// MISSION BRIEF

Your Mission

A flaky test is worse than a missing one: it burns CI minutes, trains engineers to ignore red, and hides real regressions in its noise. Fighting flake is a discipline with a method, not a mood.

This quiz covers the forensics: root-cause taxonomy, honest retry policy, quarantine mechanics, and the numbers that keep a suite trustworthy. Framework-agnostic by design.
