[cache-strategy] Fix cache miss in Daily Go Test Parallelizer

[github-actions]

Cache Strategy Problem: Daily Go Test Parallelizer

Severity: 🟠 High

Workflow: Daily Go Test Parallelizer
Analysis Date: 2026-08-28
Issue Type: Misconfigured cache

---

Problem Description

The workflow declares cache-memory: true and the prompt explicitly requires it to round-robin through test files using /tmp/gh-aw/cache-memory/go-test-parallelizer/state.json. After 9 observed runs across 2026-08-27 and 2026-08-28, that state file is still absent, which means the workflow is not persisting its position and is effectively cold-starting every time.

Evidence

• Miss streak: 2 consecutive analyzed days
• Miss rate (14d): 100%
• Last cache hit: never
• Observed runs: 9
• Rebuild excess tokens (14d): 1,030,663
• Log signals: Prompt says Read /tmp/gh-aw/cache-memory/go-test-parallelizer/state.json when it exists and Always create /tmp/gh-aw/cache-memory/go-test-parallelizer/ and write the last path ... to state.json, but /tmp/gh-aw/cache-memory/go-test-parallelizer/state.json is missing after the runs.

Recommended Fix

1. Persist the state file on every successful agent completion so state.json survives to the next run.
2. Add a post-write existence check before the cache-memory commit/upload steps to fail fast when the expected file is missing.
3. Confirm the next run reads the prior value instead of reinitializing from the first test path when the file should already exist.

Expected Impact

If fixed, this workflow should stop reprocessing the same leading test files and materially reduce wasted agent work across its frequent daily runs.
