Every lit program blends toward the horizon colour (the prefiltered sky with the sun's inscatter,
so it carries the day's grade); the sky's horizon band is pulled to the same colour, wider the
closer the wall. The far plane, scatter and stream cull reach and the shadow cascades are clamped
to the wall; the reflection pass shares the shaders and the cull. 0 is off: every branch is gated
on u_fog_wall > 0 and r3d_reach hands back the far it was given. R3D_FOG_WALL=<m> for a shot.

The valley self-test died after the Lamar swap, loading Maroon's pine LODs:
gvk_fr_blk (the device suballocator's free ranges) grew past its @max(4096).
Nothing failed to coalesce: a range was carved at the buffer's bare size, so
what was left after it started unaligned and the next buffer, rounding its
start up, left a sliver before it that no later buffer could use. One host
block held 3,968 small buffers and 3,718 free ranges between them - 496 KB
free in all, 133 bytes a hole. Those merge away when a neighbour is freed, so
nothing leaked; the count simply rose with live buffers.
gvk_mem_new now carves `span`, the size rounded up to the alignment, and
records it as the allocation's length, so a free gives back exactly what was
carved and the rest of a range always starts aligned.
The same repro (the lab's `tests` scene, headless, a fresh test root): the list
never reached 256 slots (it passed 4096 before), the run completes (exit 0),
LAMAR OK and THINGS OK. r3d_small was 0 throughout, as ECS said.

A small window (r3d_small: the launcher's UI process) draws its interface flat
and tests no depth, but gvk_screen_make gave it a 32-bit depth image the size
of the screen - 8 MB at 1920 x 1080. In small mode the screen has none: the
pass and a clear with no depth attachment already leave depth alone (clearing
DEPTH_BUFFER_BIT with no attachment is skipped), and pipelines follow the
pass's formats.
With the launcher's own 1920 x 1080 backdrop (maroon-lake game/launcher-small),
the launcher window measured 378 -> 295 MB of footprint at 25 s; its headless
shot (R3D_SMALL=1, so no depth) differs from the unchanged build by 0.279% of
pixels, the resized backdrop, and two runs of each are identical.

The atlas is white glyphs on alpha and the overlay reads only the coverage,
but it was uploaded RGBA8: Maroon Lake's 3072 x 2688 atlas was 43 MB of Metal
memory with its mips, the largest single thing in the launcher window.
overlay_font now keeps the alpha alone as R8 (ov_font_tex; any other PNG
shape is uploaded as before) and overlay.frag reads .r - the white fallback
texture reads 1 there as it did from .a.
Launcher window, graphics regions: the atlas 43.0 -> 11.5 MB; process
footprint at 25 s 402 -> 378 MB. The headless launcher shot is identical to
the unchanged build's (0 pixels differ; two unchanged runs differ from each
other by 1.69%, and the new one by the same against them).

With one frame in flight, a buffer filled every frame (the interface's vertex
buffer, ov_vbo) was still being read by the frame on the GPU when the next
frame filled it, so gvk_buf_reserve released it and made a new VkBuffer and
its memory every frame - and every new buffer took a prime submit of its own.
Each handle now keeps a second buffer (gvk_bsp_*): a busy one swaps with it
when it is free, else the busy one becomes the second and one new buffer is
made; releasing a handle lets both go.
The launcher window (--launcher-ui, R3D_VK_PROF, per 120 frames): buffers
made/destroyed 120/120 -> 0/0, command buffers 240 -> 120 (one a frame). Its
footprint does not move with it (358 MB at 40 s, both): the churn was work,
not memory.

Set before r3d_open: the frame's uniform ring is 2 x 4 MB (was 2 x 64), memory blocks are 8 MB with
anything over 4 MB on its own (was 64 and 16), and the descriptor pools are an eighth of a world's.
Maroon Lake's launcher window draws a picture and text and never becomes the game; its launcher home
and Settings page draw pixel-identical on it. The full-size path is unchanged (steady: STEADY OK).

gvk_swap_make freed none of what it made - the surface caps, the count, the
format and present-mode lists, the create info, the handle out - and replaced
gvk_swap_images without freeing it: a few hundred bytes every time the window
changed size, went to or from Retina, or the chain came back suboptimal. Each is
now freed on every way out (the minimised return and the failed create included),
and the old image list before the new one is made.
A windowed memory walk built against it (main 5ee600d2, 300 s, the autopilot
opening screens every 6 s): footprint 2816 MB at 120 s, 2818 MB at 300 s; the
fence judged 0 frames kept.

gvk_sc_make's cache (program + bound textures -> a set in the kept pool) evicted
nothing until the pool's 8192 sets filled. A texture freed - a photograph's
thumbnail, a wall frame, any picture a screen loads - left its entries and their
sets behind for good, since its handle's generation moved on and the key could
never match again: 262 KB over 12 minutes of the user's play, and bound only by
the pool, hours away.
gvk_tex_release counts the releases (gvk_sc_dead); at GVK_SC_DEAD_MAX (256) the
next frame's start resets the kept pool and empties the cache (gvk_kpool_reset,
which waits for the frame in flight), and each draw still in use makes its set
again the first time it is drawn - the budget is the live combinations plus at
most 256 textures' dead ones. The declared reason on gvk_sc_make was the
swapchain's, copied; it now says what the cache is and what bounds it.

Every tree on the map was drawn as an impostor card into all the cascades,
the near two included, whose receivers (within 60 m) are shaded by the near
trees' own LOD2 meshes cast beside them. The cards now cast from cascade 2 on.
Aspen view, same main and foundations, 240 frames, with the figure capsule:
shadow instances 323,587 -> 202,743; shadow GPU 4808-4942 -> 4579/4578 us;
median frame 17200-17693 -> 17178/17205 us. The look held: shots of the view
taken twice a side are identical within a side (0.00% of pixels past 8) and
differ by 0.04% across (every pairing).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
In cascades 2 and out (receivers from 60 m) a skinned figure of more than
eight pieces - a dressed person, up to 86 of them - casts one capsule its own
height (radius 13% of it) instead of every visible piece: past 60 m nobody
can tell a garment's shadow from the body's. Animals (a piece or two), rigid
props and the near two cascades are unchanged. The capsule is made once.
Aspen view, same main (30ec1722) and foundations (15f1020), 240 frames, twice
a side: shadow draws 1889 -> 1799; shadow GPU 4808/4819 -> 4710/4714 us;
median frame 17200/17221 -> 16910/17128 us. Most of the far cascades' actor
draws turned out to be rigid props (the census's "skinned" counts draws, not
actors), so this is the smaller of the two.

The user saw kit grass, ferns and flowers lit up at night. Nothing was
emissive and every layer draw binds the scene's lighting; what differed was
occlusion. At night the sky's light is nearly all the light, and it is
scaled by ambient occlusion: the meadow's blades are heavily occluded near
the ground, while a kit plant's own AO map knows nothing of the grass around
it, so it took the full sky. By day the sun hides the difference.
model.vert hands on each vertex's height above the model's base (v_lh), and
a non-blade FOLIAGE plant under 2 m scales its AO from 0.35 at the ground to
1 at 0.9 m. Crowns and the blades are untouched.
Measured in the lab (R3D_AT=tree, same binary, old and new SPIR-V): the fern
against the meadow beside it was 2.05x at 23:00 and 1.66x at 13:00; now 1.58x
and 1.60x - the same relation by night as by day. The flowers' brightest
tenth at night 78 -> 52. The noon frame moves 8.4% of pixels past 8 (the fern
and flower bases a little darker; run-to-run noise is part of that).

The user's play found the aspens' branches swinging like rope. Three terms:
- the whole-tree bend reached 22% of the tree's height at a gust's top (three
metres on a 14 m aspen); 4.5% now, and the side-to-side part at a quarter of
that and slower;
- a branch term: nothing within 0.35 m of the trunk, growing with the distance
out, phased by the direction the branch leaves the trunk (constant along a
branch, so it moves as one piece and its neighbours are out of step);
- the aspen's leaf flutter took its phase from each vertex at eleven radians a
metre, which bent every twig along its length; about three now, and half the
amplitude.
Measured on the lab's `aspen` view (10-frame bursts, crowns only, same binary
with the old and new SPIR-V): pixels moving more than 8 over ten frames 16.8%
-> 9.7%, frame to frame 4.4% -> 2.1%. SPIR-V rebuilt with `ludic-dev shaders`
(vertex stages only; the manifest is unchanged).

Every read of the screen made bytes(screen_w * screen_h * 4) and dropped it:
the user's manual play left 22,970,368 B unreachable (exactly 3024x1898x4)
at gpu_vk_draw.ludic:1673 - one per photograph (shots' ph_grab, through
gpu_read_screen_bytes). The read-back is now gvk_read_px, made once and made
again (the old one freed) only when the screen's size changes.

water_reflection_pass made view(water_saved, 16, 16) and view(water_saved, 32, 16)
inside the block that makes the reflection target, so every time the target was
made again (a resize, a render scale, a settings change) two more 16-byte views
were made and the last two dropped: the windowed walk's fence caught one such
frame, +32 B. water_saved is the state's for good, so its views are made once.

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

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.

The valley's reachability scan (R3D_ALLOC_SCAN) listed render3d start-up objects nothing held; all were

The retire, free-range and spare-id lists (4096), the per-buffer flags and the prime handles (16384),
the stage and the actor spares (2048), the per-program uniform offsets (4096) and a draw's set key

The texture and framebuffer tables grow to 4096/1024 and gvk_prime's queue is made in
gvk_startup_state; gpu_unit_2d's and the actor lists' lazy starts go. @alloc_ok on layer_room (a layer

gsl_struct/gsl_fn, an actor's part tables (given back by actor_release) and the pool's fallback.

Seventeen inline messages (allocation failures, missing conversions, the no-pipeline and compressed-
target warnings, resize and swapchain lines, the test-frame camera line, DLSS evaluate, shadow memory,
stream and terrain debug, the water test) are each a function of their own under @alloc_ok, taking
numbers, so the paths that say them hold no site. post_measure's two 1x1 exposure targets are made in
post_init and DLSS's evaluate structs in gsl_init; DLSS's camera up is a state field. The lists play
pushes into (retired, free ranges, spare ids, the per-buffer gpu flags, the stage and the actor spares)
get their room at start-up (gvk_room_*, actor_room), so a push fits. Compiled (steady).

Render3dState's cam_planes, gpu_u_tmp, q_scratch, ov_nine_buf, the caster test's four points,
ter_bw, ter_scr and water_saved default to their buffers (as ludic.anim's clip state does), so the
lazy starts in cam_planes_update, gpu_tmp, terrain_height_smooth, ter_scratch, the water pass and
gvk_startup_state go. q_euler makes its views of q_scratch once (guarded on the view now). Compiled.

shadow_pass's fbo status and probe block, shadow_bind's two location prints, layer_partition_lods'
LOD line and layer_update's dump are each a function of their own under @alloc_ok (debug switches

The renderer starts itself from the first frame (gpu_select), so the device, its tables, the
manifest and programs, grass, shadows, sky, terrain textures and the actor pool read as frame
allocations: each is @alloc_ok as start-up, with gvk_fail (a failure) and the actor census and
texture dump (debug switches). ov_nine's four corner/uv arrays are one floats(16) made in
gvk_startup_state; ac_in_light's four points are made there too. Compiled (steady, and ludic deps

actor_own_skin(a) gives an actor its own clone of its model's skeleton and actor_release frees it
(skin_clone_free: the pose, matrices, views and scratch the clone made; the rest data stays its
source's). gvk_startup_state, at the end of gvk_init, makes the scratch and tables a draw used to
make on first need (gvk_tmp_buf, the pipeline fast cache, the set key and per-program uniform
offsets pre-sized to 4096 programs, skip/seen/size words, spare and retired lists, the grass cull's
words), and those frame paths no longer start them. Compiled (steady).

@alloc_ok with its reason on what is made once per resource and kept (textures, programs, samplers,
views, layouts, memory blocks, the pipeline cache in gvk_pipe_build), on resize and swapchain
remakes, on screenshots and dumps, on a world being set up (streams, layers, water, post, bakes), on
loads (gltf_load, skin_load, tex_load*, png_decode, fonts) and on R3D_PROF / drawstats.
gltf_cached's hit path is its own and makes nothing; the miss (gltf_cached_load) is declared.
m4_look_at (now over m4_look_at_xyz) and m4_inverse work on scalars, and cam_update makes no scratch.
Left: lazy first-use starts, error and debug prints, and scratch made and freed each call (churn,

gvk_pipeline_fast's miss (the build and the six cache pushes) is its own function, so the fence can

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

A game placing props while it plays (a sign an animal leaves, a fish, a bobber) loaded each through
gltf_load, which reads the file and parses its document every time. gltf_cached finds the same

a model whose document is read after the load (ludic.anim's clips) still goes through gltf_load.

- 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
