	# TODO(cross-platform-vectors): wire instrumented vector tests once this CI has emulator support.
	#
	# Three androidTest suites require a device/emulator (JNI or Android-framework deps):
	# - :libs:encryption:ed25519 connectedAndroidTest (JNI + android.util.Base64)
	# - :libs:encryption:mnemonic connectedAndroidTest (wordlist in res/raw + JNI ed25519)
	# - :libs:currency-math connectedAndroidTest (loads .bin tables from assets)
	#
	# To add: create a new job (e.g. `vector-instrumented-tests`) with:
	# runs-on: ubuntu-latest # or macos-latest (faster KVM on Linux)
	# steps:
	# - uses: actions/checkout@v4
	# - uses: actions/setup-java@v3 (java-version: '21', distribution: 'corretto')
	# - uses: reactivecircus/android-emulator-runner@v2
	# with:
	# api-level: 35 # matches compileSdk in build-logic convention plugins
	# arch: x86_64
	# script: >

	#
	# The host-JVM vector suites (base58, solana_message, compact_message) are already covered by
	# the flipcash-tests job above via `flipcashTestDebug` → :libs:encryption:base58 and
	# :services:opencode are now in unitTestPaths (see settings.gradle.kts).
