What it includes

A readiness checklist for teams that already rely on FingerprintJS visitor identifiers.
A contract-test example that validates the fields an application expects from browser-identification results.
Server rollout notes for version-aware identifiers, dual-write windows, and cleanup criteria.
Upstream etiquette notes for proposing improvements to the official FingerprintJS project.

Positioning

FingerprintJS is maintained by Fingerprint. This Mirogate lab is unofficial and is not a replacement for the official package or docs. Its purpose is to help application teams prepare their own code for major-version change without a blind cutover.
