Daily Test Coverage Improver - Coverage Steps Failing: Go Proxy Network Issues

[botantler]

Problem

The coverage steps configuration at .github/actions/daily-test-improver/coverage-steps/action.yml is failing due to network connectivity issues with the Go module proxy (storage.googleapis.com).

Error Details

When attempting to run the coverage steps (specifically go build and go mod download), multiple modules fail to download with "Forbidden" errors:

go: github.com/klauspost/compress@v1.18.2: Get "(storage.googleapis.com/redacted) Forbidden
go: google.golang.org/api@v0.252.0: Get "(storage.googleapis.com/redacted) Forbidden
go: modernc.org/sqlite@v1.40.0: Get "(storage.googleapis.com/redacted) Forbidden
go: github.com/diskfs/go-diskfs@v1.7.0: Get "(storage.googleapis.com/redacted) Forbidden

And several others.

Impact

This prevents:

• Building the KSail binary
• Running tests with coverage
• Generating coverage reports
• Phase 3 of the Daily Test Coverage Improver workflow from proceeding

Root Cause

The issue appears to be a temporary network connectivity problem with GitHub Actions runners accessing the Go module proxy at storage.googleapis.com. This could be:

1. Temporary network issues
2. Rate limiting from the Go proxy
3. GitHub Actions runner network configuration issues
4. Proxy authentication/access issues

Recommended Actions

1. Immediate: Retry the workflow run to see if this is a transient issue
2. Short-term: Check if Go module cache is properly configured in the coverage steps
3. Investigation: Review GitHub Actions runner logs for network-related errors
4. Workaround: Consider using GOPROXY=direct as a fallback in coverage steps if proxy issues persist

Coverage Steps Status

The coverage steps configuration exists at .github/actions/daily-test-improver/coverage-steps/action.yml but cannot be executed due to this network issue.
