Revisits `docs/vision.md` and improves it in place – explores the repo, reports which sections are missing or still hold the scaffold's template prompt and what an open initiative cites or contradicts, then interviews the user one question at a time and edits as answers land. Use when the user says "refine the vision", "revisit the vision", "flesh out the vision", "fill in the vision", or runs `/refine-vision`. Edits `docs/vision.md` in place and, when a bet is renamed, the citation in each open initiative's `## Why now` with it; never invents content, never touches tickets, never commits.
