The 2^28 pixel limit applied per image; one composite or layer decode kept
the ZIP output, a Vec<f32> per channel and the result alive together, and the
bake size came from the file's quad. A decode now charges every buffer
against a byte budget (4 GiB, 1 GiB on 32-bit), checks its whole expected peak
before allocating, writes channels straight into the result and returns an
error when over budget. Bakes are at most 4x the document across and 2^24
pixels.

Raw channels are borrowed, ZIP planes are un-predicted in place in the inflated buffer,
the 32-bit un-predictor uses one scratch row, the layer mask tests the rect per row
instead of per pixel (and skips a constant factor of 1.0), and a placed-layer bake
solves the quad once and hoists per-triangle invariants. Output is bit-identical;
tests compare against the replaced implementations and count the avoided work.

Psd::parse drops the layers, records Psd::warnings and keeps the header and
merged image; the importer then imports the flattened image as one layer and
reports 'Layers could not be read'. Header damage and a missing merged image
stay hard errors.

One decode_plane for raw/RLE/ZIP (decode_channel and composite), placed::eight and
quad_from for the SoLd/PlLd transforms, the writer's big-endian and UTF-16 helpers
from descriptor.rs, one delimiter const in engine_data.rs, and the dead binding in
write.rs. No behaviour change; adds ZIP and RLE composite tests.

Psd::tree flattens groups nested deeper than MAX_GROUP_DEPTH into their depth-64 parent, keeping every layer, so the importer recursion and the tree's Drop/Clone/PartialEq are bounded. The import result reports how many groups were flattened.

Problem: the built-in animation preset library had no Backgrounds category
(gap 7: 31 presets against After Effects' 621).
Fix: 23 original Backgrounds presets in crates/engine/presets/backgrounds.json,
built from our own generator, noise, colour and stylize effects: Soft Gradient
Drift, Aurora Veil, Slow Fog, Cloud Bank, Dark Smoke, Ember Haze, Magma Flow,
Ice Flow, Pastel Plasma, Cell Drift, Crystal Facets, Hex Mosaic, Mirrored Silk,
Water Caustics, Blueprint Grid, Checker Scroll, Scrolling Stripes, Pulse Rings,
Bokeh Drift, Spotlight Floor, Dawn Sky, Sweeping Light, Grainy Wash.
The preset format gains `expr` (an expression per property, so backgrounds keep
moving for the whole layer) and point parameters written as fractions of the
layer size. Effects & Presets lists them under * Animation Presets > Backgrounds.
Tests: catalogue uniqueness and categories, apply/undo/redo of every preset
(engine), render of every preset with the expression engine: finite,
non-flat, deterministic, moving (host), panel listing and apply (ui-egui).
Sidecar, ATTRIBUTION.md, gaps.md row 7 and effects-parity.md updated.

Guides can store a percent of the comp so they follow comp-size changes
(View > Add Percentage Guide, Convert Guides to Percentage / Pixels); an
effect instance has an optional colour label (effect.setLabel, Effect Controls
header bar and Label menu). Both are serde-defaulted, so old projects load.

A vertex under or beside a box handle lost the press to the handle (the handle reaches 9 points, the vertex 6), the resize cursor showed over it, and the handles were painted over the vertex markers. Vertex reach now matches the handle's wherever one is in range, the cursor stays a pointer, and markers are drawn last.

The media layer keys decoded frames by path, and nothing dropped them when a
new project (or a new import) named a file that another app had overwritten
since, so a same-size overwrite showed the old pixels. Importing footage and
replacing the project now make the media layer and the layer cache let go of
the files involved.

fanning_out_reads_stop_at_a_budget expects the run-count error, but under heavy load
the 5 s wall-clock budget could fire first (different error). Add a test-only
per-thread time limit and lift it in that test. Wall-clock assertions in the other
new tests are now only generous hang guards (>=10x), the fuzzer's hang deadline is
24x MAX_TIME and the perf bound is 10x looser.

Problem: footage audio kept only its first two channels, so the centre, LFE and surrounds of a 5.1 file were dropped. AAC 5.1 was worse: FilmCraft's AAC-LC decoder delivers AAC's own order (C L R Ls Rs LFE), so the left output was the centre and front-right was lost.
Fix: crates/media/src/downmix.rs holds one ITU-R BS.775 stereo downmix (centre and surrounds at -3 dB, LFE left out, fixed normalisation by the largest row sum so full scale cannot clip), with channel orders for 3 to 8 channels in WAVE/SMPTE order and AAC's native order, and only the front pair for more than 8. MediaPool::read_stereo applies it, which preview, waveform and export mixdown all read through. Mono and stereo are unchanged.

Problem: the extra panes of View > Switch View Layout were fixed to Top, Front and Right, and the 3D View menu only changed the main view.
Fix: every extra pane has a view selector (Active Camera, Default, Front, Left, Top, Back, Right, Bottom, Custom View 1-3). The choice is kept per comp in Views3D::panes (serde default, so older editor states load with Top/Front/Right) and set by the new command view.setPaneView {pane 0-3, view}. The Active Camera pane renders through the comp camera.

Problem: the Timeline shows non-drop timecode, but time.set (the current-time field) parsed
typed text as drop-frame at 29.97/59.94 fps, so committing the displayed time, or typing a
time, landed on another frame from minute 1 on (frame 1800 "0:01:00:00" -> 1798).
Fix: typed text is read as drop-frame only when it uses ';' fields; ':' and '.' follow the
displayed non-drop style. Regression test round-trips the display at both rates.

Problem: the viewer blurred hard edges even at Full resolution and 100 %
(reported on Discord). The frame rect was centred without snapping to
physical pixels, so bilinear sampling blended neighbouring pixels at 1:1
(worst at 125 %/150 % display scaling); More Accurate also magnified
bilinearly, so 200 %+ and lower resolutions were smoothed; and Zoom In /
Zoom Out stepped in points, so at 125 % scaling they never reached 100 %.
Fix: snap the frame origin (and the ViewerMap overlays use) to the
physical pixel grid; magnify with nearest in both Zoom Quality modes
(CPU texture options and the GPU frame sampler), keeping the averaged
minification below 100 % (#417); the snapshot texture follows the same
options; Zoom In / Out step through screen-pixel magnifications.

Problem: a movie whose profile the software decoders lack (H.264 High 4:2:2 / 10-bit)
probes fine, then every frame read fails; MediaPool logged the error per frame and returned
None, so the layer rendered black with no sign why in the viewer, Project panel or for agents.
Fix: MediaPool records the reason once per file (codec from the probe plus the decoder's text
without error wrappers; I/O errors stay with missing-footage handling), logs it once, and
exposes it through the new FootageSource::problem. The Composition viewer shows it on the
affected layer, the Project panel marks the item with a warning whose tooltip is the reason,
and project.summary / footage.info carry a "problem" field. Cleared when the file is
forgotten; only set when decoding really failed, so a hardware decoder that handles the file
shows nothing.

Problem: with several layers selected, right-clicking one of them in the
Timeline (name row or layer bar) and choosing Pre-compose, Delete,
Duplicate, ... re-selected and acted on only the right-clicked layer.
Right-clicking an unselected layer did not select it. In the Project
panel, Move to Project Root moved only the right-clicked item.
Fix: as in After Effects, a right-click on a selected layer keeps the
selection and the menu's commands target every selected layer (in comp
order); a right-click on an unselected layer selects only it. Move to
Project Root uses the same selection targets as Delete and Label.

Problem: Tab in a Project panel rename (or comment) field committed the
edit and egui moved keyboard focus to the next widget, the row's label
swatch. While it held focus, Enter no longer renamed (it "clicked" the
swatch), the arrow keys moved between widgets and app shortcuts paused.
Fix: the field keeps Tab through its event filter (arrows as before);
Tab surrenders focus and commits like Enter, so nothing else takes the
keyboard and the next Enter renames again.

Problem: spatial keys with huge coordinates (the Position field accepts any
finite number) overflow the motion path's arc length to NaN. SpatialSeg::at_length
only returned early for len <= 0.0, so NaN reached s.clamp(0.0, len), which
panics. The viewer's motion-path overlay evaluates on the UI thread, so moving
the current time over such keys crashed the app.
Fix: at_length returns the segment start unless the length is positive and
finite. A seeded fuzz of evaluate/velocity/spatial tangents with NaN, infinite
and +-1.7e308 values (200k tracks) found no other panic or hang.

Problem: in a 2- or 4-view layout the Top / Front / Right views drew no
camera or light wireframes, so moving a camera showed nothing there
(reported on Discord).
Fix: draw_rigs takes the view camera explicitly and a pane name for its
automation ids; aux_views draws the wireframes of each extra view through
that view's camera, clipped to the pane, with ids
viewer.view.<view>.camera.<id> / .light.<id>.

Problem: on Linux the font list only scanned /usr/share/fonts,
/usr/local/share/fonts, ~/.local/share/fonts and ~/.fonts. The ArtCraft
Launcher installs EffectCraft as a Flatpak, where those folders hold only
the runtime's fonts and the host's fonts live under /run/host, so installed
fonts were missing (25 families instead of 320 on the reporter's setup).
$XDG_DATA_HOME/fonts, $XDG_DATA_DIRS/*/fonts and fontconfig <dir> entries
were never scanned either.
Fix: a new font_dirs module lists the usual folders, the Flatpak host
folders (/run/host/fonts, local-fonts, user-fonts), the XDG data folders
and the <dir>/<remap-dir> entries of the fontconfig configuration
(FONTCONFIG_FILE or /etc/fonts/fonts.conf, /usr/local/etc/fonts/fonts.conf,
and ~/.config/fontconfig), following <include>s with prefix="xdg",
"relative" and ~ expansion. It uses a small tag scanner (no new dependency),
bounds the include depth, the number and size of files read, and reads each
file once. Folders are deduplicated before the walk, and the walk depth
goes from 4 to 8. docs/agents.md lists the folders and how to grant the
Flatpak an extra one.

Picking Alpha / Alpha Inverted / Luma / Luma Inverted in a layer's Timeline
Track Matte menu only dispatched a command when the layer already had a
matte layer, so with "No Track Matte" the click closed the menu and did
nothing. The mode items now run layer.trackMatte (Layer > Track Matte),
which keeps an existing matte and otherwise takes the layer above, or
reports that the top layer has none. The menu ticks the current mode and
the cell's tooltip names the matte layer and the mode (the 104 px cell
has no room for both).

Problem: Layer > New > Text (menu, Ctrl+Alt+Shift+T, Timeline context menus)
created a layer with the placeholder "Text" and no edit session, so typed keys
ran shortcuts; users then renamed the layer (Enter) and the name, not the
Source Text, got their text.
Fix: as in After Effects, the UI dispatch runs layer.newText with an empty
text and an edit session (insertion point in the comp centre); the name
follows the typed text. engine.execute keeps the headless default.

Problem: expression text is input we don't control, and nothing fuzzed the
expression parser and evaluator. A seeded mutation fuzzer found stack
overflows (a few hundred `?:`/`=>`/`if`, a few thousand `.`/`<`/`()` links,
75 nested template substitutions or regex groups, a chain inside one
template), hangs (an expression reading its own layer's transform nested
2^16 times; fanning-out reads; 10M-iteration loops re-run per read; loops
calling looping functions), an i64 overflow panic in wiggle noise, and NaN
path vertices tripping the rasterizer's clipping assertion.
Fix: a dependency-free seeded fuzzer (crates/expr/src/tests/fuzz.rs: real
AE-style seeds, char/token mutations, worker thread with a 2 MiB stack,
catch_unwind, deadline, env vars for long runs); a weighted nesting
estimate covering chains without brackets and template/regex insides;
cycle detection per (property, time, text); a per-evaluation budget of
20 000 script runs and 5 s (runs are interrupted through boa's budgeted
evaluation; native only); loop limit 1M; wrapping noise lattice indices;
non-finite path results rejected. Each fix has a regression test.

Problem: Object Matte had no After Effects comparison, and none can be made
on this Linux machine (no After Effects). The gap notes still listed the
viewer tool, background job and disk cache as missing.
Fix: docs/fidelity/object-matte.md states plainly that nothing is measured
yet and pins down the comparison for when an After Effects 26.2+ reference
is available: four original or openly licensed clips (the synthetic moving
disk from the engine tests, the disk with a jump, two objects with a box
prompt, one CC0/CC BY real clip), the prompt and settings, where reference
mattes stay (gitignored), and the metrics: per-frame IoU against After
Effects (headline), IoU against ground truth, boundary distance, soft-edge
error, temporal stability, drift and time per frame, plus a proposed pass
bar left to the maintainers. Linked from docs/fidelity/README.md.
docs/gaps.md (#14) and docs/target-app-parity.md now list what landed and
leave the comparison as the one remaining item.

Problem: computed Object Matte segmentations lived only in the in-memory
cache, so every restart or memory eviction segmented the shot again (After
Effects 26.5 keeps Object Matte results in its disk cache).
Fix: the persistent disk cache gets a third entry kind, Matte (folder
`mattes`, LZ4-compressed FrameSeg bytes, same checksum, atomic writes, LRU
eviction under the one size limit, purged with the rest). Entries are keyed by
the segmentation's chain key and scale; chain keys already hash the Input Key
(the layer's source, timing, masks and effects above), the prompt, the mode and
the model, so any change simply misses. The effects crate gets a SegStore
trait behind its memory cache: Chain::ensure reads from it on a memory miss
and writes what it computes. The engine installs the session's DiskCache as
the store (held weakly, so switching the disk cache off drops it). Roto Brush
segmentations go through the same chain and are persisted too. Frozen mattes
already persist in the project (the Frozen parameter).
Tests: engine tests_roto::object_matte_mattes_persist_in_the_disk_cache (a
second session on the same folder and project gets all tracked frames back
without being able to read a single input frame, renders identically, and a
moved prompt finds nothing); render disk_cache
segmentations_round_trip_and_reopen (round trip, reopen, damaged file is a
miss, size limit evicts).

Problem: Object Matte computed its frames only on demand while rendering, so
playing a shot stalled on every untracked frame, there was no progress or way
to stop, and nothing kept the mattes once computed.
Fix: Object Matte runs through Roto Brush's job machinery (one job slot,
cancellable with roto.cancel, a worker thread on the desktop, a Web Worker in
the browser, never the UI thread). objectMatte.propagate computes the frames
around the reference frame (clipped to the layer) outward, filling the same
content-keyed segmentation cache the renderer reads; the engine's sync now
queues an instance for background tracking when its frames or prompt change.
objectMatte.freeze stores the final mattes in a new hidden Frozen parameter
(Roto Brush's FrozenCache format) under a key of the input, prompt, span,
model and matte settings; renders use them without segmenting while the key
matches; a frozen prompt is refused until objectMatte.unfreeze. Freeze is one
undo step and is dropped if the prompt changed meanwhile.
objectMatte.status reports progress, frozen state and computed frames. Effect
Controls shows Freeze / Unfreeze and Track / Stop with a status line (progress
banner). The frontend now polls Roto Brush / Object Matte jobs on their own:
before, a finished job (and so a Freeze result) was only picked up while a
Warp Stabilizer job was active. Job progress is set before the worker starts.
Tests: engine tests_roto::object_matte_background_job_cancel_and_freeze
(queued by the edit, returns at once with progress, cancel keeps a partial
result, completion computes all 25 frames, frozen renders recompute nothing,
unfreeze recomputes, undo restores); effects object_matte job_frames and
frozen-matte tests (stored pattern used, key mismatch and damaged data
ignored); ui-egui ui_object_matte Effect Controls Freeze end to end.

Problem: Object Matte could only be applied through the objectMatte.apply
command; After Effects 26.2 picks the object directly in the viewer (click it,
or drag a box around it).
Fix: an Object Matte tool (with Roto Brush & Refine Edge in the Alt+W slot,
icon drawn in code). In the Composition viewer a click sets a point prompt and
a drag a box prompt (its centre the point) on the footage, solid or comp layer
under the pointer, converted to layer pixels through the layer's transform.
The layer's Object Matte (the selected one, else its last) is re-prompted;
Shift adds another. Everything goes through objectMatte.apply, which gained
`effect` to re-prompt an instance (point, box or no box, reference frame; the
reach kept unless given), so each prompt is one undo step; the effect is then
selected, so its point controls show in the viewer. Hover draws a crosshair
and the outline of the layer that would get the matte (a live matte preview
would need a segmentation per pointer move). Automation ids:
viewer.objectMatte.crosshair / .target / .box, tools.ObjectMatte.
Tests: ui-egui ui_object_matte (hover, click, drag box re-prompts the same
effect, Shift-click adds one, undo steps); engine
tests_roto::object_matte_reprompt_updates_the_instance. Checked with the
headless snapshot example (hover crosshair, box drag isolating a disk).

Problem: probe() and MediaPool's movie sources called std::fs::read and then
filmcraft_codecs::open_bytes, so a clip cost its full size in memory, twice
while probing (a 245 MiB MP4 peaked at 494 MiB just to import).
Fix: container footage on disk is opened through a positional-read
ByteReader (stream::FileReader) and FilmCraft's reader openers
(filmcraft_media::reader::open_reader; MP4/MOV, Matroska/WebM, MXF, Ogg,
MPEG-PS/TS), which read the index and then single samples. Probing takes this
path only when nothing probed before containers (still/model extensions,
PSD/SVG/PDF, image magic) claims the file; everything else, whole-file audio
formats, in-memory files (add_bytes) and wasm32 builds keep the byte path.
Regression test: probing and decoding a frame and audio of a movie with a
256 MiB tail grows peak RSS by <64 MiB (512 MiB before), same results.

Problem: with a trained model installed, Object Matte's optional box reached
MobileSAM only as background points along the box's edges (an approximation),
although the model's prompt encoder takes a box prompt directly.
Fix: a new Roto Brush stroke kind, Box (two opposite corners), that
stroke_prompt turns into the model prompt's bbox (scaled to the matte grid,
corners in any order, degenerate or non-finite boxes ignored). The graph cut
never rasterizes it. Object Matte emits it instead of the edge strokes when a
model segments; the classical fallback keeps the edge strokes. A prior matte's
box no longer replaces a box the user drew on that frame.
Tests: effects object_matte::the_box_reaches_the_model_as_a_box_prompt (a
stand-in model sees the box, at full and half resolution, and no edge points);
track roto::tests::box_stroke_is_the_model_box_prompt.

Problem: while a preview played, the RAM preview cache evicted the least
recently used frame. The frames just ahead of the playhead had been rendered
(prefetched) before the frames just shown, so once the cache was full they
were evicted first; prefetch asked for them again, but its queue ran in
request order, so they waited behind every frame further ahead. Playback
ran into a gap right ahead of the playhead while frames far ahead stayed
green, re-rendered the same frames over and over (about four renders per
frame shown when the preview was longer than the cache) and stalled for
seconds. The prefetch window could also reach further ahead than the cache
holds.
Fix: the playing preview tells Frames where it is (Frames::set_playhead).
Evictions then take frames the preview does not reach first (other series,
behind it without looping), least recently used first, then the frame it
reaches last; prefetch renders the frame it reaches first; queued prefetch
frames it no longer reaches are dropped (and leave the in-flight set). The
prefetch window stops at what the cache holds. The viewer puts a CPU frame
that needs no averaging on screen without copying its pixels.

Problem: After Effects 26.2's Object Matte (pick an object with a click,
optionally a box, get a matte that follows it) had no counterpart; only
stroke-driven Roto Brush existed.
Fix: an Object Matte effect (Effect > Matte, ec.matte.objectmatte) turns
the Object Point (and optional box) on a Reference Frame into Roto Brush
strokes and segments them with Roto Brush's engine, content-keyed cache
and the model chosen in Settings > Roto Brush (MobileSAM, classical graph
cut without it). Track Object carries the matte frame by frame up to 600
frames each way; otherwise every frame is segmented on its own. Feather,
Contrast, Shift Edge, Invert and a Matte view. The engine keeps its Input
Key current so upstream edits recompute it. objectMatte.apply creates one
from agents / the CLI. Unusable prompts pass the layer through.

Problem: comp.new/comp.settings clamp sizes to 30,000 px, frame rates to
0.001-1000 fps and motion-blur samples to 2-64, but reading a project
(.ecproj and .ecprojx, templates, recovery, offload) accepted any value:
a 4-billion-px comp, solid or footage frame, a 0 or 10^18 fps rate
(zero-length frames), a negative duration or 4 billion blur samples all
reached the renderer. New Solid, Layer Settings, Import Solid/Placeholder,
Crop Comp and PSD import set sizes without the upper bound, and comp
sizes past 2^32 wrapped.
Fix: one set of limits in effectcraft_project::limits. Project::from_json
brings every item (and proxy) within them; from_json_repaired also says
what it changed, which file.open returns as `repaired` and shows in a
toast, so the project still opens. Project::add_item applies the same
limits to every new item, and the size-setting commands clamp with the
shared helpers.

Problem: floating panels lived inside the main window only, so on a
two-screen setup no panel could go onto the second monitor (#486).
Fix: panel menu > Move Panel to New Window (and the agent/control command
`window.panelWindow {panel, window?}`) undocks the panel if needed and shows
its floating group in a native egui viewport the user can drag to any screen;
Move Panel to Main Window or closing the window brings it back. The window's
place and size are kept in the workspace (sanitised against hostile values)
and restored on the next start. Browser and test builds, which embed
viewports, show it as an in-app window.

Problem: nothing fuzzed project files. The hand-written .ecprojx XML reader
recursed once per nested <arr>/<obj> with no limit, so a deeply nested file
overflowed the stack and aborted the app instead of failing to open.
Fix: a dependency-free, deterministic, seeded mutation fuzzer for File > Open
(JSON and XML seeds from the demo, byte and JSON-structure mutations, the real
file.open path, first queries and a thumbnail render; each input under
catch_unwind with a deadline; bounded for cargo test, longer runs via env
vars). The XML reader now stops at the JSON reader's 128-level limit, with a
regression test.

Problem: scrubbing a long movie showed the frame under the pointer
seconds after the pointer stopped. Every viewer frame a free frame-pool
thread had started kept running: each seeked the movie's one decoder and
decoded up to a GOP, and the newest frame waited behind all of them on
the decoder's lock (45 min 1080p H.264/HEVC, GOP 250: 1.8-3.6 s for the
last frame of a drag; a single jump is 0.1-0.4 s). FilmCraft's decoder
already polls a cancellation flag, but nothing set one.
Fix: FootageSource::cancellable / called_off and CancellableFootage (a
per-render view whose frame reads run under the render's own flag, so
reads on other threads answer to the right render). MediaPool runs them
under filmcraft_media::cancel::with_cancel. The frame workers render
through it, and a newer viewer frame calls off the comp's running viewer
frames of other times. A called-off render is not cached (frames, disk,
layer cache). Drag latency is now 0.1-0.3 s.

A mouse click gives a Project row no keyboard focus, and the arrow keys
only move keyboard focus when a row already had it, so Delete /
Backspace, Cmd+D and Enter keep working for mouse users, also after an
arrow key moved the selection. Pin that down with a headless test.

Problem: app.scheduleTask(code, delay, true) queued the task and then
skipped it (eval_with_tasks: `if repeat { continue; }`), so repeating
tasks - what ScriptUI panels use for polling and refreshing - never ran.
One-shot tasks scheduled by handlers or in the Script Console never ran
either.
Fix: tasks live per script context (crates/script/src/tasks.rs) with a
due time. Frontends run the due ones every frame through the new
ScriptUi::run_tasks hook (the egui app does; agents and headless hosts
use the `script.runTasks` command). Script-host threads get a Tick
message, inline hosts (Script Console, web) run in their kept context.
A repeating task runs every `delay` ms until app.cancelTask, until it
throws (reported once, then cancelled), or until its owner goes: the
script's last window closing, or - for scripts without windows and the
console - the project being closed or replaced (ScriptUi::project_epoch).
Bounds: at least 50 ms between runs, at most 64 pending tasks per
script, one run per pass (no catch-up bursts), task code nested too
deeply is refused, the engine's loop and recursion limits apply. Ticks
only reach the hosts of the session that scheduled them.

Problem: with the Project panel focused the arrow keys did nothing (After
Effects selects the previous / next item, extends with Shift and opens /
closes folders with Right / Left). The custom-drawn rows, sort headers,
twirls, label swatches, proxy switches and footer buttons reached
AccessKit with no name or role, the empty list area and each row's name
cell were unnamed extra Tab stops, a Tab-focused row showed no focus
ring, and the arrows then moved egui's spatial focus instead.
Fix: Up / Down select the previous / next row (Shift extends from the
anchor), Right opens and Left closes the selected folder or selects the
parent; the moved-to row scrolls into view. A row with keyboard focus
keeps the arrows, focus follows the selection and the panel takes focus.
Rows are AccessKit tree items named "<name>, <type>" with selected,
level and expanded state; headers and row / footer buttons are named
buttons; one Tab stop per row and a focus ring.

Problem: the Render Queue had no single-file uncompressed output, so
handing a render to an external encoder meant a lossy codec, ProRes,
or an image sequence plus a separate WAV.
Fix: add the "QuickTime (Uncompressed)" Output Module format. Frames
are stored as QuickTime 'raw ' samples: 8-bit RGB (depth 24, rows
padded to even bytes) or ARGB with RGB + Alpha (depth 32), written
through FilmCraft's existing QuickTime muxer with PCM audio
(16/24-bit or float) like ProRes. Format name `uncompressed` on the
control channel; disk-space estimate and Sample Format menu included.

Problem: ScriptUI controls never sent mouse events to scripts.
addEventListener("mousedown" | "mouseup" | "mousemove" | "mouseover" |
"mouseout" | "click") listeners never ran, so custom-drawn controls
(onDraw + mouse, as DuScriptUI builds them) could not react to the pointer.
docs/plugins.md listed this as missing.
Fix: scriptui.js builds a ScriptUI MouseEvent (clientX/clientY relative to
the target, button, detail = click count, screenX/Y, modifier keys,
getModifierState, stopPropagation, preventDefault) and delivers it in the
capture, target and bubble phases. addEventListener takes the capture flag.
The parent walk is bounded, so a script-made parent cycle cannot hang it.
Each published control lists the mouse events a listener wants
(Widget::mouse, inherited from containers). The new scriptui.mouse
command dispatches one event with clamped, finite values and rejects
unknown types and disabled controls. The egui ScriptUI view hit-tests the
pointer over script windows and docked panels, skipping covered layers and
windows blocked by a modal dialog. It sends mouseover/mouseout,
mousemove, mousedown/mouseup with click counts, and a click carrying the
pointer details in place of the plain click, so a checkbox still toggles
once. Handlers run under the existing script limits; a throwing listener
reports an error and the window keeps working.

Problem: After Effects 26.2 spreads a Ctrl+Alt (Cmd+Opt) hot-text scrub
over the selected layers by selection order (first unchanged, last the
whole change, the ones between even shares). Our multi-layer scrub
(#491) always moved every selected layer by the same change.
Fix: prop.set takes `proportional` (with `selected` + `offset`); each
participating layer, the scrubbed one included, gets index/(n-1) of the
change in selection order, in one undo step; the first layer is left
alone (no key added). The Timeline value editor sends it while Ctrl+Alt
(Cmd+Opt) is held; that chord no longer fine-scrubs or unlinks Scale.

Problem: `$.evalFile` always threw, and `typeof BridgeTalk` was
`undefined`, so frameworks such as DuAEF failed during initialisation
when they load their modules or ask which application they run in.
Fix: `$.evalFile(file[, timeout])` evaluates a script file in the global
scope and returns its last value. Relative paths resolve against the
folder of the file being evaluated (the running script's for the
outermost call, else the project's); reads follow the same file gate,
16 MiB size cap and 32-deep nesting limit as `#include` (#759, shared
`scriptfile.rs`), and the bracket-depth check runs before parsing.
`BridgeTalk` names the host honestly (`appName` "effectcraft", its
version, `appSpecifier`, `isRunning` / `getSpecifier` / `getStatus` /
`getTargets` for ourselves only); `send()` throws a clear "not
supported" error instead of messaging other applications.

Problem: ExtendScript's preprocessor directives weren't understood, so a
script (or ScriptUI panel, or library such as DuAEF) failed to parse at
its first `#include`; `#target` / `#targetengine` / `#strict` lines broke
parsing too.
Fix: before a script runs, `include::expand` inlines `#include "f"` and
`//@include "f"` in place of the line, resolved against the including
file's folder, then the folders of the latest `#includepath "a;b"`.
Each file is inlined once (which also breaks cycles), nesting is limited
to 32, files are capped at 16 MiB (64 MiB in all), and reads follow the
scripts' file gate (the script's own folder, the project's folder, or
anywhere with Allow Scripts to Write Files). `#target`, `#targetengine`,
`#strict`, `#script` and `#engine` are dropped. Errors in the expanded
code are mapped back to the included file and its line. Scripts without
directives run unchanged. File resolution, the gate and the limits live
in `scriptfile.rs` for `$.evalFile` (#760) to share.

Problem: the Media Browser lists .mxf files, but File > Import's dialog
filtered them out and media::is_importable refused them, although the
pinned FilmCraft codecs behind crates/media already demux MXF (AVC,
MPEG-2 / XDCAM / D-10, VC-3 / DNxHD, ProRes, PCM audio) by content.
Fix: add "mxf" to VIDEO_EXTENSIONS and to the File > Import and Set
Proxy dialog filters. Tests check MPEG-2 4:2:2 long-GOP + 24-bit PCM and
DNxHD 36 MXF against ffmpeg frames (>35 dB, measured 64-67 dB), audio
level, and that the Import dialog offers MXF. AVI stays open: FilmCraft
has no AVI demuxer.

Problem: an animated WebP (e.g. ffmpeg -c:v libwebp_anim) imported as a
still and showed only its first frame; probe_bytes handed every WebP to
the still path. Found while measuring #719.
Fix: a webp_anim module, following the animated GIF path. Probing reads
the RIFF chunk headers (VP8X animation and alpha flags, one ANMF per
frame) and describes a WebP with two or more frames as Video footage
(codec "WebP", alpha Straight or Ignore from VP8X). Frame delays give the
rate: delays within 1 ms of each other read as the standard rate they
round to (24, 25, 29.97...), else 1000 / gcd of the delays so uneven
timing is exact; delays of 10 ms or less count as 100 ms as in browsers.
Frames are decoded once with the image crate's WebP AnimationDecoder and
cached in the pool's existing GIF slot; gif_anim::Anim now keeps frame
starts as Ticks and serves both formats. Canvas x frames beyond the
existing memory cap is refused before decoding; a damaged tail keeps the
frames before it; a file without frames is a clear decode error. Still
WebP stays a still.

Problem: the Media Browser listed .dpx files and After Effects imports
DPX and Cineon scans (stills and numbered sequences), but import
refused them: nothing could decode either format, and .cin was not even
an image to the browser, so its runs never grouped into sequences.
Fix: a small pure-Rust reader written from the public SMPTE 268M and
Kodak Cineon specifications (crates/media/src/dpx.rs): luma, RGB, RGBA
and ABGR at 8/10/12/16 bits, 10-bit filled method A/B, 12-bit in 16-bit
words, both byte orders, lines padded to 32-bit words, unrotated
orientations and the pixel aspect ratio; the codec names the transfer
(log, linear, ...) and code values are shown as stored. RLE, signed,
float, Y'CbCr, packed 10/12-bit and transposed files are refused with a
clear error; every header field is bounds-checked and the data length
verified before allocating. Probe and frame decode use it first;
is_importable, the Media Browser kinds and the import dialog list
.dpx/.cin.

Problem: EffectCraft shipped only 8 original text-animator presets against
After Effects' 621; there was no Transitions category (ranked gap #7).
Fix: an original preset library, crates/engine/presets/transitions.json
(23 presets on our own Transition effects and layer opacity: fades,
directional and diagonal wipes, clock and fan reveals, blinds and slats,
pixel/mosaic dissolves, card flips, CC grid, radial scale, line sweep and
jaws wipes; In and Out). New commands anim.applyBuiltinPreset (adds the
effects with values and keyframes from the current time, one undo step,
reports any path that doesn't fit) and anim.builtinPresets. Effects &
Presets lists them under * Animation Presets > Transitions; double-click
applies. Sidecar and ATTRIBUTION.md entry; gaps/effects-parity updated.

Problem: After Effects scripts call layers and property groups as a
shorthand for .property(nameOrIndex) (layer("ADBE Effect Parade"),
fxGroup(1), effect("Slider Control")("Slider")); Duik and many other
scripts use it throughout. EffectCraft's objects were Proxies around
plain objects, so each such call failed with "TypeError: not a callable
function".
Fix: Layer, PropertyGroup, MaskPropertyGroup and Property objects are
now Proxies around an arrow function carrying the object's state and
prototype (own name/length removed so the object's getters show). The
apply trap returns self.property(arg), so a call matches .property():
null when absent, Property returns null, and a missing name is the same
script error. instanceof, attribute access and script results are
unchanged; new on these objects stays a TypeError.

Problem: After Effects 26.3's font menu can show only variable fonts.
EffectCraft's font menus (Character panel, Properties ▸ Text) had no such
filter, and text.fonts / MCP list_fonts didn't say which families are
variable.
Fix: the font scan marks a face variable when its table directory has an
fvar table declaring axes (header read only, no extra file loading). The
font menu gets a "Variable fonts only" checkbox above the results; it
combines with the typed search, keeps the keyboard in the search field and
stays set while the app runs. text.fonts reports `variable` per family and
takes `{variable: true}`; list_fonts passes it through. Catalog rows for
ja, zh-Hans, zh-Hant and uk.

Problem: In Advanced 3D, an extruded shape or text layer was one mesh in
its paint colour. After Effects colours the front, bevel, side and back
of an extrusion separately (shape Contents ▸ Add ▸ Front/Bevel/Side/Back,
text Animate ▸ Front/Bevel/Side/Back), and EffectCraft had none of it.
Fix: The extruder can split its mesh by surface (front cap, bevel rings,
walls, back cap). Shape layers get Front / Bevel / Side / Back contents
items (layer.addShapeItem kinds frontColor…backColor, one item per
group, colouring every paint of the group and its nested groups; the
innermost wins). Text animators get Front / Bevel / Side / Back Color,
blended over the character's fill or stroke by the selection. Paints
with a surface colour render as one mesh per surface. Menus, the
Contents Add: pop-up and the menu translations list them. The other
surface material properties (Ambient, Diffuse, Specular, Metal,
Reflection, ...) remain.

Problem: with no working space and Working Gamma 2.4, a linear EXR still
converted with the sRGB curve (0.18 -> 0.4627, After Effects 0.4902):
float footage was sRGB-encoded at decode, before the render knew the
project's curve. Interpret As Linear Light on float footage then encoded
a second time (0.18 -> 0.7255).
Fix: FootageSource::frame_with asks for float footage with a FloatCurve
(sRGB, a pure 2.4 power curve, or as stored). The renderer asks for the
Working Gamma's curve when unmanaged, sRGB when managed, and the stored
values when Interpret As Linear Light encodes them afterwards.
MediaPool decodes float values that way (Preserve RGB still reads them
as stored) and caches each curve apart.

Problem: the Media Browser lists .tga and .hdr files (and groups them into
image sequences), but media::is_importable had neither extension and the
still decoder never tried them, so importing them failed.
Fix: enable the image crate's built-in tga and hdr decoders (no new
dependency), add both to STILL_EXTENSIONS and the File > Import dialog, and
pick a still's format by signature with an extension fallback, since Targa
has no signature. Radiance HDR is linear float light and is sRGB-encoded like
OpenEXR (super-white kept); Targa alpha goes through the existing
unlabeled-alpha interpretation.

Problem: `read_exr_channels` kept the exr crate's whole decoded image alive
while it built every f32 plane, and copied each channel through an extra
`Vec` (`values_as_f32().collect()`) before placing it. One decode of a
2560x1440 Blender file with 32 channels briefly held ~320 MB of samples next
to ~470 MB of planes, per concurrently decoded frame.
Fix: consume the decoded image channel by channel, so each channel's samples
are freed (or moved) as its plane is made. A channel that covers exactly the
display window is converted in one pass, and an f32 one (Cryptomatte ranks)
becomes its plane without a copy; other channels are placed into the display
window with bounds-checked indexing, as before. Keeping half channels as f16
and sizing the channel cache by bytes stay open.
Test: a full-window f32 channel's plane is the same allocation; f16 / u32
channels and offset or clipped data windows are placed as before.

Problem: with shape layers selected, the Tools bar's Fill Options / Stroke
Options (None, Solid Color, Linear Gradient, Radial Gradient, and the
swatch's Alt-click cycle) only changed the defaults for new shapes.
shape.fillStroke had no kind, so a selected layer's fill or stroke could
not be removed or turned into a gradient from the toolbar; it had to be
edited in the Timeline. The swatch also kept showing the tool's kind, not
the layer's.
Fix: shape.fillStroke takes fillType / strokeType. None switches the
layers' Fills and Gradient Fills (or Strokes) off; another kind switches
them on and turns them into that kind, keeping the uid and the
properties both kinds share (blend mode, opacity, width, dashes...), and
gives a group with paths and no such item one (gradients span the
group's paths). It reports the first layer's fillType / strokeType, and
the toolbar shows them. The kind picks in the options popup and the
Alt-click cycle apply to the selected shape layers, one undo step each.

Problem: After Effects 26 imports FBX models into Advanced 3D comps; File > Import rejected
.fbx, so FBX product shots and scenes could not be used.
Fix: a clean-room FBX 7.x reader in effectcraft-model (binary node records with 32/64-bit
offsets and zlib arrays, ASCII syntax) and a scene builder: meshes with normals, UVs and
per-polygon materials, the Model hierarchy with the SDK transform (pivots, offsets, pre/post
rotation, rotation order, geometric transform), Lambert/Phong materials onto
metallic-roughness with embedded or relative textures, and GlobalSettings axes turned to
Y-up. Wired into import, probing, the media browser and the file dialog. Hostile input
(truncation, corruption, huge arrays, deep nesting) fails with an error.

Problem: Mesh Warp keeps its Distortion Mesh in a hidden text parameter,
and the viewer only draws handles for point parameters (Bezier Warp's),
so with Mesh Warp selected there was no grid and nothing to drag: the
effect could not warp anything from the UI.
Fix: with a Mesh Warp effect (or one of its parameters) selected and
layer controls shown, the viewer draws the (rows+1)x(columns+1) grid
over the layer in effect space, with a handle on every vertex
(automation id viewer.meshWarp.<fx>.<row>.<col>). Dragging a vertex
writes its offset to the `mesh` parameter through prop.set, one undo
step per drag; a mesh that does not match Rows/Columns starts from the
undistorted grid, as it renders.

Problem: After Effects 26.3 pastes copied vector artwork as shape layers. Edit ▸ Paste only
knew the app's own clipboard, so SVG markup on the system clipboard was ignored; turning SVG
into shapes needed an imported footage file and Create Shapes from Vector Layer.
Fix: a new `edit.pasteSvg {svg, name?, comp?}` command builds a shape layer from SVG text with
the same conversion as Create Shapes from Vector Layer (paths, fills, strokes, gradients, clip
masks), above the selected layer with the SVG canvas centred in the comp, as one undo step;
oversized, non-SVG or shapeless text is rejected. In the UI, Ctrl/Cmd+V (and the native Edit ▸
Paste) run it when the system clipboard holds SVG. Copying in the app already replaces the
system clipboard with a note, so SVG there is newer than the app's clipboard.

Problem: After Effects 26.3 copies the current composition frame to the
system clipboard; EffectCraft could only write it to a file (Save Frame As).
Fix: new command comp.copyFrame {comp?, time?, scale?} renders the frame as
Save Frame As ▸ File does and emits Event::CopyImage (pixels not
serialized); the egui frontend puts it on the clipboard after checking the
buffer size. In the Composition menu (translated) and the viewer's context
menu; drivable by id over the control channel / MCP.

Problem: After Effects 26 imports STL models besides glTF and OBJ; we
refused .stl files, and the Media Browser and import dialog did not list
them as models.
Fix: a pure-Rust STL reader in effectcraft-model (binary and ASCII,
detected from the contents; several ASCII solids and polygon loops;
VisCAM/SolidView and Materialise Magics facet colours as plain
materials; Z-up turned to the model's Y-up; faceted normals from the
winding). Truncated, empty or non-finite input is an error, never a
crash. .stl is now a model extension for import, probing, the Media
Browser, the import dialog and the system report.

Problem: dropping a PSD/PSB file on the window imported it straight away.
The drop handler always passed `importAs` (Settings > Import > Default Drag
Import As) to `file.import`, and the Import Photoshop File form only opens
when `importAs` is missing, so the dialog that File > Import > File...
shows never appeared for drops.
Fix: a drop that includes a Photoshop file leaves `importAs` out, so the
form asks (other drops keep passing the preference). For dropped files the
form's Import Kind starts at Default Drag Import As; File > Import keeps
starting at Composition. The engine already falls back to the preference
for `drag` imports without `importAs`.

Problem: selection_hashes split the Selection on every comma before
stripping quotes, so a name containing a comma (Blender allows a material
called `Green, Glossy`) was cut into two names that match nothing, quoted
or not; only its `<hex>` hash selected it.
Fix: a small tokenizer splits at commas outside quotes. A name in double
or single quotes stays whole, a backslash takes the next character
literally (`Green\, Glossy`), and unquoted lists, wildcards and `<hex>`
hashes parse as before. The CPU effect and the GPU path share the function.

Problem: with the project's Time Display Style set to Frames, the
current-time display showed frame numbers but the Timeline ruler kept
labelling its ticks in seconds:frames (`00:15f`). The label format was
hard-coded and never read the project settings.
Fix: a `ruler_label` helper prints the frame number in Frames mode the
same way the current-time display does (`{:05}`, counted from Start
Numbering Frames At), and keeps seconds:frames for the other styles.
