"State" key in Timesheet object not in API Documentation

[wreevesc]

The key "state" in the JSON response (see below) for /timesheets?start_date=2024-08-29 is not in the API documentation. Is this equivalent to looking in the supplemental user data for "approved_to"? I'm only seeing "APPROVED" and "CLOSED" state values. Are there other states? What are their meanings?
