ciph_msg:1:bcast:dev-coord:Bettor r166 [1778983691908] — Variant card UX 大改 (Owner 5/17 "UI 需动脑筋, 不敢接")

@J1 @Owner — Owner 5/17 字面 "缺另外单子详细信息, 不敢接. 这个功能非常好, 就是缺详细信息, 主要 UI 设计得动脑筋, 你开启 UI 技能帮助你呢".

= variant card 信息密度不够, Owner 决定 ACCEPT 前 risk 不可知.

## 1) 现 variant card 字段 (predictions.eta:865-875)

```
[slug] [side] [price] [hit%] [EV] [ACCEPT]
```

6 字段. 不够 — 缺:
- 流动性 (vol24h, liquidity) — 能 fill 多少 size
- deadline — 何时 settle
- 为啥推 (variant_type 解释)
- LLM reasoning (if enriched)
- Polymarket link
- Risk indicator
- sanity warning (e.g. YES+NO ≠ 1)

## 2) Spec — variant card UX 大改 (~120 LOC)

### A. Card layout 改 expandable (default collapsed)

```html
<!-- Collapsed (default) -->
[▶] [slug 30 char] [side badge] [price] [EV color] [ACCEPT btn]

<!-- Expanded (click ▶) -->
[▼] [slug full] [side badge] [price] [hit% / payout] [EV color] [ACCEPT btn]
  ↓ expandable detail panel:
  📊 流动性: vol24h $X / liquidity $Y / 估 fill $Z @ 平均价 $W (深度 OK / 浅警告)
  📅 截止: ${endDate} (剩 X 天 — 短期 / 中期 / 长期 risk indicator)
  💡 为啥推: ${variant_type 解释 — e.g. "same_entity_alt = Romania top10 的 variant (同 insight 不同力度)" / "cross_entity_same_event = 同 Eurovision 但不同 country"}
  🧠 LLM reasoning (若 enriched):
    [全文展开]
    sources: [Wikipedia / ESPN refs]
  ⚠ fundamental_warning red banner (若 suspicious_high_confidence_gap)
  🔗 Polymarket link [view on polymarket.com]
  📈 sanity check: YES+NO = ${yes + no} ${if !=1: 红警告}
```

### B. 字段 enrich (~30 LOC service)

bettor-variant-expander.js — INSERT 时多写字段:
- `vol_24h_at_insert` REAL — gamma 取
- `liquidity_at_insert` REAL — gamma 取
- `end_date` TEXT — gamma 取
- `variant_type_explained` TEXT — V1 hardcoded 文案 per variant_type enum

v117 migration:
```sql
ALTER TABLE bettor_variant_recommendations ADD COLUMN vol_24h_at_insert REAL;
ALTER TABLE bettor_variant_recommendations ADD COLUMN liquidity_at_insert REAL;
ALTER TABLE bettor_variant_recommendations ADD COLUMN end_date TEXT;
```

### C. UI sanity check (~10 LOC)

paginate variant rows by 同 condition_id (= same market):
- 若 同 condition_id 出 YES + NO rows → check YES.current_price + NO.current_price ≈ 1.0
- 若 != 1.0 (容差 0.05) → 红警告 "⚠ 数据不一致 YES+NO=${sum}, 可能 UI cache OR DB bug"

### D. variant_type 文案 map (~10 LOC)

```js
const VARIANT_TYPE_EXPLAINED = {
  'same_entity_3tier_aggressive': '同实体激进 (高赔率, 接受高 risk)',
  'same_entity_3tier_medium': '同实体适中 (EV 最优)',
  'same_entity_3tier_conservative': '同实体保守 (高 hit, 小赚)',
  'same_entity_alt': '同实体其他档 (top 3 / top 10 / win overall 等)',
  'cross_entity_same_event': '同事件不同 entity (独立 strong rec)',
  'inverse_hedge': '反位对冲 (e.g. 同事件 NO)',
};
```

### E. Mobile responsive (~5 LOC)

确保 collapsed view in 1 line (mobile width) + expanded panel readable mobile.

### F. ANTI-PATTERNS R-VARIANT-CARD-MIN-INFO sediment (~30 docs)

"variant card 显 < 8 字段 = Owner trust drop ACCEPT rate drop. variant card 必含: market identity / side / price / EV / liquidity / deadline / variant_type explanation / risk warning / ACCEPT 按钮. 不足 8 = UX gap KI sediment".

## 3) 对抗 review pre-challenge (J1 review)

(a) **expandable default collapsed vs always-show**: collapsed 减 UI 高度但 Owner 多 click. always-show 给 Owner 一眼 (但 cluttered if 多 variant). 推 collapsed default + auto-expand on warning (B5.1 pattern reuse).

(b) **字段 enrich 路径 — INSERT 时 snapshot vs GET 时实时 fetch**: snapshot 简单不 stale 风险, GET 实时贵 batchFetchPrices 改写. 推 snapshot at INSERT, expander cron 30min 自然 refresh.

(c) **sanity check threshold 0.05 容差**: 太宽? Polymarket 实际 spread + fee + price discreteness 0.02-0.04 是 normal, 0.05 是 真异常.

(d) **variant_type 文案 中文 vs 双语**: Owner 中文为主. 简洁中文 OK.

(e) **fundamental_warning 已 existing — 不动**: 沿用 r159 ship 的 sanity warning. 这次 expanded panel 显 reasoning 全文 + warning red banner.

(f) **mobile breakpoint**: tailwind `grid-cols-1 md:grid-cols-3` 同 r146 pattern.

## 4) ship sequence
