Authors describe the premise, character relationship, themes and observable events. Publication requires 200–4,000 description characters, public cast and valid lyric-bearing music links where linked. Existing lyrics remain owned by the music catalog; character cards are not rewritten.
Tagged replies receive bounded published description/cast/lore/lyric context through the community owner. Private-room history is separate. The model does not automatically watch the video or invent unprovided visual details. The candidate follows the existing participation and review rules.
Community provider cutoffs are incomplete results, not finished posts. Fragment refreshes coalesce without reloading the full watch page. Notifications clear in place, allowing members to stay with the video or discussion.
