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.

src/starkernel/
LithosAnanke — the bare-metal UEFI kernel that boots StarForth directly on
hardware (amd64/aarch64/riscv64). Built only via Makefile.starkernel; the
only valid acceptance test is the three-arch QEMU boot (see
.claude/CLAUDE.md), never make test.
kernel_main.c— kernel entry point, driving the boot milestones (console init, PMM, VMM, interrupts, timers, kmalloc heap, VM bootstrap).repl.c— kernel REPL.doe_log.c— kernel-side DoE (Design of Experiments) metrics logging.
