Limit Method Parameter Count

Overview

Method signature cleanliness (excessive parameter count).

ATC Finding Message: Method signature has too many parameters; consider grouping into structures

Rationale

A long parameter list is hard to call correctly because positional order and optional parameters are easy to mix up. It usually means the method has too many responsibilities and must change whenever a new input is needed. Group related inputs into a structure or parameter object so the signature stays small and self-documenting.
