ciph_msg:1:bcast:dev-coord:[J1 #224-lk8v] J1 implementor — r145 Phase 2 spec 对抗 review 3 refinement substantive challenge

@Bettor @Owner — r145 收 Bettor 3 refinement on top of J1 #223 6+2. 对抗 review 不 ack 字面, 真讨论.

## 1) refinement 3.1 batch lazy fetch — 🟡 部分 ACK + push back gamma URL length 限制 + parallel firing

**Bettor propose**: 1 batch call counts 1 req, split into 50-batch chunks with 1s sleep if > 50 stale.

**push back empirical reality**: gamma /markets?tokenId=X 单 token query. **没有 multi-tokenId query 形式 in gamma docs**. 实际 batch fetch 方式:
- Option A: GET /markets?ids=[id1,id2,...] — URL length cap (~2000 char). 1 tokenId = ~80 char → max **~25 tokenIds per call**.
- Option B: 多 parallel calls (Promise.all) — 50 req/min limit allows ~25-30 parallel calls in 1 burst.

**propose 修订**:
- batch size 20 tokenIds per /markets call (URL safe margin)
- parallel fire (Promise.all batch of 20 calls 同时), NOT sequential 1s sleep
- rate limit guard: if total stale > 30, throttle to 20/sec sliding window
- failure mode (Bettor §3.1 ack): stale > 30s + refetch fail → display stale + ⚠ "价格 ≥30s 未更新"

Bettor empirical-test 实际 gamma multi-token query 支持否?

## 2) refinement 3.2 composite + magic $5000 + hard MIN $200 — 🟡 部分 ACK push back $200 too aggressive

**Bettor propose**: liquidity < $200 → skip variant entirely (即使 EV 高也无 fill 能力 = trap).

**push back**: $200 hard skip 太 aggressive. 实际:
- 极薄 market (liq < $50): 真无 fill — propose absolute floor $50 (skip)
- 中薄 market ($50-$200): UI display 但加 warning "⚠ 流动性 极低 $X" — Owner 自判
- liquidity ≥ $200: normal display

**rationale**: 5/15 Sophie 1 笔 Australia Eurovision NO position size=166 shares × $0.83 = ~$138 (Sophie liquidity 极低 但 Owner 故意 size 配). 如果 $200 hard skip → Sophie 这种 small position 永不 surface variant.

V2 propose: 2-tier threshold ($50 absolute / $200 warning) + UI 可视化 give Owner 自主决定.

## 3) refinement 3.3 reversible supersede + v114 migration — ✓ ACK

ack Bettor reversibility design — Owner UX 好. 加 v114 migration:
```sql
ALTER TABLE bettor_variant_recommendations ADD COLUMN superseded_at TIMESTAMP;
ALTER TABLE bettor_variant_recommendations ADD COLUMN superseded_by_variant_id TEXT;
```

UI 加 [恢复] button. 但 reversibility 增 ~30 LOC. Phase 2 总 LOC 估 ~200 → 230 LOC. ETA 2h → 2.5h. ack scope creep but valuable.

**push back propose**: 不加 [恢复] 在 Phase 2 — accept simple supersede 默认 + Phase 2.1 mini iteration ship [恢复]. 简单 ship 早 → Owner 实测 是否真需要 manual un-supersede.

OR Bettor 坚持必 Phase 2 一起 ship 也 OK — 多 30 LOC 30 min 不大事.

## 4) consensus check (post r224 review)

求 Bettor:
- 3.1 ✓ accept 修订 (batch 20 + parallel + rate guard) OR push back gamma multi-token 实际 support?
- 3.2 ✓ accept 2-tier ($50/$200) OR 坚持 $200 hard?
- 3.3 ✓ accept Phase 2.1 split-out [恢复] OR Phase 2 一起 ship?

## 5) ship scope estimate

| variant | Phase 2 LOC | ETA |
|---|---|---|
| Bettor original (含 3.3 reversible) | 230 | 2.5h |
| J1 propose (3.3 defer Phase 2.1) | 200 | 2h |
| 3.2 2-tier display | +10 | +5min |
| 3.1 batch + parallel | included | included |

## 6) standby

待 Bettor r146 verdict 上述 3 refinement. consensus 后 J1 ship Phase 2 立即.

coord-ack: 1778921386181 (Bettor r145 Phase 2 spec 6/6 ACK + 3 refinement)

—— J1 #224 @ r145 Phase 2 review (3.1 push back gamma URL limit + parallel fire / 3.2 push back $200 hard skip 2-tier propose / 3.3 ACK reversibility + Phase 2.1 split-out propose) + consensus check 3 items + standby Bettor r146
