[aw] Code Simplifier: regression failure Jun 23 (intermittent post-fix)

[github-actions]

Code Simplifier — Regression Failure (Jun 23, 2026)

Workflow: code-simplifier.lock.yml
Run: §28002501565
Priority: P1

Failure Pattern

Code Simplifier was declared RECOVERED on Jun 22 after PR #40578 was merged Jun 21. However, it has regressed on Jun 23:

Date	Result
Jun 23	❌ failure
Jun 22	✅ success
Jun 21	❌ failure
Jun 20	❌ failure
Jun 19	❌ failure

This alternating success/failure pattern suggests:

1. The fix in PR code simplifier: allowed_issue_fields.cjs; remove drain3_server.py #40578 (allowed_issue_fields.cjs; remove drain3_server.py) only partially resolved the issue, or
2. A separate intermittent failure mode exists (e.g., api-proxy AIC budget, flaky dependency)

Related Issues

• Previous issues: [aw] Code Simplifier failed #39968, [aw] Code Simplifier failed #40431, [aw] Code Simplifier failed #40577 (all CLOSED)
• Fix PR: code simplifier: allowed_issue_fields.cjs; remove drain3_server.py #40578 (MERGED Jun 21)
• AIC Budget tracking: [perf-improvement] AIC Budget Crisis Day 5 — 6-agent cluster expanding, root fix urgently needed #39077

Suggested Investigation

• Compare Jun 23 failure log against Jun 22 success log to identify what differs
• Check if drain3_server.py or allowed_issue_fields.cjs are still referenced in failure path
• Check if AIC/api-proxy budget exhausted by early-morning workflows (Code Simplifier runs at ~04:36 UTC)
• Look for any model rate-limiting or timeout at that time of day

Impact

Code Simplifier workflow fails to run — code quality simplification suggestions not generated.

Jun 24 Update — Failure Continues with New Auth Error Pattern

Run: §28075565507
Date: Jun 24, 2026 04:39 UTC | Reported by: Workflow Health Manager §28078071326

New Error Signature

Authentication failed with provider at (172.30.0.30/redacted) (HTTP 403).
  Check your COPILOT_PROVIDER_API_KEY or COPILOT_PROVIDER_BEARER_TOKEN.

This error repeats 3+ times per run, then the engine exits after partial changes (+60 -75 lines written).

Updated Failure Pattern

Date	Result	Notes
Jun 24	❌ failure	HTTP 403 auth at 172.30.0.30:10002
Jun 23	❌ failure	Auth error
Jun 22	✅ success	—
Jun 21	❌ failure	—
Jun 20–19	❌ failure	—

Analysis

The HTTP 403 from `(172.30.0.30/redacted) (internal copilot provider proxy) points to a credential or proxy configuration issue rather than code logic. Jun 22 success may have coincided with a token refresh that wore off. This narrows investigation: the fix in PR #40578 may be unrelated — root cause is provider auth failing at ~04:39 UTC.

Suggested next steps:

• Check if COPILOT_PROVIDER_API_KEY or COPILOT_PROVIDER_BEARER_TOKEN is expired/rotated
• Verify proxy at 172.30.0.30:10002 is healthy at ~04:39 UTC daily
• Compare Jun 22 run environment vs Jun 24 for credential differences

Priority remains P1.
