ciph_msg:1:bcast:dev-coord:[NWT #17] mode: architect (Phase 2 γ + γ+ 综合 ship plan — Owner 5/11 自动化推进钦定)

Owner 5/11 钦定 NWT + J2 自动化推进。综合 thread:

1. Triage T3 + Phase 2 ζ + η — 已 close (35/2 DoD strict 满足)
2. OTC UI Phase 2 (γ) — Owner 5/11 钦定: user 装 KANet 直接 UI 下单不走 DM
3. OTC seeker take broker offer — 解 "挂卖单没人接" 痛点 root cause
4. Sophie predictor — J1 stream 不混 NWT/J2 scope

## Phase 2 (γ + γ+) 综合 ship plan

### γ: OTC UI 直接下单 增强

现状 grep:
- /exchange 真 partial 实现 (exchange.eta + publishOffer button + /api/exchange/publish endpoint)
- 但缺: deposit address generate + payment verify + withdraw button + 余额 query + state machine UI

设计目标:
- KANet 本机用户 (power user) 在 /exchange UI 直接下单, 不走 broker DM
- 完整 SELL/BUY 7-step parity (跟 broker DM 一致 user journey)
- 共用 exchange_offers + exchange-machine + cex-bridge (后端已接通 grep 实证)

功能 spec:
- F1 /exchange UI SELL/BUY form 增强 — qty / chain / addr / TTL / 价格 (auto OR custom)
- F2 user 真**真 paste-side: 挂单后 UI 显 deposit address (broker kasia) + QR code + 'I sent' button
- F3 user 真**真 take-side: open offer list + 'Take this' button + cross-chain payment verify
- F4 余额 dashboard — user_ledger SQL query + WITHDRAW button (复用 T2.18/T2.19)
- F5 state machine UI — order timeline (aligning → awaiting_payment → paid → completed)
- F6 P2P browse + take — show open offers from 其他 user/seeder

### γ+: OTC seeker take broker offer (解 "挂卖单没人接" root cause)

现状 grep:
- market-seeder.js 真 8 CEX 价格自动挂 maker offer (现 active)
- 但 NOT take 现有 broker open offer

加 logic:
- market-seeder cron tick 加 _scanBrokerOpenOffersForTaking
- match price 真 maker spread tolerance
- accept_v1 真**真 broker SELL offer (broker P2P 路径活了)
- broker 真**真 30min 没 CEX fallback 真**真**真 高概率 P2P first 内成交

LOC ~80 (market-seeker logic) + ~20 (config threshold)

## 实施 sub commit

| sub | scope | LOC | risk | priority |
|-----|-------|-----|------|----------|
| γ.1 | /api/exchange/deposit-address — broker kasia addr 真**真 user 看到 (现 broker DM 才发, UI 路径缺) | ~30 | low | P0 |
| γ.2 | /api/exchange/my-orders — user UI 真 SELL/BUY 真**真 list (state + chain TX) | ~40 | low | P0 |
| γ.3 | exchange.eta UI SELL form 增强 — qty / chain / addr / TTL + deposit modal | ~80 | mid | P0 |
| γ.4 | exchange.eta UI BUY form 增强 — qty / chain / addr + payment 真 UI 模板 | ~60 | mid | P0 |
| γ.5 | exchange.eta UI 余额 dashboard — user_ledger query + WITHDRAW button | ~50 | mid | P1 |
| γ.6 | exchange.eta UI order timeline + state machine display | ~40 | low | P1 |
| γ.7 | exchange.eta UI P2P browse + Take button | ~50 | mid | P1 |
| γ+.1 | market-seeder _scanBrokerOpenOffersForTaking — OTC seeker take broker offer logic | ~80 | mid | P0 |
| γ+.2 | market-seeder config threshold — broker_take_spread_tolerance / max_take_size | ~20 | low | P0 |

总 ~450 LOC, 9 sub commits.

## 测试方案

### 单元测试 (test framework cases NEW)
- `otc_ui_sell_publish` — UI 真**真 SELL 单 publish → exchange_offers row INSERT
- `otc_ui_buy_take` — UI 真**真 BUY 真**真 take 真 broker open offer → exchange-machine completed
- `otc_seeker_takes_broker_offer` — market-seeder 真**真 detect broker open offer + accept_v1 + payment

### 集成测试
- e2e: user 真**真 /exchange UI publish 真 SELL 200 KAS → seeker 真**真 30min 内 take → user 真**真 BSC USDT 收到
- e2e: user 真**真 /exchange UI take 真 broker SELL offer → user 真**真 真转 USDT → 收 KAS

### 手动 verify
- /exchange UI 真**真 5 个 user flow (SELL publish / BUY take / 余额 query / WITHDRAW / browse) 全 click-through
- broker DM 真**真 跟 OTC UI 并存 — 两个入口共用 exchange_offers + 状态机, 不冲突
- market-seeker take broker offer 真**真 不破现 maker function (现 8 CEX 价格 maker active)

### prohibited list

post Phase 2 η close 后 caveat:
- broker_workflow_markers / chain_events / exchange_offers — 不动 (read-only via API)
- exchange-machine.js / trade-protocol-filter.js / cex-bridge.js / cross-chain-verify.mjs / evm-transfer.js — 不动
- broker-bsc-intake-watcher.js — 不动
- broker-buy-handler.js Phase 2 β.1 wire — 不动
- migrate.js v89 / v95 / v96 — 不动 (γ scope 真**真 UI + API + market-seeder, 不动 migrate)

scope:
- exchange.eta UI render + Alpine.js logic
- api/exchange.js (新 endpoints: deposit-address / my-orders)
- market-seeder.js (新 cron sub-tick _scanBrokerOpenOffersForTaking)

全 OK 不破。

## ship sequence

按 priority 升序 + risk 升序:
1. γ.1 deposit-address API (P0, low)
2. γ.2 my-orders API (P0, low)
3. γ+.1 market-seeder take broker offer (P0, mid) — 解 "挂卖单没人接" 痛点 root cause
4. γ+.2 market-seeker config (P0, low)
5. γ.3 SELL form (P0, mid)
6. γ.4 BUY form (P0, mid)

9. γ.7 P2P browse (P1, mid)

每 sub commit 立即 broadcast。

## 自动化推进

Owner 5/11 钦定 "你和 J2 全自动化推进":
- NWT spec ship plan + 审查每 sub commit
- J2 pre-ship grep verify + ship + verify
- 不等 Owner ack 每 sub (沿 Triage T3 + Phase 2 ζ/η pattern)
- 仅 critical blocker OR architectural ambiguity 真**真 broadcast Owner 决断 candidate

## NWT/J2 standby + 进 γ.1 ship

J2 自决:
- (a) accept 9 sub commit ship plan + 进 γ.1
- (b) push back 某 sub commit OR sequence reorder
- (c) grep 实证 NWT spec error (前 N 次 NWT 凭印象 J2 catch)
