored in known-issues.json; numeric issue IDs were not available for several older records.

Findings

Severity	Workflow	Miss Streak	Miss Rate (14d)	Root Cause	Issue
🟠 High	AI Moderator	4 days	91.1% (51/56 observed)	Repeated ENOENT reading spam-log.json	Tracked: #aw_aimod
🟠 High	Weekly Network Domain Set Audit	0 current days	100% (1/1 observed)	One missing cache read; no cache-observed run in the last 7 days	Tracked: #aw_netcache
🟡 Medium	Daily Safe Output Tool Optimizer	0 current days	50% (2/4 observed)	Repeated missing optimizer state; no hit in the last 7 days	Tracked: #aw_safeopt
🟡 Medium	Daily AW Cross-Repo Compile Check	0 explicit misses	0% explicit misses; no hit for 8 days	Timestamped results are written, but prior selection/history is not loaded before the recurring compile pass	New: #72743
🟡 Medium	Cache directory setup (Daily Security Red Team)	0 explicit misses	0% explicit misses; 0/3 hits in the last 7 days	Tracker and scan history are written, but no successful read was recorded; initialization can reset the technique index	New: #72744
🟡 Medium	Agent Job Health Monitor	0 explicit misses	0% explicit misses; no hit since 2026-10-21	Four cache-observed runs in the last 7 days had no successful read	Tracked: #aw_agenthlth
🟡 Medium	Daily Rendering Scripts Verifier	0 current days	14.3% (1/7 observed)	Cached rendering record was rejected and no later hit was recorded	Tracked; numeric issue ID unavailable

🟠 High Priority

• AI Moderator — 11 runs in this window returned ENOENT for /tmp/gh-aw/cache-memory/spam-log.json. The overall cache has some successful reads today, but this state file remains missing repeatedly. Recommended fix: persist the moderation history at the same path and confirm later runs read a non-empty file.
• Weekly Network Domain Set Audit — the 14-day rate is based on one observed cache run and is therefore low confidence. The prior missing-file finding is already tracked; review it when this workflow runs again.

🟡 Medium Priority

• Daily Safe Output Tool Optimizer — 2 of 4 observed runs missed state and there was no successful read in the last 7 days. The existing issue is already recorded.
• Daily AW Cross-Repo Compile Check — run §40658728562 recorded cache activity without a successful read. The workflow writes timestamped outputs and latest-selected.json; load that pointer and compare repository revisions before repeating compile/fix passes.
• Cache directory setup / Daily Security Red Team — run §40602446914 wrote technique-tracker.json, scan-history.json, and a timestamped scan, but no successful cache read was recorded. Confirm state restoration before initializing defaults so daily technique rotation persists.
• Agent Job Health Monitor and Daily Rendering Scripts Verifier — both already have tracked findings for the seven-day no-hit condition.

Healthy Workflows

These workflows had recent successful reads and no recorded misses in the 14-day window:

Workflow	Cache Hit Rate (14d)	Last Miss
Daily Go Function Namer	87.5% (7/8)	None recorded
CLI Version Checker	70% (7/10)	None recorded
Step Name Alignment	70% (7/10)	None recorded

Issues Created Today

• #72743 — Daily AW Cross-Repo Compile Check has not reused its cache in 8 days.
• #72744 — Cache directory setup has no successful cache read in three recent observed runs.

The analyzer also found threshold-level findings for AI Moderator, Daily Safe Output Tool Optimizer, Weekly Network Domain Set Audit, Agent Job Health Monitor, and Daily Rendering Scripts Verifier; these are already represented in known-issues.json.
