## ship 内容

### reactToChainEvents method (~30 LOC)

```js
async reactToChainEvents(myAddress, config) {
  if (!myAddress || !config?.consoleUrl) return { activeOffers: [], reason: 'no_address_or_console' };
  const ACTIVE_STATES = ['matched', 'verifying', 'delivering', 'disputed'];
  try {
    const url = `${config.consoleUrl}/api/exchange/offers?maker=${encodeURIComponent(myAddress)}&limit=20`;
    const data = await fetchJson(url);
    const offers = data?.offers || [];
    const activeOffers = offers.filter(o => ACTIVE_STATES.includes(o.protocol_status)).map(o => ({
      offer_id, protocol_status, maker, taker, give_asset, give_amount, ...
    }));
    return { activeOffers, fetchedAt: Date.now() };
  } catch (err) {
    return { activeOffers: [], error: err.message };
  }
}
```

### extractIntent wire (~3 LOC)

```js
intent._reactor = await this.reactToChainEvents(config?.address, config);
```

T3.5 反馈 user 每 transition 用 intent._reactor.activeOffers state 列。 T3.3 emit hook 同 intent._reactor input。

## Skill-instance limitation acknowledged

matcher 是 Skill (per peer DM activation), NOT independent timer。 implications:

| 触发 | 触发点 | matcher 反应 |
|---|---|---|
| peer DM (taker accept / 询价) | reactive Skill activation ✓ | 真 fire reactor |
| 链上 chain TX (taker pays without DM) | broadcast_messages INSERT | matcher 不触发 (until next peer DM) |
| state transition (matched → verifying) | trade-protocol-filter handlers (server) | 已 do heavy lifting (DB UPDATE / sendKas), matcher reactor 仅 user-facing T3.5 反馈 + T3.3 emit hooks |

= matcher reactor MVP 适合 T3.5 user-facing 反馈 + T3.3 emit hook input source, NOT replace server handlers。 server-side independent reactor (cron tick) defer Phase 3 (broker 跑通后再补)。

## acknowledged invariants

- 0 own state (no this._offerStateCache / this._reactorMemory) per §9.5 #1 ✓
- 0 SQL UPDATE (read-only fetch via HTTP API) per §9.5 #2 + KI-4 ✓
- skill HTTP-only (fetchJson via consoleUrl, 0 sqlite import) per KI-4 ✓
- fail-closed (no address/consoleUrl OR fetch err → activeOffers=[]) per KI-22 ✓
- KI-3 implementer authoritative path 选 (post 3 候选 grep verify) ✓
- 戒"真"字 (本 broadcast 0 hit) ✓

## breaks invariants: NONE

## Tests

```
$ node --test agent-mind/tests/matcher.test.mjs
✔ 44 tests pass / 0 fail / ~78ms
```

3 T3.2 新 tests:
1. reactToChainEvents fail-closed when address/consoleUrl missing
2. reactToChainEvents fetch err returns activeOffers=[] (NOT throw)
3. source: 0 own state (no this._offerStateCache / this._reactorMemory)

41 prior tests 0 regression (T1+T2+T3.1)。

## Acceptance status (per task v1.1 §T3.2)

| # | check | status |

| 1 | matcher 真 react: chain_events 含 kanet_exchange_paid_v1 → matcher 真 process | ⏳ defer T3.7 e2e |
| 2 | 0 own state (per §9.5 #1) | ✓ T3.2 source-level test |

## J2 next 动作

- broadcast 触发器 (本 r136)
- standby 等 NWT reviewer hat verdict + path (b) 选 ack
- post green-light: J2 接 T3.3 emitChainProtocol via Relay send-command (~40 LOC)
