Real hardware has no serial console, so a kernel crash only leaves a
frozen screen. Every dump_lines() report now also renders the crash
text as a scannable QR below the white-on-red band (photograph the
screen instead of relaying text).
- rsnix/src/qr.rs: from-scratch no_std/no_alloc byte-mode QR encoder
(EC-L, v1..v40, .bss statics only — safe on the fault path):
RS over GF(256), codeword interleave, zigzag placement, 8 masks with
N1-N4 penalty auto-selection, format/version info.
- gop.rs: dump_qr() joins dump lines into a static buffer, truncates
with '...' at the v40-L capacity, encodes, and renders centered
black-on-white with a 4-module quiet zone.
- tools/qrcheck: host harness (embedds qr.rs) + qrcheck.py cross-check
against segno's placement primitives. Verified bit-exact: 12
versions x 8 masks forced, plus auto-mask choice matches segno's
penalty evaluation. Caught 3 encoder bugs (multi-block interleave
offsets, transposed version info, mask eval ordering).
- QEMU e2e: page-fault dump screendump decodes via zbarimg, content
matches the serial log line-for-line.
- test-msg.sh and test-fault.sh both PASS; debug+release 0 warnings.

- IDT with 256 entries, loaded via lidt (CS read from current context)
- PIC 8259A remapped to vectors 32-47, timer+keyboard IRQs unmasked
- PIT channel 0 at ~100 Hz (mode 2, rate generator)
- PS/2 keyboard IRQ (IRQ1 → vector 33): reads port 0x60, pushes byte
to lock-free SPSC ring buffer
- Timer IRQ (IRQ0 → vector 32): sends EOI, increments tick counter
- ps2::poll_key() now reads from ring buffer with cli/sti+hlt for
race-free sleep (instead of busy-polling the data port)
- build.rs: use idiomatic Result<_, Box<dyn Error>> return type
- tools/qemu.sh: fix SC2207 shellcheck warning

- Bare-metal x86_64 UEFI kernel (PE32+, no libc)
- GOP framebuffer + 8x16 bitmap font
- PS/2 keyboard (polling, scancode set 1)
- UART 16550 serial driver (COM1, 115200 8N1)
- Bump allocator as #[global_allocator] (alloc::String, Vec, format!)
- UEFI memory map capture (static buffer, ADR 0001)
- Shell with 7 commands (help, echo, clear, hello, info, mem, halt)
- Dual output: GOP framebuffer + serial console
- Makefile: run, run-gui, debug, release, image targets
- tools/: qemu.sh, boot-image.sh, debug-kernel.py
