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.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
