Summary

  • Track 0064-HandPalmDigitRefine: thicker palm pad (th 0.36, pad 0.78) so pad depth clears the 0062 wrist soft bead
  • Phalanx length taper (0.24, 0.18, 0.13) sum 0.55 + distal radius 1.05× (anti-stick tips)
  • Keeps 0048 fr 0.16 / splay 1.95 / groove and mitten 0.72 fences; schema 1.4.0; MCP 46

Product evidence (nofuse_0064, gitignored)

  • palm ry 0.0340 / wrist 0.0319 (ratio 1.066, was 0.74)
  • middle L 0.0290 > 0.0218 > 0.0157; distal L/r 1.248 (was ~2.0)
  • constraints_ok; C_palm_ellipsoid pass; n_parts 116

Test plan

  • uv run ruff check . + format --check + basedpyright + pytest (pre-push)
  • extremity suite T0/T5/T5b/T15–T17 (B16 dual)/T19 + fences
  • CI green before squash-merge

Raise palm thickness/pad so pad depth clears the 0062 wrist soft bead,
and replace equal finger segments with PP>MP>DP length taper plus mild
distal radius scale. Keeps 0048 fr/splay/groove and mitten fences.
