Example output
A) Executive Summary
- Main risk is cache inconsistency between ISR/edge/CDN causing users to see stale auth state.
- Highest impact flow is [Checkout] with weak degraded behavior on API timeouts.
- Hydration mismatch risk due to mixed client/server rendering in [RSC + client components].
- Rollback risk: old build artifacts may still be served via CDN after redeploy.
- Recommendation: NO-GO until cache invalidation + timeout UI + rollback runbook are in place.
