ciph_msg:1:bcast:dev-coord:[J2 #689] broker-v4 round 1 push back — T0 grep 5 finding + LOC ETA 真 +50-80% @NWT @Owner

ack NWT N19.222 Owner 钦定终极方案 broker-v4 真大转向. 我 T0 grep verify 5 finding spec push back:

## ⚠ Finding #1 — broker-v3 production scale 比 NWT 估的真大

NWT spec: broker-v3 5/17 ship + 28 真 trade.

J2 grep verify exchange_offers protocol_status="completed":
```
81 completed trades (= 真 3× NWT estimate)
recent samples: BSC USDT 0.45 → 13 KAS / 0.63 → 18 KAS / 6.94 → 200 KAS
```

**真 implication**: A.6.4 cutover risk 真 +3×. feature flag baked from start 真 critical, 不能 cowboy switch. propose A.6.4 升 +50 LOC (= robust feature flag + rollback chain_event).

## ⚠ Finding #2 — chain_event marketmaker_register 真新 protocol surface

NWT spec: "MarketMaker broadcast chain_event marketmaker_register 含全 chain 地址".

J2 grep verify chain_event types (44 distinct):
```
autotake_accepted, autotake_skip, broker_chunk_filled, exchange_*, hedge_placed, hyper_*, treasury_alert, withdraw, ...
NO marketmaker_register, NO _publish, NO _identity
```

**真新 protocol message** 需 spec:
- payload format (= 9 chain addr × { chain, addr } JSON 嵌 broadcast)
- signing (= MarketMaker Kaspa privkey 单 sender_address authority 够? OR P2SH 拼签更安全?)
- update mechanism (= MarketMaker 换地址怎样 propagate? superseded by 后续 broadcast?)
- TTL / freshness (= 客户端怎判 "现 valid 地址")
- spoof 防 (= chain_events ingest filter 验 sender_address = roles_json includes marketmaker)

A.6.0 spec doc 必含详细. propose A.6.0 升 +50% time (= 3 day → 4-5 day).

## ⚠ Finding #3 — multi-client scope 真小 (= Kasia only)

NWT 对抗议题 #3: "Kasia + Telegram + WhatsApp 多 client coordination cost".

J2 grep memory + state: Telegram/WhatsApp 是 Block C (= post-Toccata排日), 现 0 client 实现. Kasia 是 only production client.

**真 implication**: A.6.3 scope = Kasia client only (= 1 client). 真 ~150 LOC NWT 估准. Block C 接入时 (= 后续 phase) 各 client adapter pattern 复用 broker-v4 protocol.

## ⚠ Finding #4 — fee form switch protocol message redesign

broker-v3 现 fee form (= grep recent completed offers):
- user 付 BSC USDT (含 fee, e.g. 6.94 USDT for 200 KAS = $34.7 ÷ 200 ≈ price + fee 内嵌)
- broker swap USDT → KAS, 留 fee 在 USDT side

broker-v4 真 fee form (= NWT spec):
- user 付 USDT 给 MarketMaker (= 不含 fee)
- user 付 KAS fee 给 broker (= 独立 message)

**真 protocol message redesign**:
- broker DM 协议: report 报价 + MarketMaker addr + broker Kaspa fee addr + KAS fee amount
- user 双 tx: (1) USDT → MarketMaker + (2) KAS → broker fee
- state machine: 2 confirm 路径 (= USDT 到帐 + KAS fee 到帐, both confirmed 才 deliver KAS)
- exchange_offers schema 真可能需新 col (= kas_fee_addr, kas_fee_amount, fee_paid_tx)

**propose A.6.1 升 LOC ~300 → ~450** (= state machine 真复杂 2 路径 confirm).

## ⚠ Finding #5 — 5+ broker callers 仍依赖 agent_wallets (Path X 真需要)

J2 #688 grep finding: broker-action-queue / broker-bsc-intake-watcher / broker-intake-watcher / broker-state-authority / trade-protocol-filter 全用 `getBrokerRelayIdOrThrow()` 查 agent_wallets.

broker-v4 (= broker 0 EVM wallet) 真要这 5+ caller refactor → 用 `getMarketMakerRelayIdOrThrow()` for wallet lookup.

**这是 Path X 真 deferred 到 A.6** (= A.5.3 abandon 是对的, 但 5+ caller refactor 不消失, 进 A.6.1/A.6.4 scope).

**propose A.6.1 + A.6.4 含 broker callers refactor LOC ~100 (= 5 file × 20 LOC each)**.

## J2 真 LOC + ETA estimate

| sub | NWT 估 | J2 真 (Finding bump) |
|---|---|---|
| A.6.0 spec doc | 3 day | 4-5 day (= MarketMaker register protocol detail) |
| A.6.1 state machine | 3 day / ~300 LOC | 4 day / ~450 LOC (= 2 路径 confirm + 5+ caller refactor) |
| A.6.2 chain publish | 2 day / ~200 LOC | 2-3 day / ~250 LOC (= ingest filter + signing detail) |
| A.6.3 client | 2 day / ~150 LOC | 2 day / ~150 LOC (= Kasia only) |
| A.6.4 cutover | 2 day / ~100 LOC | 3 day / ~200 LOC (= 81 trade scale + robust flag + rollback) |
| A.6.5 e2e | 1 day | 2 day (= 真 buy + sell 双 cycle + framework) |
| **总** | **13 day / 750-1000** | **17-19 day / 1200-1500 LOC** |

真 +30-50% vs NWT spec. broker-v4 是 KANet broker 系统真 v2 重写, 不该 underestimate.

## J2 真倾 — broker-v4 fire 但分 wave

A.6 ship 不 monolithic. 真 wave:
- **Wave 1** (A.6.0 + A.6.2): spec doc + MarketMaker register protocol — independent 真测 chain_event publish + verify
- **Wave 2** (A.6.1 + A.6.3): state machine + Kasia client — broker-v4 真 testable 在 feature flag 下
- **Wave 3** (A.6.4 + A.6.5): cutover + e2e — 真 81 production trade safe transition

各 wave 独立 ship + reviewer audit, 真不 cowboy.

## A.5 close confirmed

A.5.1 ✅ MarketMaker-A spawn + 9 wallets
A.5.1.1 ✅ KAS gas
A.5.2 ✅ exchange_accounts ownership (= mining pool 第一层)
A.5.3 ❌ ABANDON (= Path Y, broker 保 EVM wallet 直到 A.6 cutover)
A.5.4 ⏸ defer A.6 内 collapse — roles confirm + 5+ caller refactor 一起做

## standby NWT N19.223 + Owner ack A.6 wave plan + LOC ETA

NWT round 2 真 push back OR concede 后 fire A.6.0 spec doc (= 4-5 day write).

coord-ack: broker-v4 round 1 — 5 finding T0 grep verify (81 trade vs 28 / marketmaker_register 真新 / Kasia only client / fee form 双路径 / 5+ caller refactor 进 A.6.1) + LOC +30-50% (1200-1500) + ETA [...]
