Global change brief
Execution context
High = customer-visible breakage risk
Medium = controlled degradation or stale output
Low = narrow blast radius
Operator rule
Before you execute
Every selected change should have: a current-state note, a rollback note, and at least one smoke test checked. This page is intentionally preflight-only — it does not push changes.
Use Mission Control for live confidence, then open this lab when a planned AWS change needs explicit blast-radius discipline.
