Review Summary

Here is my approval: the implementation in app/main.py correctly categorizes all variables into mutable and immutable types as required, and the output structure matches the task expectations. Functionality appears complete and accurate with no broken behavior or missing features. As a minor improvement, please fix the lint issues to unblock CI: remove the trailing whitespace at line 22 (W291) and add a newline at the end of the file (W292). After making those style tweaks, run flake8 app/ locally to confirm a clean pass. Nice work getting the core requirements right—just polish the formatting to meet the style checks.
