Erik 180b4a5010 capture(research): A6.P1 scen1 — retail.log with real hex-bits floats
v4 cdb probe captured paired field data for the Holtburg inn
doorway walk. 13,552 BP hits in ~2 sec of walking. Distribution:
  - BP1 transitional_insert: 7,686 (sub-step loop)
  - BP4 find_collisions:      5,818 (per cell per sub-step)
  - BP5 adjust_sphere_to_plane: 12 (the over-correction suspect)
  - BP6 check_walkable:        12
  - BP7 set_contact_plane:     18

Smoking-gun verification:
  BP6 threshold_h=0x3F2A0751 ≈ 0.664 = PhysicsGlobals.FloorZ
  BP5 plane normal = (0,0,1), movement = (0,-0,-0.75) — classic
       step-down probe against the ground polygon
  BP5 sphere radius = 0x3EF5C28F ≈ 0.480 m — player foot sphere

All hex-bits floats decode cleanly via Python struct.unpack('<f').
Decoder script TBD as part of the handoff.
