The harness builds linear laws with blend.fillet_executive_p2's SmLinearFilletLaw constructor (FilletLaw::linear, PR #267); the SmBSplineFilletLaw(pCurve, crEdgeMap) constructor is not ported, so for B-spline laws it mirrors its zero-length-edge-map-means-[0,1] rule.

Still UNPORTED(blend.fillet_executive_p1) in intersect.surface_intersector_p1 (SmFilletLaw::Evaluate through the opaque law parameter of EvaluateLawPoint, and SmOffsetSurface::SetOffsetDistance through a shared surface): both wait for the executive's decision on how a fillet holds its offset surfaces.

GetFilletSolverOfEdge (edge uses through the adapter, then the edge-use lookup) is not compared on its own: the shim's handles are not real edges.

Not ported yet (UNPORTED(blend.fillet_executive_p1) sites remain): DoPiecewiseMerge, TestAndConvertBigRadFillet, SetFilletParameters, RemoveTopoEdges, CreateSmoothEdgeSequence, UpdateTopologyChanges, CreateFilletCorners, ~SmFilletExecutive and the SmApi*Fillet entry points. The GetFilletCornerOfVertex / NoteFilletError stubs in blend::fillet_solver::p2 and blend::fillet_geom::p3/p6 are not wired: they need FilletSolver's executive handle connected to FilletExecutive<O>, which is the same open design question as the surface_intersector_p1 stubs.

UPDATE (LoadFilletSolver): one explicitly passed FilletExecutive context retains native solver order and the unit back-pointer flag; ordered filleted vertices and one VertexEntry map of pending edgeuses or completed corners preserve the native load order and partial-error state. Actual solver offset surfaces, edge curves and existing-or-created curve caches supply the native reads. 89 native cases pass exactly on the standalone loader branch (61 retained plus 28 direct loader cases); the main refresh also passes all 260 native units without adding PR #596; remains partial, including CreateFilletCorners and other missing executive methods. Legacy opaque solver getter contexts remain explicitly unresolved; no duplicate getter ports. PR #819: RemoveTopoEdges (p1::remove_topo_edges on the target B-rep; ExecutiveAccess::remove_topo_edges is now required) and SetBevelCorner (FilletExecutive::set_bevel_corner through the owner's corner closure) ported and compared (fixture B-reps through the topology.brep_p10 snapshot; real SmFilletConvexNxNCorner objects in the executive script). Still unported, waiting for the retained fillet session's corner, solver and fillet B-rep stores (tdamsma's #767 stack): TestAndConvertBigRadFillet (rebuilds two neighbouring corners and deletes a solver), DoPiecewiseMerge with sm_FindMarkForContext1 (only enabled through SetDoPiecewiseMerge; boolean.merge_p3's piecewise_merge exists), the destructor and the SmApi*Fillet entry points. Fix (edgeuse::p3::trim_other_uv_curves): pass an edge-tolerance Kernel when trimming sibling UV trim curves so SmBSplineCurve::Trim uses pEdge->GetTolerance() (SmTol::GetZoneTol3d(this)) for degenerate-span removal; remove_topo_edges_mouse_two_struts now passes bit-for-bit (155/155 pass, 0 failed, 0 deferred, 0 known_mismatch).
