+**Status: 1.0.1.** The version tracks the upstream release it is ported from and
+tested against, usd-brep v1.0.1. All of SMLib is ported:
+- primitives, booleans, fillets and chamfers, offsets and shells, sweeps, healing, and
+  mass properties;
+- a unit is green only after differential testing against the C++ original confirms
+  identical topology and values within 1e-9 relative, with any per-key absolute floors
+  documented in its report.

+The public API mirrors SMLib's and may still change between minor versions while
+integrations settle.
