From dd6c393a897fb09bb9656a00942f24e63c3707ec Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 13 Nov 2026 00:50:56 +0000 Subject: [PATCH] feat(v4): HEAT-OP[0..31] and ANTICLOCK, read by HEAT-OP@ and ANTICLOCK@ #189 -- Captain Bob, 2026-11-12: "Add HEAT-OP. If it's a huge performance hit, we'll revert it. If not ... it stands"; a full 33-cell array, as DECOMPOSITION.md section 7 draws it; the Stadium feed is Phase 1's. - node.h/node.c: v4_node_heat_regs_attach; a data fetch from base+k gives opcode k's count, base+32 the anti-clock (the low cell at 32 bits); a store changes nothing. Reset detaches them. - host_map.h: HEAT_REG at word 13824, in what was free between the dictionary space and SEND_TEXT; the compile-time check covers it. Nothing moved. map-*.f18: HEAT-OP 13824, ANTICLOCK 13856. - image.h/image.c/mkmap.c: the image carries the address; v4_image_born attaches the node's own counts. - system.f18: HEAT-OP@ ( op -- n ), op mod 32; ANTICLOCK@ ( -- n ). word_count 318 -> 320 (hosted 317 -> 319): dict_hash changes. - v4-dictionary.tsv: both words; DECOMPOSITION.md 7 records the build. Also in this batch: - Makefile: make init installs qemu-user -- hosted-check needs it (Captain Bob: "Add to make init now"). - .claude/memory/rules.md, rule 5: stop and ask when something comes up (Captain Bob: "you are supposed to stop and ask"). Tests first (logs/20261113-005047/heat-op): test_node did not compile; test_host_quit 3 of 1337 failed. Suite: 199 programs, 7448554 checks, 0 failures; hosted-check, the three alike. Timing: no measurable cost.
