The boot is now nucleus, forth79.4th, POST, prompt, on both products. - forth79.4th: U* and U/MOD, the capsule's first colon definitions. They are in the FORTH-79 Required Word Set and neither v3 nor v4 had them. - post79.4th: 550 cases, 126 of the 130 required words. 443 are v3's with v3's result. The rest follow three rulings (2026-10-05): address- dependent cases are checked for count, not value; where v3 departs from FORTH-79 the standard's result is expected; words v3 has no case for get cases written by hand. v4/tools/post79_rules.py holds each exception with its reason and docs/v4.0.0/POST79.md lists them all. - every case starts from an empty stack, DECIMAL and FORTH DEFINITIONS - the boot requires POST's tally line with fail=0 Verified: tests=550 pass=550 fail=0 and identical PARITY lines on hosted amd64, aarch64 and riscv64 (make -C v4 hosted-check) and on bare metal, clean qemu with STARFORTH_V4=1, on the same three (logs/20261005-1619xx, -1621xx, -1625xx). A U/MOD broken on purpose fails five cases and stops the boot. make -C v4 test passes. Not shown: all words but those two are still assembled, so POST has so far tested the assembled words. Nothing was typed at a bare-metal prompt. Open: PAD 42 OVER ! faults on v4 (D-1). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
