Login:
- Add console_login() (security/auth.c): an interactive boot-time username /
password gate rendered on the framebuffer console before any session starts.
It blocks until valid credentials are entered, masks the password, scrubs it
from the stack, and sets the current user. Default account is SUB / SUB, shown
as a hint. Wired into the boot handoff in kernel/main.c ahead of both the GUI
desktop and the emergency TTY shell.
Configure:
- scripts/kconfig/menuconfig.py: fix the architecture (and optimization) picker.
The lxdialog front-end used --radiolist, where <Enter> confirms the ORIGINAL
choice and only <Space> moves the dot -- so highlighting a new architecture
and pressing <Enter> appeared to do nothing. Single-choice groups now use
--menu (with --default-item), where <Enter> selects the highlighted row
directly. Also stop the unconditional save-on-exit from overriding an explicit
"No" at the exit confirmation.
Verified: SUB/SUB logs in (injected via QEMU monitor) -> "Login successful" ->
desktop starts; the desktop stays blocked until login. dialog --menu selection
of aarch64 persists to .config/autoconf.h and retargets `make`. Clean build on
x86_64/aarch64/armv8i.

Kernel / memory:
- mm/kmalloc.c: fix "Heap: Out of memory" under the GUI. The desktop allocates
three full-screen 32-bit buffers (~11MB) which overflowed the fixed 16MB pool.
The heap now starts at 32MB and grows on demand from the PMM (16MB regions),
with region-safe coalescing (only merges physically adjacent blocks) so growth
never corrupts across separate PMM allocations. Adds heap_get_grow_count().
Build / run:
- Makefile: merge `run-gui` into `run` so `make run` boots into the graphical
desktop; add `run-headless` (serial-only via QEMU_CMD), bump guest RAM to
256M, update .PHONY and help.
Configure:
- scripts/kconfig/menuconfig.py: gate the curses UI behind isatty() on stdin and
stdout so non-interactive `make configure` stops emitting "nocbreak() returned
ERR" and falls cleanly through to the non-interactive writer.
GUI / userland:
- gui/gui_apps.c: rebuild the System Monitor from hardcoded values into live
telemetry -- real heap used/total/free with a colour-shifting bar, a scrolling
heap-utilisation graph, the grow counter, and real PMM RAM figures.
- lazybox `free`: report how many times the heap has grown.
Auth:
- Default login is now SUB / SUB (Kali-style username==password), seeded first
as the primary uid-0 account and set as the logged-in user; root kept for
compatibility. Hardcoded "root" defaults (whoami, su, passwd, ssh, sshd
session) updated to SUB.
Verified: clean build on x86_64/aarch64/armv8i; GUI boots with 0 OOM/0 panic;
auth engine initialises cleanly; `make configure` fallback is clean.
