The per-frame sweep over physics, character, vehicles and nav found three fact makers that made a record per fact: contacts and splashes, the character's and the vehicles'. Each keeps a pool now, as wildlife's and npc's do (q_unheld). phys_sink, asked on every removal, built two new lists each time; it filters into a kept spare pair and swaps. ludic.nav's paths and crowds already allocate nothing, and none of the four builds a string per call. What remains at load, reset or a world swap is not per frame. vehicle_feed takes its state mut. vehicles_test: 1000 fed facts, drained turn by turn, use at most 4 records. All packages 421.

phys_pose, phys_ray, phys_push and phys_walker_pose each made a new record per call, some several times a frame, and Ludic never gives one back. They now fill the caller's PhysPose / PhysHit / PhysPush / PhysWalk and return whether they found anything. phys_overlap returns a count; phys_overlap_id(i) reads each id back. The package's own uses (phys_resolve, phys_row, phys_walker_move) read the values buffer directly. Tests take small allocating helpers. physics 20, character 15, vehicles 8.

tools/native/lib.sh passes -implib rather than /implib: Git Bash rewrites an argument starting
with / into a Windows path, and lld-link was handed 'C:\Program Files\Git\implib;...'. Both DLLs
import KERNEL32 alone, so no C++ runtime ships beside them.

The water floats the hull, the wind pushes every boat as a force, the lake bed stops it at the shore;
the swell takes the outward share of a stroke. ludic.physics: phys_hull_add (a buoyant box),
phys_row, phys_bow_speed, and a test that floats one a quarter under, rows, turns and grounds it.
The vehicles tests row a real Jolt hull on the fake shore; the horse moved to horse.ludic.

The package keeps the rules and hands them over each step: speed and heading, whether a jump
leaves, CHAR_STEP and the boots' slope limit. The walker (Jolt CharacterVirtual) does gravity,
landing, steps, slopes and following the ground down. Too steep is ground too steep facing the way
the body wanted to go; stepping off an edge is not. ludic.physics: phys_walker_move (follow the body
if something else moved it, then step), the slope limit, the jump always honoured. The character's
tests run on a real Jolt walker over the same fake world: 15 pass, a knee-high boulder now a step.

Five new tests: stand and walk at the asked speed, a low stone is a step and a tall one a wall, a
jump up and back, a crate shoved aside, a hull turned by a torque and carried by a force.

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.
