Retain message identity and origin across gateways
Data Engineer · Trigger: The same event is republished by multiple intermediaries.
Simulated fixture data. Every record, receipt and timeline entry on this screen is demonstration material. It is never production evidence.
Acceptance
2 of 3 steps satisfiedA multi-hop test will distinguish one source event, repeated deliveries and any genuinely new derived event.
Run the remaining steps below. The result is read back from record state — nothing here is a toast.
Normal path
An application API or event stream is acquired with a pinned contract and a backlog inside budget.
Step 1. Test acquisition, pagination and checkpoint recovery.

Moves the record and writes evidence. Permission: remediate.
Acceptance for this step: backlog = within budget

Alternate path. The provider changes shape or rate-limits: raise the incident against the acquisition stage.
