Ingress & Canonicalization
Force carrier — mediates interactions between systems
Accepts external inputs (webhooks, API calls, scheduled triggers), validates identity, wraps payloads into canonical EventEnvelopes with CorrelationId and HMAC signatures. Returns 202 immediately — never blocks on downstream processing.
Outputs
EventEnvelope + CorrelationId + HMAC signature
Must Never
Decide routing policy, execute side effects, hold workflow state, interpret payload semantics
