## Start every session here
1. Read the [honest assessment in `ROADMAP.md`](ROADMAP.md#honest-assessment-2026-10-05): where we stand by dimension, **where we're lacking** (the prioritized gap list) and **where we're going**. Unless the user gives you a task, pick work from that list.
2. Read `plan/STATUS.md` (local session notes, may lag the ROADMAP), then the task in `plan/execution-plan.md` §3 and the relevant `plan/architecture.md` section. Behaviour reference: `plan/illustrator/*.md`.
2. Read `plan/STATUS.md` (local session notes, may lag the ROADMAP), then the task in `plan/execution-plan.md` §3 and the relevant `plan/architecture.md` section. Behaviour reference: public documentation only (see Clean-room below); `plan/illustrator/*.md` holds notes from it.
3. Follow the autonomous operation protocol (`plan/execution-plan.md` §7): orient → plan → implement + test → verify → record → commit. Don't stop to ask unless §7 lists the decision as the user's.
`plan/` is gitignored (local only).
## Non-negotiables
- **Clean-room.** Never read, disassemble or copy anything inside the Illustrator bundle (names/listings only). Never copy Adobe icons, artwork, presets or wording beyond feature names. Behaviour comes from public docs and black-box observation of the running app with synthetic documents only (screenshots by window id, stored under `plan/illustrator/screenshots/`, never committed). Never copy GPL/AGPL code (Inkscape, lib2geom…).
- **Clean-room: never use Adobe software (absolute rule, from the project owner).** Adobe's Terms of Use forbid reverse engineering, including observing a program's inputs and outputs to recreate it. So:
- Never launch, run, script, automate (COM, AppleScript, ExtendScript, UI automation), screenshot or measure Illustrator or any other Adobe application, and never compare our output against one. Don't make test files with them, not even "synthetic" ones.
- Never read, disassemble or copy anything inside an Adobe install (binaries, plug-ins, presets, procsets, resources, help files, fonts, ICC profiles).
- Never copy Adobe-authored code or text into this repo, tests included: no PostScript procsets or prologs (AGM, CoolType, the Illustrator prologs), no sample files. Write test inputs from scratch from the public specifications (PostScript Language Reference, PDF / ISO 32000, TIFF, EPSF/DCS).
- Behaviour comes only from public documentation (helpx, published specs, public forum posts), cited by URL, and from files users send us that they own (used locally, never committed). Never copy Adobe icons, artwork, presets or wording beyond feature names.
- If a task seems to need any of this, stop and say so instead. `cargo xtask cleanroom` (run by `cargo xtask ci`) fails on Adobe copyright notices and on fixtures made with Adobe applications.
- Never copy GPL/AGPL code (Inkscape, lib2geom…).
- **Assets: no Adobe iconography or images — ever (absolute rule, from the project owner).**
- Never add, copy, trace, redraw-from, embed or ship any icon, image, artwork, cursor, preset, swatch/brush/symbol/pattern/style library, ICC profile or screenshot from Adobe products or from any other source whose licence doesn't allow it.
- Every image, icon, font or other asset must be one of:

- `cargo run --release -p vectorcraft -- --control 7979 [file.svg|file.vectorcraft]` (sibling apps' agents use the same default port: if the log says it failed to bind, pick another port — otherwise your requests reach a different app).
- Drive it: JSON lines on `127.0.0.1:7979`, e.g. `{"id":1,"method":"engine.execute","params":{"command":"shape.rectangle","params":{"x":10,"y":10,"width":100,"height":50}}}` then `{"id":2,"method":"ui.screenshot","params":{"path":"/tmp/shot.png"}}`. Methods: `crates/ui-egui/src/control.rs`.
- **For UI work, look at the result** (take `ui.screenshot`, read the PNG) and compare with `plan/illustrator/02-ui-ux.md` / `10-observed-ui.md`. `ui.screenshot` needs a presented frame: if it errors (screen locked), check the art with `ui.render` / `vectorcraft-cli run … --export x.png`, and cover panels with a headless egui frame test (see `panels/transparency.rs` tests).

- **Performance:** `vectorcraft-cli perf` checks the budgets (render/pan/zoom, hit test, save/open, SVG, Pathfinder) on a synthetic 50k-path document; `vectorcraft-cli bench FILE` times one file. Run them before and after renderer, format or geometry changes, on an idle machine (the report warns when the load average makes timings noise).
- MCP: `vectorcraft-cli mcp` (see `docs/mcp.md`).
- Shell gotcha: `mv`/`cp` are aliased interactive here — use `/bin/mv -f` / `/bin/cp -f`.

## Roadmap
`ROADMAP.md` (committed) is the shared picture of where VectorCraft stands. It holds status, the honest assessment (by dimension, the gap list, the direction), milestones, the parity table and time-to-parity estimates.
- When a task lands, update it in the same PR: the milestone row, the parity-table row (score, missing items, hours), "Shipped so far", and the gap list if the gap closed or shrank.
- Grade by behaviour against `plan/illustrator/`, not by whether a menu item exists. Scores are self-assessed, so err low.
- Grade by behaviour against the public documentation (`plan/illustrator/` notes), not by whether a menu item exists. Scores are self-assessed, so err low.
- Keep the README's Status section in step with the ROADMAP headline.

On machines with two graphics processors, VectorCraft renders on the power-saving (integrated) one by default on
Windows and macOS, and on the one the desktop runs on under Linux. To choose, use **Preferences › Performance ›

next one. To pick one when starting the app, set `WGPU_POWER_PREF=high` (or `low`), or `WGPU_ADAPTER_NAME` to part of
its name, such as `WGPU_ADAPTER_NAME=nvidia` (see [`docs/development.md`](docs/development.md#desktop-graphics-processor)).

//!
//! The canvas is rasterized on the CPU; the GPU only composites it and draws the UI, so any
//! adapter that can present to the window will do. [`adapter_order`] ranks the adapters: those that
//! can't present to the window's surface never, then the one `WGPU_ADAPTER_NAME` names, hardware
//! before software, the native backends (Vulkan, Metal, DX12) before OpenGL, and the power
//! preference ([`power_preference`]) among the rest. eframe is handed [`selector`], which takes
//! the first of that order.
//!
//! An adapter can report that it presents to the window and still fail once it does: on a hybrid
//! Linux desktop under Wayland, the compositor runs on one GPU and may refuse the frame buffers
//! another GPU allocates, which kills the window's Wayland connection; egui-wgpu then panics while
//! configuring the surface (#502). Nothing in the process can show a window after that, so when
//! the graphics fail while the window is starting up, [`finish`] starts the app again without
//! that adapter, as the next one in the order would be tried. Each restart leaves out one more
//! adapter, so it ends when none is left.

//! Floating panels: panels dragged out of the dock float inside the window as groups of tabs.
//!
//! A dock tab, an icon of the icon column or a popped-out panel's title dragged out of the dock
//! floats that panel; the strip right of the dock's tabs floats the whole tabbed group. A floating
//! group moves by its title bar (or the strip right of its tabs, or the tab of a lone panel), and a
//! tab dragged out of a group floats on its own. Dropped on the dock, which lights up while the
//! pointer is over it, a group's panels go back to where they live in the dock (the tabbed group or
//! the icon column); dropped on another group's title bar or tabs, they stack with that group. The
//! × of a group puts its panels back in the dock too. The Tools panel floats the same way by its
//! title bar ([`crate::toolbar`]) and docks again on the window's left edge.
//!
//! `window.panel.float` / `window.panel.dock` do the same for agents. The groups and the Tools
//! panel's position are kept with the preferences and in user workspaces, and a position saved on
//! a bigger window is clamped into this one when drawn.

@ -36,10 +36,19 @@ How the web shell (`apps/vectorcraft-web/src/web.rs`) differs from desktop:
## Desktop graphics processor
The canvas is rasterized on the CPU (`vectorcraft-render`, vello_cpu); the GPU (wgpu, through eframe) only composites the canvas texture and draws the UI. The desktop app (`apps/vectorcraft/src/main.rs`) therefore asks wgpu for the **power-saving** adapter by default, which is the integrated GPU on hybrid-graphics laptops. Presenting frames rendered on a discrete GPU through the integrated one made the window flicker on some laptops (#306). A machine with one GPU gets that GPU either way.
The canvas is rasterized on the CPU (`vectorcraft-render`, vello_cpu); the GPU (wgpu, through eframe) only composites the canvas texture and draws the UI, so any GPU that can show the window will do. The desktop app picks the window's adapter itself (`apps/vectorcraft/src/gpu.rs`, eframe's `native_adapter_selector`) and logs every adapter it found and the one it uses.
- **Preferences › Performance › Graphics Processor** (`gpuPreference`: `powerSaving` or `highPerformance`) picks the other one. The adapter is chosen when the window opens, so a change applies after a restart.
- The `WGPU_POWER_PREF` environment variable (`low`, `high` or `none`) overrides the preference.
- **Order:** adapters that report they can't present to the window are never tried; then the one `WGPU_ADAPTER_NAME` names; hardware before software (llvmpipe, WARP); the native backends (Vulkan, Metal, DX12) before OpenGL; then the power preference, keeping the system's order among equals.
- **Preferences › Performance › Graphics Processor** (`gpuPreference`): `automatic` (the default), `lowPower` (Power Saving, the integrated GPU) or `highPerformance` (the discrete GPU). The adapter is chosen when the window opens, so a change applies after a restart.
- **Automatic on Windows and macOS** is power saving: the system shows frames from any GPU, and presenting frames rendered on a discrete GPU through the integrated one made the window flicker on some hybrid laptops (#306).
- **Automatic on Linux and the BSDs** keeps the system's order: Mesa's Vulkan device-select layer puts the GPU the desktop runs on first (the integrated one on hybrid laptops; `DRI_PRIME` and `MESA_VK_DEVICE_SELECT` steer it). A Wayland compositor may not accept frames from another GPU: on a desktop whose compositor ran on an NVIDIA GPU, rendering on the Ryzen's integrated GPU made KWin end the window's connection ("importing the supplied dmabufs failed") and 0.5.0 crashed at startup (#502).
- 0.5.0 saved `powerSaving`, its default, for everyone; it reads as `automatic`.
- **If the window fails on its adapter while starting up** (an error from wgpu, or a panic inside wgpu or egui-wgpu during the first frames), the app starts again without that adapter and tries the next one, telling which in the status bar; the run that failed keeps its log as `vectorcraft.1.log`. On Unix the new app replaces the process (an AppImage stays mounted); on Windows it starts beside it. The adapters left out travel in `VECTORCRAFT_GPU_SKIP` (`backend:vendor:device`, such as `Vulkan:1002:164e`), one more on each restart, so the restarts end. When no adapter is left, the app logs why and exits with an error instead of panicking.
- **Environment variables** for when the choice still goes wrong, all read at startup and stronger than the preference:
- `WGPU_POWER_PREF`: `low`, `high` or `none` (the system's order).
- `WGPU_ADAPTER_NAME`: part of an adapter's name, any case (`WGPU_ADAPTER_NAME=nvidia`, `=radv`, `=intel`); the names are in the log.
- `WGPU_BACKEND`: the backends to use, such as `vulkan`, `dx12`, `metal` or `gl`.
- On Linux with Mesa, `MESA_VK_DEVICE_SELECT=10de:2f04!` (vendor:device as `vulkaninfo --summary` or `lspci -nn` show it) leaves only that GPU to Vulkan, and `DRI_PRIME=1` picks the other GPU.
- Help › About and the control channel's `ui.inspect` (`graphicsAdapter`) show the adapter in use, and the app logs it at startup.

## Linux: Wayland and X11
The window runs natively on Wayland (eframe's `wayland` feature) and on X11. The system clipboard (`apps/vectorcraft/src/clipboard.rs`) is arboard with its `wayland-data-control` feature:
The window runs natively on Wayland (eframe's `wayland` feature) and on X11. On machines with two GPUs it renders on the one the desktop runs on unless Preferences say otherwise; see [Desktop graphics processor](#desktop-graphics-processor) (#502). The system clipboard (`apps/vectorcraft/src/clipboard.rs`) is arboard with its `wayland-data-control` feature:
- **Clipboard:** under Wayland arboard talks to the compositor through the data-control protocol (wlroots compositors such as Sway and Hyprland, KDE Plasma), so bitmaps (`image/png`), SVG markup and text copied in any app paste (#398). Where the compositor lacks the protocol (GNOME's Mutter, [arboard#223](https://github.com/1Password/arboard/issues/223)), arboard falls back to the X11 clipboard through XWayland, which only holds what X11 apps copied. egui's own text paste into fields goes through smithay-clipboard and works either way.
- **Clipboard owners that never answer (#510):** reading the clipboard waits on the app that owns it: arboard gives up on an X11 owner after 4 s, and a Wayland read waits for the owner to send its data. So on Linux the check that enables the Paste menu items runs on a background thread with a second clipboard handle (`crates/ui-egui/src/clipboard_probe.rs`, installed as `Services::clipboard_probe`), only while nothing is copied in the app and a document is open, and the window keeps drawing. A paste itself still reads on the UI thread, so pasting from such an owner waits for it once. Windows and macOS keep the check on the UI thread: Windows only asks which formats the clipboard holds, macOS asks the pasteboard server.
- **Copied files:** files copied in a file manager (`text/uri-list`; `CF_HDROP` on Windows, file URLs on macOS) paste as the first one that is art (SVG, PDF, EMF/WMF or a bitmap), before the clipboard's other formats (which include the files' paths as text).
- **Dropping files on the window does not work under Wayland:** winit 0.30, which eframe 0.36 runs on, has no Wayland drag and drop ([winit#1881](https://github.com/rust-windowing/winit/issues/1881), added in winit 0.31; [egui#1563](https://github.com/emilk/egui/issues/1563)), so no `dropped_files` arrive. Until eframe moves to winit 0.31: copy the files in the file manager and paste them, use File › Place or Open, or run the app under XWayland, where drops work (`WAYLAND_DISPLAY= vectorcraft`).
- **Pens and pen displays under Wayland (#491):** winit 0.30 doesn't bind the Wayland tablet protocol (`zwp_tablet_v2`; tablet input arrives in winit 0.31, [winit#4318](https://github.com/rust-windowing/winit/pull/4318), [egui#7731](https://github.com/emilk/egui/pull/7731)). Since Plasma 6.3, KWin no longer turns tablet input into pointer input for such apps ([kwin!6336](https://invent.kde.org/plasma/kwin/-/merge_requests/6336)): the pen moves the compositor's cursor over the window, but the app gets no motion or presses and shows none of its own cursors. Until eframe moves to winit 0.31, either run the app under XWayland, which supports the tablet protocol and hands the pen to X11 apps as a pointer (`WAYLAND_DISPLAY= vectorcraft`, or `env -u WAYLAND_DISPLAY vectorcraft`; for a desktop launcher, put `env WAYLAND_DISPLAY=` before the command in its `Exec=` line), or turn KWin's deprecated emulation back on for the whole session by setting `KWIN_WAYLAND_EMULATE_TABLET=1` in KWin's environment (for example in a file under `~/.config/environment.d/` or in `/etc/environment`) and logging in again. The pen then works as a mouse, without pressure: winit 0.30 reads pen pressure on Windows only (Windows Ink, which reaches the Liquify tools' Use Pressure Pen). Other compositors that don't emulate a pointer for tablets behave the same way.

(`flatpak install --user vectorcraft-<v>-linux-<arch>.flatpak`), then install it and run
`vectorcraft-cli --version` in the sandbox. No Rust build happens there, so the bundle carries the
same binaries as the AppImage. `packaging/linux/flatpak/ai.storyteller.vectorcraft.yml` is the
