AP / SOLAR SYSTEM / 08
Ocean worlds
A comparative atlas of planetary environments, liquid-water evidence, energy sources, chemistry, stability, and mission access across the Solar System.
Habitability describes environmental potential. It is not evidence that life exists.

MODEL / 1.0
Comparative evidence matrix
A transparent research-priority index, not a probability of life. It combines solvent evidence, usable energy, chemistry, environmental stability, evidence maturity, and sampling access.
