What does File Engineering Tools do?

A collection of browser tools for checksum verification, MIME inspection, manifest drift detection, and upload test planning.

Does this run in the browser or on the server?

The utility logic runs in-browser for immediate analysis workflows.

How should results be used?

Use outputs as QA evidence, then convert repeated checks into CI validations and runbooks.
