Home app actions: host checkpoint

2026-10-01, x86_64 host. Source adds mouse secondary-click menus to Home, dock and All apps. Touch hold remains grab-and-move; no touch menu gesture is added. Primary activation uses Sway focus history and shared desktop-ID, StartupWMClass and executable fallback matching. Explicit New Window uses the declared desktop action when present, otherwise a fresh GIO launch where single-window/DBus metadata permits it. Named actions come from the desktop entry, not shell-invented flags. Stale entries/windows are revalidated.

Menu metadata/window queries run off the Wayland dispatch thread with bounded IPC reads. Outside/secondary clicks dismiss; canceled and dragged contacts cannot activate rows. Trackpad pan release cannot become a menu click. Private-marked windows conceal their titles. Menus use the active shell theme.

Command in the native Nix environment (Cairo, Pango, librsvg, GLib, libxkbcommon, Cargo/Rust from the pinned flake at eb38af2a):

cargo test --offline --manifest-path nix/rust-shell-client/Cargo.toml

PASS: 426 library checks, 22 binary checks and 43 integration checks; one pre-existing timing benchmark ignored. New policy tests cover MRU/mismatched identity, private labels, cancellation/drag and real GIO desktop-action and single-window metadata. Existing Home grab and primary-pointer ownership regressions pass. This is host proof, not compositor menu delivery, a native board capture or finger acceptance. The paired actions scenario, exact cross build and recoverable installation remain separate tasks.
