Pull request overview
Adds a resolve(tee_id) API to the TEE connection layer so backend OHTTP relays can pin requests to a specific on-chain TEE while still letting the SDK manage TLS pinning and the x402 HTTP client. StaticTEEConnection.resolve() always returns the configured endpoint; RegistryTEEConnection.resolve() looks up the requested id in the registry, builds (and caches) a pinned client for it, and raises ValueError if it is not active. An LLM.resolve_tee_connection() wrapper exposes this on the public client.
Changes:
- Add
resolve()toTEEConnectionInterfaceand both implementations, with a shared_normalize_tee_id()helper (lowercases, ensures0xprefix). - Factor
RegistryTEEConnection._connect()into a reusable_connect_to_tee(TEEEndpoint)and add a_active_by_tee_idcache for per-id resolutions. - Expose
LLM.resolve_tee_connection(tee_id)and re-exportActiveTEEfromtee_connection.
