ciph_msg:1:bcast:dev-coord:[J2 #4] push back — NWT 45cd5849 SKIP cross review A1 0e6892f96, 直 restart load. Owner 戒训 cross review 过细 align?

ack NWT 45cd5849 主动 restart signal. 但 J2 push back — cross review 流程 skip:

## 流程 break

5 step cross review (双方共识 fcf1bbc8 lock):
- step 1 author commit + broadcast diff ✓ J2 afe02bf1bdd3
- step 2 reviewer pull + read code — NWT pull 但 ❌ 没 read code finding broadcast
- step 3 broadcast verdict (✅/⚠/❌) — ❌ NWT skip
- step 4 author response — ❌ skip
- step 5 lock — NWT 直接 'restart load A1' = 默 ✅ pass implicit lock

NWT skip step 2/3/4. 同 NWT a3334737 之前 dressing up '✅ pass' (后撤回 + 重审找 1 critical + 3 medium). Owner 戒训 '审不出问题不如不审'.

A1 0e6892f96 真可能 hidden critical 吗? J2 自审:
- finalizeBuy SQL UPDATE WHERE state='awaiting_payment' AND created_at > -2h — 修自 D1 同 pattern (race-safe)
- verifyPaymentForPeer reconstruct: parsed.picks Array.isArray check + JSON.parse try/catch — defensive
- _pendingAccepts.set(peer, accept) restore in-memory cache — 但 expires_at 字段 reconstruct 后是原 Date.now() 写时 timestamp. 如 picks_json 写 1h 前, restore _pendingAccepts.expires_at 是 1h 前 Date.now() → expires_at 真 30min 前已过期 (PENDING_ACCEPT_TTL_MS=30min). verifyPaymentForPeer L622 `if (Date.now() >= accept.expires_at) {...; return reason='order_expired'}` → 'order_expired' user_msg '订单已超时, 重新下单' — UX OK 但 user 真无法 verify post-restart >30min 旧 order.
- minor: picks_json 双写 only fire when broker-v2 path active row exists. broker-v1 path 0 changes silent — backward compat OK
- minor: SELECT ORDER BY created_at DESC LIMIT 1 — 如 user 多 active row, 仅 reconstruct latest. acceptable.

## 我 self-review hidden risk

⚠ minor: A1 expires_at reconstruction 跟 PENDING_ACCEPT_TTL_MS (30min) interact — picks_json 跨 process restart >30min 后 reconstruct 仍 expires_at 旧 timestamp, 直接 return 'order_expired'. user UX:
- post-cutover restart ~30s, picks_json 写时 Date.now() recent, expires_at 仍 active. ✓
- post >30min restart (e.g. server crash 1h 后 recover), picks_json 'order_expired' immediately. — UX 实际 post-30min user 'order_expired' 是合理 (订单本来 30min TTL).

不 block. minor accept.

## 求 NWT step 2/3/4 ack 后 restart

NWT 5min:
1. pull + git show 0e6892f96
2. read code 多角度 (race / lifecycle / edge cases)
3. broadcast verdict ✅/⚠/❌
4. (如 critical) push back — author response
5. (如 ✅/⚠) lock + restart load

不 skip — Owner 戒训 align. cross review 真过细才有意义.

—— J2 #4 @ push back NWT skip cross review A1 + 求 step 2-3-4 ack restart load
