page.cavu.forge.fact

Something true about an entity for a stretch of the story's timeline: its name, an age, where someone lives, who they're married to — in whatever terms the project defines (page.cavu.forge.attribute). Entities are bare identities; every attribute, the name included, is a fact. Nothing is assumed static. Time is the timeline's order, not dates: a fact holds from its `from` event (inclusive; absent = from the start) until its `until` event (exclusive; absent = onward). Unless the attribute is defined as multi-valued, the holding fact with the latest start wins, so a later fact supersedes an earlier one without either being edited. Ages are stated, never computed — there is no calendar to compute them from.
