Cache Strategy Analysis Report

Date: 2026-10-19
Runs Analyzed: 116 cache-memory-enabled runs
Workflows with cache-memory: 83

Executive Summary

The downloaded run records cover 2026-10-18 18:42 UTC through 2026-10-19 18:39 UTC. The workflow-log query returned no runs in the 18:40–18:42 UTC edge window. Of 116 cache-memory runs, 74 sessions showed explicit cache operations, 18 showed a missing-file signal, and 2 showed a successful cache-file read. The remaining 42 runs had no explicit cache operation evidence; skipped jobs and sessions without cache access are not counted as misses.

AI Moderator remains the clearest repeat issue: it had cache misses on two consecutive days and a 96.6% miss rate among 29 observed runs in the available 14-day history. Its issue is already recorded in the known-issues map. No new issue was warranted.

Findings

Severity	Workflow	Miss Streak	Miss Rate (14d)	Root Cause	Issue
🟠 High	AI Moderator	2 days	96.6% (28/29 observed)	spam-log.json reads returned ENOENT in 15 of 16 observed runs in this 24-hour window; for example, run 39231761529.	Already tracked

The 14-day rate is based on an incomplete sample: cache records are unavailable for 2026-10-14 and 2026-10-15. Review the existing AI Moderator issue and ensure the spam log is persisted at the path read by later runs.

Other cache signals monitored

• Daily Go Test Parallelizer: 2 misses in 10 observed runs in the last 24 hours (20%); the 14-day rate is 6.25% (2/32), with a one-day miss streak. Its issue is already tracked.
• Weekly Network Domain Set Audit: one missing-state read in its only observed run. The workflow successfully wrote the state file afterward, so this looks like an initial cache seed; monitor the next run before opening an issue.
• GitHub API Consumption Report Agent: the recorded first-run miss was followed by a successful cache read. The latest run had no explicit cache operation evidence.
• No volatile run_id cache key without restore keys was confirmed from the available run metadata.

Healthy Workflows

These workflows had observed cache hits in the available 14-day records:

Workflow	Cache Hit Rate (14d)	Last Miss
CLI Version Checker	100% (3/3 observed runs)	None observed

---

Issues Created Today

No new issues created — the repeated AI Moderator and Daily Go Test Parallelizer problems are already tracked; the other misses were isolated or followed by a cache hit.
