Unclear The finding does not say which feature or code path now uses this helper.

What

Claude Code has a new internal helper that checks whether a file contains a given byte pattern by reading it in bounded chunks, rather than loading the entire file into memory at once.

Why

This makes checking whether a file contains something more memory-efficient, especially for large files.
