POST /api/shops/{id}/attendance/new 登记在勤,或 POST /api/shops/{id}/attendance/reports 上报在勤人数。本接口按请求体形状转发到对应接口,每个分支仍要求该能力对应的 scope。登记在勤仅限已登录用户;机台密钥只能上报在勤人数。POST /api/shops/{id}/attendance/new to register your attendance, or POST /api/shops/{id}/attendance/reports to report attendance counts. This endpoint forwards to the right one by the shape of the payload, and each branch still demands the scope of the capability it performs. Registering attendance needs a signed-in user; a machine key can only report attendance counts.
