[aw] Code Simplifier: 4-day persistent failure streak — needs root-cause fix (P1)

[github-actions]

Problem

Code Simplifier has been failing for 4 consecutive days (Jun 9–12, 2026) with escalating failure modes:

Date	Run	Failure Mode	AIC Used
Jun 9	§27184225535	Agent failure	—
Jun 10	§27253757407	AIC limit exceeded	~1K
Jun 11	§27324513461	AIC limit exceeded (#38499)	~1K
Jun 12	§27395179213	Engine failure: bash permission loop (#38783)	4.2K

Root Cause Analysis

Jun 12 engine failure (new pattern): The Copilot engine session for Code Simplifier has a restricted bash allowlist that blocks Go binary execution. The agent looped trying workarounds, burned 4.2K AIC (4× normal budget), and the engine terminated unexpectedly.

Jun 9–11 pattern (AIC exceeded): Workflow was already looping — hitting the 1K AI credits cap — masking the underlying permission issue.

Recommended Fixes

1. Investigate whether bash allowlist change affected Code Simplifier's session (Jun 8 was last success)
2. Prompt fix: Code Simplifier should not attempt go build for validation — remove or guard that step
3. If Go execution is needed, set max-ai-credits: 2000 in the workflow frontmatter

Day 5 Update — 2026-06-13

Run: 27456907583
Date: 2026-06-13T04:45Z
Failure mode today: Engine rate-limited (HTTP 429) — 316.9 AIC consumed before provider rejected

Date	Failure mode	AIC
Jun 9	Bash allowlist blocks Go binary	~400
Jun 10	AIC exceeded (loop)	~800
Jun 11	Engine crash (OOM/runaway)	~1,200
Jun 12	AIC cluster, bash permission loop	~4,219
Jun 13	HTTP 429 rate-limited	316.9

5 consecutive failures. The Jun 12 runaway (#38809, now closed) consumed 84% of daily AIC budget (4,219 AIC); today the provider responded with rate-limiting. This confirms the root fix from #38809 has not yet been applied.

Still needed:

1. max-turns: 30 to cap runaway turns
2. Fix bash allowlist to permit Go binary execution
3. max-ai-credits: 1500 to bound AIC usage
4. Provider quota review (rate-limit from yesterday spike)
