新手引导视频:运营后台上传 MP4(上限 100MB,魔数校验只认 ISO BMFF), App 端在领券等候浮层前 N 次以引导视频替代广告。新增 guide_video 的 model/schema/repository/router(App 侧 + 后台侧)与播放记录表迁移。 美团券:首页「销量最高 / 智能推荐」两个 tab 改游标分页,配套两条 (city_id, dedup_key, 排序键 DESC) 复合索引,让 Postgres 顺着索引流式 去重,免掉每翻一页重排整城券的开销。美团 CPS client 在 lifespan 预热 并在关闭时释放连接池。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""新手引导视频(领券等候浮层前 N 次替代广告)。
|
|
|
|
路由前缀 `/api/v1/guide-video`(均需 Bearer):
|
|
POST /start 这次浮层放引导视频还是放广告?命中则**当场计次**并下发 play_token
|
|
POST /reward 播完 / 中途关闭都调,按 play_token 幂等发固定金币
|
|
|
|
发币额度以**服务端配置**为准(运营后台可改),客户端只报"播完/关闭",报不了金额,
|
|
所以被破解也刷不到超额金币;次数上限由 guide_video_play 行数(按账号)硬卡。
