The compatibility suite is pinned to T3 server bases `0.0.28` and `0.0.29`
(including `*-nightly.…` builds of those bases) against upstream contract
commit `5d34f9ff235115d43a6cb4b4561d10badf218b87`. Other server versions are
reported as **Incompatible** until Microbridge verifies and ships their contract.
The adapter opens threads with T3 Code's semantic deep link. Reasoning effort
stays disabled because the current paired HTTP snapshot includes the selected
value but not the provider/model option descriptors needed to choose the next
valid level safely. Microbridge does not fake this with key presses or private
desktop state.

The compatibility target is the contract present in `pingdotgg/t3code` as of
July 18, 2026. Authentication failures return to **Needs setup**; transport
failures show **Connecting** and retry with the existing paired credential.
The compatibility target is the orchestration shell/dispatch contract present
