Evaluate the third cube coordinate symmetrically to retain the intended centerline tie. Keep the existing pixel oracle and tolerance.
Scope the Mem fixture mutex unwrap allowance so the original strict CI can validate this base.

The Advanced 3D renderer folded Accepts Shadows (Off/On/Only) into a
bool, so a shadow catcher set to Only drew as an ordinary lit surface.
The material now carries shadows_only. Such a fragment draws black at
the strongest shadow a light casts on it, as Classic 3D does, and it
goes in the blended pass so what is behind it shows through. The CPU
shader and advanced3d.wgsl get the same branch.

crypto_aux_image_with takes CryptoAux::{ColorsAndMatte, MatteOnly}, and
CryptoAux::for_display holds the rule for which displays read the ID
colours. A new GPU test checks every display x Matte Only against the CPU,
so the GPU fails the test if the shader starts reading RGB in a mode that
skips it (checked by mutation: forcing MatteOnly fails display 0).
GpuContext::request() now applies InstanceDescriptor::with_env() (WGPU_BACKEND,
WGPU_DX12_COMPILER, WGPU_VALIDATION, WGPU_DEBUG, ...), the same variables the
desktop app honours via egui-wgpu, and requests PowerPreference::from_env(),
defaulting to HighPerformance (an unknown WGPU_POWER_PREF logs a warning).
WGPU_ADAPTER_NAME (CLI/headless only; the desktop ignores it) picks the first
adapter whose name contains the trimmed value, case-insensitively. Empty or
blank counts as unset. Only the name is matched (backend via WGPU_BACKEND). A non-matching name is an
error that says so and lists each distinct adapter once as 'name (backend)', instead of wgpu::util::initialize_adapter_from_env's panic;
no adapters at all gets its own message.
Output is bit-identical (all displays, CPU and GPU). At 2560x1440 with 3 ranks and 2000 IDs on 8 cores the CPU effect drops from ~87-135 ms to ~44-54 ms and the GPU path's aux reduction from 38 to 8 ms for Matte, Preview and Matte Only.
Entries whose layer buffer was freed were pruned only once the cache went over its budget
(1.5 GiB), so an animated layer, which makes a new buffer every frame, left a dead 4K texture
per frame allocated until the cache filled up.
Black & White offset each pixel's luminance by (hue weight - 0.5) times
its HSL saturation. HSL saturation is near 1 for any tinted near-black
pixel, so the code or two of colour noise in compressed footage's
shadows came out as bright and black blocks, and a 32-bpc overbright
such as (1.5, 0.5, 0.5) divided by zero and went black.
The gray is now the pixel's smallest channel plus its chroma (largest -
smallest channel) times the same hue-interpolated slider weight. Neutral
pixels keep their value, a pure hue becomes its slider's percentage
(Reds 40% turns pure red into 40% gray), noise moves the gray by no
more than its own size, and nothing divides. The CPU effect and the GPU
kernel change the same way.
The keyed Birth Rate comparison is shared (keyed_agree) and now runs on
CC Particle Systems II too. The same two histories bear 90 particles by
0.9 s at different steps: the GPU's particles match the CPU's, and each
state really came from the GPU.
The two histories now bear the same 180 particles by 0.9 s at different
steps (3/s from 0 to 0.5 s, and from 0.25 to 0.75 s). So a checkpoint
check by birth count alone fails the test, not only no check. A
test-only dispatch counter asserts each GPU state really came from the
GPU rather than the CPU fallback.
With a Birth Rate keyed into a burst, the GPU's particles match the CPU
simulation through the burst and after it. A second history with the
same system key, whose burst starts later (so the same ids are born at
other steps), isn't resumed from the first history's GPU checkpoints.
The simulation runs from layer time 0, but it used the Birth Rate of the
rendered frame for every step. A rate keyed from 3 down to 0 simulated
no births at all once it reached 0, so the burst's particles vanished
that frame although their Longevity had not run out. A ramped rate was
simulated as if its current value had always applied.
Each step now samples Birth Rate at its own layer time through
EffectHost::param_at (with the effect's own index). Without such a host
the current value applies throughout, as before. Particles already alive
keep moving and ageing whatever the rate. The carry and particle ids
continue across rate changes.
Birth Rate is left out of the simulation cache key, so an animated rate
no longer restarts the simulation every frame. In its place:
- The CPU state keeps a hash of the rates it was stepped with (hist). A
checkpoint is resumed only when that matches the current history, so
moving an earlier key is never served from a stale checkpoint.
- The GPU gets the birth schedule of the sampled rates (births_at). Its
checkpoints record which births they hold, and are resumed only when
the request's births before that step are the same.
A constant Birth Rate gives exactly the particles it did. CC Particle
Systems II and CC Mr. Mercury keep their constant-rate simulation.
Since #659 every text or shape layer with an enabled video effect grew its
effect buffer to the comp-sized layer rectangle before the stack ran, so
glow and blur — which only need their own margins — allocated a 1920x1080
RGBA32F texture per layer per frame in flight (~5 GB peak VRAM in parallel
export, measured on an RTX 3090).
Effects that actually place pixels outside the painted content already
grow the buffer themselves by exactly what they need (CC Tiler, CC Smear,
CC Mosaic sharp via layer_cover_pad / Buf::pad), on CPU and GPU. The
blanket target.cover(layer_size) in Renderer::run_effects_on, the
FxTarget::cover trait method with its CPU default, and the GPU
GpuTarget::cover texture allocation are removed; Buf::cover/cover_plan
stay as the effects-crate helpers they were designed as.
The #659 regression tests (tiling across the layer region, centred-shape
edge pinning) and the render/effects/gpu suites pass unchanged.
The pinning regression only exercised All Edges (and Left Edge in the CPU
unit test), so the reported 'does not work with Top/Bottom Edge' had no
coverage to catch or clear it. This holds the pinned first/last row in a
CPU test at Direction 90, and adds CPU/GPU parity cases for Top (4),
Bottom (6), diagonal directions, and single-edge pinning on shape layers.
CPU pinning verified correct on main: the guards in dst_wave_pin/wave_pin
agree; the gap was that neither edge path was tested.
The Gradient Ramp wrote alpha 1.0 to every pixel, so a shape layer's transparent area filled up with
the ramp and the layer's bounds showed instead of the shape. The ramp now uses the pixel's own alpha
on the CPU and in the GPU kernel, as the #939 fix does for the noise effects. A regression test
checks that transparent pixels stay transparent at two Blend With Original values.

AuxChannels::crypto_rank_planes resolves a layer's (ID, coverage) planes once; crypto_ranks keeps its signature on top of it. The CPU effect and the GPU effect's aux image (effectcraft_effects::crypto_aux_image, rayon) index the planes per pixel. Output is bit-identical.
- GPU Pixel Motion Blur (#695) declined without a host; it now averages the shutter's
frames like the CPU effect (tests_fx_time::without_a_host).
- add_item_keeps_footage_longer_than_the_comp_at_full_length (#798) built footage with
the default kind (Still), which adds at comp length; it is a movie.
- docs/effects.md regenerated.
