Guardrails That Stop It

• Owner-Per-Role: Every incident must have an assigned owner for Command, Comms, and Execution.
• Evidence-First: Metrics, traces, and logs must be captured before any high-risk production change.
• Mandatory Postmortems: All Sev0 and Sev1 incidents require a blameless postmortem within 48 hours.
• AI Boundary Policy: AI tools can analyze and recommend, but humans must own the final decision and execution.

Core SRE Principles

1. Evidence Over Urgency: Act based on confirmed signals (Chapter 10), not on panic.
2. Blameless Response: Focus on system gaps and guardrail failures, not individual mistakes.
3. Controlled Escalation: Follow the severity-based communication and ownership model.

Operating Model (The Incident Team)

• Incident Commander (IC): Strategist. Owns the decision-making and resource allocation.
• Primary Responder: Surgeon. Owns the technical execution and verification.
• Communications Lead: Voice. Owns stakeholder updates and status pages.
• Scribe: Memory. Owns the timeline and evidence logging.

Safe Workflow (Step-by-Step)

1. Detect & Declare: Use Chapter 10 signals or Chapter 13 Guardian alerts to detect a failure. Declare severity.
2. Assign Roles: Identify the IC, Responder, and Comms Lead.
3. Build Timeline: Record every key metric change and operator command in a shared log.
4. Mitigate: Execute the lowest-risk fix first. Communicate status on a fixed cadence.
5. Resolve: Confirm recovery via metrics. Record the time of resolution.
6. Postmortem: Conduct a blameless review and assign hardening actions.

This builds on: AI-assisted guardian (Chapter 13) — on-call uses guardian for triage and enrichment. This enables: Capstone — all core guardrails are now operational.
