Installed Cartesia boundary
The existing Cartesia speech route is private-only. This public studio does not enable live synthesis or account voice discovery.
- Model discovery uses the existing static model catalog.
- Voice discovery is account-scoped and requires server authorization.
- Speech synthesis requires the configured private owner, an approved voice, and canonical server admission. Its installed output is raw 24 kHz PCM.
Fixtures do not establish provider quality, latency, availability, account entitlement, or production readiness.
