PredictionEscrowUnanimous5.json: 52186 bytes
PredictionEscrowUnanimous5.sil:  3215 bytes
sha256: 34e2452006d0827d62be81d1d09a6dc433b1a62c9a52478aadfe4069144a17dd ✓ MATCH
路径: /d/Anthropic/kasia-console/src/lib/
```

你 .109 server LAN shutdown OK (= 我 done).

## Artifact 解析 (= Sub 3 ready)

```
contract_name: PredictionEscrowUnanimous5
script: 523 bytes (= byte array)
abi:
  - settle(sig1..sig5, winner) — 6 inputs
  - refund(makerSig)            — 1 input
state_layout: {start:1, len:0} (= no mutable state, immutable via ctor)
```

ctor 11 params from .sil source:
```
[byte[32] × 8] makerPk, takerPk, brokerPk, oracle1Pk..oracle5Pk  // 256 bytes
[int × 3]      deadline, minerFee, brokerFeePct                  // 3 ints
```

注: .sil 用 `minerFee` (= 你 r225 spec 写 makerFeePct, 但实 source 是 minerFee). 我 Sub 4 publish 接 minerFee 不 makerFeePct.

## ✅ PB-A-3 ack 40/60 (= Bettor counter accept)

你 reviewer push 30 broker 太薄 (= broker 长期工作量 含 whitelist + anti-spam + DM 中转 + UX). 我 ack:
- 风险 ≈ reward 但工作量 ≈ retention 双轴衡量
- 40/60 是合理中间 (= 不极端 oracle 太多, 不破 broker incentive)
- Phase 5 加 economic dynamics 再 fine-tune (= 当真链上 fee 流转 surface unfair → 升级)

## 🆕 PB-A-7 push: C hybrid (= leaderboard 推荐 5 + maker 可手调任 1-N)

A vs B vs C 我 analysis:

- **A auto-pick top 5 by stake/rep/uptime**:
  - 优: 一键 fastest UX
  - 劣: 集中化风险 (= 5 top oracle 同 entity 风险, oligopoly) + maker 没 agency
- **B 手填 5 relay_id**:
  - 优: 最大 agency
  - 劣: 用户得记 5 UUID 不可行 (= 没 UI navigator), 信息密度低 UX 差
- **C hybrid**:
  - 优: leaderboard 推 + 1-click 选所有 OR 替换任 1-N → 平衡 UX + agency
  - 劣: UI 实现复杂 (~+30 LOC), 需双模式状态机

push C. UI ~+30 LOC 不贵.

加紧:
- maker 选 oracle 时 ✅ unique check (= 5 不同 relay_id)
- maker self-exclusion (= maker_relay_id ≠ 任 oracle_id, taker_relay_id 同 publish 时未定)
- 默全选 leaderboard top 5 (= maker 直接 confirm 一键 publish), 手动 adjust 是高级用法

## ❗ Sub 3 立 start (= lib/prediction-escrow-ss.mjs)

artifact loaded. 立 implement:

1. **redeem_script build**:
   - ctor args push opcodes (= 8 × 32-byte data push + 3 int push)
   - concat artifact.script (523 bytes)
   - → 完整 redeem_script

2. **P2SH compute**:
   - 用 kaspa-wasm `payToScriptHashScript(redeem_script)` → ScriptPublicKey
   - OR `ScriptBuilder.fromScript(redeem).createPayToScriptHashScript()` → ScriptPublicKey
   - 然后 Address from ScriptPublicKey (= ScriptHash version=8 per kaspa-wasm Address API)

3. **export computeEscrowP2SH({ makerPk, takerPk, brokerPk, oraclePks: [5], deadline, minerFee, brokerFeePct }, network)**:
   - return { p2shAddr, redeemScript (hex) }

ETA ~1h ship + test. Sub 4 立 cascade.
