🎯 Impact Scope Investigation

Usage Location: .github/actions/setup/action.yml:10

Single Usage Point:

- uses: actions/cache@27d5ce7f107fe9357f9df03efb73ab90386fccae # v5.0.5
  with:
    path: |
      ~/.cache/go-build
      ~/go/pkg/mod
    key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }}
    restore-keys: |
      ${{ runner.os }}-go-

Workflows Affected (via composite action):

1. .github/workflows/ci.yml - Test, Build, and Lint jobs
2. .github/workflows/release-please.yml - Release job
3. .github/workflows/update-demo.yml - Update Demo job

Impact Assessment:

• ✅ No changes required to existing cache configuration
• ✅ Cache key format remains identical
• ✅ Input parameters unchanged
• ✅ Output behavior maintained
• ✅ No dependency conflicts identified

Caching Strategy:
The current usage caches Go build artifacts and module dependencies using standard GitHub Actions cache patterns. The update improves proxy compatibility without affecting caching functionality.

💡 Recommended Actions

Immediate Actions:

1. ✅ Safe to merge - This is a straightforward patch update with no breaking changes
2. No code modifications required
3. No configuration updates needed
4. No migration steps necessary

Post-Merge Verification:

1. Monitor CI workflow runs to ensure cache operations continue working as expected
2. Verify cache hit/miss ratios remain consistent
3. Check for any proxy-related improvements if your runners operate behind proxies

Benefits:

• Improved compatibility with proxy servers that reject CONNECT requests with additional headers
• More robust caching behavior in corporate/restricted network environments
• Updated dependencies with latest bug fixes
