+
+Three new boolean logic nodes have been added to complement the existing `ConstBool` node:
+
+- **`NotBool`** (`! Not`): Logical NOT — inverts a boolean input
+- **`AndBool`** (`&& And`): Logical AND — true only when both inputs are true
+- **`OrBool`** (`|| Or`): Logical OR — true when either input is true
+
+These enable combining boolean conditions within the graph — e.g. `is_grounded AND is_moving` to drive blend parameters or FSM transitions.
