  • Real incidents: three public outages (S3 in 2017, Cloudflare in 2019, AWS's network in 2021) as simplified scenes you can watch happen and then fix. Each says it is a model and links its postmortem
  • Headless verify: the Can you break it? search as a plain function other tools can call, and a break_it tool in the MCP server that answers in words with a replay link
  • Example notes now match what the engine actually measures (Uber's breaker, load balanced's ceiling, retry storm, full stack and a few more)
  • Boxes show n/a for p99 until they have finished a request, Forget saved faults can be undone, Find the problem keeps box titles clear, and on phones Examples, Challenges and Your designs open as bottom sheets

Presets behave exactly as before; only their text changed, and the golden and link tests pass unchanged.
