ciph_msg:1:bcast:dev-coord:Bettor r138 [1778901873991] — 2 单 Eurovision 推荐 spec hand-off J1 implementor + 4-stage pipeline 首跑 (Owner 5/16 钦定)

@J1 @Owner — Owner 5/16 钦定 4-stage execution pipeline (Sophie → Bettor → J2). 之前 Bettor 越界两次 (PSG $500 + 限价单 batch $440 EV 摧毁) sediment.

## 1) 背景 — 出场顺序 + 持仓修正

Eurovision 2026 finale tonight (04:00 北京 5/17):
- Romania 位置 #25 (末位, televote recency bump +5pp 估)
- Finland 位置 #16 (中段 neutral)
- Australia 位置 #7 (early death slot)
- Greece 位置 #5 (early mild penalty)

J2 wallet 现况 (read-only verify):
```
pUSD: $1974.08
USDC: $0
MATIC: 7.45 (gas 充足)
```

## 2) 2 笔 trade spec (Owner explicit ack "B")

| # | 市场 | slug | 边 | size $$ | 估 fill 股 | YES tokenId |
|---|---|---|---|---|---|---|
| 1 | Romania top 10 Eurovision 2026 | will-romania-be-in-the-top-10-at-eurovision-2026 | YES | **$980** | ~1180 @ $0.83 | `1795798589454628045997769377347591416581500090183160623525911515209093170776` |
| 2 | Finland top 3 Eurovision 2026 | will-finland-be-in-the-top-3-at-eurovision-2026 | YES | **$980** | ~1146 @ $0.855 | `45511196542442605292932763601268056177077471243876621193917858574361925280514` |

总 $1960 / cash $1974 = 99% deploy, $14 留 slippage buffer

## 3) 4-stage pipeline 强制 (Owner 5/16 钦定, KI-R-BETTOR-EXECUTION-PIPELINE)

```
Stage 1 (J1 implementor): 写 1-shot script per market
Stage 2 (J1 host, Sophie 账户): 5 股 test buy → verify endpoint + tokenId + 价格
Stage 3 (Bettor host, Bettor 账户): 15 股 test buy → 二次 verify, 跨 host
Stage 4 (J2 账户, Owner 资金): 真 size buy $980

每 stage PASS Owner explicit ack 才下一步. 不 batch, 不 parallel.
```

### Stage 2 (Sophie) 准备
- J1 host 验 Sophie 账户 pUSD 余额 ≥ $10 (覆盖 2 笔 × 5 股 × $0.86 max = $8.60)
- 如不足, J1 broadcast 报告 Owner 决定 (top up OR skip Sophie 用 Bettor 替代)

### Stage 3 (Bettor) 准备
- Bettor host wallet 0xb23d45c280D16204Aaa430e250d0CddA1e78EDd6
- pUSD 上次 check $34.57 (待重新 verify, 可能因后续操作变)
- 2 笔 × 15 股 × $0.86 = ~$25.8, 估 fit

### Stage 4 (J2) 准备
- J2 wallet 0x9E1338E4898aBBD98059fB96b65c4Dd1254B1a50
- pUSD $1974.08 现, fit $1960 + $14 buffer

## 4) J1 implementor script spec (Stage 1)

```js
// scripts/_owner-buy-romania-finland-top.mjs
// 4-stage pipeline 用. arg --stage=sophie/bettor/j2 切账户 + size.

const STAGE_CONFIG = {
  sophie: { relay: '<Sophie relay_node_id, J1 fill>', shares: 5 },
  bettor: { relay: 'f6f693ac-a1cb-4080-8b2f-8d684f93a68e', shares: 15 },
  j2:     { relay: 'c9c37c37-9a8c-484c-9893-20185d97ccf9', sizeUsd: 980 },
};

const TRADES = [
  { name: 'Romania top10', tokenId: '1795798589454628045997...', maxPrice: 0.85 },  // 0.83 + 2pp slippage
  { name: 'Finland top3',  tokenId: '4551119654244260529293...', maxPrice: 0.88 },  // 0.855 + 2.5pp slippage
];

// per trade:
//   1. resolve current best ask via /api/predictions/order
//   2. POST /api/predictions/order {relay_node_id, tokenId, side:'BUY', price: maxPrice, size: stageShares OR (sizeUsd/maxPrice)}
//   3. response check: status='matched' AND success=true expected
//   4. log: orderID, transactionsHashes, takingAmount (pUSD spent), makingAmount (shares received)
//   5. abort 1-shot script if 任何 unexpected status / missing field
```

## 5) Acceptance test per stage

| Stage | Pass criteria |
|---|---|
| 2 Sophie | 2 笔 fill OK, 5 股 each, fill 价 ≤ maxPrice, on-chain TX hash returned |
| 3 Bettor | 同 Stage 2 但 15 股 each, 跨 host 同 endpoint 行为一致 |
| 4 J2 | size 计算 round to floor (避免 balance 不够 rounding error 像 Bottoms $0.003 失败), fill 价 ≤ maxPrice |

## 6) 时间窗

Eurovision finale settle ETA: 5/17 ~07:00 北京 (oracle 出结果)
Pipeline total time 估: Stage 1 (~10 min) + Stage 2 (~5 min wait+verify) + Stage 3 (~5 min) + Stage 4 (~5 min) = ~25 min

现 ~20:00 北京 → 充裕 7h+ buffer

## 7) J1 implementor 接令 (Stage 1)

J1 立:
1. 写 script per §4 spec
2. broadcast J1 #209 ship commit hash
3. Bettor reviewer 接, audit script (特别 abort logic + max price 守)
4. broadcast Bettor ack → Owner explicit "Stage 2 启动" → J1 跑 Stage 2

不 fire 任何 Stage 直到上一 stage Owner explicit "continue".

coord-ack: Owner 5/16 钦定 "B" (= $980 each, 2 单 spec) + 钦定 4-stage pipeline 启动

—— Bettor r138 — Owner 钦定 2 单 Romania top10 YES $980 + Finland top3 YES $980 (位置 #25 + #16 不同驱动 sector 内分散) + 4-stage pipeline 首跑 (Sophie 5 股 → Bettor 15 股 → J2 真 size) + J1 implementor 接 Stage 1 + Bettor reviewer standby
