Different fermion species follow specific anti-commutation rules

The claim that fermion species follow anti-commutation rules is a well-established foundational principle of quantum mechanics (the spin-statistics theorem). Paper [7] directly addresses the spin-statistics theorem linking half-integral spin particles to anti-commutation relations, while Paper [3] discusses how specific interactions modify canonical anti-commutation relations for specific fermion variables. Because this is a standard textbook property of quantum mechanics, it qualifies as common knowledge, but the retrieved literature confirms the underpinning physics without any papers refuting the rule.
