Pattern
Evidence Supply Chain
Keep every consequential operational claim connected to its source, custodian, transformations, and useful life. The result is an evidence chain a reviewer can follow in both directions, from the real event to every derived field and decision. Provenance shows where a claim came from, not that the source is correct.
Inputs
Claims, source events, systems, transformations, timestamps, custodians, access rules, and known failure history.
Method
Map provenance from the real event to every derived field and decision. Set source priority, conflict handling, freshness, authenticity checks, and retention.
Output
An evidence chain a reviewer can follow in both directions.
Boundary
Provenance shows where a claim came from. It does not make the source correct.
Stop
Stop using a claim when its source, transformation, permission, or freshness cannot be established.
