 After extensive brainstorming, the following decisions are locked:
 
-| Decision | Choice | Rationale |
-|---|---|---|
-| Geometry generation | External Python (Constrained Delaunay) | Full access to scipy/triangle/gmsh, debuggable, fast |
-| FEA strategy | Reserved-region monolithic remesh | Keep load/BC topology stable while allowing local rib updates |
-| FEA solver | NX Simcenter + Nastran (2D shell) | Existing expertise, handles complex BCs, extensible to modal/buckling |
-| NX role | Extract sandbox faces, reimport profile, remesh + solve | Reserved regions preserve associations; no assembly merge pipeline needed |
-| Optimization | Atomizer (Optuna TPE), pure parametric v1 | One FEA per trial, ~2 min/iteration, stress feedback deferred to v2 |
-| Geometry transfer | JSON-only round trip | Deterministic, scriptable, no DXF/STEP conversion drift |
-| Plate type | Flat, 200–600 mm scale, 6–15 mm thick, 16–30 holes | Shell elements appropriate, fast solves |
