SOLID - Liskov Substitution
Subclasses must honor the contract of their parent class. Don't override methods to throw "not implemented" exceptions. If a subclass can't fulfill the parent's behavior, the inheritance hierarchy is wrong—consider composition instead. Preconditions can't be strengthened; postconditions can't be weakened. Violating LSP leads to fragile code with instanceof checks.
