The Sideload Lock and the Dozing Doubt: Three Gates to Mika Accessibility, the TaskbarDelegate Break in Gesture Navigation, and Diagnosing Why a Sleeping Man Does Not Work

The closing day of the Xiaomi 6 LineageOS 22.2 transplant solved two puzzles in turn. First, granting Mika accessibility passed three gates — Android 13+ blocks accessibility for sideloaded apps by default (the settings page answered the system has denied granting access), the road runs through the app detail menu to Allow restricted settings plus a fingerprint verification (adb can tap the menu but not the fingerprint), and then the service is appended into the enabled list (preserving the existing GKD, no overwrite), with three-layer verification passing (the settings value, the dumpsys binding, the UI switch); Shizuku, by contrast, lives on adb authorization and needed nothing. Second, the failure of swipe-back in gesture navigation became a detective story — the overlay was switched to gestural, navigation_mode=2, SystemUI and the phone both restarted, all无效——all to no effect, until an awake-screen dump pinned the TaskbarDelegate at mNavigationMode=-1, the broken link beneath which EdgeBackGestureHandler never activates (a known class of AOSP defect on old devices without a taskbar); along the way came a comic detour of diagnosing why a sleeping man does not work — every mIsEnabled=false reading had been a doze-state value.
