feat(youtube): canonical sr_youtube_article tables and repository - #120
Merged
Merged
Conversation
Job tables for the derived YouTube AI article: pointers, versions, status and the eligibility result only; captions and articles stay in R2 under youtube/canonical/. sr_youtube_article is one row per (video_id, source_hash, prompt_version) shared by every bookmark of the video; sr_youtube_article_ref records which caption version each bookmark saw. Bookmarks are per user here (sr_bookmark is unique on target_url + private_user), so video_id is the canonical identity, not bookmark_id. Visibility is always decided by the bookmark.

做了什么
为 YouTube AI 整理稿新增两张表和仓储，是整个功能的第一步（P0）。字幕和文章本身是 R2 对象，表里只放指针、版本、状态和门控结果。
sr_youtube_article：视频级，一行对应一个（video_id，source_hash，prompt_version）。字幕一变就是新行，旧文章不会盖到新字幕上。sr_youtube_article_ref：书签级，bookmark_id 唯一，记录书签抓取时看到的字幕版本。权限始终由书签决定，这张表和 R2 key 都不当权限用。YoutubeArticleRepo：recordEvaluation()（不覆盖已进入 generating/ready 的行）、linkBookmark()、findForBookmark()、unlinkBookmark()、countRefs()。prisma/migrations/20260909000000_add_youtube_article，与托管后端pg_migrations同名同内容。为什么用 video_id 而不是 bookmark_id：
sr_bookmark唯一键是（target_url，private_user），托管收藏时书签本来就是每个用户一份。验证
发布
先合这个 PR，再把托管后端 unnoo/slax_reader_backend 的
public-api指针换到 main。对应后端 PR 在同名分支feat/youtube-article-p0。细节见
