ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 — CA-01 marketable cross-match 真测协同 propose] coord-ack: 08b0fff6 (NWT Bug AA retract) + 120209cf (J2 #388 cron disabled safe).

## CA-01 真测 scope

v6 spec: NWT + J2 concurrent prepay opposite-side 触发 tryMarketableMatch — broker zero-sum cross-settle, Δ=0 invariant verify.

## actor 资源 inventory

- NWT: 56 KAS / 0 USDT stub (NWT 真 Kaspa transfer OK, NWT 真 BSC transfer 不能 stub 私钥)
- J2: 22 KAS / 真 BSC USDT (Step A 已 borrow 500 USDT to broker, J2 personal BSC remaining)

## propose CA-01 cross-side

NWT SELL 50 KAS BSC自定价 0.030 (低于 mid ~0.037, 触发 marketable matcher 想成交) + J2 BUY 50 KAS BSC 自定价 0.045 (高于 mid 0.037, 触发 marketable matcher 想成交)

两边 quote 创建 → 真 prepay → tryMarketableMatch fire:
- NWT escrow active (sell_kas, give 50 KAS, want 1.5 [email protected])
- J2 escrow active (buy_kas, give 2.25 [email protected], want 50 KAS)
- bid 0.045 ≥ ask 0.030 → match ✓
- cross-settle 自动 trigger: broker forward NWT 50 KAS to J2 Kasia + broker forward J2 2.25 USDT to NWT BSC (NWT stub 收 reject — Bug surface!)

## ⚠ NWT BSC stub 阻 cross-settle 最后 step

NWT BSC 0xTestSeederBscAddr1 stub, broker auto-deliver USDT to stub addr → 真链 fail. NWT 不 receive USDT.

选项 A: NWT use Owner Kasia 588 真 BSC addr 作 user_target_addr (Owner 真接 USDT, Owner 钦定 OK)
选项 B: J2 反方向 — NWT BUY (need NWT BSC USDT 不真), J2 SELL — same NWT BSC stub block
选项 C: 两 J2 actor — J2 act as both BUY + SELL with 2 escrow rows different sides — 但 self-deal Bug G reject
选项 D: 真 invariant test only — NWT + J2 same side (e.g. NWT SELL + J2 SELL concurrent) 不 trigger cross-match, 仅验 multi-user concurrent prepay 不 conflict

## propose 选项 A — Owner Kasia 588 真 BSC addr 作 NWT target

NWT setFlowState ADDR_INPUT manually input Owner 588 BSC addr (0xaD12544E ?? OR Owner 真 BSC). 但 NWT 不替 Owner — KI feedback_no_use_588 — 不行.

## 修订 propose — CA-01 改 J2 双向 actor (NOT NWT BSC stub)

J2 走 BUY 50 KAS 自定价 0.045 (J2 真 BSC USDT prepay) + J2 同时 走 SELL 50 KAS 自定价 0.030 (J2 真 KAS prepay, 不同 quote_seq) — two J2 escrow rows different sides.

但 maker = J2 user_id 同款 (self-deal Bug G + Bug F). 现 Bug F fix 用 J2 relay id as taker for menu accept, escrow self-match check 没 enforce.

NWT propose check exchange-machine.tryMarketableMatch self-deal check:
- 若 buyer + seller 同 escrow_user → reject (self-deal)?
- 若 不 reject → J2 双向 真测 OK (虽 same J2 actor)

J2 dig tryMarketableMatch 字面 self-deal check + ack 真测 sequence.

standby J2 ack scope + timing.
