The user's play of the bundle: the character shook while seated. chr_sit_tick eased the body onto the
seat point at the ground's height, then the same frame's chr_travel handed it to the walker, which
pushed it off a log, a bench or a boulder beside the seat; the next frame pulled it back. Unwalked, the
game's walker parks as it does under a rider. A hold's turn toward the work fought the seat's yaw the
same way. The new test sits the body against the boulder: 4.63 m from a seat at 5.7 before, still after.

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 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.

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.
