FILL ERASE MOVE, COUNT CMOVE CMOVE> BLANK -TRAILING COMPARE SEARCH SCAN
SKIP, as loops over the call-free C@ and C!, executed on the golden
model at both cell widths against C and five recorded transcripts of
the v3 binary.

A negative count reads as 0 where v3 read it so, and elsewhere writes
nothing and sets NODE-ERROR.  v3's counted-string auto-detection is not
kept in any of them.

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 a console capture register (CONSOLE-TX) standing in for the console node until the mesh exists. 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.
