The 1 GiB array limit counted wire bytes, but arrays are kept as f64/i64,
so boolean arrays grew 8x and 32-bit arrays 2x past it, and nothing bounded
the total across arrays. Every Model linked to a Geometry also built its own
copy of the mesh.
- A per-import Budget (2 GiB) is charged 8 bytes per array element before
the array is decompressed or widened, ASCII files are charged for their
parsed values, and each built mesh is charged for its vertex and index
data. Going past it fails the import with a clear error instead of an
allocation abort. parse_within/read_within take a lower limit for tests.
- Models instancing the same geometry with the same materials share one
mesh; a different material mapping still gets its own.

Accessor counts sized the f32/u32 output before the buffer view was looked
at, and offsets, strides and count * components used unchecked arithmetic,
so a few hundred bytes of JSON could request a multi-gigabyte allocation
(aborting the process) or overflow.
- Doc::layout checks count * components, adds the view and accessor offsets,
rejects a byteStride smaller than an element, and checks that the last
element ends inside the buffer, all with checked arithmetic, before
floats() or ints() allocate anything.
- Accessors without a buffer view (all zeros) are capped at 2^24 components.
- idx() and node index lists use usize::try_from instead of 'as usize'; an
image bufferView's end and a GLB chunk's end are computed with checked_add.

Depth-limited <use> expansion still let a few kilobytes of branching
references expand to 2^N elements. The parser now counts every element it
converts, <use> copies included, against a budget of max(500 000, twice the
file's own elements) and fails the import with Error::Xml once it is spent.
Targets currently being expanded are tracked, so mutual references stop at
the first repeat instead of nesting to the depth limit.

Project::comp_contains recursed through precomp layers with no visited
set or depth limit. A damaged project with a precomp cycle that doesn't
pass the queried comp (A and B nesting each other, C unrelated) recursed
until the stack ran out, which aborts the process ("stack overflow,
aborting"): it can't be caught as a command error, so unsaved work is
lost. layer.addItem checks it before adding a precomp, and the renderer
calls it for every nested comp and its audio. A long chain used the
stack the same way, and comps shared by many paths were walked once per
path (exponential for nested diamonds).
It is now an explicit stack with a visited set: same answers (a comp
contains itself; a target reached through a cycle is found), each comp
visited once, no recursion. The renderer already skips a precomp that
contains the comp being rendered, so a cyclic project now renders
instead of crashing; nothing is repaired on load.
Tests: project comp_contains_ends_on_cycles_long_chains_and_shared_
precomps (cycle with an unrelated target, self-nesting, a target through
a cycle, 40 levels of diamonds, a 20 000-comp chain); engine
a_project_with_a_precomp_cycle_opens_adds_and_renders_without_running_
out_of_stack (file.open, layer.addItem both ways, render). On main the
engine test aborts with a stack overflow.

Every socket operation locked one global table and held it through the
blocking write_all/flush, and streams had no write timeout (accepted
ones were explicitly blocking). A peer that stopped reading kept the
script blocked for good, and every other socket call, close included,
waited behind it.
- The table maps handles to Arc<Entry>, each with its own Mutex<Sock>.
The table is locked only to look a socket up, add or remove one,
never during network I/O, so one stalled socket doesn't hold up the
others.
- `write` sets a write timeout from the socket's `timeout` (10 s by
default, as reads) and reports "write timed out … the other side
isn't reading" instead of blocking. Failures to set the read or write
timeout, or to make an accepted stream blocking, are reported instead
of ignored.
- `close` removes the socket and shuts its stream down through a second
handle, so a call blocked on it fails at once.
Tests (socket.rs, native only): a 64 MB write to a loopback peer that
never reads fails with "timed out" after a 1 s timeout; while one socket
is blocked writing, another answers at once, and closing the blocked one
returns at once and ends its write. Both fail on main (the write never
gives up; the second socket waits on the table lock).

effectcraft-cli read its command line with std::env::args, which panics
on an argument that is not valid Unicode (a Latin-1 file name on Linux,
for example). `effectcraft-cli $'\xff'` or
`effectcraft-cli render-frame --out $'caf\xe9.png'` printed a panic from
std's env.rs and exited 101.
It now reads std::env::args_os and refuses such an argument as a usage
error (exit 2) that names it, before anything runs, like an unknown
option. A lossy copy is not used: every argument is a string here, and
`caf\u{fffd}.png` would read or write another file than the one named.
FilmCraft moved its CLI to args_os too (storytold/filmcraft#850).
Tests: a unit test for the conversion and a process test that runs the
CLI with a non-Unicode `--out` path (both unix-only). Before the fix the
process test fails (exit 101, not 2).

makehybrid -hfs gave every file in the image a com.apple.FinderInfo, so the app in the
DMG, and a copy installed from it, failed codesign --verify --strict --deep ("resource
fork, Finder information, or similar detritus not allowed"), though Gatekeeper accepts
it. Build the image as VectorCraft (#1085) and PdfCraft (#823) do now: hdiutil create
-srcfolder with a few tries for CI's "Resource busy", and verify the mounted app with
--strict --deep so the regression can't ship again.

With Warn User When Executing Files on, file.executeFile asks the
frontend first, and the frontend's answer re-runs it with
`confirmed: true`. That flag was taken from the parameters whoever
called, so a script could pass it itself (app.run('file.executeFile',
{path, confirmed: true}), also inside engine.batch) and the file opened
without the question, as long as the user had allowed file and network
access.
`confirmed` now counts only when the command isn't running for a script
(Session::running_for_script, which #590 uses for the same reason and
which stays set through nested batches). A script's request always gets
the question; the user's answer from the frontend's form still opens
the file; with the warning off nothing changes. The permission gate
itself is unchanged.
Tests: engine a_script_cannot_confirm_executing_a_file_for_itself
(execute_for_script directly and through engine.batch; the frontend's
confirmation; warning off) and the same through real JavaScript in the
script crate (app.run, app.run('engine.batch'), File.execute()). Both
fail on main.

A ReferenceError's first use was searched across the whole file, so a mention

The search now starts at the innermost script frame's line, and covers the whole

Out on an auto-Bezier key leaves its in side playing the same values,
and undo and redo restore each state. On a curved Position path with
unequal segment lengths and durations, In sets the key's speed from the
incoming path length, playback arrives faster than a constant speed, and
the out side plays as before.
A roving key passes speed straight through: the engine keeps both its
sides linear whenever the keys are edited (retime_roving), so an ease set
on one never plays. The panel still counted it as eased, so a selected
roving key showed "Eased 1 keyframe(s)" and stayed linear. The previous
pair-only panel did the same to a pair holding a roving key.
Selected roving keys are now left out of the work and counted. The
status names how many were skipped and that turning off Roving lets them
ease; when nothing else was selected, nothing changes and no undo step
opens. Fixed keys next to a roving key still ease.
Guide layers render only in their own comp's viewer: a nested renderer (precomp, collapsed
precomp in 2D, Classic 3D and Advanced 3D, comps read by effects, aux passes, the GPU walk's
resident precomps) now runs with guides off (Renderer::nested_opts), so a precomp's guide
layers no longer show in the parent comp's viewer or in a "Current Settings" render.
The Timeline layer and Composition viewer right-click menus (shared layer_menu) gain a
Guide Layer item (a plain toggle, no check mark) acting on the selection, and guide layers show a guide mark
before their name in the Timeline.

In After Effects solo is not time-dependent: while any AV layer is soloed,
non-soloed layers are excluded at every time. The renderer, nested/collapsed
3D paths, engine viewer helpers and viewer hit tests only counted solo layers
active at the current time, so outside the soloed layer's in-out range the
whole comp reappeared. Drop the time condition (audio already ignored it).
Update the #66 viewer regression test to the AE behaviour and add a render
test for it.

One middle key between unequal segments in each mode, with its
neighbours, times, values and selection unchanged and one undo restoring
it; first and last keys, keys that aren't neighbours and keys of several
properties; no undo step when nothing can ease; a Hold and an
auto-Bezier side kept as they play; per-dimension and motion-path
speeds on Scale and Position; and the pair's outer sides under In-Out
and Out. All but the unchanged API tests fail on main.
The panel eased only pairs of neighbouring selected keyframes, so a single
selected key (or keys that aren't neighbours) changed nothing.
An Ease selector (In, Out, In-Out; In-Out by default) now chooses the
sides of each selected key to ease. In eases a key's incoming side with
the curve's in side, Out its outgoing side with the curve's out side. A
side is eased when it has a neighbouring key, selected or not; the
neighbour is left as it is. Each side's speeds scale to the segment on
that side, so a key between a +100/s and a -40/s segment gets each its
own. The side not eased keeps playing as it did (easeSide, unchanged).
Sides are measured before any key changes, and no undo step opens when
no selected key has a segment on the chosen side; the status says which
neighbour is missing. A selected pair in In-Out still gets the whole
curve; its outer sides now ease too when they face an unselected key.
From Keys still reads the curve of a selected pair.
Every layer gets the Video switch (eye) in the Timeline (nulls, cameras and lights
were excluded by an is_av() check). A selected layer whose eye is off no longer
draws its box, handles, anchor or paths in the viewer. Alt-click on an eye and
Layer > Switches > Hide Other Video now take nulls along.

Alt-clicking a stopwatch added an expression, but its editor needed
another click before typing went into it. In After Effects the new
expression's field takes the keyboard at once, its text selected.
The pick whip's one-shot refocus (the editor takes the keyboard back
after a reference goes in) is now an ExprFocus request for any
property: which text to select, counted from the end, and the pass it
was asked for in. An Alt-click that adds an expression asks for it with
the whole text selected, so typing replaces it; the expression row is
opened if it was closed and scrolled into view (it is added below the
stopwatch's row, which can be the last one shown). The request is taken
once, when the editor is drawn, and dropped if its expression doesn't
appear or it isn't taken within a few passes, so it never takes the
keyboard later; an Alt-click that removes the expression clears it.
Tests (ui_inline_edit): typing straight after the Alt-click replaces
the new expression; a field clicked right after keeps the keyboard;
after removing it nothing has the keyboard; an expression added at the
Timeline's bottom brings its editor into view with the keyboard. Both
fail on main.

Preset rows (text, built-in and user .ecpreset) were click-only, so dragging
one onto a layer did nothing. They now start a DragPayload::Preset drag with
a ghost, and the Timeline, Composition viewer and Effect Controls apply the
preset to the layer it is dropped on, as they already do for effects and as
After Effects does.

A path's vertices and its two tangent arrays deserialize independently,
and nothing on load makes them agree. mask.new pads them, but a path
read from a project file may carry fewer tangents than vertices.
mask.addVertex checked its index against the vertices only and then
inserted into both tangent arrays, and mask.setVertex indexed the
tangent arrays after the same check, so either command panicked on
such a path (Vec insert/index out of bounds).
ShapePath::fit_tangents gives both arrays one entry per vertex (missing
tangents become corners, extras are dropped), and edit_path_counted
calls it on the value it edits, so every mask/shape-path vertex command
works on a consistent path. Other keyframes of an animated path were
already padded by apply_count_op when the vertex count changes.
Tests: two regression tests save a project, cut every mask path's
tangent arrays to one entry (static value and keyframes), reopen it
through Project::from_json and run setVertex and addVertex. Both panic
at mask.rs:209 without the fix.

Expansion was a fill plus a stroke 2·|expansion| wide, blended per pixel. Once the
expansion passed the shape's curvature radius the stroke's inner edge inverted: a
20 px circle expanded by 60 left a ring with the layer showing through the middle,
+600 cut only the original dot, and negative values left islands. The outline is
now offset with Offset Paths' geometry (round joins) and filled.

After Effects' Liquify shows Distortion ▸ Offset (x, y), and the renderer
already applied distortionMeshOffset — sampling the mesh at layer
coordinates minus the offset — but the parameter was declared hidden, so
users could neither see nor edit it, and #1194 read as 'the effect does
not work and the Offset option is missing'.
It is now a visible 2D Point control (still defaulting to 0,0, still
scriptable by its old path). Regression test: the spec exposes it as a
Point, a [20,0] offset moves the displaced-region centroid right by the
offset (the render differs, and the left of the shifted mesh is back to
untouched pixels), docs/effects.md refreshed via UPDATE_DOCS.
The reported flow — launch to the start screen, Open Demo Project, press
Space — does not reproduce on main: the demo comp activates, the start
screen closes, and playback starts. The behaviour already held (the
#279 menu-focus and #204 start-screen work fixed the neighbouring bugs),
so this lands as a regression test:
space_previews_after_opening_the_demo_from_home walks the exact flow
headlessly and asserts playing=true.
cargo test -p effectcraft-ui-egui --test ui_menus: 8 passed.
Looped *video* footage had a regression (#1045); a grouped PNG sequence
going through the same path — interpret a fresh placeholder to Loop 15,
drag it onto the timeline — did not. The behaviour is already correct on
main (addItem sizes a sequence layer from looped_duration, the pool's
frame_index wraps per cycle), so this is coverage, not a change:
interpret_footage_loop_extends_sequence_layers asserts a 15-loop of a
0.4 s sequence lands a 6 s layer.
cargo test -p effectcraft-engine --lib interpret_footage: 4 passed.
With the comp's and the layer's motion-blur switches on, the renderer
hands effects the shutter (angle, phase, samples) — CC Particle World
now uses it: eight to sixty-four sprite fields sampled across the shutter
are averaged into the transfer, so fast particles draw the motion trails
After Effects shows instead of one sharp frozen field.
The GPU particle pass defers to the CPU while the shutter is open
(catalog::gpu_supported), keeping the oracle identical on both backends.
Tests: sim::particle_world_motion_blur_trails (blurred differs from
sharp, lights more pixels, keeps alpha energy) and a catalog assertion
for the CPU gate; effects 450 and gpu 212 lib tests pass; fmt and
clippy -D warnings clean.
File > Dependencies > Find Missing Fonts listed a text layer whenever
its font matched no family name, while text layout finds a font by its
family, PostScript or full name (effectcraft_text::resolve). For a
layer set to the PostScript name Inter-Bold, EffectCraft draws the text
in Inter Bold, and text.fontFeatures reports the layer's font as not
missing. Find Missing Fonts listed that layer and a layer set to the
full name Inter SemiBold.
find_missing now lists a layer when effectcraft_text::resolve, which
text layout uses for each run, reports the layer's font as missing.
fonts_named_by_their_postscript_or_full_name_are_not_missing adds text
layers in Noto Serif, Inter-Bold, Inter SemiBold and a font that no face
has, and checks that Find Missing Fonts lists only the last one.
A Merge Paths item appended to a shape layer's Contents cleared every draw
collected so far, including fills and strokes inside groups above it, so
the layer's shapes vanished from the render. AE's rule is per group: only
paint items in the merge's own group above it are dropped. Draws now
record which contents level created them; the merge drops only its own
group's paint, and the group-bubbled draws keep rendering.
Adds a regression test (Merge Shapes and Add modes) that renders nothing
without the fix.
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.
Problem: on Windows two tests failed on main although the app is fine; they assumed
macOS/Linux path formats.
Fix: the CLI test strips the verbatim path prefix that canonicalize adds on Windows (a
child's current_dir() never reports it); the host sink test uses a drive-letter path on
Windows (a path rooted without a drive is joined to the home drive by the engine, the test
expected the current drive). Test code only.
