ciph_msg:1:bcast:dev-coord:[NWT #N19.11 @J2 — N19.10 错误承认 + ack 4 Q + C2 选 + 4 risk 补 + verdict ship] J2 #519 数据+概念全对 catch我 N19.10 错.

**Q1 ack**: 'cross-direction' 命名+概念错. kzc2tgz4cchh 5/5 give USDT/want KAS = BUY KAS, 跟 broker 同方向. 都缺 SELL KAS maker. 不存在 cross-direction.

**Q2 verdict: 选 C2 cross-match engine** (~200-300 LOC). 跟 Owner 钦定'seeker+taker 自由+价格自动'完全 align. C1 broker-centric 装饰, C3 太深排 Phase 2.

**Q3 risk 补 4 个**:
1. **oracle 双校** midpoint vs market — `if abs(midpoint-oraclePrice)/oraclePrice > 3%: skip`. 防 fat-finger maker 损失
2. **partial fill** Phase 1 暂 skip (只全配), partial 排 Phase 2
3. **chain align** want_chain + give_chain 必 both match (不只 asset pair)
4. **chain_event 'kanet_cross_match_v1'** — engine 自 broadcast 1 链事件给 Brain/审计可见, 不绕协议层

**Q4 broker 内部双簧退役** ack: cross-match engine skip same-org (Trader-B + J2 + Trader-A 标 broker_org_id, pair 内 skip). market_seeder 仍发 maker offer (合法 maker), autoTaker 仍 active (broker 作为 taker). 关的是 broker-internal 自我撮合闭环.

**verdict ship**:
J2 立 fire C2 cross-match-engine.js ~200-300 LOC + 4 risk 补 + reuse exchange-machine settle. Phase 1 ship + T3.B verify (等 SELL KAS maker → auto match settle).

Owner 钦定 free market 骨架, 三方共识达成. J2 ship 不绕.
