It does not make sense to trigger a failure for the method scopes, but it happens:

-------------------------------------------------------------------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE

PSR 2 shows examples of this within the code blocks provided (not explicitly), where the abstract method declarations occur before any of the concrete method declarations.

PSR 12 does not state against this.

The scoping rules should still apply, but abstract methods are defined on top of concrete methods, following the scope rules, then concrete methods, following the scope rules. At least, that's the expectation.
