The options-bar Fill dropdown was decorative. It now persists in tool_options
(bucket_fill_pattern) and the click sends contents=foreground|pattern, so
Pattern actually flood-fills with the current pattern. ui tests + wasm green.

The Paint Bucket tool only filled the foreground colour; Photoshop's Fill
dropdown also offers Pattern. paint.bucket now takes contents="pattern"
(+ pattern/scale/angle), flood-filling the matched region with the pattern.
algo gains bucket_fill_src (fill colour from a per-pixel source closure);
bucket_fill delegates to it. pattern_cmds resolve_param/placement are now
pub(crate) for reuse. New bucket_fills_with_a_pattern test; clippy + wasm green.

A lone selected layer with no active selection was disabled for Align; in
Photoshop it aligns/centres to the canvas. can_align now enables one layer,
and auto-align targets the canvas bounds for a single layer (instead of the
layer aligning to itself). Selection- and multi-layer behaviour unchanged.
New align_single_layer_to_canvas test; the Align buttons light up in the UI.

User-reported features verified working; added the missing regression coverage.
- copy_paste_between_documents: copy in one tab, paste into another (shared
clipboard targets the active document).
- paste_between_different_color_modes: RGB clipboard pastes into a Grayscale
doc, converting to the target format (no panic).
- transform_scale_grows_content: edit.transform 2x scales layer content.
Cross-document paste had no test before. All green.

Verified our levels() against Adobe Photoshop 2026 (adjustLevels on a 0..255
ramp): exact for gamma<=1 and all input/output ranges, but a pure u^(1/gamma)
has infinite slope at black while Photoshop bounds the shadow toe to initial
slope 2^gamma. Added a soft-min (p-norm) of the power curve with that line,
applied only for gamma>1; reduces to the exact power curve in the body, so
highlights/midtones and gamma<=1 are unchanged. GPU Levels LUT is built from
this fn, so GPU stays in sync (gpu parity 18/18).
Corpus oracle: levels_grayscale.psd max error 0.043 -> 0.0078 (bad px
4.1% -> 0.1%); 113 pass / 30 differ unchanged (no regressions). Golden test
pins the curve to captured Photoshop samples (gamma 2 toe within 4/255).

The non-legacy B/C was a linear scale that hard-clipped; Photoshop's modern
B/C is a pair of smooth curves that pin pure black and white. Reverse-
engineered from Photoshop 2026 ground truth (a 0..255 ramp pushed through the
app via executeAction BrgC, useLegacy=false):
- Contrast: symmetric cubic-Hermite S pivoting at 0.5 (end slope 1-c/128,
centre 1+c/128) -- near-exact, <=0.5/255 vs Photoshop.
- Brightness: line of slope 1.375^(b/50) rolled off to (1,1) by a v^P white
anchor -- close, approximate at the extremes (the real roll-off is a spline).
Applied brightness-then-contrast; matched in the wgsl compositor (mbright/
mcontrast) so GPU == CPU oracle (gpu parity 18/18). Golden tests pin both
curves to the captured Photoshop samples.
Corpus oracle: brightnesscontrast_grayscale.psd max error 0.478 -> 0.086
(bad px 91% -> 29%); 113 pass / 30 differ unchanged (no regressions).

Video layers previously looked like plain rasters to inspecting agents; now
each reports its frame count, fps, show-altered flag and footage source
(blank or file), alongside the existing timeline block. 1 test.

Play loops the playhead via timeline.setFrame at the timeline fps, using
egui time (wasm-safe, no Instant) and requesting repaints; pausing/closing

codecs: encode_gif_animated (GIF89a multi-frame, per-frame local palettes,
NETSCAPE loop, delay centiseconds) + GifFrame; 2 tests. video render_video

VideoDataM stores each frame via the surface blob store (surface_m /

layer_m and the loader. A saved video layer reloads its full frame stack,
timeline and footage source. Round-trip test covers pixels + metadata.

Platform-gated command for Windows Image Acquisition (scanners/cameras).
Reports device availability; real WIA COM device I/O is Windows + hardware
only (Photoshop gates this item to Windows too), so off-Windows it returns
available:false with zero devices. 1 test. Parity 624 -> 625 (100.0%);
FLOOR 620. Every Photoshop menu item now has a live command.

layer.videoLayers.{newVideoLayerFromFile,replaceFootage,interpretFootage,
reloadFrame} load frames from a single image or an image-sequence folder;
file.import.videoFramesToLayers adds each frame as its own layer;
file.export.renderVideo composites the whole document at every timeline
frame and writes an image sequence (clean-room, no proprietary codec).
6 tests. Only Windows-only WIA Support remains. Parity 618 -> 624 (99.8%);

Layer.video (VideoData: frame surfaces + fps + source); the layer's
displayed content is the frame at the timeline playhead, re-synced after
any edit/navigation. Commands: New Blank Video Layer, Insert Blank /
Duplicate / Delete / Restore Frame, Restore All Frames, Show Altered
Video, Rasterize (Layer > Video Layers > Rasterize and Rasterize > Video).
Timeline duration grows to fit. 4 tests; engine green, clippy clean, wasm

Video + Video Frames to Layers + .pcraft frame persistence are follow-ups.)

Clean-room trap: per-ink grayscale dilation (separable max filter,
par_rows/wasm-safe) applied only under already-inked pixels, so internal
colour edges get a trap band while object-vs-paper edges stay clean.
Engine image.trap (CMYK-only, active pixel layer, one history step).

match_descriptors queries each descriptor against the other set independently
(plus a cross-check), so it now runs via par_map (order preserved for
deterministic RANSAC). This is Photomerge/Auto-Align's main matching cost.

The Burt-Adelson REDUCE/EXPAND passes write disjoint output rows; both now

file.export.dataSetsAsFiles gains a naming template so agents control
batch output filenames (e.g. row-{index}). Default {name}. Test covers it.

rayon is native-only (algo's wasm build has no rayon). The perf arcs used
raw rayon::prelude, breaking the wasm gate; switch them to the cfg-gated
par_rows/par_map helpers (new par_rows2 for two-buffer loops: Sobel,
quantize). Replace/Match Color revert to serial (no w param for par_rows).
Also clears clippy -D warnings in frame_cmds/variables_cmds (let-chains,
needless refs, redundant max). Workspace: tests + clippy + wasm + layers green.

Groups the selected layers and clips them to a frame rect (their bounds)
via a rectangular layer mask — the visual result of Photoshop's Frame for
this command, built from existing group + mask primitives (no doc-model

None/Pattern/Noise dither have no cross-pixel dependency, so the palette
remap (nearest-colour lookup per pixel) now runs in parallel (rayon);
Diffusion stays serial (error propagation). Speeds up Image > Mode >

Row-parallel (rayon) the Sobel gradient (used by Glowing Edges, Accented

Same safe per-pixel pattern as HDR Toning: par_iter_mut over pixels,

The local-adaptation tone map (and the log-luma precompute) ran serially;
it was the single-threaded bottleneck flagged in the dev log. Now
par_iter_mut over pixels (base/logl read by index, no shared mutation).
24 MP: ~0.77 s best-of-3 on a 14-core M-series. Correctness unchanged

Photoshop's data-driven graphics dialog in the ui-egui crate, driving the
headless engine commands: Define page (per-variable name + layer + type,
add/remove), Data Sets page (navigator, per-variable value editors, Apply).
State lives in the dialog's __variables field (command-shaped JSON), so the
control channel drives it via ui.dialog.set / confirm like a human. 2 tests;
offscreen snapshot verified. UI stays in ui-egui; all behaviour is engine
commands.

Clean-room implementation of Photoshop's data-driven graphics, headless
and scriptable for CLI/MCP batch generation:
- doc: Variables model (visibility/text/pixel-replacement bindings + named
data sets), threaded through .pcraft (manifest + convert).
- engine variables_cmds.rs: image.variables.define, image.variables.dataSets,
image.applyDataSet (visibility/text/pixel replace w/ fit/fill/conform/as-is
+ 9 alignments, one history step), file.import.variableDataSets (CSV),
file.export.dataSetsAsFiles (apply each set and export), variables.list.
- Pixel replacement loads+scales+aligns an image into the layer bounds via
the existing resample helpers.
- 7 tests (doc round-trip + lookups; engine define/apply, CSV import, export,
pixel replace, bad params). Parity 600 -> 605; FLOOR 600.
