ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 — AT-NEW-3 dig (Kaspa reorg handling) + AT-NEW-5 mock 启 + Bug AD candidate] coord-ack: f1bb3d92 (NWT 14:53 path B close) + Owner 13:48 全自动.

## AT-NEW-3 Kaspa reorg handling — Bug AD candidate (P1)

NWT grep verify (broker-bsc-intake-watcher.js + broker-intake-watcher.js + exchange-machine.js):
- reorg / state rollback / chain_events.reverse 全 0 match
- broker 一旦 mark escrow status=active (post prepayment_tx detect), 不再 check chain reorg

real-world Kaspa reorg vector (BPS 10 = 100ms block):
- escrow active + offer published
- Kaspa reorg 真 TX revert (rare ~1% within 1 min, but possible)
- broker chain wallet 真 减 (prepay TX disappeared)
- escrow state stays active (no reverse)
- broker auto-settle 真发 KAS 给 user → broker 真 loss (双重 loss: chain wallet -prepay + auto-deliver -target)

impact: broker chain wallet 真 capital risk if reorg happens 在 settle 前. low probability but P1 vector for production-scale.

## propose J2 ship Bug AD fix (~50 LOC, P1 backlog)

- chain_events table 加 reorg-aware: scan recent prepayment_tx (active escrow rows) every tick, query Kaspa RPC getBlock by tx hash → if NOT in chain (reorged out) → reverse escrow status active → pending_prepay
- exchange-machine.js 加 _handleReorgEvent hook
- 同款 BSC mirror

P1 不 immediate emergency (broker pool currently safe + low reorg probability).

## AT-NEW-5 clock drift mock 启

NWT INSERT mock escrow id 14147d2d-b2a pending_prepay with expires_at = datetime(now, -2 hours) (字面 SQLite format align Bug J fix), expected: sweep tick (~60s) fire _refundEscrow Case 1 (pending_prepay, no chain TX, mark refunded).

监控中 — 等 sweep fire verify Bug J fix robust 大 skew tolerance.

## NWT continue 全自动 sequence

2. IN-03 stress 5 small SELL concurrent (NWT 单方, post path B clean state)
3. Step D Gate.io return cycle (post Owner HP-01+CA-01 timing)
