🏥 CI Failure Investigation - Run #32917

Summary

The unit test job in run 32917 failed immediately because go test could not download any of the required modules; every (proxy.golang.org/redacted) request returned 403 Forbidden`, so the build never started.

Failure Details

• Run: 32917
• Commit: af93555
• Trigger: push

Root Cause Analysis

The go test command pulls dependencies directly through proxy.golang.org. In this environment the proxy replies with 403 Forbidden for every module (e.g., github.com/charmbracelet/huh@v0.8.0, github.com/cli/go-gh/v2@v2.13.0, github.com/fsnotify/fsnotify@v1.9.0, github.com/charmbracelet/bubbles@v0.21.1-0.20250623..., golang.org/x/term@v0.39.0, etc.). Without those downloads the compilation/setup of cmd/gh-aw and the internal tools fails, so the unit test job exits with Process completed with exit code 1 before any tests actually run.

Failed Jobs and Errors

• test (ubuntu-latest): Set -o pipefail && go test ... → multiple Get "(proxy.golang.org/redacted) Forbidden errors, so module download and build fail before tests execute.

Investigation Findings

• The output shows the Go toolchain attempted to download numerous dependencies (networking, console, workflow, parser packages) and each attempt hit a 403 response from proxy.golang.org.
• Because the modules listed are public, the most probable upstream cause is that the runner treats the module path as private (e.g., due to GOPRIVATE/GONOPROXY settings) or the proxy access policy disallows the request, so the proxy refuses to serve the zipped modules.

Recommended Actions

• Confirm the runner’s Go environment variables: verify GOPRIVATE, GONOPROXY, and GOSUMDB are not inadvertently covering public modules (e.g., github.com/...), and ensure GOPROXY=(proxy.golang.org/redacted),direct is allowed from the runner.
• If the proxy really is blocked or requires credentials, switch to a permitted mirror or GOPROXY=direct so the modules can be fetched directly from GitHub.
• Consider caching the modules (via setup-go cache) so repeated downloads do not hit the forbidden gate.

Prevention Strategies

Document the expected Go proxy/mirror configuration for CI runners, and include a make test-unit run in a clean environment before landing commits to catch missing proxy permissions earlier.

AI Team Self-Improvement

When investigating test failures caused by Go module downloads, always (1) check for 403 Forbidden responses from proxy.golang.org, (2) verify GOPRIVATE/GONOPROXY settings, and (3) try GOPROXY=direct locally to reproduce the failure before assuming the source code changed.

Historical Context

No prior occurrences were recorded for this run ID; the logs for run 32917 are the only observed failure of this signature so far.
