# List the measurement IDs the current user is watching

> Return the IDs of measurements the current user is watching.

A flat list of IDs for membership testing on the client. Includes watches on
measurements that may since have finished; the Lab wall intersects them with
its live channels, so finished watches simply do not surface.

        Returned as a flat list of IDs (not full rows) because callers only need
        to

        test membership — e.g. to mark channels as watched on the Lab wall.
