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>

with hosted code.

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.
