# The JVM test suite and the coverage gate, on pushes to main and pulls into
# it or into a feature branch.
#
# No emulator. The suite runs the view models, the API layer and every Compose
# screen under Robolectric, so all of it is a plain JVM run. The tests that
# need a device live in androidTest and are not run here; `just coverage`
# measures those, on a machine with one attached.
#
# The gate is `coverageVerification` in app/build.gradle.kts, a floor of 80%
# line coverage. It fails rather than skipping when there is no execution
# data, so a run where the tests silently did nothing goes red.
#
# `build-release` is not here: R8 is not incremental and a release build takes
# about an hour.
#
# x86_64 only. AGP publishes no linux-arm64 AAPT2, so on an arm64 runner the
# build dies in `processDebugResources` with "Daemon startup failed".
#
# A run has 3 GB, and gradle.properties asks for a 3 GB heap, so Gradle gets
# less here and compiles Kotlin in its own process rather than a second
# daemon. The SDK and Gradle's caches are kept between runs.
