## SHIP ec8ecb82e (+92/-9 LOC, api/bettor.js)

### A2.b 真 prediction math
- stake = (1 - published_price) × numShares × (1 / KAS_USD)
- KAS_USD via getCachedKasPrice() || 0.034 fallback
- = maker 最大 payout if 输

### 1000 KAS cap (config override default)
- 'kanet_prediction_max_stake_per_offer' default 1000
- > cap → 400 + hint "max shares ≈ X at price Y"

### A1.a Owner trust escrow
- 'kanet_prediction_escrow_addr' (Owner pre-set kaspa: prefix)
- 未设 → 503 'escrow not configured'

### Chain-first 顺序 (NO TX NO STATE CHANGE)
1. validate → relay resolve → stake calc → cap check → escrow_addr config
2. **escrow chain TX 3-attempt** 5/10/15s (sendCommandAsync transfer)
3. broadcast 3-attempt (existing PB1 pattern)
4. DB INSERT 3-attempt (existing PB2 pattern)
- escrow fail → 503 (链上 0 痕迹, CLEAN)
- escrow ok + broadcast fail → 503 + escrow_lock_tx 返 + 'manual refund needed' (Owner Console 手 refund)
- 全 ok + DB fail → 500 + 'scout indexer resync + manual fund_lock cleanup'

### metadata + protocolMsg extend
- DB metadata json: escrow_lock_tx, stake_locked_kas, max_payout_kas, kas_usd_at_publish, settle_outcome_phase='escrowed'
- protocolMsg fields: stake_locked_kas, max_payout_kas, escrow_lock_tx (peers 验证)

### fund_lock 集成 (existing schema 复用)
- lockFunds(makerAddr, offerId, 'KAS', stakeKas) — 防 maker 重复挂超 balance
- failure non-critical (escrow chain 已锁)

## VERIFY 3 smoke PASS

| smoke | result |
|---|---|
| bogus relay_id | ✓ 400 'no resolvable kaspa address' (PB4 path) |
| stake 291176 KAS > cap 1000 | ✓ 400 + hint 'max shares ≈ 34.3 at price 0.01' |
| stake under cap + escrow_addr unset | ✓ 503 'escrow not configured' |

real-chain escrow TX 测 = Owner UAT 时 真 maker_relay broadcast (本 commit 不测真链).

## ⚠ Owner pre-deploy action 必

```bash
# Owner Console UI 设 (OR 直 INSERT config_entries):
INSERT INTO config_entries (key, value, category) VALUES
  ('kanet_prediction_escrow_addr', 'kaspa:qrxxxxx...', 'prediction'),
  ('kanet_prediction_max_stake_per_offer', '1000', 'prediction');
```

不设 escrow_addr → /api/prediction/publish 永远 503. 设了才能 publish.

settler.js + v124 migration:
- v124: ALTER exchange_offers CHECK 约束扩 awaiting_oracle/awaiting_manual_confirm/verified (prediction-specific states 真 enable)
- settler resolved → 计算 payout:
  - maker_won: sendKas(escrow_addr → maker_kaspa_addr, stake_kas) — release stake
  - taker_won: sendKas(escrow_addr → taker, stake_kas) — payout
- exchange-machine.transition delivering→completed 钩 sendKas
- 3-attempt retry + dispute fallback (= 跟现 exchange auto-deliver pattern 一致)
- prediction_reputation_log INSERT 'paid' event 改 phase
- settle_outcome_phase 'escrowed' → 'paid' OR 'refunded'
