List recently chosen models
The models the caller chose in a client, most recent first, bounded — the shortlist a model picker offers above the full catalogue so somebody alternating between two models never scrolls for either. The head of this list is also the default a session the caller opens with no explicit model adopts. A model no longer in the catalogue is absent here rather than listed as unusable.
Autorizações
Enforced on every transport, with no exempt operation. A person's request must carry a JWT issued by the configured identity provider, which the host verifies itself against that issuer's key set: signature, issuer, expiry, and the person and organisation it names. Requests without a valid one receive 401 NRY-0011 — except a request with no token on a laptop's socket from the OS user the kernel names as the host's own, which is that machine's user.
