Tri-pair merge (TRI_QUAD_MESHING_PLAN §3.1, phase G2). "Blossom-quad"-style greedy pairing: score every mergeable interior edge by the quality of the quad it would produce, then accept pairs best-first while neither triangle has been taken. The perfect-matching refinement is out of scope.
QUAD_MESHING_REDESIGN_PLAN_2026-09-06.md §4.6 / P1: the quality gate and ranking are mesh::quadAcceptable / mesh::quadScore (scaled Jacobian, aspect, skew) with 60°/120° defaults. The previous score minAng/maxAng × minSide/maxSide rated the 60°/120° rhombus two equilateral Delaunay triangles form (0.5 × 1.0) the same as a perfect 2:1 rectangle (1.0 × 0.5), so it could not tell the diamond from the good quad.
