Notes

PARTIAL: difftest 427 cases (27 fixture: closed loops, open arcs, sub-domain, tangent plane, boundary iso solution, saddle singularity, tiny/huge scales, every FlushCurve branch, start point dedup and TestPoint removal + 400 generated over B-spline (incl. rational) and SmPlane surfaces), 398 pass bit-identical (max_rel_err 0), 29 deferred (surface.surface_p1 29: smsurf_GetSurfaceCache before DoTrace; the 23 surface.surface_p7 cases, SmSurface::EvaluateNormal in FlushCurve with a followed curve on B-spline surfaces, compare since PR #24 wired it, 22 pass and 1 moved to the cache); 5000-seed run clean, --perturb SENSITIVE; the shim's SectionTracer subclass (plane-section hooks, mirrored in the runner) drives the base class; DoTrace/FindBoundaryStartPoints/FindInteriorCurves take the surface cache as an argument until smsurf_GetSurfaceCache can hand one out; no UNPORTED(intersect.surface_tracer) stubs existed; 23 fns; largest: SmSurfaceTracer::TraceCurve, SmSurfaceTracer::FlushCurve, SmSurfaceTracer::FindInteriorCurves, SmSurfaceTracer::FindBoundaryStartPoints; cycle back-edges (call into later units; stub or co-port): intersect.surface_drop_curve(1), intersect.surface_drop_lib_p3(1), intersect.surface_silhouette(1); unit-SCC #22 (220 units); 317 upstream test entry points reach this unit [surface.surface_p6 wired (PR #92): 427 cases, 416 pass, 11 deferred (intersect.surface_drop_lib_p3 6, surface.surface_cache_p1 5)]
