smix-cli 11.0.0

//! Every CLI command that accepts an OCR selector dispatches past the tree.
//!
//! `OcrText` never matches in the tree: the resolver returns false for it
//! by design, because OCR is a live look at the screen and not a
//! predicate over a dump. A command that takes one and calls `find` or
//! `tap` with it does not fail — it reports that text plainly on screen
//! is not there. Silence is the failure mode, which is why this is a
//! source-level assertion rather than a behavioural one: there is nothing
//! to observe when it goes wrong.
