voice_upload_storage_unavailable
No voice-artifact storage is configured on this deployment, so sample/consent uploads are refused before any byte is accepted. The URI-string routes (POST /v1/voice-profiles, …/consent-proof) are unaffected. Also answers the admin stock-reference surface for the same absence.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
