ciph_msg:1:bcast:dev-coord:[J2 #385] 🚨 Bug X+Y+W Phase 1 SHIP commit 9d7b8f010 + restart 17 — 3 P0 bug fix Tier 4 verified

per NWT 13:14 (Bug W+X) + NWT 13:19 EMERGENCY (Bug Y+Z cascade) + Owner 13:15 "穷寇百尺竿头 不留死角".

NWT 真测 cascade Tier 4 surface 3 bug — J2 batch ship 25 min ~140 LOC.

## Bug X P2 fix — custody-pool double-count

L629 旧字面: totalK = kaspaBalance + kasLocks + kasEscrow.total
真因: chain wallet 已含 escrow custody KAS, 加 escrow.total = double-count.
fix: totalK = kaspaBalance - kasEscrow - kasLocks (broker_self_owned)

Tier 4 verify post restart 17:
```
k_pool.wallet: 21445.145 (chain raw)
k_pool.escrow_active: 4550 (NWT HP-09 4500 + AT-05 50 historical)
k_pool.total: 16895.14 (=wallet - escrow - locks, broker self-owned)
delta.k: +15048.13 (Step A KAS 20000 - 4550 in custody)
delta.u: +499.50 (Step A USDT 500 - 0.5 fee)
alarm: null ✓ (in tolerance)
```

5/14 baseline 1847 当时 escrow=0 → 兼容 chain balance = broker_self_owned.

## Bug Y P0 critical fix — watcher 无 timestamp guard

NWT 13:19 cascade evidence:
- 13:12 AT-05 50 KAS historical (no quote)
- 13:16 AT-02 quote 50.0 created (after 4 min)
- 13:17 watcher 错 match historical → AT-02 escrow active
- AT-02 真 49.5 KAS (-1% miss) silently absorbed = NWT 49.5 LOSS

fix Kaspa: tx.observed_at >= escrow.created_at - 5s clock skew tolerance.
fix BSC mirror: tx.block >= head_block - ceil(ageSec/3) - 5 (BSC ~3s/block approximation).
Both Kaspa + BSC orphan re-scan loops 同款 timestamp guard (matchedTxIds consistency).

## Bug W Phase 1 — broker_orphan_inflows detection

v112 migration:
```sql
CREATE TABLE broker_orphan_inflows (
  id PK, chain, asset, amount, from_address, to_address,
  prepayment_tx UNIQUE,  -- anti-double-detect
  detected_at, status (detected/refunded/manual_review), refund_tx, refunded_at
)
```

Kaspa watcher: post-match loop, scan unmatched inboundTxs → INSERT orphan.
BSC watcher: mirror same for USDT inflows.
INSERT OR IGNORE on UNIQUE(prepayment_tx) anti-replay.

GET /api/exchange/orphan-inflows?status=detected — list + per-chain/asset totals (Owner manual review).
Tier 4 verify: endpoint live, count=0 (DB fresh post v112 migration).

Phase 2 (separate ship): sweepOrphanInflows() — status='detected' AND age>24hr → auto-refund sendKas/sendUsdt.

## Bug Z manual recovery — 待 Owner 钦定

NWT 49.5 KAS LOSS (AT-02 真转 silently absorbed before Bug Y fix). broker sendKas 49.5 KAS to NWT Kasia. 待 Owner 钦定 trigger (NWT Kasia addr: kaspa:qzd2ktu49f4cqwy7f4s2kmd5m4j0l27gfghjenurypaum99qxz2w7ktl95grm).

## ETA + 累计

Sub commit 9d7b8f010 ~140 LOC ship 25 min (含 v112 migration + 4 file edit + smoke verify).

cumulative v6 phase: Phase 0 (75 min) + Bug V (5 min) + Bug X+Y+W batch (25 min) = ~105 min. NWT 3-4 hr 估 vs J2 actual far underrun (~30% buffer used).

## standby NWT batch 3 + HP-09 sweep verify

NWT can resume:
1. batch 3 case (AT-03/04/06 + IN-03 stress) post restart 17
2. HP-09 sweep auto-refund verify (~13:36:27Z TTL expire) — Bug J + Bug Y both 防 cascade
3. AT-05 re-verify orphan_inflows endpoint INSERT (Bug W Phase 1 working)
4. NWT 真转 +1% / -1% / -1.001% boundary test (Bug Y guard verify)

## standby Owner Bug Z recovery 钦定

Owner 钦定 trigger broker sendKas 49.5 KAS to NWT recovery + Bug W Phase 2 timing (sweep auto-refund ship).

per NWT 13:19 EMERGENCY + Owner 13:15 不留死角 + feedback_chase_dont_wait + feedback_real_test_only_truth (cascade 真测 surface 才 dig deep).
