`make` did not parse at all (missing separator at line 139), so every
make target was dead. The folder also carried three overlapping
launchers (boot.sh, qemu.sh, boot-image.sh) plus a fourth partial one
in the Makefile, `cargo build --package rsdos` copy-pasted eight times,
the QEMU invocation copy-pasted per script, and the test helpers
(fail/wait_log/wait_qemu_exit/qemu_hmp) duplicated in five tests.
New layout:
- scripts/lib.sh: single config (image, OVMF, mem/smp), the one cargo
invocation (build_all), the one QEMU shape (qemu_args), and the test
harness (test_boot, wait_log, wait_qemu_exit, qemu_hmp, sendkeys)
- scripts/build.sh: kernel + every bins/* in one pass
- scripts/mksystem.sh: freshness-aware image build that now stages
every bins/*.efi into /bin/cli|gui (they were never copied before)
- scripts/run.sh: build + stage + boot in one command; --headless,
--debug (GDB stub), --monitor (HMP socket), --fresh, --mem/--smp/
--bios/--image; on Wayland it auto-selects XWayland plus
grab-on-hover so the mouse can be captured (Ctrl+Alt+G toggles)
- scripts/tests/: the five automated tests on the shared harness
- deleted: boot.sh, qemu.sh, boot-image.sh, lib-boot-args.sh,
build-image-release.sh, build-bootloader.sh (rsboot chain dropped)
The Makefile is now a thin wrapper: make run, make test, make system,
make inspect, make help. Two-command flow: ./scripts/build.sh then
./scripts/run.sh (run.sh alone also works).
Stale test assumptions fixed so the suite is green again: test-gfx
waited for "gfx: check" while the shell prints "gfx check: PASS";
test-mouse/test-msg hardcoded msgrecv = task 3 (wm-input took slot 3 —
ids are parsed from the log now); the queue-full probe targeted task 0,
whose exec pump drains its own queue as completion codes (moved to the
cursor task, which never recvs).
Verified in QEMU: make test -> test-disk, test-gfx, test-mouse,
test-msg, test-fault all PASS.

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.
