* Right-click opens the Brush Preset picker (or erases), eraser-on-Background tests, README comma
- #75: the right mouse button never paints with the tool. With a painting tool it opens the
Brush Preset picker at the pointer (Photoshop). New preference Preferences › Tools ›
Right-click with painting tools (tools.rightClickWithPaintingTools: brushPicker | erase,
serde default brushPicker): with erase, a right drag with the Brush erases with the current
brush (one paint.stroke, one undo step, pen pressure/tilt as usual). ui.pointer accepts
"button": "secondary". New module ui-egui/src/paint_mouse.rs; picker body shared with the
options-bar chip.
- #76: the engine already paints the background colour when erasing a transparency-locked
layer (the Background); added tests at 8/16/32-bit in RGB/CMYK/Gray, with a selection, on a
normal layer (erases to transparency), on a transparency-locked layer, and through the UI.
- paint.stroke/pencil refuse coordinates beyond ±1e6 (an f64::MAX point ran out of memory).
- #73: test that the canvas hands the live stroke over to the committed document with no
frame lacking the stroke, refreshing only the stroke's rect.
- #69: README comma.

* Brush smoothing follows the options bar; the live stroke draws the catch-up tail (#73)
- The options-bar Smoothing % (pro and classic bars, Brush and Eraser) edits the session
brush's smoothing, which the live stroke and the committed paint.stroke both use; the
canvas no longer forces 0.3. The session brush starts at Photoshop's 10 %.
- With smoothing the brush lags the pointer and catches up when the stroke ends. LiveStroke
now draws that catch-up tail on every step (StrokeRenderer::tail_preview renders only the
tiles the tail touches; the previous step's tail is restored first), so the preview at the
last move equals the commit and nothing pops in on release. At 0 % there is no lag.
- Path › Stroke Path ignores smoothing (it strokes the exact geometry).
- Tests: paint tail_preview = finished stroke; canvas: 0 % preview = commit, 50 % preview =
commit with the end reaching the pointer, smoothing changes the stroke, commit equals
paint.stroke with that smoothing, no stale tails after sharp turns.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Smoothing is a per-tool option that brush presets keep
- Picking a brush preset (tools.setBrush / paint.* "preset", .abr import with select) keeps the
current smoothing amount and mode instead of the preset's (BrushSettings::picked_over),
as Photoshop's options bar does. An explicit smoothing alongside the preset still applies.
- The Brush and the Eraser each remember their smoothing (UiState smoothing_tool /
tool_smoothing, synced on tool switch before the options bar, the canvas and each stroke);
a tool seen for the first time starts at 10 %.
- Tests: engine presets keep 10 % / a user value with pulled-string mode; UI per-tool
smoothing across Brush/Eraser/other tools and on the first stroke after a switch.

* Adjustment dialogs: preview through a clipped adjustment layer on the GPU (#77)
While an Image › Adjustments dialog is open on a pixel layer, the canvas shows the
document with a temporary adjustment layer (the dialog's settings, the selection as
its mask) clipped to the target instead of re-running the command on a CPU proxy.
The canvas compositor draws it, so on the GPU canvas a change recomposites only the
target's area within the selection, and of that only what the view shows (the rest
catches up as the view moves); zoomed out on a large document it composites a copy
reduced to about screen resolution, built once per session. The base document and
region are built once per session; a change swaps the layer's adjustment in a
shallow copy. OK still runs the real command (one history step); Cancel drops it.
Kept on the CPU proxy where the layer composite can't match the command: non-pixel
or clipped targets, Blend If, visible untouched area, channel / Quick Mask targets,
CMYK/Lab/other modes, colour-making kinds in Grayscale, and documents the GPU
compositor doesn't cover. The navigator waits for settings to settle.
Tests: preview vs command within 1/255 (worst 0.37/255) for all 13 kinds at
8/16/32-bit, RGB and Gray, with/without selection; nothing changes outside the
region; dialog flow (cache, keys, damage, Cancel untouched, OK one step); GPU
parity of the preview and of the zoomed-out proxy.

* engine: display LUT without the 32-bit preview for the GPU canvas shader; keep values above 1.0 in texture_buffer
ColorState::gpu_canvas_lut leaves View > 32-bit Preview Options out of the display LUT
(the canvas shader applies exposure/gamma before it, on unclipped float texels), and
ColorState::hdr_preview returns the active preview. CanvasDisplay::texture_buffer no
longer clamps linear values to 1.0 before sRGB-encoding them (the 8-bit path clamps
afterwards with the same result).

* GPU canvas: Rgba16Float display texture for 16/32-bit documents (#46)
16- and 32-bit documents get an Rgba16Float canvas texture when the adapter can
sample, filter, render to and copy it (Rgba8Unorm stays for 8-bit documents, as the
fallback, and for high-bit documents over 100 MP, about 1.07 GB with mips), so smooth
gradients no longer band through 8 bits. Both the wgpu compositor path (encode pass
with 16F pipelines; no upper clamp) and the CPU band/rect upload path (f32 -> half
conversion, reused band buffer) write it. The 32-bit preview (exposure/gamma) moves
into the canvas shader, before the colour-management/proof LUT, so values above 1.0
are exposed into range instead of clipped. GpuCanvas::read_texels / texture_info for
tests and benchmarks; PHOTOCRAFT_CANVAS_F16=0/1 disables the float canvas / ignores
the budget. large_image_bench gains --depth 16|32.

User and imported .abr brush presets now survive a restart. The new
photocraft_engine::preset_store keeps one JSON file per preset group plus
content-addressed, deflated tip bitmaps (8-bit when the tip came from 8-bit
data) in <config dir>/Presets, and an index with group order and deleted
built-ins. Built-ins are never written; writes are atomic and bounded;
corrupt or oversized files are skipped with a warning and left on disk.
The desktop app loads the store on a background thread and attaches it when
it arrives; sessions without a store (CLI, MCP, web, tests) stay hermetic.
Brush preset mutations bump ToolState::presets_rev and the store syncs after
the command, rewriting only groups whose content changed.

The menu item ran select.colorRange immediately with the foreground
colour. It now opens a Color Range dialog: Select (Sampled Colors, the
hue families, Highlights / Midtones / Shadows, Out Of Gamut), Fuzziness,
Localized Color Clusters with Range, the tonal range sliders, the three
eyedroppers (on the preview; Shift adds, Alt subtracts), a grayscale
selection / image preview, Invert, OK and Cancel. Controls a mode
doesn't use are disabled. The preview and OK run the same engine
command, so the GUI, CLI and MCP select identically; OK is one history
step and Cancel leaves the selection untouched.

* Dialogs shrink back when their body gets shorter
The OK / Cancel row was laid out right-to-left with Align::Center, so it
filled the height left over from the previous frame's size and the
dialog could only ever grow. In the Color Range dialog, switching from
Midtones (two extra sliders) to Out Of Gamut or Sampled Colors left an
empty band around the buttons. Aligning the row to the top keeps it
exactly as tall as the buttons, so the dialog fits its content again.

* fix(ui): brush and eraser show the real stroke while drawing
While dragging, the Brush and Eraser drew a hard, flat egui polyline at
the brush width; the soft brush only appeared on release.
The engine's new `brush_cmds::LiveStroke` shares `paint.stroke`'s setup
and renders incrementally with `StrokeRenderer` onto a copy of the
document. The canvas shows that copy and recomposites only each step's
damage (preview key = stroke key + step). The commit passes the live
stroke's seed, so its pixels match the preview, and reuses the canvas so
only the stroke rect refreshes.
Downsampled CPU textures (documents over 4096 px, the Navigator) now
update partially too, aligned to the downsample factor, instead of
re-flattening the whole document.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Live stroke on the large-image stack: reduced CPU textures, pen tilt, display key
Adapts #64's live Brush/Eraser stroke to #71 (banded/reduced canvas), #66
(colour-managed display) and #74 (stylus tilt):
- compose: `render_reduced_damage` renders just the output pixels of
`render_reduced` whose source area meets a damage rect, with bit-identical
values (same spans, same summation order). The CPU canvas texture of a
document over 4096 px now updates partially from it (strokes, live steps,
any damaged edit) instead of #64's factor-aligned `downsample`, which
didn't match #71's area-reduced texture; uploads still go through
`display_image` (document -> monitor profile).
- ui-egui: the live stroke feeds each point's pen tilt/rotation (the same
values `Stylus::stroke_points` gives the commit), so tilt-driven brushes
preview what they commit; the first points come from the drag after
`Stylus::begin_stroke`.
- Preview keys keep #66's display key folded in; `damage_since` un-folds
the cached keys to compare against the live stroke's steps, and the commit
resets the caches to the document's key (raw 0 ^ display key).
- Stroke counter is masked so live keys stay in their 2^44 band.
6000x4000, 120 px soft brush, release: LiveStroke::push 0.72 ms mean
(p95 1.0), GPU damage refresh 1.6 ms mean (p95 4.7); CPU reduced-texture
rect 0.75 ms vs 135 ms for the full 3000x2000 reduction it replaces.

* Compose: render in place and in bands; area-reduced and proxy thumbnails
render_tiled wrote every tile into a Vec and then copied them into the output:
two full-size float copies (6.3 GB for a 14000² document). Tiles are now
written straight into the output band by band.
New streaming APIs so large documents never need a full-size float
composite: render_bands (sink per band of ~8 MP), render_reduced (banded
area average, bit-identical to the old flatten-then-average thumbnail) and
flatten_to_surface (Flatten Image, Merge Visible, Copy Merged and the other
flattened-surface users).
thumbnail() reduces a downsampled proxy (moved from ui-egui to
compose::proxy, now also scaling spot channels) for documents over 16 MP
when that is faithful (no layer effects or vector masks), so navigator,
channel and histogram thumbnails of a 196 MP document cost milliseconds.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* GPU canvas: request the adapter's real limits; banded CPU fallback; navigator thumbnail
egui-wgpu asks for an 8192 px texture limit, so the wgpu compositor rejected
every document wider or taller than 8192 px and each refresh fell back to a
full CPU flatten. The desktop and web apps now request the adapter's own
max_texture_dimension_2d and max_buffer_size (gpu_canvas::use_adapter_limits);
the benches use the same limits.
The CPU fallback (documents beyond the GPU limit, or features it lacks) is
GpuCanvas::refresh: it renders and uploads the composite band by band
instead of a full float composite plus a full RGBA8 copy. The CPU canvas
texture is reduced in bands too, and the Navigator on the GPU canvas uses a
cached thumbnail instead of a full-resolution CPU composite per revision.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* IO: banded export and import; no full-size copies in encoders; larger decode limits
- Flat export renders the composite in bands and quantises each band; alpha
is dropped in place when every pixel is opaque. The single-layer native
path copies surface rows a band at a time (no f32 read_region and no
per-pixel Vec). Buffers come from try_reserve: Err, not an abort.
- PSD export encodes the merged image band by band into its planes (no
flatten, no second plane copy); near-opaque documents are re-encoded
without the white matte so the output is unchanged. Layer interleaved
bytes are freed before their planes are compressed.
- Flat import converts in ~32 MB bands (and not at all when already RGBA);
the PSD merged-image un-matte works per tile row.
- Encoders borrow the image when no conversion is needed (Image::converted)
instead of cloning it; PNG only copies 16-bit data for the byte swap.
- Decode limits: 2^30 pixels and 8 GiB on 64-bit targets (a 20000² JPEG
was refused at 2^28).

* Filters: write tile results in memory-bounded groups
apply_tiled collected every tile's float result before writing any (3.1 GB
for a 14000² layer). Results are now produced and written in groups of about
256 MB (at least one tile per core).

* History: bound pixel memory by Preferences > Performance > Memory Usage
History::max_bytes caps the current document's tiles plus the tiles only
history holds (layers, masks, alpha channels); History::trim drops the
oldest states beyond it after every recorded step and when preferences
change, always keeping the last step undoable. The engine sets it from
memory_usage_mb, which was unused.

discontiguous / contiguous / find-edges limits, tolerance, protect

* Image Rotation, Canvas Size, Crop, Trim and Image Size move vector geometry
Canvas-wide operations remapped only pixels: type, shape and smart-object
transforms, vector masks, saved/work paths, guides, slices, notes and
Count/Ruler marks stayed put, so they jumped back on the next re-render.
New engine module canvas_geom applies the canvas map to all non-pixel
geometry. 90°/180°/flip turns remap every pixel surface exactly (incl.
type/shape/smart/fill caches and smart filter masks) and move geometry
through the matching affine; guides swap orientation under 90° turns;
rect/ellipse/line live shapes stay live; gradient fill angles follow.
Canvas Size/Crop/Trim translate geometry (shapes re-render for the new
canvas), Image Size scales it and re-renders vectors, Arbitrary rotation
also moves unlinked vector masks and document marks. Layer effect angles
stay (Global Light), as in Photoshop.
Tests compare the CPU composite of a rotated document (type, shapes,
vector mask, smart object) against the rotated flattened original, also
after re-rendering everything from geometry, at 8/16/32-bit RGB, CMYK
and Gray.

* raw: clean-room camera raw decoder and developer (photocraft-raw)
A new standalone crate (no workspace deps, wasm-safe, no unsafe) written
from TIFF 6.0, TIFF/EP, the DNG 1.7 spec, ITU-T T.81 Annex H and published
demosaicing papers:
- Lossless JPEG (LJ92) decoder: predictors 1-7, point transform, restart
intervals, combined Huffman+extra-bits fast table.
- DNG: uncompressed (8-16 bit, packed) and LJ92, strips and tiles, CFA and
LinearRaw, linearization, black level (repeat, deltas), white level,
active area, default crop, ColorMatrix/CameraCalibration/ForwardMatrix
interpolation by CCT, AnalogBalance, AsShotNeutral/WhiteXY,
BaselineExposure, orientation.
- CR2 (LJ92 slices, SensorInfo borders, ColorData as-shot WB, measured
black) and TIFF/EP raws (NEF/ARW/PEF uncompressed or LJ92, incl. Sony
lossless ARW tiles, Nikon/Sony documented black and WB tags).
- Develop: black/white scaling, WB with highlight clipping, bilinear /
Malvar-He-Cutler / AHD demosaic (rayon bands, sequential on wasm),
camera -> XYZ D50 -> ProPhoto, exposure, gamma 1.8, 16-bit, orientation.
- Embedded JPEG preview finder; clear Unsupported errors for CR3, RAF,
ORF, RW2, vendor-compressed NEF/ARW/PEF, lossy/JXL/float DNG, X-Trans.
- Limits checked before every allocation; testgen feature with an LJ92
encoder and DNG/CR2/TIFF-EP writers; round-trip, colour-reference,
truncation and corruption tests.
Registered as a standalone crate in xtask layers.

* io: open camera raws through photocraft-raw (16-bit ProPhoto), preview fallback
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* raw: DNG GainMap opcode, fuzz targets, stress tools; open raws from the apps
- Apply DNG OpcodeList2 GainMap (lens shading, e.g. phone DNGs); report other opcodes.
- cargo-fuzz targets (develop, ljpeg) and a mutation stress example.
- Raw extensions in the desktop/web open dialogs and the batch folder list.
- file.open returns the import notes (how a raw was developed, preview fallback).
- codecs: the camera raw refusal points at photocraft-raw.

* File open/save: set the path everywhere, Open Recent, show errors and import/export warnings
File › Open, drag-and-drop onto the window and launch paths now share
PhotocraftApp::open_file: the document is named after the file (not the full
path), keeps its path so File › Save writes back, and goes to Open Recent.
Failures are shown as errors (status bar + a non-blocking notice).
Import/export warnings from photocraft-io are no longer thrown away: they show
in the status bar and in a dismissable notice (native and web), and the
control protocol returns them from app.open/app.save/file.open/file.save/
file.saveAs/file.saveACopy. .pcraft is in the Open and Save filters, and
File › Save writes .pcraft documents in place.

* macOS: open files from Finder, Open With and the Dock (Apple events)
Finder double-click, Open With, drops on the Dock icon and open -a deliver
files as kAEOpenDocuments Apple events, not argv, and winit 0.30 ignores them.
Register an NSAppleEventManager handler through the small fmv-macos-events
crate (MIT OR Apache-2.0, 168 lines, audited, pinned =0.1.0; it keeps the
Objective-C unsafe out of our forbid(unsafe_code) workspace) before the event
loop starts, so both the launching event and later ones reach the UI as
OsEvent::Open; the window is focused. The quit Apple event goes through the
normal close path.

* Shortcuts match like Photoshop: Ctrl/Cmd + '+' zooms, exact modifiers, clipboard keys
- Cmd/Ctrl+'=' also matches '+' (Shift+= on US layouts, numpad +, the '+' key on
Nordic/German layouts); Delete also matches Backspace (the Mac delete key).
- Modifiers match exactly (Cmd+Alt+I no longer runs Cmd+I); Shift shortcuts on
punctuation match the shifted character (Cmd+Shift+; arrives as Cmd+':').
- Zoom In/Out, Fit on Screen and 100% stay live while a dialog or a non-text
widget has focus.
- clipboard_keys: egui-winit turns Cmd+C/X/V into Copy/Cut/Paste events (and
drops Cmd+V when the clipboard holds an image); outside text fields they
become key presses again so Edit > Copy/Cut/Paste/Copy Merged run.
- Snapping: Ctrl (Windows) / Control (Mac) disables snapping only while held
during the drag, not at the press (Ctrl-click belongs to the tool).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Dialogs: no cancel on outside click; canvas pans and zooms under them
- Disable egui's keyboard UI zoom: Cmd/Ctrl +/-/0 never scale the interface.
- A click outside a dialog no longer silently cancels it (Esc still does).
- With a dialog open the canvas still scrolls, pinch/Cmd-scroll zooms and
Space/middle/Hand-drag pans, like Photoshop; everything else stays modal.
- Clipboard key presses restored in raw_input_hook.
- Studio Properties card: Order::Middle (menus, popups, dialogs stay above it)
and draggable by its title off the area being worked on.
- Magic Wand options (tolerance, anti-alias, contiguous, sample all layers) in
the Studio themes too.
- egui_kittest tests: Ctrl+Plus zooms the canvas and leaves zoom_factor at 1,
zoom works with a dialog open, outside clicks keep the dialog, scroll and
space-drag pan under it.

title opens that menu. Tests for the switch and dropdown row spacing.

* PSD: read and write vibA, blnc, blwh, phfl, mixr adjustment layers
Vibrance, Color Balance, Black & White, Photo Filter and Channel Mixer
layers made in PhotoCraft were dropped on PSD save (Photoshop saw an empty
pixel layer), and the same blocks rendered as no-ops on import. They are
now parsed into their Adjustment variants and written per the Adobe spec
(descriptor blocks with version 16; phfl version 2/3; mixr version 1).
A Color Lookup without a table is written as an identity cube and a
Gradient Map with fewer than two stops as the equivalent two-stop
gradient, so every evaluated kind has an encoding.
Tests: golden hand-built blocks for each new key, malformed and fuzzed
input, and a document -> PSD -> document round trip of every adjustment
kind (8 and 16 bit, plain / masked + blended / clipped) and every blend
mode (pixel, clipped, group, pass-through, adjustment layers), asserting
model equality where lossless and composite equality within 1/255.

* Corpus: export round-trip step and pass floors; fill pixels in the mask frame
corpus.rs now re-imports every exported file and compares its flatten
with the first import (169/169 render the same). With PHOTOCRAFT_CORPUS
set (corpus dir, or 1 for the default location) it asserts the oracle
pass floor (113) and the round-trip floor (169).
The new step found gradient fills without Photoshop pixels exported in
the canvas frame instead of the frame their masks give them, so they
re-imported shifted (gradient-fill.psd/.psb, 0.26 max error). Export now
renders the fill like the compositor (render_fill_content).

- Session::execute wraps a command's run in catch_unwind: a panic that
escapes anyway becomes an EngineError ("`id` failed with an internal
error (logged); the document is unchanged"). Session::edit only commits
after its closure returns, so documents stay intact. This covers the
UI, CLI, MCP and control channels.
- apps/photocraft: a new crash_guard module installs a logging panic hook
(keeping the default one) and guards the native import/export services,
so a panic while opening or exporting a file is reported as an error
and the open documents stay. Wired in with two lines in main.rs.
- services::import_flat returns an error instead of unwrap; photocraft
and photocraft-web deny unwrap/expect/panic/unimplemented/todo/
unreachable.

- canvas: partial redraws read last_damage with unwrap_or(EMPTY), and the
GPU cache is looked up with let-else after the upload.
- icons: a missing icon (and missing fallback) yields empty bytes, which
egui shows as a broken image, instead of expect.
- type tool: the caret update is an if-let instead of expect("editing").
- Variables dialog: pages return early if their JSON state is malformed
instead of unwrap.
- parity: the same hunk as #40.
- ui-egui denies unwrap/expect/panic/unimplemented/todo/unreachable
(a one-line attribute in lib.rs).

- apply_tiled reads the shared image for a global filter instead of
unreachable! if it were missing.
- panorama: bundle-adjustment params come from the placed transforms via
filter_map; the pyramid size loop and the collapse use let-else instead
of expect.
- inpaint/pyramid: the same while-let/let-else hunks as #40, so the two
PRs merge in either order.
- quick selection's constant broad model keeps one documented narrow
expect (eight fixed corners always fit).
- algo denies unwrap/expect/panic/unimplemented/todo/unreachable.

- A failed readback mapping (e.g. device lost) now returns Unsupported,
so the caller falls back to the CPU compositor, instead of
expect("mapped readback buffer").
- Pipeline creation skips kernels without an entry point instead of
expect; resident/effect entries are looked up with let-else after the
insert; effect-program targets are Option instead of indexing +
expect; copies without a source are skipped; the planner returns
Unsupported instead of unreachable! for an adjustment layer.
- gpu denies unwrap/expect/panic/unimplemented/todo/unreachable.

Every unwrap/expect/unreachable in non-test engine code now returns an
EngineError (or a predicate's Err string) or uses a real fallback:
- enabled predicates read the active layer through active_layer_of()
instead of unwrap() after has_layer();
- new raster layers get their pixels through pixels_mut()? instead of
surface_mut().expect("raster");
- layer paths use split_last().ok_or(..)? (Merge Down, Arrange, Ungroup,
Release Clipping), Auto-Align/Auto-Blend/Photomerge carry placements
instead of re-unwrapping them, and "next free name" searches are bounded;
- web export builds its options map directly, quantize_rows has a wasm
tail, parse_script rejects non-array/object JSON, the shape-layer edit
returns an error instead of unreachable!, and the gray composite
profile falls back to sRGB.
The engine denies unwrap/expect/panic/unimplemented/todo/unreachable.

Three remaining expect() sites in files no open PR touches:
algo::inpaint::complete and algo::pyramid::gaussian loop with while-let

the menu it just pushed instead of last_mut().expect().

- rpc::respond (the JSON-lines server behind `photocraft-cli run`/TCP)
catches a panicking request and answers it with an error, and keeps
using a poisoned session lock (as the MCP server already does) instead
of failing every later call with "session lock poisoned". Regression
test poisoned_session_keeps_serving.
- MCP server: the eight bridge_client().expect("bridge") and the
headless_op(..).expect("headless") calls return a tool error instead.
- bridge: the connection is taken with let-else, not expect.
- automation and photocraft-cli deny unwrap/expect/panic/unimplemented/
todo/unreachable.

- Real crash: build_engine_data took its template from the PSD's text
engine data and did expect("EngineDict"), so a text layer whose engine
data lacked EngineDict (or wasn't a dictionary) crashed PSD export.
The template is now repaired; regression test
engine_data_template_without_engine_dict.
- color: the built-in CMYK<->sRGB transforms fall back to the naive
formulas instead of expect if they ever fail to link.
- doc: insert_above falls back to the top of the root instead of
expect("valid path"); next_layer_name searches a bounded range.
- paint: Mips::new loops with while-let instead of last().expect.
- All eight crates deny unwrap/expect/panic/unimplemented/todo/unreachable.

- Real crash: a gray ICC profile whose A2B0 tag is stored as "mBA "
parsed fine, but re-encoding its RGB view (gray_as_rgb, used for gray
documents' composites) hit panic!("unsupported lutAtoB stage layout").
The ICC writer now leaves out a LUT its tag type can't store, and
gray_as_rgb drops the gray LUTs (one input channel) so the RGB view is
the matrix/TRC model it builds. Regression test
gray_profile_with_reversed_lut_type_reencodes.
- math::rgb_to_xyz_matrix returns None for dependent primaries.
- Builtin::profile indexes its cache by discriminant (tested); the shipped
CMYK profile falls back to synth::coated_cmyk() instead of expect.
- Two constant-only expects (Bradford inverse, built-in primaries) use the
documented narrow allow.
- cms denies unwrap/expect/panic/unimplemented/todo/unreachable.

- codecs: bump tiff 0.10 -> 0.11. tiff 0.10 indexed an empty SampleFormat
list and panicked on a crafted TIFF (found by mutation fuzzing);
regression test tiff_empty_sample_format_is_an_error.
- codecs: Image::new returns Result instead of panicking on size overflow.
- format: par_compress returns an error if a compression worker panics.
- io: par_map joins every worker before relaying a worker panic, so the
thread scope can't panic on an unjoined thread.
- All four crates now deny unwrap/expect/panic/unimplemented/todo/
unreachable outside tests.

Close, Close All, Close Others, Revert, Exit and the window close button

Once Format stopped failing first, the Linux runner reached the GPU tests
for the first time: its software adapter (GL) can't render Rgba32Float or
R32Float. The app already picks Rgba16Float there, but the effect-map
pipelines (R32Float/R16Float) still panicked. They are now built inside an
error scope; where they can't be, documents with layer effects use the CPU
compositor and everything else stays on the GPU.
The exact-parity tests skip on adapters without 32-bit float targets (the
app uses the CPU compositor there), like they already skip without an
adapter; the fallback-path tests build with try_new_with_format.

On D3D12 without DXC, wgpu compiles HLSL with FXC, which aborted on
fs_adjust ("internal error: compilation aborted unexpectedly"). wgpu turns
that into a panic, so every GPU test failed on the Windows runner, and the
app would crash where the same path is taken. A bisect on the Windows
runner pinned it to two cases of adjust()'s switch, Exposure and Selective
Color: both looped over dynamically indexed vector components. They are
now written per channel / per range with the same math (GPU-vs-CPU parity
is unchanged and passes on Metal and on the Windows runner).
Compositor::try_new_with_format catches validation and internal errors
while building the pipelines and returns Err; the canvas then uses the CPU
compositor (once, remembered) instead of crashing.

Rust 1.99's clippy adds chunks_exact_to_as_chunks and some_filter, which

CI's `cargo fmt --all -- --check` has failed on every run because the

also keeps the churn small. Formatting only; no code changes.

AGENTS.md gets a prominent "Never crash" section at the top of the golden

the workspace).

The canvas only showed effects after OK. While the dialog is open, the
canvas now renders the document with the dialog's style applied: the same
commands OK runs, replayed on a scratch session (no history), cached by
document revision + style fields so switching pages doesn't re-render.
Cancel drops the preview. Works on both GPU and CPU canvas paths
(display_doc). Tests cover the preview, re-render on edit, and cancel.

All dialogs (Layer Style, New Document, filters, ...) were pinned to the

Model Blend If (This Layer / Underlying Layer ranges, split points) as
Layer::blend_if, read and write it as the PSD layer-record blending

k × alpha), fall back to the CPU on the GPU path, and drive it from
layer.layerStyle.blendingOptions {"blendIf": …}; document.inspect

Photoshop's Minimum and Maximum have Preserve: Squareness | Roundness;
only the square element existed. Roundness takes the extreme over a
disc (dx² + dy² ≤ r²), one van Herk / Gil-Werman running min/max per
disc row, so cost stays O(r) per pixel. filter.other.minimum/maximum
take "preserve" (default squareness; older params deserialize as
Squareness).

Camera raw files are TIFF-structured, so they reached the TIFF decoder.
A raw image with the TIFF/EP CFA or DNG LinearRaw photometric
interpretation failed with "Tiff: unknown photometric interpretation",
a CR2 with "colour type YCbCr(8)", and a DNG or a raw whose sensor data
sits in a SubIFD behind an RGB IFD0 quietly opened that small preview
as if it were the photo.
The TIFF decoder now checks the structure first (CR2 signature,
DNGVersion tag, CFA / LinearRaw image in IFD0, its SubIFDs or the next
IFDs; bounds-checked header reads only) and returns Unsupported:
"camera raw files (such as CR2, NEF, ARW or DNG) are not supported".
Ordinary TIFFs decode as before. Tests use tiny synthetic TIFFs with
those markers, including truncations.

On Debian/Ubuntu with colord installed, system_profiles panics on
/usr/share/color/icc/colord/x11-colors.icc ("unsupported ICC feature:
curve type \0\1\0\0"). That profile is a named-colour (nmcl) profile
whose B2A0 lutBToAType is spec-invalid: inputs=3, but the M-curve
offset (32) leaves room for one curve before the matrix offset (48),
and the 48-byte matrix overlaps the B curves at 64. The parser reads
the second M curve at offset 48 and correctly rejects it. Named-colour
profiles are never used for conversions (the test already skips them
after parsing), so skip them when they fail to parse instead of failing
the suite on a host file.

warp_gray cleared the old + warped region as one dense buffer spanning their
union, so moving a selection/mask/channel far away (e.g. dx=1e5) allocated a
~1e5x1e5 buffer and hung the app. Write the two regions separately instead —
Surface is tile-sparse, so a distant region costs only its own tiles. Found by
the panic_hunt fuzz (now also catches hangs via a per-command thread timeout).
