- ADR 0005: persistent home terminal (full-screen, chrome-less,
bottom-pinned), F1 terminal windows, per-instance vt/tty/shell,
queue-based input for all terminals, and the disk controller
- Glossary: add the Terminal term; update Task/App for the new model
- Add a re-entrant disk lock (DiskGuard over the preemption-depth
counter) and wrap all fs/fat mutating operations per-call
wm: title-bar drag-to-move; stop delivering title-bar gestures to apps2026-08-17T16:58:06Zsalmoniksalmonik@tuta.io2026-08-17T16:58:06Zurn:sha1:0e405aad6bc9f631b9b7a766fb1147fef943f492
- Track the active mouse gesture (none / window-move / app-stroke) so a
press on the title bar becomes a move drag instead of leaking Move
events into the app's content
- Add move_window (clamped to the canvas, repaint old + new regions)
- Always deliver MouseKind::Release so a stroke that ends outside the
window still terminates
Windowed GUI: wm module, input routing, and the paint app2026-08-17T16:56:04Zsalmoniksalmonik@tuta.io2026-08-17T16:56:04Zurn:sha1:5558e3509d020a0e021a77f0617044497b2f2aee
- Add the wm window-manager facility per ADR 0004: overlapping
pixel-surface windows, damage-rectangle compositing, WM-drawn title
bar, focus/minimize/close, and F1-F4 keybindings
- Add gop shadow compositing primitives and vt::repaint_region so the
console stays layer 0 beneath windows
- Route mouse (absolute coords, press/release edges) and keyboard
(focus-aware input pump) to the focused window
- Add the rspaint drawing-program crate (pen, 8 colors, clear) and shell
draw/windows/restore commands
- Extend TaskMsg with AppMouse/Focus/Close and document the design in
CONTEXT.md + ADR 0004
