Presets of our own (blocks 1300 and 1310) show what the Channel Info stores for a chosen
channel.
- EXtractoR: each record is a kind in byte 0 and the channel name. Named channels are
imported by name (Z, Z, Z renders equal to After Effects) and `(copy)` as the input's
own channel. The kind is byte 0 only: one definition default has `02 00 00 32`.
- IDentifier: byte 19 holds the chosen channel's name, `Object ID` when none is chosen.
After Effects lists only UINT channels and leaves the layer unchanged without one, which
the loss now says. A chosen `ObjectID` / `MaterialID` channel (any case) is the one
EffectCraft reads itself, so it imports without a loss; other names are reported.

The importer reported these three plug-ins as lost effects. They now
become EffectCraft's effects of the same name (parameter lists and data
layouts from our own After Effects 2026 project, docs/aep-format.md 3.7):
- CS Color Neutralizer -> ec.color.cccolorneutralizer: Pinning and Blend
w. Original. After Effects' correction is the per-range Red / Green /
Blue sliders (the Unbalance colours are pickers that keep no record),
plus View and Black / White Point; EffectCraft's effect has none of
them, so each is reported when stored.
- EXtractoR -> ec.3d.extractor: Black / White Point, UnMult, and the
default Channel Info (R, G, B, (copy)) as EffectCraft's R, G, B, A
(ExtractorChannels). Other channels are reported: only the default
layout is sampled.
- IDentifier -> ec.3d.identifier: Display by item name, ID. Its Channel
Info names only the channel type (Object ID, identifier_channel_type),
not the channel After Effects reads; After Effects left the sampled EXR
unchanged where EffectCraft draws the footage's object ID channel, so
every instance is reported.
On the sample project no effect is lost any more (29 before); the
parameters above are reported instead.

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).

Add After Effects project import with bounded parsing, explicit loss reports, and regression coverage.
