- rewards: 激励视频实发改按 calculate_ad_reward_coin(eCPM, 当日第N次) 公式;AD_REWARD_COIN/MAX_AD_REWARD_COIN 降为历史兼容口径;新增 SIGNIN_BOOST_COIN=2000

- 签到膨胀: Day1-13 看完激励视频额外发固定金币、Day14 不允许 (signin.py / signin-boost)

- ad_session_id 幂等: ad_ecpm/ad_reward/ad_feed_reward 记录加 ad_session_id 列 + 唯一索引(新迁移 coin_reward_phase2 / ad_feed_reward_session)

- ad.py + schemas + repositories: ecpm-report / feed-reward / reward-status / test-grant 改造;config_schema 增 signin_boost_coin;admin stats overview 补充

- 同步 docs/api + docs/database + docs/integrations/pangle 及 tests(test_ad_reward / test_welfare)

 ## 说明
 客户端在广告**展示后**(`onAdShow` 读 `getShowEcpm()`)调用,把本次展示的 eCPM 落库做**内部收益统计/对账**。
 
-- **best-effort**:客户端 fire-and-forget,丢一两条不影响业务;穿山甲后台报表是结算权威兜底。
+- 普通激励视频发奖会先用 S2S 回调自带 `ecpm`;若缺失,再按 `ad_session_id` 读取本接口上报的 eCPM;两边都没有则不发并记录异常。
+- **best-effort**:客户端 fire-and-forget,但普通激励视频若 S2S 缺 eCPM,这条上报会成为发奖依据。
 - 落 `ad_ecpm_record` 表,`report_date` 用北京时间当天,供「按用户/按天聚合」对账。
 - **与发奖是两条独立流**:发奖走 [ad-pangle-callback](./ad-pangle-callback.md)(穿山甲 S2S,有 `trans_id`、无 ecpm),本接口客户端上报(有 ecpm、无 `trans_id`)。两者无公共键,**不逐条一一对应**,只做按用户/按天聚合口径。
 - eCPM 是**每千次展示预估**,单条展示预估收益 ≈ `ecpm / 1000`,且为客户端预估口径,非最终结算。
