Checked on both machines with a bundled Jolt probe: the licence and the library in place, the app
signed (Mac) and the probe's ball landing at the same height on both.

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.

Conflicts with 0.R5's state defaults in ludic.wildlife resolved; wl_step writes the push's answer, so
its callers take WildlifeState mut again.

- ludic.wildlife: WildlifeWorld.push / pushed_x / pushed_z (defaults change nothing); a ground
walker's step is slid clear of a still thing with a body from its species' size and scale, and
a step that gets nowhere turns away as the water does. Birds are not pushed; no dice added.
- ludic.npc: NpcWorld.push / pushed_x / pushed_z (a person 0.35 m round) in npc_walk, and
NpcWorld.clear (default true), which npc_line_ok asks at 1 m so a detour does not cut a trunk.
- ludic.aim: AimView.clear replaces AimView.ground and the ground march; the pick asks the line
a body's width short of where the ray enters the thing (aim_clear_at(t, back)), so a solid
thing does not hide itself. probe.ludic (the ground-agreement probe) and AimView.dry are gone.
- ludic.photo: PhotoLens.clear replaces PhotoLens.ground, PhotoLens.trunk and the march.

- a CAMetalLayer on the view (cocoa.ll win_metal_layer), VK_EXT_metal_surface, QuartzCore linked
with Vk.*; the drawable measured after the layer sets the backing scale
- vk_mac.ll opens MoltenVK directly after any loader: a bundle ships only libMoltenVK.dylib
- a covered window is not presented to (win_visible); one frame in flight on macOS
(R3D_VK_INFLIGHT), with images, buffers and descriptor pools held until it is done
- win_held / win_mouse / win_pad / win_touch / win_text / win_present pass slice elements (arg_buf):
every windowed program died on its first input poll
- variants.list and SPIR-V for the three NEAR_FADE foliage programs

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.

Maroon Lake: 149 parameters became read-only. What stays mut is a real write - in the packages mostly a
lazy start inside a question (things_all, gear__ensure), which is what to take out next.

collide.ludic (circles in a cell grid that could not be removed) and its Render3dState fields are
deleted, and the reload example stops asserting colliders. A game still calling col_* must move to
ludic.physics first (Maroon Lake's src/solid).

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.

native "<target>" "<path>" in a package's package.ludic; the compiler records the libraries of
every package a program imports and writes them into the IR (; ludic-native:), so ludicc -o,
ludic build, ludic test and ludic bundle all link one list. macOS: an rpath to the package and to
Contents/Frameworks, where ludic bundle copies and signs each library and drops the build
machine's rpath. Windows: the import library, the .dll copied beside the exe (--natives-out for
the bundle). tools/native/lib.sh builds from a pinned, checksummed source with clang on both
machines; ludic.nativeecho is the worked example; the shim rules are in packages/README.md.
Linked at build time rather than dlopen (docs/PACKAGES.md says why). Reseeded.

The old kit read Input.mouse_x() * gl_scale; ludic.ui read it raw against a layout sized in
drawable pixels. A backend says how many screen pixels one pointer unit is (pointer_scale);
render3d's is gl_pixel_scale(), 1 on Windows and headless.

A reach through Port.member() follows that member's binding (or its default), and Registry[i].field -
or a local holding Registry[i] - follows that field in each entry, so a question asked of a port or a
table that also holds verbs no longer reaches the verbs. In Maroon Lake that took the valley's
'what is this Thing called' from 47 states it could change to 1. examples/state/write_reach.ludic.

What only becomes known inside the drain - a value another reducer just set, the map in play - no longer
has to be faked into the action, so a verb that reads several systems while it changes one is a reducer
instead of an act handed its states. A second state to write is still refused, and the message says the
way out. examples/actions/reads.ludic; reseeded.

ludic.ui runs a frame's presses after drawing it, and what they dispatched waited for the end of the
phase - after the host had presented - so a button's change showed a frame late. Decided: drain, not a
phase per action. ui_show and ui_press drain the queue once the presses have run, so the code after
them and the frame presented next see the change; a host that runs presses some other way calls
drain_actions() before it presents.

A game's exported UiAct collided with ludic.ui's, which nothing outside ludic.ui uses: it is private
to ludic.ui now, and a private record of one spelling in two modules never clashed. A real clash - a
type named like one a package exports - is still refused, and the message names the package and the
way out (`ludic_ui exports it, and exported names are one namespace - rename this one, or declare it
without export inside a module of your own`).

A step list or a registry of fn values takes no state and still reaches every state its steps take.
The compiler now writes `reach <n> <function>` - every state a function can come to by a call, a
`fn f` it writes or a global holding fn values it reads, to a fixed point - and ludic deps reports
widest_reach beside widest_function, with how many of those states the function does not take
(Maroon Lake: app_boot, 72, all 72 through fn values). --widest N lists the N functions that take the
most states with what each reaches; --reach N orders them by reach. A baseline without widest_reach
does not hold it until rewritten.

`function kind_of(f: CharFact)` for a CharacterFact was taken on trust and failed in the code writer
as "member access on non-aggregate". A capitalised type - plain, in a slice, or a generic's argument -
must name a declared property, record, state, event, enum, action or packed value type, or a type
parameter of its declaration: `kind_of's parameter f: there is no type CharFact`.

On Maroon Lake the prune gave home_keep_records(base_app_st, home_st, r: RunRecords, save_app_st) a
second save_app_st at the front, and every call a second argument: a state declared after a plain
parameter was not counted as declared. It is now, and a call to such a function is never given the
state again. `ludic build --check` let the duplicate through and clang refused it; the checker now
refuses a function that names two parameters alike (`add names two parameters n`).

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.

- the function that calls every reducer (and the action queue) is written in the program's own
file: in the first action's file it belonged to that module, depended on every module with a
reducer, and joined a game's modules into one 69-module cycle (examples/actions/modules and a
ludic deps case hold it); the state instances, the queue and the reducers make no deps edges
- ludicc --check / ludic build --check lower the program too and write nothing, so the code
writer's refusals are in it: a bind to a function that is gone, an unknown name (and the checker
now refuses fn <missing> itself); rejects bind_missing_fn, unknown_name, registry_count_key
- def R count is refused: its constant would be PREFIX_COUNT, the registry's size
- a file's module, package, trust and numbers-float are tables, and from the check on the lookups
of functions, enums, records, globals and externs are too (tagged enums kept as a list): Maroon
Lake's check-only build went from about 20 s to 7 s including lowering, its IR from about 2
minutes to under 10 s; duplicate declarations are found by table, not a pair of loops
- threads.ludic's pool check gives each call a little work, so a busy machine cannot run them all
on the caller before a worker wakes (it failed one run in three under load)

It lowered to an i32 compare of two pointers, which the IR refused. Two strings with the same text
are equal now, a null only to a null, and a failure says expect_eq failed (got "camp", want
"lake"). examples/library/testing_strings.ludic (two tests fail on purpose, and the output is
checked); ludic.base's actions_test uses it again.

widest_function: the most states any function or entry point of the program's own takes, with
which one; --check holds it like the other numbers and --baseline writes it.

action Name { fields } is a typed record; reducer State on Action(s: mut State, a: Action) { ... }
in the module that owns the state takes exactly that state and the action (a second state is
refused); dispatch Action { fields } queues one from anywhere, the queue supplied by the runtime.
The queue is drained at the end of every phase of the frame loop, after every phase of ludic.base's
core_tick_all, and by drain_actions(): in dispatch order, each action's reducers in the order of
their states' names, an action a reducer dispatches queued behind, a queue still growing after 64
rounds stopped with the action named. Examples actions/pack, phases, runaway; rejects for a second
state, a reducer on a non-action and an unknown dispatch; ludic.base's actions_test; LANGUAGE.md.

- component Name (a: mut A, b: B) { ... }: every getter, default, function and event takes the
header's states before the instance; a member's call to another passes them on; the glue is
supplied them; the template never sees them; a read-only one is read-only in every member
- ludic migrate state: a component's members' needs go into its header (added to an existing one,
mut added where now changed); a field read or a member call inside a component is the compiler's,
so nothing is written inside a name and no ', )' is left; an entry point that declares states
already gets the rest after them
- a program's module named like a package gets <Name>AppState; a program's own file its own state;
a friend module's files go by directory; a package's settable var stays state
- it writes only under the programs and directories given (and runtime/ with --runtime), and
refuses the whole run naming any other file that would have to change
- a name a package already moved into its state is rewritten through it; a read of the runtime's
var through the runtime function that answers it (gl_w: gl_width())
- a state's instance supplied by the runtime is not a uses reference
- tests: state/component, rejected/state_component_ro, rendering/ui_render3d, migrate component
and foreign cases
