Erik bb1e919ef2 docs(physics): spec + plan + findings for ISSUES #83 walk-miss probe spike
Three docs from the indoor walk-miss probe spike landed in commits
27c7284..a2e7a87:

- Spec: design of the [walk-miss] + [floor-polys] diagnostic emissions
  with the H1/H2/H3 disambiguation matrix.
- Plan: 3-task TDD implementation plan (flag, aggregator, emissions).
- Findings: live-capture analysis showing H3 (walkable_hits_sphere /
  adjust_sphere_to_plane synthesis rejection) is the dominant defect.
  817 of 876 ground-contact misses (93%) cluster at dz~0.48 m, while
  the 7 HITs all sit at dz~0.46 m — a 2 cm boundary between working
  and broken that points at the sphere-overlap math, not the probe
  distance. H1 (multi-cell iteration missing) is real but only 3%
  of misses, secondary. H2 (probe distance) ruled out.

Next step: line-by-line decomp comparison of FindWalkableInternal /
walkable_hits_sphere / adjust_sphere_to_plane against retail at
acclient_2013_pseudo_c.txt:322032 / :323006 / :326793, then design
the fix in a follow-up session.
