Federate a query without persistent replication
Authorized Data Consumer · Trigger: Restricted or large history should remain at its source.
Simulated fixture data. Every record, receipt and timeline entry on this screen is demonstration material. It is never production evidence.
Acceptance
2 of 4 steps satisfiedQuery evidence will identify the source, access policy, range, completeness and any retained cache.
Run the remaining steps below. The result is read back from record state — nothing here is a toast.
Normal path
Historian history is federated, with a bounded backfill planned and its evidence verified.
Step 1. Test acquisition and confirm checkpoint behaviour.

Moves the record and writes evidence. Permission: test.
Acceptance for this step: acquisition = healthy
Step 2. Preview the bounded impact of the history request before running it.

Exception path
A federated query will not bypass source permissions or create an undeclared retained copy.
Alternate path. The historian throttles or refuses the window: escalate rather than retry blindly.

Workflow as specified
CoreSync will broker an authorized bounded query, push down permitted filters and return normalized results with provenance and cache policy.
