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.

include/
Public headers for the hosted StarForth VM (src/). Kernel-only headers
live under include/starkernel/.
Core VM
vm.h— theVMstruct and all core types (DictEntry,DictPhysics, stacks, dictionary state); the central header most other files include.vm_api.h— external VM API surface.vm_host.h,vm_debug.h,startup.h,version.h— host integration, debug utilities, startup sequencing, version string.cli.h,repl.h,io.h,log.h— CLI parsing, REPL loop, I/O, logging.word_registry.h— word registration system shared by everysrc/word_source/*.cfile.compudynamics.h— the generic compudynamics module: tuning-word/config lookups (cd_tuning_word(),cd_tuning_vm()) consumed byssm_jacquard.c.
Memory / blocks
memory_management.h,dictionary_management.h— dictionary allocator and search.block_subsystem.h,blkcfg.h,blkio.h,blkio_factory.h— logical→ physical block mapper and pluggable block I/O backends (file/RAM).platform_alloc.h,platform_lock.h,platform_time.h— platform abstraction shims (hosted vs. kernel allocation/locking/timing).
Physics-driven adaptive runtime (7 feedback loops)
physics_runtime.h— main physics coordinator.physics_hotwords_cache.h— Loop #1, execution-heat hot-words cache.physics_metadata.h— per-wordDictPhysicsmetadata tracking.physics_pipelining_metrics.h— Loop #4, word-transition prediction.physics_execution_hooks.h— execution instrumentation hook points.rolling_window_of_truth.h,rolling_window_knobs.h— Loop #2 circular execution-history buffer and its tuning knobs.inference_engine.h— Loops #5/#6, window-width and decay-slope statistical inference.dictionary_heat_optimization.h— Loop #1 heat counters.ssm_jacquard.h— L8 Jacquard steady-state mode selector.doe_metrics.h— Design of Experiments (2^7 factorial) metrics.profiler.h— performance profiling hooks.
Arithmetic / codegen
q48_16.h— Q48.16 deterministic fixed-point arithmetic (used instead of IEEE-754 float specifically to keep cross-architecture behavior bit-identical).math_portable.h— portable math helpers.arch_detect.h,starforth_config.h— architecture detection and the build-flag fallback-default layer (used when a.cfile is compiled by hand withoutmake).vm_asm_opt.h,vm_asm_opt_arm64.h,vm_asm_opt_riscv64.h,vm_inner_interp_asm.h,vm_inner_interp_arm64.h,vm_inner_interp_riscv64.h— per-architecture assembler-optimized inner interpreter (USE_ASM_OPT=1).
