Cache Strategy Analysis Report

Date: 2026-10-22
Runs Analyzed: 84 completed cache-memory runs (86 found; 2 still in progress)
Workflows with cache-memory: 70 distinct workflows in the available log set

---

Executive Summary

The available logs show 36 confirmed cache reads, 3 confirmed misses, and 45 runs without a decisive cache outcome. The three misses were all from AI Moderator: each returned ENOENT for /tmp/gh-aw/cache-memory/spam-log.json. Its historical streak is now 5 days, with a 97.3% miss rate across 37 observed records available from October 13 onward. The workflow uses a stable owner-based key with one-day retention; the evidence points to the state file not persisting between runs.

All five threshold findings below already have entries in known-issues.json; no duplicate issues were created. The Daily Go Test Parallelizer continues to show cache reads: 11 of its 12 runs in this window had explicit read evidence and none had a confirmed miss.

Coverage is incomplete. The requested continuation was fetched, but the summary still returns the same cursor (before run 39702039618, ending 2026-10-22 00:49:50Z). The summary reports 382 runs while 489 timestamp-filtered run metadata records are cached. Findings cover the available cache-memory logs only. Historical cache records begin on October 13, so 14-day rates use the available sample.

Findings

Severity	Workflow	Miss Streak	Miss Rate (14d)	Root Cause	Issue
🟠 High	AI Moderator	5 days	97.3% (36/37)	Repeated ENOENT reading spam-log.json; owner-based key is stable, but retention is 1 day.	Tracked: #aw_aimod
🟠 High	Daily Safe Output Tool Optimizer	1 day	100% (1/1 observed)	One historical missing-state read; the latest run had no decisive cache signal. Small sample.	Tracked: #aw_safeopt
🟠 High	Weekly Network Domain Set Audit	1 day	100% (1/1 observed)	One observed missing-state read and no successful hit recorded. Small sample.	Tracked: #aw_netcache
🟡 Medium	Daily Rendering Scripts Verifier	0 days	0% (0/3)	Cache writes are visible, but no successful prior-state read is recorded; no hit in the last 7 days.	Tracked; issue number unavailable
🟡 Medium	Smoke Copilot	0 days	n/a (0 observed)	No cache hit or miss is visible in 23 recent records; no hit in the last 7 days.	Tracked: #aw_smokecop

🔴 Critical Issues

None found.

🟠 High Priority

AI Moderator has the clearest repeated miss signal. The three current-window reads failed at /tmp/gh-aw/cache-memory/spam-log.json; the prior four-day streak advanced to five. The source declares spam-tracking-${{ github.repository_owner }} with one-day retention and allows the file to be absent. Ensure the workflow writes the updated log even when it finds no spam, and keep retention longer than the expected run interval.

Daily Safe Output Tool Optimizer and Weekly Network Domain Set Audit each have a 100% rate from one observed miss. Both have existing tracker entries; the small samples should be kept in view when prioritizing fixes.

🟡 Medium Priority

Daily Rendering Scripts Verifier wrote latest.json in the current window, but the captured history has no successful read signal. Read and compare the prior result before replacing it.

Smoke Copilot has no decisive cache outcome in the available session records. Confirm that the workflow reads prior state before repeating work and records a useful cache hit.

Healthy Workflows

These workflows show repeatable cache reads in the available records:

Workflow	Cache Hit Rate (14d)	Last Miss
Daily Go Test Parallelizer	95.5% of classifiable outcomes (42 hits / 44 outcomes); 3.2% miss rate across 62 observed runs	2026-10-19

In its current 24-hour sample, 11 of 12 runs had explicit cache-read evidence and none had a confirmed miss. Eighteen older observed records had no decisive hit or miss signal.

Issues Created Today

No new issues created — all threshold findings are already tracked. The cache contains the tracker references shown above; the real issue number for Daily Rendering Scripts Verifier was not returned in the stored record.
