atspicheck is the Phase G1 spike: walks a target app's AT-SPI accessible tree and prints whatever text + bounding-box data comes back, to answer one question before any integration work — does this actually retrieve real, correctly-positioned text? See docs/gui-bridge.md and the plan this was built against.

bridgecheck is a manual smoke test for the GUI-TUI Bridge (internal/bridge): launches a real X11 app (xclock by default) inside a nested Xvfb, captures a few frames, and checks that non-background content actually showed up.

Command extapp-hello is a minimal, runnable reference implementation of TTYPE Desk's out-of-process App SDK protocol (see docs/extapp.md) — a real example for anyone writing an app in a language other than Go, and the fixture internal/surface's ExtAppSurface tests spawn as a genuine subprocess rather than mocking the wire protocol.

Command matrixchat is the Matrix messenger client (apps/matrixchat), run as a standalone out-of-process TTYPE Desk app via pkg/extapprun — see docs/appstore.md and docs/extapp.md.
