✏️ CI goes red on a test you never touched, so you click re-run and hope. Nobody on the team can say how often that happens or what it costs.

Your GitHub Actions history already knows. I wrote a prompt that reads it, names the confirmed flakes, and puts an annual dollar figure on the re-runs. Plus the usual Elixir causes to look for.
