// S3 of docs/plans/2026-08-14-request-intake.md — `/fire` incident id derivation. Machine
// failures produce identical signature strings (e.g. `deploy-local:actions-gateway-config-missing`),
// so the incident id IS the dedup key: same project + signature always maps to the same id, which
// makes the store's PRIMARY KEY constraint the atomic claim (see RequestsStore.claimFire).
