TvTextInputAutoOpenBehavior.onFocus/.onFirstFocus were handled by both TV-keyboard state machines but selected by no caller; FocusableWrapper.longPressDuration duplicated the controller's own 500ms default; FocusableActionBar.mainAxisSize was never passed; FocusableActionBuildState carried focusNode/isFocused/isKeyboardMode that no builder reads (AGENTS.md updated to document the surviving showFocus/animationDuration pair). includeFocusSemantics stays — focusable_media_card passes it.
