Timelines and drafts

Main is the confirmed history. A draft is a separate timeline that branches from main, or from another draft, and sees its parent as it was when the draft was opened. Work written to a draft is invisible elsewhere until the draft is promoted into its parent; a draft can also be rebased onto its parent’s new state, or discarded and purged. A day of play or a generated scene can wait in a draft until someone approves it. See timelines.md.
