Identity & idempotency

Workflow: AI hiring surge → enrich & rescore v1
Correlation id: a0469d46b10c44f3
Idempotency key: wf:ai-hiring-surge-enrichment:v1:signal.created:66976a1f-c997-5d46-b8d7-241e1ced320d
Run id: 063d8799-8e45-451b-a3c4-07d1ff81d5fd

The idempotency key is workflow : version : trigger type : event id and is unique in Postgres, so a re-delivered webhook or a double click cannot start a second run for the same event. The correlation id ties this run to the CRM syncs, drafts and audit events it produced.

Guarantees

Idempotent. One run per trigger event and workflow version.
Resumable. Retrying keeps succeeded steps and resumes at the failed one.
Retries with backoff. Transient errors retry per step up to max attempts with exponential backoff.
Dead letter. Exhausted retries park the run for a human instead of dropping it.
