- legs brake landings at 4.5 g; vertical support is a rate-limited servo
(no launch when stepping onto a mantled ledge)
- ground control pushes back on movable ground (seesaw tips under the player)
- playground hinges use absolute paths (joint paths resolve from the joint)
- big props grabbable via surface query; Reset props keeps playground pieces
- spike: landing, seesaw, playground joints/grab, person-like wall climb

- view follows the body (deadzone, smoothed, hard 8 cm limit); no drift over
six held poses; hanging keeps the view on the character's head
- hold-back measured at the hips, capped leg push while held, stiffer balance
- sticky legs tuck with free-space check (fixes the mantle shove loop)
- strength asymmetric by direction; structural guide strength push-only
- limb/torso friction set before AddChild (Box3D reads it only at creation)
- new phases: pose hold, hang, human-motion mantle, hand-over-hand wall climb

Spike now runs real input (90 Hz sample-and-hold tracking + jitter under 144 Hz
physics), which reproduced the playtest. Root causes fixed:
- PoseFilter/RagdollDriver: timestamped extrapolation of tracking, one tick
pipeline shared by PlayerRig and the spike
- low-pass all feed-forwards (ground control amplified jitter by body mass)
- arm muscles back to local targets (physical-frame aim fed chest rotation back)
- structural hand strength only when braced or holding
- no free-path view chasing while grounded (8 m crouch slide); stick hold-back
- explicit inertia for the Legs body (shape-less tuck tumbled the pelvis)
- world grab: Box3D shape queries return a null collider, use collider_id
- new crouch-hold phases; world-grab detection asserted
