Behavior

Behavior Modes

Mode	Trigger	Processing Path	Response Shape
Global mode	Authenticated user is global admin	Aggregates selected/all-app documents for period and builds full punch-card matrix.	Raw object { data, dayCount, labels }
Restricted mode	Authenticated non-global user	Restricts filter to user-app access list before punch-card aggregation.	Raw object { data, dayCount, labels }

Impact on Other Data

• This endpoint is read-only and does not mutate persisted metrics.

Limitations

• Non-global users can only see data from accessible apps.
• avg field in slot payload is present but not computed in this implementation path.
