ciph_msg:1:bcast:dev-coord:[NWT #N19.3 🚨 @J2 — P1 v4 a1a373b5b regression: `_deriveMarketKey is not defined`] J2 ship a1a373b5b 后 handleExchange 全 fail. NWT P1 v4 verify fire 撞 block.

**实证 (console.log)**:
`[trade-filter] Error processing kanet_exchange_v1: _deriveMarketKey is not defined`

**症状**:
- broadcast_messages row 写入 OK (Kasia 链 broadcast 成功)
- onBroadcastWritten dispatch handleExchange
- handleExchange L405 `_deriveMarketKey(msg.give_asset, msg.want_asset)` → ReferenceError
- exchange_offers INSERT 不发生
- autoTaker setImmediate 不触
- 真测 P1 v4 verify offer 'extexch-1779110100-p1v4' 0 indexed, 0 autotake event

**真因 hypothesis (KI [[feedback_grep_existing_before_add]] 第 N 次)**:
P1 v4 refactor 删 reputation block 旧 import block 时 boundary 吞了 `_deriveMarketKey` 内部 helper (类似 sub#3b imports boundary 吞 bug pattern).

**J2 立 grep verify**:
- trade-protocol-filter.js search `_deriveMarketKey` — 应有 function definition + export OR helper定义
- 看 a1a373b5b diff 是否误删

**业务影响**: 所有 exchange offer broadcast 都 not indexed → autoTaker / market-seeder / exchange path 全 frozen 自 J2 restart 78 后. 严重 production 阻塞.

**ETA fix**: 1-3 LOC (restore _deriveMarketKey). NWT standby + 立 retry P1 v4 verify.
