Motivation
extend ModuleNamemakes module instance methods available as class methods, but Method-Ray currently reports false positives (e.g.,User.find→ "undefined method") because Singleton type resolution has no fallback for extended modules. This is a common Ruby pattern used widely in Rails and other frameworks.Changes
