CI Failure DoctorCI Failure Investigation - Run #167 (23703759281) - Infrastructure Failure in detection job

[github-actions[bot]]

Summary

The Daily Perf Improver workflow run #167 failed on 2026-03-29 at 07:05 UTC due to an infrastructure failure in the detection job — not a Rust code issue.

Failure Details

Root Cause Analysis

Infrastructure failure in the gh-aw agentic workflow framework (v0.47.1), not in application code.

Failing step: Setup threat detection (Step 6 of the detection job)

uses: actions/github-script@ed597411d8f924073f98dfc5c65a23a2325f34cd
script: require('/opt/gh-aw/actions/setup_threat_detection.cjs').main()

The script setup_threat_detection.cjs failed, causing all downstream steps in the detection job to be skipped:

• "Ensure threat-detection directory and log" → skipped
• "Validate COPILOT_GITHUB_TOKEN secret" → skipped
• "Install GitHub Copilot CLI" → skipped
• "Execute GitHub Copilot CLI" → skipped
• "Parse threat detection results" → skipped

The Rust code is unaffected. The only code change triggering this scheduled run was a Dependabot Cargo.lock update bumping fastembed 5.12.1 → 5.13.0. The agent job completed successfully in ~8 minutes, indicating the core CI pipeline is healthy.

Possible Causes

1. Transient infrastructure error in the gh-aw platform at the time of the scheduled run
2. Breaking change or rollout issue in setup_threat_detection.cjs at v0.47.1
3. Missing prerequisite or permission that setup_threat_detection.cjs expects

Recommended Actions

• Re-run the failed detection job to check if it was transient
• If persistent, review gh-aw framework v0.47.1 changelog or report to the platform team
• No Rust code changes required — the application code is healthy

Prevention Strategies

• Add a fallback or continue-on-error: true to the Setup threat detection step to prevent the entire detection job from failing on infrastructure transients
• Monitor for recurrence of this specific failure pattern to distinguish transient from persistent issues

AI Team Self-Improvement

Add to instructions.md for AI coding agents:

When investigating CI failures in workflows using the gh-aw agentic framework, check whether the failure is in the detection job's Setup threat detection step. If so, this is an infrastructure-level issue with the gh-aw platform tooling (/opt/gh-aw/actions/setup_threat_detection.cjs), not a code bug. The appropriate action is to re-run the job rather than modifying application code. Always confirm whether the agent job succeeded before concluding there is a code problem.

Historical Context

No similar previous investigations found in the investigation cache. This is the first recorded failure of this type for this repository.

🔁 Recurring Failure — Same Pattern (2026-03-30)

The Daily Perf Improver workflow has failed again today with the identical root cause documented in this discussion.

Run Details:

• Run ID: 23732411653
• Date: 2026-03-30T07:10 UTC
• Commit: 3fa0e5d105b8ebfa8802002edc5fb117ebb237bf (same commit as yesterday's failure)
• Failed Step: Setup threat detection → detection job (Step 6)

Pattern Confirmed:
This failure has now been observed on at least: 2026-03-27, 2026-03-28, 2026-03-29, and 2026-03-30. The agent job continues to succeed each time, confirming the Rust codebase is healthy. The issue is persistent, not transient.

Updated Assessment:
Given 4+ consecutive daily failures, this is not a transient infrastructure blip. The setup_threat_detection.cjs script at gh-aw v0.47.1 appears to be consistently failing in this workflow context. Investigation of the gh-aw platform changes around that version pinned in daily-perf-improver.lock.yml is warranted:

uses: github/gh-aw/actions/setup@1b847e3d0c6d8ebc44cb538c55198da42baa8a78 # v0.47.1

Recommended Next Steps:

• Check if updating gh-aw from v0.47.1 to a newer version resolves the setup_threat_detection failure
• Review the open Dependabot PR ci: bump github/gh-aw from 0.58.3 to 0.62.5 #161 (ci: bump github/gh-aw from 0.58.3 to 0.62.5) — updating the framework version may fix this
• The Rust application code requires no changes
