quirks:
  - "Voice remote would not pair after 5 days of uptime (logcat: initate direct connection fail, topology limitation; bond state reason 39). A plain reboot fixed it and pairing then succeeded first try."
  - "Remote buttons arrive over IR (MStar Smart TV IR Receiver) even when the Bluetooth remote is unpaired, so the TV stays controllable while re-pairing; only voice needs Bluetooth."
  - "lockdown.sh: restrict-background and its blacklist only apply on metered networks. On Wi-Fi, dumpsys netpolicy shows Metered ifaces: {}, so 'data blocked' has no effect; RUN_IN_BACKGROUND ignore does apply."
  - "dumbtv home's Settings chip opens com.amazon.tv.launcher/.ui.MainSettingsActivity drawn off the top of the screen, hiding the first row (Inputs, Notifications, Profiles, Account, Network). Issue #77."
  - "adb shell input keyevent HOME while dumbtv home is in front lands on Amazon's home; a short HOME press on the real remote stays on dumbtv home."
  - "com.amazon.tv.launcher is protected (cannot be force-stopped) and stays resident at about 100 MB PSS out of 1.5 GB RAM."
  - "55LF711U20: after a restart Amazon's home, promos included, shows for about 30 s before dumbtv home takes over by itself. The Fire OS 6 Keeper starts from the boot broadcast, which arrives late."
  - "55LF711U20: launcher.sh 1.2 stopped with 'dumbtv home is installed but not in front ()' although the home screen worked; the check read the front app once, too early. It now waits up to 10 s."
notes: "Three sets. 43C350NU (NS6711): full pass, dumbtv home took over HOME and the filter blocks updates; verify.sh exits 0. 55LF711U20 (Fire OS 6.7.0.8, NS6708): debloat (38 disabled), lockdown, the DNS filter and dumbtv home 1.2 with the Keeper; verify.sh exits 0, and the remote, HDMI inputs, Jellyfin, VLC, YouTube and the Appstore work. 50LF621U19: full pass with PRIME=1 ALEXA=1 LAUNCHER=1 DNSFILTER=0: 31 disabled, 0 protected, 5 absent, 0 suspect; verify.sh exits 0. Afterwards Echo control (TV off/on from standby, open app, volume), Spotify Connect, the voice remote, HDMI inputs and Prime Video all work."
