Where did this unit come from?
Start from the serial number in a customer or warranty question and follow it back through rework and production to the material lots recorded as its inputs. Each step shows its source dataset.
As known at a point in time
Run the investigation as the records stand now, or as they were known at an earlier cutoff. A saved run keeps that boundary, so you can show what was known when you answered.
Share what you are permitted to share
Authorised people can download a saved run as JSON, rechecked against current dataset access. It states its scope and coverage. It is an evidence snapshot, not a certified recall record.
Trials are by invitation and start with one agreed workflow. Scope and arrangements are agreed with you before access.
