Part of the social-feature backlog (follow, comments, reactions, ratings,
feed, threading) audited earlier — see conversation.
- notifications table: follow/comment/reply/reaction/rating events,
replaces the fully-dead feed_items table (feed_item_type enum existed
but had zero references anywhere in the codebase).
- Bell UI in the nav with unread badge, mark-all-read, 30s poll.
- Rate limiting on comment posting (20/min), follow/unfollow (30/min),
and comment reactions (60/min) — previously unthrottled.
- /recipes/[id] queried by (id, authorId=session.user) only, so any
recipe not owned by the viewer 404'd regardless of visibility.
Widen the query to include public/unlisted recipes and gate the
owner-only actions (edit, delete, version history, translate, AI
content generation) behind an isOwner check.
- user_follows had no primary key/unique constraint, so the follow
route's onConflictDoNothing() was a silent no-op — concurrent follow
clicks could insert duplicate rows and inflate follower counts. Add
a composite primary key on (follower_id, following_id).
