// MISSION BRIEF

Your Mission

The release-candidate run just finished across the full device matrix and the dashboard looks like a crime scene. Seven failures, but how many BUGS? Product wants a ship/no-ship call in an hour.

This is the boss fight: cluster failures by root cause, separate app bugs from test bugs from infra noise, and make the release call with reasons. Decisions are weighted; the clustering and the ship call weigh the most.

Release-candidate matrix results

Seven failures. How many distinct root causes, and what are they?

  1. ATwo: Android is broken and iOS is fine
  2. BFour: the API 33+ notification-permission dialog (4 devices), an OOM app bug on low RAM (1), an ambiguous test locator on tablet layout (1), and infra noise, the offline Redmi (1)
  3. COne; the app is broadly broken and the run is unshippable evidence
  4. DSeven; each failing device is its own investigation
Answers, scoring, hints, and the full battle stay sealed.
