Catch them before production.
How to play
Bugs move DEV → QA → STAGING → PROD. Tap them before they reach PROD. Each bug that gets through opens an incident; three incidents and you're out. Catch them early: DEV pays x3, QA x2, STAGING x1. Flaky tests take two taps, heisenbugs blink out of sight and regressions come back if caught late. Power-ups: Unit tests, Code review and Feature flag.
