Violet White fix: corner pyramid fills chamfer bevel gap completely 3mo ago

test-case.modeler

fix: corner pyramid fills chamfer bevel gap completely Root cause: Manifold boolean cube - column produces mesh where interior rim edges have no EdgeRecord. find_edge_by_rank matched exterior edges (same normals, different position). Previous fix (tetrahedron) left a lip on top/bottom face because the bevel-intersection point was not covered. Corner pyramid (5 vertices, 6 triangles) adds V4 at the intersection of both bevel planes, fully filling the gap. Fix: 1. find_edge_from_selection: reconstruct EdgeRecord from selection data when registry edge line-distance > 0.01. 2. find_edge_by_rank: .abs() normal matching, line-distance closest-hit. 3. Corner pyramid instead of tetrahedron — 5 vertices (adds V4 = (n_b_a+n_b_b)*d), 6 triangles, covers the full corner. 4. Normal detection: edges may have face_normal_a/b in any order; detect top/bottom face normal (Y=±1) for pyramid construction. 5. Wedge eps = 0, all overlap handled by corner pyramids. Tests: all 269 Rust + 118 Python + 22 shell pass.
