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

// difftest shim for unit `topology.shell`: SmShell::IsInnerShellOf (source/SMLib/src/
|
|
// SmShell.cpp) on every pair of shells of a B-rep with internal voids.
|
|
//
|
|
// One entry point, sc_topology_shell_inner_shell_of(in, n_in, out, cap, out_len). The input
|
|
// is `n_steps (op kind x y z a b c)*n_steps`: step 0 makes the body (`op` ignored), each
|
|
// later step builds a primitive and combines it into the body with
|
|
// SmApiBoolean(body, primitive, op) (`op` an SmBooleanOperationType). `kind` 1 is
|
|
// SmApiCreateBox(origin (x, y, z), a, b, c), 2 SmApiCreateSphere(center (x, y, z), a).
|
|
// A failing constructor or Boolean is SC_ERR_ARG (validated inputs avoid them).
|
|
// Output: `n_regions (n_shells)*n_regions` (SmBrep::GetRegions order, each region's shell
|
|
// list order), then for every shell i in that order `IsInnerShellOf(NULL)` followed by
|
|
// `IsInnerShellOf(shell j)` for every other shell j in order (the SmBoolean, 2 = UNSURE).
