PhotoCraft scorecard

Generated by cargo xtask scorecard from perf/budgets.toml, perf/baseline.json, crates/io/tests/it/corpus.rs, scorecard/*.toml and the source tree. Do not edit by hand: change the sources and regenerate (CI runs cargo xtask scorecard --check). Checklist statuses are verified against the code; numbers here supersede estimates elsewhere.

Performance

Budgets: perf/budgets.toml (targets from #209, #210, #211). Numbers: the committed baseline (perf/baseline.json, full run), updated only by cargo xtask perf --update-baseline. The nightly perf-nightly workflow runs cargo xtask perf on a fixed macOS runner and fails on a broken enforced budget or a p50 regression over 15 % against a baseline from the same machine class. "Over budget" rows are targets the code doesn't meet yet: they are reported, and only their regressions fail.

Baseline: 2026-10-05, commit f5d2bcb54a, Apple M4 Pro (48 GB), GPU Apple M4 Pro, macOS 15.6; load average 224.90 / 226.31 / 196.03 (1/5/15 min) at the start of the run.

FILE-215-1	Smart Objects export as embedded Smart Objects (SoLd + lnk2), not flat pixels	done	#215	psd_export.rs smart_blocks: PlLd + SoLd, source in lnk2 (.pcraft -> PSB); engine tests/it/smart_psd.rs; Photoshop 2026 opens 8/16-bit exports as live smart objects. Linked files are embedded
FILE-215-2	Smart Filters survive PSD save and re-open (filterFX descriptor read and written)	partial	#215	smart_map.rs: 41 filters plus Hue/Saturation, Perspective Warp, Filter Gallery (Chrome) and a verified Camera Raw subset mapped both ways, others kept verbatim, mask in FEid; io tests/it/smart_corpus.rs. PhotoCraft-only filters (Twirl, Liquify…) and unmapped Camera Raw settings are left out of filterFX with a warning
FILE-215-3	Filter mask can be painted directly, with undo	missing	#215	smart_cmds.rs:382 mask only from the selection
FILE-215-4	Adjustments (Hue/Sat + Colorize, Curves, Levels, Shadows/Highlights) apply as Smart Filters	done	#215	Image › Adjustments on a smart object records image.adjustments. as a smart filter (adjust_cmds.rs adjust_as_smart_filter; the selection becomes the filter mask), re-rendered from the source by adjust_as_filter and re-editable with layer.smartFilter.setParams; PSD maps Levels/Curves/Shadows-Highlights both ways (smart_map.rs). Opening the editor from the smart-filter row is FILE-215-5's row work
FILE-215-5	Smart Filter rows: collapse, mask thumb, blend icon, drag reorder, context menu, live preview	partial	#215	smart_ui.rs:31 rows + visibility + editor; no collapse, drag or context menu
FILE-215-6	Smart Object corner skew and perspective (quad or homography transform)	done	#215	#426: SmartObject.perspective holds the projective map (transform keeps its affine approximation); Distort / Perspective on a smart object set it (transform_cmds.rs, smart_cmds::set_placement), it re-renders from the source through the homography, Warp composes with it, and the PSD placement reads and writes nonAffineTransform / Trnf (io/blocks.rs placed_projective, smart_map.rs); tests distort_survives_edit_contents, warp_on_a_distorted_smart_object_follows_the_corners, placement survives the save
FILE-215-7	Layered TIFF read and write (tag 37724), honouring the ask-before-saving pref	partial	#215	psd tiff.rs (ImageSourceData, both byte orders), io tiff_layers.rs, ui tiff_options_ui.rs (Discard Layers and Save a Copy); extra alpha channels and a Quick Mask are not written (the TIFF codec holds one transparency sample)
FILE-215-8	Large and BigTIFF import with banded decode across all IFDs	done	#215	codecs tiff_ifd.rs (bounds-checked IFD chain + SubIFD walk, classic and BigTIFF, cycle-safe; tiff_info / decode_tiff_page), tiff.rs banded parallel strip/tile decode, planar 1 and 2, BigTIFF write (tiff_bigtiff or > 4 GiB); io import_tiff_page; 30 MP RGB8 Deflate 345 -> 32 ms; no page picker in the UI yet
FILE-215-9	SVG opens and places as shape layers or a vector Smart Object	done	#215	io svg.rs: paths, groups, text outlines as shape layers (gradients approximated; clip/mask/filter/pattern/image subtrees rasterised); smart_cmds.rs renders an SVG source at its placement scale

PSD WB/Light/Presence, curves, HSL, grading, sharpening/noise detail, grain and numeric vignette controls mapped with descriptor preservation. Active manual Optics and unverified vignette style keep the updated ACR 18.4 fixture opaque; PSD/.pcraft saves preserve it. HDR, remaining settings and Photoshop acceptance still open

User contour library: Contour Editor New… saves the curve under a name (layer.layerStyle.contours.new/list/delete/load/save, kept with the preferences), the picker lists user contours after the standard ones and has Load/Replace/Save Contours… (.shc).

FILE-215-18	Save for Web per-slice settings remembered; Export As remembers and offers nearest scaling	done	#215	Save for Web settings survive a restart through the remembered dialog settings in prefs.dialogs (web_cmds::remember_web_settings stores them on a complete export, never the destination; file_ui.rs open_web seeds from the session's last export, else the preferences). export_dialog seeds Export As the same way (seed_remembered: format, quality, transparency, scale, resample, metadata, TGA bits) and confirm remembers them as used. Export As › Image Size › Resample offers Photoshop's six methods (Bicubic Automatic default, Nearest Neighbor included; export_preset_cmds::RESAMPLE, unknown values are errors) for the exported copy only; also layer.exportAs resample and export presets (#5838).

FILE-215-19	Save As JPEG opens a JPEG Options dialog (quality 0-12, format options)	partial	#215	jpeg_options_ui.rs: File > Save, Save As and Save a Copy to a JPEG ask for Quality 0-12 (Low/Medium/High/Maximum) and Baseline / Baseline Optimized / Progressive before writing, starting at an opened JPEG's own quality (file_encoding) or else the Export preference; scripts pass quality/jpegFormat (file.saveAs, file.saveACopy, app.save, CLI --jpeg-format) and recorded actions replay the answer (discard_ui/tests/jpeg_tests.rs, codecs roundtrip jpeg_format_options_round_trip). Baseline Optimized fits the Huffman tables only at 4:4:4 (Gray, CMYK) or progressive: RGB is written 4:2:0, which zune-jpeg 0.5.15 decodes wrongly with fitted tables, as in Save for Web, so RGB Baseline Optimized writes the same file as Baseline. Missing: Matte, progressive Scans (3-5) and the size preview
FILE-215-20	Artboard tool with handles and + buttons, Duplicate Artboard beside, vector PDF pages	partial	#215	artboard_tool.rs: Artboard tool draws, selects, moves and resizes boards by their handles (⇧ keeps proportions), its + buttons add a board or (⌥) a copy beside the selected one (#3033); Duplicate Artboard places the copy beside (#1584); raster PDF pages only
FILE-215-21	Local libraries of colours, patterns, images and layers, as linked items or copies	missing	#215	Only preset libraries (preset_store.rs)
FILE-216-1	Every corpus fetched and enforced in CI, cached by pin	done	#216	ci.yml has a corpus job (name: corpus tests) on every PR and on main: the corpora are pinned in xtask/src/corpus_pins.rs, sha256-verified after both a cache restore and a download, and a missing corpus fails the tests. The cache key follows the pins, so it is cached by pin as this row asks (#190)
FILE-216-2	Large-file fixtures: 20 MP, 150-layer, generated 2 GB PSD and 4-5 GB PSB stress tests	done	#216	Generated at test time by psd fixtures.rs (feature testgen; never committed). io tests/it/large_files.rs: layered_20_mp_psd_opens_and_saves (5472x3648, 5 layers in 2 groups, mask, drop shadow) and layout_with_150_layers_opens_and_saves (A4 300 ppi, 150 layers in 15 groups, masks, hidden layers, closed groups, drop shadows) run in every cargo test (~2 s each); opt-in psd_just_under_2_gb_opens_and_saves (17,000 px, 2.02 GB PSD) and psb_of_4_gb_opens_and_saves (25,000 px, 4.38 GB PSB, data past 4 GiB), each opened, pixel-checked, saved and re-opened; plus large_psb.rs (2.5 GB merged image). Open times: ui-egui large_file_bench (P20, P63). The 2 GB and 4 GB files are not run in CI (6.4 GB on disk; ~12 GB of memory for the PSD test, ~25 GB for the PSB test) (#5107)
FILE-216-3	TIFF, RAW and EXR corpora read by tests; per-camera RAW coverage reported	partial	#216	EXR: corpus/exr (the OpenEXR deep test images, pinned) is read by codecs tests/it/deep_exr.rs in the CI corpus job, against the ID manifests of the upstream sidecars. corpus/tiff and corpus/raw are still copied in by hand and no test reads them; no per-camera RAW report
FILE-216-4	Exports re-open in a third-party oracle editor	missing	#216	The round trip is our export -> our import
FILE-216-5	Save-path tests: layered TIFF, PDF, SVG, ACO/ASE, .shc, Smart Filters, atomic-save failure	partial	#216	Every save path that exists is tested by saving and reading back: layered TIFF io tests/it/tiff_layers.rs (every_compression_keeps_the_layers, advanced_blending_survives_layered_tiff_in_both_byte_orders), print PDF engine print_cmds/tests.rs (print_dry_run_renders_a_pdf_and_reports_the_platform_backend decodes the image back), ACO/ASE engine swatch_cmds/tests.rs (aco_round_trip_keeps_16_bit_values_and_books, ase_round_trip_keeps_groups_floats_and_kinds), .shc psd shc.rs shc_round_trips_and_rejects_hostile_input and engine layer_style.rs contour_presets_and_custom_curves_apply_in_one_undo_step, Smart Filters engine tests/it/smart_psd.rs (smart_filters_survive_psd_in_every_colour_model), atomic-save failure format/src/atomic/tests.rs (BUG-203-6). There is no SVG writer (SVG opens only) and no Photoshop PDF save (FILE-215-10), so those have nothing to test yet; the row stays partial until they exist
FILE-216-6	30-50 end-to-end workflow acceptance tasks driven through MCP or commands	partial	#216	automation/tests/it/agent_tasks.rs, agent_tasks_extended.rs and agent_tasks_more.rs: 36 MCP tasks

TOOL-213-6	Fill dialog: contents, blend, opacity, preserve transparency; remembered; Shift+Backspace	done	#213	fill_ui.rs dialog over edit.fill (fill_cmds.rs): all contents, mode, opacity, preserve; remembered in prefs; Shift+F5 / Shift+Backspace
TOOL-213-7	Live stroke preview for every brush-based retouch tool	partial	#213	Live (canvas.rs strokes_live): Brush, Pencil, Eraser, Color Replacement, Blur, Sharpen, Smudge, Dodge, Burn, Sponge, Clone Stamp, Healing Brush, History Brush (#1026, #1040), Pattern Stamp (aligned and Impressionist) and Background Eraser (#3754); the release commits the live stroke's pixels (P32) or, for the retouch tools, the same pixels the live stroke showed (tested equal at 8 and 16 bits). Spot Healing Brush shows the area it heals as a dark overlay and heals on release, as Photoshop does. Not yet live: Mixer Brush (in PR #3627)
TOOL-213-8	Clone Source: W/H link, drawn overlay (opacity/blend/clip/auto-hide), Alt target cursor	partial	#213	Clone Source overlay drawn with opacity, inversion, circular clipping, auto-hide and the Normal/Darken/Lighten/Difference blend against the image under the brush (canvas.rs draw_clone_preview, clone_source::overlay_blend); a shaped tip (sampled bitmap, rotation, roundness) clips the overlay to its outline (brush_cursor::tip_mask, #4372); W/H link (cloneSource.set linked, panel chain button, #3298)
TOOL-213-9	Eyedropper comparison ring (new colour above, current below) while sampling	done	#213	eyedropper_ring (canvas.rs): the sampled colour on the upper arc, the foreground below, drawn for the Eyedropper and Alt-sampling while the button is held; the Precise-cursor preference keeps the crosshair
TOOL-213-10	Ctrl+Alt drag resizes brush size/hardness with an on-canvas readout	done	#213	brush_resize.rs (#297, #370): Alt+right-drag, or Control+Option-drag on macOS (Control+Alt everywhere), sets diameter horizontally and hardness vertically, circle plus Diameter/Hardness readout, one coalesced tools.setBrush, no paint or history; 9 tests there
TOOL-213-11	Editable pressure curve, global and per control	done	#213	Global: Preferences › Tools › Pressure Curve (prefs tools.pressureCurve; applied to every pen sample in ui-egui stylus.rs before any brush; editor pressure_curve_ui.rs with Linear/Soft/Hard presets). Per control: every brush Dynamic has its own curve (paint ResponseCurve, the same monotone cubic; Dynamic.curve, set by tools.setBrush, e.g. shapeDynamics.size.curve) applied to its Fade/Pressure/Tilt/Wheel/Rotation input in dynamics.rs dynamic_value; Brush Settings shows it behind each Control row's curve button (#3294)

TOOL-213-14	Tablet: no OS arrow cursor over the canvas on macOS, Windows and Linux	partial	#213	Brush tools set CursorIcon::None (canvas.rs:1259-1275); not verified per OS
TOOL-213-18	Pattern Stamp tool: sibling of Clone Stamp in the S flyout	done	#213	Tool::PatternStamp in the S group; paint.patternStamp stamps the Patterns-panel tile with Aligned and Impressionist (an approximation: it jitters each dab's tile phase, not Photoshop's smeared impressionist look); engine tests cover depths, seams, hostile input
TOOL-214-1	Select and Mask workspace: view modes, Refine Edge brush, 6 outputs	partial	#214	select.refineEdge dialog with a live preview in Photoshop's view modes: Onion Skin, Marching Ants, Overlay, On Black, On White, Black & White, On Layers, per-view Opacity, Show Edge (J), Show Original (P), F cycles, X shows the image (select_mask_view.rs, #1754); Refine Edge Brush (R, size, Expand Detection Area / Restore Original Edge, Alt swaps) paints select.refineEdge refineStrokes, estimated by colour-line matting (matting/brush.rs, #2972); outputs Selection, Layer Mask, New Layer, New Layer with Mask, New Document, New Document with Mask (#2998); no workspace layout
TOOL-214-2	Marquee: Shift square, Alt from centre, live W x H readout	done	#214	canvas.rs marquee_corners: Shift square or circle, Alt from the centre, live W x H readout beside the cursor (marquee_readout); marquee_tests.rs

TOOL-214-4	Move tool: box-select layers, Auto-Select hover outline, double-click fit, drag to a tab	partial	#214	Auto-Select hover outline (Preferences › Tools › Show Highlight on Rollover, #2834) and box-select layers from an empty spot (move_box.rs:59, layer.selectInRect, #2844) done; dragging layers with the Move tool (or from the Layers panel) onto another document's tab copies them there (layer_transfer.rs:162, layer.copyToDocument, #589/#851); double-click fit and dragging a selection's pixels to another document open
TOOL-214-5	Right-click menu during Free Transform (scale, rotate, skew, warp, flip, rotate 90/180)	done	#214	canvas_tool_menu.rs TRANSFORM_MENU: modes, Content-Aware Scale / Puppet Warp greyed, Rotate 180 / 90 CW / 90 CCW and Flip turn the open box (transform_tool::intercept, #2832)
TOOL-214-6	Puppet Warp mesh follows the object outline (constrained triangulation)	done	#214	algo/puppet.rs build_mesh: traced outline of the opaque region grown by Expansion, triangulated with a Density-spaced lattice (conforming Delaunay); separate shapes get separate meshes (#3105)
TOOL-214-7	Content-Aware Scale through the Free Transform box with a live proxy preview	done	#214	Edit > Content-Aware Scale opens a scale-only Free Transform box (cas_transform.rs) with Amount, Protect and Protect Skin Tones in the options bar; edit.contentAwareScale carves a 384 px copy in the background for the live preview, and Enter runs it with the box's size and x/y as one step (#3096)
TOOL-214-8	A measured ruler angle prefills Image Rotation > Arbitrary (0.01 deg)	done	#214	analysis_ui.rs: image.rotation.arbitrary opens seeded with the ruler angle and the direction that straightens it; arbitrary_rotation_starts_at_the_ruler_angle checks 5.7106 deg within 1e-3 and cw/ccw for three measured lines
TOOL-214-9	Crop: W x H x Resolution with units, saved crop presets, Straighten in the options bar	done	#214	Ratio dropdown and fields, Straighten (TOOL-214-21); W x H x Resolution with units, built-in size presets and Front Image (crop_size.rs, image.crop targetWidth/targetHeight/resolution, #2443); New / Delete Crop Preset save and delete crop tool presets (crop_presets.rs, tool.presets.* with tool crop, persisted with the preferences)
TOOL-214-10	Pen: Alt breaks a handle, Shift 45 deg, Ctrl direct-selects, Backspace, close-drag handle	done	#214	Ctrl/Cmd = Direct Selection and Alt = Convert Point on existing paths (direct_select.rs, #790); Backspace/Delete retracts the last point while drawing (#1466); Alt during a drag breaks the handle pair, Alt-drag turns the last anchor's outgoing handle alone, and dragging on the first anchor closes with that anchor's handles (vector_ui.rs, #3306); Shift-click puts the next anchor on the nearest 45 deg ray from the previous one and Shift-drag turns the handles to 45 deg steps, live (vector_ui.rs pen_shift_click_puts_the_next_anchor_on_a_45_degree_ray, pen_shift_drag_turns_handles_to_45_degrees_live, #3751)
TOOL-214-11	Stroke Path dialog: pick any brush-based tool, Simulate Pressure	done	#214	path.stroke tool: Brush, Pencil, Eraser and every other brush-based tool (Background Eraser, Clone/Pattern Stamp, Healing/Spot Healing Brush, History Brush, Blur, Sharpen, Smudge, Dodge, Burn, Sponge, Color Replacement, Mixer Brush: their paint.* command along the path, one step) plus simulatePressure (taper both ends); Stroke Path dialog from the Pen menu, the Paths panel menu and Alt-click on its Stroke button (#2978)

TOOL-214-16	Liquify: redo (Cmd+Shift+Z)	done	#214	liquify_ui.rs supports bounded redo through Cmd+Shift+Z and the control channel; new strokes clear redo
TOOL-213-17	Red Eye tool: click a pupil to neutralize the red reflection	done	#213	paint.redEye (redeye_cmds.rs) + Tool::RedEye in the J flyout; Pupil Size and Darken Amount; catchlights kept; a miss is an error
TOOL-214-17	Rotate View tool: drag to turn the view, Reset View, Match Rotation copies the angle	done	#214	Tool::RotateView in the Hand flyout; view.rotateView / view.resetView; Match Rotation copies views[].rotation; enhanced_controls.rotate_view_with_trackpad is read
TOOL-1649-1	Eyedropper Sample Size (Point, 3×3 … 101×101 Average), Sample layers, Show Sampling Ring	done	#1649	document.sampleColor (sample_cmds.rs): average of the square clipped to the canvas, in the document's model and depth; eyedropper_ui.rs options bar; shared with Alt-click, dialog eyedroppers and the Info panel; ui.set eyedropperSampleSize/eyedropperSample/eyedropperRing. Color Sampler tool is separate (#1046, sampler_cmds.rs)
TOOL-214-20	Crop overlay options: Rule of Thirds, Grid, Diagonal, Triangle, Golden Ratio, Golden Spiral; Auto / Always / Never Show Overlay; O cycles the overlay, Shift+O its orientation	done	#1919	crop_overlay.rs: unit-square guides shared by upright and turned frames (canvas.rs), options-bar menu, O / Shift+O ahead of the tool keys in shortcuts.rs; ToolOptions crop_overlay / crop_overlay_show / crop_overlay_orientation, ui.set cropOverlay / cropOverlayShow / cropOverlayOrientation
TOOL-214-18	Crop: drag outside the frame to rotate it (Shift 15 deg steps, angle readout); Enter rotates and crops in one step	done	#1792	image.crop angle param (image_cmds.rs: Image Rotation > Arbitrary + crop, one undo step); crop_ui.rs turns, moves and resizes the frame along its axes (Classic Mode; default mode turns the image instead, TOOL-214-23); UiState.crop_angle
TOOL-214-19	Crop: arrow keys nudge the crop box (Shift 10 px), X swaps portrait/landscape, W x H readout while drawing or resizing	done	#1919	crop_ui.rs keys/nudge/swap_orientation (ahead of the selection nudge and tools.swapColors in shortcuts.rs; X also swaps the options-bar ratio) and sizing (canvas.rs draws it with the marquee readout); turned frames included
TOOL-214-21	Crop: Straighten button in the options bar and Cmd/Ctrl-drag draw a line; the frame turns so the line ends up level (or plumb when nearer vertical), with an angle readout	done	#1919	crop_straighten.rs: one-shot options-bar button, Cmd/Ctrl held is a temporary Straighten (ui.pointer command flag); the Ruler's straighten_angle convention; the frame is fitted to the largest of its proportions inside the image (Classic Mode); a pending edit committed by Enter
TOOL-214-22	Crop gear menu: Show Cropped Area (H), Enable Crop Shield with Match Canvas / custom colour, opacity and Auto Adjust Opacity	done	#1919	crop_shield.rs: fill() resolves the shield (canvas.rs paints it around upright and turned frames), gear popup in the options bar, H ahead of the Hand key in shortcuts.rs, Custom… opens the Color Picker; ToolOptions crop_shield, ui.set cropShield. Use Classic Mode / Auto Center Preview: TOOL-214-23
TOOL-214-23	Crop: Photoshop's default mode (the image turns and moves behind an upright box, Auto Center Preview keeps a resized box's centre in place and centres a drawn one) and Use Classic Mode (P) in the gear menu	done	#1919	crop_mode.rs: the crop model (crop_rect + crop_angle) and image.crop are shared by both modes; default mode sets the view's rotation to -crop_angle while the tool shows a frame (picking the tool, in either mode, turns a Rotate View turn upright about the view centre, not restored after Enter/Esc or by P; Classic Mode keeps the camera upright with the frame drawn turned; as Photoshop 25.1), pivoting so the box stays put, moves view and frame together for drags inside and arrow keys, keeps a resized box's centre in place live (Auto Center Preview; a drawn box is centred on release, a moved one never), readout = the image's turn; gear menu order and Classic Mode greying as Photoshop 25.1; CropShield classic_mode / auto_center_preview (ui.set cropShield), P ahead of the Pen key
TOOL-1053-1	Shape stroke controls: solid/dashed/dotted, custom dash/gap/offset, caps, joins, alignment, miter limit and opacity	done	#1053	shape_stroke_ui.rs: shared staged editor, renderer samples, cached Properties canvas preview; existing shape.create/edit/info; serde tool defaults, ui.set shapeStroke; pcraft and vstk style round trips. Gradient fill UI and saved stroke libraries remain open; Line retains filled-bar geometry
TOOL-213-19	Remove tool: paint over an object (or circle it) and it is filled from its surroundings	partial	#213	paint.remove (retouch_cmds/remove.rs, background job) + Tool::Remove in the J flyout; loops close over what they enclose; fill by non-local patch completion with texture features, onion-peel start, best-patch copy and gradient-domain seam hiding (algo/nonlocal.rs, Newson et al. IPOL 2017); sparse holes in tiles (algo/remove.rs). remove_quality on 20 holes in public-domain photos: the fill keeps 0.89 of the texture it replaces (0.54 with Content-Aware Fill's completion), edge gradient 1.03 of the original's; remove_bench 24 MP: 100 px ring 120 ms, 1000 px ring 2.5 s, 3000 px line 1.7 s. Options bar: Sample All Layers, Create a new layer (the fill on a new layer above, newLayer), Remove after each stroke off (strokes collect as a tint and ↩ applies them as one strokes job, Esc drops them). Missing: generative AI mode, live preview of the result
TOOL-2259-1	Arrow-key nudges of one thing (layers, the selection outline, the Free Transform box) that follow each other are one History state, with a preference to turn it off	done	#2259	nudge_bundle.rs: a run shares one coalesce key while each nudge comes within Tools > Nudge Bundle Pause (1 s) and nothing else touched the document (an edit, Undo/Redo, a layer selection, a save end it); move_mods.rs runs layer.translate and select.transformSelection through it, transform_tool.rs folds box nudges into one session step. Tools > Bundle Arrow-Key Nudges off gives every press its own state. Selected pixels float until dropped, which is one state already; ⌥-nudges (a copy each) never join a run
TOOL-1045-1	Color Replacement tool on the toolbar	done	#1045	Tool::ColorReplacement in the Brush (B) flyout after the Mixer Brush; Mode/Sampling/Limits/Tolerance/Anti-alias options drive paint.colorReplacement with the foreground colour; live preview (LiveDab with the stroke's finishing dab), one History step; color_replacement_tests.rs

Workspace and UI

Settings that do nothing: 21 of 176 (target 0, #204). Counted by the prefs audit (xtask/src/scorecard.rs): a Preferences field counts as read when code outside the prefs model (prefs.rs except its impl Session blocks; tests excluded; the schema-driven dialog never names a field) accesses section.field, or .section and .field in the same file, or calls a section method that reads self.field. It is a heuristic lower bound: a generic name can look read when it isn't.

Unread: general.color_picker, workspace.auto_show_hidden_panels, workspace.enable_floating_document_window_docking, performance.cache_levels, performance.gpu_adapter, performance.legacy_compositing, scratch_disks.disks, units_and_rulers.column_width, units_and_rulers.gutter, plug_ins.show_extension_panels, plug_ins.allow_scripts_to_connect, plug_ins.generator_enabled, type_.text_engine, enhanced_controls.scrubby_slider_acceleration, raw_defaults.color_space, raw_defaults.bit_depth, raw_defaults.sharpen_for, raw_defaults.open_as_smart_object, raw_defaults.apply_auto_tone, integrations.allow_agent_control, integrations.control_port.

UI-217-1	Tool options, last Export As / Save for Web / Fill settings and font recents persist	partial	#217	Tool options (Preferences.toolOptions, tool_memory.rs, #2814; clamped to the options-bar ranges on restore), each painting tool's own brush (Preferences.toolBrushes + lastBrush, #6212) and the selected tool persist; Reset Tool / Reset All Tools (tool_reset.rs) clear them. Fill, Liquify, Export As (export_dialog.rs COMMAND) and Save for Web (file_ui.rs WEB_COMMAND) remember their last settings in prefs.dialogs. Missing: font recents (type.recentFonts is in the prefs audit's unused list)
UI-217-2	Window size and dock width remembered across restarts	done	#217	eframe persistence (ui.ron): persist_window for the window, egui memory for the dock panel width; window_and_panel_geometry_survive_a_restart asserts the round trip (apps/photocraft/src/main.rs; b07a2e5b, #587)
UI-217-3	File > Open starts in the last-used folder	done	#217	file_dialog.rs last_used_dir: open dialogs ask with initial_dir (the most recent file's folder) and apps services.rs passes it to rfd set_directory; open_starts_in_the_last_used_folder + last_used_dir_takes_the_most_recent_parent

UI-217-6	Document tabs: overflow list, context menu (Close/Others/All/Reveal), drag to reorder	done	#217	canvas.rs: Close/Others/All menu with unsaved prompt; Reveal reuses file.revealInFinder (engine layer_menu_cmds::reveal); the » chevron (tab_strip) lists overflow; dragging a tab reorders via document.move
UI-217-7	Command palette shows recently run commands on an empty query	done	#217	palette.rs: note_recent from menus::invoke keeps the last 8 commands (dedup, newest first); an empty query lists them via recent_hits; the_palette_records_and_replays_recent_commands_on_an_empty_query covers record -> empty query -> replay
UI-217-8	Tool-specific canvas right-click menu; right-click spelling suggestions in text fields	partial	#217	paint_mouse.rs brush picker and canvas_tool_menu.rs selection actions; text_field_menu.rs gives every text field its right-click Undo/Cut/Copy/Paste/Delete/Select All menu (#2921); other tools missing; the Type tool's edit menu starts with spelling suggestions and Add to Dictionary over a misspelled word (#4370); over committed type the Type tool opens the type layer menu (#7324); Ignore / Ignore All, suggestions in the non-editing type menu and in generic text fields are not there yet
UI-217-9	UI scale presets 100/115/125/150/200 % through zoom_factor, remembered	done	#217	prefs::UiScale offers Auto plus 75 to 300 percent (13 presets, more than the five this row lists); prefs_ui.rs display_scale resolves it (Auto follows the system scale, fractional and unscaled 4K included, #1072/#1278) and sync_display_scale applies it with ctx.set_zoom_factor. It is a preference, so it is remembered. The zoom_factor assert in input_tests.rs is about canvas zoom not scaling the interface, not about this setting
UI-217-10	Appearance: animation toggle, canvas pattern toggle per theme, start-screen recents	partial	#217	interface.enableAnimations (prefs_ui.rs sync_animations, #3273) zeroes egui animation_time and scroll animation in both styles; the Home screen lists recent files (canvas.rs home_recent, #2691); the canvas dot pattern toggle is interface.showCanvasDots (#2264, global rather than per theme); interface.showHomeRecentFiles hides the Home screen recents (#4382)
UI-217-11	Soft dark and soft light themes with picker previews; outlined knobs in light themes	done	#217	theme.rs ThemeKind has fourteen themes: the twelve earlier ones plus Soft Dark and Soft Light (low-contrast Studio-layout palettes, text at 4.5:1, selectable in Preferences with the existing theme-card previews, ui.set {theme}, Window > Theme); the light themes outline the slider knob with Tokens::knob_outline (dim text, at least 3:1 against dock, card and chrome; #7927)

Set Black/Neutral Gray/White Point eyedroppers in the Image > Adjustments > Curves dialog (adjust_dialog.rs, #873) and in a Curves adjustment layer's Properties panel (layer_picker.rs: a click on the image is one layer.setAdjustment with the eyedropper param, sampling below the layer; Esc or another tool disarms; #3110)
UI-217-16	Hue/Saturation: Saturation slider gets a hue-following colour track, Lightness a black-grey-white track	done	#217	saturation_track/lightness_track (adjust_editors.rs): grey -> the hue, recolouring as the Hue slider moves, and a fixed black -> grey -> white (#6539); saturation_track_follows_the_hue, lightness_track_is_black_grey_white_whatever_the_hue

TYPE-218-1	Type on a path: path shape, glyphs along the curve, caret follows, PSD round trip	partial	#218	TextShape::Path (doc text.rs) with glyphs placed rigidly along the curve by arc length (text warp.rs PathFrame), type.attachToPath and type.detachFromPath (#4365), .pcraft round trip; a Type tool click on the work path or the active shape layer's path starts path type at the point clicked (type.attachToPath at, path-type pointer over a path). Missing: vertical type on a path, dragging the start/flip, the caret and selection following the curve, and PSD path text (it saves as point text)
TYPE-218-2	Paragraph direction (Auto/LTR/RTL) in the panel and options bar; visual RTL caret	partial	#218	Paragraph section (Window > Paragraph and Properties) and the options bar have Auto / Left-to-right / Right-to-left buttons setting the paragraph direction through type.setStyle; the options bar's choice is also the direction new type starts with (type_tool.rs direction_items; paragraph_direction_buttons_set_and_show_the_direction, options_bar_direction_sets_selected_layers_and_new_type). Still missing: visual RTL caret (the arrow keys move in logical order), and PSD doesn't store the direction (crates/text psd.rs neither reads nor writes it, so it reopens as Auto)
TYPE-218-3	Thai/Khmer/Indic fallback fonts; golden shaping tests for complex scripts and RTL	partial	#218	Fallback fonts are covered for Thai, Khmer, Lao, Myanmar (THAI_FAMILIES, KHMER_FAMILIES, LAO_FAMILIES, MYANMAR_FAMILIES in fonts.rs; #1909, #3259), the nine Indic scripts (INDIC_FAMILIES: Nirmala UI, Kohinoor and Sangam MN, Noto Sans) and Arabic and Hebrew. Still missing: per-script golden shaping tests against reference output (only smoke tests that an installed font shapes without .notdef, plus a bidi test)
TYPE-218-4	Variable font axis sliders from the font's axes; opsz follows the point size	done	#218	One slider per axis of the style's font in the Character section (Properties and Window > Character), setting type.setStyle variations; opsz follows the type size unless set (layout.rs variation_list); a style or weight resets the wght axis (#2985). PSD does not round-trip axis values yet
TYPE-218-5	OpenType UI: Character panel buttons, Numerals and Stylistic Sets submenus	partial	#218	Type > OpenType toggles (type_extra_cmds.rs:512). Character panel (and the Properties Character section) has Photoshop's eight OpenType buttons: Standard Ligatures, Contextual Alternates, Discretionary Ligatures, Swash, Stylistic Alternates, Titling Alternates, Ordinals, Fractions, pressed while the feature is on at the selection and dispatching the type.openType.* commands (type_tool.rs opentype_row; character_panel_opentype_buttons_toggle_and_show_the_feature, #3752). Still missing: the Numerals and Stylistic Sets submenus, and greying out features the font lacks
TYPE-218-6	Manual pair kerning (Alt+arrows), optical kerning rendered, both round-trip PSD (#206)	done	#218	Alt+Left/Right at a collapsed caret kerns the pair (type_tool.rs kern_pair, 20 per step and 100 with Cmd; type_tool_alt_arrows_kern_the_pair). Optical kerning is computed from the glyph outlines in text/src/optical.rs and applied by layout.rs when the run's mode is Optical (optical_matches_photoshop, optical_kerning_tightens_open_pairs). Both modes and manual values round-trip through PSD (io/tests/it/psd_kerning.rs; the optical mode travels in Txt2, txt2_carries_optical_kerning)
TYPE-218-7	Warp Text dialog previews live and opens with the layer's current warp	done	#218	Type > Warp Text opens with the shown layer's warp, or None, never remembered values (filter_dialog.rs:503 warp_defaults; warp_text_dialog_tests.rs:80 warp_text_opens_with_the_type_layers_current_warp, :99 warp_text_opens_at_none_for_a_layer_without_warp, :108 remembered_warp_values_never_override_the_layers_warp). The dialog previews live without editing the document, Cancel leaves no step and OK is one undoable step (:138 warp_text_dialog_previews_the_warp_without_editing_the_document, :160 cancelling_warp_text_leaves_the_document_and_history_untouched, :179 confirming_warp_text_is_one_undoable_step); the reduced-proxy preview matches the full-size result (filter_dialog.rs:2150 warp_text_preview_matches_the_full_size_result_on_a_reduced_proxy)
TYPE-218-8	Text editing: select all, double/triple/quadruple-click selection, paste, with tests	done	#218	Like Photoshop, 2 clicks select the word, 3 the laid-out line (a column in vertical type), 4 the paragraph up to the hard return, 5 all text, and the next quick click starts over (#3493; type_tool.rs next_click_count, click_selection, multi_click). Tested through real canvas clicks in point, paragraph and vertical type, with paste replacing the selection and Cmd+A selecting all (type_tool_tests.rs multi_click_selects_word_line_paragraph_and_all_in_point_text, multi_click_separates_wrapped_lines_from_paragraphs, click_counts_cycle_and_restart, click_selection_without_layout_and_on_hostile_input, multi_click_without_a_session_does_nothing)
TYPE-218-9	Distort/Perspective/Warp on live type as in Photoshop (was: offer 'Rasterize and continue?'; Photoshop doesn't prompt)	done	#218	Photoshop 2026 prompts for none of these: Edit › Transform › Warp on live type stays enabled with no rasterize prompt and offers only the warp styles (the mesh can't be dragged), so the type stays editable; Distort, Perspective and the split warps are greyed. PhotoCraft does the same: Warp on type commits the layer's Warp Text in one step (transform_tool.rs enter_type_warp, warp_cmds.rs warp_type_layer, #3004; warp_on_type_takes_a_style_and_keeps_the_type_editable), Distort/Perspective greyed (enable_rules.rs, #2701)

Automation

Menu wiring (docs/parity-checklist.md): 631 of 631 menu items live (100.0%). This counts dispatch, not behaviour.

Id	Target	Status	Issue	Note
AUTO-1	Every menu item dispatches a command id (UI, CLI, control channel and MCP share them)	done		docs/parity-checklist.md: all menu items live; menus.rs is_live
AUTO-219-1	Record actions in a document-independent form (implicit layer, merged type keystrokes)	missing	#219	actions.rs:47 copies raw journal entries with explicit layer ids
AUTO-219-2	Actions panel: step and dialog toggles, reorder, delete a step, Stop, sets, .atn import	done	#219	2026-10-12: set folders (collapsible, drag between sets, actions.assignSet), dialog toggle column (playback opens the step's dialog seeded with its values and resumes on OK; actions.dialog), Insert Stop… (actions.insert), step toggles, reorder, delete a step; Load/Save Actions (.atn) in the panel menu, CLI batch and actions.load/save (atn_cmds.rs): 90 Photoshop events map to commands both ways, the rest are kept verbatim and fail at playback by name; step toggles, reorder and delete a step done; Stop steps play (actions.stopMessage) but there is no Insert Stop menu item; sets and dialog toggles are stored and round-trip but the panel neither groups by set nor edits the dialog toggle
AUTO-219-3	actions.record/stop/play/list commands for agents and the CLI	done	#219	actions.list/get/record/stop/play/delete in actions_cmds.rs; the panel, CLI and MCP share them. Nested steps pass the session authorize hook.
AUTO-219-4	Replay tests for crop, filters, selections and styled text on a second document	done	#219	actions_cmds.rs: a_recorded_edit_run_replays_on_a_second_document records a crop, a Gaussian Blur, a selection fill and faux-bold type on one document and replays all of them onto a second (plus the original layer/select/fill replay)
AUTO-219-5	Batch: subfolders, open documents, naming template, progress/cancel, error log, stop	partial	#219	file_cmds.rs and file_cmds/batch_naming.rs: folder/array input, per-file errors, {name}/{serial}/{date} output templates and starting serial, Include All Subfolders (includeSubfolders: depth/loop/file-count bounded, results keep their subfolder; Batch and Image Processor dialogs, #3753); no open-documents source, cancel or error-log file
AUTO-219-6	Plug-in ABI v2: panel kind, progress/cancel calls, read other layers, Last Filter repeats	missing	#219	runtime.rs:15 ABI_VERSION = 1; manifest.rs:18 Kind::Filter only

AUTO-219-8	xtask check that every panel button routes through a command id	missing	#219	No such xtask check
AUTO-219-9	Headless commands for in-canvas type editing, Liquify/Puppet strokes, transform handles	done	#219	type.hitTest, type.caret, type.navigate; filter.liquify strokes, edit.puppetWarp pins, type.edit, edit.transform
AUTO-219-10	Agent acceptance suite grown to 30-50 workflows	partial	#219	automation/tests/it/agent_tasks.rs runs 10 workflows over MCP

Reliability

Never-crash attribute on 30 of 30 crate roots.

Id	Target	Status	Issue	Note
REL-1	panic_hunt fuzzes every command with adversarial params	done		engine/tests/panic_hunt.rs: every command, own thread, 4 s timeout; #[ignore], run in the gate
REL-2	Every workspace crate carries the never-crash deny(clippy::unwrap_used, ...) attribute	done		Counted automatically above (crate roots under crates/ and apps/); testkit gained it in #221
REL-3	The app catches escaped panics around command dispatch and import/export	done		a_panic_in_a_command_... runs the test-only test.panic spec through Session::execute and asserts Err plus an unchanged document (engine jobs_tests.rs); the worker guard is covered by a_panic_in_the_worker_...; crash_guard.rs guard_turns_a_panic_into_an_error covers import/export (apps/photocraft)
REL-4	Atomic save (temp, fsync, rename) for every document write	done	#203	photocraft_format::atomic_write (format/src/atomic.rs, #230): same-dir temp, sync_all, rename with Windows PermissionDenied retry, Unix dir fsync; every document write site routes through it and format/src/atomic/tests.rs failure-injects write, rename and read-only-dir errors
REL-212-1	Fallible allocation for paste/erase/fill/transform/save/import, clear out-of-memory error	partial	#212	Raster region/tile buffers, paste/erase/fill/transform and warp output use fallible reservations; save/import boundaries preserve existing state, but encoder/decoder internals still need a broader fallible-allocation audit
REL-212-2	Export switches to PSB when the estimated file size exceeds 2 GB	done	#212	PSD export uses checked size estimates for raster, masks, channels, and retained metadata
REL-212-3	Tests: an allocation-limit injection makes each command Err with the document unchanged	partial	#212	Engine failpoint tests cover paste, erase, fill, transform, import and save transaction boundaries; codec-level allocator failure coverage remains open

BUG-203-1	Every document write goes through one atomic_write (temp, fsync, rename)	done	#203	photocraft_format::atomic_write (format/src/atomic.rs, #230/8227071); every write site routes through it: engine file_cmds.rs write_file and preset_store.rs, automation files.rs/headless.rs/workspace.rs, app services.rs write_atomic, format store.rs and autosave.rs
BUG-203-2	Temp file in the same dir, sync_all, rename over target, fsync dir on Unix	done	#203	atomic.rs: temp_name in the same dir, create_new + write_all + sync_all, Unix directory fsync after the rename
BUG-203-3	Windows: retry the rename with backoff on PermissionDenied	done	#203	atomic.rs RenameRetry::platform(): seven retries from 10 ms on Windows; retry_rename is shared with automation's cap-std workspace write
BUG-203-4	Unwritable directory errors clearly, never falls back to writing in place	done	#203	atomic.rs maps read-only dir, disk-full and cross-device rename errors to messages that say the original was not changed; there is no in-place fallback path
BUG-203-5	On any failure the original file is untouched and the temp file removed	done	#203	atomic.rs removes the temp file on every failure; tests assert the original bytes survive write and rename failures
BUG-203-6	Failure-injection tests: mid-write, rename and read-only dir errors keep original bytes	done	#203	format/src/atomic/tests.rs: Faulty AtomicFs injects mid-write StorageFull, rename failure and a read-only dir; locked-target retries, symlink and file-mode preservation covered too
BUG-204-1	Interface prefs (UI scale, font size, channels in colour, sliders, tooltips) wired or hidden	done	#204	prefs_ui.rs tick reads ui_scale (sync_display_scale), ui_font_size (theme::set_ui_font_size) and show_tooltips (sync_tooltips); show_channels_in_color is wired in channel_thumbs and the canvas channel view (#2385); dynamic_color_sliders is in prefs::HIDDEN_UNTIL_IMPLEMENTED
BUG-204-2	workspace.large_tabs, animated_zoom, auto_show_home_screen wired or hidden	done	#204	workspace.large_tabs controls document tab height in canvas.rs; auto_show_home_screen drives the Home screen; general.animated_zoom gates discrete canvas zoom transitions and continuous held Zoom tool presses (zoom_hold.rs, #6210), and is exposed in General preferences

BUG-205-5	Tests: linked mask + selection stays aligned; unlinked stays; targeted mask only	done	#205	All three in transform_cmds.rs: linked_mask_with_a_selection_moves_only_the_selected_region checks the mask value under each moved pixel, unlinked_mask_stays_put covers it with and without a selection, targeted_unlinked_mask_transforms_alone moves the mask while the layer bounds stay
BUG-206-1	CharStyle models per-character manual kerning separately from the auto-kern mode	done	#206	doc/src/text.rs CharStyle carries both: kerning: Kerning for the automatic mode (Metrics/Optical/Off) and kern: f32 for manual kerning in 1/1000 em between this character and the next, added on top of the pair's automatic kerning
BUG-206-2	PSD import keeps Optical and manual Kerning values	done	#206	io/tests/it/psd_kerning.rs manual_and_off_kerning_round_trip_through_psd and optical_kerning_round_trips_through_psd import an exported layer and compare every character's (mode, kern) pair; the optical mode travels in the document Txt2 block (#1348)
