Detailed Description

One solve phase's body copies (docs/contact_solve_framework.md §4.4, §4.5, §WO-4 item 2): the hub copies of the colouring (extra slots [slotBase, slotBase + nCopies) appended to the SoA, per-edge slot overrides) and the fold GROUPS – one per body updated through more than one slot in the phase (a hub's base + copies; in demStep's position phase also the periodic images of a body).

Group g's members are groupSlot[groupStart(g), groupStart(g + 1)), base (the body's own slot) first; groupShift is each member's periodic shift (0 but for images and their copies), groupK the active-copy count k, seedX / seedW the phase seed sigma of the base. Grow-only views; nGroups == 0 = the phase has no copies (every sweep runs on today's indices and masses).
