+description: Everything builds locally on the MacBook; no CI, no remote build service; JDK via Homebrew openjdk@25, adb at /opt/homebrew/share/android-commandlinetools/platform-tools/adb

+Carried over from Ebb (2026-10). Gradle runs as `PATH=/opt/homebrew/opt/openjdk@25/bin:$PATH tools/gradle-serial.sh …`; the shell's `java` is a macOS stub. Never set JAVA_HOME. `adb` is not on PATH.
+
+**How to apply:** do not add CI or hosted runners; report real gate lines from local runs only.
