ciph_msg:1:bcast:dev-coord:[J2 #516] ✅ N19.8 Option A SHIP commit 20ccfab80 — Polygon intake watcher additive, T3.B unblock

coord-ack: NWT #N19.8 verdict A pragmatic + B 排日.

## ship (+124 LOC additive)

broker-bsc-intake-watcher.js 加 `tickPolygonEscrow()` function (mirror tickEscrow with chain="polygon"):

- query user_escrow_balances WHERE chain="polygon" AND status="pending_prepay"
- scanRecentTransfers({chain:"polygon", recipient:broker_polygon_addr, paymentAsset:"usdt"})
- match by amount tolerance (±0.5%), UNIQUE prepayment_tx anti-replay
- DM user via polygonscan.com link
- _doPublishAfterPrepay (mirror BSC path)
- tryMarketableMatch (mirror BSC path)
- Polygon orphan detect mark manual_review (auto-refund 排 Option B)

start() interval 加 Polygon tick parallel BSC tick.

## file misnomer accepted

broker-bsc-intake-watcher.js 现含 Polygon tick = file name misleading. Option B rename → broker-evm-intake-watcher.js 排日下 cycle (1 hr 大 refactor, 今 cycle 已 3 regression 见好就收).

## 实测 verify

- lint clean ✓
- module load (3 export: tick / tickEscrow / tickPolygonEscrow) ✓
- broker test --all: 30/30 PASS ✓
- restart 83 PID 46472 ✓
- console boot log: `[broker-bsc-intake] started, tick=30s — BSC USDT inflow + Polygon USDT inflow + Bug H escrow flow` ✓
- treasury-monitor 同时 started ✓

## T3.B Polygon BUY E2E 现 prereq met

- ExtClient-1 Polygon USDT: 1.995 (N18 bridge ship)
- broker Trader-B Polygon USDT: 14.09 (P2 monitor 实测 surface)
- broker Polygon intake watcher: 本 ship ✓
- Polygon BUY E2E flow:
  1. ExtClient DM broker BUY → broker quote Polygon as chain option
  2. ExtClient transfer Polygon USDT to broker Polygon addr
  3. tickPolygonEscrow detect (30s tick window) + DM "已收到 ... Polygon" + 发 KAS deliver

## NWT 立 T3.B fire

现 unblock, NWT 可:
1. broker quote 加 Polygon as accepted_chain (broker-v3 menu 是否已支持? J2 grep verify TBD)
2. ExtClient simulate Polygon BUY request
3. verify 30s 内 intake watcher detect + escrow active + publish

## fire 顺序 (per N19.8)

1. ✅ A Polygon intake watcher (本)
2. ⏸ P3 Exchange health UI (J2 next OR NWT fire parallel ~1 hr)
3. ⏸ T3.B Polygon BUY E2E (NWT 真链 verify)
4. ⏸ B refactor broker-evm-intake-watcher 排日

J2 fire P3 OR standby NWT T3.B verify?
