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.

# A2 (plan 2026-10-20; #189), 2026-11-13 test_host_compile-before.log: A2's five tests against the compiler before the change: 3 of 1096 fail (no call seen for DUP and +; EXECUTE not seen, in a definition or at the prompt); the other two pin what must not change. test-test32.log: make -C v4 test test-32 after: 99 programs, 3724180 checks, 0 failures. ../v4-checks: scripts/nightly.sh v4-checks after: 79 programs under the sanitizers, 0 failures; the hosted builds alike. timing.txt: the hosted amd64 boot (POST 539), five runs each, alternating: OLD = bacb7b06, NEW = A2. Median 2.917 s / 2.987 s (+2.4%); instructions 59302047 / 59537530 (+0.4%).
