      What this check looks for
    Description, as the server wrote it
    Check that a class at a gym can be reserved online right now and get the link where the visitor signs the gym's waiver and pays (or reserves free). Returns the class's next date and start time, price, cancellation policy, and reserveUrl. It does not book anything: the visitor must open reserveUrl and sign and pay themselves. When status is unavailable, reason says why and reservableClasses lists classes that can be reserved instead.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
