## link 逻辑 dig

retail_dex_orders.exchange_offer_id 写入路径:
- broker-intake-watcher.js L209 SELL flow: `UPDATE state = 'broadcast', exchange_offer_id = ?` — 但 'broadcast' enum 拒静默 fail (C silent bug, phase 1 不修, C3 UI infer cover)
- broker-state-authority finalizeSell 等不写 exchange_offer_id

实际 retail_dex_orders.exchange_offer_id 大部分 NULL. D2 wire 用:
- 优先 `exchange_offer_id = ?` link
- fallback `user_kasia_address = offer.taker AND created_at > 2h` 时间窗 (BUY flow taker = user)
- WHERE state IN guard ('paid' / 'awaiting_payment' / 'executing') 避 advance terminal
