Clicking a History panel state ran Edit > Undo / Redo once per state. Each
step bumped the document revision, so the canvas could not tell what the
jump changed and recomposited the whole document (re-uploading every
changed layer on the GPU path).
history.selectState {state} returns the document to a state (numbered as
the panel lists them, redo states included) in one command: the history
moves by pointer swaps, the document becomes current once, with one
revision and the damage rect between start and target, and the targeted
layers restored as Undo restores them. The panel runs it once per click;
an open Free Transform refuses it (panel guard kept, and the transform
intercept greys and refuses it for every caller). A floating piece goes
back as with Undo instead of being dropped as a new step.

The Duplicate Layer dialog gains Photoshop's Document: New destination
with a document-Name field (As stays the copy's name, multi-select keeps
names, single group gets the Duplicate Group title). layer.duplicate
takes document index-or-new plus optional documentName, mirroring
channel.duplicate: the new document matches the source canvas, mode,
depth, resolution and profile, holds just the selected layers at their
positions, and becomes active. Smart-object contents are remapped within
the batch so copies are independent of the source. The dialog is fixed to
its content width so no dead strip remains.
* fix(text): split hyphenless PostScript style suffixes
A PostScript name without a hyphen kept its style in the guessed family:
`GmarketSansBold` became the family "Gmarket Sans Bold" at weight 400.
The guess now drops a trailing capitalised style word (Gmarket Sans, 700).
A lowercase ending ("Daylight") is not a style, and a style word after the
vendor tag MT stays in the legacy family ("Arial Rounded MT Bold").
Hyphenated names keep the last-hyphen parsing from #3878.
PSD import stores this guess when the exact face is absent. A legacy family
that ends in a style word without MT before it ("CooperBlack") is stored as
the shorter family (Cooper, 900) until the face is installed.

* fix(type): missing-font checks follow layout's PostScript resolution
When a run's stored family is not installed, layout draws it with its exact
PostScript face, or with the family guessed from that name if installed.
Missing-font detection compared only the stored family label, so such a run
was reported missing, and Replace Missing Fonts rewrote it whenever an
unresolved run shared the label. missing_fonts, missing_fonts_in_layer and
the replacement now use layout's decision.
#1406 already corrects the label when a PSD or Affinity file is opened with
the face installed, and #1844 finds exact faces outside the family prefix.
The label still stays on a run reopened from .pcraft after its font was
installed, on fonts that arrive after opening, and on a run created with
both "font" and "postscriptName". The tests take the .pcraft and command
paths.

Edit > Puppet Warp warped only a layer's pixels and left a linked mask
where it was, so the mask no longer lined up with the content. Free
Transform, Warp and Perspective Warp (#3083) already move a linked mask.
`puppet_warp_with_mask` solves the mesh once and moves the mask on the
same mesh: the mask under the mesh is lifted, deformed like the pixels
and laid over the rest; the area it leaves takes the mask's default and
the mask away from the mesh keeps its values. With a selection the mesh
covers only the lifted pixels, so only that part of the mask moves. An
unlinked mask stays put.
Tests: the moved stripe at 8/16/32-bit, undo, an unlinked mask, a
selection, and a hide-all mask in the algo crate. The engine tests fail
before the fix.

CanvasDisplay::texture_buffer (every CPU-path canvas upload of a linear

* Replace Color: Localized Color Clusters (points, localized, range)
image.adjustments.replaceColor takes the Localized Color Clusters of
Select › Color Range: "points" (where the colour was picked),
"localized" and "range" (% of the canvas's longer side). With clusters
on, the colour only matches near the points, through the same
color_range_samples as Color Range, so the same colour elsewhere in the
photo (a near-white background next to a cream garment) is left alone.
Without "localized" nothing changes. localized without points, and
malformed points, are refused.
The dialog part follows once the canvas eyedropper of #4247 is in.
Refs #4457
* Replace Color dialog: Localized Color Clusters and Range
The dialog gets Photoshop's Localized Color Clusters checkbox and its
Range slider (greyed while the box is off), and the canvas eyedropper
(#4247) now also records where the colour was picked (points), so the
localized match centres on that spot. The command's params list
localized, range and points as real keys in Photoshop's order.
Refs #4457
polygon_selection rasterised every lasso over the whole canvas (a
w×h f32 mask) and combined it over the whole canvas, whatever the
polygon's size.
Without feather it now rasterises the full-width band of rows the
polygon spans and combines over that band; Add and Subtract keep the
old selection outside it, Replace and Intersect leave it empty there,
exactly as the whole-canvas combine does. Full-width rows keep
`polygon`'s coverage bit-identical (its x arithmetic is relative to the
area's left edge, its y samples whole rows plus the same fractions);
a feathered lasso keeps the whole-canvas path, whose blur reaches past
the polygon. A test compares 24 random polygons, partly off the canvas,
in every mode, with and without anti-aliasing, against the old path.
Measured, a 2000-point lasso of a 400 px circle on 5472×3648: Replace
15–16 ms → 5 ms; Add to a selection unchanged (about 30 ms).

Like Photoshop, Cmd/Ctrl-clicking the Layers panel's New Layer button adds the
layer below the selected layer instead of above it. The Background stays at the
bottom: below it, the layer lands above it.
swatches.import named each imported group with unique_group, which
compares a candidate name with the library's groups one by one and
tries "Name", "Name 1", "Name 2" and so on until one is free. Groups
without a name all take the import's group name, so a file of n
unnamed groups cost about n^3/6 string comparisons. In a test build,
importing a file of 9,994 unnamed groups took about 4.5 minutes.
The import now builds the set of the library's group names once and
keeps the next number to try for each repeated name, as it already
does for swatch names. Group numbers still start at 1, and groups get
the same names as before.
unnamed_groups_are_numbered_in_linear_time imports such a file on a
thread of its own and fails when the import takes more than 20
seconds. repeated_group_names_take_the_first_free_number checks the
names when a group in the file has a name that the import already gave
to an earlier group.
PSD import keeps every placed layer as SmartSource::Linked { path:
<Idnt uuid> } so duplicates share the file and export stays
byte-stable, and info reported that as a link whose path is the uuid.
When the uuid has an embedded file (a liFD item in the preserved
lnk2/lnk3/lnkD blocks), the document's info now says
{"kind": "embedded", "fileName", "uuid"}; the new
linked::embedded_file_name finds it without copying the file.
Fixes#4842
Export Contents wrote the smart object's file as it was whatever the
path, so out.png held .pcraft or .psb data. With the contents' own
extension (or none) it still copies the file; with another one it opens
the contents and exports them in that format, as File > Export does
("converted": true, with the export's warnings). jpg/jpeg and tif/tiff
count as the same; an unknown extension is an error.
Fixes#4846
A stroke clones its brush settings on every pointer event
(StrokeRenderer::tail_preview clones the dab generator and the context,
each holding a BrushSettings), and a sampled tip's GrayTile carried its
samples in a Vec<u16>. With a large sampled tip, common in imported ABR
brushes, every pointer event copied the tip: measured 1.1 ms per event
for a 1500² tip and 3.8 ms for 2500², at 120+ events a second.
GrayTile's samples are now an Arc<[u16]>: a clone copies a pointer.
Nothing mutates a tile's samples after building it, so only
construction changes (`.into()`), and equality, serde and every read
are unchanged. Measured the same way: under 0.01 ms per event at any
tip size. Textures and patterns stored as GrayTile share alike.

- Preserve existing layer mask metadata (density, feather, linked, enabled) during select.refineEdge when outputting to layerMask.
- Honor explicit mask targeting (target: "mask") in refine_edge when both selection and mask exist.
- Add tests for mask metadata preservation.
document.inspect dumped an adjustment's internal model (enum name as
key, snake_case fields, 0..1 values), which no adjustment command takes.

* Liquify: simplify the brush-resize gesture condition
Same logic; clears clippy's nonminimal_bool on 1.96.
* Channels: keep the cached composite across view-only changes
Channel eye toggles bump the revision the cache was keyed on, so it was always dropped. The test only passed when the freed buffer came back at the same address, and failed under load.
A point outside 0..255 was moved onto the edge without a word, while the
error for bad points says they must be in 0..255; Photoshop refuses
them too. The error also named the command twice-quoted (`adjustment
`curves``); it is now `curves adjustment`.
Fixes#4867
select.colorRange takes {"select": "skinTones"}: a soft skin-tone model
in the YCbCr chroma plane (an ellipse along the skin run of Chai & Ngan,
1999) with a luminance gate, so near-black and near-white pixels drop
out. Fuzziness widens or narrows it as it does for Sampled Colors; the
selection modes, Invert and Sample All Layers work as for the other
presets. The dialog lists Skin Tones with Fuzziness enabled.
Detect Faces needs a face detector, which there is none of yet:
detectFaces: true is refused with a message instead of being ignored.
Fixes#4455
shape_split caches a stroked shape's fill and stroke rendered over the
canvas, for shapes with clipped layers: up to 32 entries of two
canvas-sized surfaces each, with no byte cap (several GB at 24 MP) and
nothing in Edit › Purge › All to clear it.
It now evicts least recently used entries until a new one fits both
the 32-entry cap and a 256 MiB pixel budget (an entry larger than the
whole budget is used and not kept), and Purge › All clears it as
"shape stroke cache", reporting the bytes like the other caches.

When appearance mode was toggled between dark and light with default
settings, PhotoCraft switched from Pro Medium (Pro layout) to Studio Light
(Studio layout), altering the UI and displaying a Fit button in the status
bar.
Now that the Photoshop Pro light brightness levels exist (#2661), default
the saved light theme to Pro Light so the Pro interface layout and status
bar are preserved when toggling appearance. Also map the "light" alias to
Pro Light and list the Pro options first under Light Theme preferences.

* feat(channels): Channel Options dialog to make alpha channels spot colours (#3761)
Double-clicking an alpha channel's thumbnail in the Channels panel now opens
Photoshop's Channel Options dialog (double-clicking the name still renames it):
Name, Color Indicates Masked Areas / Selected Areas / Spot Color, the overlay
or ink colour (Color Picker) and Opacity, which becomes Solidity for spot
channels. A saved selection can now be turned into a spot channel with its own
ink for screen-print separations. The row context menu gains Channel Options…
and Quick Mask Options…, and `channel.options` without params from a menu
opens the dialog on the targeted channel. OK runs the existing engine command,
so agents can still call it directly with params.

creates the spot channel from the selection, as before, and remembers the ink
and solidity for next time. `channel.newSpot` with params still runs the
engine directly for agents, the CLI and MCP. The engine's `next_alpha_name`
helper is now public so the dialog's name matches the engine's default.

The Print dialog's Printer field was free text, so you had to type the
spooler's exact queue name (e.g. HP_OfficeJet_3830_series). It's now a
dropdown, like Photoshop's: "Default printer (<name>)" first (value "",
as before), then every printer craft_print::printers() reports (CUPS
queues and driverless destinations, or Win32_Printer on Windows).
- engine: new query command `file.printers` → {printers:[{name, default}],
default}, no document needed, not journaled (same shape as DesignCraft's).
- ui: the dialog asks once per opening and keeps the list in `__printers`,
which never reaches file.print's params. Labels show `_` as spaces; the
exact queue name is what's sent. A remembered printer the spooler no
longer lists stays selectable.

Surface::convert / try_convert and map_color converted tile by
coordinate, and the ICC path (color_cmds::convert_surface) staged and
converted every coordinate's tile. A tile shared across the grid, such
as a filled background (one Arc for all of it), therefore came out as
one fresh tile per coordinate: a white 2048×1024 background went from
1 to 32 tile allocations, a 24 MP one to 384.
Each distinct tile is now converted once and the result shared by
every coordinate that shared the original. Pixels are unchanged; tests
compare against a per-pixel conversion and check the sharing for
convert, try_convert, map_color and Image › Mode › CMYK.

lift read the whole copied area into one f32 buffer (16 bytes per RGBA
pixel, about 366 MiB at 24 MP), multiplied in the selection and wrote
everything back into new tiles, so the clip shared nothing with the
layer: 273 ms for a plain Copy of a 24 MP layer and 341 ms after Select
All.
It now goes tile by tile. A source tile the copy takes whole (inside the
canvas, no selection or a fully selected tile, already in the clip's
format) is shared copy-on-write; the other tiles go through the old
per-pixel path one at a time. Measured on the same layer: 17 ms and
42 ms. The clip is bit-identical: the old whole-area version is kept as
the test oracle across depths, with and without alpha, no selection,
Select All, a partial feathered selection and one off the tile grid,
and content past the canvas.

* feat(color): Dot Gain 20%-compatible default working gray, as in Photoshop
Photoshop's default working gray is Dot Gain 20%, and its RGB -> Grayscale
measured in Photoshop 27.11 (default Color Settings) is D50 luminance
encoded with gamma 1.732: sRGB 64 / 128 / 192 grey and pure red become
46 / 105 / 177 / 107. PhotoCraft defaulted to sGray, which kept the sRGB
value (64 / 128 / 192 / 130), up to 24 levels off.
Adds the built-in "Dot Gain 20%-compatible (gamma 1.732, Photocraft)"
gray profile (id dot-gain-20-compat; our own fitted curve, not Adobe's
profile, the same gamma PhotoCraft already uses for gray adjustments) and
makes it the default working gray and the fallback for untagged gray
documents. sGray and Gray Gamma 2.2 stay selectable.
This changes a default: untagged gray documents now convert and display
as Photoshop shows them (midtones lighter than under sGray); documents with
an embedded profile are unchanged.

* OpenRaster: never overwrite an .ora with less than the document has (#3806)
File › Save wrote any document back to its .ora, though OpenRaster
drops adjustment layers, layer styles, vector masks and clipping,
applies masks and fill opacity to the pixels and rasterises type and
shape layers; the save then marked the document saved, so the edits
were lost without asking.
An OpenRaster file now counts as the document's own file only while
it holds everything in it. photocraft_io::ora_losses lists what a save
would leave out, from the same checks the writer warns with but
without encoding anything, and file_cmds::holds says whether a format
keeps the whole document (PSD, PSB and .pcraft always; OpenRaster when
nothing is lost). When it doesn't:
- File › Save opens Save As on a PSD of the same name, with a notice
listing what OpenRaster would drop, instead of overwriting the .ora;
- a save to an .ora path writes a copy, as Photoshop does for formats
that can't keep everything: the document keeps its file and stays
unsaved;
- automation (app.save, the headless doc.save) refuses a pathless save
with the reasons and treats an .ora save as a copy.
An sRGB profile is no longer reported as lost, as OpenRaster readers
assume sRGB. A plain document still saves back to its .ora.

* Lab and CMYK: Invert, Posterize and Threshold work on the document's channels
Photoshop applies these to each stored channel, not to RGB:
- Lab: Invert and Posterize work on L, a and b, and Threshold cuts on L
to a neutral black or white.
- CMYK: Invert and Posterize work on each ink, black included, so
paper inverts to 400% ink. Threshold gives paper or 100% black ink.
Adjustment layers now do the same:
- compose::adjust::apply_mode goes through the document's Lab or CMYK
channels.
- The GPU falls back to the CPU for these, as it already does for
Lab/CMYK Levels and Curves.
- The destructive Image > Adjustments path works on the stored samples
directly, so it is exact.
Photoshop oracles (lab/cmyk 8 and 16 bit), bad pixels before -> after:
- lab threshold: PASS (was 12%)
- lab invert: 72-99% -> 1%
- lab posterize: 89% -> 0.1%
- cmyk invert: 77% -> 10%
- cmyk posterize: 71% -> 9%
- cmyk threshold: 37% -> 1.6%
Floor 133 -> 139 (137 already passed on main).

* CMYK: Invert, Posterize and Threshold on the inks; 16-bit Lab Invert keeps greys neutral
Builds on main's adjust::apply_in (#4038):
- apply_in's mode dispatch gains CMYK. Invert and Posterize work on each
ink, black included, so paper inverts to 400% ink. Threshold gives
paper or 100% black ink alone. cmyk_channel_adjustment says which
adjustments do this.
- Lab Invert mirrors a and b around neutral at 16 bits; 8-bit bytes
still become 255 - v. stored_channels holds both rules, and
apply_lab uses it.
- Destructive Image > Adjustments on a Lab or CMYK layer works on its
stored channels directly, so it is exact; a selection mixes the
stored values.
- The GPU leaves CMYK Invert, Posterize and Threshold to the CPU.
Photoshop oracles, bad pixels:
- cmyk invert: 77% -> 10%
- cmyk posterize: 71% -> 9%
- cmyk threshold: 37% -> 1.6%
- lab16 invert: 52% -> 1.2%
The count stays at 145/258, which main already passes, so the floor
goes 133 -> 145.

Photoshop 27.11's round tip, measured on single dabs (hardness 0-100 in
steps of 10 at 40 px, checked at 100, 9, 7, 5, 3, 2 and 1 px): a solid
core of radius r0*R, then a Gaussian shoulder exp(-((d - r0) / s)^2) of
width s*R, both from a table by hardness. A soft tip reaches well past its
nominal radius (hardness 0 is a Gaussian of sigma 0.47 R: 8 % at 1.05 R);
PhotoCraft's (1 - t^2)^4 ended at R and kept far less coverage (a 40 px
hardness-0 dab held 251 coverage units against Photoshop's 542). The edge
stays at least ~1 px wide (0.3 R on small tips, never under 1/4 px).
exp is (1 - u/64)^64 by squaring, so it is the same on every platform.
Dab rectangles, reaches and the retouch footprint grow to the tip's reach
(tip_reach); the brush cursor's 50 % ring (half_coverage_radius) follows the
new curve. Tests that hard-coded the old curve now check measured values;
tests that bounded a stroke by the nominal radius use the reach.
Measured against Photoshop (max levels / mean): 40 px dabs, hardness 0-70:
70-156 / 12-15 -> 2-6.5 / <0.7; 100 px dabs 70-177 -> 2-27; strokes
(probe 13) soft and medium 20-60 px 133-178 / up to 17 -> 4-26 / <=0.5;
spacing sweeps 134-221 -> 7-9; soft Flow build-up 85 / 7.5 -> 5 / 0.16;
small 1-7 px total error lower in 21 of 30 cases (medium hardness at
2-5 px a little higher: a follow-up).

20 MP layer stored +82.5 MB per step for a ring of edge tiles.
blend_tile skips every pixel whose weight (selection × opacity) is
zero, so such a tile comes out byte-identical: keep the tile itself.
Mask::empty sits beside Mask::full. Measured on the same layer: the
stroke step now stores +17.5 MB and a 4000×3000 ellipse fill +14.2 MB
instead of +26.0 MB. The new test fails on the old code.

Session::apply_prefs set the shared text engine's missing-glyph
protection through photocraft_text::shared(), which blocks until the
system font scan that launch starts in the background is done. It runs
on the UI thread at launch and on every preferences change, so the first
frame waited for the rest of the scan: 248–257 ms on this machine
(release, launch order replayed), more with many fonts installed.
set_shared_missing_glyph_protection applies it at once when the engine
is built, and otherwise from one helper thread once the scan finishes.
Both read the newest setting under the engine's lock, so a late change
is never overwritten by an older one. Measured the same way: 0.1 ms.

Third-party action sets that load since 3204231 now play. Four TrueGrit
Texture Supply sets (Debaser, Distress Press, Halftone Zine Machine,
Transparency) go from 223 to 3 unmapped steps of 533 and play end to end.
- .atn import, 108 -> 112 events: Select and Mask (refineSelectionEdge),
Filter Gallery Spatter (GEfc), Ripple, Crystallize; targeting the layer
mask or composite channel, loading the targeted channel, Step
Backward/Forward, removeFromSelection (it silently imported as a plain
select), Pattern Fill layers (by name), nudges in points, Layer From
Background, Grayscale/Bitmap mode objects, Image Size by resolution.
- Engine: layer.translate units pt; layer.select mode remove;
select.loadSelection channel targeted; image.imageSize keepPrintSize;
layer.new.layerFromBackground ifPresent/select; pattern.import data.
New from Clipboard keeps the copied document's resolution (was 72 ppi).
- Filters: Spatter's Smoothness smooths the displacement (torn but
attached edges, as Photoshop's); Crystallize fills a cell from its point
instead of the average, so masks keep hard edges.
- UI: .pat opens/drops into the Patterns panel (no UI import existed).
- Docs: gaps G11, file-format and target-app parity.

* feat(vector): add shape from selection with simplify tolerance (#214)
- Add tolerance and simplifyTolerance parameter (clamped 0.5..10.0 px) to select.convertToShape.
- Wire select.convertToShape in filter_dialog::has_dialog to prompt for tolerance.
- Add tests for knot count tolerance scaling and selection requirement.
* rustfmt

The engine already took a source layer and Add/Subtract scale and offset,
but the dialog only offered the merged image and no way to set Scale or
Offset, so the frequency separation recipe (Subtract, Scale 2, Offset 128)
couldn't be done from the menu.
Fixes#3965
