Description

The method signature plugin hooks run for normal method calls (obj.method(...)) but not for super().method(...), even though both resolve to a method and are then checked as calls.

Plugins that rewrite method signatures therefore cannot enforce the same behavior on super() call sites without a separate, hand-rolled checker.

Research direction

Start by tracing where get_method_signature_hook is invoked for normal obj.method(...) calls, then compare that path with super().method(...) calls. Confirm the fix by checking that plugins can enforce the same rewritten signature behavior at both call sites.
