+# SolidCraft: instructions for agents
 
-SolidCraft is a clean-room, open-source, pure-Rust parametric 3D CAD application:
-sketches with a constraint solver, a parametric timeline of features, a B-rep
-kernel, and a desktop UI that agents can drive. Projects published by
-[storytold](https://github.com/storytold) can serve as references for implementation conventions.
-Any code adapted from other projects (MIT OR Apache-2.0) is noted in ATTRIBUTION.md.
+SolidCraft is a clean-room, pure-Rust parametric 3D CAD app (sketch solver, feature timeline, B-rep kernel, an egui UI that agents drive). This file is a router: the hard rules, then the skill to read for your task. Humans: CONTRIBUTING.md.
 
-## Product name
-SolidCraft everywhere: crates `solidcraft-*`, binaries `solidcraft` and `solidcraft-cli`,
-`.solidcraft` designs, the `solidcraft/N` format tag, `SOLIDCRAFT_*` environment variables,
-settings and recovery folders, the MCP server name, docs, CI and packaging. The old name
-survives only in the explicit compatibility shims listed in `docs/compatibility.md`; don't add
-new uses of it anywhere else. Public docs/web/Flatpak deployments use project Pages
-`/solidcraft/`; do not add permanent old-name Pages aliases.
+## Start here
+Work: ROADMAP.md, "Where help is wanted most" in CONTRIBUTING.md, issues labelled `help wanted`, `good first issue`, `needs-triage`; architecture in `docs/architecture.md`. Act when the code, docs and rules settle a question; ask only when it changes what users see. Local `plan/` notes are optional.
 
-## Start every session here
-1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md`
-   and the relevant `plan/architecture.md` section.
-2. Kernel and library decisions: `plan/adr/0001-geometry-kernel.md` (what we may depend on, what
-   is rejected for licence reasons).
-3. Follow the autonomous operation protocol (`plan/execution-plan.md` §6). Don't stop to ask
-   unless it lists the decision as the owner's.
+## Hard rules (what enforces each)
+- Independent: never copy another product's code, icons, text or templates; never drive or take data from commercial CAD. `skills/solidcraft-ground-rules/SKILL.md`.
+- No GPL/LGPL/AGPL code, not even reading it (OpenCASCADE, FreeCAD, SolveSpace, CadQuery, LibreCAD, QCAD): `cargo xtask licences --check`.
+- Every asset is original or openly licensed with a row in ATTRIBUTION.md; read `assets/AGENTS.md` before icon work: `cargo xtask assets`, `cargo xtask icons`.
+- Never crash: no unwrap/expect/panic/unsafe in non-test code (unsafe allowlist in crash-safety), errors are `Result`, input is hostile: clippy `-D warnings`, `hostile_params_never_panic`.
+- Everything is a command and programmatic calls never open dialogs: `skills/solidcraft-commands/SKILL.md`.
+- Layering (geom, sketch/kernel/render, doc, io, engine, ui-egui, apps); only `crates/kernel` uses truck: `cargo xtask layers`.
+- One outer UI container, one camera path (`navigation::handle`), colours from theme tokens: `cargo xtask ui-containers`.
+- Application code is Rust only and builds for wasm: `cargo xtask wasm`, `cargo xtask web-offline-test`.
+- The product name is SolidCraft; the old name lives only in `docs/compatibility.md`.
+- Sorted lists (message catalogs, `mod` lines, languages) stay sorted: `cargo xtask lists`. Never edit generated files (`docs/features.md`, `THIRD-PARTY-LICENSES.txt`) in a PR.
+- A design-format change is ONE new file in `crates/doc/src/format/pending/`: `scripts/test-format-pending.sh`.
+- A command has input and output schemas (will become required; `schema/unconverted.txt` only shrinks): `skills/solidcraft-commands/SKILL.md`.
+- New UI strings go in `assets/locales/pending/<slug>.json`, ATTRIBUTION rows in `attribution/pending/<slug>.md`: `cargo xtask lists`.
+- A changed default keeps the old behaviour behind a preference and fills the PR's `Changes a default:` line, and no second PR for an issue a lower-numbered one closes: `pr-checks.yml`.
+- A regression test goes in the area's existing test file, never a per-bug file (#3226).
+- Look at open PRs first, claim with a draft PR (lowest number wins), one topic per PR, never force-push `main`, no pushes just to catch up with `main`: `skills/solidcraft-contributing/SKILL.md`.
+- Show observable changes with real screenshots or a recording, captured yourself.
+- Run `cargo xtask ci` before every commit, without switching branches while it runs. `cargo xtask skills` keeps this file and `skills/` honest.
 
-`plan/` is gitignored (local only).

-## Never crash
-People trust SolidCraft with their designs; a crash loses their work. **This outranks feature work.**
-- **No panics in non-test code:** no `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!`,
-  `unimplemented!`; no `unsafe` (`unsafe_code = "forbid"`). The exceptions, in the app crate and in
-  `crates/threedx-client` (which deny it instead), have no safe API: the macOS-only
-  `crates/threedx-client/src/macos.rs` (loads the 3Dconnexion driver's client framework at run time
-  and calls through its function pointers), two functions in
-  `apps/solidcraft/src/open_documents.rs` (macOS hands Finder files only to an Objective-C
-  method), the Windows-only `apps/solidcraft/src/native_crash.rs` (the exception filter that
-  records crashes inside native code such as graphics drivers) and the Windows-only
-  `apps/solidcraft/src/native_frame.rs` (the window procedure that answers the resize-border hit
-  test of the window without OS decorations).
-- **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature
-  returns an error ("not supported yet: …"); it never panics.
-- **Input-derived numbers are hostile** (command parameters, design files, control-channel
-  input): `get()` not `[i]`, finite checks, caps on sizes and loop counts.
-- **Third-party kernel calls are guarded:** everything that calls `truck` goes through
-  `solidcraft_kernel::guard`, which turns a panic into `KernelError::Internal`.
-- **Last-resort guard:** `Session::execute` runs every command under `catch_unwind`; an escaped
-  panic restores the design and reports `EngineError::Internal`.
-- **Crash reports:** the desktop app writes every panic and every unclean exit to a local crash folder,
-  with the design and the commands that reproduce it (`solidcraft_engine::crash`, docs/crash-reports.md).
-  When someone says the app crashed, look there first: `solidcraft-cli crashes`, `crashes show <id>`,
-  `crashes replay <id>` (or the `diagnostics.crash_reports` command / MCP `crash_reports` tool).
-- **Prove it:** every crash fix lands with a regression test (see `hostile_params_never_panic`); a
-  crash report's `design.solidcraft` + `replay.json` is the test's starting point.
-- **Where tests go:** a regression test goes into the existing test file for its area (booleans, blends,
-  shell, sweep, STEP, naming…), never a new file named after the bug (#3226).
-- Every production crate root carries
-  `#![deny(clippy::unwrap_used, clippy::expect_used, clippy::panic, clippy::unimplemented, clippy::todo, clippy::unreachable)]`.
-
-## Non-negotiables
-- **Independent.** SolidCraft is independent. Behaviour is designed from public documentation,
-  general CAD conventions and user feedback. Reference tests use analytic values and open-source
-  tools. Never copy another product's code, icons, artwork, help text, tooltips, templates or
-  materials. File formats come from public specifications.
-- **No commercial CAD products.** Agents must not drive, script, automate or extract data from
-  commercial CAD products (Fusion, SolidWorks, Onshape, …) for this project: no test data,
-  measurements, command lists, ids or files produced with them.
-- **Never read, copy or link GPL/LGPL/AGPL code**: OpenCASCADE, FreeCAD (incl. planegcs),
-  SolveSpace, CadQuery/OCP, LibreCAD, QCAD — don't even read their sources. (`tools/freecad-oracle/`
-  runs FreeCAD as a separate program through its public scripting API to compute reference values;
-  nothing from FreeCAD is linked, vendored or shipped.) The sketch solver and the blend
-  operations are our own.
-- **Assets — absolutely essential.** SolidCraft contains **no iconography, images, fonts or
-  artwork from commercial CAD products — ever.** Command icons are the original SVG masters in
-  `assets/icons/ui/design/svg/`, compiled through `crates/ui-egui/src/icon_svg.rs`.
-  **Before any icon, icon assignment or media edit, read `assets/AGENTS.md`,
-  `assets/icons/ui/AGENTS.md` and `assets/icons/ui/STYLE_GUIDE.md`.** Use the canonical
-  bases and named finished references there; never invent a parallel icon style. Any file asset must be original or openly licensed and **must have a row in ATTRIBUTION.md**
-  (`cargo xtask assets` enforces it). Screenshots of commercial CAD software are never committed.
-  Breaking this rule is the most serious mistake you can make in this repo.
-- **Everything is a command.** User-visible behaviour = a command in `crates/engine/src/cmd/*`
-  (`CommandSpec`: id = our own dotted, lower-case id `<area>.<thing>[.<variant>]` such as
-  `solid.extrude` or `sketch.rectangle.two_point`, never another product's command id; label;
-  toolbar tab and panel; icon; shortcut; params doc; `enabled`; JSON `run`) + tests. The toolbar,
-  dialogs, sketch tools, palette, scripts, CLI and control channel all reach the same commands.
-- **Programmatic calls never open dialogs.** `engine.execute` runs the JSON form; only toolbar
-  clicks (`ui.start`) start interactive tools and dialogs, which then run commands.
-- **Layering** is enforced by `cargo xtask layers`: L0 `geom` → L1 `sketch`, `kernel`, `render`
-  → L2 `doc` → L3 `io` → L4 `engine` → L5 `ui-egui` → apps. Nothing below L5 depends on
-  egui/eframe/winit/wgpu/rfd. **The UI crate is swappable.** Only `crates/kernel` may use `truck`.
-- **The UI is thin**: panels read engine state and act through `app.run(id, params)` /
-  `app.start(id)`. Colours come from `theme::Tokens`.
-- **One set of camera controls**: every page or canvas with a camera (viewport, Render
-  preview, future flat pattern or drawing pages) calls `navigation::handle` with its `NavCaps`
-  (orbit off for flat 2D pages). New canvases must use `navigation::handle`; never hand-roll
-  camera input (a test rejects it).
-- **Application code is Rust only.** Units are millimetres and radians internally; Z is up.
-  Local asset authoring, lint and review tools use Python 3.11+ as documented in
-  `assets/AGENTS.md`; Python is not an application runtime dependency. The application exception is
-  JavaScript the browser requires: the service worker `apps/solidcraft-web/sw.js` (browsers only
-  run service workers as JavaScript) and the small inline scripts in `apps/solidcraft-web/index.html`.
-  Keep them minimal; `cargo xtask web-offline-test` covers the service worker.
-- **Quality gates** before every commit: `cargo xtask ci` (fmt, clippy -D warnings, tests,
-  assets, layers). Commit after every feature arc that builds.
-- **Publishing**: the repository is github.com/tangency-labs/solidcraft. Changes land through
-  **pull requests** and the **merge queue**: push a branch and open a PR. The heavy CI jobs start
-  when a maintainer adds `approved-for-ci` after reviewing the code. Approved PRs go into the queue
-  with `gh pr merge N -R tangency-labs/solidcraft --squash --auto`; the queue runs the full suite
-  on each group before it lands on `main`. Keep each PR to one topic and one issue, and never
-  force-push `main`. Never commit `plan/`, build dirs (`target*/`) or generated reference data;
-  check `git ls-files` before pushing.
-- **Never break wasm**: everything below the apps must build for `wasm32-unknown-unknown`
-  (`cargo xtask wasm`, part of `cargo xtask ci`).
-
-## Showing and following through on changes
-
-- Help reviewers see what is broken or changed. For observable CAD, UI or model behavior,
-  issues and PRs must include actual descriptive screenshots or a short recording from a
-  small reproduction. This includes kernel, geometry, assembly and backend changes whose
-  effects can be shown in the app. Coding agents should run the app and capture this evidence
-  themselves; do not ask a human for evidence the agent can produce. Show the actual failure
-  or result, preferably before and after, with brief reproduction steps, expected/actual
-  behavior and annotations that point out the relevant detail.
-- Flowcharts and Mermaid diagrams cannot substitute for screenshots or recordings of visible
-  behavior. Use diagrams for architectural reasoning when actual screenshots cannot illustrate
-  the point. Changes with no useful observable behavior do not need screenshot or video evidence.
-- Use a small public-safe example and check for private designs, paths, account details or
-  other sensitive content before sharing. Attach media to the issue/PR or link to an accessible
-  recording; do not commit generated screenshots or videos just to provide review evidence.
-- Throughout the work and before handoff, check the relevant PR's merge status. Don't push to
-  an open PR only to catch up with `main` (no merge of `main`, no Update branch, no rebase for
-  that alone): every push restarts the whole CI run, and `main`'s own run catches what lands in
-  between, to be fixed forward. When you push a change anyway, or GitHub reports a conflict,
-  rebase onto the latest `main` (push your own branch with `--force-with-lease`); never merge
-  `main` into a PR. Resolve conflicts without discarding others' work; never force-push `main`.
-  Don't re-run CI on an unchanged commit: a real failure fails again. Re-run only a job that
-  runner trouble cancelled, with "Re-run failed jobs". Report the PR state you checked and any
-  conflicts resolved. If a PR remains open, keep monitoring it while the task is active and
-  make its pending status clear at handoff; do not claim it merged without checking.
-
-## Before you start: look at what is already open
-- Work with an authenticated GitHub CLI (`gh auth status`) and `git`; the checks below need both.
-- Pull the whole list, not one search: `gh pr list -R tangency-labs/solidcraft --state open --limit 500`
-  (drafts included) and `gh issue list -R tangency-labs/solidcraft --state open --limit 500`. Look for
-  work on the same issue, the same feature under another number, and PRs that change the files
-  you are about to change (`gh pr list ... --json number,title,files`).
-- If someone already has it, comment on their PR or issue instead of opening a second one. Two
-  PRs for one change can't both land, and one of them is wasted work and CI.
-
-## Claim = a draft PR
-- Before working on issue #N, check nobody has it: `gh pr list -R tangency-labs/solidcraft --state open --search "#N"`.
-- If none, branch from the latest `origin/main`, `git commit --allow-empty -m "claim: #N"`, push,
-  and open a **draft** PR titled `<summary> (#N)` right away. **The lowest-numbered open PR for an
-  issue wins**; if yours lost, close it. Opening the PR is the claim: the bot assigns you and
-  labels the issue `in progress` (or says on your PR who holds it). Reference `#N` in the PR title
-  so the bot can find it. Don't claim by editing files; comment `/claim` on the issue only to stake
-  a claim before you have a branch.
-- Push work in progress at least daily. A draft with no pushes for 72 hours may be taken over:
-  comment on it first, then open your own claim (you may start from its branch).
-  This takeover policy is separate from the bot's automatic cleanup deadlines in CONTRIBUTING.md.
-- On a shared build machine, check the load before a big build (`cut -d' ' -f1 /proc/loadavg`)
-  and wait while it is over 24; build with `nice`.
-
-## Design file format
-A change that saves something new in a design adds ONE file, `crates/doc/src/format/pending/<name>.rs`
-(a `//!` note, and `pub fn step` if older designs must be rewritten). Never edit `FORMAT`,
-`JSON_STEPS`, the history in `format.rs`, another change's file or a `v<N>/` folder: the build
-works out the number (the next one while anything is pending), and the release folds pending
-changes into `v<N>/` with `scripts/fold-format-pending.sh`. See CONTRIBUTING.md.
-
-## Application releases
-Development pushes are not application releases. Follow `docs/releasing.md` when asked to
-prepare or ship a release: choose the version from the actual changes, update Cargo.toml and
-Cargo.lock, pass the quality gates, advance `release` without force-pushing, and verify the
-resulting draft and its artifacts. When shipping is authorized, publish that verified draft
-and confirm its tag and downstream deployment. Do not auto-release every push to `main`, infer
-version bumps solely from commit prefixes, overwrite published versions, or push release tags
-before the draft is verified.
-
-## Running and looking at the app
-- `cargo run --release -p solidcraft -- --sample --control PORT` (sample design + control channel).
-  Pick a free port. Without a display, run it under `Xvfb :99` with `DISPLAY=:99`.
-- Drive it with JSON lines on `127.0.0.1:PORT` (see `docs/control-protocol.md`). The first
-  request on a connection carries the launch's token as `"token"`: read it from
-  `~/.local/share/solidcraft/control/PORT.token`, or start the app with
-  `SOLIDCRAFT_CONTROL_TOKEN=$(openssl rand -hex 32)` and send that.
-  - `{"id":1,"method":"engine.execute","params":{"command":"solid.extrude","params":{"distance":20}}}`
-  - `{"id":2,"method":"ui.start","params":{"command":"sketch.create"}}` then `ui.click {x, y}`
-  - `{"id":3,"method":"ui.screenshot","params":{"path":"/tmp/shot.png"}}` then read the PNG.
-- **For UI work, look at the result** (screenshot, read the PNG). Without a window use
-  `ui.render` or `solidcraft-cli snapshot`.
-- Headless: `solidcraft-cli run script.json --out part.step`, `solidcraft-cli eval design.solidcraft`,
-  `solidcraft-cli snapshot script.json --out shot.png`, `solidcraft-cli commands`.
-- Reference tests: `cargo xtask oracle` replays `tests/oracle/*/recipe.json` and compares with
-  each case's `expected.json` (analytic or FreeCAD values; writes `docs/oracle.md`). Expected
-  values never come from a commercial CAD product.
-- Build with `CARGO_TARGET_DIR=<repo>/target`. Windows: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
-
-## Roadmap
-`ROADMAP.md` (committed) tracks status, milestones and estimates. Update it whenever a
-milestone task lands. `docs/features.md` (SolidCraft's commands by area, from the registry) and
-`THIRD-PARTY-LICENSES.txt` are regenerated on `main` after each merge by the Generated files
-workflow; never regenerate them in a PR.
-
-## Lists many PRs add to
-Keep them conflict-free (CONTRIBUTING.md, "Lists many changes add to"): message catalogs sorted
-(`cargo xtask lists --fix`), `mod` lines in their sorted group, the language list English first
-then by id, generated files left to `main`, and a design-format change as one new file.

+The original adapters in `crates/engine/src/cmd/render/library.rs`, the generated lookup `library_data.rs` and its generator `tools/render-library/generate.py` project the already attributed starter and SELENE resources without replacing their bytes or authoring manifests. The added scalar texture channels, explicit color/V conventions and immutable-source/GPU-payload sharing are original contributor work under MIT OR Apache-2.0. No external code, commercial CAD data or new third-party imagery was imported. Source metadata and the original authoring attribution remain authoritative; pending runtime acceptance is not a photometric or engineering qualification.

 # SolidCraft roadmap
 
-Status as of **2026-10-14**. SolidCraft supports parametric modelling (sketch →
-features → parametric timeline) as an open, pure-Rust, agent-drivable application.
+The short version, for people who use SolidCraft. The detailed developer status (milestone
+tables, limitations, measurements) is in [docs/roadmap-detail.md](docs/roadmap-detail.md).
 
-## At a glance
+## What SolidCraft is
 
-| Question | Answer |
-|---|---|
-| Where are we? | **M0 and M13 done; M1, M2, M5–M7, M9, M10, M14 in progress.** Sketch with solver and the full SKETCH create/modify set; extrude, revolve (two sides, symmetric, to object), fillet/chamfer (variable radius, chord length, a radius per edge, corner patches), holes, threads (cosmetic and modelled), patterns, mirror, shell (inside/outside/both), draft, loft, sweep, coil, split body and split face, delete face, construction planes, axes and points; persistent naming of faces and edges; parameters and configurations; components, joints, motion studies, exploded views; sheet metal and a plastic enclosure subset; STEP/IGES/3MF/STL/OBJ/DXF; FreeCAD/Rhino import; autosave and crash recovery; desktop and browser (wasm) app, CLI, MCP server. |
-| Features | Every registered command by area — [docs/features.md](docs/features.md) (`cargo xtask features`); registry breadth does not establish workflow or geometric depth |
-| Reference tests | [Current case count and results](docs/oracle.md): public cases in `tests/oracle/` with analytic or FreeCAD-computed expected values, checked by the reference-test job in [CI](.github/workflows/ci.yml). |
-| Tests | Solver, profiles, kernel booleans/blends/measures, expressions, timeline, persistent naming, file formats and migrations, assemblies, sheet metal, engine end-to-end, hostile-input fuzz over every command and headless UI scenarios. `cargo xtask ci` reports the current passing counts. |
-| Gates | `cargo xtask ci`: fmt, clippy -D warnings, tests, asset attribution, layering, wasm32 build — green |
-| Time to a useful alpha (M0–M6) | ≈ **82 agent hours** remain (sum of the M1–M6 estimates below) |
+SolidCraft is open-source parametric 3D CAD written in Rust. You sketch, constrain, extrude, and
+change a parameter to watch the timeline rebuild. It runs as a desktop app and in the browser
+([try it](https://solidcraft.io/app)), and it has a command-line tool and an MCP server so that
+scripts and AI agents can drive the same commands you use.
 
-Optional GPU viewport ambient occlusion is available in View settings and Graphics preferences,
-with persistent settings, Performance/Quality graphics presets (Quality combines AO, Fine tessellation and adaptive 2× supersampling; manual combinations show Custom), and the
-`view.ambient_occlusion` and `view.graphics_preset` commands. See [display settings](docs/ambient-occlusion.md).
+## Works today
 
-## Scope (owner decision, 2026-10-07)
+- Sketching with a constraint solver, and the usual create and modify tools.
+- Extrude, revolve, loft, sweep, coil, fillet, chamfer, shell, draft, holes, threads,
+  patterns, mirror and split.
+- Parameters with units and expressions, and configurations.
+- Faces and edges keep their names through edits, so references survive changes.
+- Components, assemblies, joints, motion studies and exploded views.
+- Sheet metal with flat patterns and DXF export, and a plastic-enclosure subset.
+- A Render workspace with GPU rendering, studio lighting, materials and image export
+  (first release in 0.22.0).
+- Import and export of STEP, IGES, 3MF, STL, OBJ and DXF, and FreeCAD and Rhino files.
+- Autosave and crash recovery, and the browser build of the same app.
 
-The issue batch adds preservation of blind pockets in through cuts, associative projected
-offsets and plastic face placements, XZ (+Y normal) with a v6 migration preserving older
-designs, interactive angle placement, file-picker sketch imports, Home/recent controls,
-toolbar overflow, and the remaining component-frame and assembly WIP work. The enclosure
-acceptance scenarios now include board resizes; STEP reopening is automated. See [WIP reconciliation](docs/wip-reconciliation.md).
-Face-based Extrude Join (including outward Press Pull) now defaults to the picked body,
-so edge-touching assembly neighbours stay separate regardless of body order (#226).
+The full list of commands is in [docs/features.md](docs/features.md). Release notes for each
+version are on the [releases page](https://github.com/tangency-labs/solidcraft/releases).
 
-In scope, in priority order:
-1. SOLID and SKETCH (now).
-2. Parameters / functional constraints (done: see `parameters.*`, `expr.evaluate`; unit-aware,
-   cycles reported with their path, rename follows references, deletes list their users):
-   user parameters with units and expressions (+-*/, ^,
-   parentheses, sin/cos/sqrt/min/max/floor/ceil/round, unit conversion), model parameters
-   d1, d2… for every dimension and feature input, references between parameters with a
-   dependency graph and cycle detection, re-evaluation on change, comments, favourites,
-   CSV/JSON import and export.
-3. Components and assemblies with joints (M9).
-4. SHEET METAL: flange, contour flange, bend, unfold/refold, flat pattern with DXF export, sheet
-   metal rules (thickness, K-factor, bend radius) (M10).
-5. A small PLASTIC subset for enclosures, after sheet metal: Boss, Rib, Web, Lip/Groove, Snap Fit.
+## In progress now
 
-Deferred until further notice: MESH, FORM (T-splines), SURFACE beyond what solids need (scope proposed in #772), PCB / 3D
-PCB / Package, Render, Animation, Simulation, Manufacture/CAM, Drawings.
+Each feature below is a [milestone](https://github.com/tangency-labs/solidcraft/milestones) holding
+the issues for it, so the count shows how far along it is. Counts are as of 2026-10-25, one per
+feature or request. Work merged on a feature branch (`drawings`, `render`) counts as built but
+reaches the app only when that branch merges. They are rough, not a promise.
 
-## Milestones
+- **[Rendering & materials](https://github.com/tangency-labs/solidcraft/milestone/17)**: in progress, 9 of 34 pieces done, 3 of them built only on the `render` branch and in the app when it merges. The basic Render workspace is already in releases (0.22.0); the interface rework (#6281) and the material and light libraries are what is left.
+- **[Drawings](https://github.com/tangency-labs/solidcraft/milestone/8)**: in progress, 3 of 21 pieces built (2 in releases, 1 on the `drawings` branch), and 3 more partly built there (sheets and borders, bill-of-materials types, the paper scene). Not in the app yet: it lands when the `drawings` branch merges. Today you can export the current view as a DXF.
+- **[Sheet metal](https://github.com/tangency-labs/solidcraft/milestone/15)**: in progress, 1 of 30 requests done. Flanges, hems, unfold and flat patterns already work; the 30 are extensions, mostly the per-edge flange options (segments, miters, partial flanges, reliefs) and bend allowance.
+- **[Sketching](https://github.com/tangency-labs/solidcraft/milestone/14)**: in progress, 12 of 50 pieces done. Dimension types, selection and snapping options.
+- **[Solid modeling](https://github.com/tangency-labs/solidcraft/milestone/2)**: in progress, 9 of 50 pieces done. Blends, holes, threads and patterns.
+- **[Assemblies & joints](https://github.com/tangency-labs/solidcraft/milestone/3)**: in progress, 4 of 19 pieces done. Joints, motion studies and exploded views already work; placement rules, linked sub-assemblies, fastener stacks and weldment corners are the pieces left.
+- **[Import & export](https://github.com/tangency-labs/solidcraft/milestone/5)**: in progress, 7 of 39 pieces done. FreeCAD, SolidWorks and point-cloud import, and mesh export options.
+- **[AI agents & MCP](https://github.com/tangency-labs/solidcraft/milestone/18)**: in progress, 2 of 8 pieces done. Agent chat and the MCP server.
+- **[Interface, web app & plugins](https://github.com/tangency-labs/solidcraft/milestone/4)**: in progress, 31 of 96 pieces done. Ribbon redesign, navigation, themes, the web app and plugins.
+- **[SMLib kernel migration](https://github.com/tangency-labs/solidcraft/milestone/1)**: in progress, 1 tracking issue open. The kernel is moving from truck to NVIDIA's SMLib (usd-brep, Apache-2.0) on the `kernel-smlib` branch; it is not in releases yet. Tracked in [#4012](https://github.com/tangency-labs/solidcraft/issues/4012).
 
-| # | Milestone | Status | Hours left |
-|---|---|---|---|
-| M0 | Vertical slice | done | — |
-| M1 | Sketch depth: command coverage implemented — projection/intersect/include as linked geometry (auto-project on faces, lost-reference warnings, break link), full SKETCH create/modify set (slots, polygons, tangent arcs/circles, ellipse, fit/control splines, conic, text, trim/extend/break, fillet/chamfer, offset, mirror, patterns, move/scale, blend curve, centerline), constraints incl. curvature and polygon with over-constraint refusal, Shift-picked line midpoints in Horizontal/Vertical using persisted points and ordinary constraints (#2087), driven/arc-length/linear-diameter dimensions, AutoConstrain, DXF/SVG insert, 3D sketch curves (Project To Surface, Intersection Curve, Isoparametric Curve, Spun Profile), exact free-form profiles (B-spline/NURBS edges, any spline degree, curves cut by crossings), sweeps and pipes along 3D sketch curves, canvases and decals, curvature combs. Exact free-form Extend and certified associative offsets now preserve geometry and IDs through edits, deletion and reopen. Occurrence-frame 3D wires now store explicit coordinate spaces and retain points and analytic fits through moves, refresh, undo and reopen. Constructive sketch solving (Owen 1991, Fudos & Hoffmann 1997) ahead of the numerical solver: points and rigid clusters are placed on the branch the sketch had, so dimension edits and drags keep their solution; edits that would turn a sketch over are refused; drags re-solve only the sketch per frame. Remaining workflow repairs: mixed offset junctions, legacy natural-spline seams, and damaged legacy wire links lacking frame provenance | in progress | 4 |
-| M2 | Robust modelling: coplanar booleans in the kernel, holes (placed on faces and on sketch points), threads (cosmetic, then modelled), patterns, mirror, shell, draft, split, construction geometry | in progress | 16 |
-| M3 | General fillets and chamfers (curved edges, chains, vertex blends); saddle rolling-ball surfaces now use continuous seam sections and arc-length fitting with shared contact boundaries and bounded accuracy checks; tiny rim edges remain selected instead of nearby wall seams when filleting (#2498) | in progress | 30 |
-| M4 | Files: STEP import (done — [docs/step-import.md](docs/step-import.md)), FreeCAD/Rhino solids through cadmpeg (done, desktop and CLI), 3MF export and 3MF/STL import as mesh bodies (done), 3MF with B-rep face tags ([docs/formats/3mf-face-tags.md](docs/formats/3mf-face-tags.md), done), constant-section parametric mesh reconstruction, DXF sketches, OBJ import | in progress | 6 |
-| M5 | Persistent naming of faces and edges (docs/book/src/dev/naming.md): faces named from their exact kernel-reported history (sketch curve sides, caps, revolve sections, primitive sides, blends, shell inner walls, pattern/mirror copies; split pieces told apart by the faces around them, lumps of a cut body named after their faces), edges by their faces; fillets/chamfers, sketches on faces, shell/draft/offset/replace faces, hole placements, joint origins and face appearances resolve by name first and warn when the entity split or vanished: done. sheet metal edges by base sketch line and flange side, shell inner faces, sweep and loft roles: done. kernel-reported face history: done (merged faces answer to every name; operations without history yet fall back to geometric names, flagged unverified; format 14 keeps older designs' geometric names). Left: history through sheet metal, plastic, surface and emboss features; FaceSource certificates through history | in progress | 20 |
-| M6 | UI depth: selection feedback and origin (done), timeline editing (done: hover and selection highlight modifier faces, including fillets and chamfers; edit feature, history marker drag, dependency-checked single and multi-item reorder, suppress, rename, delete with dependents, re-resolved references; redefining selections refreshes persistent edge/face references while retaining feature identity and dimension names; optional compact named left feature history with rollback bar, multi-selection and persistent folders above the parts browser), right-docked dialogs (done), live previews for every feature dialog (done), keyboard-first commands with on-canvas value boxes and sketch inline dimensions (done), drag manipulators with automatic join/cut (done: extrude incl. two sides, fillet, shell, hole depth, move, pattern spacing, revolve rotator, extrude taper), dark theme (done), right-click menu with Repeat (done), measure tool (done), section analysis (done), selection filter (done), drag-solve of sketch points (done); appearance controls now preserve body/face/component targeting, named transparent looks, reuse/search and override removal; preferences | in progress | 6 |
-| M7 | Thin extrude (walls along open or closed curves: centre, inside, outside or two sides; mitred corners, crossing walls joined; #721), sweep, loft (incl. to a point), rib and web (to next / depth), emboss (planar faces and exact radial emboss/deboss of bounded orthogonal profiles on complete exterior cylinders/sleeves), thread (cosmetic, and modelled M3–M20 outside and inside: the ISO profile screwed in as a faceted cut), coil (smooth B-spline helical walls), pipe, pattern on path, patterns of bodies and components, replace face (parallel), align, remove, feature copy/paste: done. Unique eligible cylindrical targets are inferred for new Emboss features. Left: general curved-face emboss and exact (unfaceted) modelled threads | in progress | 12 |
-| M8 | Surface workspace (#772). Done: Patch (sketch regions; edge loops filled G0, plus `crown`), Stitch, Thicken (planes and cylinders), Extend (straight edges of planar surfaces), Trim (by a plane, a face or sketch curves swept onto the surface, keeping a side or the picked regions; mutual trim of two surfaces, extended to meet and stitched, #767), Delete Face (healing), Boundary Fill, zebra/draft/curvature-map analysis, Surface Extrude/Revolve/Sweep/Loft from open and closed curves, Offset, Unstitch and Reverse Normal; the continuity-driven core (`kernel/src/bridge.rs`, G0–G3 Hermite rows) with **Blend** (`surface.blend`, #764: edge chains along one or several faces, closed rims paired seam to seam or from picked seams, a dialog), **Match** (`surface.match`), **Boundary** (`surface.boundary`, #763 — two sketch curves exact with G0–G3, three or four as the flat patch of their loop, and curve networks: Coons and Gordon surfaces through sketch, 3D-sketch or edge curves, a point for a three-sided side, G1/G2 against the faces along one direction's edges, joined into their body on request; G1/G2 on two sides that meet at a corner waits for the Gregory-type corner), **Fair** (`surface.fair`, CV fairing), **continuity analysis** (`inspect.continuity`, #770; a toolbar tool with edge markers and a legend, and curvature combs along face isocurves) and a multi-section **loft** with per-end continuity and crown, and guide rails on solid and surface lofts (one or two, scaling or stretching the sections between; #201). Also in the Class-A pass: G1…G4 blend curves in the sketch, chord and variable-radius fillets on curved edges (with honest refusals where the fit cannot hold), and a G2 corner patch where filleted edges meet (kernel; the command refuses until the patch's sections can be sewn to the blends' contacts). Left: bias/form-factor fillet sections (design recorded), a Gregory-type corner, surface Fillet between separate surface bodies (#769), Ruled (#762), Untrim (#761), curved-face Extend (#760), and every remaining #757–#772 item | deferred | — |
-| M9 | Components and assemblies: New Component / Create Components from Bodies, active component, per-component origin/bodies/sketches/timeline entries, occurrences with transforms, Copy/Paste vs Paste New, nested Browser tree with visibility and isolate; Ground, Move/Copy of occurrences, joints (rigid, revolute, slider, cylindrical, pin-slot, planar, ball) by joint origins with limits and Drive Joints, closed kinematic loops (four-bar, slider-crank: the loop's other joints follow the driven one on its branch, and driving stops where a loop can no longer close), cams (`joint.cam`: a revolute cam drives a slider or revolute follower along a closed sketch profile or the cam's edges, knife, roller or flat followers, worked out again when the profile changes; drives, studies, closed loops, contact sets), As-built Joint, Rigid Group, Contact Sets (driving and motion studies stop where bodies in a set would pass through each other), Motion Study (joint values keyed along a timeline, playback, export of occurrence positions as JSON/CSV), motion analysis (joint values and a point's path charted over a study as value, velocity and acceleration; the parts that collide along a study, with the steps where they do), Exploded views (automatic or by hand, shown without changing placements); interference, per-component physical properties; STEP with assembly structure; URDF export for robot simulators (links with meshes, mass and inertia; joint chains whose values match Drive Joints; docs/urdf.md). Physical properties now measure material-aware component/occurrence placements, descendants and repeated instances, including pending moves and body reassignment offsets; contact geometry and automatic exploded centres respect those offsets. Groundwork done: component tree, occurrences with transforms (instances, Paste New), world placement, active component as authoring frame, ground, Capture/Revert Position, moving bodies and sketches. UI: ASSEMBLE panel dialogs for New Component, Joint (snaps on faces, edges, circles and vertices; animated motion preview; offsets, flip, limits), As-built Joint, Joint Origin, Rigid Group, Drive Joints (live slider), Motion Link, Cam and Interference (overlaps shown red); joints in the timeline and the Browser | in progress | 32 |
-| M10 | Sheet metal: flange (base, edge, contour), hem, unfold/refold, convert, flat pattern + DXF, rules: done. PLASTIC enclosure subset: Boss, Rib, Web, Lip/Groove, Snap Fit, Rest, Plastic Rules (library, edit, assign; rule draft and clearance as feature defaults): done, tested against hand-computed geometry. UI: SHEET METAL and PLASTIC tabs with dialogs (live preview, Edit Feature, pre-selection) for Flange, Hem, Unfold/Refold, Convert, Sheet Metal Rules, Create Flat Pattern (flat view with bend lines, bend table CSV/JSON and DXF export with exact circle/arc/line cutouts), Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Fold (bend along a sketch line); flanges meeting at a corner closed at any angle with the rule's gap; edge flanges with their own angle and height per edge in one feature; corner reliefs (notch, round, rectangular, tear) chosen by the rule; Convert to Sheet Metal from a solid or shelled body by its bend edges (flat faces, sharp bends) | in progress | 36 |
-| M11 | 2D drawings | deferred | — |
-| M12 | Release: cross-platform packages, verification and deliberate publication implemented; original current-UI demo refreshed. Trusted distribution signing and broader performance work remain | in progress | 16 |
-| M14 | Configurations: a table of rows (parameter expressions and feature suppressions per row) switched with config.activate (undoable, all or nothing), kept through parameter renames and feature deletes (config.configure, config.table, config.column/row/activate). Per-row body materials and appearances (library looks, custom colour/opacity and clearing overrides), undoable activation and save/reopen: done. Ordered typed configuration rules, atomic validation and structured rule editing: done. Component appearance and certified semantic face style columns, atomic preview/apply and independent-copy remapping: done. Exact constructed sketch-side and immutable imported-face lineage now preserve legacy names and reject retargeting. Left: ambiguous shifted/two-sided caps | in progress | 4 |
-| M13 | Never lose work: atomic saves (temporary file, flush, rename; a crash at any moment leaves the old file or the new one) with the replaced version kept as `<file>.bak`; autosave of unsaved changes to the recovery folder every 5 minutes (preference) and after big operations, only when something changed; "Recover unsaved design?" on the next launch (`doc.recovery_list`, `doc.recover`, `doc.recovery_discard`); a kill-mid-save test (process killed while saving a 0.5 MB design 25 times). File format: `"format": "solidcraft/12"`, older formats upgraded step by step (`doc::format`), newer ones refused with a message, out-of-range numbers and broken placements refused; a corpus of designs saved by M0, components-era, joints-era and current builds (apps/solidcraft-cli/tests/corpus) that must open and evaluate as saved; damaged and hostile variants (truncation, bit flips, hostile values, removed keys, repeated features, deep nesting) never panic | done | 6 |
+## Next
 
-M6 navigation preferences include **Touchpad**: Shift + pointer movement pans, Alt/Option +
-pointer movement orbits without a mouse button, and vertical scrolling zooms. Other presets
-retain their saved two-finger scroll preference; camera motion is available through
-`view.navigate` and modifier-aware `ui.move` automation.
+- **[Surfacing](https://github.com/tangency-labs/solidcraft/milestone/16)**: next, 6 of 14 pieces done. Patch, trim, blend and match exist; the rest of the surface toolset is planned.
+- **[Manufacturing / CAM](https://github.com/tangency-labs/solidcraft/milestone/9)**: next, 1 pieces tracked, none done. There is no CAM in SolidCraft yet. Send to Slicer and a first toolpath slice are in review; proposals are [#1153](https://github.com/tangency-labs/solidcraft/issues/1153) and [#1621](https://github.com/tangency-labs/solidcraft/issues/1621).
 
-M11 precursor: File → Export Current View as DXF exports shown placed bodies from the current
-camera as a 2D millimetre drawing, with hidden edges omitted or dashed. Vector occlusion splits
-partly hidden edges and includes curved silhouettes. Repeated part meshes and triangle
-hierarchies are shared; bounded desktop preparation and occlusion use up to eight workers.
-Curves are approximated; drawing sheets,
-annotations and exact projected curves remain deferred. See [view DXF](docs/view-dxf.md).
+Features are not tied to a release or a date. Work lands in the daily releases as it is finished.
+Anything without a milestone, such as bug fixes, is not a feature and is not listed here.
 
-Drawing foundations: [RFC #860](https://github.com/tangency-labs/solidcraft/issues/860)
-and the [foundation ledger](docs/drawing-foundations.md) track the bounded implementation
-packages. The first geometry increment defines validated section records in a plane-local
-frame; the ledger separates that contract from section producers and the Drawing workspace.
+## How releases work
 
-Desktop view DXF export runs in the file-operation worker with five-stage progress and
-cooperative cancellation. Curve tolerance (0.0001–1 mm, default 0.01 mm) is remembered alongside
-the hidden-edge setting. Cancelled exports preserve the model and the previous destination;
-completed drawings publish atomically. The browser still exports synchronously.
+- Releases ship daily, as numbered versions (v0.22.0, v0.22.1) with nightly pre-releases in
+  between. They are delivered through the in-app updater.
+- SolidCraft tells you when a newer stable release exists and never updates without asking.
+  Where it can replace itself safely (AppImage, Windows installer and portable builds) there is
+  an **Update now** button; downloads are checked against the release's SHA-256 list. See
+  [updates and privacy](docs/book/src/guide/updates.md).
+- Design files carry a format number. A new version opens designs from older versions, but an
+  older version refuses a design saved by a newer one (0.22.0 writes format 35, and 0.21.0 and
+  earlier will not open it). Each release's notes say when the format changed. Keep a copy of
+  an important design before you move to a new version.
 
-## Interactive modelling
+## Licence
 
-- Modelled threads preview their cut before OK using the background worker on desktop.
-  Browser users apply the cut with OK to avoid blocking on every edit.
+SolidCraft is licensed MIT OR Apache-2.0, at your option; see [LICENSE-MIT](LICENSE-MIT) and
+[LICENSE-APACHE](LICENSE-APACHE). Versions already released stay available under those licences
+permanently.
 
-- Thread resolves a suggested metric size when a cylindrical face is picked. Diameter and
-  pitch selectors expose the existing metric designation parameter; custom designations stay
-  editable, and Automatic size returns to the face's suggestion. Cosmetic/modelled and
-  full/partial-length options remain available. This does not add tolerance classes or
-  left-hand threads.
-- New Body extrusion and face-offset previews show completed intermediate geometry while a
-  drag continues, then catch up to the exact final value. Changes to the selected geometry,
-  operation or feature still discard obsolete results. Distance arrows and their value boxes
-  follow the current frame's input.
-- Large fine modelled threads use pitch-based helix resolution and tighter faceted
-  reconstruction fallbacks, preserving thin crests and closed shells on large shafts.
+## How to follow along
 
-## Physical material data
-
-- Physical material card validation (#923/#922) provides typed SI mechanical and
-  thermal data, per-property sources/conditions and isotropic/orthotropic stability
-  checks through read-only `material.properties.validate`. It does not assign or
-  persist properties, provide a solver or enable rendering; see
-  [the contract and staged follow-ups](docs/physical-material-cards.md).
-
-- Directional elasticity (#994) queries the validated card in material-local axes
-  through read-only `material.properties.directional`, with source/condition review.
-  It does not assign body frames, predict structural behavior or enable a solver.
-
-## Library foundations (#785, #786, #787)
-
-- Local scalar libraries (#846) inspect/export bounded portable catalogs and copy exact
-  selected appearance/material revisions into existing design definitions in one undo step.
-  Appearance offers local loading/search/export; physical materials use existing commands.
-  This slice is independent of the render stack and does not change the document format.
-  See [the contract and limits](docs/book/src/dev/local-libraries.md).
-
-- Proposed phases cover offline bundled/project/user packs, physical materials and
-  appearances, editable wood mapping, and parameterized component/assembly families.
-  Stable identity/revision, copied design definitions, provenance and resource limits
-  apply from the first implementation. Existing material, appearance and standard-part
-  commands remain the application paths. See [the proposal](docs/book/src/dev/libraries.md)
-  for source/license review and acceptance gates. This is planning only: pack loading,
-  texture rendering and expanded component families are not implemented by this entry.
-
-## Render foundation
-
-- Explicit texture normalization (#1218) produces completed float RGBA with
-  role-aware linear color/data semantics, bounded matrix/TRC ICC conversion and
-  opt-in EXIF orientation. It retains high-precision raw samples and records lossy
-  gamut clipping only when explicitly requested. It is not a renderer/resource
-  consumer; see [the supported policy and limits](docs/render-texture-normalization.md).
-
-- Opt-in opaque PBR (#1046) connects persisted surface parameters to the integrated
-  product viewport and CPU PNG, using a fixed direct-light studio. Geometry and mass
-  stay unchanged. HDRI, transmission and textures remain separate gates.
-  See [the consumer and limitations](docs/render-opaque-pbr.md).
-
-- Combined integration is tracked in #842, with independent scalar libraries in
-  #863 and richer PBR/material-card transport in #1086. See [phase boundaries and validation gates](docs/render-integration.md).
-  Render/library consumers use the merged asynchronous picker (#1127). Material-card
-  UI (#1094), texture mapping and HDRI lighting remain explicit follow-ups.
-
-- R4a adds bounded CPU product-image jobs, cancellation and atomic PNG export through
-  engine commands, the Render panel, CLI and persistent MCP. Immutable captures and
-  results stay outside persistence/undo; native workers and cooperative browser tasks
-  share the same work protocol. See [jobs, limits and export](docs/render-jobs.md).
-
-- R3 adds an overlay-free product scene and the integrated Render workspace, with
-  runtime GPU host capabilities, per-document drafts and named camera/background
-  controls. Design keeps its camera and drawing policy. Raster transparency remains
-  approximate; PBR and environments are later slices. See
-  [workspace and scene contracts](docs/render-workspace.md).
-
-- R2 adds bounded named render setups in document format 21 and the read/save
-  `render.settings.get/set` commands. Proven render-only changes preserve geometry
-  and prepared world data through undo/redo and checkpoint restore. This slice does
-  not add a Render workspace, PBR, environments or image jobs; see
-  [settings and refresh policy](docs/render-settings.md).
-- Bounded PNG/JPEG texture admission (#900) validates in-memory sources and returns
-  completed RGBA8 pixels with explicit color/data roles. It is an input utility only:
-  ICC/16-bit normalization, local wood mapping, resource persistence and the renderer
-  consumer remain separate work. See [limits and licensed-file probes](docs/render-texture-input.md).
-
-- The initial opaque surface numerical contract for #1004 provides bounded linear
-  color/metallic/roughness/IOR admission and an original tested direct-light BRDF.
-  The numerical module alone advertises no capabilities; the installed consumer above
-  provides rendering. See
-  [the model, evidence and remaining consumer gates](docs/render-surface.md).
-
-- A bounded cooperative Radiance RGBE input utility is available in L1 render;
-  it does not yet enable HDRI/PBR rendering or a document import command. See
-  [the input contract](docs/render-hdr-input.md) and #813 for integration work.
-- R1 adds renderer-independent backend/profile metadata, strict request resolution and
-  bounded image/scratch admission checks, exposed by the read-only `render.backends`
-  command. It describes the current CPU raster snapshot path without evaluating the model.
-  The legacy Design snapshot route remains unchanged. Later slices above provide the
-  workspace/jobs and opaque PBR; HDRI and optional engines remain future work. See [the contract](docs/render-backends.md)
-  and [the phased proposal (#620)](https://github.com/bherbruck/solidcraft/issues/620).
-
-## Dimensioning and error reporting
-
-- MCP `execute` accepts `verbose: false`, sharing the compact reply helper used by
-  `batch`: body changes and created sketch IDs stay, while repeated lists are omitted.
-  Both tools retain full replies by default.
-
-- Sketch Create groups drawing variants under Line, Rectangle, Circle, Arc, Slot,
-  Polygon and Spline. Each open part remembers its last interactive choice per family
-  across sketch sessions and document-tab switches; closing the part resets these UI choices.
-- Inscribed, circumscribed and edge polygon tools preview their actual outline before
-  placement, including orientation and the selected side count.
-- Construction (X) preserves the active sketch drawing tool, picked anchors and inline
-  dimension values, so line type can change while a shape is in progress.
-- Planar sketch construction previews and hover feedback keep the same dashed pattern as
-  committed geometry; centerlines retain their dash-dot pattern.
-
-- Point has a default Sketch CREATE toolbar button alongside the existing drawing tools.
-  Saved custom layouts are preserved; Reset Toolbar restores the default Point button.
-- Construction planes cannot take an origin-plane name (XY, XZ, YZ, Top, Front, Right). Plane
-  arguments reject such a name when an older design's construction plane already has it. Use
-  the other alias, the construction feature's numeric ID or an explicit plane; existing
-  stored references keep their saved meaning. Section Analysis uses the same check.
-- Sketch text can be edited from a letter interior or outline's context menu or the Edit Text command.
-  Interior selection requires every profile boundary to belong to the same text source;
-  the editor highlights the whole source without replacing profile selections.
-  Content, baseline X/Y, height and rotation update the original text source in one undo step;
-  cancelling or rejecting an invalid value preserves the sketch. Position and height fields
-  use the document units captured when editing starts; generated outlines remain associated
-  with their text source, and untouched inputs preserve their saved internal values.
-  Dragging a text outline moves the entire source in one undo step; Escape restores the
-  gesture. Move/Copy on a selected text outline provides unit-aware X/Y distances and rotation
-  about its baseline; copies keep an independent editable text source.
-- Repeating the initial point of a planar multi-point sketch drawing tool is neutral: the tool
-  waits for a distinct point without a degenerate-shape error or history entry. Typed input
-  and programmatic commands retain their validation.
-- Circular-pattern and angled-plane axes reject explicitly supplied malformed or expression
-  origins instead of silently rotating about zero. Numeric origins remain in millimetres;
-  associative axis expressions and construction-axis references remain unsupported.
-- Single-line and rectangle-side dimensioning supports selecting a line or its two endpoints.
-  Type a value and press Enter to commit one undo step; rejected values remain editable and
-  cancellation leaves the sketch unchanged. Fit keeps geometry clear of the Sketch Palette
-  and navigation controls, including enlarged displays and nested pending placements.
-- Sketch Dimension takes a line and a circle or arc (#1803): it measures from the line to the
-  circle's edge (the gap, 0 when tangent, or how far the edge reaches past a line that cuts
-  it), drives it like any other dimension and keeps the circle on its side of the line.
-- Sketch annotations, live drawing lengths and Measure use document units. Inches show
-  three decimals and retain a meaningful fourth digit. Bare length dimension entry captures
-  the current design unit; changing units leaves existing geometry and expressions intact.
-  Component/canvas distance controls, sketch cursor coordinates, flat-pattern dimensions
-  and pocket depths, interference volumes and parts-library lengths also use design units.
-- Curvature and Polygon constraints accept complete preselected operands. Fix/Unfix
-  consumes complete point/curve selections consistently; mixed or ambiguous selections
-  retain the picking workflow. Rejected constraints preserve selection and undo history.
-- Contextual error reporting: a **Create Issue** action beside feature errors opens a
-  reviewable GitHub issue draft with the error, operation settings, build diagnostics and
-  useful reproduction context. The draft is editable, with optional capture of the actual
-  viewport and copy/save controls. Opening GitHub does not submit the issue. Help also exposes
-  reporting for unexpected results that did not produce an error.
-- The header exposes **Report a bug**, including an accessible compact control on
-  narrow windows. It opens the same editable report and screenshot review without
-  changing the active model or a pending dimension.
-- Crash reports: every panic (in a command, in the kernel, anywhere else) and every unclean
-  exit (abort, stack overflow, kill: found at the next start through a locked per-run command
-  journal) leaves a local report with the backtrace, version and commit, the command and the
-  design that reproduce it (`solidcraft-cli crashes replay <id>`). Repeats are counted, not
-  rewritten; at most 20 reports, 50 MB and 90 days. The app shows them after a crash (Help >
-  Crash Reports…) with a reviewed issue draft; agents read them through
-  `diagnostics.crash_reports`, the MCP `crash_reports` tool or the CLI. Nothing is sent
-  anywhere. See [crash reports](docs/crash-reports.md).
-- Agent chat (off by default, desktop): a side panel that drives a coding agent the user
-  already has (Claude Code through its ACP adapter, Codex, Gemini CLI, OpenCode, Grok Build, …) over the
-  Agent Client Protocol, under the user's own login; SolidCraft stores no keys. The agent works
-  through SolidCraft's MCP tools on a gated endpoint of its own: file actions wait for Allow or
-  Deny, crash reports are off limits, 24 changes per message, one undo step per message, and
-  the agent's whole process group ends with the panel or the app. Docks left or right,
-  minimises to a strip. Grok Build discovery includes `~/.grok/bin` and reuses the user's
-  Grok login. See [agent chat](docs/agent-chat.md).
-- Command scripts from designs (#886): `timeline.export_script` (CLI `solidcraft-cli script`)
-  writes a design's history as a script that `eval` and `run` replay into the same design —
-  user parameters, units, sheet metal and plastic rules and materials as their own commands,
-  then each feature through `timeline.add` with its ids, names and dimension parameters kept,
-  so every feature kind replays exactly and a failing feature fails the same way. Trimming the
-  script after a step gives the design at that step. Appearances, folders, views and
-  configurations are listed as left out; components and joints are not supported yet.
-
-## 0.2.0 release batch
-
-- Includes the new axis navigation, adaptive sketch drawing/picking, origin-corner repairs,
-  durable supported profile/face references, endpoint dimensioning and contextual reporting.
-- Smooth ruled-wall display joins are hidden only within the supported geometric certificate;
-  authored splits and actual creases remain protected. Wireframe retains physical edges.
-- Paste New uses a bounded current-geometry comparison for supported convex line/circle
-  prisms with separated circular holes; unsupported shapes retain the existing strict check.
-- Common-bore Union retries check additional boundary curves before recutting the bore,
-  preventing the reproduced thin-web loss. Unknown additional trims refuse; inherited
-  common-cylinder trims retain their existing policy, so this is not a general Boolean proof.
-- Exact full-path assembly joint editing remains separate work and is not part of this batch.
-- Stable 0.2.0 is published: all release payload checksums, native cold reopening, deployed
-  web app and both Flatpak architectures were verified. The replacement README demo uses
-  the original electronics enclosure story and animated pointer in the actual English
-  0.2.0 UI, at 4× playback. Publication follows [the release workflow](docs/releasing.md).
-
-## 0.2.1 critical fixes
-
-- Separated multi-profile Join/Cut extrusions into one solid target batch their tools using
-  conservative construction bounds, avoiding a Boolean rebuild for every profile. Live
-  extrusion previews build only their tools; confirmation validates the final Boolean.
-- Coplanar selected body faces share one linked sketch and one extrusion. Automatic Join/Cut
-  keeps the evaluator's participant scope, including parts of an empty imported component. Desktop OK/Enter
-  computes on a scratch session in the background, with atomic acceptance and cancellation.
-  Planar section stitching projects lines/arcs analytically and removes duplicate endpoints.
-- Imported rotated face groups can check all full start-face seams in one guarded
-  construction. Separated tools may batch a Join when each meets the same single body;
-  nearby uninvolved bodies retain the original contact decisions. Regression comparisons
-  cover all four extrusion operations.
-- Inward multi-face cuts retain every eligible target and subtract separated tools together.
-  Safe interior classification handles roundoff at shared imported line/arc endpoints.
-  Straight extrusion feedback caches existing face/profile triangles and updates the display
-  directly, including a newly opened STEP's single identity component placement; other
-  extents, moved or repeated components and curved sketch profiles keep the Engine preview.
-- The extrusion fixes retain tracked Boolean history and the current `solidcraft` packages.
-  Confirmation and tool previews use main's shared background calculation. Main's collapsed
-  blend-wall refusal and its tests are retained, including smaller valid radii and mirrored parts.
-- Axis view and navigation controls stay anchored to the viewport when feature dialogs or
-  the command palette open, at normal and enlarged display scales. Fit still accounts for
-  dialog coverage; covered controls do not receive clicks through dialogs.
-- Eligible planar faces survive fillet, chamfer and shell operations with exact source
-  certificates. Sketches placed directly on the enclosure wall and inner floor follow
-  width and wall changes, including after the USB cut and cold reopening.
-- Remove artificial straight-wall and rounded-corner subdivisions left by shell and
-  extrusion cuts. Identical generated wall segments span adjacent slabs as one physical
-  face, with exact full-height supports and boundary stitching. Preserve authored face
-  splits and face appearances. Permanent regressions cover material, STEP, reopening and
-  unaffected bodies across the extrusion end plane.
-- Feature dialogs use the available screen height for their fields, with OK and Cancel
-  outside the scrolling region, including enlarged display scales.
-- Design format 13 records shell-face attachments. Older designs remain readable;
-  newly saved designs require 0.2.1 or later. Ambiguous or unsupported faces still refuse
-  attachment rather than guessing a plane.
-- Saved projections from a removed strip retain their geometry and report the lost
-  reference. Explicitly reselect the wall to repair that projection.
-
-## View navigation
-
-- Desktop Ctrl/Cmd +/- and 0 change or reset the saved UI scale. The scale slider keeps
-  its layout stable during a drag and applies the selected scale on release.
-
-- OpenSCAD navigation preset: left drag orbits, right/middle drag pans, Shift+right/middle
-  drag zooms, and the wheel zooms. Available in the shared desktop/web Navigation preferences.
-- Compact clickable signed X/Y/Z axis tips, smooth drag-to-orbit, and Shift-orbit snapping
-  to 26 standard and diagonal views. Pointer motion accumulates independently of a lightly
-  damped spring, with a boundary margin to prevent flicker. Z-up/Y-up and the nearest square
-  top/bottom heading are preserved. Diagonals include 45-degree edge and isometric corner views.
-
-## Known limitations
-
-- Scheduled and manual CI scan locked dependency advisories, bans and sources with
-  cargo-deny. Vulnerabilities fail the scan; unmaintained crates warn. Local vendored
-  patches require separate upstream review because advisory databases cannot version-match
-  their path dependencies. Pull requests retain the existing licence checks.
-
-- Associative shell-face sketches require a unique certified planar source. Nested shell
-  attachments and ambiguous coincident sources remain unsupported.
-- G2 fillets: exact quintic blends of straight edges between planar faces, with one planar
-  end face at each end, including sloped ends (#2708). The UI and `solid.fillet` expose
-  `curvature` (alias `g2`); the size is an equivalent circular setback. Curved faces/edges,
-  multi-face ends and corner junctions remain unsupported.
-- Fillets and chamfers: constant, variable-radius and chord-length fillets; a radius per edge,
-  rounds next to earlier rounds of another radius, and smooth corner patches where three rounds
-  meet (a sphere for equal radii); perpendicular corner fillets after a closed ring of earlier
-  rounds preserve the ring's radii and the enclosed planar face (#1557);
-  mitres between separate rounds of the same radius keep their endpoint tangent, so a later
-  fillet can select an upright and its adjoining bottom mitre as one chain (#2422);
-  straight edges (convex or concave) between planar faces with perpendicular
-  planar end faces (equal-distance chamfers also meet sloped planar end faces, including inner
-  basin rims within the rim width); convex fillets also meet sloped planar ends and reflex
-  corners around pocket rims, with unequal wall slopes and extensions confined to the face;
-  connected equal-distance chamfers also trim each other across unequal sloped rim walls;
-  curved chamfer chains with straight planar ends can terminate across two existing planar
-  bevel faces, splitting their shared seam; picks on the same tangent chain are applied once (#1303);
-  whole smooth loops of a planar face, picked whole or by one edge (tangent
-  chain), including circles and walls at any angle (boss bases and tops, bores, pocket floors,
-  plate outlines), loops with sharp corners between straight or mixed arc/line edges (straight
-  blends meet in mitres; perpendicular curved walls use offset intersections, with D-rim removal
-  checked within 0.1% of analytic offset slices), runs of
-  neighbouring edges along a planar face's loop (two top edges of a box: mitred, ending square;
-  with the edge between them too, the corner becomes a sphere octant),
-  rounded corners rounded again (sphere octants, tori at concave corners); every edge of a
-  convex planar body or of an extruded part; fillets inside patterns; closed chains of curved
-  edges between any two smooth sides (a branch pipe on a main pipe), by a rolling ball (the
-  blend a rational B-spline through exact arcs), closed or ending at planar faces square to the
-  edges, where straight or curved cap edges are trimmed to the contacts (the straight edge
-  between two overlapping extruded arcs); knife edges, where the two faces have opposite
-  normals (a wall that runs out tangent into a face: the ball that fits there); an edge that
-  runs out along an end face tangent to one side (the arc top edge of that wall), cut where the
-  blend meets it; rounds that end in an earlier round on curved faces, in any order (the rounds
-  of two edges at a vertex meet in a crease, as on a box), picked together or one after the
-  other, except a round after a round of the edge between the wall and a flat face that it
-  would run over; the three edges at a vertex of any smooth faces, of one radius, end in a
-  piece of sphere. A limiting blend that collapses a side wall into coincident boundary
-  curves is refused as too large rather than returning an unmeshable face (#1113).
-- Booleans: prisms along one direction (plates with holes, slots, patterns of them, equal
-  sections stacked end to end) are combined exactly in 2D. Qualified axial cuts preserve
-  annular holes with overrun cutters, including inward Press Pull after a joined extrusion;
-  curved wall qualification rejects false transverse axes instead of filling holes.
-  Bodies touching along one whole face
-  (a part and its mirror image) are stitched; coincident planar faces are pushed apart when
-  their neighbours are planes or cylinders. Other coincident curved configurations can still
-  fail. Bounded containment classification preserves fully internal cavities and nested
-  material islands independently of shell order, with STEP round-trip and material-membership
-  regressions. Near-contact curved shells use the general boolean path rather than a
-  containment shortcut. Spheres are built from six pole-free patches.
-- Mass properties come from fine tessellation (curved faces within ~1e-4 relative); triangles
-  that cut through curved faces (trimmed faces after booleans) are split onto the surface first.
-- STEP import (our own reader, crates/kernel/src/step_in) reads solids (B-rep with analytic and B-spline geometry), units,
-  product names, colours and assemblies; analytic offsets on planes, cylinders, cones, spheres
-  and regular tori are read exactly (signed/nested distances, units and face sense). Freeform
-  offset surfaces and pcurve-only edges are not read yet,
-  and assembly components are flattened into bodies. Closed periodic faces (torus, B-spline
-  bands) are split in two for meshing; measure() uses a finer tolerance for small radii.
-- Persistent naming follows the kernel's exact face history (docs/book/src/dev/naming.md):
-  references resolve by name first, follow splits and merges, and warn when the entity split,
-  merged or vanished, or was found by geometry only (operations that report no history yet).
-  New planar sketch attachments use exact box, extrusion cap/side and immutable imported-face
-  source certificates with checked target and author occurrence paths. A missing or changed
-  source fails explicitly; Redefine Sketch Plane previews reattachment or a fixed plane while
-  retaining current geometry and dimension identities. Unsupported modified faces need an
-  explicit fixed plane. Legacy attachments retain their original resolver behavior.
-- Modelled threads are cut as a faceted body (curved faces within 1/200 of the pitch); Extrude
-  and Revolve To Object on a curved face cut the tool back to the target's surface.
-- Explicit sketch breaks preserve exact ellipses, fit/control splines (including high degrees)
-  and conics; analytic trim/break also sees free-form cutters. Free-form curves cut at a tangent
-  touch (no clean crossing) enter that profile as polylines.
-  Sweeps along 3D sketch curves follow their polyline (smooth walls when the path is smooth).
-  A sweep with a twist, an end scale or a parallel or direction orientation (#771) follows its
-  path that way too, even along sketch lines and arcs: B-spline walls through stations, ruled
-  walls through denser stations where the path has corners or the profile has holes.
-  Guide rails (one or two, #771) do the same: each station meets every rail once, and the rail
-  turns the profile and scales it (or stretches it across to the rail) against the start; two
-  rails carry it between them. Rails along a path with sharp corners are refused for now.
-- Extend intersects exact ellipses and rational/high-degree splines without moving the line or
-  circular support. Associative free-form offsets have a whole-span 0.002 mm normal-distance
-  certificate and refine within bounded node limits while retaining existing IDs.
-  At the node limit, geometric certificate subdivisions accommodate unequal spline parameter
-  speeds without changing stored nodes or relaxing the distance tolerance (#971).
-  Associated offset fit nodes stay hidden from display, picking and snapping; dragging the
-  editable source updates the derived boundary live. Break Association restores point editing.
-  Singular, self-intersecting and ambiguous curves refuse atomically; mixed junctions and nonsmooth
-  closed natural-spline seams remain limitations. New explicitly closed fit splines and closed
-  offset outputs use periodic C2 interpolation, supporting repeated certified offsets; older
-  natural splines are preserved. Clicking the starting fit point deliberately closes a new loop.
-  Newly captured adaptive profile references with complete source coverage retain their outer
-  and hole identities through span-count changes, including parameter edits after extrusion.
-  Partial, intersected or ambiguous boundaries do not qualify for these whole-source references.
-  Legacy curve-span multisets remain exact and unchanged; already-lost selections may need
-  reselection. Format 12 stores the new bounded whole-boundary references.
-  Projected analytic boundaries follow nested loop identities through resizing, including
-  stationary holes and rounded corners. Supported convex, tangent line-and-arc boundaries
-  can lose or regain corner arcs during an inset while preserving reserved curve identities
-  and linked profile selections. Format 12 saves those associations; compatible older closed
-  offsets upgrade structurally without changing their curve IDs. Breaking an association
-  freezes its current boundary and materializes downstream profile references. Child offsets
-  of a boundary with retired arcs still require breaking its association first; mixed or
-  nonconvex junctions and retained references to disappearing individual arcs remain limited.
-- Extrude and Revolve editors retain original direction, extent expressions, explicit targets,
-  axes, From/To inputs and All-profile intent. No-op edits preserve downstream dimension names
-  and selected occurrence frames; cancel and successful edits preserve one-step undo history.
-  Placed feature edits preview through the edited timeline entry, and cylindrical Emboss guides
-  use the sketch's actual target, author or uniquely placed third-component frame.
-  Revolve rotators follow the actual signed axis and support symmetric and two-sided extents;
-  dragging a To Object extent converts its derived value to an explicit angle. Legacy reversed-axis
-  symmetric geometry is preserved through format 11's explicit legacy convention. New revolves
-  use the sketch-normal direction for each selected profile, including To Object and curved
-  target trimming, independently of the selected axis sign.
-- Cylindrical emboss/deboss wraps bounded orthogonal line profiles, including holes, concave
-  outlines and nested islands, onto complete exterior cylinders or coaxial sleeves with exact
-  radial walls. New features infer a unique eligible cylinder when the face field is empty;
-  ambiguous targets require an explicit face. Saved target
-  and author occurrence paths retain the chosen placements; missing/split faces refuse rather
-  than retarget. General free-form profiles, seams, stepped cylinders and other curved surfaces
-  remain unsupported. STEP round-trip and independent radial/volume checks cover this subset.
-- Shell and offset faces work on bodies of planes, cylinders, cones, spheres and tori (convex or not:
-  filleted boxes, bosses, domes, countersinks; corners where four or more planes meet, such as a
-  floor falling to a drain, as long as the corner's edges are all convex or all concave); draft on convex planar bodies and on walls (planes, cylinders → cones) between caps; lofts through three or more sections are smooth (B-spline sides through every section), two
-  sections ruled. Circular-meridian barrels retain curved inner walls through either axial
-  opening (#2421). Solid lofts preserve holes through sections with matching hole counts
-  (#2435), including inner walls and caps with openings; a hole cannot appear or disappear
-  between sections, and sections with holes cannot collapse to a point.
-
-- Sketch corner tools: fillet and all three chamfer modes pick a connected corner even when
-  its endpoint overlaps the fixed origin or a loose point. Ordinary drawing still snaps to
-  the origin; clicked UI regressions verify geometry, closed profiles and undo.
-- Sketch display: drawing, picking, highlighting, tool previews and profile shading share
-  adaptive projected curve boundaries. Fit, zoom, display scale and placed sketch frames
-  invalidate the display cache without changing CAD geometry or timeline history. Work
-  budgets and clipped paths prevent unbounded sampling or invented edges across the eye plane.
-  The Sketch Palette scrolls its options on short windows and enlarged displays while
-  keeping constraint status and Finish Sketch visible.
-- Face projection: closed boundaries have a deterministic outer-first order. Refresh matches
-  existing geometry before assigning positions, retaining saved curve IDs and constraints
-  across enumeration changes and resize, including concentric circles. Ambiguous identities
-  retain the last geometry and report a lost reference; permutation matching is bounded.
-- Project accepts complete supported preselection in one undo step. Visible external sketch
-  curves and points retain their source sketch identity; model geometry, axes and planes use
-  the existing linked projection commands. Rejection preserves the document and selection;
-  mixed selections retain ordinary tool-first picking.
-- Inline sketch dimensions: Tab and Shift+Tab cycle within the active shape's value boxes,
-  selecting visited values for replacement. Expression completion retains forward-Tab
-  priority; real keyboard regressions cover rectangles, lines and single-value circles.
-  Typed lengths, radii, line angles, signed arc sweeps and slot lengths persist as constraints
-  and expressions through save/reopen. Shape creation and its dimensions form one undo step;
-  rejected values keep the editable field focused.
-- Repeated components: Browser selection, visibility, properties, copy and Move/Copy use
-  checked occurrence paths. Active nested occurrences author planar sketches and solids in
-  their selected frame. Pending moves compose through parents; dialog cancellation restores
-  its selected move. Source materials and body/face appearances follow transformed instances.
-  Shared nested definitions remain shared. Deep Paste New copies reachable definition graphs,
-  independent feature/input histories, styles and internal motion records, with bounded geometry
-  checks and explicit external-link notices. Paste New selects the copy while preserving the active
-  authoring context. Imported periodic STEP seams survive placement and reexport with shared
-  topology and appearances intact. Recorded body transfers preserve historical Join/Cut membership,
-  material, placements and machining data through edits, copying, undo and reopen. New 3D wires
-  record their coordinate frame; legacy wires migrate from known provenance without changing
-  coordinates. Broken legacy links with missing provenance can require explicit refresh or relink.
-  See [occurrence workflows](docs/occurrence-workflows.md).
-- Toolbar drops on panel labels, gaps and margins append commands with insertion feedback;
-  button drops keep insert-before ordering.
-- Parameters and Configurations have distinct actions in the SOLID toolbar's CONFIGURE panel.
-  Parameters opens the user/model variable editor; Configurations opens the configuration table.
-  Configure remains available in the panel dropdown.
-- Parameter creation supports Enter with validation and continued keyboard entry. Shared
-  expression autocomplete supports Up/Down selection, Enter/Tab acceptance and Escape dismissal;
-  accepting a suggestion does not submit a parameter or trigger viewport shortcuts.
-- Movable window title bars follow the app's dark/light header palette. Radial right-click
-  menus are opt-in in Preferences > Navigation; ordinary context menus remain the default.
-- Desktop distribution: running Windows windows and executable resources use the app icon;
-  packaging validates icon resources. Nix installs launchers, MIME data and generated icons,
-  with explicit launch apps and Vulkan-loader/driver discovery. Flatpak feed instructions
-  register the required runtime source; release checks exercise desktop modelling on X11/Wayland.
-- OpenGL rendering clamps effective anti-aliasing to 1x across UI pipelines, textures and CAD
-  callbacks to prevent black frames. Other backends retain the requested sample count, and
-  stored preferences remain unchanged.
-- Configuration rules: ordered typed conditions can drive parameters and suppressions or
-  restrict values. Preview explains effective values without modifying the document; applying
-  rules validates rows atomically. Length expressions retain their authoring units across
-  document-unit changes. The UI supports structured All/Any/Not conditions and rule ordering.
-  Component styles and certified semantic face styles are available; unsupported lineage refuses
-  atomically, and stale certified face paint cannot jump to another surface. See [configurations](docs/configurations.md).
-- Sheet-metal material: inherited holes, crossing edge notches, overlapping cuts and retained
-  islands share the same boundaries in flat preview, DXF and unfolded solids. Detached material
-  pieces survive unfold/refold as one logical sheet group, including split flanged sheets.
-  Cut-outs made in the flat pattern cross bends at any angle or curved: their edges fold to
-  helices and curves on the bend, their walls square to the sheet. Free-form bases use bounded
-  sampling.
-  Parallel prismatic partial-depth cuts retain pocket side and depth through transfer and
-  unfold/refold, with separate pocket contours in preview and DXF. Planar Intersect preserves
-  exact holes and retained islands, including the union of multiple selected profiles, and
-  records complementary depth layers as pockets while retaining the stock gauge. Unsupported
-  tapered or bend-crossing machining refuses atomically instead of restoring material later.
-  Sketches attach to a sheet's flat faces (base and flanges, either side) by panel, in the
-  flat pattern's coordinates, and follow it through rebuilds and unfold/refold.
-  A flange on another flange's far edge (a return) follows that flange's closed end and keeps
-  clear of the flange beside it, and the returns of one feature are mitred toward each other
-  with the rule's gap where their flanges meet at a corner; returns of separate features, and
-  flanges on returns, are not closed toward each other.
-- Rolling-ball fillet accuracy: independent offset-cylinder tee references check surface
-  distance, actual trimmed tessellation, supporting-cylinder contacts and tangency at two
-  scales. The measured trimmed-part error is below 0.0001 mm; this is an analytic geometry
-  check. Under-resolved fits return an error.
-- Contact driving checks the trajectory between clear endpoints, including linked joints,
-  playback and sparse motion exports. Checks use bounded tessellation samples, not exact
-  continuous collision detection; local thin walls and small details remain limitations.
-  See [contact-set limits and recovery](docs/contact-sets.md).

-3D sketch drawing snaps to points on other visible sketch planes without flattening them onto
-the active plane. Bridge endpoints capture their source positions; associative endpoint links,
-construction-plane selection of 3D wires and loft guide rails remain separate work.
-Feature dialog header chevrons collapse and restore the form without discarding selections
-or edited values, including the Appearance panel.
-## Construction on 3D paths
-
-Plane Along Path has a viewport path selector, fractional position, live preview and timeline
-editing. Construction planes and points resolve drawn 3D wires without applying their sketch
-plane a second time. Curved paths use sampled segments; multi-curve chains, absolute distance
-and reference-object placement remain separate work, as do loft rails and centerlines.
-
-## Design properties (#1015)
-
-- Designs carry project, part number, revision, author, organization, description and licence
-  in an optional `metadata` object (File → Design Properties…, `document.metadata.*`,
-  `inspect_design`). STEP and IGES headers and 3MF model metadata take the fields their format
-  has a place for. Other tools keep their own data under a reverse-DNS key, kept as it is
-  through open, edit and save and never exported. See [design properties](docs/book/src/guide/files.md#design-properties).
-  Per-component properties (a part number per component) can follow with the same type.
-
-## Document-opening performance
-
-- Desktop STEP import prepares consecutive independent solids in bounded batches with up
-  to eight workers, retaining serial traversal, result order and persistent source identities.
-  The web path remains serial. Original multi-solid fixtures show 64–81% lower complete
-  import times; single-solid assembly parts are not scheduled across nodes. See
-  [measurements and limits](docs/perf.md#parallel-step-body-preparation-2026-10-12).
-- Design containers (#303, phase one) separate and deduplicate STEP, raw images and
-  lossless binary mesh arrays while keeping plain JSON as a supported Save As/export
-  format. Generated-mesh storage measurements reduce serialization and decoding work;
-  a seekable reader defers original blobs until after provisional display.
-  See [container format](docs/design-container.md) and [performance measurements](docs/perf.md).
-- Warm saves with explicit `cache: true` can include a versioned native B-rep cache through SolidCraft-owned topology
-  and geometry records, with a separate truck adapter and bounded binary reader. Exact
-  face-source certificates and operation history survive codec round trips. A provisional
-  picture can be generated before original blobs are read; editing and measurement wait
-  for authoritative reconstruction. Cached metadata binds preview and reconstruction to
-  the same document despite concurrent file writes. Default saves omit this cache and never force cold
-  evaluation or meshing; explicit `preview: true` remains a separate warm-mesh option.
-  Keys, resource budgets and document/revision guards reject incompatible, hostile or
-  stale results. A second modelling kernel still requires its own tested adapter.
-- Warm saves with explicit `cache: true` can also carry a bounded PNG thumbnail from already cached meshes.
-  Home reads it without rebuilding the design when its local picture is missing;
-  mismatched or malformed thumbnails fall back to normal generation. The image is
-  kernel-independent and saving never forces cold meshing to produce it.
-
-- Cold rebuild profiling separates parsing, geometry, placement, display meshing and
-  thumbnails. Straight-line closest-point projection and exact curved-surface evaluation
-  reuse reduce repeated work without relaxing geometry checks. Three alternating optimized
-  benchmark runs reduce median rebuild time by 26% on the public sensor enclosure and 22%
-  on a local case assembly; shape measurements and topology match the original build.
-  See [performance measurements](docs/perf.md). Further cold Boolean and import costs remain.
-- Prepared assembly geometry survives selection and view changes while real geometry and
-  placement changes invalidate it. A Pi assembly edge-selection probe drops from 9.24 s to
-  0.57 s; initial opening is unchanged. Actual Windows desktop profiling measures 15.87 s
-  median opening, with 82% spent rebuilding geometry; halving full opening remains open.
-
-## Kernel
-
-- Successful Boolean retries report their strategy and numerical adjustments as
-  feature warnings and structured inspection data. Diagnostics survive cached
-  evaluation, undo/redo and cold reopening; the robustness runner counts retry
-  events by strategy and reports any bounded-log truncation. Existing geometry
-  acceptance checks remain in force.
-
-- Cylinders of one radius whose axes cross (a second bore across a bore of the same size, a pipe
-  tee of equal pipes) touch at two points, where the mesh intersection cannot trace the curves
-  and a boolean cannot tell the four arms of the crossing apart. When the ordinary boolean fails
-  on such a pair, both faces are split along the line of their cylinder through the touching
-  points (the solids are unchanged), the boolean is taken of those, and its history is composed
-  back over the operands as given (#788). The result keeps the split lines as edges of the bore
-  walls. A crossing the ordinary route fails on and the split faces do not help (a radius of 17.5
-  in a 45 mm block with a tool of 80 mm) is still refused.
-- Boolean intersection-curve construction refuses point-only, collapsed and non-finite
-  polylines without panicking. Direct constructor regressions retain valid open endpoints
-  and closed spherical intersections; the original interactive trigger remains unidentified.
-- Shell of a stepped, joined planar body no longer creates horizontal subdivisions across
-  continuous walls. Fresh axis-aligned Cut walls are stitched using their exact construction
-  support and shared topology, preserving real steps and intentional boundaries. The local
-  reported case returns from 86 to 49 faces with unchanged material and bounds; regressions
-  cover stepped stock, STEP round trips and saved projections from removed pieces.

+ a. "Adaptation" means a work based upon the Work, or upon the Work and
+    other pre-existing works, such as a translation, adaptation,
+    derivative work, arrangement of music or other alterations of a
+    literary or artistic work, or phonogram or performance and includes
+    cinematographic adaptations or any other form in which the Work may be
+    recast, transformed, or adapted including in any form recognizably
+    derived from the original, except that a work that constitutes a
+    Collection will not be considered an Adaptation for the purpose of
+    this License. For the avoidance of doubt, where the Work is a musical
+    work, performance or phonogram, the synchronization of the Work in
+    timed-relation with a moving image ("synching") will be considered an
+    Adaptation for the purpose of this License.
+ b. "Collection" means a collection of literary or artistic works, such as
+    encyclopedias and anthologies, or performances, phonograms or
+    broadcasts, or other works or subject matter other than works listed
+    in Section 1(f) below, which, by reason of the selection and
+    arrangement of their contents, constitute intellectual creations, in
+    which the Work is included in its entirety in unmodified form along
+    with one or more other contributions, each constituting separate and
+    independent works in themselves, which together are assembled into a
+    collective whole. A work that constitutes a Collection will not be
+    considered an Adaptation (as defined above) for the purposes of this
+    License.
+ c. "Distribute" means to make available to the public the original and
+    copies of the Work or Adaptation, as appropriate, through sale or
+    other transfer of ownership.
+ d. "Licensor" means the individual, individuals, entity or entities that
+    offer(s) the Work under the terms of this License.
+ e. "Original Author" means, in the case of a literary or artistic work,
+    the individual, individuals, entity or entities who created the Work
+    or if no individual or entity can be identified, the publisher; and in
+    addition (i) in the case of a performance the actors, singers,
+    musicians, dancers, and other persons who act, sing, deliver, declaim,
+    play in, interpret or otherwise perform literary or artistic works or
+    expressions of folklore; (ii) in the case of a phonogram the producer
+    being the person or legal entity who first fixes the sounds of a
+    performance or other sounds; and, (iii) in the case of broadcasts, the
+    organization that transmits the broadcast.
+ f. "Work" means the literary and/or artistic work offered under the terms
+    of this License including without limitation any production in the
+    literary, scientific and artistic domain, whatever may be the mode or
+    form of its expression including digital form, such as a book,
+    pamphlet and other writing; a lecture, address, sermon or other work
+    of the same nature; a dramatic or dramatico-musical work; a
+    choreographic work or entertainment in dumb show; a musical
+    composition with or without words; a cinematographic work to which are
+    assimilated works expressed by a process analogous to cinematography;
+    a work of drawing, painting, architecture, sculpture, engraving or
+    lithography; a photographic work to which are assimilated works
+    expressed by a process analogous to photography; a work of applied
+    art; an illustration, map, plan, sketch or three-dimensional work
+    relative to geography, topography, architecture or science; a
+    performance; a broadcast; a phonogram; a compilation of data to the
+    extent it is protected as a copyrightable work; or a work performed by
+    a variety or circus performer to the extent it is not otherwise
+    considered a literary or artistic work.
+ g. "You" means an individual or entity exercising rights under this
+    License who has not previously violated the terms of this License with
+    respect to the Work, or who has received express permission from the
+    Licensor to exercise rights under this License despite a previous
+    violation.
+ h. "Publicly Perform" means to perform public recitations of the Work and
+    to communicate to the public those public recitations, by any means or
+    process, including by wire or wireless means or public digital
+    performances; to make available to the public Works in such a way that
+    members of the public may access these Works from a place and at a
+    place individually chosen by them; to perform the Work to the public
+    by any means or process and the communication to the public of the
+    performances of the Work, including by public digital performance; to
+    broadcast and rebroadcast the Work by any means including signs,
+    sounds or images.
+ i. "Reproduce" means to make copies of the Work by any means including
+    without limitation by sound or visual recordings and the right of
+    fixation and reproducing fixations of the Work, including storage of a
+    protected performance or phonogram in digital form or other electronic
+    medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+limit, or restrict any uses free from copyright or rights arising from
+limitations or exceptions that are provided for in connection with the
+copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+    Collections, and to Reproduce the Work as incorporated in the
+    Collections;
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+    including any translation in any medium, takes reasonable steps to
+    clearly label, demarcate or otherwise identify that changes were made
+    to the original Work. For example, a translation could be marked "The
+    original work was translated from English to Spanish," or a
+    modification could indicate "The original work has been modified.";
+ c. to Distribute and Publicly Perform the Work including as incorporated
+    in Collections; and,
+ d. to Distribute and Publicly Perform Adaptations.
+ e. For the avoidance of doubt:

+     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme cannot be waived, the Licensor
+        reserves the exclusive right to collect such royalties for any
+        exercise by You of the rights granted under this License;
+    ii. Waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme can be waived, the Licensor waives the
+        exclusive right to collect such royalties for any exercise by You
+        of the rights granted under this License; and,
+   iii. Voluntary License Schemes. The Licensor waives the right to
+        collect royalties, whether individually or, in the event that the
+        Licensor is a member of a collecting society that administers
+        voluntary licensing schemes, via that society, from any exercise
+        by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights in
+other media and formats. Subject to Section 8(f), all rights not expressly
+granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms
+    of this License. You must include a copy of, or the Uniform Resource
+    Identifier (URI) for, this License with every copy of the Work You
+    Distribute or Publicly Perform. You may not offer or impose any terms
+    on the Work that restrict the terms of this License or the ability of
+    the recipient of the Work to exercise the rights granted to that
+    recipient under the terms of the License. You may not sublicense the
+    Work. You must keep intact all notices that refer to this License and
+    to the disclaimer of warranties with every copy of the Work You
+    Distribute or Publicly Perform. When You Distribute or Publicly
+    Perform the Work, You may not impose any effective technological
+    measures on the Work that restrict the ability of a recipient of the
+    Work from You to exercise the rights granted to that recipient under
+    the terms of the License. This Section 4(a) applies to the Work as
+    incorporated in a Collection, but this does not require the Collection
+    apart from the Work itself to be made subject to the terms of this
+    License. If You create a Collection, upon notice from any Licensor You
+    must, to the extent practicable, remove from the Collection any credit
+    as required by Section 4(b), as requested. If You create an
+    Adaptation, upon notice from any Licensor You must, to the extent
+    practicable, remove from the Adaptation any credit as required by
+    Section 4(b), as requested.
+ b. If You Distribute, or Publicly Perform the Work or any Adaptations or
+    Collections, You must, unless a request has been made pursuant to
+    Section 4(a), keep intact all copyright notices for the Work and
+    provide, reasonable to the medium or means You are utilizing: (i) the
+    name of the Original Author (or pseudonym, if applicable) if supplied,
+    and/or if the Original Author and/or Licensor designate another party
+    or parties (e.g., a sponsor institute, publishing entity, journal) for
+    attribution ("Attribution Parties") in Licensor's copyright notice,
+    terms of service or by other reasonable means, the name of such party
+    or parties; (ii) the title of the Work if supplied; (iii) to the
+    extent reasonably practicable, the URI, if any, that Licensor
+    specifies to be associated with the Work, unless such URI does not
+    refer to the copyright notice or licensing information for the Work;
+    and (iv) , consistent with Section 3(b), in the case of an Adaptation,
+    a credit identifying the use of the Work in the Adaptation (e.g.,
+    "French translation of the Work by Original Author," or "Screenplay
+    based on original Work by Original Author"). The credit required by
+    this Section 4 (b) may be implemented in any reasonable manner;
+    provided, however, that in the case of a Adaptation or Collection, at
+    a minimum such credit will appear, if a credit for all contributing
+    authors of the Adaptation or Collection appears, then as part of these
+    credits and in a manner at least as prominent as the credits for the
+    other contributing authors. For the avoidance of doubt, You may only
+    use the credit required by this Section for the purpose of attribution
+    in the manner set out above and, by exercising Your rights under this
+    License, You may not implicitly or explicitly assert or imply any
+    connection with, sponsorship or endorsement by the Original Author,
+    Licensor and/or Attribution Parties, as appropriate, of You or Your
+    use of the Work, without the separate, express prior written
+    permission of the Original Author, Licensor and/or Attribution
+    Parties.
+ c. Except as otherwise agreed in writing by the Licensor or as may be
+    otherwise permitted by applicable law, if You Reproduce, Distribute or
+    Publicly Perform the Work either by itself or as part of any
+    Adaptations or Collections, You must not distort, mutilate, modify or
+    take other derogatory action in relation to the Work which would be
+    prejudicial to the Original Author's honor or reputation. Licensor
+    agrees that in those jurisdictions (e.g. Japan), in which any exercise
+    of the right granted in Section 3(b) of this License (the right to
+    make Adaptations) would be deemed to be a distortion, mutilation,
+    modification or other derogatory action prejudicial to the Original
+    Author's honor and reputation, the Licensor will waive or not assert,
+    as appropriate, this Section, to the fullest extent permitted by the
+    applicable national law, to enable You to reasonably exercise Your
+    right under Section 3(b) of this License (right to make Adaptations)
+    but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
+OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
+ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
+ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate
+    automatically upon any breach by You of the terms of this License.
+    Individuals or entities who have received Adaptations or Collections
+    from You under this License, however, will not have their licenses
+    terminated provided such individuals or entities remain in full
+    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+    survive any termination of this License.
+ b. Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the
+    Work under different license terms or to stop distributing the Work at
+    any time; provided, however that any such election will not serve to
+    withdraw this License (or any other license that has been, or is
+    required to be, granted under the terms of this License), and this
+    License will continue in full force and effect unless terminated as
+    stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection,
+    the Licensor offers to the recipient a license to the Work on the same
+    terms and conditions as the license granted to You under this License.
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+    offers to the recipient a license to the original Work on the same
+    terms and conditions as the license granted to You under this License.
+ c. If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this License, and without further action
+    by the parties to this agreement, such provision shall be reformed to
+    the minimum extent necessary to make such provision valid and
+    enforceable.
+ d. No term or provision of this License shall be deemed waived and no
+    breach consented to unless such waiver or consent shall be in writing
+    and signed by the party to be charged with such waiver or consent.
+ e. This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings,
+    agreements or representations with respect to the Work not specified
+    here. Licensor shall not be bound by any additional provisions that
+    may appear in any communication from You. This License may not be
+    modified without the mutual written agreement of the Licensor and You.
+ f. The rights granted under, and the subject matter referenced, in this
+    License were drafted utilizing the terminology of the Berne Convention
+    for the Protection of Literary and Artistic Works (as amended on
+    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
+    and the Universal Copyright Convention (as revised on July 24, 1971).
+    These rights and subject matter take effect in the relevant
+    jurisdiction in which the License terms are sought to be enforced
+    according to the corresponding provisions of the implementation of
+    those treaty provisions in the applicable national law. If the
+    standard suite of rights granted under applicable copyright law
+    includes additional rights not granted under this License, such
+    additional rights are deemed to be included in the License; this
+    License is not intended to restrict the license of any rights under
+    applicable law.

+   Object form, made available under the License, as indicated by a
+   copyright notice that is included in or attached to the work
+   (an example is provided in the Appendix below).
+
+   "Derivative Works" shall mean any work, whether in Source or Object
+   form, that is based on (or derived from) the Work and for which the
+   editorial revisions, annotations, elaborations, or other modifications
+   represent, as a whole, an original work of authorship. For the purposes
+   of this License, Derivative Works shall not include works that remain
+   separable from, or merely link (or bind by name) to the interfaces of,
+   the Work and Derivative Works thereof.
+
+   "Contribution" shall mean any work of authorship, including
+   the original version of the Work and any modifications or additions

+   to the Licensor or its representatives, including but not limited to
+   communication on electronic mailing lists, source code control systems,
+   and issue tracking systems that are managed by, or on behalf of, the

+
+   "Contributor" shall mean Licensor and any individual or Legal Entity
+   on behalf of whom a Contribution has been received by Licensor and
+   subsequently incorporated within the Work.
+
+2. Grant of Copyright License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,
+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+//! Windows: finding 3D mice without asking any other device anything (#2614).
+//!
+//! hidapi's enumeration opens every HID interface and reads its serial number, manufacturer and
+//! product strings: on USB, three control requests to every keyboard, mouse and touchscreen. The
+//! reader repeated it every two seconds while no 3D mouse was plugged in, and on some machines the
+//! keyboard then kept dropping off the bus and the cursor jumped. Plug and Play already names each
+//! interface's top-level usage in its hardware IDs (`HID_DEVICE_UP:0001_U:0008`: Generic Desktop,
+//! Multi-Axis Controller), so the reader asks it, which sends nothing to any device, and opens only
+//! the interfaces that are 3D mice.
+//!
+//! The configuration manager has no safe API, hence the `unsafe_code` allowance on this module
+//! (the app crate denies it; see `native_crash.rs`).
