## 766c2c3f4 audit (8 dimensions)

| dim | finding | verdict |
|---|---|---|
| LOC | +37/-0 under 40 budget | ✓ |
| Path 决断 (a/b/c) per KI-3 | implementer authoritative path (b) Skill-instance poll, rationale clear (path a/c risk 高) | ✓ |
| Skill-instance limitation 真 acknowledged | matcher fires per DM NOT timer, server handlers do heavy lifting, defer Phase 3 server reactor | ✓ honest |
| 0 own state | per §9.5 #1 source test verified | ✓ |
| HTTP-only KI-4 | fetchJson via consoleUrl, 0 sqlite import | ✓ |

| Tests | 44/44 pass (41 prior + 3 T3.2 new: fail-closed / fetch-err / 0 own state) | ✓ |
| 戒"真"字 | 0 hit | ✓ |

## verdict: PASS clean ✓

## 关键 architectural insight (J2 commit msg + NWT 审 后 sediment 候选)

J2 explicit acknowledged Skill-instance limitation — matcher per DM NOT cron tick:
- Stage 4 settlement 大部分由 `trade-protocol-filter.handleExchangePaid` (server-side) 已 cover
- matcher reactor role = **T3.5 user-facing 反馈 layer** + **T3.3 emit hook input source**
- NOT replace server handlers (避免 dual-write race)

= broker 真 Stage 4 ship 实际 scope smaller than v1.0 spec assumed:
- T3.2 reactor (snapshot fetch) ✓
- T3.5 反馈 user (matcher per DM 反馈) ← 真 missing UX piece
- T3.3 specific emit gaps (if any) ← TBD per T3.0/T3.6 真 audit
- T3.4 deriveProtocolStatus (read-only consistency, NOT replace writers) ✓ per v1.1 决 (c)

KI candidate: **Skill-instance reactor scope limitation** — Skill 跟 cron tick 不同, server-side handler already 做 heavy lifting, Skill role = augment NOT replace。 Phase 3 sediment 候选: server-side independent reactor (cron tick) for non-DM-triggered events。

## green-light T3.3 — emitChainProtocol via Relay send-command (~40 LOC)

per task v1.1 §T3.3 (post 决断 1 修):

```js
async emitChainProtocol(eventType, payloadObj) {
  const consoleUrl = this._config?.consoleUrl || 'http://127.0.0.1:3100';
  const relayNodeId = this._config?.relayNodeId;
  if (!relayNodeId) throw new Error('emitChainProtocol: relayNodeId missing');
  const message = JSON.stringify({ t: eventType, ...payloadObj });
  return await fetchJson(`${consoleUrl}/api/relay/${relayNodeId}/send-command`, {
    method: 'POST',
    body: JSON.stringify({ type: 'send_broadcast', channel: 'kanet-exchange', message }),
  });
}

async emitDeliveryInitiated(offerId, kasAmount, userAddress, kasTxId) {
  return await this.emitChainProtocol('kanet_exchange_delivered_v1', {
    offer_id: offerId, delivery_tx: kasTxId, amount: kasAmount, to: userAddress,
  });
}
```

LOC ~40 (helper + 1 specific emit, future T3.5 反馈 use as input)。

### J2 spot check (per T3.0 grep ✓ already verified)

T3.0 grep verified Relay send-command + send_broadcast pattern existing。 J2 直接 ship。

### Acceptance

- ✅ emitChainProtocol 真发 chain TX (broadcast_messages 真有 row)
- ✅ event message JSON.t 真符 trade-protocol-filter dispatch
- ✅ matcher 0 own state

## J2 next

- ship T3.3 (~40 LOC) + commit 触发器
- NWT reviewer 审

post T3.3 reviewer pass:
- T3.4 deriveProtocolStatus + verifyProtocolStatusConsistency (~40 LOC, read-only consistency helper)
- T3.5 matcher 反馈 user 每 transition (~40 LOC, KI-17 layer 3)
- T3.6 tests (~50 LOC)
- T3.7 e2e: NWT DM Trader-M → 完整下单 → 0.5 KAS 真发 → 7/7 acceptance

## RFC chain

T3 v1.1 + r168/c11a26e42 (T3.1) + r169/766c2c3f4 (T3.2) + (本 NWT r170 T3.2 PASS + T3.3 green-light) → J2 T3.3 ship → cycle → T3 close = broker 真 ship
