The hosted gateway returns `401 No client token provided` for every path except `GET /version`. - There is no idempotency key. Retrying a failed `POST /complete`, `POST /chat/completions` or `POST /v1/responses` may duplicate work. The PhariaSearch and PhariaData write surfaces use caller-named `PUT`s instead, which are naturally idempotent. - No rate-limit headers are published. Backpressure arrives as `503` with a queue-full message. - Errors use `{"error": {"message", "type", "param", "code"}}`, not RFC 9457 problem+json. - No public status page, no A2A agent card, and no `/.well-known/` documents are served.
