 - `hermes-agent/tests/gateway/test_android.py` is a thin mirror that imports the **live `gateway-plugin/` package from this repo** (override with `ANDROID_PLUGIN_DIR`); HERMES_HOME is sandboxed per-test by the conftest. Tests must never touch the real `~/.hermes`.
 - e2e scenarios 3 (reasoning) and 5 (commentary) are model-dependent → SKIP; 11 (push) and 12 (reconnect) are PARTIAL by design.
 - ADB: launch `adb shell am start -n dev.iris.app/.MainActivity`; reset pairing state `adb shell pm clear dev.iris.app`; screenshot `adb exec-out screencap -p > /tmp/shot.png`.
+- ADB UI taps: **never guess tap coordinates from a screenshot** — dump the hierarchy and tap the element's real bounds: `adb shell uiautomator dump` → `adb pull /sdcard/window_dump.xml` → find the node by `text` / `content-desc` / `resource-id` → `adb shell input tap` at the center of its `bounds="[x1,y1][x2,y2]"`. Re-dump after every navigation; if a tap misses, the dump is stale — re-dump, don't nudge coordinates.
 - Gateway logs: `~/.hermes/logs/gateway.log` or `hermes logs --follow`.
