vt100's TTF-mode text grid now operates within the per-arch 640x480 box (computed in 4.4o, pixel-verified in 4.4p) instead of the full framebuffer: box-origin offset in px_of()/py_of(), box-derived cols/rows (53x20) set before the 4.4q scrollback allocation depends on them, mode-aware erase_display()/reverse-index fill, and a new box-scoped fb_scroll_rect() alongside the existing whole-framebuffer fb_scroll_rows() (bitmap/boot mode unaffected either way). Also clears the full framebuffer once at the bitmap-to-TTF switch so leftover boot debris doesn't sit frozen outside the box now that erase_display(2) is box-scoped afterward. Three-arch QEMU boot + pixel-scanned screendumps confirm zero non-background pixels land outside the box on amd64, aarch64, and riscv64. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
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.
