Refreshed once a day
One bar per day, split by what changed: outside organizations added to or dropped from a sharing list, a portal’s own camera count moving, cameras added to or taken off the volunteer DeFlock map inside these departments’ areas, a portal that stopped publishing a figure, a read that failed. The portal count is the department’s official figure; a map edit is dated by the edit, not by when the camera went up. Pick a day to see its full state and every change by name. The arrow keys step through days, and the address bar carries the day and filters, so a view can be linked.
