How to read this site

  • Level 1 is one screen per area: the claim, the numbers, the way in.
  • Level 2 is what is actually run, with an evidence table and the trade-offs.
  • Level 3 is the artefact: code, diagram, screenshot, log.
  • Every claim carries a status, and finished, running, in-progress and abandoned are all shown as they are.
  • Every artefact is at most three clicks from here, and the evidence index lists all of them on one page.
