⚡ A PREVIOUS AGENT ALREADY ATTEMPTED THIS FUNCTION. Read its notes FIRST — they contain the body
shape, the idioms it proved load-bearing, and the EXACT residual it could not close:
  cd ${REPO} && python3 -c "import json;print(json.load(open('.run/jr48/prior_notes.json'))['${t.name}'])"
Treat it as a strong prior from a peer, NOT as gospel: its claims about what is load-bearing are
reconstructions. If a note contradicts what you measure, the measurement wins — and say so. Two
wave-5 agents found their predecessor's file/line citations WRONG while its idioms were RIGHT —
re-derive the destination TU yourself rather than trusting quoted line numbers.

IF THE PRIOR ATTEMPT WAS GATE-REFUSED (standalone MATCH, whole-binary gate said DIFF), the residual
is almost certainly IN-TU, so prove it in situ before you claim MATCH:
  copy the destination TU to your own dir, splice your body over its INCLUDE_ASM, run the pinned
  triple end-to-end (cpp -> cc1 -O2 -> maspsx --aspsx-version=2.56 --expand-div -> as), objdump your
  function out of the WHOLE-TU object and masked-diff it against the splat .s.
  Two gotchas that cost a wave-5 agent real time: the wrong --aspsx-version yields ~32 spurious
  mismatches ALL of the ori-vs-addiu li-form shape (that uniform shape is the fingerprint of a
  version mismatch, NOT a codegen residual); and "../shared/engine_core.h" resolves relative to the
  including file, so put the spliced TU one directory DEEP with a "shared" symlink beside it.
` : ''
  return `You are cracking ONE function for the Brave Fencer Musashi matching decompilation (PS1, gcc-2.7.2 + maspsx). Repo: ${REPO}.

TARGET: ${t.name} in ${t.binary} — ${t.nins} instructions, family reach ×${t.reach}${t.jr ? ' (mid-function jr / jump table)' : ''}.
Splat asm subdir: ${t.sub}. Asm file: ${t.sub}/${t.name}.s
${priorBlock}
WHY IT MATTERS: zero-crack sibling family — this ONE exemplar templates to ${t.reach - 1} more binaries mechanically.

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

METHOD:
1. STEP 0 — §160g callee-set sibling search (mandatory). Extract the callee set + magic literals from
   the .s, grep already-matched C in src/ for the same shape. Highest-value hits are IN THE
   DESTINATION TU ITSELF — an already-matched caller often gives the exact signature, and the host TU
   fixes every symbol type for free. Read the destination TU before any cross-overlay grep.
2. A Ghidra seed may exist at .run/ghidra_c/${t.name}.c — VERIFY it is for THIS address before trusting it.
3. Cookbook — READ THESE FOUR BLOCKS, they are this campaign's own harvest and the most relevant
   knowledge in the file (~100 entries banked over the last four waves):
     §160a/b/c and §161a/b/c — the base idioms.
     §162 — jump-table MAXVAL mirror ("check BOTH edges"), temp SCOPE as a live-range lever, the
       LICM movable/preheader-order laws, non-void return visible in delay slots, cross-jump
       DIRECTION as a source-shape oracle, the unreferenced-local frame oracle, and defeating
       local-alloc's optimize_reg_copy_1 with an in-place shift — a class where REGISTER PINS
       PROVABLY CANNOT HELP.
     §163a-e — decl-conflict severity is SCOPE-DEPENDENT (block scope is a conflict SOLVENT); the
       switch-index parameter-WIDTH oracle (sll/sra straddling the minval subtract);
       case_values_threshold is 5 (an empty case glued to default can be the only thing that emits a
       table); cse deleting a copy by rewriting the PREVIOUS insn's SET_DEST (§162j's symptom in a
       DIFFERENT pass); the frame as a PSEUDO-NUMBER oracle.
     §164-01..82 and §165-01..47 — 129 further laws, each vetted by an independent skeptic and
       carrying its evidence grade. **§164z and §165z list 48 REFUTED claims between them — read
       them before spending time on a mechanism, so you do not re-derive something disproved.**
       Note §165-01 BOUNDS §163a: a "conflicting types" diagnostic means block scope IS a solvent
       (move the typedef AND the extern into the block); "too many arguments" means no declaration
       spelling at any scope helps — cast the call site (§17a-1/§161c).
   Search these before inventing a mechanism: of 190 laws the last waves claimed as new, 57% were
   already here or did not survive scrutiny.
4. Iterate: cd ${REPO} && python3 tools/match_one.py ${t.name} --c .run/${WAVE}/${t.name}/${t.name}.c --asm-subdir ${t.sub}
5. On MATCH: run sha1sum on the draft, report it, and STOP.

RULES: gcc-2.7.2 emits no \`error:\` prefix — read the raw compiler text; "no diagnostic" never means
"compiler wall". match_one MATCH is a CANDIDATE (§52b) — state your integration surface: which
callees/globals you declare and whether the host TU declares them differently (§161c). A block-scope
decl that CONFLICTS with a visible file-scope one is a gate failure; one that AGREES is free — and
you cannot simply drop the decl, because match_one compiles standalone. Report NEAR honestly with the
exact residual. Match register allocation exactly (G3).`
}

function verifyPrompt(c, t) {
  return `ADVERSARIAL verification, Brave Fencer Musashi decomp. Repo: ${REPO}.

${c.fn} (${t.binary}, ${t.nins} ins) claimed MATCH at ${c.draft_path}; claimed sha1 ${c.sha1 || '(none)'}.

REFUTE it. Default confirmed=false. In this order:
1. \`ls -l ${c.draft_path}\` and \`sha1sum ${c.draft_path}\` — it must EXIST.
2. Gate it yourself: cd ${REPO} && python3 tools/match_one.py ${c.fn} --c ${c.draft_path} --asm-subdir ${t.sub}
   ("FAIL: no C file for <fn>" means the draft is MISSING — that is a refutation, never a pass.)
3. The draft must DEFINE ${c.fn} (not a renamed/stub body), with no INCLUDE_ASM, no #include of a
   nonexistent path, no hand-written inline asm standing in for compiled code.
4. Re-run \`sha1sum ${c.draft_path}\` LAST, after everything else, and report it as sha1_after. If the
   file vanished or its hash changed since step 1, say so loudly — a previous wave lost 21 verified
   drafts to exactly that and nothing detected it.
Do NOT edit or delete anything. Report failures; do not fix them.`
