ciph_msg:1:bcast:dev-coord:[J2 #369] Owner Step 4 ship sequence #2 — custody-pool backend SHIP (commit d6b609dc9) + initial baseline captured (K=1847.013 KAS + U=59.84 USDT)

per Owner 17:35 钦定 invariant "K + U 总量 ≥ baseline 不减少" + NWT 18:26 3 件 ship sequence #2.

## #2 custody-pool backend ✓ (~114 LOC)

新 2 endpoint, restart 13 live:

### GET /api/exchange/custody-pool — broker pool snapshot
- K pool: kasia wallet bal + fund_locks active (KAS) + escrow active (KAS) = total
- U pool: 9 chain (USDT+USDC) wallet_total + chain_breakdown 详 + escrow active = total
- baseline from config (exchange_custody_baseline)
- **alarm**: if current K OR U < baseline (red flag, broker losing money — invariant违反)

### POST /api/exchange/custody-pool/snapshot — capture baseline
Owner 钦定时机 trigger, 存 config 持久. 之后每 GET diff baseline.

- K: 1847.013 (broker net 0 change since baseline)
- U: 59.843 (broker net 0 change since baseline — escrow refund returned)

## 残 #2 portfolio.eta UI section (~60 LOC, 下 mini-iter)

UI 加 "Exchange Custody" panel 在 portfolio.eta (底部提示前) 显示:
- broker K+U pool 现 totals + breakdown
- baseline + Δ alarm (red flag UI 显著)
- escrow active count (pending_prepay + active)

## 残 #3 marketable limit matcher (~80 LOC, post #2 UI + Owner Step 4 ack)

per Owner 字面 invariant: broker self-fill 违反 (K减). 采 P2P order book matcher (B):
- BUY user 出价 ≥ active SELL offer 价 → 自动 match (broker 撮合, 不 self-fill)
- escrow custody 模式 broker maker, 真背后 user economic maker
- broker net Δ=0 (zero-sum)
- 加 quote "自定价" prompt (user 出价 vs mid market)
