Punch list §25 item 4.3.7f complete. No code changes -- ttf.c/ttf.h/ ttf_words.c unchanged since 4.3.7e; this is verification only, same posture as 4.3.6g. Three-arch acceptance boot clean (standard make ARCH=<arch> clean qemu, run in order, one at a time): all three reached [Hera] ok> cleanly, logs committed under logs/20260810-231553(amd64)/231640(aarch64)/ 231739(riscv64). One screendump per architecture, identical TTF-TEXT command sequence (S" Hi 4.3.7e!" 200 200 28 16777215 TTF-TEXT) via monitor-socket + serial-injection, same pattern as 4.3.7c/e. All three show the string rendered legibly with correct mixed-case/digit/punctuation glyphs and identical monospace spacing. TrueType rendering (4.3.7-4.3.7f) is now complete, adjunct to the stroke font per §27.7 decision #4. Stopping here before scoping REPL wiring (M8), per this item's own posture matching 4.3.6g.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
