* TIFF: open YCbCr images as RGB (#10316)
Scanners often write JPEG-compressed YCbCr TIFFs with 2x2 chroma
subsampling. The tiff crate decodes and upsamples them but returns raw
YCbCr samples, which the decoder rejected with "colour type YCbCr(8)".
The new tiff/ycbcr.rs converts them to RGB after decoding: JPEG data
uses the JFIF full-range BT.601 conversion (as libtiff does), other
compressions honour ReferenceBlackWhite and YCbCrCoefficients with the
TIFF defaults as fallback. 8 and 16-bit. YCbCr with extra samples, or
in other sample formats, fails with a clear unsupported error.

* TIFF YCbCr: test that YCbCrCoefficients set the luma weights
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* TIFF: YCbCr tags with the wrong value count use the defaults
tag_f64s now returns None unless the tag holds exactly n values, so a
YCbCrCoefficients or ReferenceBlackWhite tag with extra values falls
back to the TIFF defaults instead of being truncated.

* TIFF YCbCr: tests for tiled JPEG with ICC, big-endian 16-bit and planar
Covers the layouts the review asked for: a tiled 4:2:0 JPEG file with an
embedded profile (checked against an independent JPEG decoder), a
big-endian 16-bit file, and planar data in both byte orders.

* TIFF YCbCr: cite the formula sources and pin the green-channel choice
Documents where the conversion comes from: TIFF 6.0 Section 21
(YCbCrCoefficients, pp. 90-91) and libtiff's tif_color.c
(TIFFYCbCrToRGBInit, TIFFYCbCrtoRGB). Red and blue follow the spec;
green follows libtiff and adds Y unscaled, which matches the spec only
when the luma weights sum to 1. The module doc records this as a
deliberate compatibility choice, and a new test pins it: with weights
0.25/0.25/0.25, mid gray stays (128, 128, 128).

The doc merge left five Actions rows that disagreed (version 12 unsupported vs read; 120 vs
127 events). Found by CodeRabbit on #10776.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Supported table read from the batch's events.rs. The PRs' own sections (settings and command
options retained, Render defaults, steps kept disabled) are kept; the known-gaps tables that
#10702 and #10704 close are gone.

The Group F loader only mapped descriptors with an empty name and class
`null`, and nested shapes with an empty name. The reference application
names every step descriptor after the localized step (plus NUL), uses
the event code as its class and names nested shapes too, so every real
recorded Add To / Fade / Merge Layers ... step stayed a kept step and
never played (e.g. `addTo` with name "Add To\0", class `AddT` and a
nested `Rctn` named "\0"). The header is no longer checked; the shape
is matched by class only; key, order and enum checks stay strict.
IntW, Dstr and MrgL were registered with the string IDs
`interfaceWhite`, `distort` and none; the real ones are
`intersectWith`, `distribute` and `mergeLayers`, so steps written with
them stayed kept.

With our fix-up ea4112a4ce on top of the author's head 686f08c884. docs/atn.md kept from the batch (regenerated at the end); development.md and parity doc rows as unions.
With our fix-up 6ab24508d8 on top of the author's head 8988b6bfd0. Conflicts resolved: import lists as unions (bare_from/bare_to taken from steps_other, #10631), event table, tests and parity doc rows as unions.
With our fix-up 1f524c378b on top of the author's head 713aa92ba5. Resolved with main: the version check sits in main's parse_layout (it merged cleanly); doc comments combined; atn_contract no longer expects version 12 to be refused and pins that an empty version 12 set parses; one ATTRIBUTION row for all ATN fixtures; the fixture README states which files were encoded how; development.md no longer counts the fixtures.
Out-of-range Oil Paint and Smart Sharpen settings kept the step as a
Photoshop step; the reference application clamps them when the step
plays, so the import now clamps (stylization 10.5 -> 10, Amnt 500.5 % ->
500, Rds 0.05 px -> 0.1). Export still refuses out-of-range params.
Oil Paint's light direction (LghD) had no range: LghD 500 mapped and
saved back as 500. It now clamps to the command's -180..180 on import
(500 -> 180) and export refuses {"angle": 181}.
Smart Sharpen mapped the legacy Lens Blur form, which the command's
Gaussian sharpen does not play, and wrote every step as legacy Lens
Blur. It now follows the PSD smart-filter mapping (photocraft-io
smart_map): only useLegacy false + blur GsnB maps (noiseReduction ->
reduceNoise); the reference default (useLegacy true, lensBlur), Motion
Blur and legacy steps stay Photoshop steps; export writes useLegacy
false, Amnt, Rds, noiseReduction, blur GsnB.

With our fix-up 363e0f5e89 on top of the author's head 244082fb2c. Conflicts with main resolved as unions (new tests next to main's; parity doc revision rows).
Every remaining event recorded in the reference application through its
menus: Scale Effects, Create Layers, Frame and Artboards, all eleven
Stack Modes with their plug-in codes, video layer and frame commands,
Create Work Path, Find and Replace, Check Spelling, measurement scale
and Scale Marker, Close All, data sets (apply, import, export), Package,
Video Frames to Layers, Import Notes, Photomerge, Crop and Straighten
Photos, Conditional Mode Change and Fit Image. Close Others and Define
Variables record nothing.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Measured in the reference application: Batch source and destination keys
(open documents, Save and Close, override Open and Save As, suppress open
options), file naming output (the extension component only gets a dot as
the last component), processing order, flat output with subfolders, name
clashes, stop and log error modes with the log file format, and Esc.
What a normal recording names (layers by name, merged nudges and typing,
document offsets) and how it plays on another document. Trace Contour's
recorded keys and its 0..255 level; Quick Export records no step.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Measured in the reference application through its dialogs and recorded
actions: Shear point ranges and what ShrS/ShrE mean, the classic and the
new Gradient tool steps, Content-Aware Fill, Perspective Warp, Print,
Create Droplet and Sky Replacement descriptors, the mmdd/ddmm Batch date
components, and every layer comp reference form. Export As records no
step; Convert Stroke to Fill was not available in the measured version.

Addresses CodeRabbit on #10603: the Group A intro said every Filter Gallery effect loads as a
kept step, but Spatter is mapped; Custom's scale, offset and matrix cells now have their
measured ranges and the matrix has no default (a step carries all 25 cells).

Recorded in the reference application through its menus and read back from the saved Actions
panel, or returned by the dialog on OK: Custom, Fibers, Displace (with ranges), Color Lookup,
Shape Blur, Lighting Effects, Blur Gallery, Liquify, Camera Raw Filter, Vanishing Point,
Calculations; how Image Size, Canvas Size, Convert Mode and New Group are recorded. The Batch
descriptor with its file naming components, and the Actions panel menu and Playback Options.
Known gaps gain four rows: Convert Mode is saved with an enum the reference application
rejects, adjustment layer opacity on Make, Canvas Size in percent, Image Size in cm/inches.

- Known gaps: every exported step of the round-trip test was played in the reference
application (128 of 151 ran); six codes the mapping writes are wrong there (Vibrance and
Gradient Map events, Stroke Outside, Pass Through, canvas extension colour, Absolute
Colorimetric), and a document offset wraps around there.
- Reference forms: layers and documents by index, id, offset and ordinal, measured.
- Newer events: 63 candidates from the menu catalogue run in the reference application;
which need no settings, which were measured with settings, which need their dialog.
- Version 12 files: the older descriptor layout, checked on 325 real sets.

The contract tests no longer compiled on main (AtnItem::dictionary is now
Vec<u8>, so it is compared with b"Future event"), sat outside main's
tests/it layout, and the new atn.yml added six legs (two macOS) to every
PR against ci.yml's policy. Move the tests into tests/it so the existing
CI runs them, drop atn.yml and docs/atn-testing.md, keep main's ci.yml and
fuzz target, and note the committed fixtures in ATTRIBUTION.md.

Every mapped event was checked against the reference application: the corpus sets'
5 296 recorded steps and factory descriptors went through Load and Save Actions and were
compared with the original, and the forms PhotoCraft writes were played there. The new
section lists the settings mapped events still lose (transform reference point, show
only this layer, group names, clipping and colour labels on Make, shape layers, layer
via copy options, load selection from another layer, Background by property, Close that
asks, Lab Photo Filter colours) and the settings the commands do not have yet.
The supported table showed 15 direct adjustment events with shifted columns.

Importing an .abr or .grd whose name matched an existing group silently
deleted that group's user presets (edited or moved-in ones included); the
preset libraries are outside document history, so it could not be undone.
- brush.presets.importAbr / gradient.presets.importGrd: `replace` now
defaults to false; a taken group name imports beside it as "Kit (2)",
"Kit (3)"…, and the result's `group` names the one it landed in.
- UI: when the group already holds the user's presets, a prompt asks
Import as New Group (default) / Replace (can't be undone) / Cancel.
Agents drive it with ui.dialog.set {"choice":"replace"} / confirm / cancel.
- The status bar names the group the file landed in.
