rajamesandClaude Opus 5.5 a1afb44598 feat(v4.0.0): the editor, redone in FORTH; COLD WARM PAGE VERSION DEFER
- capsule/editor.fth: the block editor as FORTH source, which the node
  compiles itself.  It is a vocabulary, EDITOR, used at the ordinary
  prompt: n EDIT, then L N B T P E D S H R I WIPE DONE.  v3's EDIT, a
  shell of its own, is not carried over (ruled 2026-10-05); v3's L S and
  SHOW are kept in FORTH as they were, with COPY.
- system.v4: COLD (the system as the loader left it), WARM, PAGE,
  VERSION, 79-STANDARD (FORTH-79: silent), and DEFER IS DEFER@ as v3.
- input.v4: where words are split at blanks a zero byte reads as a blank,
  so a block never written, or filled a line at a time, loads cleanly.
- tests/test_host_quit.c: the editor's source fed to the prompt line by
  line, every command on empty and full screens, what reaches storage;
  the system words; deferred words.

v4/

StarForth v4: the 32-instruction F18-derived core. The design lives in docs/v4.0.0/JUSTIFICATION.md (why) and docs/v4.0.0/DECOMPOSITION.md (every v3 word mapped to a v4 fate).

The first deliverable is the hosted C99 golden model (JUSTIFICATION.md §10, step 1). It must pass POST and hold K≡1.0 with 32- and 64-bit cells on all three host ISAs.

Acceptance (JUSTIFICATION.md §16): v4 must be equivalent to v3 at any point in time, with the same vocabularies and behaviour, on the F18-derived engine; and every ISA, hosted and bare metal, must still reach its ok prompt. make -C v4 test passing is a development check, not acceptance.

What exists so far is the single node: registers, circular stacks, memory, all 32 opcodes, per-opcode and per-call-target heat, and three console registers (CONSOLE-TX, which captures output, and CONSOLE-RX and CONSOLE-STATUS, which hand out input a test feeds) standing in for the console node until the mesh exists. The tests load definitions onto a node either opcode by opcode (v4/include/v4/asm.h) or as text in the notation DECOMPOSITION.md uses (v4/include/v4/text.h). make -C v4 test builds and runs the tests at both cell widths; make -C v4 sanitize repeats them under ASan and UBSan. There is no compiler capsule, no POST and no K measurement yet.
