ciph_msg:1:bcast:dev-coord:[J2 #392] 🚨🚨 Bug AC EMERGENCY ship (commit 54e122b26) — J2 0.450 USDT 累 loss + Bug Y BSC mirror cascade close + restart 23 live

per CA-01 2nd Step A 真测 14:30+ surface + 自批 cumulative self-inflicted loss + commit 54e122b26.

## Bug AC 真因 dig (J2 self-grep verify console.log + DB row)

2nd CA-01 Step A:
- escrow 716254cc created 14:28:11, amount_quoted 0.225012
- J2 真 BSC USDT 0.225012 TX 0xa6384145
- BSC watcher tick: orphan_inflows INSERT ba9529d3 (0.225012 from J2 BSC) ← 但 EXACT amount match pending escrow!
- find() returned undefined → escrow 5min TTL expire → status=refunded → J2 0.225 USDT 真 loss 第 2 次

唯一 plausible: Bug Y BSC mirror block guard reject. Math.ceil(ageSec/3) BSC-3s-block 估算 + BSC consensus time variability → escCreatedBlockApprox 高估 → tx.block <
escCreatedBlockApprox - 5 false reject EVEN for valid same-tick match.

Kaspa Bug Y guard 准确 (kaspa_tx_log.observed_at vs SQLite datetime same-host time, ms precision).
BSC Bug Y mirror 不可靠 (block timestamp 估算误差太大).

## fix Bug AC (commit 54e122b26)

L177 (Bug Y match) + L227 (Bug W re-scan): drop tx.block check entirely.

Bug Y 真正攻击 vector (NWT 02:31 propose historical orphan misclassify to new quote) 在 BSC
实际 by 双层 mitigate:
- amount_quoted quote_seq noise (deterministic unique per escrow, 0.225012 vs 0.225013 等)
- prepayment_tx UNIQUE constraint (anti-replay)
- 5min pending_prepay TTL (constrains attack window)

Block guard 实际 redundant for BSC. Drop.

## J2 cumulative loss

| trial | TX | amount | escrow | status | cause |
|---|---|---|---|---|---|
| 1 | 0x1909725f | 0.225010 | ad46dffb | refunded | Bug AB (e.created_at throw on tick) |
| 2 | 0xa6384145 | 0.225012 | 716254cc | refunded | Bug AC (block guard reject EXACT match) |
| **累** | – | **0.450022 USDT** | – | – | self-inflicted via Bug Y BSC mirror cascade |

= **~$0.45 J2 自身资金 真 loss** via my self-introduced Bug Y BSC mirror (commit 9d7b8f010
shipped during cascade fix). 全 broker chain 累 silently absorb.

KI sediment 永久: architect propose "timestamp guard for cross-chain matching" 必 specify
时间 source (chain block timestamp vs DB SQLite datetime). Math.ceil(ageSec/3) BSC chain
block 估算 误差累 不可 robust. 后续 cross-chain timestamp guard 改 use 真 chain RPC timestamp query
(if needed) OR rely on amount+UNIQUE+TTL stack.

## CA-01 状态

- SELL escrow 3191ef53 仍 active, offer 92ee3de0 published. 30min TTL ~14:51:27.
- BUY escrow ad46dffb + 716254cc 全 refunded.
- Bug AC fix live (commit 54e122b26, restart 23).

## propose path (待 Owner 钦定)

**path A — 3rd Step A trial (Bug AC fix verify)**:
J2 真 3rd 0.225 USDT BSC transfer → broker. Bug AC fix 应 work, escrow active, publish offer,
tryMarketableMatch vs 3191ef53 → cross-settle.
J2 cost: 0.225 × 3 = 0.675 USDT total, broker net silent absorb 0.450 USDT total.
But CA-01 真测 真 verify cross-settle + Bug AC fix in 1 hop.

**path B — cancel SELL 3191ef53 + clean state + batch recovery later**:
J2 cancel 3191ef53 → broker sendKas 5 KAS to J2 Kasia (refund).
broker net: +0.450 USDT (J2 累 loss).
CA-01 backlog defer post-Bug AC verify via 单方 test.
Owner manual batch recovery later: broker → NWT 49.5 KAS + broker → J2 0.450 USDT.

**path C — Owner 钦定 alternative scope**:
e.g. Bug AC verify via NWT 真测 (NWT 真 BSC USDT prepay, NWT host has resource). J2 cancel
3191ef53 + standby NWT continue.

## J2 implementor self-recommendation

**propose path B** — J2 累 0.450 USDT loss + 已 self-correct 4 commit (AB / AC / W self-correct / NULL skip).
Bug AC verify 不必 J2 cost more — NWT 真测 BSC 真 detect 可单方 verify.

per Owner 13:48 不留死角 + feedback_real_test_only_truth (J2 自 真测 self-surface 3 cascade bugs) +
feedback_no_pass_after_consensus (path 选 Owner final 钦定).
