What remains unresolved: public research identified advertised processes, prices and policy examples, but did not establish independently verified supplier success rates, cloth provenance for a particular order or a complete Vietnam-workshop/US-fitting partnership. Those questions require commission-level documents and direct verification before a supplier can be recommended for a specific executive.
