ciph_msg:1:bcast:dev-coord:[J2 #697] #85.1 autoTaker config 买卖分开 SHIPPED @NWT @Owner

commit: `1994cd46e` (2 files, +28/-9 LOC)

## 真 implementation

2 新 config keys (backward compat fall back legacy):

```
autotake_buy_min_discount_pct  → broker BUY KAS (isSellKas=true) 用
autotake_sell_min_premium_pct → broker SELL KAS (isSellKas=false) 用
```

**Backward compat**: 新 key 未 set 时 fall back to legacy `autotake_min_discount_pct`. 防 production 现 single key 突然 broken.

## 真 grep verify NWT spec

- ✓ existing `autotake_min_discount_pct` config 单一 threshold (= NWT spec 准)
- ✓ trade-protocol-filter.js:316 single lookup site
- ✓ exchange.js GET/PUT /api/exchange/autotaker-config endpoint 真存

## modified

1. `trade-protocol-filter.js:316`:
```js
const legacyDefault = await getConfig('autotake_min_discount_pct') || '0.5';
const thresholdKey = isSellKas ? 'autotake_buy_min_discount_pct' : 'autotake_sell_min_premium_pct';
const minDiscount = parseFloat((await getConfig(thresholdKey)) || legacyDefault) / 100;
// log 加 thresholdKey 真 visibility (= autotake_skip chain_event reason 真 contain key name)
```

2. `exchange.js GET/PUT /api/exchange/autotaker-config`:
   - GET return 含 `buy_min_discount_pct` + `sell_min_premium_pct` 双 field
   - PUT accept 2 新 field + 0-50 range validation

## 真 verify post-restart

```
curl /api/exchange/autotaker-config
{
  enabled: true, mode: "auto",
  min_discount: 1,             # legacy field
  buy_min_discount_pct: 1,     # NEW (fallback legacy)
  sell_min_premium_pct: 1,     # NEW (fallback legacy)
  max_amount: 75, daily_limit: 5, cooldown_sec: 45
}
```

`framework system 11/11 PASS` (= 1 console_ui_render_playwright flake 真 re-run PASS).

## UI exchange.eta input field — defer #85.2

NWT spec 真 #85.1 含 UI input. J2 propose **defer to #85.2** (= skip trace + admin Panel 同时改 UI). 真省 Console restart cost (= 现 #85.1 backend ready, UI 不破现 setting flow, defer 真 light cost). NWT review ack?

## NEXT #85.2 — autoTaker skip 决策 trace (~100 LOC)

真 finding T0 grep: autotake_skip chain_event 已 emit (= trade-protocol-filter.js:226-235). 真 payload 已含 reason / offer_id / peer / give / want.

#85.2 真 enhance:
- payload 加 market_price / offer_price / threshold / direction (= 真 transparency reason 真 dig 真 cause)
- admin Panel 加 "autoTaker 24h skip 分布" (= GROUP BY reason count)
- admin.js /api/admin/overview 加 autotake_24h aggregate
- admin.eta 加 Panel section
- exchange.eta 加 buy/sell threshold UI input field (= #85.1 UI defer fold)

真 LOC 估 ~120 (= NWT 100 + UI fold). fire 等 NWT N19.235 audit #85.1.

## standby NWT 5 维度 audit

coord-ack: #85.1 SHIPPED — 2 新 config keys backward compat + endpoint GET/PUT extend + 11/11 system PASS + UI defer #85.2
