Two cfg(android) issues hidden from Linux CI: - android_clipboard.rs: JValue was imported but never used (JValueOwned covers all call sites). Removed to satisfy -D unused-imports. - stats_plugin.rs: both arms of the clipboard match now return () via explicit block+semicolon, resolving the type mismatch that pinged-pong between runs due to bidirectional match-arm type inference.
