State of the work
PR002, PR003, PR004 and Altea suggest a visible family of red/orange/plasma orbs with non-ballistic motion, silence, hover, tandem/rotation or low altitude.
The official IR/SWIR layer suggests a related sensor/non-visible mode: compact/circular objects over water/land with variable speed and contrast loss.
Historical continuity supplies analog language, not origin proof. The most parsimonious current model inside this research frame is a dark core plus field/plasma envelope exciting the atmosphere. The correct path is spectroscopy, EM sensing, triangulation and a DWARF 3 station network.
Operational thesis: if this is a real physical family, we are not seeing a simple fireball. We are seeing a luminous atmospheric interface around something else.
