+# Guidance for coding agents
+
+PaperCraft is a native Rust design and whiteboard canvas (egui, wgpu, winit) that AI agents drive
+over MCP and a CLI. Read [CONTRIBUTING.md](CONTRIBUTING.md) and [RULES.md](RULES.md) first; this
+file is the short version for agents, and [AI_POLICY.md](AI_POLICY.md) says what the person using
+you is accountable for.
+
+## Commands
+
+```sh
+cargo build --release
+cargo fmt --all
+cargo clippy --all-targets
+cargo test --test incremental                   # only the targets your change touches
+cargo test --lib editor::changes                # unit tests of one module
+cargo check --lib --target wasm32-unknown-unknown
+```
+
+Do not run the full suite locally: it builds dozens of test binaries. It runs on GitHub before
+each release (`.github/workflows/test.yml`). `tests/update.rs` cannot run on Windows outside CI
+(it needs elevation); that failure is known.
+
+Builds run on the person's own machine, so mind its resources (RULES.md, "The machine you build
+on"): check free memory and running builds first, cap jobs at no more than half the cores
+(`cargo test -j 8 -- --test-threads=8` on 16 cores), run at low priority, run one heavy job at a
+time, and stop at once if they say it is slow.
+
+## Running the app safely
+
+Never run a test copy against the person's real projects or MCP port, and never close or restart
+their running PaperCraft. Give yours its own folder and port, and keep its PID so you can stop only
+your own process:
+
+```sh
+PAPERCRAFT_HOME=/tmp/pc PAPERCRAFT_MCP_PORT=29998 ./target/release/papercraft
+```
+
+Do not stop processes by name.
+
+## Layout
+
+`src/model` (document), `src/editor` (tools and edits), `src/render` (wgpu), `src/mcp` (tools,
+HTML/CSS mapping, lint), `src/ui` (egui panels), `src/io` (import and export), `src/project`
+(store and formats), `tests/` (scenario tests), `specs/` (feature specs), `skills/` (agent
+skills). The README's project layout lists the rest.
+
+## Conventions
+
+* Tests first; match the style of the tests next to yours, and check the behaviour is not already
+  covered.
+* Changes to the document go through `Editor::edit`: one transaction, one undo step.
+* Handle errors; do not `unwrap` user data and do not discard errors with `let _ =`.
+* Comments explain *why*, never summarise the code. No dead code, debug prints or
+  commented-out blocks.
+* Files stay under about 800 lines; split by feature.
+* Reuse the shared UI kit and theme instead of one-off values. Nothing may overflow its container.
+* Writes to projects are atomic and format changes ship a migration (see RULES.md, "Data safety").
+* Adding or removing an MCP tool means a test in `tests/mcp.rs`, a precise description, and the
+  tool count updated in the README and ROADMAP.
+* Commits are conventional (`feat(scope): summary`) and focused. Do not commit, push or tag unless
+  the person asked you to.
+
+## Designing with PaperCraft (skills, examples, screenshots)
+
+* Themes are modes, never copies: one artboard per screen, a value per mode on each variable, and
+  `set_variable_mode` to switch. Never duplicate artboards for light and dark.
+* Every colour on a themed screen is a variable.
+* Check each artboard for overflow, programmatically and by screenshot in each mode, and run
+  `lint_design`.
+* Release design locks when you finish.
+
+## Avoid
+
+* Creative additions nobody asked for; stay inside the task.
+* Trivial tests, wide or optional types added to appease the compiler, and swallowed errors.
+* Editing generated files, lockfiles or release artifacts by hand, or touching files unrelated to
+  the task. Leave other people's uncommitted work alone.

+# AI usage policy
+
+PaperCraft is built to be driven by AI agents, and many of its contributors use them too. AI tools
+are welcome here. What we ask is that a person stays accountable for everything submitted.
+
+## For contributors
+
+* **You own what you submit.** Read every line of your pull request before asking for review. If
+  you cannot explain what a change does and how it fits the rest of the system without asking an
+  AI, do not submit it yet.
+* **Disclose meaningful AI help.** Say which tool you used and roughly how much it wrote in the
+  pull request description (for example "drafted with Claude Code, reviewed and tested by me").
+  Autocomplete and spell-checking do not need a note.
+* **Write issues yourself.** An agent can help you research, but the report should be in your own
+  words, trimmed to what matters, with reproduction steps you ran. Long generated text that nobody
+  checked puts the burden on maintainers.
+* **Think before you generate.** Agents jump to code and make their own job easy: trivial tests,
+  wide or optional types, swallowed errors, redundant comments, copied local patterns that do not
+  fit. Push back on all of it. [RULES.md](RULES.md) lists the standards to hold the output to.
+* **Verify.** Run the checks in [CONTRIBUTING.md](CONTRIBUTING.md), use the app, and attach
+  screenshots for UI changes. "The agent said it works" is not a test result.
+* **Answer automated review.** If a bot reviews your pull request, fix its findings or reply with
+  a one-line reason a finding does not apply.
+* **No bulk or drive-by pull requests.** Many small generated changes across the tree, or changes
+  to something nobody asked for, will be closed. Open an issue first for anything beyond a small
+  fix.
+
+Pull requests that clearly skip these steps may be closed without a detailed review. Repeated
+low-effort submissions can lead to a block, under the [Code of Conduct](CODE_OF_CONDUCT.md).
+
+## For coding agents
+
+Read [AGENTS.md](AGENTS.md). It holds the commands, conventions and guardrails an agent working in
+this repository should follow.
+
+## Why
+
+Every issue and pull request is read by a person. Review time is the scarce resource, and a change
+nobody understood costs more than it saves. AI that is reviewed, tested and understood by the
+person submitting it is a good way to build PaperCraft; AI used to skip that work is not.

+# Code of Conduct
+
+PaperCraft is built by people with different backgrounds and experience. We want everyone to be
+able to contribute without harassment.
+
+## Our standard
+
+Be respectful and constructive. Assume good intent, give specific and kind feedback, and accept
+it the same way. Disagree about the work, not the person.
+
+Not acceptable:
+
+* harassment, insults, slurs, or personal or political attacks;
+* sexualised language or imagery, or unwelcome attention;
+* threats, doxxing, or publishing someone's private information;
+* sustained disruption of discussions, or pressure to merge or answer;
+* anything else a reasonable person would consider inappropriate in a professional setting.
+
+## Scope
+
+This applies in issues, pull requests, discussions, commit messages and any space where someone
+represents the project.
+
+## Enforcement
+
+Maintainers may edit or remove comments, close or lock threads, and block people who break these
+rules. To report a problem, use GitHub's "Report content" on the comment, or contact a maintainer
+through a private channel on their GitHub profile. Reports are handled privately and in good
+faith, and retaliation against a reporter is itself a violation.
+
+The spirit of this text follows the [Contributor Covenant](https://www.contributor-covenant.org).

+# Contributing to PaperCraft
+
+Thanks for wanting to help. PaperCraft is an alpha, so there is plenty to do and the bar for a
+first contribution is low: a typo fix, a clearer error message, a missing test or a one-line bug
+fix are all welcome.
+
+Please read [RULES.md](RULES.md) before writing code: it holds the standards a change is judged by.
+By taking part you agree to the [Code of Conduct](CODE_OF_CONDUCT.md). Using an AI tool is fine;
+the [AI usage policy](AI_POLICY.md) says what you stay responsible for, and coding agents should read
+[AGENTS.md](AGENTS.md).
+
+## Ways to help
+
+* **Report a bug** or **suggest a feature** with an [issue](https://github.com/nxtime/papercraft/issues/new/choose).
+  A screenshot or a short recording helps; so does the project folder (or a page of it) that
+  triggers the bug.
+* **Pick something from [ROADMAP.md](ROADMAP.md).** Rows marked `todo` or `partial` are open. Say
+  which one you are taking in an issue first, so two people do not build the same thing.
+* **Improve the docs, skills or screenshots.** [docs/](docs), [skills/](skills) and the README are
+  as important as code.
+* **Review a pull request.** A second pair of eyes is always useful.
+
+Security problems do not go in public issues: see [SECURITY.md](SECURITY.md).
+
+## Before you start
+
+For anything bigger than a small fix, open an issue (or comment on one) describing the problem and
+how you plan to solve it. Large features start as a short spec in [specs/](specs): a `spec.md`
+(why, what, what is out of scope) and a `plan.md`. [specs/component-props](specs/component-props)
+shows the shape. A spec agreed up front saves a rewrite later.
+
+## Set up
+
+You need Rust 1.95 or newer (`rust-version` in `Cargo.toml`) and the platform libraries listed in
+the README's [Build from source](README.md#build-from-source).
+
+```sh
+git clone https://github.com/nxtime/papercraft
+cd papercraft
+cargo build --release
+```
+
+Run a test copy next to your own PaperCraft so it cannot touch your real projects or collide with
+the running app's MCP port:
+
+```sh
+PAPERCRAFT_HOME=/tmp/pc PAPERCRAFT_MCP_PORT=29998 ./target/release/papercraft
+```
+
+`PAPERCRAFT_HOME` moves the project root and the config folder; `PAPERCRAFT_MCP_PORT` moves the
+MCP server. Always set both when developing.
+
+The code depends on [`craft-ui`](https://git.marcospaulo.dev.br/masi/craft-libs), which Cargo
+fetches from a public git repository at the revision pinned in `Cargo.toml`.
+
+## Make the change
+
+1. Fork the repository and branch from `main` (`fix/short-name`, `feat/short-name`).
+2. **Write the test first.** Fix a bug by adding a test that fails, then make it pass. See
+   [Tests](#tests).
+3. Keep the change focused. One concern per pull request; unrelated cleanups go in their own.
+4. Run the checks below and fix what they report.
+5. Update the docs the change touches: the README, `docs/`, the tool description for an MCP tool,
+   the skills if agents should now behave differently.
+6. Add a short entry to [PROGRESS.md](PROGRESS.md) for user-visible changes.
+
+### Checks
+
+```sh
+cargo fmt --all
+cargo clippy --all-targets
+cargo test --test <target>                            # the targets your change touches
+cargo check --lib --target wasm32-unknown-unknown     # the web build
+```
+
+Each file in `tests/` is its own binary linking the whole app, so the full suite is slow and heavy
+on a desktop. It runs on GitHub instead: before every release (`.github/workflows/test.yml`), or
+on demand with `gh workflow run test.yml -f ref=<branch>`.
+
+Keep the tree free of the third-party branding patterns listed in `.debrand`.
+
+### Tests
+
+* Unit tests sit next to the code in `#[cfg(test)]` modules.
+* Scenario tests live in [tests/](tests). They drive the editor with synthetic pointer and
+  keyboard events; `tests/mcp.rs` covers every MCP tool on a headless session.
+* Aim for **80% coverage** on code you add or change, including the error paths.
+* GPU-dependent tests skip when no adapter exists. Set `PAPERCRAFT_REQUIRE_GPU=1` to make them
+  fail instead.
+* `tests/update.rs` cannot run on Windows (it needs elevation); that failure is known and not
+  yours.
+* For UI work, run the app, look at it, and attach a screenshot. Headless rendering needs no
+  display: `papercraft --screenshot ui.png --demo --size 1440x900 --scale 2`.
+
+## Commits
+
+[Conventional commits](https://www.conventionalcommits.org): `type(scope): summary`, with the
+types `feat`, `fix`, `refactor`, `docs`, `test`, `chore`, `perf` and `ci`.
+
+```
+fix(ui): keep the review row's revert button off the hover edge
+feat(mcp): add set_screens
+docs(readme): add the demo video

+## Pull requests
+
+* Fill in the template: what changed, why, how you tested it, screenshots for UI changes.
+* Keep it reviewable. If it grows past a few hundred lines of non-generated code, split it.
+* The branch must be up to date with `main`; rebase rather than merge.
+* Expect review comments; they are about the code, not you. Push fixes as new commits and we
+  squash on merge.
+* A maintainer merges once a review is approved.

 * **Not carried over**: comments, design tokens, AI image generation, video export, teams;
   moving layers between pages; remote image URLs (see README Known gaps).
 
+### 2026-10-28: overflow lint rule and `get_bounds`
+
+* `lint_design` has an `overflow` rule (`src/mcp/lint_overflow.rs`): layers past their artboard or clipping parent, and text taller than its box. Scrolling frames and what is pinned in them are exempt; it is never auto-fixed. It is a pure function over a node set, so a scope filter can pass any subset.
+* New tool `get_bounds {nodeIds?, pageId?, depth?}` (`src/mcp/bounds.rs`): every layer's rect in one read (about 2000 rows per call, then `continueWith`). Tool count is now 87 (one more than before; if another branch also adds a tool, recount). Tests: `tests/mcp_bounds.rs`.
+
+### 2026-10-28: agent reads no longer look like edits
+
+* Read-only tool calls (`get_node_info`, `get_children`, ...) have honest verbs ("Looking at the design") and light the "Working" pill for 1.5 s instead of 6 s, so it goes out right after a sweep ends.
+* A sweep of reads draws at most one layer outline (a read outlines only when no other read ran in the last 2 s) and no longer pans the follow-agent camera; edits behave as before. "Is this a read" comes from `mcp::tools::edits_doc`.
+
+### 2026-10-28: 0.9.0 (presentations, critique, several agents, lighter chats)
+
+* Export the screens as a presentation PDF: cover, contents and a slide per screen (File menu, palette, `--format presentation`, `export_presentation`).
+* `critique_design` reviews finished work through personas (vision, UX, flow, QA, visual, accessibility, copy, end-user); `design_lessons` keeps the findings the person approved for every later design.
+* Several agents on one project: named CLI agents (`--as`), conflict reports and `ifRev` on writes, `claim_nodes` / `release_claims` / `list_claims`, scoped delegate builds and per-agent undo. 94 tools.
+* Screens keep their device height and scroll what does not fit; sections group screens on the canvas; pages can carry icons.
+* UI kits for shadcn, MUI, Mantine, Bootstrap and Chakra; `write_html` follows the browser more closely.
+* Memory: chat screenshots move to files (kept 14 days), thumbnails stay small, canvas images decode only for the GPU. A long chat dropped from about 1 GB to about 400 MB.
+* Fix: long answer options in a question card wrap instead of widening the whole chat.
+
+### 2026-10-28: 0.8.4 (demo video, fresh screenshots)
+
+* README opens with a time-lapse of designing a habit-tracker app (`docs/demo.gif`, full video `docs/demo.mp4`), and every screenshot is retaken from that design.
+* Fix: the Performance overlay reads its settings from the project config folder, so `PAPERCRAFT_HOME` isolates it too.
+
+### 2026-10-28: 0.8.3 (menus, panel grips, narrow windows)
+
+* Menus open 6 px below their button, are at least 180 px wide and show an icon beside each item. Below 1100 px the hamburger opens every menu in one popup.
+* Side panels: a slim rounded grip in the gap resizes them (double click resets) and `/` hides or shows both. Panels size to their content and step aside when the window is too narrow for the canvas.
+* Sharper window buttons (pixel-snapped glyphs); the hamburger morphs into a back arrow while the File / Edit strip slides open and shut.
+* Fixes: lint Fix buttons no longer cover the issue text; review rows keep their badge and revert button off the hover edge; the Export button stays on one line.
+
+### 2026-10-28: 0.8.2 (refresh-rate cap, accurate RAM/CPU, toolbar)
+
+* Settings > Performance > Refresh rate is now a real frame cap applied live (30 to 360 Hz, 60 by default); **Auto** draws as fast as the display allows and is the default on macOS.
+* Performance Monitor: RAM is the private working set and CPU is divided by logical cores on Windows, so both match Task Manager.
+* Windows and Linux toolbar: a hamburger button shows or hides the File / Edit strip (remembered); the close button uses the theme's danger colour on the acrylic surface, with hover animation and a pointing-hand cursor.
+
+### 2026-10-28: 0.8.1 (Performance Monitor on Windows, Design tab speed)
+
+* Performance Monitor: RAM (working set) and CPU now show on Windows; before they were `n/a` there. The overlay and slow-frame badge judge frames against a refresh rate you pick in Settings > Performance: 30 to 360 Hz (144, 165 and 240 included), 60 by default.
+* Design tab: the lint and the open-feedback scan are kept until the document changes instead of walking every node each frame; a 12.6k-node page no longer drops to a few FPS while the tab is open.
+* Windows and Linux: window buttons in the toolbar; controls and acrylic come from craft-ui.
+
+### 2026-10-27: 0.8.0 (screens, packed pages, canvas performance)
+
+* Screens (`specs/screens`): a frame can be declared a screen or an overlay (drawer, modal, sheet) with `set_screens`, inspector toggles, or Declare N screens on the page. Agent edits to layers hidden behind an overlay or opaque layer in their screen are refused unless `allowHidden`; partly covered ones are reported with their visible share. `get_basic_info` lists screens, `get_node_info` tells a layer's visibility, `lint_design` skips hidden layers, On click lists screens, nested screens get canvas labels.
+* Pages and saved versions are stored as zstd-compressed compact JSON (`.json.zst`, project format 3): the 68 MB Interview project is 1.3 MB on disk and loads faster. A legacy `.json` still reads and is replaced on the next save; older builds refuse format 3.
+* Canvas performance: the editor logs which layers each change touched, so the scene cache re-tessellates only those and keeps no copy of the document (443 → 346 MB on Interview). Zoom holds its geometry until it settles, tiny layers are skipped, vertices are 24 bytes, redraws follow vsync, the idle pointer no longer redraws, freed memory goes back to the system when idle, off-screen frame labels are skipped, and the layers panel keeps its row heights between frames (panning a large page: ~9 → ~0.7 ms a frame).
+* Frame labels: none on frames too narrow on screen, overlapping labels are dropped (selected and larger frames first), long names end in an ellipsis.
+* Dropdowns size to their longest option (capped), keep the name of `A / B / Name` options, scroll when long and show the full name on hover.
+* Settings: a Performance page (FPS, frame time, RAM, CPU, GPU, optional overlay and slow-frame badge), agent logos in the agent rows; the Chat page no longer collapses.
+
+### 2026-10-25: 0.8.0 (properties modal, row merges)
+
+* Properties modal (inspector, on a main: Edit properties…): a tab per property (name, kind, layer, default, delete); an options property as a Table (a row per option, a column per layer · style; colours picked from the project's variables with a swatch, visibility as a toggle, icon, image and text fields; add or remove options and columns) or as Source (each option's changes as JSON with syntax highlighting); templates from the + Property menu; Save replaces them all. The inline list is name, kind and a remove button. The `status` template writes colours the project has as variables as those variables.
+* Canvas overlays (agent glow, agent outlines, review outlines, the agent-elsewhere chip) sit below modals instead of showing through them. Two segmented controls in one row no longer share widget ids (the second did not respond).
+* `merge_variants` keeps what each moved instance shows (texts that came from its old variant), carries nested instances' property values (a badge's Tone) in the options, and takes `textLayers` for state texts only.
+
+### 2026-10-25: 0.8.0 (prototype links tool, merge icon colours)
+
+* `set_prototype_links`: agents can link a layer to a screen for Present mode (back arrows, rows, tabs); before, only the inspector could.
+* `merge_variants` compares an icon's colour (keeping its variable), now that icons are compared as one unit.
+
+### 2026-10-25: 0.8.0 (data safety fixes)
+
+* Sync no longer throws away an instance written over a nested one the way older versions stored it (its own root, no swap): it becomes a swap of the main's child at that place. Projects built before #11 lost such layers (a checked checkbox, a status badge) on the next edit of the outer main.
+* Icons: the HTML parser keeps attribute names in lowercase, so the icon and plugin code never removed the SVG's original `viewBox`; since #14 that made `<x-paper-icon>` (and icon swaps) scale twice and come out tiny. Unreleased builds only; 0.7.3 is not affected.
+* `merge_variants` refuses merges that would leave one option and changes nothing then.
+
+### 2026-10-25: 0.8.0 (merge variants, pinned bars)
+
+* `merge_variants`: per-state components (`Tab bar / Hoje`, `Status / Sucesso`...) become one component with an enum property. Each variant's differences from the base, matched by layer path (fills, colours, borders, weight, radius, visibility, icons; texts on request), become its option; every instance on every page moves to the base with its value; the base takes the family name; the emptied variants are deleted. A variant with layers the base lacks is left out and reported.
+* Absolute children of a scrolling screen stay pinned while its content scrolls (a tab bar, a floating button), and do not add to the scroll range.
+
+### 2026-10-25: 0.8.0 (fix #22)
+
+* #22: a hug column whose width comes from its parent (stretched or filled) re-measures its height once its text wraps at that width, and the parent measures again, instead of keeping a height measured while the text was narrow.
+
+### 2026-10-25: 0.8.0 (component properties)
+
+* Main components carry properties (`Node.props`): `text`, `bool`, `icon` and `enum`, whose options are changes in the overrides format (a layer name, `$root` or a path `Item > Label`, to a text or styles that may hold `text`, `icon` and `visibility`), so they restyle, retext, show, hide or re-icon any layer. Instances keep their values (`prop_values`) as overrides, so main edits keep them; changing the definitions re-applies every instance on every page.
+* Templates: `text` (a property per text layer), `active` (which item of a tab bar, nav or segmented row is active) and `status` (options with a colour tint the root and colour the label and icon).
+* `set_component_props`, `set_instance_props`, `props='{...}'` on `<x-paper-instance>`, properties in `get_components`, `{Prop}` in code link templates, and an inspector section (a control per property on an instance; Texts and Active item templates on a main). Icon swaps keep the layer's name and link (a `children` override); recoloured icon shapes inside instances now keep their colour after a sync.
+* Spec: `specs/component-props/spec.md`.
+
+### 2026-10-25: 0.8.0 (scrolling screens)
+
+* Screens keep their size and scroll what overflows: a frame's `scroll` flag (CSS `overflow: auto|scroll`, `overflow-y-auto` in the Tailwind export) makes it fixed height and clipped, and the wheel over it scrolls its content on the canvas and in Present, then pans once the content ends. The offset is view state, not saved; hit-testing and overlays follow it.
+* Toggles: a scroll button beside each screen's name (shown when it scrolls, overflows, or is hovered), Scroll overflow on a selected frame, and Screens scroll on the page for every screen at once. A fit-content screen that grew goes back to its min height.
+* Agents are told to keep screens at their size and use overflow:auto for long content.
+
+### 2026-10-25: 0.8.0 (fixes #19, #20, #21)
+
+* #19: a clipping frame draws its border after its children, so filled rows no longer hide it. Clipping stays rectangular: children's square corners still show past a rounded border.
+* #20: a border written with a colour variable (`1px solid var(--border)`) binds the stroke, a literal one unbinds it, and reads show `var(--name)` for bound strokes. `find_nodes` says when it stopped at 500 matches.
+* #21: hug (fit-content) frames grow around growing children (CSS flex-basis auto) instead of staying at their min height; with short content the min height stays and the growing child fills it, so a pinned footer works.
+
+### 2026-10-25: 0.8.0 (follow agents, skeletons)
+
+* Follow agents (Settings, Chat; on by default): in Design and Chat mode alike, the canvas pans, and switches page, to the layer any agent changes (the chat, Claude Code over MCP, a helper). Moving the canvas yourself pauses it for a moment; off, a chip offers the agent's page.
+* Skeletons: the moment the model starts writing a tool call (`ToolDraft` and `ToolInput` events from Claude Code's stream and the API), the canvas shows a shimmering skeleton over its target, or where a new artboard goes, labelled with what it is doing, until the call has run. Fresh agent content comes in through a skeleton that fades, so an outline never frames empty space.
+* Top bar: the title and the agent pill leave room measured from the buttons on the right, so nothing overlaps at narrow widths.
+
+### 2026-10-25: 0.8.0 (fixes #14 to #18)
+
+* #14: `write_html` fits an `<svg>` viewBox into its width and height like a browser (centred, aspect kept).
+* #15: a note on something placed straight in its artboard treats the artboard as the screen: tidy keeps cards off it instead of in its free space.
+* #16: `not-an-instance` no longer matches look-alikes with a different icon; its fix names the `<x-paper-instance>` to write (swap_instance refuses plain frames).
+* #17: instances with their own text re-measure it when the main's text style changes, so hug buttons keep fitting their labels (also covers the size reset after a swap).
+* #18: `lint_design` reports borders whose hex equals a color variable, and `fix` binds them (`stroke`), so a mode switch reaches them.
+
+### 2026-10-25: 0.7.3 (QA sub-agent, helper agents, auto mode, mid-turn messages, isolated dev settings)
+
+* QA sub-agent: Claude Code chats always get a Sonnet `qa` agent that lints and screenshots built frames and returns only findings, so screenshots stay out of the main context.
+* Helper agents (`src/mcp/delegate.rs`, Settings, Chat, Helper): `delegate` hands `qa`, `read` or `build` tasks to a cheaper agent CLI (pi with MiniMax M3.1 Flash, opencode, an Ollama-backed agent, any command taking `{prompt}`). It drives PaperCraft through `papercraft-cli`, runs off the UI thread, and only its last 6,000 characters come back. With a helper set, the chat agent orchestrates: keeps the brief and taste, delegates review, bulk reading and fully specified edits.
+* Dev config isolation: `PAPERCRAFT_HOME` also isolates the chat settings (`$PAPERCRAFT_HOME/.config`), so a second copy for testing never touches the installed app's settings.
+* Live check in an isolated copy: `delegate` ran the pi helper (MiniMax M3.1 Flash) as QA, a message added mid-turn went Waiting then Seen, and the agent drafted #13.
+* Fixes #10, #11, #12, #13:
+  * #10: `move_nodes` to another page keeps mains' component keys and relinks every instance to moved nodes; new `rename_file` renames a project.
+  * #11: swapped nested instances persist as swap overrides (`InstanceLink.swap`), preserving component identity across outer component updates and copies.
+  * #12: `move_nodes` to another page takes the moved nodes' annotations along; detached notes resolve as `Detached #n`.
+  * #13: `get_computed_styles` reports a text colour bound to a variable as `var(--name)`.
+* Auto mode (the composer's Auto chip): when a turn ends on `ask_user` questions, the first (recommended) option of each is sent and the chat goes on, until Stop or a turn hits its budget. The agent is told to put its recommendation first, default what only the user can know, and end each turn with next steps.
+* The Present button uses a play icon drawn like the icons beside it. Composer chips wrap instead of running under Stop and Add. Top bar: the agent pill drops its text when it would run under the buttons on the right.
+* While a chat turn works, the composer's Add (or Enter) queues a message (`src/mcp/steer.rs`). It rides on the agent's next PaperCraft tool result for that chat, so every backend reads it mid-turn; the composer shows each as Waiting or Seen. What no tool call picked up is sent as the next message when the turn ends, or goes back into the box after Stop.
+
+### 2026-10-24: 0.7.2 (UI kits, code links, issues from the app, design playbook)
+
+* Code links (Figma Code Connect style): a main component carries its library import and a React and an egui template (`set_code_link`). The React, Tailwind, inline JSX and egui exports write linked instances as that code, with overrides filled in and imports gathered once; the AI spec lists them as Library Components with a "use it, do not rebuild it" rule and stops describing their inner layers.
+* UI kits (`src/ui_kits.rs`, `apply_ui_kit`): shadcn/ui, Ant Design, React Bits and egui, each with Light and Dark variables, tokens and components in its look and density, all linked. The chat brief asks for the code library and starts from its kit.
+* Issues from the app (`src/issues.rs`): the agent's `report_issue` draft card (Send or Discard) and a Report a PaperCraft issue form, filed on the repository in Settings (token in the keychain, else the `tea` login), de-duplicated by title against open and closed issues.
+* design-playbook in the chat: with the `playbook` CLI installed, the brief asks whether to follow the playbook and the agent looks rules up with `design_rules`, citing ids in its report.
+* Top bar: project name and page picker on one centred row; the two-row title had outgrown the bar and covered the canvas.
+* Evidence: `src/ui_kits.rs`, `src/issues.rs`, `src/mcp/codegen.rs` (`linked_components_export_as_library_code`), `specs/ui-kits/spec.md`.

+last 10000 layer changes, each with the client that made it) now records which layers every
+commit, undo and redo touched; variable edits count as touching the layers bound to them. Write
+tools return `rev`, `get_basic_info` reports it, `get_changes {since, page?, exclude?, by?}` lists
+the changes, and `lint_design {since | changedOnly}` checks only those layers plus their
+ancestors, descendants and siblings (`src/mcp/incremental.rs`), with `covered` saying what ran.
+Tests: `tests/incremental.rs`, unit tests next to the code, the attribution check in
+`tests/mcp.rs::parallel_sessions_get_their_own_runs`.

 ### 2026-10-21: Design libraries and offline CLI
 
 * Variables are now collections with modes, slash groups, four types and aliases, stored in `design.json` (project version 2; 0.4.0 refuses migrated projects). Each page keeps a derived cache; every edit is one undo step per page, and the page-only removals are gone. Per-page active mode per collection.

 ## Status and known limits
 
 > [!IMPORTANT]
-> PaperCraft is an alpha. [ROADMAP.md](ROADMAP.md) lists what is missing, in priority order; [PROGRESS.md](PROGRESS.md) is the milestone history.
+> PaperCraft is an alpha (0.8.x). It is used daily on Windows, macOS and Linux, and its project format migrates forward, but expect rough edges. [ROADMAP.md](ROADMAP.md) lists what is missing, in priority order; [PROGRESS.md](PROGRESS.md) is the milestone history.
+
+**What works today:** local projects with pages and an infinite canvas; vector, text, auto layout, constraints, components with properties and variants, variables with modes, shared libraries and screens; annotations, lint and Present mode with prototype links; PNG, SVG and PDF export, Figma, Excalidraw and SVG import; the MCP server, CLI (online and offline) and in-app Chat mode; versions, agent runs with review and revert; optional relay sync.
+
+**Known limits:**
 
 * **No rotation.** Nodes are axis-aligned boxes; rotated imports are baked into paths.
 * **Text** is Inter only, with no shaping (no ligatures, complex scripts or RTL) and no font picker. IME preedit is not displayed.
 * **Rendering approximations.** Frame clipping is a rectangle, so rounded frames do not clip their corners. Overlay, dodge, burn, light, difference, exclusion and the HSL blend modes draw as Normal on the canvas (they are exact in SVG and PDF export). There is no layer or background blur yet.
-* **Variables:** gradients keep fixed colors; there are no text styles and no component variants or properties.
+* **Variables:** gradients keep fixed colors, and there are no text styles (named type styles that update every text layer).
+* **Components:** properties (text, bool, icon, enum) and `merge_variants` cover variants, but there are no variant sets with several axes, and no responsive per-breakpoint variants or breakpoint preview.
+* **Prototyping:** links and flows work in Present mode; smart transitions and hover states do not exist yet.
 * **Booleans are destructive:** the result is a new vector path with flattened curves.
 * **`write_html`** ignores margin, tables and transforms (it reports them as `ignoredStyles`) and does not fetch remote images; pass a local path or a `data:` URI.
 * **Agents:** one project is open at a time in the app, and `move_nodes` stays on one page. The in-app Chat mode runs Claude Code, Codex, ACP agents or your own Anthropic key. Agents that are not in Chat connect over MCP or the CLI.
 * **Sharing** has no live presence (cursors, selections) yet.
+* **Scale:** cached frames take about 3 ms at 10k visible nodes; it is not tuned for 100k.
 * **Pen pressure** is simulated from stroke velocity on macOS tablets, because winit 0.30 does not expose it for mouse-like pen events.
-* **Releases** cover macOS (Apple silicon) and Linux x86_64. Windows packaging scripts exist but are not part of releases.
+* **Releases:** the Gitea releases ship Windows x86_64. macOS (Apple silicon) and Linux x86_64 builds come from the packaging scripts or from source; the Linux build is not part of the current releases.

+# Project rules
+
+The standards a change to PaperCraft is reviewed against. [CONTRIBUTING.md](CONTRIBUTING.md) says
+*how* to contribute; this file says what "good" means once you do.
+
+## Code
+
+* **Immutability by default.** Return new values rather than mutating shared ones. The document
+  changes only through `Editor::edit` transactions, so every change is one undo step and is
+  logged for the renderer's cache.
+* **Small, cohesive files.** 200 to 400 lines is typical, 800 is the ceiling. Split a module
+  when it grows past that. Organise by feature, not by type.
+* **Small functions** (under about 50 lines) and **shallow nesting** (4 levels at most); prefer
+  early returns.
+* **Handle errors explicitly.** No `unwrap` or `expect` on user data, file contents or network
+  responses; return an error with context. User-facing messages are plain language. Never swallow
+  an error silently.
+* **Validate at the boundaries**: MCP and CLI arguments, imported files (Figma, Excalidraw, SVG),
+  project folders and anything from the relay. Treat all of it as untrusted.
+* **No magic numbers.** Name thresholds, sizes and delays as constants; UI measures come from
+  the theme, not literals.
+* **No dead code, debug prints or commented-out blocks.**
+* **Match the surrounding code**: naming, comment density and idiom. Comments say *why*, not
+  *what*.
+* **Cross-platform.** Code must build on Windows, macOS and Linux and for the web build. Gate
+  platform code with `cfg`, never assume a path separator, and keep
+  `cargo check --lib --target wasm32-unknown-unknown` passing.
+* **No new heavy dependencies** without discussion. Licenses must be compatible with
+  MIT OR Apache-2.0.
+
+## Data safety
+
+PaperCraft stores people's work. Treat that as the top priority.
+
+* Writes to projects are **atomic** (`src/io/atomic.rs`); never write a page in place.
+* A format change bumps the project format version and ships a **migration**. Older data must
+  keep loading; if a newer build writes something an older build cannot read, the older build
+  must refuse it rather than corrupt it.
+* Agent and sync paths must never silently drop a layer. If a merge cannot keep something, it
+  says so.
+* Destructive operations are undoable or confirmed.
+
+## The machine you build on
+
+A full build links dozens of test binaries and can take every core and most of the memory of a
+desktop. The person is still using that machine, often with PaperCraft open.
+
+* **Look before you start a heavy job.** Check free memory, CPU load and what is already running
+  (the person's app, another build, other agents) before a build, a test run or clippy. If memory
+  is short or another build is running, wait or ask.
+* **Leave room.** Cap Cargo at no more than half the logical cores (`-j 8` on a 16-core machine,
+  or `CARGO_BUILD_JOBS`) and the test harness too (`-- --test-threads=8`); go lower when memory is
+  tight, since linking is the peak. Run heavy jobs at low priority (`nice` on Unix, Below Normal
+  on Windows).
+* **One heavy job at a time.** Never run two builds side by side; each target folder is a full
+  build's worth of compiling and linking. Parallel agents share one build slot.
+* **Run only what your change touches**: `cargo check` before `cargo build`, and the test
+  targets that cover the change (`cargo test --test incremental`). The full suite runs on GitHub
+  before a release (`.github/workflows/test.yml`), not on a desktop.
+* **Stop at once when the person says the machine is slow**, then check that no compiler, linker
+  or test process of yours is left over.
+* **Clean up.** Delete scratch target folders and worktrees when the work is merged; they grow to
+  tens of gigabytes.
+
+## UI
+
+* **Use the shared kit.** Controls, spacing, radii and colours come from `craft-ui`,
+  `src/ui/kit.rs` and the theme, not one-off values.
+* **Themes are modes.** Never branch on a theme to pick a colour; read it from the palette.
+* **Nothing overflows.** Text truncates with an ellipsis, rows keep their controls inside, and
+  panels step aside when the window is narrow. Test a narrow window and a long name.
+* **Targets are at least 44 px** where a person taps or clicks something primary, and everything
+  stays reachable from the keyboard.
+* **Animation is quick**: eased and under about 200 ms.
+* **Look at it.** Run the app or take a headless screenshot at scale 2 in each theme before
+  asking for review.
+
+## MCP tools and the CLI
+
+* Every tool has a precise one-paragraph description, a JSON schema, and a test in
+  `tests/mcp.rs`. Descriptions are what agents read; write them for that reader.
+* One tool call is **one undo step**.
+* Names follow the existing style (`verb_noun`); reuse Paper-compatible names and argument shapes
+  where a tool has an equivalent.
+* Reads are cheap and bounded. Apply limits, say when you truncated, and never dump the whole
+  document by default.
+* The server listens on `127.0.0.1` only and rejects browser origins. Do not weaken that.
+* Update the tool count in the README and ROADMAP when you add or remove tools.
+
+## Designs made with PaperCraft
+
+These apply to example projects, templates, screenshots and skill content, and are what the
+skills teach agents.
+
+* **Themes are modes, never copies.** One artboard per screen. Give each variable a value per
+  mode and switch with `set_variable_mode`. Do not duplicate artboards as light and dark
+  versions, and do not rebuild a screen with other hex values.
+* **Every colour on a themed screen is a variable** (`var(--name)` on fills and text,
+  `bind_variable` for strokes, opacity and visibility).
+* **No overflow.** Nothing extends past its artboard or clipping parent. Scrolling content is
+  clipped inside its viewport and ends above floating bars with a fade and enough bottom padding.
+  Check each artboard programmatically *and* by screenshot in each mode.
+* Run `lint_design` and fix what it finds: contrast, the 4 px grid, type scale and 44 px targets.
+* Release design locks when you are done so the next person can inspect.
+
+## Skills and docs
+
+* Skills in [skills/](skills) are instructions for agents: keep them short, concrete and tested
+  against a real agent run.
+* Docs describe what exists. Do not document a feature that is not built; put plans in `specs/`
+  and `ROADMAP.md`.
+* Screenshots come from the real app, in a generic project (no personal data, local paths or
+  real names), at scale 2.
+
+## Branding
+
+The tree carries no third-party product branding; `.debrand` lists the forbidden patterns and
+the check runs in review. Describe PaperCraft on its own terms.

+## Review
+
+A pull request is approved when it has no unresolved **critical** (security, data loss) or
+**high** (bug, significant quality) issues. Medium and low comments are suggestions the author

+# Security policy
+
+## Supported versions
+
+PaperCraft is an alpha. Security fixes go into the latest release and `main`.
+
+## Reporting a vulnerability
+
+**Do not open a public issue.** Use GitHub's private reporting: the repository's **Security** tab,
+then **Report a vulnerability**. Include what you found, how to reproduce it, the version and
+platform, and the impact you see.
+
+A maintainer will acknowledge the report as soon as they can and keep you updated until it is
+fixed. Please give us reasonable time to ship a fix before you disclose it.
+
+## What counts
+
+Examples of in-scope problems:
+
+* the MCP server (`127.0.0.1:29980`) or the relay accepting requests it should reject (browser
+  origins, DNS rebinding, another user);
+* path traversal or code execution from a project folder, a design-system or library package, or
+  an imported Figma, Excalidraw or SVG file;
+* the updater or the agent integrations running something the person did not approve;
+* secrets (an Anthropic key, relay tokens) written to disk unprotected or sent anywhere
+  unexpected.
+
+PaperCraft is local-first: it opens no network port beyond the loopback MCP server unless you
+share a project through a relay you run.

+## Checking only what changed
+
+On a big page a full `lint_design` after every edit repeats the same output, and a `get_node_info` call per layer is slow (about 53 s for 397 layers). Check the change, then check everything once.
+
+* Every write tool result includes `rev`, the document revision after the call. `get_basic_info` reports the current `rev`. Reads never change it.
+* `get_changes {since, page?}` returns `{rev, since, truncated, changes: [{page, ids}]}`: what the edits since `since` touched. `truncated: true` means the log no longer reaches that far back, so do a full pass.
+* `lint_design {changedOnly: true}` lints since this client's last lint; `{since: rev}` lints since a revision you name. A scoped lint checks the touched layers plus their ancestors, descendants, siblings and every layer bound to a changed variable, and reports its coverage in `covered`, for example `{checked: 12, total: 397, since: 40, partial: true}`. Plain `lint_design` is a full pass (`partial: false`). The `overflow` rule flags a layer that extends past its parent or clipping artboard (scroll frames are excluded).
+* `get_bounds {nodeIds?, pageId?, depth?}` returns `columns` `[id, parent, x, y, w, h, absX, absY, clip]` and one row per layer for a subtree in one call (at most 2000 rows; then `truncated` and `continueWith`, the nodeIds for the next call). Use it instead of looping `get_node_info`.
+* Always finish with one full `lint_design` (no arguments) and a screenshot per artboard in each theme mode before reporting. A partial lint speeds up the loop; it does not replace that pass.
+
+In the app, read-only calls no longer draw per-layer outlines or keep the "Working" pill lit for long. The agent workflow, with an example, is in [incremental-checks.md](../skills/papercraft/references/incremental-checks.md).
+
 ## Design-system tools
 
 * Variables: `get_variables` and `set_variables` take collections, groups (`color/brand/primary`), types (`color`, `number`, `string`, `boolean`), `mode`, `alias`, `description` and `hidden`; the old `{"name":"#hex"}` call still works and lands in the first collection. `create_collection` makes a collection with modes, `delete_variables` removes by name (refuses aliased ones unless `force`), `bind_variable` binds or detaches a field of layers (`stroke`, `text-color`, `width`, `height`, `gap`, `padding`, `radius`, `font-size`, `line-height`, `opacity`, `visible`).

 The ACP agents PaperCraft knows about, and what was checked on the development Mac:
 
-* **OpenCode** (`opencode acp`): works.
-* **Gemini CLI** (`gemini --acp`): found and started, but its server currently refuses ACP clients, so turns fail with the agent's error until Google changes that.
+* **OpenCode** (`opencode acp`): works. Its free models (`opencode/*-free`, Big Pickle) need no key.
 * **Cursor** (`cursor-agent acp`): sign in first with `cursor-agent login`.
-* **Pi** (`pi-acp`, an adapter run through `npx`): enable it once in the agent panel or Settings, then it works like the others.
+* **Pi** (`pi-acp`, an adapter run through `npx`): enable it once in the agent panel or Settings. `pi-acp` does not pass MCP servers on to Pi, so a lean Pi gets its own folder (`PI_CODING_AGENT_DIR`) whose only package is `pi-mcp-adapter`, connected to PaperCraft. Pi runs on the providers you add a key for in Settings → Chat → Pi: OpenRouter (`:free` models, 50 requests a day without credits), Groq, Gemini, NVIDIA NIM and Cerebras. Keys live in the OS secret store and reach Pi only as environment variables.
 * **Goose, Kimi, Devin, Junie, Mistral Vibe, Hermes, OpenHands, Stakpak, VT Code, Poolside, Droid**: started with the command their own docs give. They are not all verified here.
 * **Claude Code and Codex ACP adapters** (`npx`): listed under Enable via npx. Claude Code and Codex themselves use the direct backends above.
 
 Agents that run through `npx` are off until you enable them, because enabling runs code that npx fetches from npm.
 
+**Free models.** For OpenCode and Pi the model list starts on free models (`Free only`) and offers `Free (auto)`, the default for new chats on them. It starts on the free model with the largest context. When a model fails with a rate limit, quota, overload or "gone" error before any tool ran, the turn moves to the next free one (at most two more) and the thread says so. A model that failed is skipped for 15 minutes. A failure after a tool ran is not retried, because the design may already have changed.
+
 ACP permissions: PaperCraft's own tools run without asking, except the destructive ones listed under Approval below. Any other tool the agent asks to run (its own shell or file tools, for example) shows an approval card with Approve or Deny in the thread, and Deny is sent back to the agent.
 
 **Custom agents** are your own ACP agents: a name, a command (a program name on the resolved `PATH`, or a full path) and arguments. The arguments are split on spaces, with no quoting. Custom agents appear under Custom in the agent panel and in Settings → Chat.

Below them are `Add an API endpoint` and `Add custom agent`. When OpenCode or Pi is not found, its row has `Install…`. The dialog offers the install methods that work on this OS (Homebrew, Scoop, npm, Nix or the agent's install script; on Linux also the distribution's own). It shows the exact command and runs it only after you click Install, streaming the output. Methods that need `sudo` or an admin shell, and npm when Node is missing or too old, are shown with the reason and a command to copy instead.

-description: Pre-emit critique gate for work built in PaperCraft. Five panels (designer, critic, brand, accessibility, copy) score a screen 0-10 against PaperCraft's own objective evidence (lint_design, verify_code, get_screenshot, get_design_spec, get_variables), the weighted composite must reach 8.0, and a failed gate ships the best round instead of the last one. Use when an agent is about to hand over a PaperCraft screen and wants a tool-backed review instead of a self-praise.
+description: Critique finished PaperCraft work the way a design team does - against the person's objective, through independent reviewers (the person's vision, UX heuristics, flow across screens, QA states, visual, accessibility, copy, an end user from the audience), each finding rated 0-4 and backed by tool evidence, then fixed, reported and, when the person approves, kept as a lesson. Use when finish_working_on_nodes offers a critique, when asked to review or critique a design, or before handing over a screen or flow.

 # papercraft-critique
 
-A gate, not a compliment. Before a screen leaves the app it goes through five panels. Each panel is a rubric pass over the same artifact, and each panel may only cite what a PaperCraft tool actually returned. The panels produce five scores, the scores produce one composite, and the composite decides whether the work ships. Mechanics live in the `papercraft` skill, taste in `papercraft-design`; this skill is the gate.
+A critique judges a design against what it is for, not against taste. The tool `critique_design`
+hands you the evidence and the reviewers; this skill is how to run them. Mechanics live in the
+`papercraft` skill, taste in `papercraft-design`. Per-reviewer checklists:
+[personas.md](references/personas.md).
 
-Reference: [panels.md](references/panels.md) (what each panel inspects, which tool backs it, its 0–10 bands).
+## 1. When
 
-## 1. When the gate runs
+* `finish_working_on_nodes` returns `next`: ask the person (`ask_user`) whether to critique now.
+* The person asks "review this", "is it ready?", "critique it".
+* Before handing over a whole screen or flow. Not for one component, an early draft or a copy tweak.
 
-Run it when the resolver (section 2) says on, or when the request is a review of finished work:
+## 2. Objective first
 
-* a whole screen is about to be handed over: landing page, dashboard, sign-in, settings, an onboarding flow, a whiteboard plan;
-* a redesign of an existing screen, after the edits and a clean `lint_design`;
-* the user asked "does this look right?", "review this", "critique it", "is it ready to ship?".
+Critique without an objective is opinion. Before judging, have:
 
-Do not run it for: a single component or icon, an exploratory draft before a direction is chosen (the `papercraft-design` section 0 step), or a one-line copy tweak. The gate costs a lint and a screenshot per round; spend it on work that is finished.
+* **Objective**: what the work must achieve ("a returning customer reorders in two taps").
+* **Audience**: who uses it, in what context (phone, in a hurry, first visit, low vision).
+* **Top tasks**: the two to five things people come to do.
 
-If the gate is on for a run, it must produce a status. Never skip it silently: report `Degraded` with the reason.
+Take them from the brief, the spec, the person's notes (`get_feedback`) and references. Missing?
+Ask with `ask_user` and pass them to `critique_design {objective, audience}`.
 
-## 2. Enable resolver
+## 3. The reviewers
 
-Four levels, highest priority first. Take the first level that gives an explicit answer; "unset" falls through to the next one. A higher level saying *off* is final — a lower level cannot turn the gate back on.
-
-| Order | Level | PaperCraft equivalent | How to read it |
-|---|---|---|---|
-| 1 | Per-task policy | the instruction the agent was given for this run | "run the critique gate before you finish", "review this screen" |
-| 2 | Per-project setting | a toggle stored in the project's own metadata | **not implemented today** — PaperCraft has no project-level flag. Treat this level as unset and fall through to the environment flag or the per-task instruction |
-| 3 | Environment flag | `PAPERCRAFT_CRITIQUE_ENABLED` | `1` / `true` / `always` = on, `0` / `false` / `never` = off, unset = fall through |
-| 4 | Rollout phase | the release phase of the skill itself | off by default: the gate ships disabled until a run or a project turns it on |
-
-So today the gate turns on in one of two ways: the user asks for it in the run's instructions, or `PAPERCRAFT_CRITIQUE_ENABLED=1` is in the environment. A future project setting — stored with the project, not with the user — would sit between those two and win over the environment, so a project could opt in permanently without an env var.
-
-## 3. Order of operations
-
-Objective checks first, subjective panels second. A panel never scores above evidence that contradicts it.
-
-One round is: **evidence → repair → judge → score**.
-
-1. **Snapshot.** Note the `pageId` and the artboard `nodeId` under review and keep them for the whole gate. A page switch between rounds invalidates the evidence.
-2. **Evidence.** `lint_design` (`nodeId`, `pageId`, no `fix` yet) for the raw findings — the payload counts `errors`, `warnings` and `info`, groups them in `byRule`, and lists each issue with its `rule`, `severity`, `node`, `message` and `fix`; `get_screenshot` of the same node (`scale: 2` to read small text); `get_variables` for the token set and the active mode; `get_design_spec` (`nodeId`, `target`) when the design is headed for code. If there is code to check, `verify_code` (`nodeId`, `target`, `code`).
-3. **Repair the hard evidence.** Fix every `lint_design` error and warning and re-run the lint until it is clean; fix every `verify_code` violation until `passed` is true. A panel cannot be scored on a design that still carries a lint error.
-4. **Judge the five panels** on the evidence from steps 2–3 plus the screenshot. Every finding cites the tool result or the screenshot region behind it.
-5. **Score.** Five scores 0–10, then the composite (section 5). Composite ≥ 8.0 → status `Shipped`, stop, `finish_working_on_nodes`.
-6. **Otherwise fix and go again.** Take the findings in composite-impact order, fix them, run round N+1. Maximum 3 rounds.
-7. **Ship the best round** if round 3 is still below the threshold (section 6).
-
-The panels are rubric passes by the agent that holds the tools: one agent, five passes, five different rubrics. A runtime that can spawn subagents may run the panels in parallel, but the evidence vetoes, the composite and the round counter belong to the coordinator.
-
-## 4. Hard evidence vetoes a panel
-
-`lint_design` and `verify_code` are not suggestions. Each finding belongs to one panel, and that panel cannot score above the band its evidence forces.
-
-| Evidence | Rule | Owner panel | Cap |
-|---|---|---|---|
-| `lint_design` error | `contrast` | Accessibility (the Critic reads it too) | 3.9 |
-| `lint_design` warning | `text-size` (under 12px) | Accessibility | 6.9 |
-| `lint_design` warning | `spacing-grid` (off the 4px grid) | Designer | 6.9 |
-| `lint_design` warning | `touch-target` (under 44px) | Accessibility | 6.9 |
-| `lint_design` warning | `layer-name` (default names) | Designer | 6.9 |
-| `lint_design` warning | `hard-coded-color` | Brand | 6.9 |
-| `lint_design` info | `type-scale` | Designer | none — must be listed |
-| `verify_code` error | `missing-text` | Copy | 3.9 |
-| `verify_code` error | `hardcoded-color` | Brand | 3.9 |
-| `verify_code` error | `forbidden-absolute` | Designer | 3.9 |
-| `verify_code` error | `missing-layout` | Designer | 3.9 |
-| `verify_code` warning | `missing-component` | Brand | 6.9 |
-| `verify_code` warning | `spacing-drift` | Designer | 6.9 |
-
-An error caps the owning panel at 3.9 (Blocker band), a warning at 6.9 (Weak band), an `info` item caps nothing but must appear in the panel's notes. `hard-coded-color` arrives in both flavours: a warning when the color equals a variable that exists, an info when it is a literal used several times — the warning caps Brand, the info does not. The cap lifts as soon as the finding is gone; the next round re-scores the panel freely.
-
-A finding is evidence for its owner and a hint for the others: `contrast` also informs the Critic, `spacing-grid` also informs the Brand (was it the token or the layout?), but only the owner is capped.
-
-## 5. The panels and the composite
-
-| Panel | Judges | Weight |
+| Persona | Asks | Method |
 |---|---|---|
-| Designer | layout, composition, hierarchy, spacing rhythm, type scale in use | **0 in v1** — it still scores and its findings still drive the next round |
-| Critic | does it meet the brief; contrast, weight, readability | 0.4 |
-| Brand | token compliance, on-brand color, voice | 0.2 |
-| Accessibility | WCAG, focus rings, semantic structure, alt text | 0.2 |
-| Copy | voice, tone, terseness, error-message quality | 0.2 |
+| `vision` | Does it achieve the objective, as the person imagined it? | Objective, element, effect, why (Connor and Irizarry) |
+| `ux` | Can people use it without help? | Nielsen's 10 heuristics |
+| `flow` | Do the screens make one coherent journey per task? | Task walkthrough across screens, 4 questions per step |
+| `qa` | What breaks with real data and states? | State and edge-case matrix, pass/fail/n.a. |
+| `visual` | Does the eye land right, does it hold together? | Hierarchy, balance, contrast, gestalt, rhythm, tokens |
+| `accessibility` | Can everyone use it? | W3C POUR applied to a design |
+| `copy` | Is every word clear and specific? | Plain language, labels, errors, empty states |
+| `end-user` | Where would this user get stuck or give up? | Persona walkthrough of the top task |
 
-```
-composite = critic x 0.4 + brand x 0.2 + accessibility x 0.2 + copy x 0.2
-```
+`vision` always runs: the person's intent is the yardstick for the others. Pick the rest with
+`personas` (default: all). The person's own words outrank any reviewer.
 
-The weights sum to 1.0, so the composite is also 0–10. The Designer carries weight 0 in v1 on purpose: it is the panel most likely to argue with itself, so its score is reported and its findings are acted on, but it does not move the composite.
+## 4. Independence
 
-Each panel scores 0–10 in half-point steps. The composite is the weighted sum, rounded to two decimals.
+Several reviewers find far more than one, but only when they work apart (Nielsen: one
+evaluator finds about a third of the problems, three to five most of them). Reviewers who
+discuss or debate converge and amplify each other's bias.
 
-| Composite | Verdict |
+* **With subagents**: one subagent per persona, given only its persona brief, the objective and
+  the evidence. No reviewer sees another's findings before rating.
+* **Alone**: one pass per persona, in order, writing that persona's findings before reading the
+  next brief. Do not revise earlier personas' findings during later passes.
+* **You coordinate**: you merge and judge; you never let reviewers argue a finding out.
+
+## 5. Evidence
+
+From `critique_design`: lint (fix every error and warning first), the `flow` graph (arrows between
+screens, `deadEnds`, `unreached`), the lessons. Then `get_screenshot` each artboard at scale 1
+(2 for small text) in every variable mode, `get_bounds` for overflow, `get_feedback` for the
+person's notes. Every finding cites one of these: a tool result or a screenshot region. No
+evidence, no finding.
+
+## 6. A finding
+
+`persona`, `heuristic or check`, `element` (layer name), `seen` (the observation), `effect` (on
+the objective), `evidence`, `severity`, `suggestion`. Keep the observation and the suggestion
+apart: critique is analysis, not brainstorming. Each persona also names at least one thing that
+works and should stay.
+
+Severity (Nielsen), from frequency, impact and persistence:
+
+| | |
 |---|---|
-| ≥ 8.0 | Ship |
-| < 8.0 | Not shippable as is: fix and re-run, or ship the best round after round 3 |
+| 0 | not a problem |
+| 1 | cosmetic: fix if time allows |
+| 2 | minor: low priority |
+| 3 | major: fix before handing over |
+| 4 | catastrophe: blocks the task, fix now |
 
-The band legend is the same for every panel:
+Every broken lesson (`lessons`) is a finding of at least 3.
 
-| Band | Range | Means |
-|---|---|---|
-| Blocker | 0.0–2.9 | Broken: the panel's own evidence is violated. Cannot ship |
-| Poor | 3.0–4.9 | Works against the brief or the brand; ships visible damage |
-| Weak | 5.0–6.9 | Passable but noticeably off; expect a second round |
-| Acceptable | 7.0–7.9 | No blocker, but a reviewer would ask for one change |
-| Good | 8.0–9.4 | Ships as is |
-| Excellent | 9.5–10.0 | Reference quality for this project |
+## 7. Merge, fix, report
 
-What each panel inspects, which tool backs it and where its scores land: [panels.md](references/panels.md).
+1. **Merge** into one list: join duplicates, count the personas that found each (two or more is
+   confirmed), severity is the mean of their independent ratings.
+2. **Fix** every 3 and 4 with the smallest edit (`update_styles`, `set_text_content`), then check
+   that finding again with the same evidence. The work is ready when no 3 or 4 is open and lint is
+   clean. Three fix rounds at most; then hand over with the open findings stated.
+3. **Report** to the person: what works, then findings by severity, each with what was seen, the
+   evidence, the suggestion and whether it was fixed. Phrase open ones as questions about the
+   objective ("How does a first-time user find Reorder from here?"), not verdicts.
 
-## 6. Rounds and the fallback
+## 8. Lessons
 
-* At most **3 rounds** per gate. The counter is per gate, not per panel.
-* A round ends when the composite is computed.
-* Rounds 2 and 3 exist to fix what the panels found. Fix in composite-impact order: the panel with the largest `weight x (10 - score)` first.
-* **`fallbackPolicy: ship_best`.** If the third round is still below 8.0, the status is `Below threshold` and what ships is the best round, not the last one. Best = highest composite; a tie goes to the earlier round (fewer changes). A later round edited the canvas, so put the canvas back into the best round's state before handing over — undo back to it, or re-apply that round's fix list in order.
-* Ship the best round's artifact and report the failing score. `Below threshold` is a status, not a licence to hide the number.
+Ask the person with `ask_user` which findings to remember, one question per finding: for every
+project, for this project, or not. Save only what they approve, with
+`design_lessons {add: {rule, why, scope}}`: the rule is one line written as an instruction
+("Screens keep their device height; the main column scrolls"), `why` is what went wrong. Never
+save a lesson the person did not approve, and never save praise. Lessons come back in
+`get_basic_info` and in the next `critique_design`; `design_lessons {remove: "L3"}` drops one.
 
-## 7. Status vocabulary
+## Sources
 
-Every gate ends with exactly one status.
-
-| Status | When | What ships |
-|---|---|---|
-| `Shipped` | composite ≥ 8.0 | the reviewed artifact, unchanged |
-| `Below threshold` | still < 8.0 after round 3 | the best-scoring round's artifact (`ship_best`), with the score reported |
-| `Timed out` | the gate ran out of its budget (rounds or minutes) before a verdict | the best round so far, with the timeout stated |
-| `Interrupted` | the user or the session stopped the gate mid-run | the last complete round's artifact |
-| `Degraded` | a panel could not be judged properly (section 8) | the artifact, but the verdict is provisional and the reason is named |
-
-`Degraded` outranks `Shipped`: a degraded panel is capped at 6.9, so a degraded run reports `Degraded`, not `Shipped`, even when the composite clears 8.0.
-
-## 8. Degraded reasons
-
-A panel that cannot be judged on real evidence is not scored as if it were fine. It is capped at 6.9, the composite is computed with the cap, and the run reports `Degraded` with the reason and the panel it hit.
-
-| Reason | Cause | Handling |
-|---|---|---|
-| `malformed_block` | a tool returned something the gate could not parse (lint payload in an unexpected shape, a truncated screenshot answer) | retry the tool once; if it still fails, judge the panel on the evidence you do have and name the missing part |
-| `oversize_block` | the evidence was too big to read whole (a screenshot scaled down past legibility, a tree deeper than the context, a lint payload whose `truncated` flag is set) | narrow the scope: screenshot or lint a subtree, split the screen into regions and judge region by region |
-| `adapter_unsupported` | the requested target or format is not supported here (a `verify_code` target the project does not build) | drop that check; the panel falls back to the screenshot plus the design rules |
-| `protocol_version_mismatch` | the MCP server exposes a different tool set than the gate expects (a tool renamed, an argument changed) | stop using the broken tool, finish what you can, report `Degraded`; do not guess the schema |
-| `missing_artifact` | the thing under review is gone (artboard deleted, page switched, stale node id) | re-snapshot with `get_basic_info` and restart the gate; if the artifact is truly gone, report `Degraded` |
-
-Degradation is a report, not an excuse: name the reason, the panel and the evidence you lost.
-
-## 9. What the gate reports
-
-End the gate with the status, the numbers and the findings, in that order:
-
-```
-Critique gate - Sign in (page p1, artboard 3fa9c1:7)
-Round 2 of 3 - composite 8.44 / threshold 8.00 - status Shipped
-Designer 7.5 (weight 0) | Critic 8.5 | Brand 8.5 | Accessibility 8.5 | Copy 8.2
-Composite = 8.5x0.4 + 8.5x0.2 + 8.5x0.2 + 8.2x0.2 = 8.44
-```
-
-Then, per finding: the panel, what was seen, the evidence behind it (tool and finding, or the region of the screenshot), the fix, and whether it was fixed in this round or is still open.
-
-Machine-readable form, when the caller wants JSON:
-
-```json
