How we grow a fix

  1. 1 Break it first We reproduce the problem on our own droplet behind a Cloudflare zone we control.
  2. 2 Measure before and after Every guide shows the result we measured, with versions and the date.
  3. 3 Show how to undo it Each fix has a check that it worked and a way back.
  4. 4 Re-run when it changes When a vendor changes something, we test again and log it in the guide.
