fingerprint-ci-gate

Catch browser fingerprint regressions before they ship.

CI testing

What it does

Gates CI builds on browser fingerprint regressions using saved scans, baseline diffs, or a minimum score.

When to use it

Use when adding fingerprint or headless-detection checks to CI pipelines or tracking fingerprint scores across commits.

Give it a project; it adds a version-pinned fingerprint scan and CI gate with baseline comparison and scan artifacts.
