 - YouTube uses `/streams/native-manifest` first, then fallback to `/streams/manifest` on `422`
 - NicoNico can return `422` on `/streams/manifest`; expected for non-DASH cases
 - `GET /search-history` supports backend pagination: `page` and `limit`, total from `X-Total-Count`
-- `settings.recommendationPersonalizationEnabled=false` disables recommendation event/feedback personalization while keeping Home recommendations available
-- Shorts recommendations can emit `short_skip` with optional `watchDurationMs` for skip-depth signals
+- Home and Shorts recommendations are fetched without client event reporting
 
 ## Recommendation and Privacy Flow
 
-- Frontend stores user preference through `PUT /settings` (`recommendationPersonalizationEnabled`).
-- Recommendation events are posted to `/recommendations/events` with optional fields such as `watchRatio` and `watchDurationMs`.
 - Home feed requests call `/recommendations/home` with `intent` (currently default `auto`).
+- Shorts feed requests call `/recommendations/shorts` with `intent` (currently default `auto`).
 - Optional offline quality metrics are available via `/recommendations/home/metrics`.
