Quality release must be capable of independent review. Procurement personnel can first collect factory order numbers, production-scheduling milestones, vehicle allocation schedules, and change records, then check whether they point to the same contract, lot, or VIN. Documents that cannot be matched may only be marked pending verification; they cannot be used to eliminate verbal inventory or production promises that cannot be tied to this vehicle lot. The final action should follow the boundary of linking payment release to verifiable vehicle progress.
