After Effects feathers both edges of the wiped wedge (the start ray too) with
a Gaussian whose width is constant in pixels: Completion 40, Start Angle 30,
Counterclockwise, Feather 20 (AE 2026, case 904 E12) fits sigma = 0.4 x
Feather = 8.0 px at every radius (mean alpha error 0.0002 over the frame).
EffectCraft ramped only the moving edge, linearly over Feather degrees, so
the edge was 14 px wide near the centre and 140 px wide at 400 px out, and
the start edge was hard: 378 of 5184 grid points off (max 111/255, 6.6 % of
pixels > 8), now 1 (max 3), 0.009 % of pixels > 8 (near the centre). CPU and
GPU (the kernel now measures distances to the two rays). 0 % and 100 % are
unchanged, so the three Transitions presets keep their end frames; their
Feather (6 / 10) now means pixels.

After Effects measures the blinds' phase from the layer's centre and softens
both edges of the transparent band with a Gaussian of sigma = Feather / 2; the
band runs from the origin's phase to Completion x Width. EffectCraft measured
from the buffer corner and ramped only one edge linearly over Feather (a hard
edge on the other side). Fitted to AE 2026 renders of Completion 40,
Direction 30, Width 50, Feather 5 on a 960 x 540 and a 480 x 270 layer (the
origin is the centre + 0.6 px): case 715 was 499 of 5184 grid points off
(max 91/255, 7.1 % of pixels > 8), now 28 (0.056 %), all within ~6 px of the
layer edge where AE differs (up to 48/255, not modelled); away from it within
6/255 (test: one AE row of the 480 x 270 render). CPU and GPU (new erf-based
kernel, same term count). Completion 0 / 100 are unchanged, so the
Transitions presets keep their start and end frames.

After Effects' Radial Blur keeps a layer's edges: Zoom 20 on a flat grey 960x540
solid over red (case 713) stays flat and opaque to its edge, and a zoomed
full-frame ramp (case 829) keeps the frame opaque (2/255 at x = 2, 253/255 at
x = 1917 on row 540). EffectCraft sampled transparency outside the layer, so its
edges faded and the red below showed through (713: 3.9 % of the frame off, max
64/255). Now 713 is identical to AE (max 0/255), CPU and GPU. CC Radial Blur
(already matching AE) is unchanged.

With Glow Colors = Original Colors, After Effects thresholds each channel of
the straight colour separately and the glow is 8 x (value - threshold +
0.061) per channel (times Intensity), nothing below: fitted to AE 2026
renders of grey 0.65 / 0.8 / 0.9 / 1, orange (1, 0.5, 0) and (0.2, 0.6, 1)
solids at Threshold 40 / 60 / 80 % and Radius 10 / 30 (36 channel values,
exact to the 8-bit capture; an orange solid glows red only). EffectCraft
scaled the colour by a luminance threshold (k = (L - thr) / (1 - thr)), about
3.7 x too dim on white. Cases 806 / 810 / 811 (32 bpc): outside the layer
now within 3/255 of AE (806 white at Intensity 1: 119 = AE, was 32); grid
0 points off for 806-810. The glow's alpha (the blurred layer alpha) and the
Arbitrary Map / A & B colours and alpha-based glows are unchanged.
Stacked on fix-glow-halo (same lines). Not changed: Composite Original's
semantics are swapped against AE's names (EffectCraft's "On Top" adds the
glow over the original, which AE calls "Behind"; AE's "On Top" keeps the
original over the glow), so imported AE Glows at the default Behind show
no glow inside the layer (811 interior 204 vs AE 255).

With Glow Based On Color Channels, After Effects gives the glow the layer's whole
alpha (blurred), not the thresholded part, and Intensity scales only its colour:
a layer below the threshold darkens what lies under its edge. Fitted to AE 2026
renders of a grey solid over red (cases 524, 807-809): the halo is the same at
Intensity 1 and 3 and with Composite Original Behind or On Top, and its edge is
an erfc step of sigma = 0.384 x Glow Radius at radius 10 and 30 (was radius / 2).
524 (Glow defaults on a 50 % grey solid): EffectCraft had no halo (max 116/255
off at the edge); now red 248/234/208/165/140 at 7.5/5.5/3.5/1.5/0.5 px outside
vs AE 249/235/206/164/140, max 2/255 over the frame, CPU and GPU. The blur
width applies to every glow; alpha-based glows keep their coverage rule
(thresholded alpha, scaled by Intensity). Not matched yet: the brightness of glows above the
threshold (AE about 3.7 x brighter for a white solid, cases 806, 810, 811).

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.

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.
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 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.

Masks are applied before effects, but the noise was composited with the
Opacity alpha alone, so a masked solid filled the whole layer. The result
is now multiplied by the original alpha on the CPU and on both GPU paths
(kernels.wgsl for the default settings, fx_noise.wgsl for the rest).
