vocapabledisclosure_opener_missing
This code is registered on two surfaces. The two entries are the same rule enforced in two places, so the meaning below is quoted per surface.
§9.6 · Calls, analytics, billing, and exports
the pinned agent version carries no AI-disclosure opener. A floor control, so its absence refuses the session rather than degrading it - on the browser transport exactly as on the carrier one.
§9.9 · Non-customer surfaces
The pinned agent version carries no AI-disclosure opener. The call does not proceed: the opener is a floor control, so its absence is a refusal rather than a degraded call.
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.
