Identity & idempotency

Workflow: AI hiring surge → enrich & rescore v1
Correlation id: 017cf13f49ac41db
Idempotency key: wf:ai-hiring-surge-enrichment:v1:signal.created:1f6adcfc-3045-5089-bc25-7302b5ee099b
Run id: dbc31692-d297-44a8-8576-be97e4d1e7ba

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.
