Our own shim (native/shim/jph_shim.cpp) over Jolt built from the pinned tag with cross-platform determinism and no fp contraction: shapes as handles (box, sphere, capsule, cylinder, dome, offset, heightfield, mesh), still/kinematic/dynamic bodies by id with real removal, rays, top_at and push (what CharacterGround asks), overlaps, buoyancy against the PhysWater port, contacts recorded in C and drained as PHYS_HIT / PHYS_SPLASH facts. Fixed 1/60 steps, at most four a frame. Nine tests against the real library, including a pile run twice to the bit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# builds lib/<target>/ for ludic.physics: Jolt Physics at a pinned tag, and the shim over it.

# Cross-platform determinism is on (the Mac and the PC must agree in co-op), and floating point
|
|
# contraction off, which it needs. Objects go to build/native; about a minute on eight cores.
