C++ shims, FFI bindings and runner cases comparing the WP2 ports of #1419 against the reference: AssertNoPeriodicJump (240 cases), sm_AssertTestFace37 (424), SmVertex::CheckPointers (65), SmLoopuse::IsLoopuseSideInSurface (159), SmEdgeuse::HasDogLegNearPole/IsEdgeuseSideInSurface (212) and SmShell::IsInnerShellOf on box/sphere bodies with voids and islands (33). All pass bit-identically with no deferrals. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SdcgEtgaA54W2nr8dK1EYp

|

// dereferences), or `-1 status` when the B-rep cannot be built.
