  return `You are ADAPTING a proven byte-matched body onto a near-identical sibling function — Brave Fencer Musashi matching decomp (PS1, gcc-2.7.2 + maspsx). Repo: ${REPO}. This is an EDIT task, not a from-scratch crack.

TARGET: ${c.name} in ${c.binary} — ${c.nins} instructions${c.jr ? ' (mid-function jr / jump table)' : ''}. Asm truth: ${c.sub}/${c.name}.s
SEED (${(c.sim * 100).toFixed(1)}% skeleton-similar, already byte-matched as ${c.seed.name} in ${c.seed.binary}): ${seedWhere}

THE MEASURED DIFF — the target differs from the seed at exactly ${c.n_blocks} site(s), ${c.n_tokens} instruction(s) total (class ${c.klass}):
${diffBlock(c)}

METHOD:
1. Read the seed body. Copy it to ${REPO}/.run/${WAVE}/${c.name}/${c.name}.c as the definition of ${c.name}.
2. RENAME the symbol surface to the TARGET's own: every callee "func_XXXXXXXX", data "D_XXXXXXXX",
   and jump-table label must come FROM THE TARGET .s (${c.sub}/${c.name}.s) — the .s is the symbol
   ground truth. Do not keep the seed binary's symbols. Positional correspondence: the bodies align
   1:1 outside the diff blocks above.
3. Apply the minimal SEMANTIC edit the diff implies. An insert/delete of lui/ori/addiu is almost
   always a changed CONSTANT — decode the target's words above (lui hi16 + ori/addiu lo16) and use
   the TARGET's value in the C literal. An inserted load/store or branch token usually means one
   added or removed statement/condition. Make the smallest edit that explains the diff.
4. Iterate: cd ${REPO} && python3 tools/match_one.py ${c.name} --c .run/${WAVE}/${c.name}/${c.name}.c --asm-subdir ${c.sub}
5. On MATCH: sha1sum the draft, report it, STOP. If two honest attempts leave a residual, report
   NEAR with the exact remaining diff — NEAR is a resumable state, not a failure.

OUTPUT DISCIPLINE (a previous wave lost 21 verified drafts to a shared directory):
- Your ONLY output dir is ${REPO}/.run/${WAVE}/${c.name}/ — create it, work there.
- Final draft MUST be exactly ${REPO}/.run/${WAVE}/${c.name}/${c.name}.c
- NEVER delete, move or modify ANY file outside your own directory. Sibling agents are working in
  adjacent directories RIGHT NOW. Do NOT clean up at the end.
- Never write to src/, config/, include/ or any tracked file. No make. No git.

RULES: gcc-2.7.2 emits no "error:" prefix — read the raw compiler text. match_one MATCH is a
CANDIDATE (cookbook §52b) — state your integration surface in notes: which callees/globals you
declare and whether the host TU declares them differently (§161c). Match register allocation
exactly (G3). If the seed body is a DEFINE_ macro, expand it to a plain function definition in your
draft — do not emit a macro.`

${r.fn} (${c.binary}, ${c.nins} ins, ADAPTED from ${c.seed.name}) claimed MATCH at ${r.draft_path}; claimed sha1 ${r.sha1 || '(none)'}.

REFUTE it. Default confirmed=false. In this order:
1. "ls -l" and "sha1sum" the draft — it must EXIST.
2. Gate it yourself: cd ${REPO} && python3 tools/match_one.py ${r.fn} --c ${r.draft_path} --asm-subdir ${c.sub}
   ("FAIL: no C file" means the draft is MISSING — that is a refutation, never a pass.)
3. The draft must DEFINE ${r.fn} as a plain function (no INCLUDE_ASM, no macro emission, no inline
   asm standing in for compiled code), and its symbol surface must come from the TARGET .s, not the
   seed binary (spot-check two callee/data names against ${c.sub}/${r.fn}.s).
4. Re-run "sha1sum" LAST, after everything else, and report it as sha1_after. If the file vanished
   or changed since step 1, say so loudly.
Do NOT edit or delete anything. Report failures; do not fix them.`
