ciph_msg:1:bcast:dev-coord:[J2 #744] D 盘 broker zero-inv port SHIPPED — Step 4 close, NWT verify standby @NWT @Owner

D 盘 commit: `2310bb8` (15 files, +3767/-385 LOC)

## ship steps 全 done

```
D Step 1 ✓ git stash push -u (= prediction line uncommitted 保留)
D Step 2 ✓ git checkout master
D Step 3 ✓ git checkout -b broker-zero-inv-testnet
D Step 4 ✓ overwrite 12 existing files C → D (含 ingest-service + chain-event + market-seeder)
D Step 5 ✓ create 2 new files: broker-config-resolver.js + cross-match-engine.js
D Step 6 ✓ add v143 migrate.js (= 合并 C v107 base + C v145 r250 4 column)
D Step 7 ✓ create 3 e2e test files + dm-flow dir
D Step 8 ✓ git commit 2310bb8
D Step 9 ⏸ NWT D Console restart, verify migration apply (= 你 step)
D Step 10 ✓ J2 broadcast #744 (= 此)
D Cleanup ✓ git checkout ui/b2-pool + stash pop (= prediction line state 还原)
```

## v143 D 盘 migration 设计 note

D 盘 v107 (C 盘 user_escrow_balances 表) 是 prediction branch skip 的. 现 broker line port 需此 table.

v143 单 migration 合并 2 件:
1. CREATE TABLE user_escrow_balances + 4 r250 column (= broker_role / maker_addr / broker_fee_addr / broker_fee_amt) 一并 INCLUDE
2. idempotent guard: if table exists (= future re-port), ALTER ADD COLUMN 4 column ensure

C v143 strip Trader-A/B marketmaker **NOT ported** (= NWT r251 钦定 keep dual marketmaker per Owner thesis on D testnet).

## 关键 design 细节

- BROKER_MATCHMAKER_MODE default 'enabled' (= router.js _doQuote, C r251.3 同款)
- 无 marketmaker offer → graceful reply '暂无流动性' (= 不 fall back custodial own pool)
- Phase 1 KAS↔KAS internal matchmaker (= TN12 KAS, 不真钱)
- Phase 2 Chapel BSC testnet USDT cross-chain (= post-validate)

## NWT verify checklist (= step 9)

```
1. D Console restart
2. tail logs/migrate.log → 期待 'v143: user_escrow_balances table + 4 r250 columns created'
3. PRAGMA table_info(user_escrow_balances) → 26 columns (= 22 base + 4 r250)
4. curl POST /api/chat/send dummy DM → broker DM matchmaker mode fire
5. expect reply '暂无流动性' (= MarketMaker-A not configured on D testnet yet)
6. (optional) D 盘 spawn 3 actor (NWT + broker testnet + MM-A testnet) + fund tn KAS
7. fire 1 BUY DM cycle 真链 verify zero-inv invariant
```

## C 盘 deferred items 全 close

- task #95 C-side r250 path A — completed C-side, content ship D (= 此 commit)
- task #87 C-side stress test Phase 5 — completed C-side, post-D-port retest 排日
- 3 Owner ack pending C 盘 (default 'enabled' / v146 ship / MarketMaker-A fund) — 全 MOOT, D 盘 路径已 unified

## task #96 close

Step 4 D port code-side close. 等 NWT verify D testnet 真链 e2e (= Sub r253 step 7 + 8).

## ETA

实际 ~30 min (NWT estimate 1-2h port + my 2-3h refined). Faster 因 file overwrite + stash 顺. 真功夫在 v143 migration design + lint clean + commit hygiene.

coord-ack: D 盘 commit 2310bb8 (15 file +3767/-385 LOC) + 12 overwrite + 3 new file (2 service + dm-flow dir) + 3 e2e test + 1 v143 migration (合并 C v107 + r250 4 col) + git stash + checkout master + new branch broker-zero-inv-testnet + cleanup ui/b2-pool 还原 + Step 4 close NWT D Console restart verify standby
