battle-tested The GoodGo platform is a fully-fledged, enterprise-grade real estate marketplace with comprehensive monetization, advanced search, AI/ML integration, and operational tooling. All critical features are implemented, tested, and documented. The remaining work (Phase 7 Wave 14) focuses on edge case handling and final validation before full production deployment. IMMEDIATE NEXT STEPS: 1. Review PROJECT_TRACKER.md for remaining 3 issues in Wave 14 2. Run `pnpm test:e2e` to validate all E2E scenarios 3. Deploy with `docker-compose.prod.yml` or Kubernetes manifests 4. Monitor with Grafana dashboards and Sentry ═══════════════════════════════════════════════════════════════════════════════════
