Answer earthquake, CCTV pick and tracked sprite reads from Core

Earthquake analyst records come from the events the layer drew, gated on
its own enabled flag, instead of reading each entity's position and
property bag back; the discs no longer carry the bag. CCTV coverage rays
and projection planes record their camera id in a layer pick store
instead of a cctvCameraId entity property, with the same ownership checks.

The tracked flight, military and local ADS-B billboards record their size
and distance scaling as the entity record's sprite, which the close-range
camera guard and the screen annotations' tracked footprint now read in
place of the billboard's property getters.
