Unclear Nothing has been read about the tengu_kestrel_moor gate, so whether or how this feature is enabled is unknown.

A new latch, alongside the existing sticky betas and per-turn effort pins, is now stored on the conversation. It is written into the session state file as { type: "atis-latch", sessionId, atis }, merged with "always"/"last-wins" semantics like the existing isolation-latch, and carried through fork and resume via atisLatchAtEntry and the session-state snapshot APIs. Its value originates from client config (atis), and once latched it is preferred over the live config for the rest of the conversation.
