为什么：原 controller handler 在 HTTP 层同时承担了 4 项 usecase 职责 （多源拼装、错误降级策略、limit 硬编码、响应结构组装），违反了 "controller 只做参数解析 + 调用 + 序列化" 的边界。等后续给衍生品加 缓存 / taker volume / 数据质量字段时，HTTP 层会持续变厚。 改动： - 新增 internal/usecase/market_query.go: MarketQueryUsecase.GetDerivatives() 并发拉 current funding/OI + 串行查历史 + 错误聚合为 warnings 返回 - /derivatives handler 退化到 4 行；MarketDeps / restapi.Deps 同步收窄 - /klines 保持直查 KlineRepo（thin query，G11 例外） - 新增 G11 守卫：grep "FundingRepo|OIRepo|LSRepo|TakerRepo" internal/controller 破坏性 API 变更（/derivatives 响应）： - 删除 funding.error / openInterest.error - 新增顶层 warnings: []string 顶层 symbol / funding / openInterest / longShortRatio / takerBuySellVolume 保持。 harness 同步： - AGENTS.md §6 加 G11 grep - ai/project-map.md 加 market_query.go + /derivatives 数据流分支 - ai/task-templates.md T6 加"破坏性变体"分支（本次重构暴露了原假设过严） - ai/harness-health.md W1 记一次轻量验证 + 守卫数 10→11 验收: go build / go vet / G6 grep / G11 grep 全绿。
