AVFAudio keeps a 64-byte AudioQueueOwner for good on every AVAudioPlayer play
after the clip has finished - measured one a play, whatever is called around
it (prepareToPlay, pause, no rewind) and still there after the player is
released; a stop before the play made one every time. The windowed walk showed
it as AudioQueueOwner 73 -> 87 in a minute.
A sound is now decoded once into a PCM buffer and played by a voice of its own
on one shared engine: a player node (the buffer scheduled again on each play,
looping for -1), a varispeed (the rate) and a small mixer (volume and pan).
snd_playing compares the uptime clock with the end worked out when the clip was
played (asking the node where it is made two AVAudioTime objects a call), and
snd_play drains an autorelease pool of its own. The C interface is unchanged.
A harness driving snd_* directly (400 plays past the end, the playing flag
checked during and after each, a loop and a stop, the setters) holds the heap
flat to a block and gets the flag right 400 of 400; the windowed valley
compiles and links against it.

input_device_commit made words(6), words(IN_PADS * 6) and words(IN_TOUCH * 3)
every windowed frame and dropped them - the walk's exit scan found 7 MB of
them unreachable after ten minutes (headless never polls devices, so no
headless run saw it). They are made in in_init with the rest of the input
state and filled in place. input_text's UTF-8 buffer is the state's too,
sized for the most the window hands over (64 units, four bytes each): it
made one per keystroke.

render3d: shadow_fit, water_reflection_pass, layer_partition_lods and the
GPU cull's scratch are made with the state; v3_dist is scalar; the pushes
into lists sized at start-up, the caps probe, the table growth, the loads
and the constructors declared with their bounds (one statement a line);
the renderer's name made once with the device; the two error messages
given back; the dead lupine models removed.
runtime: a component's text is held interned in its value cell (one copy
per distinct text), so the getter's own text goes with its frame instead
of being kept by ludic.ui's model - 80 of the 83 keeps.

Plan 25.1c: vk_mac.ll's @lvk_ac (posix_memalign under a 16-byte header of scope/offset/size, atomic
counters) passed at every render3d create/destroy (49 sites; the caps probe keeps its own null pair);
lvk_ac_bytes/_peak/_allocs/_scope_bytes for the fence, Vk.alloc_bytes. vk_win.ll: null and 0.
MoltenVK 1.4.2 counted 0 live bytes through them in steady. Fence findings: gvk_pipeline freed its 17
create infos (and reuses one bufs list); actor_init fills ac_spare with 512 records (actor_fresh,
m4_new, v3_new at first placement in play). Compiled, not run (the user's call).

The encoder appends into RtJsonState's buffer (grown only past the biggest document yet): ints and
Q16.16 fixeds written as digits in place, floats through string() and freed. Json.encode copies the
answer out once; Json.write_file hands the buffer to Fs.write_text (.tmp + rename) and keeps nothing.
json_saves.ludic: exact text, the file equals encode, parse round-trips, 1000 saves grow 0; clean

Text/Path/Mime/DateTime/Os dirs are fresh and Text frees a fresh argument. Reseeded.

- Json.free_all (value_free_all): a parsed tree's nodes, lists and strings. render3d frees each
glTF document that way at the next load; the names kept out of it are copies (a primitive's
material, a skin's joints, an animation clip's name in ludic.anim) - a model's strings were
~640 KB left behind per load
- jp_number made a digits list per decimal in a document and never freed it
- gvk_layout_id matches a mesh's layout as numbers in a scratch made once, against the layouts
known end to end; a new mesh no longer builds a key string
- gvk_mem_new puts a new block into the record of one given back rather than appending, so a
buffer made again every few frames no longer grows the block lists
steady.ludic adds a glTF parsed and freed whole 200 times: 0 bytes (38,400 before the digits fix),
beside the buffer path and the frame, still 0. A model loaded and let go still keeps ~2 KB a round
(texture and buffer handles are not reused yet); it is bounded at 8 KB a round.

gvk_mem_new made a one-slot []pointer per allocation, and turned the requirement's size and
alignment into strings to read them as ints; gvk_list_drop_last rebuilt the spare-record list to
drop its last entry; gvk_mem_id did the string round trip on every free. One slot is kept
(gvk_map_slot), int() truncates a long, the spare list pops. Every Text.to_int(string(x)) in
render3d is int(x) now.
Vk.heap_bytes() (vk_mac.ll: malloc_zone_statistics' size_in_use; 0 on Windows) and
examples/rendering/steady.ludic, in the suite: a buffer released and made again 5000 times and
600 whole frames gain 0 bytes each - the allocator before this, 1,120,000 over the 5000.

native/build.sh builds MoltenVK v1.4.2 from its pinned, checksummed tag (its dependencies at the
commits its ExternalRevisions pins), thinned to arm64, id @rpath/libMoltenVK.dylib, signed ad hoc;
its licence goes in native/LICENSE-MoltenVK. Every render3d program links it through its rpath -
the package's lib/ while developing, Contents/Frameworks in a bundle, where ludic bundle puts and
signs it - and vk_mac.ll also looks for @rpath/libMoltenVK.dylib (after an SDK loader, so the
validation layer still stacks in development). The suite's SDK stand-in (vk_env) is gone: the
render checks draw on the MoltenVK the package carries. gpu_is_gl() removed; nothing calls it.

- every texture upload malloc'd a CPU copy of its pixels and never freed it (236 MB over the
valley's boot, and again for every model loaded later): the pixels are converted straight
into the mapped staging buffer
- the per-level and per-layer views gvk_view_of made outlived their texture, and on MoltenVK a
view keeps its Metal texture alive: a released texture takes its views with it, and the cache
is keyed by numbers instead of a string built on every call
- the Vulkan structs filled for a draw, pass, barrier, descriptor set, buffer, allocation or
upload (about sixty call sites) come from a reused 1 MB scratch ring (gvk_tmp)
- the descriptor-set cache and the retired buffers are emptied in place, not replaced; the grass
cull's dispatch arguments are made once
- macOS drains an autorelease pool each frame (Vk.frame_pool, lvk_frame_pool in vk_mac.ll)
- R3D_VK_PROF reports Vulkan objects made and destroyed by kind, and every cache's length
- examples/rendering/smooth presents through render3d, so it runs on Vulkan too
The full valley on headless Vulkan loads to 2.18 GB and holds (it passed 8 GB while loading
before). ludic-dev test 305/305, selfhost-test 33/33.

The seeded random numbers lived in the ECS runtime, so a tool or a
program of test blocks got "unknown function rng_range". They are
runtime/native/rng.ludic now, spliced on Random.* or a bare rng_*/seed
call nobody defines, and imported by core.ludic for a game. A bare
value_*/json_* call nothing in the program defines splices the value
tree the way Value.* does. Reseed.

A game no longer writes a host:
- The runtime reads Input itself: focus and keyboard navigation (Tab, arrows, Enter/Space,
autofocus), the pointer (hover, :active, click on release, drag), and scroll boxes with the
wheel, a draggable scrollbar, clipping and scroll-into-view.
- HTML's controls are built in (button, checkbox, radio, range, select, text, key capture), made
of plain parts a stylesheet styles, each reporting with on-change and event.value.
- ludic.ui/render3d.ludic draws with render3d's overlay: textures, named atlases (icon:NAME),
nine-slice border-image, rounded rects and rings, clipping, and a scale.
- Hooks for the program's language, sounds and clock (ui_translator, ui_sounds, ui_clock).
- ui_dev: hot reload, errors on screen, LUDIC_UI_DUMP.
- CSS:
- colours as #rgb / #rrggbbaa / rgb() / rgba() / names;
- border-radius and outline (following the radius), box-shadow, background-image and a tinted
border-image;
- group opacity, @keyframes / animation, transition;
- :focus, :focus-visible and :focus-within.
- HTML mixed content, and boolean attributes.
- render3d gains tex_width / tex_height, and the XML reader keeps text runs in order.

- Natives: ui_native(tag, measure, draw) makes an element the program draws itself; ui_fire

- + and ~ combinators, :nth-child(an+b), :checked, :active.
- Developing: errors with file:line, ui_errors(), ui_reload() keeping state, and an

A `view Name { field = x; function q(..); on e(..) }` declaration is the one bridge between a
program and its UI: it writes view_<name>() -> UiView, whose model is a Value of every field and
whose call runs a query or an event by name.
ludic.ui is a template runtime:
- HTML-shaped XML screens and components, loaded at run time;
- {expression} bindings, if/else/each, props, slots, per-instance state;
- on-press / onclick actions (event, set, emit);
- component libraries (export="true", <import src as>).
Styling:
- stylesheets in <style> or importable .lss files (@import);
- CSS selectors (#id, .class, [attr=v], descendant and > combinators, :hover, :disabled,
:first-child, :last-child, :nth-child, :not) weighed by specificity;
- the box model and flex under CSS's property names.
Also:
- default parameters, and positional-then-named calls;
- Value gains a float kind;
- a function shadowing a runtime one is refused;
- an index is evaluated before the slice is read;
- runtime errors name the right file.

The typed buffers are slices: words/floats/fixeds/doubles/pointers(n) make
zeroed, bounds-checked []int/[]float/... and the type names mean them. buffer(n)
is a []byte, with text_of, Fs.read_bytes/write_bytes and view(xs, start, n).
bytes(), indexing a raw pointer or bytes, free, resize, Memory.*, raw file calls,
data_of and C externs are refused outside unsafe { } / unsafe function, and a
project's own files may write unsafe only with --unsafe; the runtime and packages
are the platform. A slice passed to an extern goes as its data.
What the change found: Sync's atomics on a slice header, words(n) uninitialised,
input's fixed axes in ints, truetype's fixed outlines as ints, skin matrices
typed int, gl_shader's source table made from raw bytes. render3d gets safe
entry points (safe_api.ludic). Rendering is byte-identical; a frame costs the same.

`alias meth(labels) = target` in a namespace block makes Ns.meth a call to
target with those labels (the target's own parameter names without a list). The
engine's 41 table-driven namespaces - 438 methods: Http, Udp, Process, Json,
Value, Screen, Input, Audio, World, Tiled, ... - leave emit_ns_call for
runtime/native/namespaces.ludic, spliced into every program; 532 lines of
compiler go and the seed shrinks by 23k lines of IR. The game's IR is byte
identical. The checker checks an alias call's arguments against its target.
Still built in: the inline namespaces (Math, Text, List, Vector, Color, Time,
Date, ...) and the methods that pick a target by argument type.

selfhost/check/ walks every function, the entry, tests, globals' initializers and
@On listeners with real scopes, and refuses mixed number kinds, text and numbers,
two record types, mismatched slices and fn types, wrong argument counts, wrong
returns and wrong push elements - every mix-up at once, each at its line.
LUDIC_CHECK_REPORT=1 lists them by category. pointer stays untyped (L7's).
What it found is fixed: render3d's HDR scan calling the float-bits extern f_lt
with floats; ludic.shooter's right-stick aim overflowing past half a push;
prof.ludic storing longs in []int; extern arguments now coerced to their
parameters. Text-returning runtime functions say string; Assets.ready says bool.

Input.text, App.monitor_count / window_to_monitor / window_fixed,
gl_sleep_us, and the grass and collide changes, uncommitted on main and
depended on by the game; carried here so the language work starts from
what the game actually uses. main's working tree is untouched.
scrollingDeltaY is a double and the Cocoa event pump truncated it to an int per EVENT
before accumulating. A trackpad or a Magic Mouse sends a stream of fractions of a line,
every one of which truncated to zero, so the wheel was dead; a notched mouse sends three
to ten lines at once, so it jumped. The fraction is accumulated now, a precise delta is
scaled from points to notches, and the remainder carries to the next frame.

The platform gave these keys no code at all, so a game's rebinding screen could not take
one and nothing said why. Windows asked the active layout what they type and got nothing
(w_vk_char answers 0 for a key with no character); macOS let them fall through to
charactersIgnoringModifiers, which reports NSF1FunctionKey and its neighbours at 0xF704
and up - outside the 256-bit held set either way.
w_keyval and ev_keyval now name them, with the same codes on both: 132-143 F1-F12,
144-149 Home / End / PageUp / PageDown / Insert / Delete, 150 Caps Lock, 152-161 the
numpad digits, 162-166 its * + - . and /. The numpad's Enter is Enter.
Key.F1, Key.Home, Key.Numpad0 and the rest fold at compile time, and Input.key_label
names them without asking the layout - a key that types nothing is called the same thing
on every layout.
examples/library/input_typeless_keys.ludic covers the codes, the names, the held set and
the press edge; 150 passed in ludic-dev test, 33 in selfhost-test.

The runtime opens a game's window before main, titled with the program's name, and
gl_open attached to it without passing its title on (render3d's gvk_open called win_open,
which returns early on Windows and opened a second window on macOS). win_set_title in
cocoa.ll / win32.ll (setTitle: / SetWindowTextW, UTF-8 -> UTF-16; a no-op without a window,
stubbed headless) retitles it from gl_open, and win_open on an open window retitles it on
both platforms.

Http.save_to streams a response body into a file (NSURLSession with a run-time delegate

The Windows runtime keyed the held set by the character MapVirtualKeyA gave a
virtual key, so a game's WASD belonged to whatever the active layout put there,
and with an input method on every letter arrived as VK_PROCESSKEY. The typing
block is now read from the scancode (the arrows, numpad and F-keys still by
virtual key); macOS reads keyCode the same way. Input.key_label(key) names a key
in the player's own layout (Windows) or as its US character elsewhere.
Verified on Windows with SendInput into a live window: VK_Z carrying W's scancode
holds 'w', VK_PROCESSKEY carrying A's holds 'a', Caps Lock changes nothing.

NVIDIA Streamline's interposer exports none of VK_KHR_acceleration_structure's
commands, so ray tracing looks each up per device with vkGetDeviceProcAddr and
calls it through a pointer: create (four pointers -> result), destroy (device,
handle, allocator), build sizes (device, type, info, counts, sizes), the
command-buffer build (buffer, count, infos, ranges) and the device address
(device, info -> u64). Both runtimes assemble; nothing uses them yet.

The chunked grass path draws each chunk as one mesh-shader dispatch when the
setting asks and the card has VK_EXT_mesh_shader: work group y is a tile, x a
batch of 16 of its blades, and a blade the placement, density, frustum, water
or slope tests reject emits nothing - the instanced path still runs its eight
vertices to a degenerate position. grass.mesh generates the same blades as
grass.vert (grass_blade_mesh(4)'s rows, the same hashes, sway and lighting
normal), capped at the instanced path's 65535 a tile.
Vulkan: VK_EXT_mesh_shader with meshShader, and maintenance4 (glslang's mesh
stages declare LocalSizeId); vkCmdDrawMeshTasksEXT looked up per device, as the
Streamline interposer exports none; a *.mesh program's pipeline takes the mesh
stage and no vertex input, its bindings the mesh stage bit. gpu_has_mesh,
gpu_draw_mesh_tasks; r3d_mesh_grass and R3D_MESH_GRASS / R3D_NO_MESH.
bin/ludic-dev rebuilt: the committed binary predated the shader tool's mesh
support and compiled grass.mesh as a vertex stage.

ludic-dev shaders: a variant whose first file is *.mesh compiles that stage with
glslang -S mesh for Vulkan 1.3, without the vertex stage's depth-remap wrapper
or invariant gl_Position (a mesh shader writes an array of positions and
remaps depth itself). Its SPIR-V keeps the .vert name, so the manifest and the
loader are unchanged. The 51 existing programs build identical SPIR-V.
runtime: lsl_call_piii(fn, ptr, i32, i32, i32) calls a command-buffer command
through a pointer. NVIDIA Streamline's interposer exports no
vkCmdDrawMeshTasksEXT, so it is to be looked up per device with
vkGetDeviceProcAddr. Both runtimes assemble.
Nothing uses either yet.

- `fn name` names a top-level function as a value (E_FNREF, lowers to @fn_<name>); the worker

compare-and-swap. Linked only into programs that use Job/Promise/Sync, by `ludicc -o`,
`ludic build` and the test suite's build helper.

- gpu_select takes Vulkan for a window on Windows; gvk_init asks for VK_KHR_surface,
VK_KHR_win32_surface and VK_KHR_swapchain when the renderer will present. A window elsewhere
stays on OpenGL with the reason.
- gvk_open opens the window without a GL context and makes the screen images at its client area;
gvk_swap_make builds the swapchain on the Win32 surface (FIFO with vsync, mailbox or immediate
without) and rebuilds it when it is out of date, suboptimal or the window changes size.
- gvk_present blits the screen image into the acquired swapchain image, flipped (the screen keeps
OpenGL's bottom-up rows), and presents it.
- Samplers pointed at a texture unit with u_i and then fed by binding units - the actors do this -
read that unit's texture; on Vulkan they drew with the white stand-in (the tent, the log, the
chair, the workbench).
- gl.ll carries a weak win_gl_drawable for headless macOS builds.
On the RTX 3070 Ti the windowed build runs the valley through Vulkan at 3840x2160 with the HUD and
the frame-rate readout (16 fps: every upload still waits on the frame, and buffers are
host-visible). The headless Vulkan frame is unchanged; OpenGL frames byte-identical at the five
viewpoints with 59 self-tests passing. The actor fix is compiled and OpenGL-verified, not yet
seen on the PC; blades at the grass's middle distance still draw black on Vulkan.

win_native_window / win_native_instance hand a Vulkan swapchain what it is created on: the
HWND and module instance on Windows (VkWin32SurfaceCreateInfoKHR), the game's view on macOS.
Headless builds define both as null (weak on macOS, so a windowed link keeps cocoa.ll's), so
code that asks for them links everywhere and simply finds no window.

ludic-dev vkgen reads vk.xml into runtime/native/vk_api.ludic (constants, every struct's
<Struct>_sizeof and <Struct>_<field> offsets, one extern per command) and vk_thunks.ll.
Every size and offset was compiled against the SDK's C headers; `ludic-dev test` checks the
tracked files against the registry wherever the Vulkan SDK is installed.
vk_win.ll (vulkan-1.dll) and vk_mac.ll (libvulkan.1.dylib, MoltenVK) open the loader at run
time, so a program built with Vk.* starts on a machine without Vulkan. ludicc and ludic
build link both for any program that uses Vk.*. The seeds are regenerated for the new
compiler.
vk_probe reports what a machine's Vulkan can do; vk_compute dispatches a Slang compute
shader and reads the picture back, clean under the validation layer on an RTX 3070 Ti and
on an M4 Pro through MoltenVK.

The delta was this frame's position minus the last, and the last started at 0,0, so the
first frame reported the cursor's whole distance from the corner as motion. A cursor-mode
change did the same, switching between a locked cursor's virtual reticle and the real
cursor. Maroon Lake's camera adds mouse_dy to its pitch and came up pointing at the ground.
examples/library/input_mouse_rebase.ludic covers both cases, plus ordinary motion and
re-setting the mode already in force.

http_win.ll implements http.ll's hs_* contract over WinHTTP: the request is a
record built on the game thread, the whole exchange runs on a worker thread,
TLS uses the system's certificate checks, and headers are answered from the
kept request handle. ludicc links it with winhttp instead of refusing Http.* on
Windows.
win32.ll decodes the splash and App.set_icon images with WIC (ole32): the
splash is a topmost borderless window at the artwork's size in points times the
display scale, composited over its background colour; the icon becomes an
HICON set on the window now or when win_open makes one.
Verified on the PC: examples/library/http.ludic prints its expected output, a
real GET to https://git.workshopsoft.io/ returns 200 with its body and
Content-Type, and the bundled Maroon Lake shows its splash centred at launch and
its icon in the title bar.

w_fit_scale turns the display's DPI into a whole-number scale (96 -> 1, 168 and
192 -> 2), brought down until the window fits; win_open and win_gl_resize size
the client area with it, win_gl_scale reports it the way cocoa.ll reports the
backing scale, and the mouse still arrives in the game's own units.
Verified on a 3840x2160 panel at 175%: windowed gl_triangle's 640x360 window
draws a 1280x720 frame.
