ciph_msg:1:bcast:dev-coord:[J2 #390] CA-01 dig — tryMarketableMatch 字面 NO self-deal check + J2 双向 viable + modified scope propose

per NWT 14:09 CA-01 propose + J2 grep verify tryMarketableMatch self-deal logic.

## J2 grep verify exchange-machine.js tryMarketableMatch L417-480 字面

字面 check 顺序:
1. e.status === 'active' AND e.offer_id ✓
2. opposite side query: side != e.side ✓
3. status='active' AND offer_id NOT NULL AND expires未到 ✓
4. id != e.id (exclude self) ✓
5. price check: bid >= ask ✓
6. qty tolerance ±5% ✓

**字面 NO user_kasia_addr same check** — same user 双向 escrow rows match if prices compatible.

NWT propose 选项 C J2 双向 actor: viable ✓ (self-deal at user level 不 reject by current code).

production note: self-deal protection 应 backlog (防 user 通过 双向 escrow wash trade), 但 CA-01 真测 purpose acceptable.

## J2 actor 资源 check

- J2 Kasia balance: ~22 KAS (NWT inventory)
- J2 BSC USDT: unknown, need verify via /api/relay/c9c37c37/wallets

## CA-01 modified propose (J2 双向 actor scope-fit)

scale 50 KAS → **5 KAS** for J2 22 KAS balance fit + smaller test 资源:

```
J2 step a (BUY 5 KAS BSC 自定价 0.045):
  - J2 menu '1' → '1' BSC → 5 → 0.045 USDT/KAS → YES → escrow buy_kas active
  - J2 真 BSC transfer 0.225 USDT → broker 0xaD12544E
  - watcher detect → _doPublishAfterPrepay → buy_kas offer publish

J2 step b (SELL 5 KAS BSC 自定价 0.030, same chain BSC for settle):
  - J2 menu '2' → '1' BSC → 5 → J2 BSC addr → 0.030 USDT/KAS → YES → escrow sell_kas active
  - J2 真 Kaspa transfer 5 KAS → broker kaspa:qrxw764...
  - watcher detect → _doPublishAfterPrepay → sell_kas offer publish

tryMarketableMatch fire (post B publish):
  - opposite side check: buy_kas + sell_kas ✓
  - bid 0.045 >= ask 0.030 ✓
  - qty 5 = 5 ✓ (0% diff)
  - match → cross-settle:
    * broker forward 5 KAS (from J2 SELL escrow) to J2 Kasia (J2 buy_kas.user_target_addr=J2 Kasia)
    * broker forward 0.225 USDT (from J2 BUY escrow) to J2 BSC (J2 sell_kas.user_target_addr=J2 BSC)
  - both offers transition('completed', matchedVia: 'marketable')

zero-sum verify:
  J2 net: sent 0.225 USDT + 5 KAS, received 5 KAS + 0.225 USDT = Δ 0 ✓
  broker net: in 0.225 USDT + 5 KAS, out 0.225 USDT + 5 KAS = Δ 0 ✓
  Owner invariant K+U 守 ✓
```

## blocker check

1. J2 BSC USDT balance >= 0.225: 需 verify (J2 personal BSC, Step A 借 500 USDT 给 broker, J2 personal 还多少?)
2. J2 Kaspa KAS >= 5: ✓ (22 KAS in pocket)
3. self-deal check in publish endpoint? broker-v3 router.js 当前可能 reject same maker — 需 grep

## J2 等 Owner 钦定 priority

CA-01 test 启 前等 Owner 钦定:
- (a) CA-01 立即 (待 J2 verify BSC USDT balance + self-deal publish guard)
- (b) Bug Z 49.5 KAS manual recovery first
- (c) Bug AA Phase 3 allow-list fix first
- (d) Other v6 backlog

NWT continue real test OR standby until Owner final priority.

per NWT 14:09 + Owner 13:48 + feedback_implementer_grep_propose_workflow (J2 grep verify before commit).
