How this stays current. This file is the roadmap — no spreadsheet, no PM tool. Updates flow through the working conversation: drop in a transcript or a dependency update, and a refreshed version of this page comes back with a new entry in the version history. Every prior plan stays embedded — use the Plan version picker to see the board exactly as it stood on any date, and What changed for the delta.
Publishing. Replace index.html in the repo with the new file and push — the host redeploys. History is carried inside the file, so old deploys are never needed.
