# Contains an AI-generated summary for a given set of events. You create these summaries with a time window
|
|
# and a set of collections. We only store a key derived from the accessible events for those collections,
|
|
# so that we reuse the same summary for users with different time zones or different accesses as long as the activity
|
|
# is the same. This is important to keep AI costs down.
