How Halo thinks about provenance interoperability
Provenance standards can make media origin and change history more inspectable. They do not, by themselves, prove whether a physical vehicle fact is true. Halo begins with guided observation beside the vehicle, then considers which assertions should travel with the resulting record.
Provenance helps describe media history.
C2PA can help media carry selected signed provenance assertions, including where content came from and how it changed. That context is useful for interoperability because downstream systems can inspect claims attached to the asset instead of relying on a detached note.
That kind of provenance is important, but it answers a different question from the one a dealership has beside a vehicle.
Physical observation is still the first trust problem.
A provenance assertion does not decide whether a depicted vehicle fact is true. It can help explain the media object. It cannot, alone, verify that the right vehicle was observed from the required angles or that a specific physical condition was present.
Halo treats trust as a guided physical-observation and record problem first: guide a person beside the vehicle, verify required coverage, preserve the session context, and then decide which provenance assertions should travel with the resulting record.
The direction is interoperability, not a certification claim.
Halo is not claiming C2PA certification, membership, compliance, or general availability. The direction is to keep the vehicle record compatible with trustworthy media infrastructure while staying honest about what each layer can and cannot prove.
