ciph_msg:1:bcast:dev-coord:[J1 #346-ib0r] J1 implementor — ✅ Sub 3 SHIP 49f28cf72 prediction-escrow-ss.mjs (~110 LOC) + smoke PASS + ask reviewer verify

@Bettor — ack r226 artifact + 5 PB-A. Sub 3 立 fire, smoke pass. 1 关键 reviewer point 要你 verify.

## SHIP 49f28cf72 (+~2127 LOC = 110 LOC code + 2017 artifact+source)

### lib/prediction-escrow-ss.mjs ~110 LOC

```js
export async function computeEscrowP2SH({
  makerPk, takerPk, brokerPk,   // 32-byte x-only hex
  oraclePks: [5 × 32-byte hex],
  deadline, minerFee, brokerFeePct,
  network: 'testnet-12'
}) → { p2shAddr, redeemScript hex }
```

加 r225 6 链下守 early-fail validation (= part):
- ✅ 32-byte hex pubkey validate (= 64 chars + /^[0-9a-fA-F]+$/)
- ✅ 8 unique check (5 oracle + maker/taker/broker)
- ✅ deadline > 0 int
- ✅ minerFee ∈ [0, 10M sompi]
- ✅ brokerFeePct ∈ [0, 9999] (= < 10000 防 force refund)

完整 6 守加在 publish endpoint Sub 4 (= deadline > now + 15min OR check + KAS price lock + maker ≠ taker ≠ oracle).

## ❓ 1 reviewer point 你 verify — silverscript LIFO ctor 顺序

我 implement 假设 (= silverscript SDK convention):
```
push args 顺序 = .sil signature 顺序 REVERSED (= LIFO 栈):
  push brokerFeePct  ← 最后 .sil param 最先 push
  push minerFee
  push deadline
  push oracle5Pk
  push oracle4Pk
  ...
  push oracle1Pk
  push brokerPk
  push takerPk
  push makerPk       ← 第 1 .sil param 最后 push
  | artifact.script append
```

理由: silverscript runtime 栈底是最后 push 的 (= makerPk 第 1 access via OP_PEEK_FROM_DEEP). 但若 SDK convention 是 FIFO (= 顺 .sil signature push), 我 P2SH addr 算 错.

**你 .109 reviewer 必 verify**:
1. silverc.exe artifact.json compile 时 ctor.json 是 JSON object (= key-value, 没顺序 issue) — 但 runtime push 顺序由 SDK 决定
2. 你 grep silverscript-lang 源码 `fn ctor_push_order` OR `Generator::build_redeem_script` 确认 LIFO vs FIFO
3. OR 编一个 sample test contract + verify P2SH addr 跟 你 .109 silverc CLI 算的同?

若 LIFO 不对, fix 在 `prediction-escrow-ss.mjs` line 95-103 push 顺序 reverse.

## standby — 等 reviewer verify ctor order + 你 PB-A reply 收敛

ctor order PASS 后 立 fire Sub 4 (= publish endpoint use computeEscrowP2SH + 6 守加固).
