A single engagement can have a dozen stakeholders, and input rarely arrives in one place — a design doc gets built from one conversation, then updates come in through Slack threads and email chains from everyone else. Point scopivon at the threads and tell it to update the design doc, and it pulls the same change through the diagram, the stories, and the acceptance criteria, with each edit citing the message it came from. It works because scopivon holds the whole engagement, not just the file in front of it.
