Process.spawn/poll/kill/free - non-blocking child processes with no shell: posix_spawn on
macOS (process.ll), CreateProcessW with MSVC-quoted arguments and no console window on
Windows (process_win.ll), linked only when a program uses Process.*.
Http.save_to streams a response body into a file (NSURLSession with a run-time delegate
class on macOS, the WinHTTP read loop on Windows); Http.received / Http.expected report
progress while it is pending. Freeing a pending request cancels it and parks the slot
until the worker has finished.
App.window_hide / App.window_show take the game's window off the screen and back without
closing it; the run goes on while hidden. Docs, examples, tests and a changeset.

emit_bin_vals lowered every pointer-typed ==/!= to @lp_str_eq, so two
distinct records compared their bytes up to the first zero byte. Content
compare now needs both sides to be text (string, or the untyped
pointer/ptr runtime code carries text in); other references use
icmp eq ptr, and string vs a non-text reference is a compile error.
Adds selfhost/tests/identity.ludic; both seeds regenerated.

`float` (32-bit) and `double` (64-bit) with + - * / %, comparisons and unary minus.
Decimal literals take their type from context and stay `fixed` elsewhere; int and long
promote implicitly (LUDIC_WARN_FLOAT_PROMOTE=1 lists every promotion). float(), double(),
int(), long() and fixed() convert; floats(n)/doubles(n) buffers; float fields, globals,
constants and parameters; Math.* computes in float for float arguments; string/print
write the shortest round-tripping decimal; float_bits/float_from_bits expose the bits.
@deterministic code may not use floats. The f_* runtime helpers stay as they are.
Editors know the new type words; the JetBrains plugin is 1.5.0.

A reflecting body is clipped to its ellipse like every other unless it is an
unbounded sea, so a map whose reflection belongs to its lake (Maroon Lake, once
its sea sits below it) does not draw that lake's level over every hollow in the
survey. The terrain's wet shore and its forest and scree gates read the carved
lake's line inside its outline (u_lake), the rule grass already used. SPIR-V
regenerated.

Every R3D_* read goes through r3d_env_has / r3d_env (env.ludic): a headless
build honours them as before, a windowed build only when R3D_DEV is set to
anything but "0", so a shipped game never reaches a debug view, feature kill,
file writer or hardware fake. Documented in docs/SHIPPING.md.

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.

r3d_hdr_calibrate(peak, paper, black) feeds the tonemap's and the overlay's HDR10 variants and
the display's HDR metadata; ov_hdr_nits draws a calibration patch at a number of nits.
gpu_caps_probe asks the running Vulkan renderer's instance instead of making and destroying a
second one under Streamline's interposer, which left the next swapchain rebuild calling address 0.
The overlay gets an HDR10 variant, and the tonemap brightens HDR highlights by one factor rather
than per channel.

A chunk's dispatch was sized for its largest tile, so the far tiles beside a
near one ran thousands of empty invocations: 9.8 ms of grass at 4K on an RTX
3070 Ti. One dispatch per tile, sized to that tile, brings it to 5.0 ms - still
three times the chunked path's 1.7 (36 fps against 41), so GF_MESH_GRASS is not
implemented yet and the Advanced row says a coming update.

- sky_start_yaw: a game that turns the sky at boot sets it before r3d_init and the image-based light
is baked once at that yaw; sky_set_yaw to a yaw already baked bakes nothing.
- terrain_init_step: the height field and normals, the sun shadow, the materials, the patches and
programs as separate steps; r3d_load_count is 8, so a loading bar moves through the terrain (half
the start-up) instead of jumping over it. terrain_init runs the four in a row as before.
- The per-cascade actor cull centres its sphere at half the model's height and sizes it by the
larger of height and radius: centred at the radius, it dropped a head at a cascade's edge (11 px
in town, found by the drawstats comparison). Lake was byte-identical before and after.
OpenGL frames at the five viewpoints unchanged; the game's 59 self-tests pass.

- r3d_open opens the window with nothing baked; r3d_load_count / r3d_load_step run the rest (sky
and light, terrain, shadow and screen targets, cover and actors, grass) so a game can present a
loading frame between them. r3d_init is the same calls in a row.
- sky_set_quality(width): the prefiltered sky light at 256 / 512 / 1024, baked again.
- post_set_msaa(samples): multisampling on OpenGL, remade in place (post_msaa_live is false on
Vulkan); post_free frees the multisampled framebuffer too.
- STREAM_BUDGET_US is a variable; r3d_fog_scale multiplies the fog the day sets.
- Vulkan buffers carry UNIFORM_BUFFER usage: the frame's ring is bound as uniform buffers and was
created without it (VUID-VkWriteDescriptorSet-descriptorType-00330, found on MoltenVK).
OpenGL frames at the five viewpoints unchanged; the game's 59 self-tests pass.

- r3d_set_anisotropy(level) updates every mipmapped texture already loaded (OpenGL parameter,
Vulkan sampler record), not only later uploads; the game's setting never reached the scanned
materials, which load before the settings are read.
- shadow_set_res(size) remakes the cascades at 1024 / 2048 / 4096 (shadow_res replaces the
SHADOW_RES constant); lighting.glsl reads the texel size from the map, so OpenGL frames at
2048 are unchanged.

- `fn name` names a top-level function as a value (E_FNREF, lowers to @fn_<name>); the worker
entry point for Job.parallel_for, which checks it takes (int, pointer-like) and returns void.
- runtime/native/threads.ll (pthreads) and threads_win.ll (Win32 SRWLOCK/CONDITION_VARIABLE): a
pool of one worker per core but one, parked between batches; every thread claims chunks by
compare-and-swap. Linked only into programs that use Job/Promise/Sync, by `ludicc -o`,
`ludic build` and the test suite's build helper.
- Sync.* is real: native mutexes, atomics as cmpxchg retry loops (neither clang takes atomicrw,
the PC's rejects seq_consistent), mutex-guarded channels, Sync.cpu_count from the OS.
- spawn/despawn on a pool thread stop the program with a located panic.
- examples/library/threads.ludic and its test; docs for fn, Job.parallel_for, Job.is_worker.
- Reseeded (bootstrap-cfree: out.ll == seed.ll). 141/141 on macOS; jobs, threads and the guard
pass on Windows from the reseeded Windows seed.

Render state (depth, blending, culling, colour writes, alpha-to-coverage, depth bias,
scissor) and uniforms go through gpu_* / u_* and nowhere else; OpenGL state is cached and
only changes reach the driver. Frames are bit-identical to before at the fixed viewpoints.
R3D_GFX=gl|vk or gpu_request chooses a backend, falling back to OpenGL with a reason.
gpu_caps_probe() asks Vulkan, on Windows, for the 1.3 floor, ray tracing, mesh shaders, the
NVIDIA RTX generation, Reflex and HDR colour spaces, for a game's settings to grey out what
a machine cannot use; R3D_CAPS pretends to be a given card for tests.

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.

The queue was only emptied by the next outline_model call, so the last highlighted tree kept
its rim after the player looked away. r3d_frame now calls outline_frame, which drops a batch

ov_text, ov_text_w and ov_text_wrap decode UTF-8 instead of drawing bytes 32-126. font.json
may list the atlas's code points in "codes"; an atlas without it reads as before (ASCII
from "first"). A missing code point draws as '?', a cut-off sequence as one '?'.
overlay_font(dir) loads or swaps the atlas at run time, for a language with its own script.

Needle-card crowns are many cut-out quads deep and a discarding shader turns early depth
rejection off, so every card behind the front one ran the full lighting shader. The near
tree LODs now write depth first (depth.frag, the same alpha coverage test), terrain under
them is rejected before shading, and the lit pass draws them with no discard and an equal
depth test (invariant gl_Position). R3D_NOPREPASS=1 restores the old path.
Dense forest on a Windows PC: 61 -> 78 fps at 3840x2160, 116 -> 164 fps at 1920x1080.

http_link_flags grepped the IR for "@hs_", which every program's header
declares, so `ludic build` linked the HTTP transport and Foundation into
everything - invisible on macOS, a failed link on Linux, where it broke four CI
cases (ludic run, the installed layout, ludic new, the seed build through
`ludic build`). It now looks for a call to hs_send: examples/library/http.ludic
has one, snake.ludic (which still declares ten @hs_ names) has none.

The asset-pack boot calls _NSGetExecutablePath, which glibc does not have, so
the Linux link of the compiler seed failed in every CI job - build-and-test,
cfree-fixpoint and every publish run - since packs landed. The last release CI
created was v0.7.0. The Linux shim now defines it over /proc/self/exe.

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.

The CLI's shell commands go through shell(), which is run() on POSIX and a
scratch script handed to Git for Windows' bash on Windows (exit codes read
directly there). compile_app links through `ludicc -o` on Windows, ludic run
starts the .exe, and ludic-dev build and ensure_ludicc assemble
selfhost/ludicc.win.seed.ll, which ludic-dev reseed now writes beside the
macOS seed. ludic bundle makes build/<name>/ with a GUI-subsystem exe carrying
the .ico beside `app icon` as an llvm-rc resource, game.lpak and packs.index;
ludicc gains --gui and --link, and quotes its whole link line for cmd.exe.
Verified: ludic-dev test 135/135, selfhost-test 32/32; on the PC a checkout
bootstraps from the Windows seed, ludic-dev build makes the toolchain, and
`ludic bundle` makes build/Maroon Lake/, which runs from its own folder.

AppKit gives kVK_Delete (51) the character NSDeleteCharacter, 127, which is
what both ev_keyval (the held-key set) and win_poll (the per-frame key)
received, so Key.Backspace, which folds to 8, never matched. Both now map key
code 51 to 8.

compile_app linked gl.ll when the IR named @lgl_* but never http.ll and
Foundation for @hs_*, so examples/library/http.ludic failed to link under
`ludic build` on every hs_* symbol while `ludicc -o` built it. http_link_flags
greps for @hs_ and links them in both modes; ludic-dev test now builds the
example through `ludic build` as well.

The arrow Key constants folded to the codes of w/s/a/d, which is what the
per-frame key reports for an arrow, but cocoa.ll has always stored an arrow in
the held-key set under 128-131. So Input.key_down(Key.Up) read the W bit and
Input.move_i's arrow half never moved anything. Input.key keeps its WASD alias,
so games comparing it with 'w' (snake, chronorift) still take the arrows.
New example input_arrows.ludic, checked by ludic-dev test.

audio_win.ll implements audio.ll's snd_* contract over XAudio2 from IR: a
source voice per clip, restart on play, LoopCount for loops, SetVolume,
SetFrequencyRatio and a balance pan through SetOutputMatrix, with the COM
slots taken from the SDK's xaudio2.h. Clips are RIFF WAVE read through
lp_pak_open (weakly referenced), so a packed sound loads directly. ludicc links
it with xaudio2 and ole32, and silences xinput.lib's importeddllmain warning.
Verified: ludic-dev test 135/135, selfhost-test 32/32; on the PC a harness
loads, plays, pans, loops and stops clips, and Maroon Lake windowed reports
"sound: 31 of 31 clips loaded".

win32.ll implements cocoa.ll's contracts over user32 and xinput: the message
pump, the held-key set and frame key in Ludic codes, the mouse with raw input
for cursor mode 2, clip-based cursor modes released on focus loss, XInput pads,
and the software framebuffer present. win32_gl.ll puts the WGL 4.1 core context
on that window (vsync, borderless full screen); gl_win.ll's context code is now
lgl_wgl_core, shared with the headless hidden window, whose win_gl_* stubs move
to gl_win_nowin.ll. audio_win.ll links Audio.* silently for now.
Verified: macOS fixpoint, ludic-dev test 135/135, selfhost-test 32/32; on the
PC gl_triangle renders identically headless and in a real window, and Maroon
Lake builds windowed and runs a playtest to frame 240 in the desktop session.

gl_win.ll creates a hidden-window WGL 4.1 core context and carries gl.ll's
float/memory helpers, with ldexp and QueryPerformanceCounter in place of the
libSystem calls. glgen now also writes gl_thunks_win.ll: the same 478 thunks,
calling through pointers that @lgl_win_load fills from wglGetProcAddress (and
opengl32.dll for GL 1.1). ludicc links the pair against opengl32/gdi32/user32
on a Windows target.
Verified: gl_api.ludic and gl_thunks.ll regenerate byte-identically, ludic-dev
test 135/135, selfhost-test 32/32, and headless gl_triangle on an RTX 3070 Ti
matches the macOS frame to within one level per channel.
