FlakeGuard QA Verification Report

Generated on: 2025-08-25
Verification Type: Comprehensive Release/QA Audit
Repository: FlakeGuard Production Monorepo
QA Engineer: Claude Code MAX

Executive Summary

This report presents a comprehensive verification of the FlakeGuard repository against phases P0-P20 requirements. The verification follows strict constraints including GitHub Checks API limitations (≤3 requested actions), short-lived artifact URLs (~1 minute expiry), and production-grade security requirements.

Critical Constraints Verified

  • ✅ GitHub Checks requested_action: Maximum 3 buttons enforced
  • ✅ GitHub Actions artifacts: Short-lived URL handling implemented
  • ✅ GitHub Actions re-run: REST API and gh CLI support verified
  • ✅ Slack interactivity: Bolt for JS + Block Kit wired to backend
