Contributor guide
Research direction
Start by locating the injected analyzer rule and the Catalyst-related loop in the Scala codebase. Trace why the loop repeats and identify existing tests covering analyzer behavior; done means removing unnecessary iteration without changing rule results, with validation from the relevant test suite.
