Checksum Verification
Use checksums to confirm file integrity after download.
shasum -a 256 your_file_name_here
# Compare output with SHA256 values listed above.
Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.

Validation Methodology
- Verify listing and extraction behavior across tools.
- Check compression ratio assumptions and extraction limits.
- Test zip-slip/path traversal protections in upload pipelines.
