ENGINE step 4 Phase 2 (plan docs/v4.0.0/plans/2026-11-13-engine-step4-phase2-word-accounts.md). Rulings,
Captain Bob 2026-11-13: "ID field in the header"; "Per heartbeat tick"; the ACL "All of it in Phase 4".
- The word ID, at xt-4 before the flags (ENGINE.md 3b). The system's words are numbered as they are
assembled, by a new directive, #id, (and #ids, the count), in the C assembler (text.c) and in the
machine ROM's (capsules/v4/rom), which counts in the system's own (NEXT-ID). (HEADER) numbers later
words; FORGET gives back the IDs it frees, always the newest; COLD resets to (BOOT-ID); (SEAL) records
it. All 313 system headers carry the cell.
- The kernel's records (v4/mesh.h): (TELL-DEFINED) and (TELL-FORGOTTEN), requests -19/-20 on port 0,
which the kernel puts in (WORD-DEFINED)/(WORD-FORGOTTEN) when it seals a node, and reads the system's
own words once. A bit per address marks a word's xt (calls into the ROM or headerless code are not
words); at call, the bit test and a count. v4_mesh_charge hands the owner the calls since.
- The Stadium: stadium_words_charge -- N calls as N of stadium_word_dispatch's dispatches, shared by calls
when the reservoir is short; sk_v4.c charges every node's words at the tick beside its opcodes, and
stadium_word_forget before an ID is used again.
- Tests first: test_text.c, test_host_dict.c, test_host_quit.c (numbering, FORGET, COLD),
test_mesh_boot.c (44 checks), kernel/tests/test_stadium_words.c; qemu_session.py: Hera's words
admitted after POST.
- amd64: Stadium words: promotions=141 after POST, CONSERVED; POST 539/539; word_count=377;
dict_hash 0xa854ba15b437d288 (the new cell); the boot 142 s against Phase 1's 153 s.
- v4 test, test-32: all pass; v4-checks: 80 programs under the sanitizers, 0 failures; the hosted
builds alike. docs/reference/v4-dictionary.tsv: the two new words; FABRIC-3 XLVIII.24.

word.f18: (NEXT-TOKEN) reads the console or a macro being expanded; labels,
branches by name (a label of the word, or a word, now or later), the
table of branches waiting, end of word, FOR/NEXT/UNEXT, macros, &NAME,
CONST+N, and (ONE), which dispatches a token. A forward branch to a name
not yet defined waits on a placeholder symbol, filled in by (DEFINE).
dir.f18: constant set here #, ", store, and start, which resolves, clears
the tables the ROM used and runs the word it names. main.f18: the ROM
itself, entry 12; on an error it stops at (ROM-FAILED) with the code and
line in its state, for the loader to report. sym.f18 generalized: any
counted string, placeholders, a hash of only a name's own cells.
test_host_rom_asm.c gives test_text.c's own texts (accepted and refused),
its four real definitions and the ROM's directives to text.c and to the
ROM: the same words, the same errors on the same lines, at both widths.
The ROM is 2036 words.

(FIND) ( -- rec | 0 ), (DEFINE) ( value kind -- ) and (OPCODE) ( -- op | -1 ),
entries 3-5. Names are refused as text.c's define refuses them, compared
case by case with text.c; a set variable may be set again. 256 hash heads,
records growing up and names growing down in dictionary space, used only
while the ROM assembles. text.c gains the data directives #, and ", (the
ROM's language; its mnemonic and reserved-word tables are data); the
nucleus image is byte-identical.
