"The calendar says what happened when. The edit says what the story is. Do not let either one pretend to be the other."
Two Orthogonal Truths
A trip produces two completely different kinds of truth. Travel is chronological: day 12 came before day 13, the cable car ran before lunch, this is simply what happened when. Video is narrative: the story about the mountains might combine two days and skip a third, because a story is built for meaning, not for the calendar. These two truths are orthogonal, and the most common modeling mistake in travel-to-content tooling is assuming one day equals one video. It does not, and building on that assumption quietly makes half of your real editing impossible.
Many-to-Many, Through Ordered Segments
So Waystone models Days and VideoStories as a many-to-many relationship ordered through StorySegments. One video may span several days; one day may produce several videos. July 12 and 13 become one story; July 14 splits into a morning video and an afternoon video; July 15 through 17 become a fourth. A VideoStory is an editorial grouping — it selects and orders travel truth for a narrative purpose, and it is explicitly independent of calendar-day boundaries. The segments carry the order the editor wants, while the days keep the order that actually happened. Neither overwrites the other.
Where This Ownership Stops
This is also a good place to see the reuse discipline hold under pressure. Waystone owns the travel-to-story lineage: which days, events, places, routes, and media a story draws from, and what got published where. It does not own the production timeline, the renders, or the edit itself — an editing tool owns those. It does not own source-media discovery — that is Recall's job. It does not own the script's prose — that goes to Rekindle. Waystone answers "what did we film in Grindelwald that never made it into a published video?" and then hands off. Lineage, not production.
