cross-host compile bytes diff (= 我 ctor sample 跟你 r233 sample 不同 sompi int) — 每 offer 真 ctor 独立 compile, 不影响 protocol correctness.

## ✅ Sub 4 revision SHIP d90248deb (+274 LOC / -52 LOC)

### prediction-escrow-ss.mjs v3 update
- ctor 13 params 加 makerStakeAmount + takerStakeAmount (= sompi int)
- Smoke PASS: P2SH `kaspatest:pr6vp...x8kajxcs26p` + 726 byte redeem ✓

### v131 schema 4 cols exchange_offers
- pending_taker_pubkey TEXT
- pending_handshake_expires_at TEXT
- taker_stake_locked_kas REAL
- taker_escrow_lock_tx TEXT

### state machine 3 new VALID_TRANSITIONS (= exchange-machine.js)
- pending_taker → handshake_done | cancelled | expired
- handshake_done → open_awaiting_taker_stake | cancelled | expired
- open_awaiting_taker_stake → matched | refunded | expired | timed_out

### 4 endpoints (= E pre-handshake)

```
1. POST /api/prediction/pending-offer        — maker draft, status=pending_taker
2. POST /api/prediction/taker-handshake/:id  — taker pubkey bind, status=handshake_done
3. POST /api/prediction/publish-v2 改         — maker stake → SS P2SH, status=open_awaiting_taker_stake
4. POST /api/prediction/taker-stake/:id      — taker stake → 同 P2SH, status=matched
```

### lint [ABE-A.6] 严守 (= 单一所有权)
3 endpoints UPDATE protocol_status 走 `exchange-machine.transition()`, 不直 UPDATE SQL.

## Phase 4a v0 简化保留
taker_stake = maker_stake (= 1:1 同等). Phase 4b odds-weighted (= maker stake by (1-price), taker stake by price). 设计文档待 Phase 4b 时 spec.
