correlationId
A unique identifier minted at API ingress and propagated through every log, event, webhook header, and audit row for a single logical request.
The correlationId is the universal join key. When a customer reports an issue, ask for the correlationId from the error response (every RFC 7807 error returns it). One log query, full timeline.
Pass X-Correlation-Id on inbound requests to provide your own; otherwise, api-service mints one as ULID.
