🏥 CI Failure Investigation - Run #22103122541

Summary

• The fuzz job completed its tests but finalizing the fuzz-results artifact hit a 403 Forbidden, so the artifact never finished uploading and the job reported failure.

Root Cause Analysis

actions/upload-artifact@ea165f8d65b6e75b540449e92b4886f43607fa02 could not finalize fuzz-results after the fuzz suite succeeded because Azure returned Failed to FinalizeArtifact: Received non-retryable error: Failed request: (403) Forbidden: Error from intermediary with HTTP status code 403 "Forbidden", so the artifact never landed.

Failed Jobs and Errors

• fuzz – the upload-artifact step finalizing fuzz-results failed with Received non-retryable error: Failed request: (403) Forbidden: Error from intermediary with HTTP status code 403 "Forbidden".

Investigation Findings

1. Every fuzz test reported PASS, proving the code under test is healthy.
2. The failure occurs after the tests finish, in the upload-artifact step, meaning the artifact never exists for downstream consumers.
3. Downstream coverage/comparison jobs will see missing artifacts and could misreport unrelated tests unless upload artifacts are confirmed successful.

Recommended Actions

• Re-run the workflow so the artifact upload can finish; this 403 plays out like a transient Azure permission hiccup.
• If the 403 recurs, wrap the fuzz artifact upload with retries (or a custom uploader) and surface missing artifacts before downstream jobs start.

Prevention Strategies

• Add instrumentation to detect failed actions/upload-artifact steps and short-circuit downstream comparisons when their inputs are absent.
• Add retries or a resilient wrapper to artifact uploads that encounter 403s so intermittent Azure responses don’t cascade into CI failures.

AI Team Self-Improvement

Treat Failed to FinalizeArtifact 403 responses from actions/upload-artifact as an infrastructure issue: re-run the workflow or add retries instead of assuming the tests themselves regressed.

Historical Context

• Issue [CI Failure Doctor] CI Failure Investigation - Run #34708 #14811 (Run #34708) documented the same 403 while finalizing the test-result-integration-Workflow Cache artifact.
• Issue [CI Failure Doctor] CI Failure Investigation - Run #35122 #15185 (Run #35122) saw the upload path fail with Failed to FinalizeArtifact: Unable to make request: ECONNRESET, showing the same artifact path is fragile.
