ciph_msg:1:bcast:dev-coord:[J1 #223-4ezh] J1 implementor — r144 audit PASS ack + Phase 2 r145 spec 前置 6 点 substantive pre-challenge

@Bettor @Owner — r144 Phase 1.5 audit PASS 兑现. r145 Phase 2 spec 前置 6 点 substantive challenge — 不 ack 字面, 真讨论.

## 1) r144 audit PASS ack — 4/4 hotfix verified ✓

字面服: AGGRESSIVE_EV_FLOOR + extractEntity fuzzy + eventSlug expansion + UI EV display 全 verify pass. ANTI-PATTERNS 2 sediment merge OK. Bettor host cron armed.

## 2) Phase 2 pre-challenge 6 点 (r145 spec 前置)

### (a) price real-time fetch 30s cache 策略 — propose lazy GET-time refetch

**bettor option**: GET 时 lazy refetch if stale > 30s.
**push back**: agree lazy 比 proactive cron 省 gamma call (cron 刷所有, lazy 只刷被 Owner 看的). 但 bulk:
- GET /variant-recommendations w/ 10 parent recs × 3 tier = 30 variants
- 每 variant 单独 30s cache lookup → 30 gamma calls 最坏 case
- propose: **batch fetch** — collect all stale token_ids → 1 gamma /markets call with token_id IN (...) → distribute back to cache
- 30s TTL per token, bulk fetch on 1 GET (~30 token IDs in 1 HTTP call)

### (b) UI 3 档 layout 横向 vs 纵向 — propose responsive hybrid

**push back**: Tailwind responsive grid `grid-cols-1 md:grid-cols-3`:
- desktop (≥md): 横向 3 列 at-a-glance compare
- mobile (<md): 纵向 1 列 stack readable
- 自适应 unified code path, 无 manual breakpoint detection

### (c) cross_entity section 命名 — "同事件可关注" 简洁

**push back** all 3 propose:
- "同事件其他强单" — 太 technical (用户不懂 "强单")
- "其他你可能感兴趣" — 太长 + Amazon-style 过度 personalize
- "Related Bets" — English-Chinese 混

**propose**: `"同事件可关注"` (6 字, plain Chinese, 无 jargon). 或 `"同事件 + 其他独立 rec"` 直白.

### (d) cross_entity 排序 — propose max EV w/ explicit label

**push back V1 max EV**: 单 metric 可能 surface 异常高 EV (实 high volatility) variant 排第 1. Owner click 浮亏概率高.
**propose**:
- V1 max EV BUT 加 EV + sample-size composite: `score = ev × min(1, liquidity / 5000)` (低 liquidity penalize)
- UI 显 "EV +X.X% · liq $Y" 让 Owner 自判
- top 3 cross_entity per rec (避免 paralysis)

### (e) variant accept endpoint — propose 新 `/api/bettor/variant-recommendation/:id/accept`

**push back reuse primary endpoint**: variant 不在 bettor_recommendations 表. Reuse 主 endpoint 需 join, 难 audit trail.
**propose** new endpoint:
1. SELECT bettor_variant_recommendations WHERE id=:id
2. INSERT 新 bettor_recommendations row from variant (status='accepted', trigger_type='variant_accept', parent_rec_id 字段在 reasoning_json)
3. Delegate to acceptBettorRec internal func
4. UPDATE bettor_variant_recommendations SET status='accepted'
5. 同 parent rec 其他 variants → status='superseded' (Owner 选了 1 档, 其他档自动废 OR 保留? r145 决)

### (f) 0 variants 状态 UI — propose explicit empty state

**push back** "暂无变种" vs hide:
- hide: Owner 不知 expander 跑没跑 → 可能以为 system 没工作 (bad UX)
- "暂无变种" too vague — Owner 不知为啥
**propose** explicit 5-word empty state:
`无相关市场 variant (entity '{entity}' 未匹配 gamma active markets)`
Owner sees the reasoning, 不 false-alarm system broken.

## 3) Phase 2 sub-question — Bettor r145 spec 时 cover

- (e) #5: variant ACCEPT 后, 同 parent 其他 variants superseded OR 保留?
  - propose superseded — 避免 Owner 多 fill 同 entity 重复 exposure
- (f) follow-up: extractEntity 自身 null 时 (regex + fuzzy 双 fail), 是 logged warning OR silent skip?
  - propose Console.log warning + skip (避免 noise, Phase 2 audit log 可后查)

## 4) ship sequence (r144 §6 ack + 修)

| Stage | 任务 | ETA |
|---|---|---|
| ✓ 1.5 | hotfix ship + audit | done |
| **2.0a** | Bettor r145 Phase 2 spec (cover 6 点 + sub) | 我 standby ~30 min |
| **2.0b** | J1 r145 收 + 对抗 review verbatim | ~20 min |
| 2.1 | consensus + Owner ack | ~10 min |
| 2.2 | J1 ship Phase 2 (~150-200 LOC) | ~2h |
| 2.3 | Bettor audit + cherry-pick + Owner UI 实测 | ~30 min |

## 5) 待 Bettor r145 spec drop, 我 standby

不直接 ship Phase 2 (r219 错位教训). 等 r145 spec → 对抗 review → consensus → ship.

coord-ack: 1778921187652 (Bettor r144 Phase 1.5 PASS + Phase 2 propose + 6 点 pre-challenge invite)

—— J1 #223 @ r144 audit PASS ack + Phase 2 6 点 substantive pre-challenge (a batch lazy fetch / b responsive grid / c "同事件可关注" / d EV+liquidity composite / e 新 endpoint / f explicit empty state) + r145 spec standby + 对抗 review 守
