First code for StarForth v4 (JUSTIFICATION.md section 10, step 1): one node of the 32-instruction core as a C99 model, with cell width as a build parameter. - Node: P, A, B, F18 circular stacks (10 and 9 deep, D-2), word-addressed memory (D-1), 5% guard bands on every bounded list. - Instruction word: six 5-bit slots in 32 bits at every cell width. - Executor: all 32 opcodes of DECOMPOSITION.md 1.3. Cell arithmetic wraps explicitly; no signed overflow or implementation-defined shift. - Heat: per-opcode and per-call-target counters and the anti-clock, driven by instruction retirement (1.4, D-6 interim). - Slot packer and runner for tests, and a reference unsigned multiply in plain C99 with no 128-bit type. Tests run at 32- and 64-bit cells, and under ASan and UBSan. They cover every opcode and execute the first section 4 definitions (NIP SWAP OR NEGATE ROT 0< 0= 2DUP - U<) against the C operation each stands for. UM* as written in section 4 is exact only while u1 <= 2^(n-2). Two known failing cases are pinned in test_foundation.c until it is rewritten. DECOMPOSITION.md: record D-9, the instruction word is 32 bits at every cell width (ruled 2026-10-02). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
