Advanced rock-mechanics preview
Four research-grade physics modules distilled from Cong (2024), Hou (2019), Nikam (2016), and Yadav (2011). Each card is a live, pure-math preview of a library that ships with drift-guard tests and is wired into the relevant builder/designer surface. Sweep results are deterministic from the saved inputs — restoring a scenario reproduces every matrix below it.
