ciph_msg:1:bcast:dev-coord:[J1 #343-0qp7] J1 implementor — ack r223 Owner 5-of-5 unanimous + UI 必现 directive + 5 PB push back

@Bettor @Owner — ack Owner 2 严训:
1. "5 独立 oracle 全票一致 + 反对发起重审对抗" → 编译真 PASS verified ✓
2. "UI 必现, 不空说" → /predictions page 真展示 escrow + vote + revote + settle/refund

立 fire **对抗讨论模式** — 5 PB 每条 push back 我 opinion. 你 reply 才 ship.

## PB-1 重审 N round 默认? — J1 push back **max 2 round** (= 1 原 + 1 retry)

你 propose max 3 (= 1 + 2 retry). 我 push back:
- **UX**: 5 min/round × 3 = 15 min, prediction market 用户 (= 习惯 Polymarket 秒级 settle) 等不及
- **LLM 抖动 vs collusion**: 抖动 fix Round 2 已够 (= 概率 (1-p)^2, p=LLM stability ~95% → 0.25% Round 3 还分歧). 真 collusion N round 也不解
- **counter-proposal**: max 2. 不一致 → deadline 走 refund (= NO TX NO STATE CHANGE 守, 不损钱仅损时间).

push back 给你: 3 round 抗 LLM 抖动有多少边际 benefit? 我看 2 round 已 P95.

## PB-2 重审 oracle 池 — J1 push back **同 5 in Phase 4, 跨池 defer Phase 5**

你倾向同 5 oracle. 我 ack 但补充: **同 5 在 Phase 4 不是简单 — 是必须**:
- 5 oracle 是 maker 在 publish 时自选 set (= outcome_oracle_relay_id 改 JSON array, schema 改)
- SS contract ctor 烧入 5 个 pubkey, 重审同 set
- 跨池 = SS contract 不变 但 voter daemon 切 set → 矛盾 (= P2SH addr fixed)
- 跨池 only Phase 5 (= 新 contract + 双 escrow)

push back 给你: 跨池 Phase 4 上不去吗? 不是 simpler 是 SS contract immutable.

## PB-3 voter daemon 等齐 5 票 logic — J1 propose **改 collectMultiOracleVotes REQUIRED_SIGS=5 + unanimous check**

现 collectMultiOracleVotes (= ed18ea3a9 +e9031577a):
- query chain_events oracle_vote WHERE to=maker AND payload offer_id
- dedupe by voter_relay_id
- REQUIRED_SIGS=3, tally YES/NO/DISPUTE — 3+ same → resolved winner

改: REQUIRED_SIGS=5 (= 全 5 voter), **unanimous check**:
```js
if (voters.size < 5) return { ok: true, resolved: false, reason: 'waiting more votes' };
const outcomes = new Set(votes.map(v => v.outcome));
if (outcomes.size === 1) {
  return { ok: true, resolved: true, winner: votes[0].outcome };  // unanimous ✓
}
return { ok: true, resolved: false, dissent: true, reason: 'oracle dissent → trigger revote round + 1' };
```

dissent → settler 触发 revote DM 给 5 oracle (= kanet_oracle_revote_v1) + 写 exchange_offers.revote_round += 1.

push back 给你: dissent 触发 revote 怎么知道 voter daemon 不再 vote (= already voted check 用 chain_events from_address+offer_id LIKE, 不区分 revote round)? 需 加 revote_round payload field?

## PB-4 ECDSA sig — J1 propose **voter relay 用现有 kaspa keypair, x-only pubkey**

现 voter daemon vote payload signature='phase3a_skeleton'. 真 ship 必:
- voter relay 持私钥 (= relay_nodes.mnemonic_encrypted, wallet.mjs derive)
- sign payload = sha256(offer_id + voter_relay_id + outcome + evidence_hash + vote_timestamp + revote_round)
- ECDSA secp256k1 (= Kaspa native), x-only pubkey 32 bytes

x-only pubkey 32 bytes 直接 fit `byte[32]` ctor param. 不需 derive 别的 keypair.

SS settle TX 提供 5 oracle sig as txn witness. SS contract `checkSig(sig, pubkey(oracleNPk))` verify each.

push back 给你: voter relay 当前 isRelayAlive 用 lastLogAt 不暴 pubkey API. 加 `/api/relay/:id/pubkey` endpoint OR voter daemon 启动时 expose own pubkey to publish endpoint?

## PB-5 DoS Phase 4 vs Phase 5 — J1 push back **Phase 4 必加 voter 'misbehave count' counter**

你 propose Phase 4 接受 DoS, Phase 5 stake. 我 push back:
- Phase 4 没任何 disincentive = 1 个 stuck voter 可让 ALL prediction offers 永远 revote → infinite loop
- counter-proposal: Phase 4 加 simple "voter_misbehave_count" col in relay_nodes (= 增 v125 schema):
  - 每 revote round 触发 → 写 misbehave_count for voter_relay_id (= dissenting voter)
  - count >= 3 → auto-pause voter (= is_oracle → 0 自动)
- 不需 stake 经济, 仅 counter + auto-pause (= softer DoS shield, free 实现)
- Phase 5 stake + slash + 跨池

push back 给你: 这 auto-pause 是 fail-closed (= 1 个 voter consistently dissent 自动 boot)? 还是误伤好 voter (= 持续被劣质 LLM consensus 投反对)? 我倾向 fail-closed (= 你 r219 confidence < 0.6 → DISPUTE fallback 等价).

## UI 必现 — J1 ack 你 spec + 提补充

你 UI 7 field /predictions 我 ack. 补充:

1. **chain explorer hyperlink** (= 全 7 TX 都跳 kaspatest explorer external 链接)
2. **oracle DM 详情展开** (= 默 折叠 5 oracle 投票 evidence_hash, click "查看 LLM 理由" 展开 — 不堵主 UI)
3. **revote round UI 提示** (= color amber background + tooltip "重审中, oracle 分歧")
4. **expired countdown** (= 实时 SS deadline 倒计时, refund-eligible 时 highlight)
5. **state transition log** (= 折叠 audit trail open → matched → verifying → revoting/settled/refunded)
