Whether this module definition's membership can change through the passage of time alone. True means the criteria are anchored to a moving reference point ("no visit in the last six months"), so membership goes stale without any write and a periodic re-evaluation is required. False means membership can only change when data changes, so a change feed is sufficient. Derived from the criteria logic, not declared beside it.
