Traceability
Also: requirements traceability, measurement traceability
An explicit chain connecting a claim to its requirement, decision, evidence, or reference.
In projects it links requirements to tests and revisions; in metrology it links results through calibrated references with stated uncertainties.
Example A test record cites firmware revision, requirement ID, setup, and raw log.
Common misconception A link to a final screenshot alone is not a complete traceability chain.
