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.
ludic-dev test 306/306 with no Vulkan SDK in the environment.

- 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.

- 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

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.

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.

vk_sl_prefer(1) before Vk.open() makes the Windows loader try sl.interposer.dll
beside the executable and fall back to vulkan-1.dll. Thunks for the sl* exports
and for calling feature functions from slGetFeatureFunction; macOS stubs.
Verified on an RTX 3070 Ti: slInit eOk, DLSS, DLSS-RR, Reflex and PCL supported,
DLSS-G reports no supported adapter (needs RTX 40).

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.
