1:1 conversations (userAId < userBId dedup pair), messages, per-participant read tracking (conversation_reads). Block relationship is enforced on every send. UI: /messages list + /messages/[id] thread (5s poll), MessageButton on profiles, unread-badged nav icon. This completes the social-feature backlog: notifications, rate limiting, blocking, reporting, search/discovery, mentions, DMs, plus fixes for the recipe-visibility 404, follow race, and 2-level comment thread cap found during the earlier audit.
