// ⚠ TEMPLATE-LITERAL MINEFIELD: prompts are backtick strings — a markdown backtick or literal
// dollar-brace in prose kills the workflow at parse time. Use "double quotes" for inline code.
//
// Cards: tools/family_cousins.py --aprop-cards -> .run/aprop_cards.json, chunked into batches by
// the orchestrator. A batch = {family, nins, seed{...}, members:[{name,binary,addr,sub,n_sites}], idx}
// Each agent reads its OWN full card (with every member's word sites) from the cards file — the
// orchestrator never inlines them.
//
// WHY THIS WAVE EXISTS (S49): these members share their family's h_seq with an ALREADY-MATCHED
// sibling, so the mnemonic streams are identical by construction and the mechanical remap still
// refuses them (unresolved immediates / register drift): the >=16-reach head swept 0/245 banked
// with 188 refused. The differences are WORDS — a struct offset, a data symbol, a register — and a
// median member differs in TWO of them. That is an edit, and it is why one agent takes a whole batch.

  return `You are re-emitting ONE proven function body for ${b.members.length} sibling copies — Brave Fencer Musashi matching decomp (PS1, gcc-2.7.2 + maspsx). Repo: ${REPO}. This is a SUBSTITUTION task, not a decompile.

THE FAMILY: ${b.family} — ${b.nins} instructions, ${b.reach} open copies fleet-wide, class ${b.cls}${b.jr ? ' (mid-function jr / jump table)' : ''}.
THE PROVEN BODY: ${b.seed.name} in ${b.seed.binary} — ${b.seed.kind === 'macro'
    ? 'the DEFINE_' + b.seed.name + '() macro in ' + b.seed.path
    : 'the plain definition in ' + b.seed.path}. It is byte-matched. Do not redesign it.

EVERY sibling below has the SAME instruction skeleton as that body. They differ only in WORDS —
a struct offset, a data-symbol address, sometimes a register. Your card lists the exact differing
word positions for each sibling, both sides disassembled. PRINT YOUR CARD FIRST:
  cd ${REPO} && python3 -c "import json;c=json.load(open('${CARDS}'))[${b.idx}];print(c['seed']);[print(m['name'],m['binary'],m['n_sites'],m['sites']) for m in c['members']]"

SIBLINGS IN YOUR BATCH:
${list}

METHOD:
1. Read the proven body. Work out the PARAMETERIZATION: which C expressions produce the differing
   words. A changed "lbu \$v0, 0xC1(\$a0)" -> "lbu \$v0, 0x1A0(\$a0)" is a struct FIELD OFFSET in the
   source; a changed "lw \$v0, 0x6EAC(\$at)" -> "0x115C" is a DIFFERENT GLOBAL (a different D_ symbol).
   A changed register is regalloc drift — usually a different local's live range, occasionally a
   different variable order.
2. For EACH sibling: write ${REPO}/.run/${WAVE}/<FN>/<FN>.c defining that sibling, with the symbol
   surface taken from ITS OWN .s (callees, D_ globals, jump-table labels — the .s is ground truth,
   never the seed's symbols) and the offsets/constants its card specifies.
3. Verify each: cd ${REPO} && python3 tools/match_one.py <FN> --c .run/${WAVE}/<FN>/<FN>.c --asm-subdir <ITS SUB>
4. Report every sibling you attempted with its own verdict and sha1. A sibling you could not close
   is NEAR with its exact residual — that is useful, not a failure. Do not skip siblings silently:
   the batch is judged on coverage as well as matches.

OUTPUT DISCIPLINE (a previous wave lost 21 verified drafts to a shared directory):
- One directory per sibling: ${REPO}/.run/${WAVE}/<FN>/ — create it, work there.
- NEVER delete, move or modify ANY file outside your own directories. Sibling agents are working in
  adjacent directories RIGHT NOW. Do NOT clean up.
- NEVER write to src/, config/, include/ or any tracked file — not even a typedef, not even a
  header. An agent did that last wave and blocked the whole gate. 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. Match register allocation
exactly (G3). If the proven body is a DEFINE_ macro, expand it to a plain function definition in
each draft — do not emit a macro.`

${d.fn} (${m.binary || '?'}, family ${b.family}) claimed MATCH at ${d.draft_path}; claimed sha1 ${d.sha1 || '(none)'}.

REFUTE it. Default confirmed=false.
1. "ls -l" and "sha1sum" the draft — it must EXIST.
2. Gate it: cd ${REPO} && python3 tools/match_one.py ${d.fn} --c ${d.draft_path} --asm-subdir ${m.sub || ''}
   ("FAIL: no C file" means the draft is MISSING — a refutation, never a pass.)
3. It must DEFINE ${d.fn} as a plain function — no INCLUDE_ASM, no macro emission, no inline asm
   standing in for compiled code — and its symbols must come from ITS OWN .s, not the seed binary's
   (spot-check two names against ${m.sub || ''}/${d.fn}.s).
4. Re-run "sha1sum" LAST and report it as sha1_after; say so loudly if it changed or vanished.
Do NOT edit or delete anything. Report failures; do not fix them.`
