Roadmap

Status legend: ✅ done · 🟡 in progress · ⬜ not started. Updated 2026-09-30.

Parity metric: cargo xtask parity measures how much of Photoshop's menu tree is live and writes parity.md. It is the headline number for "how close are we", next to the PSD composite oracle and the test count.

M	Status	Where we are
M0 Skeleton	✅	workspace, xtask (layers / wasm / ci / stats / corpus / parity), CI workflow
M1 Foundation	✅	geom, color (27 blend modes), raster (COW tiles, any depth), doc, ops, cms (ICC)
M2 PSD v1	✅	photocraft-psd: 134/135 real files byte-exact round trip
M3 Viewer app	✅	egui shell (Pro / Studio / Classic themes), 13+ codecs, native and web (trunk) builds
M4 Native format + engine	✅	500+ commands, .pcraft (incremental, autosave, crash recovery), CLI, persistent preferences
M5 GPU compositor	🟡	wgpu compositor drives the canvas, layer effects included (≤1/255 vs CPU); vector masks, uncached pattern fills, artboards and a few clip cases fall back to the CPU
M6 Paint + select	🟡	brush engine, all selection tools, multi-layer selection, snapping + smart guides, free transform + warp; native tablet backends pending
M7 Adjust + filters	🟡	16 adjustment layers + destructive-only adjustments, 70+ filters incl. Blur Gallery, Actions record/replay, Fade
M8 PSD v2	🟡	adjustments (incl. Selective Color, Color Lookup), fills, effects, patterns, text, shapes, smart objects, alpha channels; oracle 111/170
M9 Text, vector, styles	🟡	type engine + Warp Text, shapes / pen / paths, all 10 effects on CPU and GPU (parity ≤1/255, 30/31 corpus effect files on the GPU)
M10 Smart features	🟡	classical Select Subject / Object, content-aware fill and scale, healing, auto-align / auto-blend; ML backend not started
M11 Automation + formats	🟡	MCP (headless + live bridge), batch, Image Processor, prefs over MCP; DoD test passes (10 agent tasks over MCP, automation/tests/agent_tasks.rs); JP2 / DICOM / DPX / C2PA pending
M12 Pro parity	🟡	CMYK / Lab / Indexed / Bitmap / Duotone, ICC + soft proofing, channels + Quick Mask, smart-object stack modes; print, HDR, photomerge, timeline, artboards, layer comps pending

Menu parity: 518 / 625 (82.9%) on 2026-10-01, up from 224 (35.8%) the day before. See parity.md.

Current focus (infrastructure before the long tail)

Landed on 2026-10-01: multi-layer selection, live smart objects + smart filters, alpha channels + Quick Mask, patterns, Warp, preferences, snapping, ~33 filters, the remaining core adjustments.

Next:

1. Fidelity: the PSD oracle (111/170). Bevel/emboss, satin, inner glow; modern Brightness/Contrast and grayscale Levels curves; channel restrictions (brst); Lab-space blending; Photoshop smart filters in SoLd.
2. Layer Comps and Artboards (File/Layer/View items and export depend on them).
3. GPU layer effects (the last big CPU fallback on the canvas).
4. Puppet Warp, Perspective Warp, Liquify, Vanishing Point, Camera Raw / Lens Correction.
5. Panels: Patterns, Styles, Glyphs, Character/Paragraph Styles, Timeline; Custom Shape tool.
6. Print, Photomerge, Merge to HDR, video layers.

Milestone definitions

Each milestone has a definition of done (DoD) and must leave main green on all Tier-1 platforms plus a wasm build.

M	Name	Scope (key items)	DoD / acceptance
M0	Skeleton	Workspace, all crate stubs, lints, xtask (layers check, ci), CI matrix, testkit	cargo test --workspace green; cargo check --target wasm32-unknown-unknown -p photocraft-engine -p photocraft-ui-egui green; layering check passes
M1	Foundation	geom, color (formats, blend math for all 27 modes, sRGB/linear), raster (sparse COW tiles, U8/U16/F32), doc (full type model incl. CMYK/Lab/adjust/smart), ops (history)	Property tests (proptest) on tile COW and history; blend-mode reference tests against published formulas
