Configure the runbooks contract

Implement types or schemas around ingest worker + queue metrics so illegal states are unrepresentable at the boundary. For executable queue-backlog runbook for embedding ingestion pipeline, trusted inputs come from sessions, signatures, pinned digests, or workload identity — not from free-form model text. secondary on-call clearing ingest.lag_minutes > 45 should be able to read the contract and know which fields are optional, which are enumerated, and which abort the request. Constructors and boot paths must not perform provider side effects; injection points keep tests honest.

Document required env vars in .env.example with placeholders only. Rotation story belongs later, but the contract already forbids printing secrets and forbids defaulting to fail-open when a dependency is missing. Invariant to encode in types/tests: every command is copy-pasteable; mutating steps need change ticket; verify after each step. If a config number lacks units, fix the name (timeout_ms, rpm_hard) before writing logic.

kubectl get deploy ingest-embed -o wide

Create fixtures for the golden path and for INC-INGEST-9021. Name files after the behavior (429-retry-after.json, cross-tenant.json, empty-citation.json) rather than test1. Each fixture carries expected status/code. This kit is the shared language for validation and failure pages.

Compatibility promise: additive fields may appear only if readers ignore unknowns safely; breaking changes bump a version visible on the wire. For AI payloads, size limits arrive before JSON parse when hostile blobs are a risk. Document how clock skew, idempotency keys, and tracing headers travel through executable queue-backlog runbook for embedding ingestion pipeline. If you use feature flags later, the contract already states that flags are not authorization. Link each config knob to a unit and a failure mode (“0 means disabled” vs “0 means divide-by-zero”). A peer reviewing the PR should find INC-INGEST-9021 named in a comment on the adversarial fixture.

Generate OpenAPI or a typed client only after the hand schema is stable for one fixture round-trip. Record how errors look on the wire — problem+json, envelope, or bare status — and stick to one. Clock sources must be injectable for skew tests. If webhooks appear later, document signature header names now even as TODOs. Keep sample payloads UTF-8 and free of real emails. Add a makefile or npm script that validates schemas without network. In this chapter the product is executable queue-backlog runbook for embedding ingestion pipeline, the human stakeholder is secondary on-call clearing ingest.lag_minutes > 45, and the incident id you design against is INC-INGEST-9021. Re-state the oracle in your notes — drill INC-INGEST-9021: lag 60→5 minutes in ≤ 25m following runbook v1.4 — and keep the invariant visible: every command is copy-pasteable; mutating steps need change ticket; verify after each step. Track drill_completion_minutes and lag_minutes as the scoreboard. Surface under change control: ingest worker + queue metrics. If you only have forty minutes, finish the fixture for runbook says 'restart something' without naming deployment or verifying lag before polishing UI. Promotion language stays ternary: promote, hold, or roll back based on evidence, not hope.
