Erik 92cd7238ff docs(phys L.2d): design spec for slice 1 BSP-hit diagnostic + L.2d reframe ... Reframes L.2d direction based on ACE BuildingObj.cs:39-52 + named-retail acclient_2013_pseudo_c.txt:701260: retail's find_building_collisions is one BSP test on PartArray.Parts[0]. No per-cell walkability. Per-cell work (find_cell_list, point_in_cell, sphere/box_intersects_cell) is L.2e territory. Slice 1 is now a read-only BSP-hit diagnostic that captures full collision evidence per L.2a [resolve] hit=yes line. Distinguishes 3 hypotheses (wrong BSP loaded / over-registered parts / BSPQuery flaw) before any behavior change. Slice 2 is the actual fix, scoped from slice 1's evidence. Authors: brainstorm session 2026-05-13 (cold-start from L.2a slice 1+2+3 evidence). Predecessor handoff at docs/research/2026-05-12-l2a-shipped-l2d-handoff.md.
