History

Admin 6c6ebff2ec platform, widgets, wm: a touch that is taken away is cancelled, never released -- in the WM's phone skin the mouse now reaches the foreground app as a touch, and scrolling Mail then lifting opened the message under the finger: a list that took over a drag had no way to tell the pressed row it lost the press, and the same happened on real phones. Cancellation is now a contract. `Event::FingerCancel` and `FingerUpEvent.cancelled` carry it; `was_tap()` rejects it and no long press fires. `claim_finger_gesture` makes one owner per finger: PortalList and ScrollBar claim only with touch travel along their own axis (mouse drags scroll as before), and every loser, ancestors included, gets its terminal cancel in the same dispatch and never moves again. Pressed rows are cancelled before a list recycles them, cancels reach hidden widgets, and captures retire only after every consumer sharing the area has seen the cancel. iOS touchesCancelled and Android ACTION_CANCEL arrive as cancels and end an internal drag without a Drop. The WM relays `StudioToApp::MouseCancel` (appended, existing tags pinned) only to children that advertise it; inside a child it dispatches as FingerCancel. Widgets and apps that activated, committed, dropped, flung or resampled on any release now clear their state without acting (buttons, radios, menus, DataGrid, Kanban, Carousel, WheelPicker, RadialMenu, Modal, Dialog, Popover, colour controls, video hold-to-pause, maps, the Files treemap and tiles, Weather, Clock, AIChat, fab, flowgraph and more). The WM phone shell rides on it: the simulated finger in the desktop skin, time-based release velocity (80 ms window, stale after a 120 ms rest), one critically damped spring (k 900, c 60) seeded with that velocity for paging, drawer, recents and app open/close, an 8 pt / 1.2x axis lock latched through release, a drawer that tracks the finger 1:1 and draws opaque over the home tiles, hold-to-Recents precedence, launches that zoom from the icon actually drawn with an opaque launch card, no ghost card on close, and one cancel/reset path for rotation, resize, focus loss, style switch and keyboard navigation.
