Filesystem Snapshot Analyzer
Fix bugs in an in-memory filesystem tree analyzer
Overview
You are given a filesystem snapshot analyzer that builds an in-memory tree of files and directories, then computes metrics like directory sizes, largest files, and junk file classification.
What's Broken
The fs_inspector.py file contains several bugs across its traversal, sizing, sorting, and classification logic:
- Directory ignoring only works at the top level, not at deeper nesting
- Directory sizes incorrectly include file entries in the result
- Largest files are sorted in the wrong order
- File classification uses case-sensitive extension matching
- Report builder doesn't pass ignore rules to directory size computation
