Excellent write-up! The shift of astrobiology from "discovery" to "data filtering" is an exciting change. With thousands of confirmed exoplanets, telescope time with instruments like JWST is arguably the highest value currency currently available in astronomy. Using STEHM to prevent us from wasting precious time on exoplanets that never had any chance of keeping an atmosphere could greatly improve the efficiency of discovery missions. Also of interest is the impact of the initial carbon inventory on understanding how the chemical starting ingredients of a planet shape its ultimate habitability - in fact, they may even dictate habitability more than size restrictions. I'm excited to see how they develop the simulation model to incorporate the effects of Earth-like plate tectonics!
