Investigate CI Optimization Coach workflow failure (transient, no fix needed)

[Copilot]

CI Optimization Coach workflow failed on run #21907043755 with "Successfully compiled 146 out of 147 workflow files" during make recompile step.

Investigation

Failure characteristics:

• Step 14 "Rebuild lock files" exit code 1
• Commit: 215a84a
• 1 of 147 workflows failed to compile
• No error logs identifying which workflow failed

Reproduction attempts:

• Checked out failing commit → all 147 workflows compile successfully
• Current main branch → all 149 workflows compile successfully
• No code differences explain the failure

Conclusion

Transient failure, likely from:

• System resource contention during build
• Network timeout during validation
• Race condition in parallel compilation

No code changes required. Workflow functioning normally since failure.

If recurs: Add workflow-level compilation logging to identify failing file.
