* aep: a layer's markers and Source Text are read where they are stored, not searched for (#3276)
A layer's marker list is a direct child of its root tdgp, and its Source Text record
btds a direct child of the ADBE Text Properties group. Markers walked the whole layer
subtree twice per layer (most layers have no marker list, so the walk always ran to the
end), and the three text-document accessors walked it once each.
* aep export: build the prototype template once, sort names with cached keys (#3277)
The template every export clones from is immutable; it is now built by the
first export of the process and kept (about 0.93 MB). The name sort builds
each natural key once instead of on every comparison. Root solids move into
the Solids folder instead of being copied. The two key-list rewrites share one
emit-local helper and match names compare as bytes instead of a decoded String.
Output is byte-identical.
* aep container: size sibling lists, hex and write output once; borrow plain .aepx attributes (#3275)
- read.rs: count the chunk headers of a sequence first and allocate the
children Vec once (bounded by the input and by the chunk limit).
- aepx.rs: decode_hex sizes its output once; attribute values without
an entity are borrowed instead of copied through decode_entities.
- typed.rs: PropGroup::get compares match names without building a
String (same result as the lossy compare, invalid UTF-8 included).
- write.rs: reserve the exact output size up front (try_reserve, so a
hand-built tree cannot abort on the allocation).
- read.rs, settings.rs, values.rs: use the shared bytes.rs readers.
Output is identical on the corpus (tree, written bytes, import).
* aep container: review fixes (#3275)
- read.rs: reserve with try_reserve_exact, so a raised chunk limit on a
small target cannot abort before parsing; the capped reservation and a
deep, retry-heavy nest of broken lists are pinned by tests.
- write.rs: a tree past the 32-bit container size fails with TooLarge
before anything is serialised.
- aepx.rs: drop an unneeded local and lifetime annotation.
* aep export: note what the concurrency test covers and why a failed template build is not kept (#3277)
* aep: text documents are read without a String per token, defaults built once (#3276)
TextDocument::parse reads a borrowed tree: names, bare words and strings without
escapes point into the body, keys are borrowed when they are /names, numbers parse from
the borrowed bytes, and dictionaries and arrays are moved into vectors of their exact size
when they close. The style and paragraph defaults are built once instead of per document.
parse_text_dict keeps its public TextValue result (the borrowed tree turned owned).
The old owning parser stays as a test-only oracle: a differential test compares both on
40 000 generated bodies (every key form the owned keys canonicalise, non-UTF-8 names,
escapes, unclosed strings, non-finite numbers), every cut of a realistic document and
nesting around the depth limit.
* aep: text-dict test builds its prefix without repeat(1) (#3276)
* aep: an escaped text string drops its byte order mark without a range drain (#3276)
* aep export: one key-time loop, key-list rewrite, tdmn decoder and byte writer for the listed modules (#3278)
In masks, shapes, styles, synth, fxsynth, base, camlight, skeleton,
textanim and tree (effects.rs, plan.rs and emit.rs keep their copies for
the follow-up work):
- New export/keys.rs: the key-time loop (timed_keys), the key-list rewrite
(fill_key_list, set_key_list, replace_cdat) and the spatial key record,
shared by masks, shapes and styles.
- One tdmn decoder (synth::tdmn_name, lossy UTF-8 up to the first NUL, as the
importer reads it) and one encoder (synth::tdmn) instead of the copies in
masks, styles, shapes, textanim, camlight and skeleton.
- One byte writer: tree::put, which errors. base::bytes, synth::tdb4,
synth::key_list, fxsynth::pard, masks::shph and the keyed path records write
through it; their fixed layouts keep the infallible signatures behind
tree::fixed, which logs, and a test builds every layout and requires no error.
- camlight::put_group uses the shared group split (tree::split_group), which
errors on a match name without a node instead of stopping quietly.
Export output is byte-identical on the corpus and the synthetic fixtures.
* aep export: pin the key-time loop's report, name the layout in the base::bytes log (#3278)
* aep export: review fixes for #3278
- tree::Fixed replaces tree::fixed: a fixed layout writes every field that
fits (as the old code did) and keeps the first error; finish() logs it
once with the layout's description and counts it per thread, so the
every-layout test cannot race with other tests.
- base::bytes logs one line naming its length and fields.
- masks::build_atom errors when the prototype has no Mask Shape instead of
dropping the path of every mask quietly.
- log sorted into the dependency list.
* aep: review fixes for #3276 text documents and markers
text_document reads the first btdk in the Source Text record, the documents
text_document_count counts. The old slot checks (same, is_neutral, undecoded_fields)
join the test oracle and are compared on 20 000 generated slot dictionaries; mixed
dictionary/array chains and a document left open at the depth limit join the parser
differential. An escaped string's byte order mark is drained without a copy.
* aep: remove test-only container accessors, share report and time-base code (#3281)
- Remove 35 public container accessors that only tests called (header,
camera/light, keys, footage, masks, shapes, version) and the dead
StyleMap::switch_name. Tests now check the importer's own reading of the
same bytes, or the decoder it uses; three import tests gain the values
the removed checks covered.
- Import and export reports share one loss entry (Loss<C>) with record,
total, count and summary; the JSON shape is pinned for both.
- Collector::lose_with builds a detail only below the detail cap (callers
switch later).
- The export uses the container's TimeBase; one NTSC table serves import
and export; TimeBase::frames saturates like units instead of returning 0.
* aep: review fixes for #3281: NTSC table beside TimeBase, real-path NTSC round trip, light and camera defaults on import, doc wording
* aep: drop a local check tool committed by mistake (#3281)
* aep export: sort keys as one compact byte string, bounded by the name (#3277)
The cached natural keys were Vecs of (bool, String, u128) segments: a 255-byte
name of alternating letters and digits took about 14 KB, held for every item at
once. Each key is now one byte string whose byte order is the natural order,
at most 5 bytes per name byte. Order and output are unchanged.
* aep container: check bdata digits and size before reserving (#3275)
decode_hex reserved the decoded size before it knew the value decodes,
so a large bdata with a bad digit reserved half its length first. It now
refuses a value larger than a chunk's 32-bit size field (TooLarge), checks
every digit in one vectorisable pass, and only then reserves, with
try_reserve_exact so a value that does not fit in memory is an error
instead of an abort.
* aep export: the every-layout test counts from a baseline, not from zero (#3278)
* aep export: correct the order the natural sort key doc gives for equal numbers (#3277)
* aep: the format notes name the accessors that remain (#3281)
* aep: the format notes name the 1 x 1 mask scale of text and shape layers (#3281)
* aep: read imports through a flat tree index (#3300)
Import reads an .aep through TreeIndex, one depth-first array of chunks that
borrows the file's bytes, instead of building and freeing the owned Chunk tree
(one Vec per list). The parser mirrors read::Parser step for step: the same
chunk count order against max_chunks, the same depth limit and opaque
fallbacks, the same errors. The typed view reads through Node, a handle to a
chunk of either tree, so the accessors work unchanged on both; .aepx keeps its
owned tree. Chunk, parse and write stay for export and editing.
The array starts small and doubles, never past what the input can hold or the
chunk limit allows; a failed allocation is TooLarge, a tree past u32 indices
TooManyChunks.
* aep export: the time remap and Transform keys use the shared key-list and match-name helpers; doc comments for the audit's functions (#3300)
* #3300: import .aepx through the flat index
The .aepx reader no longer builds the owned chunk tree element by
element. It decodes every body (hex, text, alias JSON, numbers) into
one buffer and records the chunks as depth-first entries whose bodies
are ranges of that buffer; TreeIndex::from_drafts turns them into the
index the importer reads, which borrows the buffer. read_aepx converts
that index into the owned tree in one pass.
The tree and the errors are those of the previous reader, which the
tests keep as the reference: generated and damaged documents under
seven limit sets, invalid UTF-8, hostile input, the fixture directory,
and imports through both. Bound tests pin the chunk list to the input
and the limit, and check that dropped content leaves nothing behind.
* #3300: read_aepx keeps its own owned-tree reader
read_aepx, read_aepx_with_limits and parse_any build the owned chunk
tree element by element again, as before the .aepx index, instead of
converting the index (which held the decoded buffer and the owned tree
at the same time). Import keeps the index reader. The tests now
compare the two production readers.
* #3300: test keys that round to the same time
* aep: compare the destination projects in the index-equivalence tests
both() and both_aepx() kept only the ImportResult of each path; they now keep
both destination Projects and assert structural and serialized equality, so a
layer or property value regression cannot pass on equal ids and reports.

* #3170: .aep import of the text animator Stroke Opacity and the Source Text expression
ADBE Text Stroke Opacity maps to the animator's strokeOpacity (percent, as
After Effects shows it). The Source Text expression is imported like any
property's (Utf8 text, tdb4 bytes 119/120); one whose flags give no state
is still reported. New committed fixture text-synthetic.aep, made in After
Effects 2026 with the working space None.
* #3170: .aep export of the Source Text expression and the text animator Stroke Opacity
The Source Text expression is written enabled or disabled as After Effects
stores it (tdb4 bytes 119/120, Utf8 after cdat); a disabled one is no longer
dropped without a report. strokeOpacity is written as ADBE Text Stroke
Opacity with the record After Effects wrote in text-synthetic.aep. A test
exports the fixture and imports it again.
* #3170: doc comments on the functions this change touches
* .aep import: Photoshop layers, placeholder effects, shape direction and Orientation expressions (#3087)
- A footage item showing one Photoshop layer shows that layer (record index, bounds and name
from its opti) and is named <layer>/<file>; an adjustment layer shows white where it applies
(opt-in through SourceLayer::adjustment_white, the direct Photoshop import is unchanged).
- Effects without a counterpart arrive as placeholder effects with their parameters, so
expressions reading them keep working; pseudo effects are no loss, a Dropdown Menu Control
becomes EffectCraft's. Slider ranges are checked, sizes are bounded.
- The loss prompt shows every detail line the report keeps and how many more there are.
- Shape direction and gradient highlight records in the default state are no loss.
- An expression on Orientation is imported with its value or keys.
* .aep import: report placeholder records and popup defaults that borrowed definitions leave open (#3087)
A value record the borrowed definitions do not name is reported instead of dropped, and a
borrowed popup without a record reports that its default item is not known (the first is used).
* Merge upstream/main into aep-import-bugs-3087
It arrived as a plain number, so Effect Controls neither dragged it over its
slider range nor clamped an edit to its valid range, as After Effects does.
A definition of parameters that are not kept, shared by many instances, was
walked again for each one without spending the budget; long popup item
names were kept per instance with each item counted once.
A pseudo effect's match name (Pseudo/0.25) was its group's match id, so a
match path to its parameters (keyframe paste, pick whip) was cut apart at
'/' and '.' and found nothing. The effect id stays the match name.
A skipped instance was reported through the capped detail list, so past 20 effect losses it was only counted. It now goes through the per-effect grouping under a key of its own, so it is named like any effect without a counterpart and is not merged into a kept instance's line.
A parameter past the budget was skipped and the next one tried, so the
rest of the effect, and every later effect without a counterpart, still
read its shared definitions and built popup items. The first parameter
that does not fit now ends the budget; a later effect without a
counterpart is reported on its own line without reading its definitions.
The docs now say that a placeholder's layer parameters report their keys
and expression.
Such an item is shown on the document, which the size does not confirm; it is now reported in unsupported_items, when the opti stores the document's size.
An item as big as its layer's bounds was taken for Retain Layer Sizes. When
the layer is also as big as the document but not at its corner, a
document-framed item has the same size, so it may show shifted. The opti
record holds the document's size at bytes 32 and 36 (1000, 1000 in every
record of the issue's project, the .psd's size); with it, that case is
reported. The layer still shows at its own bounds.
* .aep import: recognize French names for Levels' Channel and Clip popups
After Effects stores a popup's items in the UI's own language. A project saved
by a French After Effects writes "RVB", "Activé" and "Désactivé pour la
couleur 32 bpc" for Levels' Channel and Clip to Output Black / White.
EffectCraft's own popup options are English only, so these never matched by
name and the parameter fell back to its default, reported as "has no
counterpart".
Add popup_alias, a small table of confirmed After Effects labels in other
languages, used as a fallback in popup_mapping after the exact name match
fails. A synthetic test reproduces the three losses from a real file and
checks they are gone, with the same values as the English original.
* Cover Levels' French Red, Green and Blue popup items too
popup_alias only mapped "rvb" (RGB), so a French Levels with Red, Green or
Blue selected still lost that selection the same way. Add "rouge", "vert"
and "bleu" (from the same real pdnm list, confirmed against it); "Alpha" is
already the same word in both languages. A direct test on popup_alias covers
every item of the Channel popup it claims to know.

A popup of more than 1024 items kept only the first 1024 without a word, and
a valid selection past them was reported as damaged data. The cut is now
reported, and such a selection takes the first item and says so.

Footage made from one layer of a layered .psd showed the whole document and
was named after the file. Its opti (tag 8BPS) stores the layer: the record
index (BE i32 at 14, -1 for the merged image), the bounds (LE i32 at 78-93)
and the name (UTF-8 at 344). The item now shows that layer as EffectCraft's
own Photoshop import does (at its own size with Retain Layer Sizes), named
<layer>/<file>. A layer without pixels (an adjustment layer) keeps the merged
image and is reported.
Third-party plug-ins and pseudo effects (expression controls) were dropped on
import, so expressions reading them broke. Such an effect now arrives as an
effect group whose effect id is its After Effects match name: it renders
nothing, like a missing plug-in, and is listed by Find Missing Effects. It
holds the effect's parameters flat, named as in After Effects, with their
values, keys and expressions in the units After Effects' expressions read.
It is still reported (once per match name, "kept without rendering") and
counted in imported.placeholderEffects. The parameters and popup items kept
are bounded per import.

An Orientation with an expression was reported as "not decoded" and lost its
value and keys too. The expression is stored in the otst's tdbs like on any

* #3099: placed .ai pages fill the size After Effects stored; null anchors default to the corner
Footage of an .aep keeps the size After Effects stored for a placed PDF / Illustrator / EPS
file (the ArtBox, rounded up), and masks and anchors are measured against it. The page was
drawn as a PDF viewer frames it (CropBox, /Rotate) at its own size, scaled by the width ratio
at full resolution and stretched to the stored aspect below 3/4: masks too large, art off
centre, squeezed at half resolution.
- effectcraft-pdf: Framing::Placed / parse_page_framed (ArtBox clipped to the CropBox,
/Rotate ignored); boxes with a non-finite corner or span are not used
- Footage::placed_page (set by the .aep importer, serialized only when true): the page is
framed so and filled into the stored size (effectcraft_render::vector_fit), decoded,
continuously rasterised and in Create Shapes from Vector Layer; Reload keeps the size;
the frame cache keys it by size and framing
- .aep import/export: a null's absent Anchor Point is [0, 0], as After Effects reads it
- fixture ai-mask-3099.aep (own synthetic files, scrubbed, profiles stubbed) and tests
against After Effects 2026's read-back
* #3099: placed-page framing only for .ai and .pdf, EPS as before; doc comments
After Effects' sizing was measured with PDFs named .ai only; an EPS from an .aep keeps its
bounding box at its own size (listed as not measured in docs/gaps.md and docs/aep-import.md).
Doc comments on the touched functions.
* #3099: shapes from a placed page keep its frame (track matte)
Create Shapes from Vector Layer converted every path of a placed page, so bleed, art past the
artboard or the page's background showed where the footage's raster hides them. The layers it
makes from a placed page now take a hidden "<layer> Frame" shape layer (the footage's
width x height) as their Alpha track matte: drawn at the comp's resolution, its edge is the
raster's on shape and image layers alike. The command returns the frame layer's id too.
import_extra returned as soon as the arbitrary data was missing, so an
EXtractoR or IDentifier value record whose aRbs/aRbp payload is gone was
silently imported with the default channels; the payload may have chosen
other ones (Z). As for Lumetri's data parameters, a stored record without its
payload now adds a DamagedData loss; a parameter with no record stays the
silent default. The test now asserts the report.
After Effects' Channel Info kind 2 "(copy)" was imported as R, G, B or A.
EffectCraft's EXtractoR resolves those names through the footage's aux planes
first, and an OpenEXR keeps its own R/G/B/A planes, so "(copy)" read the
original file plane and dropped what an earlier effect did to the channel.
"(copy)" is now a reserved EXtractoR channel name (EXTRACTOR_COPY) that the
CPU and GPU renderers never look up in the aux planes: it is the input's own
channel of the same position. The importer writes it for kind 2.
Render regression: a modified input buffer with same-named R/G/B/A aux planes
of other values; GPU parity case with (copy) on an aux scene with R/G/B.
Refs #3170 (the Color Control part).
Some files have no project-level effect definition list (EfdG); it was seen in
17 projects, all from inside After Effects-made Motion Graphics templates. In
those, one instance per effect type keeps the full parameter definitions
(parT) and every other instance of the type has an empty parT. The others
were reported "without readable parameter definitions" and dropped (129
Color Controls of one template). The definition index now falls back to the
parT of the first instance of the same match name that has its own
(DefinitionSource::OtherInstance). Values still come from each instance's own
records; a value record that borrowed definitions do not name is reported
instead of vanishing.
The "Color ... holds an unreadable value" report came from 0.21.1, which read
only written records (tdsb 1). Reading default-state records (tdsb 3, #3126)
probably fixes it, but that is not confirmed for Color Control; a synthetic
test now pins a default-state colour record.
* AEP import: read image sequences without a filename prefix and with Force alphabetical order (#3174)
After Effects leaves out an empty filename prefix, so only one Utf8 (the
suffix, such as `.png`) follows the alias. The single part is now placed by
the first file name stored in `opti`: a name starting with it has it as the
prefix, one ending with it as the suffix; without that evidence a part
starting with `.` is the suffix and anything else is not read.
A sequence imported with Force alphabetical order stores its files in
`LIST StVc` (`StVS` with the count as a little-endian u32, then one Utf8 per
file name) instead of prefix and suffix; that list now replaces the
numbering. A list with a name that is not a plain file name (a separator, a
colon, `.` or `..`) is not read, since the names are joined to the folder.
A folder alias whose naming still cannot be read is reported as an import
loss instead of silently linking the folder. docs/aep-format.md describes
the empty prefix and StVc/StVS.
* AEP import: a listed sequence file name with a control character such as NUL is not read (#3174)
A NUL or another control character in a Force alphabetical order file name
now makes the whole list unreadable, like a separator or a dot directory, so
the import reports the naming instead of linking files that cannot exist.
* AEP import: a sequence file list without a readable count is not read (#3174)
After Effects writes the StVS count before the names. A StVc list without
StVS, or with one shorter than its u32, is now reported as unreadable naming
instead of taking every listed name.
* Doc comments for the functions this PR touches
A project file, an .aep, a timeline document or a Lottie file could give a
layer a time stretch of 1e-300 %, 0 or 1e300 %. Layer and comp time divide
by it and the audio mix read about usize::MAX source samples for one block,
which overflowed or tried a huge allocation and aborted the app.
- limits::stretch brings a stretch within After Effects' range (±1 % to
±9900 %, Layer.stretch in the scripting guide), sign kept; 0 and NaN are
100 %. Opening a project file corrects each layer and says so; a stretch
written as null (NaN in an auto-save) now opens instead of failing.
- .aep import and Lottie import clamp and report the stretch; timeline
import clamps the clip speed and warns.
- layer.timeStretch refuses a non-number and more than 9900 %; the Time
Stretch dialog's ranges match.
- Layer::layer_time / comp_time and the audio mix use the clamped stretch,
so a value set in memory can't divide by zero or read without bound.
Fixes#3247
After Effects' Puppet was dropped with a one-line "has the effect" loss. It now
arrives as EffectCraft's Puppet (ec.distort.puppet) in its place in the stack,
with its name and fx switch, and the report lists per mesh Triangles, Expansion
and per pin group (Deform, Overlap, Stiffness) the pins, keyed pins and atom
match names; entries outside the known tree are named once, and long lists stop
at ten with "and N more".
No pins are created: a pin's rest place is a vertex of the hidden mesh data and
the unit of its Position is unknown, and no corpus file holds a Puppet. The tree
(docs/aep-format.md 3.7) comes from an external scripting listing, not the
corpus; the sample that settles it is described there. The fx_inject test
helpers can now inject any effect instance, which the new tests use.
Refs #3093
A text layer's name followed its Source Text whenever the name started with "Text", so a user's
"Text Title" was replaced by the next text edit. The layer now records whether its name follows
the text (`name_follows_text`, optional in the project file). A new text layer named after its
text follows it; a name given at creation or by Rename (Enter, layer.rename, a script's
layer.name, Layer Settings' name) is the user's and stays; renaming to an empty name shows the
text again and follows it; committing the unchanged name changes nothing; copies keep the state.
On-canvas typing and layer.setText share the rule. The name is the text's first paragraph, which
ends at a line feed or a bare carriage return (After Effects' paragraph break).
Projects saved without the state keep the old rule for the names that followed: a name that is
empty, the text's own, or "Text"/"Text 2"... follows; any other name stays. AEP import records a
stored layer name as the user's and no name as following, and names an empty text layer without
a name "Text" instead of "Layer"; export writes no name for a following layer and keeps the name
the user gave, even when it equals the text.

#3119 (the base of this branch) is merged. Conflicts with the Cryptomatte
import (#3109) and the version report: Extra keeps Extractor, Identifier
and Cryptomatte, arbitrary.rs keeps ExtractorChannels /
identifier_channel_type next to CryptomatteData, the effect table counts
66, the docs keep both sides. The exporter from #2594 gets the Extractor

* AEP import: map the Cryptomatte plug-in to EffectCraft's Cryptomatte
The importer reported every instance of the free Cryptomatte plug-in
(match name `Cryptomatte`) as a lost effect. It now becomes
`ec.3d.cryptomatte`:
- CryptomatteData decodes the plug-in's Settings data (its own
little-endian layout, documented in docs/aep-format.md 3.7): the
Cryptomatte layer name and the selection text, both carried verbatim.
- Output maps to Display / Matte Only (Colors -> Colors, Matted RGBA ->
Matte, Matte Only -> Matte Only). Matted Colors, Selection Mode when on,
keys or expressions and anything else stored are reported, and
unreadable data is reported as damaged.
- EffectCraft's Cryptomatte gains a Layer Name text parameter. A layer the
footage has under exactly that name wins; otherwise the Layer popup
decides as before. The CPU, GPU and pick paths share one resolver
(AuxChannels::resolve_crypto_layer_named). Without it, plug-in layer
names such as Crypto_Material would silently fall back to the first
layer.
On a real production project this takes the effect losses from 132 to 44.

* AEP import: check Cryptomatte against an After Effects 2026 sample of our own
A sample made in After Effects 2026 (plug-in 2.6.6: a fresh effect,
Selection Mode on, each Output item, with read-backs and renders)
corrected three points of the mapping:
- Selection Mode on was dropped silently: After Effects writes it as a
default-state record (tdsb 3) holding 1, which the general reader does
not take. The Cryptomatte step reads that record itself and reports it.
- No Output record is now the plug-in's default Colors, also for an
instance that borrows the project's definition (every instance after
the first), which was reported as having no reliable default and fell
back to EffectCraft's Preview. Keyed or unreadable Output values fall
back to Colors too, still reported.
- Matted Colors imports as Display Matte (the same matte over the layer's
own colours) instead of Preview, still reported as an approximation.
docs/aep-format.md 3.7 gets the sampled Output default, the tdsb 3
Selection Mode record and the real fresh Settings data (an empty text of
length 1 and its MurmurHash3, twice, not cry1 and zeros); docs/aep-import.md
the render comparison with After Effects (Matted RGBA matches; Matte Only
differs in alpha; Colors with no layer chosen shows another layer).
Tests: the exact fresh Settings bytes, tdsb 3 Selection Mode, borrowed
definitions, and an opt-in test against the sample once it is in the
corpus (aep/cryptomatte.aep, ignored until the corpus pin includes it).

* AEP import: write Cryptomatte's popup items in the test as After Effects does
The injected Cryptomatte definition wrote `pdnm` and `fnam` as `LIST`
chunks. After Effects writes them as plain chunks whose body is chunks
(`NESTED_IDS`), and the reader only looks there, so the tests never read
Output's item names: they passed through the fallback for a definition
with four items and no `pdnm`, which uses the plug-in's own list.
The harness now writes both as After Effects does. New tests check that
the injected definition reads back with its items and instance name,
that Output is mapped by the item the stored index names (items in
another order, case, an unknown item), and that the fallback without a
`pdnm` still works. With the old `LIST` form, or with the mapping
ignoring the items, the new tests fail.

* AEP import: check Cryptomatte's layer and selection against presets of our own
The After Effects 2026 sample 1400 now has two preset compositions that choose a layer and
pick one object (box_red on CryptoObject) or one material (mat_paint on CryptoMaterial).
CryptomatteData reads both as they are; the picked tokens are the EXR manifest's hashes,
which EffectCraft's selection grammar reads the same as the names.
- The u32 at 108 is MurmurHash3 of the selection text with its NUL (three texts).
- A unit test pins the 127-byte preset data; the sample test now covers all eight
compositions with their layer and selection.
- Render check: EffectCraft's matte covers exactly the pixels After Effects draws as
selected, edge coverage within 0.0002. docs/aep-format.md 3.7 and docs/aep-import.md.

* Cryptomatte import: report damaged Settings and Selection Mode records
Review follow-ups for #3109:
- CryptomatteData refuses a selection text without its NUL and checks the zero byte
at 112 for an empty text too.
- A Settings record without its data, and a Selection Mode record whose value cannot
be read, are reported as damaged data, not taken as the default.
- Layer Name is the effect's last parameter, so the earlier parameters keep their
indexes and upgraded instances have the same order as new ones.
- A Cryptomatte layer name is matched as given before it is trimmed.

* Cryptomatte settings: require the selection's NUL to end its declared length

* Cryptomatte: match rank planes by the exact layer name
crypto_rank_planes looked planes up with a case-insensitive whole-name match, so
layers Crypto_A and crypto_a shared planes. The layer prefix now matches
case-sensitively; component letters still match in either case.

* AEP import: the report names the After Effects version of the file (#3115)
svap holds the version of the After Effects that wrote a project, head
bytes 4 to 7 the version the file is written for; Save a Copy As 25.x /
24.x of After Effects 2026 keeps svap and writes the older version into
head. AeVersion decodes the packed word (26.2.1x2), AepFile gains
file_version, saved_by_version and head_revision, and ImportReport gains
aeVersion (fileVersion, savedBy, tested; "unknown" when the file does not
say). A version outside 24 to 26 is imported as usual and gets a
limitation line, not a loss.
The 12 corpus families saved as 2026, 25.x and 24.x copies import to the
same project and report; docs/aep-format.md lists what the copies change
in the container. The fixture tests are ignored until the corpus holds
the files.

* AEP import: map HDR Highlight Compression, Echo, Linear Wipe, Offset and Color Stabilizer
The importer reported these five effects as lost. They now become
EffectCraft's effects of the same name with every parameter After Effects
stores (ranges, defaults and popup items from our own After Effects 2026
project, documented in docs/aep-format.md 3.7):
- ADBE HDR ToneMap -> ec.utility.hdrcompression (Amount)
- ADBE Echo -> ec.time.echo (Echo Time, Number Of Echoes, Starting
Intensity, Decay, Echo Operator by item name)
- ADBE Linear Wipe -> ec.transition.linearwipe
- ADBE Offset -> ec.distort.offset (Blend With Original is a stored 0..1
fraction, a percentage here)
- ADBE Deflicker -> ec.color.colorstabilizer (fresh Stabilize default
Levels, points, Sample Size)
A table row can name the range EffectCraft's effect works in
(ParamMap::limit): Echo values or keys beyond 255 echoes or a Decay of 1
are imported as stored and reported.
Tests build each effect into the committed synthetic.aep (fx_inject.rs,
which also checks its pard layout reads back). On the sample project the
effect losses go from 75 to 3 (the out-of-range Echo values).

Take recorded_value from #3134 for ordinary effects in import_mapped; the ValueRecord switch is gone (stored_value now reads default-state records too).
