Plan 2026-10-20 (ENGINE step 4), Task A2, for #189. Captain Bob, 2026-11-13: "The ten"; "Accept it". - compile.f18 (COMPILE,): a word is copied in line only when it is flagged in-line and compile-only (24) -- the ten that work on the return stack, >R R> R@ I J LEAVE and the later UNLOOP 2>R 2R> 2R@. Every other word, in-line ones too, is a call the hook at `call` sees. - EXECUTE calls the xt: `call xt` (opcode 3, slot 0) and a ; in (EXEC), run. INTERPRET runs a word by (GO): `call xt` and `jump (IL)` in (RUNX), entered by a jump, at the old return-stack depth. - host_map.h: (EXEC) BUF0_W-22, (RUNX) BUF0_W-115, from what was free. - Its cost, accepted: one return entry at the bottom of a chain (30 deep from the prompt, not 31) and one per explicit EXECUTE while its word runs; the hosted boot +2.4% (2.917 s to 2.987 s), instructions +0.4%. - Tests first (logs/20261113-045122/a2): inline_words_are_called, residue_stays_inline, execute_passes_the_hook, rstack_kept_across_call, abandoned_definition_not_called -- 3 of 1096 failed before. The depth checks moved to the new figures; SEE shows the calls; two layout checks use in-line test words; 2>R 2R@ 2R> checked in test_host_quit. - DECOMPOSITION.md EXECUTE, the plan's A2 and rulings, FABRIC-3 XLVIII.22. Suite: test, test-32 99 programs 0 failures; v4-checks 79 under the sanitizers 0 failures, the hosted builds alike; hosted POST 539/539.

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.
