Review: still_at_size returned a smart object's pixels unresampled when they differed from the
footage's nominal size. It now follows footage_buf: pixels larger than nominal are resampled to
the requested size, smaller ones are left for the renderer to scale up.

The Index-units test now opens the Units popup in the Timeline and picks
Index, asserts the stored Units value, then reads the painted Start, End
and Offset, so it also fails when the Units control doesn't update the
session.
Review: frame_at_size at a still's native size made a second cache key, so the pool decoded
and kept a second full-size copy of a frame thumbnail() or frame() already had.

The playback prefetch only looked ahead*3 frames (96 with 16 workers) for uncached frames.
After a loop or a restart from the start those were all cached, so the workers stood idle until
the playhead came within that window of the end of the cached run, then the preview stalled.
A playing preview now looks as far ahead as the RAM preview holds (and the range spans) for
the next uncached frames, still queuing at most ahead at a time; eviction already spares the
frames the playhead reaches first (#595).

Footage layers had no layer cache key, so a still made a new layer buffer every frame on every
preview worker, and the GPU compositor uploaded it again each time (its upload cache is keyed
by buffer). Stills (without a proxy) are now keyed like text and shape layers, without the
source time; movies and sequences are unchanged.

The media pool honoured the requested size only for movies; stills came back
at full size and the renderer resampled them on every frame. A 21120 px wide
plate at Quarter was re-filtered each frame, and four of them (1.85 GB as f32)
did not fit the 1 GiB pool, so they were also decoded again and again.
Stills are now resampled once with effectcraft_raster::resample (the same
call the renderer made, so pixels are unchanged) and the pool keeps the
reduced copy under the sized key.
#1812 project at Quarter, CLI bench: 410 ms -> 33 ms a frame (26 ms with the
layer cache); desktop playback 2% -> 60-99% of real time.

Illustrator EPS imported as an empty layer. Three gaps in the PostScript
interpreter, each against the PostScript Language Reference:
- An operator stored under another name (`/mo /moveto load def`, as
Illustrator's prolog does for every path and paint operator) pushed the
operator's name instead of running it, so nothing was drawn.
- Device queries that return values (currentpagedevice, currentscreen,
currentflat, currenthalftone, status, dictstack, ...) pushed nothing,
shifting the stack under the procset's guards. They now push a plain
device's defaults; setscreen pops its three operands.
- `currentfile 0 (eod) /SubFileDecode filter` now skips to the end-of-data
string, so an embedded XMP packet isn't run as PostScript.
The regression test uses synthetic PostScript only.

xtask bench passed the whole layers scenario on one command line, longer
than Windows' 32 767-character limit (os error 206), so no scenario past
demo ran. effectcraft-cli run takes --args-file F (one argument per line)
and bench writes its commands there.

WGSL cannot read Rust constants, so the Rec. 601 luma (Tint, Tritone, Luma Key /
Extract), Black & White's tint weights and Exposure's 2.2 power stay literals in the
kernels; they now name their Rust source (effects::LUMA_601, BW_TINT_LUMA,
EXPOSURE_LINEAR_GAMMA, newly exported) and the test shader_constants_match_the_cpu
(no GPU needed) fails if a literal drifts. gpu_tint_defaults_match_after_effects_greys
says "skipped: no GPU adapter" when it skips (EFFECTCRAFT_REQUIRE_GPU=1 still makes it
fail). docs/effects-parity.md: Brightness & Contrast is close to, not the same as,
After Effects (up to 6.2/255), and the summary row lists what is measured.

After Effects' Curves effect interpolates its points with a natural cubic
spline (zero curvature at the ends), clamped to 0..1: AE 2026 renders of an
RGB curve (0,0) (125,199) (255,255) and a Red curve (0,0) (128,44)
(255,255) (cases 962 / 963, ROUND4) give exactly the natural spline's values
on every grey step (0, 30, 59, 115, 164, 202, 227, 242, 250, 255 and 0, 0, 1,
6, 19, 44, 83, 135, 194, 255). EffectCraft used a monotone (Fritsch-Carlson)
spline: 34 / 67 / 125 / 171 ... on the RGB curve, up to 10/255 off (ROUND4
measured up to 6 levels on real projects); now within 1/255, CPU and GPU (the
same Hermite tables carry the spline's knot slopes). Lumetri's curves and
Glow's Arbitrary Map keep the monotone spline (not measured).

Without a Fill Mask, After Effects turns the layer into the fill colour and
applies Opacity to its alpha; nothing of the original shows through. AE 2026
renders Fill (0, 0.5, 1) at Opacity 50 % on a Gradient Ramp over a red solid
as premultiplied (0, 0.251, 0.502) at alpha 0.502 at every pixel; EffectCraft
mixed the fill with the ramp (mean difference 95.5/255), now within 1/255,
CPU and GPU. Invert fills the transparent part the same way. With a Fill
Mask the mix with the original is unchanged (not measured). Lottie's fill
effect (colour, alpha x opacity) now plays the same in EffectCraft.

After Effects weighs each of the four points by its inverse squared
distance softened by Blend squared, 1 / (d^2 + Blend^2) in pixels: fitted to
AE 2026 renders of the default gradient at Blend 10, 100 and 300 and case
904 E16 at Blend 50 (power 2.00 at every Blend, softening 0 / 2367 / 9817 /
90127 = about Blend^2; mean error 0.27/255, max 0.9). EffectCraft used
1 / (d^2 / (100 Blend))^1.5, in which Blend cancels out: E16 was 34/255 off
on 99 % of the grid, now 0 grid points off, max 1/255, CPU and GPU.

After Effects 2026 keys Luma Key and Extract (Channel Luminance) on Rec. 601
weights of the working-space values: Key Out Darker / Extract Black Point at
65, 166 and 24 on pure red, green and blue keep red (601: 76, 709: 54) and
blue (29 / 18) and key out green (150 / 182) - Rec. 709, which EffectCraft
used, decides all three the other way. Case 904 E18 (Extract 30 / 220 /
softness 10 on grey and colour steps): 513 of 5184 grid points off (pure blue
kept at 231 in AE, keyed out in EC), now 0, max 0. CPU and GPU.

After Effects' Luma Key removes everything darker (or brighter) than Threshold
and ignores Tolerance for those two key types; Tolerance only sets the band of
Key Out Similar / Dissimilar. EffectCraft ramped the matte over Tolerance, so
case 719 (a 50 % grey, Key Out Darker, Threshold 140, Tolerance 20) kept about
80 % of the layer where AE keys it out completely.
Measured in AE 2026 on a vertical grey ramp (cases 812-814): Darker keys up to
level 139.9 and keeps 140.1 (EffectCraft now the same row); Similar keys levels
120.3-160.0; with Edge Thin 1 / Edge Feather 2.5 the matte rises over rows
591-596 (EffectCraft within 0.2 of AE's alpha there). CPU and GPU.

In After Effects 2026 the non-legacy curve of Brightness -40 is the inverse
of Brightness +40 (within 2.6/255 on a full black-to-white ramp) and Contrast
-50 the inverse of Contrast +50. EffectCraft fitted the negative brightness
with its own power (2^(1.32 |b|) on v), 20/255 off AE at -40; the negatives
now use the reciprocal exponents of the positive curves: Brightness -40 max
6.2/255 (was 19.8), Contrast -50 4.1 (was 7.0); positives unchanged (40:
5.5, 80: 7.8, Contrast 50: 2.7, 90: 5.0; B20 C30: 6.6, which confirms
brightness before contrast). The #681 oracle samples still pass. CPU and GPU.
The positive curves' remaining 5-8/255 needs a better curve family (a
two-point spline fits each capture within 1.6/255), left open.

After Effects 2026 in a 32 bpc project, Levels (Individual Controls) with RGB
(0.1, 0.9, gamma 1.5, 0.05, 0.95), Red Gamma 0.8, Green Input White 0.8 and
Blue Output Black 0.2 on grey steps 0..255 (case 904 E07): every step matches
"each channel's controls, then the RGB controls" with nothing clipped
(values below Input Black end below Output Black, above Input White above
Output White). EffectCraft ran RGB first and clipped "Off for 32 bpc Color"
(it could not see the bit depth): up to 27/255 off on 95 % of the grid; now
0 grid points off, max 1/255, CPU and GPU.
EffectEnv gains float_depth (the renderer sets it for 32 bpc projects), so
"Off for 32 bpc Color" clips in 8 / 16 bpc projects as before. Unclipped
values below 0 take the gamma mirrored through 0. Plain Levels keeps its
order (its channel controls were not measured); its clipping follows the same
rule. EffectCraft's own projects default to 8 bpc and are unchanged.

All twelve sliders (Master, Red, Green, Blue) take After Effects'
ranges: Exposure valid -100..100, slider -4..4, 2 decimals (was -20..20,
slider -5..5); Offset -2..2, slider -0.5..0.5, 4 decimals (unchanged);
Gamma Correction valid and slider 0.1..10, 2 decimals (was 0.01..9.99,
slider 0.1..3).
Every value inside the old Exposure and Offset ranges stays valid. Saved
values are not clamped on load, so a gamma below 0.1 from an older
project or a Photoshop import (0.01..9.99) is kept and still renders
(the renderer's 0.01 floor is unchanged); only new edits clamp to 0.1.
Test of the ranges and of an old gamma surviving the load refresh.

With Bypass Linear Light Conversion off, Exposure decoded and re-encoded
with the piecewise sRGB curve. After Effects 2026 renders (sRGB working
space, 32 bpc) of Offset 0.0005 / 0.002 / 0.02 / 0.1 on black measure
8 / 15 / 43 / 90, which a pure 2.2 power predicts (8.06 / 15.13 / 43.08 /
89.54) and the sRGB curve does not (1.65 / 6.59 / 38.68 / 89.04).
The effect now uses its own 2.2 power curve on the CPU and in the GPU
kernel; the shared colour functions and other effects are unchanged. As
before, the conversion applies whatever the working space, also a
linearised one. Negative values go through both curves mirrored (input
was clamped at 0 before), so defaults are an identity for 32-bpc values
and a negative Offset darkens past black without NaN.
New test against the AE values; existing Exposure tests still hold.

After Effects tints Black & White's gray like a Color blend: the tint colour's
hue and saturation at the gray's luminosity (weights 0.3 / 0.59 / 0.11, channels
outside 0..1 pulled back toward the gray). EffectCraft used the gray as HSL
lightness. Measured in AE 2026, Tint Color [1, 0.5, 0]: a red solid at Reds 10
(case 717) AE (43, 21, 0), EffectCraft was (51, 26, 0), now (43, 21, 0); a
yellow solid at the default sliders (gray 0.6, case 825) AE (255, 129, 2), now
(255, 129, 3); white stays white. The six sliders already matched AE on eight
colours (cases 816, 817). CPU and GPU.

After Effects' Tritone weighs the working-space values with Rec. 601 (0.299,
0.587, 0.114), as its Tint does; EffectCraft used Rec. 709. Case 718 (red solid,
Highlights [1,1,0.8], Midtones [0.6,0.2,0.2], Shadows [0,0,0.3], Blend 25):
AE (132, 23, 46), EffectCraft was (113, 16, 49), now (132, 23, 46). On a grey
ramp (case 815) the shadows / midtones / highlights mapping already matched and
still does within 1/255. CPU and GPU (fx_color op 4).

Start, End and Offset are read as painted in the Timeline: with % under
Units = Percentage, without it under Units = Index. Fails on the old
suffix rule ("0.0%").
With Units set to Index the selector already counts characters (words,
lines), but the timeline kept showing Start, End and Offset as
percentages ("3.0%"), so switching looked like it did nothing. They are
now shown without the % sign while Units is Index
(render::text::in_index_units).
layer.setSwitch with no value toggles relative to the first selected layer in
composition order, so with a mixed selection (A checked, C unchecked) clicking
C's box could leave C unchanged. The checkbox now sends the value it toggles
to, as the switches do.
The Timeline draws the Video switch (the eye) on every layer's row, nulls,
cameras and lights included, but set_switch_others and hide_other_video
skipped cameras and lights: Alt-clicking the eye of a selected layer neither
set them apart with the selection nor hid them with the rest.
Both now use the rule the eye cell shows: every layer but track mattes.
The label swatch's menu, the Blending Mode menu and Preserve Transparency
passed the clicked layer alone, so a colour or a mode had to be set one layer
at a time. They now act on the whole selection, with the Modes column edits
going only to the selected layers that have video, as its cells do.
The preserve-transparency checkbox also gets an automation id, like the cells
around it.
A switch click on one of several selected layers passed that layer alone to
`layer.setSwitch`, so Lock, 3D, Video (and the rest of the A/V Features and
Switches columns) had to be set one layer at a time.
The click now gives the switch to the whole selection, with the layers it
doesn't apply to left out (3D on a camera, Effect on a layer without effects,
Audio on a layer without audio, ...). The targets are picked when the press
happens, so drawing a row costs nothing more than before. A row that isn't
selected still changes that layer alone, pressing and dragging over rows is
unchanged, and Alt-clicking an A/V feature sets the selected layers apart.
At preview scales from 0.75 to 1 footage keeps native pixels, a proxy sets
its own buffer scale at any render scale, a Preserve Resolution precomp is
drawn at full size, and earlier effects can pad or offset the buffer, so
snapping to the preview grid could pick a different ID than the rendered
matte. Use the scale and offset of the buffer the Cryptomatte effect
receives (layer_input, rendered once and then cached).
The pixel centre goes to an aux point through effectcraft_effects::aux_point,
which index_map_at now calls too, so the two round identically (a division
vs the reciprocal picked the other ID on a 104 px proxy of 1920 px footage).
An unknown effect uid errors "no such effect" and a layer without pixels
"this layer has no pixels", as effect.pickColor does.
Engine part of viewer picking: replace / add / remove the top-coverage ID at a
layer-space point in one undo step, at the time the Selection was read. The
aux channels come from the render's own path (Renderer::layer_aux, shared with
the effect host; footage at its source time, 3D precomps) through a renderer
set up like Session::render (expressions, render prefs, layer cache). An
optional scale snaps the point to the pixel a preview at that resolution
samples. New effects::crypto_select quotes names and falls back to <hex> for
unnamed, wildcard-looking or ambiguous names. effect.cryptomatteAt is the
read-only hover query.
