Recommended QA Flow

Start with representative formats and smallest sizes to validate core handling.
Expand to larger files to benchmark memory, timeout, and streaming behavior.
Verify file integrity using SHA256 checksums on each format page.
Use manifest JSON endpoints to automate regression test fixtures.

Data Quality Controls

Consistent naming by format and target size or duration.
Manifest metadata exposed for machine-readable validation.
File pages include MIME type and checksum integrity signals.
Static hosting paths remain stable for test automation use.
