func_801EDC18 (md_SC05_023) is the largest multiplier remaining — 57 members. The wave agent
abandoned it at "closeness 6" with class SIZE-MISMATCH [redraft]. It was two lines from correct.
THE CODE (cookbook §160a): the target copies 8 bytes with lwl/lwr + swl/swr — gcc-2.7.2's
emit_block_move for a type with ALIGNMENT 1. The draft used a u32 copy (aligned lw/sw), which is
wrong by construction. `typedef struct { char c[8]; } Blk8; buffer = D_801ED98C;` reproduces it.
Six spellings were tried in parallel; two independent agents converged on the same one.
THE INSTRUMENT (§160b) — this is the part worth more than the function. The target .s bundles a
leading `.section .rodata` block (D_801ED98C as two .word) ahead of .text. Those lines carry the
same `/* off vaddr HEX */` shape as instructions, so masked_diff.insns_from_s counted them as TARGET
instructions, while insns_from_object (objdump -j .text) can never emit them. A byte-perfect draft
therefore read `mine=26, target=28, 26 mismatched` — every position shifted by a constant +2 — and
got classified as needing a redraft. 116 of 12,583 .s files in the corpus have this shape, one at
-29 instructions. Every one of them would report a false wall to any agent that tried it.
Fixed: insns_from_s tracks .section and counts only .text. Full-corpus control: 12,467 unchanged,
116 corrected, 0 regressions. Same artifact class as §129a (post-carve jtbl inflation).
THE OWNERSHIP LAW (§160c) — my own error, corrected by the gate. Four sites declare
`extern short D_801ED98C;` and nothing in src/ defines it, so I shipped an extern-only draft. The
gate refuted it: `undefined reference`. The .s block the draft REPLACED was the definition. The
variant emitting `const Blk8 D_801ED98C = {{...}}` banks clean. Never infer ownership from externs.
R22 clean-fleet: check-all 213 passed / 0 failed of 213.
ALSO BANKED — the wave's idiom harvest, which had been sitting unwritten in workflow transcripts
(R16/R30 debt): §160d the ASYMMETRIC INDEX RELOAD (a just-stored narrow field read twice emits
reuse-then-reload; the C is deliberately asymmetric), §160e a stack-layout scheduling rule now
byte-proven on a SECOND independent function (promoting it from coincidence to rule), §160f the
address-only global store via array decl, §160g sibling-search keyed on the CALLEE SET as step 0 of
every wave prompt (one grep turned a 126-instruction crack into a copy-edit).
Cookbook index regenerated: 468 sections.
