PLATFORM RC-95 (no-op) — Webhooks ops runbooks + SLOs (v1) (rc95)

RC-95 defines operator-facing contracts for webhooks reliability:

• SLO / SLI definitions
• alerting policy and thresholds
• incident runbooks (what to inspect, what to mitigate, what evidence to capture)

This OpenAPI document is contract-only:

• It intentionally defines no HTTP endpoints (paths: {}).
• It exists so the public API reference (Redoc) can present the operational contracts in one place.

Canonical RC docs:
