A raw `adb shell input tap` took no lease, so one session's tap landed in another session's app (2026-09-25). python_pkg.phone_guard classifies every adb call in a Bash command and, as the Claude Code PreToolUse hook, takes the matching phone_lease (one app / real screen / whole phone) or exits 2: key/text input without -d, input on another session's virtual display, or a lease still held elsewhere after 40 s. android_ui gains --display self|<id>: it drives only this session's phone_vd display under that app's lease, and every input carries -d. uiautomator sees display 0 only, so virtual-display trees come from a tiny instrumentation APK (A11yDump.java) built from source without Gradle. Prunes the oldest evidence artifact to stay under the 60-file cap. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WpA6wW2DKiovQADTdjWJoH

|
|
"Reads (logcat, dumpsys, pull, screencap) pass with no lease.",
|

"Input or launches on display 0 take the pkg:__screen__ lease; install/force-stop take that app's lease; reboot, Wi-Fi/airplane/Doze and settings put take the whole-phone lease.",
