After Effects' `app.project.workingGamma` (2.2 or 2.4, ignored with a working space) sets
the curve an unmanaged project uses: at 2.2 the piecewise sRGB curve, at 2.4 a pure 2.4
power curve. EffectCraft always used sRGB, so linear EXRs (Interpret As Linear Light) from
a 2.4 project came out darker in the shadows (0.18 → 0.461 instead of 0.490).
- `ProjectSettings::working_gamma` (default 2.2, serde default for old projects).
- The colour pipe's unmanaged curve is the Working Gamma's (sRGB, or Rec. 709's pure 2.4
curve): Interpret As Linear Light encodes untagged footage with it and Blend Colors Using
1.0 Gamma linearizes with it; it is part of the pipe's cache key. The GPU path takes the
same conversions.
- `file.projectSettings {workingGamma: 2.2|2.4}` (other values are refused, as in AE),
`app.project.workingGamma` in scripts and a Working gamma choice in Project Settings.
Test: render test with linear 0.051 / 0.18 / 0.5 footage (0.290 / 0.490 / 0.749 at 2.4,
0.250 / 0.461 / 0.735 at 2.2, the values measured in AE), linear blending at 2.4, a working
space ignoring the setting, and the cache key.

Cause: Apply Color LUT's only parameter, `lut`, was ParamUi::Hidden (set only
through commands), so the effect could not be used from the UI. Effect
Controls also had no widget for any ParamUi::Text parameter (only EXtractoR's
channels had one), so Cryptomatte's Selection, the OCIO effects' config file /
file / config names and Colorama's Output Cycle could not be set either.
Fix: a new ParamUi::File { filters } for paths. Effect Controls shows the
file's name (None when empty) and a Choose... button that opens the host's
file dialog with those extensions and sets the path (prop.set, so agents use
the same command). As in After Effects, applying an effect with an empty file
parameter from the UI (Effect menu, Last Effect, drops, Effects & Presets)
opens the file dialog straight away; cancelling keeps the effect without a
file. Apply Color LUT's LUT (.cube) and the OCIO Config File (.ocio) and File
(.cube/.3dl/.csp/.cc/.ccc/.cdl/.spi1d/.spi3d/.spimtx) use it. Text
parameters get a single-line field that sets the value when it loses the
focus (Esc keeps the old text). Saved projects are upgraded on open: a
Hidden or Text parameter whose spec is now a File parameter takes the File
UI and keeps its path (effects::migrate). docs/effects.md regenerated.
This covers #473's first part (the Selection field); picking mattes in the
viewer, the layer popup from the file's metadata, the GPU path and quoted
commas are separate.
Tests: effects hidden_and_text_paths_become_file_parameters (migration); ui
file_and_text_parameters_have_widgets (the LUT is asked for on apply and
inverts red to cyan, the Choose... button picks another LUT, typing into
Cryptomatte's Selection sets it).

(cherry picked from commit 403863f703999d19d3a83d9976f76bdc7577e682)
Cause: float footage (OpenEXR, float TIFF) was always sRGB-encoded on
decode, and Interpret Footage could not turn that off, so an OCIO effect
on the layer converted values that were already encoded.
Fix: After Effects' Interpret Footage ▸ Color ▸ Preserve RGB
(Footage::preserve_rgb; file.interpretFootage {"preserveRgb": true}; a
checkbox in the Interpret Footage form; Remember / Apply Interpretation
carry it). The decoder keeps float values linear, and the working-space
conversion from the colour profile and Interpret As Linear Light don't
apply, so the file's values enter the composition unconverted. The media
cache key includes the flag, so both interpretations decode separately.
Tests: pool::preserve_rgb_reads_float_exr_values_unconverted,
tests_color::preserve_rgb_footage_is_not_converted (managed, linearized
and not), tests_proxy::guess_alpha_invert_and_linear_light (command,
render, Apply Interpretation).

After Effects' Interpret Footage has Start Timecode: Use Source File
Timecode, or Override Start, which changes the timecode the footage
shows and leaves its frames alone. The Start Frame field that trimmed or
padded a sequence's head isn't in After Effects, so it is replaced.
Footage.start_timecode (Override Start, in frames at the footage's
rate; None = Use Source, 0 as file timecode isn't read) relabels source
time: the Footage panel's current time and footage.info's `timecode`
count from it. file.interpretFootage takes `overrideStart` and
`startTimecode` (timecode, read at the footage's rate after any frame
rate change, or a frame number, 0 to 1e9). It applies to every footage
with time, not only sequences, and Reload keeps it. A sequence's frames
always run from its first file's number to its last.
Test: start_timecode_only_relabels_source_time (project),
interpret_footage_start_timecode_relabels_source_time (engine: the
reply, the Footage panel's timecode, frame numbers, Use Source, the
footage's rate, bad values, undo), Reload keeps it, and the Interpret
Footage fields in ui_drag_drop.

Effects: effect points on shape layers start at the layer centre (#227)
# Conflicts:
# crates/ui-egui/src/panels/puppet_tool.rs
# crates/ui-egui/src/panels/viewer.rs
After Effects shows a missing frame of an image sequence as a
placeholder (colour bars) and has no Hold Previous Frame or Skip choice
in Interpret Footage, so EffectCraft doesn't either.
Interpret Footage loses its Missing Frames field, file.interpretFootage
its missingFrames parameter, and Footage its missing_frames setting. A
gap in a numbered sequence's numbering always shows colour bars. A
sequence imported with Force Alphabetical Order still plays its files
one after another (its numbering doesn't count), as in After Effects;
that is now an internal Footage.alphabetical flag, set on import and
kept by Reload. The Interpret Footage note lists the missing frames.
Projects saved before this have no such field and open with the After
Effects behaviour: a sequence with gaps shows placeholders where it
used to close them up.
Test: project sequence unit tests (placeholders, alphabetical order,
projects saved without the flag), tests_sequence (Start Frame instead
of Hold / Skip), sequence_gaps_show_placeholders (media) and the
Interpret Footage fields in ui_drag_drop.

Image sequences were found only by the desktop media prober: one picked
numbered still brought its whole run, with no way to import just that
frame, picking every frame made one sequence item per frame, the browser
couldn't make sequences at all, and a gap in the numbering closed up
silently.
The engine now groups numbered stills itself (engine/src/sequence.rs):
one picked file brings its run from its folder, several picked files of
one run import as that range, a picked or dropped folder imports its
files with each run as a sequence, and Force Alphabetical Order takes
every image of that type in the folder by name. `file.import` takes
`sequence` (default on), `alphabetical` and `frameRate`; Replace Footage,
Reload, proxies and render outputs probe the same way. The media layer
probes one file; the browser lists its file table for the run and
registers every frame with its media pool.
File > Import > File... asks, like After Effects' "PNG Sequence"
checkbox, whether picked numbered stills import as a sequence, with
Force Alphabetical Order and the frame rate. Sequences are named
`shot_[0001-0250].png`.
Interpret Footage gains Missing Frames (Show Placeholder, colour bars as
in After Effects, the new default; Hold Previous Frame; Skip) and Start
Frame (the frame number at the footage's first frame: trims or pads the
head). Saved projects keep Skip, so their sequences play as before.
Form notes keep a readable width and the form fits its rows, so OK stays
in view. docs/footage.md explains importing footage and sequences.
Test: tests_sequence (engine: run, picked range, every frame, Sequence
off, folder, alphabetical, Interpret Footage Missing Frames / Start
Frame, Replace Footage and Reload), project sequence unit tests,
sequence_gaps_show_placeholders_hold_or_close_up (media),
import_dialog_offers_the_image_sequence_option and
dropped_frames_import_as_one_sequence_with_sequence_interpretation (UI).

Renders on macOS came out as `Comp 1.mov.ecproj`, and an image
sequence's every frame as `Comp 1_00001.png.ecproj`; another output
was `Comp 2.mov.mov`.
Cause: the save dialogs for anything but a project went through the
project dialog hook, which filters to `.ecproj`; macOS's save panel
appends the allowed extension to any other name. 0.4.0's Render Queue
Choose File… used it (#192 moved Output To to its own dialog since),
and Save Frame As, Save Current Preview, Export Lottie, Save a Copy As
XML, Collect Files, Watch Folder and the Premiere export form's Browse
still did. Nothing then fixed the name: Output To kept `.ecproj` (no
format claims it), and changing the format replaced only the last
extension (`Comp 2.mov.ecproj` → `Comp 2.mov.mov`). `[compName]` of a
comp named `Comp 2.mov` also doubled it.
Fix: `Hooks::save_dialog` asks the dialog for the default name's own
extension (`pick_save_file`), the project dialog only for projects or
on hosts without another (the web); the desktop dialog has no filter
for a name without an extension (folders). `OutputFormat::with_extension`
makes an output path end in the format's extension exactly once
(project extensions and repeats of the format's dropped, a missing one
added; `logo.png.mov` kept), used by Output To, format changes and
`resolve_output`, so existing projects and templates render to the
right name too. Output To picks the file type from the extension
before a stray `.ecproj`.
Test: output_names_end_in_the_format_extension_once (project),
output_to_ends_in_the_format_extension_once (engine) and
save_dialogs_offer_the_file_extension (ui); the engine and ui tests
fail with the fix reverted.

Shape and text layers have comp-sized effect bounds centred on their
origin, but effects measured positions from the origin: a point at its
default "layer centre" sat at the comp's bottom-right corner, so Twirl
on a centred shape changed nothing and Bulge only its bottom-right
quarter. As in After Effects, effects now work in effect space,
measured from the top-left of the layer's effect bounds.
The renderer moves the layer buffer into effect space for the whole
stack (Buf::rebase, CPU and GPU alike) and hands effects everything
else in it: masks, other layers' pixels for layer parameters (each in
its own effect space, so Set Matte and displacement maps see a whole
shape layer), the layer's own frames (layer_input, also what Puppet,
Roto Brush and the Layer panel read) and the comp camera
(CompScene::rebased). Layer bounds are now right for every effect, so
pin_rect and EffectEnv::bounds_origin go and layer_rect serves edge
pinning too. Adjustment layers still run on the comp below as it is.
effect_bounds / EvalCtx::effect_to_comp replace the repeated "comp size
when there is no source" code; the viewer's effect point handles and
eyedroppers, Puppet pins, the Layer panel (paint, Roto Brush) and the
tracker's Corner Pin output use them.
Project schema 2: opening a schema 1 project moves positions held by
effects on shape and text layers by half the comp size, so set points
keep their place (point parameters with keyframes, Paint paths and
clone positions, Puppet seeds and pins, Liquify and Roto Brush
strokes). Points still at their default become the layer centre;
expression controls, adjustment layers and expressions are left as
they are (docs/architecture.md). The disk cache's render version is
bumped.
Tests: default_effect_points_sit_at_the_centre_of_a_shape_layer and
layer_parameters_see_a_whole_shape_layer (render, both fail before),
effect_points_on_a_shape_layer (GPU vs CPU),
opening_a_schema_1_project_moves_shape_layer_effect_points_into_effect_space
(engine), and the effects migration tests.

build::default_label picked a new layer's label from its type alone
(comps Sandstone, images Lavender, ...), ignoring the label of the Project
item it was made from.
A layer made from an item (footage, comp, solid, 3D model) now copies the
item's label when it is created; every path that adds an item to a comp
(layer.addItem from the menus, Project panel, Timeline and viewer drops,
models, precomps, imports) builds its layer there. Layers keep their own
label when the item's changes later. Layers without an item keep the type
defaults.

Toggling a layer's Audio, Lock or Shy switch (or Hide Shy Layers) threw
away every cached frame: the RAM preview identity hashes each comp's
address, which any edit replaces, and the layer and disk cache keys
hashed every switch. None of these change pixels.
- Switches::pixels, Layer::same_pixels and Comp::same_pixels (exhaustive
field lists, so a new field must be considered) and Comp::pixel_form.
- Layer cache keys hash Switches::pixels; the disk cache's comp content
key hashes Comp::pixel_form.
- Frames::identity: when a new revision's comps draw the same pixels as
those of the comp's last new identity, that identity (and the project
holding its comps' addresses) is kept, so the frames stay, also when the
switch is toggled back.
With audio on, playback skipped frames that weren't rendered yet. Now the
sound waits: until the frames ahead (to the end of the preview, or what
fits in the RAM preview) are cached, every frame shows as it renders,
silently, like a preview without audio; then the sound starts in sync.
Reaching an uncached frame stops the sound instead of skipping frames.
Tests: audio_lock_and_shy_switches_keep_the_frames (frames.rs, nested
comps and toggling back), audio_lock_and_shy_keep_cached_layers (engine),
the disk key in tests_disk_cache, and
preview_with_audio_shows_every_frame_and_sounds_once_cached.

`Project::same_content` ignored `next_id`, so an edit that only took an id was dropped as a
no-op and the id could be handed out again (an edit may keep it beyond the project).
`guard::tests::the_session_survives_a_panicking_edit`, merged after M3.9, failed on main for
this reason. Ids now count; setting a value to what it already is still records nothing.

A precomp layer trimmed out (or time-remapped) past its nested comp's end kept drawing the
nested layers whose bars ran on. Like After Effects, the nested comp now shows nothing outside
its own span (`Comp::covers`), flattened, through a proxy or with Collapse Transformations, on
the CPU and the GPU (both go through `Renderer::source` / `collapse_into`).

Composition Settings ▸ Advanced has both options (they were missing from the model, the
renderer and the dialog):
- Preserve frame rate: nested in another comp, the comp shows only its own frames
(`EvalCtx::nested_time` floors the precomp layer's source time to the nested comp's frame
rate; used for the nested frame, its proxy, aux channels, collapsed transformations and the
viewer's internal wireframes), and the Render Queue renders it at its own rate whatever the
Frame Rate override (`RenderSettings::rate`).
- Preserve resolution: nested in a comp rendered at Half / Third / Quarter, it renders at full
size and the buffer's scale places it.
- `comp.settings {preserveFrameRate, preserveResolution}`, `comp.info` reports them, scripts
read and set `CompItem.preserveNestedFrameRate` / `preserveNestedResolution`, Pre-compose
copies them, and the dialog registers `dialog.comp.preserveFrameRate` /
`dialog.comp.preserveResolution`.

- `Project::to_file_json` writes `savedBy` (the EffectCraft version) ahead of the project and
checks that the text reads back before anything is written: JSON has no NaN or infinity, so
such a value made a file that saved but could never be opened. Save now fails with a message
and the file on disk is left as it was.
- Opening a project saved by a newer EffectCraft warns that settings this version doesn't know
are lost on saving; `file.open` reports `savedBy`. A file that isn't a project names itself in
the error.
- Increment and Save keeps the extension (`.ecprojx` stays XML); Save a Copy writes XML for
`.ecprojx` / `.xml` paths, like Save As.
- Docs: architecture (document model), parity.

- Pre-compose makes the new composition with the original's pixel aspect, background, motion
blur and frame blending settings and 3D renderer (`Comp::nested_like`); it kept only size,
rate and background.
- File ▸ New Comp from Selection records one undo step (two per item before) and takes each
item's pixel aspect. Several items selected open the New Composition from Selection dialog:
Single / Multiple Compositions, Use Dimensions From, Still Duration (default from Settings ▸
Import ▸ Still Footage), Add to Render Queue, Sequence Layers with Overlap, Duration and
Transition. `file.newCompFromSelection {single, dimensionsFrom, duration, addToRenderQueue,
sequence, overlap, overlapDuration, transition}`; `layer.addItem {duration}` for stills.
- Docs: parity.

- Quit and the window's close button, File ▸ New Project, Open Project, Open Recent, Close
Project, the demo project and a Home template show Save / Don't Save / Cancel when the
project has unsaved changes (Save asks for a path when untitled; cancelling that keeps the
project open). File ▸ Revert asks to discard. Before, all of them dropped unsaved work
without asking.
- The window title shows the project's path and `*` while it is modified.
- The modified mark follows undo: the session keeps the snapshot it last opened or saved
(`Session::saved_project`), so undoing, jumping in the History panel or rolling back a batch
to the saved state clears it.
- An edit that changes nothing (a value set to what it already is) records no undo step and
doesn't mark the project modified (`Project::same_content`, comparing untouched comps by
pointer).
- Agents' `engine.execute` / MCP calls are never asked; `ui.menu.invoke` shows the prompt like a
click (automation ids `dialog.unsaved.save` / `dontSave` / `revert` / `cancel`), and the
control channel's `app.quit {force: true}` skips it.
- Docs: architecture, agents, control protocol, parity.
