PhysicsNeMo Discoverability Help a user navigate PhysicsNeMo: point them at files, folders, examples, and docs in the repo at its current state . Never write training code; never cite a path from memory. Core principle PhysicsNeMo evolves — classes get renamed, examples move, graduates. Any static list of class names and paths rots, so discover, don't remember : enumerate from the live repo every turn. PhysicsNeMo is composable : each solution is a product (model family × datapipe × training strategy × config). An example is one reference instantiation of that product, not a prescription. Sur…
