- 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

Warning cleanup (cargo check + clippy now 0 across the workspace):
- Migrate all 21 static_mut_refs sites to &raw mut accessors (fat, gop,
ps2, vt, ahci, interrupts, memory) so edition 2024 won't deny them
- panic = "abort" profiles: bare cargo check/build now works without
nightly/-Zbuild-std
- Wire TICKS in the timer ISR (it was never incremented, so the vt scroll
batching trigger was dead code)
- Clippy: efi_main becomes unsafe extern "efiapi" with a # Safety doc,
KeyBuf::new uses inline-const array repeat (no interior-mutable const),
editor main loop is a while-let, PIT control byte regrouped
- [workspace.lints.clippy] allows result_unit_err + needless_range_loop
(deliberate kernel style); large_enum_variant allowed on LineInput
- Drop now-stale static_mut_refs allow from the rsdos bin
FAT32 correctness fixes (both pre-existing, exposed by the SFN fix):
- Unique 8.3 short names: to_8_3() never disambiguated collisions, so
files sharing a long-name prefix got identical SFNs and fsck reported
duplicate directory entries. Add dir_short_names() + unique_short_name()
(~N tails, Windows-style) and force LFN when the SFN changes.
- Multi-cluster directories: scan_dir/dir_short_names stopped at the first
0x00 slot, hiding every entry written into a chained cluster (writes
failed with 'cannot write', duplicate SFNs accumulated); add_dir_entry
now packs the cluster (0xE5 deleted-markers) before extending so other
FAT readers (mtools, Windows) see the continuation too.
Other: delete dead fields (Disk.fis, Volume.fat_count), drop timer_irq/
keyboard_irq/rendered, refresh_and_exit is a documented unsafe fn, CONTEXT
.md corrected (stable toolchain, IRQ input, 4-crate layout), .gitignore
excludes .pi-subagents artifacts.
Validated: cargo check/clippy/fmt clean, make test-disk PASS on fresh and
reused images (incl. two directory-chain extensions and ~10 SFN tails),
editor round-trip smoke test PASS.

Kernel now has the classic UNIX console split, so full-screen ANSI apps
can run in ring 0:
- vt.rs: terminal emulator owning the text screen — cell grid (char +
fg/bg), logical cursor (inverse-video), scrolling, and a small ANSI
CSI parser (cursor position H/f, erase J/K, moves A-D, SGR 16-colour
with correct ANSI→VGA mapping, cursor show/hide ?25). Blits only
changed cells; scroll shifts cell grids + pixels and re-rasterises
only the exposed bottom row. gop_println!/clear_screen now render
through the vt; gop.rs is the raw rasteriser (colored glyph blits,
pixel shift).
- tty.rs: line discipline — canonical read_line (echo, line buffer,
^C cancel, ^D EOF) moved out of the shell, and raw read_byte that
translates KeyEvents to the terminal byte protocol (arrows → ESC[A-D,
Backspace → 0x7f, ^X → 0x18, Ctrl+arrows → ESC[1;5A-D, Home/End/PgUp/
PgDn/Delete). interrupt_pressed() stays for streaming commands.
- ps2: generic Ctrl(char) + CtrlArrow events (was: only CtrlC/CtrlD).
- rsdosedit: no_std port of the RNG rsedit editor as the first real
app — undo, syntax highlighting (verified green/gray/yellow on the
framebuffer), search, word nav, smart indent, ^S save / ^X exit /
^X again to discard. termios → tty raw, stdout → vt, std::fs → VFS
(ramfs), SIGWINCH → fixed geometry, force-exit window → key counter.
- shell: 'edit <path>' command; read_line/strbuf moved to rsnix.
- CONTEXT.md: layout + milestones + known-issue perf notes.
Verified in QEMU: full edit → type → arrow-move → insert → save → exit
round trip with byte-exact file content; ANSI colors via screendump.

No functional changes — boots to shell prompt identically.
