Robert Allan JamesandClaude Sonnet 5 91742e02f4 FABRIC.md item 4.4x: split the REPL prompt into its own bottom strip
Scope expanded from pure CANVAS-rectangle arithmetic (as originally
scoped) to also splitting the REPL prompt/input line out of the
scrollback box into an independent single-line strip, per Captain Bob's
explicit fold-in after the gap was reported (§25.0 rule 3) rather than
silently expanded.

vt100.c: VT100_BOX_ORIGIN_X/Y are no longer hardcoded per-arch literals --
both are now derived from fb_width()/fb_height() at vt100_enable_ttf()
time. New vt100_strip_draw() renders the bottom strip (gray border lines,
bright-white text) directly via the existing ttf_draw_glyph_cell()
rasterizer, independent of the box's own grid/cursor state. Border lines
are drawn after the glyph loop so an oversized cell can only be clipped
by them, never erase them.

console.c/console.h: console_fb_strip_draw() thin wrapper, matching the
existing console_fb_enable_ttf()/console_fb_scroll_*() pattern.

repl.c: builds a plain-text "[VMName] ok> <input>" mirror in
g_strip_prompt/strip_refresh(), refreshed on every keystroke (including
backspace) from sk_readline() -- already wired for item 4.4v, since
keyboard-typed characters will flow through the same console_getc() path
once that lands. Also widened sk_repl_step()/sk_repl_run()'s local input
buffer from a second, smaller 256-byte buffer to INPUT_BUFFER_SIZE
(1025), per 4.4w's decision.

Verified: three-arch clean QEMU boot + logs, amd64 screendump showing
the box and strip as two visually distinct regions with no visible
glyph/border clipping.

Punch list §25 item 4.4x complete.

Headers for LithosAnanke, the bare-metal UEFI kernel (src/starkernel/). Built only via Makefile.starkernel; gated by __STARKERNEL__ when shared with hosted code.

  • uefi.h — UEFI protocol/type definitions consumed by the loader.
  • elf64.h, elf_loader.h — ELF64 parsing and kernel-image loading.
  • boot_info_offsets.h — struct-offset constants shared between the assembly bootstrap and the C boot path.
  • arch.h, apic.h, timer.h — architecture init, APIC interrupt controller, timer (TSC/HPET/APIC, 100 Hz heartbeat).
  • console.h, framebuffer.h, vt100.h — UART 16550 console, framebuffer driver, and VT100 terminal emulation over the framebuffer.
  • pmm.h, vmm.h, kmalloc.h — physical memory manager (bitmap allocator), 4-level x86_64 paging, kernel heap allocator.
  • pci.h, virtio_blk.h — PCI enumeration and the VirtIO block device driver (disk backend for the kernel block subsystem).
  • capsule.h, capsule_birth.h, capsule_loader.h, capsule_run.h, capsule_vm_physics.h, capsule_generated.h — capsule system types, birth protocol, physics-runtime capsule bindings, and the build-time- generated capsule directory (see tools/mkcapsule.c).
  • kernel_args.h, cmdline.h — boot-time kernel argument parsing (starforth.cfg / command line).
  • repl.h — kernel REPL.
  • log.h, doe_log.h — kernel logging and DoE metrics logging.
  • q48_16.h — kernel-build copy of Q48.16 fixed-point arithmetic.
  • xxhash64.h — content-addressing hash used for capsule IDs.
  • hal_memory.h — hardware-abstraction-layer memory interface.

Subdirectories:

  • hal/ — top-level hardware-abstraction-layer interface.
  • vm/ — kernel VM subsystem headers (capsule arena, parity logging, bootstrap wiring).
  • freestanding/ — minimal libc-shim headers (assert.h, ctype.h, errno.h, inttypes.h, math.h, sched.h, signal.h, stdio.h, stdlib.h, string.h, time.h, sys/time.h, sys/types.h) for building shared VM code in the freestanding kernel environment, where no real libc is available.
