FoxyzandClaude Opus 5.5 4c27d68e84 Research: avatar arm length vs real arm length (Porssut 2022, Ponton CHI 2024, fitted avatars 2023, VRChat/Bonelab/Nimso) -> decision: fitted physics body + calibrated arm length, avatars as skins; fix seated-arm wording

FoxyzandClaude Opus 5.5 35fbbf0306 Research: exhaustive Nimso Project TX study (82 video transcripts) + Boneworks/BIMOS rig reference 
- research/nimso-project-tx.md: chronological per-video notes 2017-2026, topic synthesis,
  VR Messs scope, proportions & calibration (Winter/Drillis-Contini/Dempster tables verified),
  open unknowns
- research/sources/nimso-transcripts/: yt-dlp auto-caption transcripts + dated index (re-pullable)
- research/vr-physics-rig-hexabody.md: BIMOS/HexaBody/Boneworks reference, Box3D native joint
  mapping (spherical/motor/prismatic/distance), superseded-as-target note
- AGENTS/HANDOFF research pointers

FoxyzandClaude Opus 5.5 cb518999e5 Body Stage 1 collapse root-caused + fixed: NaN in torso servo math (GetAngle = 2*acos(W) at W=1.0000001), not solver stacking 
- BodyMath.RotationError: atan2-based shortest-arc error (no NaN, no GetAxis gain collapse
  inside 0.16 deg); used by PhysicsTorso orientation servo and PhysicsHands rotation lock
- BodyMath.ResetIfNonFinite escape hatch on torso + hands
- PhysicsHands.Drive extracted (static) so spikes run the real hand chase
- CollapseSpike: deterministic repro (slow yaw drift across a parked chest, 7/40 NaN on old
  code) + solver-stacking scenarios (seated chest in table, two-hand-welded 50 kg anvil,
  real PropShop) — 49/49 clean after fix, x3; all other spikes PASS x3
- Failure brief RESOLUTION section; HANDOFF/AGENTS updated
