Punch list §25 item 4.3.7e complete. New src/word_source/ttf_words.c registers TTF-TEXT ( c-addr u x y size color -- ): lazily loads the v1 default font capsule + raster cache once, decodes UTF-8 (C reimplementation mirroring capsules/fabric.4th's DECODE-UTF8 exactly), looks up each glyph's cached bitmap, blits via fb_put_pixel, advances the pen by the glyph's real hmtx advance width scaled to pixels. Necessary plumbing: ttf_parse() now also locates hhea/hmtx, and ttf_glyph_advance_width() reads a glyph's advance width -- required for this item's own "proportional spacing correct" acceptance clause, no advance-width data existed anywhere else in the parser. Verified in tools/ttftest.c: A/a/0/space all read advance_width=600, correctly uniform since JetBrainsMono-Regular.ttf is monospace. (x,y) is raster pixel space (top-left origin, Y-down), deliberately not the stroke font TEXT's Cartesian Y-up convention -- recorded explicitly in ttf_words.h, not conflated. Verified live, amd64, screendump: injected S" Hi 4.3.7e!" 200 200 28 16777215 TTF-TEXT over a serial socket after boot, no error, captured a screendump showing the string rendered legibly with correct mixed-case/digit/punctuation glyphs and even spacing. TTF-TEXT is this item's permanent deliverable, not a throwaway probe. Compile-checked clean on all three architectures. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Hosted StarForth VM implementation (compiled by the root Makefile).
Bare-metal kernel sources live in src/starkernel/; FORTH word
implementations in src/word_source/; the test harness in
src/test_runner/; platform shims in src/platform/.
Entry point / interpreter core
main.c— CLI entry point, VM init, DoE mode dispatch.vm.c— interpreter loop, stacks, dictionary state (the central runtime file).vm_api.c— external VM API implementation.vm_bootstrap.c— VM bootstrap initialization.vm_debug.c— debugging utilities.vm_time.c— time-related VM operations.vm_internal.h— internal-only declarations shared across thevm_*.cfiles, not part of the publicinclude/vm_api.hsurface.repl.c— REPL read-eval-print loop.cli.c— CLI argument parsing.io.c— I/O operations.log.c— logging infrastructure.
Memory / dictionary / blocks
memory_management.c— dictionary allocator.dictionary_management.c— dictionary allocation and search.dictionary_heat_optimization.c— Loop #1 execution-heat tracking.word_registry.c— word registration system.block_subsystem.c— logical→physical block mapper.blkio_file.c,blkio_ram.c,blkio_factory.c— block I/O backends (file-backed, RAM-backed) and the factory that selects between them.stack_management.c— stack operations.
Physics-driven adaptive runtime (7 feedback loops)
physics_runtime.c— main physics coordinator.physics_hotwords_cache.c— Loop #1 hot-words caching.physics_metadata.c— per-word metadata tracking.physics_pipelining_metrics.c— Loop #4 word-transition prediction.physics_execution_hooks.c— execution instrumentation.rolling_window_of_truth.c— Loop #2 circular execution-history buffer.inference_engine.c— Loops #5/#6, statistical inference (window-width, decay-slope).ssm_jacquard.c— L8 Jacquard steady-state mode selector; consumescompudynamics.cfor tuning-word/config lookups.compudynamics.c— generic compudynamics module (cd_tuning_word(),cd_tuning_vm()); the score/UCB/reward/weight constants for the L8 adaptive table live here, not inssm_jacquard.c.heartbeat_export.c— heartbeat metrics export (CSV export function itself not yet implemented — seedocs/working/architecture/heartbeat_csv_export.md).
Math / measurement
math_portable.c— portable math functions.profiler.c— performance profiling.doe_metrics.c— Design of Experiments metrics (2^7 factorial).
Any .bak file alongside a .c file here (doe_metrics.c.bak,
inference_engine.c.bak, vm.c.bak) is a pre-edit backup left by a past
maintenance script (see scripts/remove_loop_conditionals.sh), not a
build input.
