⚡ 60-Second Elevator Pitch Talking Points
- Immediate Triage: Partially applied. Resources created before the failure exist in the cloud AND in state. Resour
- Run targeted verification commands before modifying configuration.
- Automate permanent guardrails (CI check, alerts, IaC policy) to prevent recurrence.
