## 🚀 Sub 7 fire trigger — revote DM (= kanet_oracle_revote_v1)

### Sub 7 内容

```js
// 1. settler 触发 (= Sub 5 already 调 UPDATE revote_round++, Sub 7 加 DM dispatch)
// services/bettor-prediction-settler.js collectMultiOracleVotes dissent 分支:
if (currentRound < MAX_REVOTE_ROUNDS) {
  db.prepare(`UPDATE exchange_offers SET revote_round = revote_round + 1`).run(offer.id);
  
  // NEW: dispatch revote DM to 5 oracle (= maker_relay 当 dispatcher)
  await dispatchRevoteDM(offer, currentRound + 1);  // (Sub 7 新加)
  
  // misbehave++ for non-majority voters (= 现 Sub 5 已实现)
}

async function dispatchRevoteDM(offer, newRound) {
  // maker_relay 当 aggregator 发 revote DM
  const oracleRelayIds = JSON.parse(offer.outcome_oracle_relay_ids);  // 5 oracle ids
  const oracles = sqlite.prepare(`SELECT id, address FROM relay_nodes WHERE id IN (${oracleRelayIds.map(()=>"?").join(",")})`).all(...oracleRelayIds);
  
  const revotePayload = {
    t: 'kanet_oracle_revote_v1',
    offer_id: offer.id,
    new_round: newRound,
    previous_round_tally: { YES, NO, DISPUTE },  // 透明 ack
    deadline_warning: offer.outcome_end_date,
  };
  
  // dispatch via maker_relay (= aggregator owns DM origin)
  for (const oracle of oracles) {
    await sendCommandAsync(offer.maker_relay_id, {
      type: 'send_message', target: oracle.address, message: JSON.stringify(revotePayload)
    });
  }
}

// 2. voter daemon 收 revote DM → 重 derive + 重 sign with revote_round+1
// services/bettor-prediction-voter.js 加 revote DM handler:
// (= voter cron tick 默 scan matched offers WHERE revote_round 已变, 触发 deriveVote 重跑 + 重 sign)
// 实现: voter scan filter 加 revote_round IN payload OR offer.revote_round 来 dedupe
```

## reviewer 加固 Sub 7 — 3 项

### PB-S7-1: revote DM 限流 防 spam

maker_relay 不应在 1 tick 内重发 same offer revote DM. 现 settler 5 min tick → 自然 rate-limit per offer. 加 1 guard: 若 revote_round 已 == new_round (= 已发 DM), skip. 防 settler tick double-fire.

### PB-S7-2: voter 重 LLM call 加 evidence_hash diff check

若 voter 重 fetch evidence + 重 LLM call → 跟 first round evidence_hash 不同?
- 跟 first round 同 (= 99% case, 同 URL 不变内容) → 同 outcome
- 真 diff (= URL 内容变 / Wikipedia edit / etc) → 真 reflection-aware revote

加 log warn 若 round 2 evidence_hash != round 1 evidence_hash (= 提示 source 变).

### PB-S7-3: revote 后 sig signing 必新 timestamp + revote_round

防 replay attack: round 1 sig 不能 round 2 用. payload 加 vote_timestamp (= 已 sign) + revote_round (= Sub 6 已加). 双重 防 replay.

## standby J1 Sub 7 ship ~60 LOC ~1.5h

### sub 8 spec preview (= Sub 7 之后)

Sub 8 = settler 钩 settle SS TX submit. 用 v3 contract redeem script + 5 oracle sig + winner int → submit chain TX. 详 spec 待 Sub 7 PASS 后 r237 提供.

## Phase 4a 总进度

- ship: ~680 LOC (sub 1-6)
- 剩: ~280 LOC (sub 7-11) ~6h
