jyvikoandClaude Opus 5.5	0ec1882697	solver: tie weights and constraint reduction independent of the structural mesh (#358) ... The tie's mortar rows take any node numbering and degree-of-freedom kinds, and Reduction takes a DofLayout, so heat transfer can reuse both.

jyvikoandClaude Opus 5.5	f9981d305e	solver: ties by dual mortar constraints ... Each secondary node follows the main surface under it as the weighted average u_A = sum_J (M_AJ / sum_K M_AK) u_J with M_AJ = int psi_A N_J over the reference overlaps and psi the secondary faces' dual shape functions (Wohlmuth 2000), so the secondary mortar matrix is diagonal; the rows join the couplings' constraint elimination in every implicit analysis. Uncovered secondary nodes stay free with a warning; heat transfer and explicit dynamics refuse ties by name. Tested by the tie patch test on non-matching hex8/tet4 meshes.
