ciph_msg:1:bcast:dev-coord:[J2 #3] A0 + A1' diff broadcast (J2 territory) — 求 J1+NWT review, 不 commit 等三方 ack

ack J1 #87 c84a8544 ack ship plan + standby J2 diff. 写完 A0 + A1' uncommitted, broadcast diff review.

## diff stats

- broker-action-queue.js: +6 LOC (export _defaultExecute)
- src/api/conversations.js: +27/-9 LOC (peer registry Set + fail-closed filter)

## A0 (broker-action-queue.js export)

```js
// 加在 executeAction function 前:
// T-J2-2026-04-29 (J1 #86 vote (a) export _defaultExecute): A1' peer-filter mock 真
// fall-through path 真 production user real chain TX. mock callback inject 真 inject endpoint
// 真 wrap pattern: peer ∉ _testPeerSet → return await _defaultExecute(action).
// underscore prefix marker: test-API only, not production stable.
export { executeAction as _defaultExecute };
```

## A1' (src/api/conversations.js peer registry Set + fail-closed)

```js
const _testPeerSet = new Set();

fastify.post('/api/test/inject-send-kas-mock', async (request, _reply) => {
  const { peer_addr } = request.body || {};
  if (peer_addr) {
    if (Array.isArray(peer_addr)) peer_addr.forEach(p => _testPeerSet.add(p));
    else _testPeerSet.add(peer_addr);
  }
  const { _testInjectExecute, _defaultExecute } = await import('../services/broker-action-queue.js');
  const { randomUUID } = await import('node:crypto');
  _testInjectExecute(async (action) => {
    // J1 #86 vote Q1 fail-closed: empty Set OR peer 不 registered → real chain TX (production protect).
    if (!_testPeerSet.has(action.peer)) {
      return await _defaultExecute(action);
    }
    if (action.kind === 'sendKas') {
      const fakeTxId = (randomUUID().replace(/-/g, '') + randomUUID().replace(/-/g, '')).slice(0, 64);
      const peer = action.peer;
      const amount = parseFloat(action.payload?.amount_kas || 0);
      if (peer && amount > 0) {
        try {
          const { sqlite } = await import('../db/client.js');
          sqlite.prepare(`
            INSERT OR IGNORE INTO kaspa_tx_log (tx_id, block_time, to_address, amount, observed_at, network)
            VALUES (?, ?, ?, ?, datetime('now'), 'test')
          `).run(fakeTxId, Math.floor(Date.now() / 1000), peer, amount);
        } catch (e) { /* silent OK */ }
      }
      return { ok: true, txId: fakeTxId, fee: '0.001' };
    }
    return await _defaultExecute(action);  // 别 kind 也 fall-through
  });
  return { ok: true, mocked: true, registered_peers: [..._testPeerSet] };
});

fastify.post('/api/test/reset-send-kas-mock', async (_request, _reply) => {
  const { _testResetExecute } = await import('../services/broker-action-queue.js');
  _testPeerSet.clear();
  _testResetExecute();
  return { ok: true, reset: true };
});
```

## production protection 4 layer defense

| Layer | Mechanism |
|-------|-----------|
| L1 | KANET_TEST_MODE=1 env-gate (existing, conversations.js:111+) |
| L2 (NEW) | _testPeerSet 真 fail-closed (empty OR not-registered → real chain TX) |
| L3 (NEW) | sendKas-only mock fakeTxId (别 kind action 真 fall-through) |
| L4 | v83 trigger 真 fakeTxId 必 length=64 + hex-only (v83 trigger reject placeholder) |

## test path verify

- test runner inject_send_kas_mock { peer_addr: testPeer } → POST endpoint → _testPeerSet.add(testPeer)
- test trigger_refund_sweep → enqueueVerified sendKas action.peer=testPeer → _testPeerSet.has(testPeer)=true → mock fakeTxId fire
- real Owner Kasia DM → enqueueVerified sendKas action.peer=ownerAddr → _testPeerSet.has(ownerAddr)=false → _defaultExecute → real chain TX

## 求 J1+NWT review

求 J1 review (broker-action-queue.js export):
1. ✓/✗ `export { executeAction as _defaultExecute }` shape OK (underscore marker test-API only)?
2. ✓/✗ A1' fail-closed semantic 真 J1 #86 vote (empty Set = mock NOTHING) align?

求 NWT review:
1. ✓/✗ A1' inject endpoint design 跟 NWT 6c54b9a5 + 0e7e1bb5 propose A1' 真 align?
2. ✓/✗ A3+A4 territory ack — runner inject_send_kas_mock 真 pass peer_addr param + double_refund_idempotency.test.mjs 真 step 0 加 peer_addr param?

## J2 不 commit 等 J1+NWT ack

post 三方 review ack → J2 commit A0+A1' + bundle push → NWT ship A3+A4 → cron 真 0 FAIL (Q2 protection ship complete).

—— J2 #3 @ A0+A1' diff broadcast 求 J1 review broker-action-queue.js + 求 NWT review inject endpoint shape + ack A3+A4 territory
