Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Supply Chain / Integrity: Downloaded/cached tokenizer files were used without integrity verification, allowing tampered files to be loaded and potentially cause incorrect tokenization or code execution.

Supply Chain: Floating GitHub Actions references to mutable tags (e.g., @v6, @v3.1.4) allow an attacker who compromises the action repository to inject malicious code into the build pipeline.
