Rewrite the Installer app on the Montauk Toolkit (Canvas + gui/mtk
widgets, theme, hover states, scrollbar) replacing the hand-rolled px_*
renderer and bespoke TrueType usage.
Add a new "Software" step: an expandable checkbox tree for optional
components (Montauk SDK with gcc/g++, binutils, tcc, lua sub-items;
Games; Office; Internet apps; Printing; experimental httpd and SDR).
Unchecked components' paths are excluded from the install copy, with a
longest-path ownership rule so e.g. sdk/tcc installs even when the rest
of the SDK is deselected. The update flow refreshes only the components
the target already has.
Add tri-state checkbox and disclosure-arrow widgets to the MTK toolkit
(anti-aliased, supersampled).
Merge tcc and lua into 0:/sdk (0:/sdk/tcc, 0:/sdk/lua) and drop 0:/lib:
update tcc config.h, lua luaconf.h, both Makefiles, the devkit clean
scope, man pages and montaukos.org notices.
Make printing optional: init skips printd when 0:/os/printd.elf is
absent.

Groundwork for the GCC driver: a compiler driver must spawn cc1/as/ld
and know whether each stage succeeded.
Kernel: the scheduler keeps an exit-code ledger (pid -> code; pids are
monotonic so entries never alias), published during teardown right
before waiters wake. SYS_EXIT records main()'s return value, SYS_KILL
records 256+SIGKILL, and the exception handler records 256+signal
mapped from the fault vector (#PF/#GP -> SIGSEGV, #DE/FP -> SIGFPE,
#UD -> SIGILL). SYS_WAITPID now returns the code: 0..255 for a normal
exit, 256+signal for a violent death. Process args grow from 256
bytes to 4 KiB (cc1 invocations do not fit in 256), with crt1 now
parsing up to 255 argv entries from a static buffer.
libc: new spawn.h with posix_spawn/posix_spawnp over SYS_SPAWN -
libiberty's pex layer has a posix_spawn backend, so GCC's driver works
without fork. argv is joined into the kernel args string (spaces in
arguments rejected; no kernel quoting), envp is not transferred, and
non-empty file actions fail loudly with ENOTSUP until the kernel can
redirect stdio on spawn. waitpid() now decodes real POSIX status and
the sys/wait.h macros distinguish exited from signaled children.
Shell: prints [exit code N] after nonzero exits and [terminated by
signal N] for killed or crashed children.
Verified on the OS: cat on a missing file reports exit code 1; a
window-close (clean exit 0) stays silent as it should.

0:/usr was a Unix transplant in an otherwise Montauk-native layout.
The SDK now lives at 0:/sdk/{bin,include,lib} (+ ldscripts under
0:/sdk/x86_64-montauk): Montauk-flavored, and a clean unit for a
future per-component installer tickbox. Native binutils is rebuilt
with --prefix=/sdk so ld's compiled-in search paths follow; future
ports configure with --prefix=/sdk.
Also add pathconf() with _PC_* names to the libc: now that realpath
exists, libiberty's lrealpath.c compiles its pathconf fallback path
unconditionally.
Shell command resolution and tab completion updated to 0:/sdk/bin.
Boot-verified in QEMU: setup, login, desktop on the new image with
zero usr/ remnants in the ramdisk.

The devkit target in programs/GNUmakefile stages the native binutils
(as, ld, ar, nm, objcopy, objdump, readelf, ranlib, strip, size,
strings, addr2line, c++filt, elfedit as *.elf) into the image at
0:/usr/bin, plus a target-side sysroot: libc headers, montauk/ and
Api/ SDK headers and the freestanding C++ set at 0:/usr/include, and
libc.a + crt1/crti/crtn objects (with empty libm/libstdc++ stand-ins)
at 0:/usr/lib. ld's ldscripts ship under 0:/usr/x86_64-montauk.
The /usr prefix matches the binutils configure prefix, and the kernel
already resolves driveless absolute paths against the cwd drive, so
compiled-in /usr/lib search paths work natively on drive 0.
The shell resolves commands from 0:/usr/bin (after 0:/os) and tab
completion lists it. When toolchain/native/ has not been built, the
devkit step skips cleanly and the image builds as before.

Grow the Montauk libc enough to cross-build binutils 2.43.1 with
--host=x86_64-montauk. gas, ld, ar, nm, objcopy, objdump, readelf,
ranlib, strip and friends now link as native ET_EXEC Montauk binaries
(staged stripped in toolchain/native/, not yet shipped in the image).
New libc surface: full Linux errno and signal sets, O_* flags with
real O_EXCL/O_APPEND semantics, unlink/rmdir/dup/dup2/getpid/_exit,
kill (SYS_KILL), fcntl, fileno/fdopen, putc/getchar/rewind,
ctime/asctime, strtoll/strtoull/atoll, bsearch, mkstemp/mktemp,
realpath (lexical, drive-prefix aware), mbstowcs/mblen, chmod/fchmod/
umask/utime no-ops (VFS has no modes or settable times), full struct
stat with fake inodes, sscanf field widths (bounded conversions),
SCN*/PRI* completions, wait/waitpid over SYS_WAITPID, and new headers
sys/wait.h, sys/param.h, utime.h, wchar.h, memory.h.
fork/exec/pipe are declared but fail with ENOSYS: binutils never
spawns, and real process plumbing is the posix_spawn milestone, which
needs kernel support (exit status reporting, fd redirection).
TCC's montauk_compat.h shims (unlink, chmod, execvp, realpath, fdopen,
strtoll, strtoull) are retired in favor of the libc versions.

Switch all program and library Makefiles from host g++ (or the
bare-metal x86_64-elf compiler) to x86_64-montauk-g++/gcc and drop the
flags the target now owns: -nostdinc + kernel freestanding -isystem
paths, -m64/-march, -fno-PIC, -mno-red-zone, -mcmodel=small, -static,
-Wl,-m,elf_x86_64, -z max-page-size, --build-id=none. Deliberate
policy flags stay (-ffreestanding, per-app SSE, -nostdlib + link.ld).
Program builds now require the montauk toolchain and fail with a
pointer to build-montauk-toolchain.sh; lib/ and libs/ keep the host
fallback since the toolchain script bootstraps libc through it.
Userspace is also now pinned to the cross GCC instead of drifting
with the distro compiler.

Deleting a big file froze the desktop for seconds: ext2 FreeBlock did 4
synchronous disk I/Os per data block (bitmap + BGDT read/write), and the
file manager deleted single files inline on the desktop main thread.
- Ext2: batch block frees per block group; keep the bitmap resident,
clear bits in memory, flush bitmap + BGDT once per group transition.
Also covers the truncate-on-overwrite path.
- Ext2: refuse to mount volumes with block size > 4096; temp buffers
throughout the driver are single 4 KiB pages, so larger blocks would
overflow them (our mkfs always uses 4K).
- Files: route single-file deletes past 4 MiB to the background worker
+ progress dialog; refuse (instead of stalling inline) when another
file operation already owns the worker.

Ship a default wallpaper (blossoms by Nikhil Kumar, Unsplash License) in
a new 0:/os/wallpapers/ directory for OS-provided imagery, staged from
programs/data/wallpapers/. login.elf falls back to
0:/os/wallpapers/default.jpg when the desktop config names no wallpaper
or the configured file cannot be opened. Attribution added to
THIRD-PARTY-NOTICES.txt and man legal.

bdAddr bytes are stored LSB-first (HCI wire order) throughout the stack,
but the bluetooth app and btbonds tool formatted them LSB-first too, so
every MAC displayed byte-reversed. Print addr[5] down to addr[0] instead.
Display-only change; wire-order parsing and syscalls untouched.

Bump the selected character's name (16->19) and metadata (14->15) sizes, and
lay them out as a two-line block vertically centered on the preview glyph box
instead of top-aligned.

Render the button in its disabled state during the post-copy confirmation
window, matching the Bluetooth app's greyed-out "Scanning..." button.

Instead of a separate "Copied to clipboard" line beside the Copy button, flip
the button's own label to "Copied" for ~1.6s after a copy, then back to "Copy".
Simpler and keeps the footer uncluttered.

The hand-rolled Copy button (bold, custom-shaded accent fill) and the floating
accent "toast" pill both looked out of place. Replace the button with the
canonical mtk::draw_button (BUTTON_PRIMARY), matching the Refresh button in
Devices and buttons elsewhere. Replace the floating pill with a plain
"Copied to clipboard" status line in the footer, right-aligned beside the Copy
button, that fades after ~1.6s — no overlay drawn over the character grid.

The scrollbar was placed inside the padded tile grid, leaving a gap above it
(below the tabs) and beside it (before the window edge). Give the scrollbar
its own viewport spanning the full panel between the tabs and footer, flush to
the right window edge, like the Devices/Music apps. The tile grid keeps its
margins and simply reserves the scrollbar width plus a gap on its right.

Replace charmap's hand-drawn scrollbar with the mtk scrollbar widgets
(scrollbar_track_rect / scrollbar_thumb_rect / draw_scrollbar), matching the
Devices and Music apps: standard 12px track colored SCROLLBAR_BG/FG with a
draggable thumb. Adds thumb drag, track-click-to-jump, and hover highlight
(mirroring devexplorer's handling); the tile grid reserves an SB_GUTTER on the
right sized from mtk::SCROLLBAR_W. The bar auto-hides when the set fits.
