The seat height, the horse's walk, gallop, acceleration and turn (VE_HORSE_*), its stamina (a gallop
over 6 m/s spends 6 a second, a walk gives back 3, 5 needed to gallop) and hay (0.02 a metre,
VEHICLE_HAY_MIN), the boat's stroke, turn and wind (VE_ROW, VE_ROW_TURN, VE_WIND) and where a rider
gets off (the horse's 1.2 m flank, the boat's 1.25 m wade) move into VehicleSpec (spec.ludic), held
per kind in VehiclesState.ve_specs and kept across a reset. vehicles_spec(kind, spec) sets one,
vehicle_spec(kind) asks it; a kind with no spec cannot be called. VEHICLE_HORSE and VEHICLE_BOAT stay
the kinds. The tests hand Maroon Lake's numbers in, and a new one holds a spec's walk and seat_h.

A called boat and one got out of drifted across the lake on the wind (the user's play of the bundle).
The tests hold a boat at its berth in a full wind for eight seconds, and one dropped out on the lake
where it was left.

A frame holding a new peak of facts made a record and grew the free list; now nothing is made until
64 are held at once. The two record-count tests hold the 64.

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.

Found with malloc_history over 1200 frames of play without the interface (the first Ludic function
on each allocating stack, live bytes at two marks): sh_loc built `name + "[0]"` per program per pass
per frame - 24.6 MB of 33 in the window; its callers pass both names as literals now. tick_set fills
the frame loop's one Tick instead of tick_new making one a frame. A ridden boat or horse said
VEHICLE_MOVED as a new fact every frame; the metres are added up in VehiclesState and taken once
(vehicle_moved_take / _kind / _x / _z). Play's growth without the interface: 92 -> 14.7 MB a minute
(maroon-lake tests/leakcheck.sh); what is left is phys_push (Physics' fix on lang/nav) and the HUD's
strings. Packages 407, ludic-dev test 305 pass.

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.

The vehicles are rows of a ludic.base Table with kind and owner as columns, every player's own by
an owner index and a nid map: vehicle_of walks only that player's rows, vehicle_by_nid is a map
lookup, and a player who leaves has their rows removed instead of the whole list rebuilt. ve_add
takes the owner, so the owner is filed once and never assigned around the table. Positions stay
on the record: a boat moves every frame and there are at most two a player. vehicles_test holds
the table (9 tests); the game builds against it and lab/unit passes (88 tests).

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.

ludic.base's Queue<T> carries a QueueTag (its name and pending count): queue_new(name), q_push(q, v),
q_drain(q), q_clear(q) take no BaseState, and core_undrained(tags) names the given queues still holding
facts. A reducer on a package's state can now call that package's verbs (wallet_earn(wallet_st, n)).
ludic migrate state --prune (ludicc --migrate-prune) takes out each state parameter a function no
longer uses, nor anything it calls, and the argument that fills it - including an argument for a
parameter the callee has dropped, which is taken out before the call is checked, so a generic's T is
told by the argument that says it. A reducer keeps its state. --dry-run now counts the edits it would
make. Every package was moved with it: 608 base_st parameters and their arguments, 1889 edits.
