Project P.I.T.T. Controller Support Scope
Controller Support Scope: Valve's compatibility record describes default controller functionality on Deck.
Valve's compatibility record describes default controller functionality on Deck. It does not publish every custom binding for every controller.
Check the specific platform state
Confirm device selection, then identify the exact missing action. Compare its in-game binding with the recorded input instead of using an invented universal button map.

Avoid a broader claim
An official listing establishes the fields it actually publishes. It does not validate every community workaround, future feature, performance expectation or cross-platform save assumption. Keep an older compatibility test dated instead of calling it a new gameplay run.

A reversible diagnostic record
Keep the selected platform/runtime, input device and exact action together. If a change fails, return to the prior configuration and preserve the save backup; do not combine a file restore, a controller reset and a renderer change in one unexplained experiment.

Evidence and verification limits
Source retrieval confirms what a source says, not a new in-game replay. Patch notes retain their version; community observations retain their limitations.
