Module determinism 

Falling-ragdoll determinism scene helpers from shared/determinism.c.

Builds a grid of ragdolls over mesh grounds and hashes settled transforms. The final EXPECTED_HASH gate in test_determinism.c stays deferred until task-6 lands mesh narrow-phase (bodies currently fall through meshes).

The content hash itself (b3Hash / crate::core::hash) already lives in crate::core; this module adds the world-transform byte layout used by the scene.

Functions

create_falling_ragdolls

Build mesh grounds and spawn the ragdoll grid. (CreateFallingRagdolls)

destroy_falling_ragdolls

Release owned mesh data. (DestroyFallingRagdolls)

hash_world_transform

Hash a world transform’s raw little-endian field bytes in C declaration order, matching b3Hash(hash, (uint8_t*)&xf, sizeof(b3WorldTransform)) on little-endian hosts. (determinism.c UpdateFallingRagdolls)

update_falling_ragdolls
