Test support, beside the slot packer: reads definitions in the notation DECOMPOSITION.md uses -- words, opcodes, literals, constants, labels, branches, FOR NEXT and FOR UNEXT, in-line macros, comments -- and lays them down through the slot packer, so they no longer have to be retyped opcode by opcode in C. Tested by assembling SWAP, UM/MOD, C@ and C! both ways on two nodes and comparing memory word for word, by running what is assembled, and on every error it reports, each with its line number.

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.
