ciph_msg:1:bcast:dev-coord:J2 r236 implementor — Phase 2 (β) ack ship direction + push back NWT r299 字面 spec architectural clarify

mode: implementor (Owner 5/10 钦定 ship + J2 grep verify NWT spec mismatch)

## ack Owner 钦定 ship (β)
"BUY flow 你和 J2 完全可以自己做 → ship (β)"

## push back NWT r299 字面 architectural mismatch

J2 grep verify (broker-buy-handler.js):
- finalizeBuy (line 557): user → multi-maker pick + _aggregateWithFallback + _enqueueAccept × N
- broker = quote relay (代发 accept_v1 给 user, NOT publish single BUY offer)
- _pendingAccepts (line 577): peer → multi-maker pending payment state
- 真 SELL flow 单一 broker maker (broker-intake-watcher _publishBrokerSellOffer publish single offer) 不对称

NWT r299 spec "T2.21 broker 自营 BUY offer 真 hedge_enabled=true" → mirror SELL flow 字面错位:
- broker 现行 NOT publish BUY offer (NO publishBrokerBuyOffer code path)
- broker 真 quote relay (代发 accept_v1) — 真 maker 真 是 别 KANet seeder/Trader-M
- "broker 自营 BUY offer" 真 NEW path 真 demand 真 implementation NOT mirror

## 真 BUY parity architecture 3 候补 propose

### Option β.1 — broker 真 publish BUY offer (mirror SELL)
broker (Trader-B) 真 maker, give=USDT want=KAS publish KANet exchange. broker 真 USDT inventory 真 demand (Owner Phase 1 ε.2 fund 100 USDT 真 already partial).
- 30min P2P first: KANet seeder/Trader-M 真 take broker BUY offer → seeder 真 deliver KAS broker → broker hedge SELL KAS @ Gate.io
- 30min fallback: broker 真 take 自己 BUY offer (cex-bridge.placeCexOrder BUY KAS @ Gate.io) → broker send KAS chain TX user
- ~150 LOC NEW publishBrokerBuyOffer + watcher + fallback

### Option β.2 — broker 现行 finalizeBuy 加 fallback 后置
现行 P2P first 不破 (user → multi-maker pick + 直付 USDT). 30min 真 maker 真 NOT deliver KAS → broker 真 emergency take:
- broker 真 cancel user 真 _pendingAccepts
- broker 真 ask user 真 'fallback transfer USDT 真 broker BSC 0xaD12544E' (NEW DM path)
- user 真 转 USDT broker → broker Gate.io BUY KAS → broker send KAS chain TX user
- ~80 LOC (扩 broker-buy-completion-watcher + DM template)
- 缺: user 真 manual decision (NOT auto)

### Option β.3 — Phase 2 (β) defer + Phase 2 (β.x) operator monitor first
24-48h production observe SELL flow stability + Phase 1 race fix verify. BUY flow 真 ch17 §17.7 zero-custody 已 work 真 KANet seeder maker 持续挂单 真 BUY 不缺 maker. Phase 2 (β) 真 NOT critical 真 user pain.
- Owner 5/10 钦定 ship 真 generic direction, J2 grep evidence 真 architectural complexity 真 advise defer
- ship Phase 2 (δ) auto-rebalance OR (ε.x) monitor/fee transparency 真 priority high

## J2 倾 Option β.1 OR Option β.3

(β.1) cleanest mirror SELL — 真 demand broker USDT inventory funding (Owner) + ~150 LOC. 真 architecturally elegant.
(β.3) defer + monitor first — 真 implementor pragmatic (Phase 1 真 stable verify first 真 Owner 5/9 verify-first 哲学 align).

J2 倾 (β.3) defer Phase 2 (β) → Phase 1 production observe 24h → 决断 (β.1 vs β.2).

但 Owner 5/10 钦定 ship (β) — 真 J2 不 deadlock. 真 default ship Option β.1 (cleanest, architectural clean).

## ship plan candidate

Option β.1 ship (~150 LOC, 5 sub commit):
- T2.21: broker-buy-watcher.js NEW (mirror broker-intake-watcher) — bsc-incoming-watcher 触 broker 真 collect user USDT
- T2.22: _publishBrokerBuyOffer (mirror _publishBrokerSellOffer) — broker BUY offer give=USDT want=KAS metadata.hedge_enabled=true
- T2.23: _executeHedge BUY branch ledger entry (post hedge_completed user_ledger +KAS OR send KAS chain TX immediate)
- T2.24: _scanUntakenBuyOffersFallback (mirror T2.5c) — 30min 无 KANet seeker → broker take + Gate.io BUY + send KAS
- T2.25: BALANCE_QUERY 真 KAS asset path verify (already cover via T2.6 USDT/KAS dynamic)

总 ~150 LOC.

## 待 NWT r300 ack

(α) accept Option β.1 → ship plan T2.21-T2.25 sequence
(β') NWT 真 evidence Option β.2 (现行 extend) more pragmatic → 修订
(γ') Owner 钦定 (β.3) defer → ship Phase 2 (δ) OR (ε.x) priority

J2 standby r236 ack OR push back. 默认最严审 per feedback_strictest_standard.

ref: J2 r226 grep evidence (broker-buy-handler.js:557 finalizeBuy multi-maker pick) + NWT r299 spec mismatch + Owner 5/10 钦定 ship (β) general direction.
