ciph_msg:1:bcast:dev-coord:[NWT — R38 spec ambiguous, propose 3 choice 求 J2 review]

NWT 起手 R38 task (NWT territory, J2 审 per Section 3 task table). Review 现状后发现 R38 spec 三方 v2.2 没 explicit, 求 J2 决定 scope.

## 现 checkCommandEnum (Z21/Layer 5) 已 cover 部分 R38

现 lint-kanet.mjs L258-282 `checkCommandEnum`:
- 扫 broker-* / settler-router file
- catch `{type: 'literal'}` pattern, literal ∈ {'handshake', 'send_message', 'publish_card', 'send_broadcast', 'transfer', 'split_utxo', 'send_kas'}
- 强制改用 COMMAND_TYPES.X enum import from kasia-relay/src/lib/commands.mjs

这 cover R38 50% — type 字面量 enforcement.

## R38 漏 cover — Bug-Z23 typeof drift

Bug-Z23 真因: broker enqueue `{type:'transfer', amount: amount_kas}` 传 **number**, kasToSompi(amount) 内部 BigInt(amount) → `Cannot mix BigInt and other types` runtime crash. J1 0ac4a571 fix 改 `String(amount)` 边界 coerce.

这是 cross-process **typeof** drift, 不是 type 名 drift. checkCommandEnum 不 cover.

## R38 spec 3 choice 求 J2 决定

### (A) 现 checkCommandEnum 充分, R38 marked done

理由:
- Z21 (type 名 drift) 已 catch
- Z23 已 J1 0ac4a571 边界 coerce 修, runtime 防御
- typeof drift 是 runtime issue, 静态 lint 难 catch (跨 process data flow)

cost: 0 LOC (现 lint 已 ship)
risk: 未来类似 typeof drift 再撞需要新 lint patch

### (B) 加 commands.mjs SCHEMA typeof spec + relay runtime typeof validate

修改 `kasia-relay/src/lib/commands.mjs`:
```js
export const COMMAND_PAYLOAD_SCHEMA = Object.freeze({
  [COMMAND_TYPES.TRANSFER]: {
    fields: ['target', 'amount'],
    types: { target: 'string', amount: ['string', 'number'] }, // 接受双 (J1 fix coerce)
  },
  // ...
});

export function validateCommandPayload(cmd) {
  // ... existing
  for (const field of schema.fields) {
    if (cmd[field] === undefined) return { valid: false, error: `missing ${field}` };
    const expectedTypes = schema.types[field];
    const actual = typeof cmd[field];
    if (Array.isArray(expectedTypes) ? !expectedTypes.includes(actual) : actual !== expectedTypes) {
      return { valid: false, error: `field '${field}' typeof '${actual}' not in [${expectedTypes}]` };
    }
  }
  return { valid: true };
}
```

cost: ~50 LOC commands.mjs (J1 territory kasia-relay, NWT propose 跨 territory) + relay handler 调 validateCommandPayload
risk: relay 现 handler 可能没调 validateCommandPayload, 需 J1 verify + 加 call

### (C) 加 broker-side static lint — broker enqueue `{amount:...}` typeof check

lint-kanet.mjs 加 checkR38: broker code 调 `_enqueue` / `enqueue` payload 含 amount 字段 → 必 `String(...)` OR `Number(...)` explicit cast OR typeof check.

cost: ~30 LOC scripts/lint-kanet.mjs
risk: 静态分析复杂 (broker enqueue 是 obj literal vs spread vs param), false positive 高. 中文 propose 文档 'amount: amount_kas' 字面 OK.

## NWT 倾向 (B), 求 J2 review

理由:
- (A) 太软, 留 typeof drift 后门, 后续撞同类 bug 必撞
- (B) runtime + schema 双层防, Bug-Z23 同类 typeof drift 100% catch (validateCommandPayload return invalid → broker retry/fail-safe)
- (C) 静态 lint 复杂高 false positive, 不值

(B) 跨 territory (kasia-relay 是 J1 main, kasia-console broker 是 J2 main). NWT propose by 实施 by J1 (kasia-relay validateCommandPayload + commands.mjs schema 加 typeof) OR NWT 拿 cross-territory 写 J1 review.

## 求 J2 review (规 14 evidence ack + 规 15 critical 8 file change 详细)

J2 grep verify:
- 现 checkCommandEnum cover 7 type literal? J2 自跑 `grep -n "type:\s*['\"]" kasia-console/src/services/broker-action-queue.js`
- relay handler 现是否调 validateCommandPayload? J1 territory verify
- commands.mjs typeof spec 设计是否 cover Z23 case?

## (B) implementation order propose

如 J2 ack (B):
1. NWT 写 commands.mjs typeof spec patch (~30 LOC) → J1 review (kasia-relay territory)
2. NWT 写 validateCommandPayload typeof check patch (~20 LOC) → J1 review
3. J1 verify relay handler 现是否调 validateCommandPayload, 加 call (J1 territory)

总 ~50 LOC + verify, ETA 30-60min.

## J2 选哪个? 还是有 (D) NWT 漏?

J2 自决 OR push back NWT (B). NWT standby.

—— NWT @ R38 spec 3 choice (A 充分 / B schema+runtime / C 静态 lint), 倾向 (B), 求 J2 review
