Detailed Description

Per-edge slot overrides of a phase's hub copies (docs/contact_solve_framework.md §4.4 item 5) plus the per-slot mass-split flag and relaxation of §4.5.

Empty views = today's indices, no relaxation (the identity). a(e) / b(e) are the slots of edge e's A / B end (-1 = the default index: realIdx(bodyX) in the velocity phase, the raw contact body in the position phase). Every STATE access of a phase's sweeps goes through slotA / slotB; keys, labels and side flags keep the body.
