-about: Help reproduce and fix a SolidCraft problem
-title: ''
-labels: ''

----
-
-## Behavior
-
-What did you expect, and what happened instead?
-
-## Reproduction
-
-Include steps, SolidCraft version/commit and relevant environment details. Prefer a small example without private design data.
-
-When the problem shows on a particular design, `solidcraft-cli script design.solidcraft --out repro.json` turns its history into a script that `solidcraft-cli eval repro.json` replays; attach it, trimmed to the failing step if you can.
-
-## Screenshots of the behavior (when observable)
-
-For observable CAD, UI or model behavior, include actual descriptive screenshots or a short recording from a small reproduction. This includes kernel, geometry, assembly and backend effects that can be shown in the app. Coding agents should run the app and capture the evidence themselves, rather than asking a human for evidence they can produce. Show the actual failure/result, preferably before and after, with brief steps, expected/actual behavior and annotations where helpful.
-
-Flowcharts and Mermaid diagrams cannot substitute for evidence of visible behavior. Use diagrams for architectural reasoning when actual screenshots cannot illustrate the point. Changes with no useful observable behavior may omit screenshot/video evidence. Exclude private designs and sensitive details; attach media or link to an accessible recording rather than committing generated review artifacts.

-SolidCraft is open-source parametric 3D CAD in Rust: sketch, constrain, extrude, and change a
-parameter to watch the timeline rebuild. [Documentation](https://bherbruck.github.io/solidcraft/)
-· [try it in the browser](https://bherbruck.github.io/solidcraft/app/) ·
-[contributing](https://github.com/bherbruck/solidcraft/blob/main/CONTRIBUTING.md) ·
-[issues](https://github.com/bherbruck/solidcraft/issues). AI agents can model with it over MCP:
-`solidcraft-cli mcp` ([how](https://bherbruck.github.io/solidcraft/guide/mcp.html)).
-
-**What's new** in SolidCraft {version} is listed below, and the
-[ROADMAP](https://github.com/bherbruck/solidcraft/blob/main/ROADMAP.md#known-limitations) lists
-the known limitations. Designs from every earlier version open in this one.
-
-**Upgrading from 0.7 or earlier.** 0.8 changed the Linux app ID to `ai.storyteller.solidcraft`:
-`flatpak update` offers to replace the old app, and the `.deb`, `.rpm` and AppImage remove the old
-menu entry.
-
-**Upgrading from 0.5 or earlier.** 0.6 renamed SolveCraft to SolidCraft and made the zip
-container the default save format. `.solvecraft` designs, old settings folders and
-`SOLVECRAFT_*` variables are still picked up, and `solvecraft-cli` still forwards to
-`solidcraft-cli`. Want plain JSON? Use **File ▸ Save As JSON…** or `--save design.json`. On
-macOS, replace `SolveCraft.app` with `SolidCraft.app`. Details:
-[compatibility notes](https://github.com/bherbruck/solidcraft/blob/main/docs/compatibility.md).
-
-Documentation, the browser app and the Flatpak feed use the SolidCraft project Pages URLs.
-
-**Which file?**
-- **Windows:** `SolidCraft-{version}-windows-x64.exe` runs as is. Or install the `.msi`, or unzip the
-  `-portable.zip` (x64, x86 and arm64).
-- **macOS 11+** (Apple silicon and Intel): open the `.dmg` and drag `SolidCraft.app` onto Applications.
-  The CLI is in `solidcraft-cli-{version}-macos-universal.zip`.
-- **Linux** (x86_64 and aarch64, glibc 2.35+): the `.AppImage` (`chmod +x`, then run it), the
-  `.deb` or `.rpm`, the `.flatpak` (`flatpak install --user <file>`), the `.snap`
-  (`sudo snap install --dangerous <file>`, or `sudo snap install solidcraft` from the Snap Store), or the `.tar.gz`.
-- **FreeBSD:** `tar -xzf solidcraft-{version}-freebsd-x86_64.tar.gz --strip-components 1 -C /usr/local`.
-- **Web:** `solidcraft-web-{version}.zip` is a static site to host yourself.
-- `SHA256SUMS.txt`: `sha256sum -c SHA256SUMS.txt --ignore-missing`.
-- Files without a version in the name (`solidcraft-windows-x64.msi`, `solidcraft-linux-x86_64.AppImage`, …)
-  are the same packages under fixed names, for download links that always fetch the latest release.
-
-For Flatpak feed installation and updates, add Flathub for the required runtime before
-installing SolidCraft; keep both remotes in the same user installation:
-
-```sh
-flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
-flatpak remote-add --user --if-not-exists solidcraft https://bherbruck.github.io/solidcraft/flatpak/solidcraft.flatpakrepo
-flatpak install --user solidcraft ai.storyteller.solidcraft
-flatpak run ai.storyteller.solidcraft
-```
-
-Flatpak installs from 0.7 or earlier use the old ID `ai.storyteller.solvecraft`: `flatpak update --user`
-offers to replace it with `ai.storyteller.solidcraft`, and settings move along.
-
-Single-file `.flatpak` bundles include the runtime repository address; missing runtimes
-still need an internet connection. [Linux installation details](https://bherbruck.github.io/solidcraft/guide/getting-started.html#linux-flatpak).
-
-The builds aren't signed yet. On macOS, right-click `SolidCraft.app` in Applications and choose
-**Open** the first time (or run `xattr -dr com.apple.quarantine /Applications/SolidCraft.app`).
-On Windows, SmartScreen may say "Windows protected your PC": **More info**, then **Run anyway**.
-Licences are built in (Help ▸ About ▸ Licences, `solidcraft-cli licences`); the packages also
-install `THIRD-PARTY-LICENSES.txt`.

-# 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.
-
-## 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 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.
-
-`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 three exceptions, in the app crate
-  (which denies it instead), have no safe API: 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.
-- 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.** Every UI icon is drawn in collected code
-  (`assets/icons/ui/source/`, compiled through `crates/ui-egui/src/icons.rs`). 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).
-- **Rust only.** Units are millimetres and radians internally; Z is up. The one 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**: `origin` is github.com/bherbruck/solidcraft. Changes land through **pull requests**:
-  push a branch, open a PR, and let GitHub CI run. Maintainers (and agents working for them) may
-  merge their own PR as soon as CI is green (`gh pr merge --squash`); a trivial fix (docs, typos)
-  may be merged right away. Keep each PR to one topic, rebase or merge `main` into it when it
-  conflicts, 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 current upstream commits and the relevant
-  PR's merge status. Keep your branch current with upstream merges, resolve conflicts without
-  discarding others' work, and re-run validation when integration changes the result. Use
-  `git pull --rebase origin main` before pushing as above; never force-push. Report the checked
-  upstream/PR state, any conflicts resolved and the validation performed. 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.
-
-## Claim = a draft PR
-- Before working on issue #N, check nobody has it: `gh pr list -R bherbruck/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. Don't claim by commenting or by editing files.
-- 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).
-- 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.

-## Incremental HDR codec adapter

-MIT OR Apache-2.0. Metadata parsing still uses that library. The adapter makes row
-work cooperative and adds checked run lengths, zero-run rejection, width validation,
-header/input/radiance bounds and cancellation. Original licence texts are retained
-in THIRD-PARTY-LICENSES.txt; no images or artwork from that project are copied.

-| inflections 1.1.1 (build-time, through gltf-derive) | case conversion in gltf's derive macros | MIT |
-| lazy_static 1.5.1 (through gltf-json) | | MIT OR Apache-2.0 |
-
-The glTF test files are built by the tests themselves (crates/io/src/gltf_in_tests.rs,
-crates/engine/src/tests/gltf_import.rs); no third-party models are committed.
-
-## FreeCAD and Rhino import library
-
-FreeCAD `.FCStd` and Rhino `.3dm` files are read with [cadmpeg](https://github.com/cadmpeg/cadmpeg)
-0.6.1 (Apache-2.0), linked as the crates `cadmpeg-core`, `cadmpeg-ir`, `cadmpeg-registry`,
-`cadmpeg-container`, `cadmpeg-codec-freecad`, `cadmpeg-codec-rhino` and `cadmpeg-codec-step`
-in native builds (`crates/io/src/native_cad.rs`). Only those open-format codecs are built: no
-default features, so cadmpeg's codecs for commercial CAD formats and its ShapeManager/ACIS
-codec are not compiled in. Its licence text is in THIRD-PARTY-LICENSES.txt; no code from it is
-copied into SolidCraft.

-## Vendored renderer compatibility fix
-
-`vendor/egui-wgpu` is egui-wgpu 0.36.2 from https://github.com/emilk/egui
-(MIT OR Apache-2.0; both original licence texts are included). Rust sources and
-its original `egui.wgsl` shader are retained; no images or other artwork are copied.
-SolidCraft's narrow patch selects a safe 1x MSAA path on the chosen OpenGL adapter
-and shares that effective count with the surface attachments and CAD callbacks.
-Vulkan, DirectX 12, Metal and WebGPU retain their requested multisampling.
-A frame whose meshes the GPU refuses to stage (device lost or out of memory) is
-skipped with a warning instead of panicking (#1469).

-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.
-
-## 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 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.
-
-`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 three exceptions, in the app crate
-  (which denies it instead), have no safe API: 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.
-- 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.** Every icon is drawn in code
-  (`crates/ui-egui/src/icons.rs`). 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`.
-- **Rust only.** Units are millimetres and radians internally; Z is up. The one 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**: `origin` is github.com/bherbruck/solidcraft. Changes land through **pull requests**:
-  push a branch, open a PR, and let GitHub CI run. Maintainers (and agents working for them) may
-  merge their own PR as soon as CI is green (`gh pr merge --squash`); a trivial fix (docs, typos)
-  may be merged right away. Keep each PR to one topic, rebase or merge `main` into it when it
-  conflicts, 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`).
-
-## Claim = a draft PR
-- Before working on issue #N, check nobody has it: `gh pr list -R bherbruck/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. Don't claim by commenting or by editing files.
-- 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).
-- 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.

-# Contributing to SolidCraft
-
-SolidCraft is an open-source parametric 3D CAD app written in pure Rust.
-You sketch on a plane, constrain the sketch, turn profiles into solids, and
-change a parameter to watch the timeline rebuild. It runs as a desktop app (Windows, Linux), in
-the browser (wasm + WebGPU/WebGL2), headless from a CLI, and as an MCP server that AI agents can
-model with.
-
-Help is welcome, whether that's a one-line fix or owning a whole area. This page covers how to
-build it, how the code is laid out, the few rules that aren't negotiable, and where help is
-needed most.
-
-## Get it running (about 10 minutes on a fast machine)
-
-You need stable Rust 1.95 or newer (required by egui/eframe 0.36). For the web
-build you also need `rustup target add wasm32-unknown-unknown` and [`trunk`](https://trunkrs.dev).
-
-```sh
-git clone https://github.com/bherbruck/solidcraft && cd solidcraft
-cargo run --release -p solidcraft -- --sample      # desktop app with a sample part
-cargo xtask test                                   # unit, engine and UI-scenario tests
-cargo xtask ci                                     # everything a PR must pass (see below)
-```
-
-SolidCraft is the product, repository, Cargo package and executable name.
-Build the desktop app with `cargo build --release -p solidcraft`, or the CLI with
-`cargo build --release -p solidcraft-cli`. Run the CLI with
-`cargo run --release -p solidcraft-cli -- commands` (or `target/release/solidcraft-cli commands`
-after building). The old name appears only in the compatibility shims listed in
-[docs/compatibility.md](docs/compatibility.md); don't add new uses of it.
-
-Web: `cd apps/solidcraft-web && trunk serve --release`, then open the printed URL (`?sample`
-opens the sample part, `?webgl` forces WebGL2). Saving and opening files in the browser needs
-HTTPS or localhost, because it uses the Origin Private File System.
-
-Windows from Linux: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
-
-### NixOS: `nix develop`
-
-NixOS has no `/usr/lib`, so nothing is on `LD_LIBRARY_PATH` and a plain `cargo run` finds none of
-the libraries the app loads at run time: the Wayland ones winit opens the window through, the EGL
-loader wgpu renders through, and libdbus-1, which rfd's file dialogs reach xdg-desktop-portal
-through (a dialog then never appears and the pick returns no path):
-
-```
-ERROR solidcraft: winit EventLoopError: ... The wayland library could not be loaded
-ERROR eframe::native::run: Exiting because of error: WGPU error: Failed to create surface for any enabled backend: {}
-ERROR rfd::backend::xdg_desktop_portal::portal::libdbus: Can't connect to a portal: libdbus-1.so not found
-```
-
-`nix develop` (the [`flake.nix`](flake.nix) in the repository root) supplies Wayland,
-X11, EGL, Vulkan-loader and D-Bus runtime libraries. It also exposes the NixOS
-driver manifests in `/run/opengl-driver/share`, so Vulkan can discover the system
-drivers. Enable `hardware.graphics.enable` on NixOS; other Linux distributions
-may need a matching [nixGL wrapper](https://github.com/nix-community/nixGL).
-The default development shell retains the Rust/C toolchain already on `PATH`;
-`nix develop .#rust` supplies the pinned toolchain and builds in `target/nix`.
-
-To launch, use `nix run .#solidcraft -- --sample`. To install the app's terminal
-commands, desktop entry and generated icons, use `nix profile install .#solidcraft`.
-`nix build` alone creates a build result; it does not install a launcher in your
-desktop menu. The installed `solidcraft` command runs the wrapped app; `solidcraft-cli` is included as
-well. See
-[Nix installation and troubleshooting](docs/nix.md) for remote-flake commands,
-desktop integration and how to distinguish an old executable on `PATH`.
-
-## How the code is laid out
-
-The [README](README.md#architecture) has the layer table. The short version:
-
-- `crates/geom`: vectors, planes, meshes, measures.
-- `crates/sketch`: our own constraint solver, plus profile finding.
-- `crates/kernel`: the B-rep kernel boundary. It wraps [truck](https://github.com/ricosjp/truck),
-  and it's the only crate allowed to touch truck. Fillets, chamfers, shell/offset, Delete Face,
-  Split Face, STEP/IGES read and write, and face provenance are our own code here. Patched
-  copies of three truck crates live in `vendor/` and are excluded from our fmt/clippy rules.
-- `crates/doc`: the document. It holds parameters and expressions, the feature timeline and its
-  incremental rebuild, components and occurrences, joints, appearances, and persistent naming.
-- `crates/io`: design files and mesh formats (3MF, STL, OBJ).
-- `crates/engine`: the session and the command registry. **Everything the user can do is a
-  command**, and the toolbar, dialogs, scripts, CLI, control channel and MCP all run the same
-  commands.
-- `crates/ui-egui`: the desktop/web front end (egui + wgpu). It's swappable; nothing below it
-  depends on egui.
-- `crates/mcp`, `apps/solidcraft`, `apps/solidcraft-cli`, `apps/solidcraft-web`.
-
-`cargo xtask layers` fails the build if a lower layer depends on a higher one.
-
-## Rules that aren't negotiable
-
-1. **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. We don't drive, script, automate or extract data from commercial CAD
-   products, and we never copy another product's code, icons, artwork, help text, tooltips,
-   templates or materials. Command ids are our own (`solid.fillet`).
-2. **No GPL/LGPL/AGPL code, not even reading it.** That rules out OpenCASCADE, FreeCAD
-   (including planegcs), SolveSpace, CadQuery/OCP, LibreCAD and QCAD. SolidCraft is
-   MIT OR Apache-2.0, and its solver and blends are written from the maths. (Running an
-   open-source application to get reference values for a test is fine; reading its source is
-   not.) Permissive
-   dependencies are fine. Note which one you're adding and why in the PR. THIRD-PARTY-LICENSES.txt
-   lists it once the change lands: the Generated files workflow rewrites it on `main`.
-   Nightly/manual CI also scans advisories, bans and sources with cargo-deny; see
-   [the local command and coverage limits](docs/book/src/dev/testing.md#dependency-advisories).
-3. **Every asset is original or openly licensed and has a row in
-   [ATTRIBUTION.md](ATTRIBUTION.md).** Icons are drawn in code (`crates/ui-egui/src/icons.rs`).
-   `cargo xtask assets` enforces this.
-4. **Never crash.** People trust a CAD app with their work.
-   - Non-test code never uses `unwrap`, `expect`, `panic!` or indexing on input-derived data.
-     There's no `unsafe` outside `apps/solidcraft/src/open_documents.rs` (macOS file-open events)
-     and `apps/solidcraft/src/native_crash.rs` (Windows native crash capture), and the compiler
-     denies it.
-   - An unsupported case returns an error ("not supported yet: …"); it never panics.
-   - Every call into truck goes through `solidcraft_kernel::guard`.
-   - Every crash fix comes with a regression test.
-5. **Everything is a command, with a test.** A new feature means a `CommandSpec` in
-   `crates/engine/src/cmd/`, engine tests that measure the result (volume, area,
-   face/edge/vertex counts against a value you can derive), and for UI work a scenario (below).
-6. **One set of camera controls.** Every page or canvas that shows a view (the modelling
-   viewport, the Render preview, and any new page such as a flat pattern or drawing) calls
-   `navigation::handle` (`crates/ui-egui/src/navigation.rs`) for its camera input, with
-   `NavCaps` saying whether it can orbit (off for flat 2D pages) and pick. New canvases must use
-   `navigation::handle`; never read drags, the wheel or pinch to move the camera yourself. The
-   `hand_rolled_camera_input_is_rejected` test fails if a page does.
-
-[AGENTS.md](AGENTS.md) has the long form of these rules. It's written for AI agents, but it's
-the most complete description of the house style.
-
-## Tests
-
-| What | Where | Run |
-|---|---|---|
-| Unit and engine tests | next to the code, or `*_tests.rs` files | `cargo xtask test` (or `cargo test --workspace --profile ci`) |
-| UI scenarios | `crates/ui-egui/tests/scenarios/*.json` | part of `cargo test` |
-| Reference tests | `cargo xtask oracle` | `tests/oracle/` (see below) |
-
-**UI scenarios** drive the real app headless: start a tool, click a plane or a sketch point,
-press keys, then assert on the result.
-
-```json
-[
-  {"start": "sketch.create"},
-  {"click": {"plane": "XY"}},
-  {"start": "sketch.rectangle.two_point"},
-  {"click": {"sketch": [0, 0]}},
-  {"click": {"sketch": [40, 30]}},
-  {"expect": {"errors": 0}}
-]
-```
-
-A new `.json` file in that folder is picked up automatically. To record a bug before it's fixed,
-put `{"pending": "why"}` in the scenario, and remove it in the PR that fixes the bug.
-
-**A failing test without its fix can't merge as-is:** it would turn `main`'s CI red for everyone.
-Either include the fix in the same PR, or mark the test `#[ignore = "fails until #123 is fixed"]`
-(it can then merge right away), and remove that line in the PR that fixes the bug.
-
-**Use the `ci` profile.** CI runs the tests with `--profile ci`: light optimisation, line tables,
-no LTO, and debug assertions off (truck has debug-only assertions that reject valid geometry). It
-builds several times faster than `--release`. If a test fails only in a plain debug build, say so
-in the PR. `cargo xtask test` builds the tests with it and then runs every test binary at once
-(`cargo test` runs them one after another); arguments after `--` go to each binary, e.g.
-`cargo xtask test -- shell`. Tests run beside each other on a busy machine, so a test must not
-depend on wall-clock timing.
-
-**PRs test what they touch; main and nightly test everything.** On a pull request, CI maps the
-changed files to workspace packages and runs Clippy, the test build and the tests for those and
-the packages that depend on them (`scripts/ci/affected.py`, self-tested in the `checks` job). A
-change to `Cargo.lock`, the root `Cargo.toml`, `.cargo/`, `.config/`, `.github/`, `vendor/`,
-`tests/`, `scripts/` or any file outside a package runs the whole workspace, as does every push
-to `main`, the nightly run and Run workflow.
-
-**CI shards the tests.** One job builds them into a cargo-nextest archive and four jobs run a
-quarter each, so every test runs in its own process: don't rely on state left by another test.
-Pull requests skip a few heavy tests (one to four minutes each), which run on every push to
-`main` and nightly; check the `main` run after merging. They are listed in
-`.config/nextest.toml` and the [testing page](docs/book/src/dev/testing.md):
-
-- `solidcraft-engine`: `tests::hostile_params_never_panic`, everything in `tests::robustness` and
-  `tests::robustness_goldens` (pull requests that touch `crates/kernel` run its `sample_*` part),
-  `pattern_suppress_tests::enclosure_arc_extinction_keeps_a_real_sharp_inner_lip_after_resize_and_reopen`,
-  `pattern_suppress_tests::enclosure_datums_follow_wall_height_and_board_depth_with_material_proofs`,
-  `cmd::plastic::tests::enclosure_snap_fit_follows_resized_front_wall`, the `atomic_commands` contract tests
-- `solidcraft-kernel`: `tests::boolean_identity_on_tangent_primitives`, and the `boolean_props` property tests
-  (these run only in the nightly "Property tests" job: their inputs are random, so main skips them too)
-- `solidcraft-ui-egui` scenarios: `acceptance_sensor_enclosure`
-
-**The action matrix** tries every ordinary action on every face, edge, vertex and body of a
-corpus of designs against a checked-in ratchet ([docs/action-matrix.md](docs/action-matrix.md)).
-A pull request that makes an action pass should record it with `cargo xtask action-matrix --bless`;
-one that makes a passing action fail fails the sample every CI run checks.
-
-**The reference tests** are 76 parts in [`tests/oracle/`](tests/oracle/), each a `recipe.json`
-in our own format with an `expected.json` beside it. SolidCraft rebuilds the recipe and compares
-body count, volume, area, centre of mass and bounding box (and, where there is a `reference.stl`,
-the surface itself). Expected values are either worked out in closed form
-(`tools/oracle-analytic/`) or computed by building the same recipe in FreeCAD, run as a separate
-program (`tools/freecad-oracle/`); each file says which. [docs/oracle.md](docs/oracle.md) has
-the current results, and CI runs `cargo xtask oracle` on every pull request. A case that fails
-because of a known bug names its issue in `expected.json` (`"known_failure": "#123"`); never
-change an expected value to match SolidCraft's output.
-
-## Changing the design file format
-
-A design file says which format it is in (`"format": "solidcraft/N"`). If your change saves
-something new in a design (a field, a feature type, a new kind of name), or makes older designs
-mean something else, it needs a format change. **Add one file, and edit nothing shared:**
-
-1. Create `crates/doc/src/format/pending/<what-it-is>.rs` (lowercase, dashes). Start it with a
-   `//!` note: what is saved, what older designs get without it, and that the last release asks
-   for an update instead of meeting it.
-2. If older designs must be rewritten as they open, put `pub fn step(v: &mut Value) ->
-   crate::Result<()>` in the same file. Pending steps run in file-name order, after the older
-   formats' steps.
-3. Don't touch `FORMAT`, `JSON_STEPS`, the history in `crates/doc/src/format.rs`, another
-   change's file, or any `v<N>/` folder: those are fixed once released.
-
-That's all. The build counts the files: while any are pending it writes the next format number,
-which no release reads, so a release refuses a design that has your change instead of losing it.
-A file also lists the pending changes it has (`format_pending`), so a later development build
-runs only the steps that file is missing. Two pull requests that each add a change merge without
-a conflict. `crates/doc/src/format/pending/README.md` has an example.
-
-**At release time** the maintainer runs `scripts/fold-format-pending.sh`, which moves the pending
-files into `crates/doc/src/format/v<N>/` and fixes that number for good (see
-[docs/releasing.md](docs/releasing.md)). Never add a file to a `v<N>/` folder afterwards.
-
-## Lists many changes add to
-
-Some files gain an item in many pull requests at once. They are kept so that two changes that
-each add an item only meet when their items are neighbours, which spares everyone a conflict
-and a fresh CI run:
-
-- **Message catalogs** (`assets/locales/*.json`): one message per line, sorted by id. Add your
-  message anywhere and run `cargo xtask lists --fix`; `cargo xtask lists` (in `cargo xtask ci`
-  and the Lists workflow) fails on an unsorted catalog or an id that appears twice.
-- **`mod` lines**: one per line, in the sorted group they belong to (`cargo fmt` keeps each group
-  sorted). Add a new module into the existing group, not as a new group at the end.
-- **Languages** (`crates/ui-egui/src/i18n.rs`): one per line, English first, then by id (a test
-  checks it).
-- **Generated files**: `THIRD-PARTY-LICENSES.txt` and `docs/features.md` are rewritten on `main`
-  after each merge by the Generated files workflow (`cargo xtask licences`, `cargo xtask
-  features`). Don't regenerate or edit them in a pull request.
-- **Design format**: one file per change, never an edit to a shared number (above).
-

-1. Work is tracked in [GitHub issues](https://github.com/bherbruck/solidcraft/issues), labelled
-   by area (`area:kernel`, `area:sketch`, `area:doc`, `area:ui`, `area:infra`). For anything
-   bigger than a bug fix that has no issue yet, open one first. **Claim the issue with a draft
-   PR** before you start, so two people don't build the same thing:
-   - Check nobody has it: `gh pr list -R bherbruck/solidcraft --state open --search "#N"`.
-   - Branch from the latest `main`, commit `git commit --allow-empty -m "claim: #N"`, push, and
-     open a **draft** PR titled `<summary> (#N)`, e.g. `Fillet: variable radius along a chain (#123)`.
-   - **The lowest-numbered open PR for an issue wins.** If yours lost, close it (or offer to help
-     on the other one).
-   - 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.
-   - Mark the PR ready for review when it is done.
-2. Branch from `main` and keep the PR to one topic.
-3. Run `cargo xtask ci` before pushing. It runs fmt, the asset, licence and layer checks,
-   clippy (`-D warnings`), then the tests with the wasm build check alongside. A PR has to pass it.
-4. Reference the issue (`Fixes #12`). In the PR, say what you tested and how. For geometry work, include the measured numbers (and
-   the expected ones).
-
-Comment `/claim` on an issue to take it: you are assigned, it gets the `in progress` label, and
-the bot replies with the deadline. Open a draft PR referencing the issue within 72 hours, or the
-claim lapses and the issue is freed again; a claim with a PR is freed after 14 days without
-pushes. `/unclaim` releases it early (only you or a maintainer can). Issues a maintainer has
-taken are never freed automatically.
-
-Help reviewers see what the words mean. For observable CAD, UI or model behavior, please
-include actual descriptive screenshots or a short recording in the issue or PR. This evidence
-is required for changes or bugs that can be demonstrated in the app, including kernel,
-geometry, assembly and backend work. Coding agents should run a small reproduction and
-capture the evidence themselves; please don't ask a human for evidence the agent can produce.
-Show the actual failure or result, preferably before and after, with brief steps and
-expected/actual behavior. An arrow or annotation can help identify the detail that matters.
-
-Flowcharts and Mermaid diagrams cannot replace evidence of visible behavior. Diagrams are
-useful 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 example without private designs or sensitive details; attach the media or link to an
-accessible recording rather than committing generated review artifacts.
-
-Keep checking upstream commits and the relevant PR's merge status throughout the work and
-before handoff. Integrate upstream merges, resolve conflicts without losing others' changes,
-and validate the integrated result. Before pushing, run `git pull --rebase origin main`, re-run
-CI if it brought changes, and push without force. Report the upstream/PR state you checked,
-any conflicts resolved and validation results. While a task remains active, follow an open
-PR through its status changes; at handoff, clearly identify anything still awaiting merge.
-
-Much of SolidCraft so far was written by AI coding agents (Claude) working in parallel, each
-owning one area, with a human setting direction and reporting bugs. Their working notes are in
-[AGENTS.md](AGENTS.md). Human contributors are just as welcome. Use whatever tools you like, as
-long as the change meets the rules above.
-
-## Where help is wanted most
-
-**Kernel speed (slow fillets, booleans, STEP):** please don't rewrite the current kernel code for speed; it is being replaced by [solidcore](https://github.com/bherbruck/solidcore) ([progress](https://bherbruck.github.io/solidcore/)). Report slow cases with a file under the `kernel-perf` label, and put kernel effort into solidcore instead. See [#1597](https://github.com/bherbruck/solidcraft/issues/1597).
-
-See the [`help wanted`](https://github.com/bherbruck/solidcraft/labels/help%20wanted) and
-[`good first issue`](https://github.com/bherbruck/solidcraft/labels/good%20first%20issue) labels.
-In order of how much they'd help users:
-
-1. **Fillet and blend robustness.** Fillets are our own code (truck has no fillet operation).
-   Constant, variable-radius and chord fillets work, and so do corners where fillets of
-   different radii meet, including three rounds meeting at a vertex. Next are setback corners, fillets along curved edges between curved
-   faces, and fillets that consume neighbouring faces.
-2. **Boolean robustness.** A random-design fuzzer currently gets about half of its designs
-   through without a kernel error. Each failing seed is a reproducible bug.
-3. **Y-up / Z-up.** SolidCraft is Z-up only, so most STEP files (from SolidWorks, Onshape, or
-   Fusion's default) open lying on their backs. Fusion solves this with a "default modeling
-   orientation" preference.
-4. **Imported appearances.** Colours from STEP files are lost when a feature changes the
-   imported body. They should become design appearances on import.
-5. **Drawings, CAM and mesh tools.** These are out of scope for now (see
-   [ROADMAP.md](ROADMAP.md)), but anyone who wants to own one is welcome.

-## What works
-
-- **Current-view DXF export** from File → Export Current View as DXF, with hidden edges
-  omitted or dashed, shown body placements and the current camera. See [view DXF](docs/view-dxf.md).
-
-- **Sketches** on origin planes, offset planes or planar faces: lines, rectangles, circles,
-  arcs, polygons, slots, ellipses, fit/control splines, conics and text; construction geometry,
-  projection, trimming, fillets and chamfers, including corners at the origin.
-  New face attachments retain supported construction identities and chosen occurrences;
-  missing sources expose an explicit plane repair workflow. See [face attachments](docs/face-attachments.md).
-  Explicitly closed fit splines and closed associative offsets use periodic C2 interpolation.
-  Supported convex line-and-arc offsets retain their identity when an inset consumes corner
-  arcs, and linked extrusions follow the current boundary. Breaking the association freezes
-  the boundary and keeps existing extrusions usable.
-  Curve drawing and picking adapt together to zoom and display scale, including small circles
-  at Fit and sketches in placed components.
-- **Constraints and dimensions** solved by our own solver. Points the constraints fix relative
-  to known geometry are placed exactly by construction (loci intersections and rigid-cluster
-  decomposition, after Owen 1991 and Fudos–Hoffmann 1997); Levenberg–Marquardt solves the rest,
-  and the rank of its Jacobian gives the remaining degrees of freedom. Constraints: coincident,
-  point on curve, horizontal/vertical, parallel, perpendicular, tangent, curvature (G2), equal,
-  concentric, collinear, midpoint, symmetry, fix; linear, aligned, horizontal, vertical,
-  point-to-line, radius, diameter, angle, arc sweep, arc length and slot length dimensions driven
-  by parameters. Over-constraining edits are rejected; fully constrained geometry turns black.
-  Dragging solves the sketch every frame and rebuilds the model once, when the drag ends.
-  Select a line or its two endpoints, type its dimension and press Enter to commit one undo
-  step; with Sketch Dimension it's D, click, type, Enter. Fit keeps sketch geometry clear of the palette and navigation controls.
-- **Profiles** found automatically, including regions split by lines and holes inside outlines.
-  Newly captured complete adaptive boundaries retain their outer and hole source identities
-  when spline span counts change. Partial or ambiguous boundaries do not qualify.
-- **Features** on a parametric timeline: extrude, revolve, sweep, loft, fillet/chamfer,
-  shell, draft, holes, threads, patterns, mirror, split, combine, move and construction geometry.
-  The timeline rebuilds incrementally; features can be edited, suppressed, renamed, reordered
-  and deleted. Supported geometry and current limitations are described in [ROADMAP.md](ROADMAP.md).
-  New revolves preserve symmetric and two-sided angular placement across reversed axes;
-  older designs retain their saved convention when reopened or edited.
-- **Parameters and configurations** with unit-aware expressions (`2 * width + 5 mm`,
-  `angle / 2`), ordered rules, feature suppression and per-row body materials/appearances.
-- **Assemblies** with nested components and occurrences, joints, motion studies, contact sets,
-  interference and material-aware mass properties. Recorded body transfers preserve modelling
-  history and world placement; 3D sketch wires retain their coordinate frames through edits.
-- **Sheet metal** with flanges, hems, fold/unfold/refold, material cutouts, flat patterns,
-  retained shallow prismatic pockets, exact line/arc/circle DXF outlines and bend tables;
-  plastic enclosure features and rules. Pocket depth and side survive unfold/refold and appear
-  separately from through-hole outlines in the flat preview and DXF.
-- **Files**: design containers (`.solidcraft`) with lossless binary mesh payloads;
-  plain JSON remains supported for opening, Save As and export. Desktop Open can show a saved
-  provisional picture from warm geometry caches while rebuilding before editing; caches never
-  replace the parametric design. Export to STEP (AP242 with body names, colours and
-  components as assemblies; revolved faces as native planes, cylinders, cones, spheres and tori),
-  IGES 5.3 (manifold solid B-reps with names and colours), 3MF, STL (binary/ASCII) and OBJ, and
-  assemblies with joints as URDF for robot simulators (docs/urdf.md);
-  3MF, STL, OBJ and glTF 2.0 (`.glb`/`.gltf`, its node tree as components and its materials as
-  appearances) import as mesh bodies (they render, measure, move and export; solid features
-  need B-rep bodies). The `mesh.convert` command reconstructs supported closed constant-section parts
-  as parametric solids with planar and circular cylindrical faces;
-  STEP import (AP203/AP214/AP242 solids, assemblies, units, names, colours) and IGES import
-  (manifold solid B-reps, or trimmed and bounded surfaces sewn into solids) as a base feature
-  that later features build on — open a `.step`/`.stp`/`.igs`/`.iges` file, insert one into a
-  design, or drop it on the window ([docs/step-import.md](docs/step-import.md)); FreeCAD
-  `.FCStd` and Rhino `.3dm` solids import the same way through
-  [cadmpeg](https://github.com/cadmpeg/cadmpeg) in the desktop app and CLI.
-- **Render:** opaque surfaces can use metal fraction, roughness and dielectric IOR in the
-  integrated product viewport and CPU preview PNGs. Existing simple colors remain supported.
-  Fixed direct lighting is a preview; HDRI, refraction and texture maps are not implemented.
-  See [opaque surfaces](docs/render-opaque-pbr.md).
-- **Display meshes** from our own tessellation planner: each face becomes a plan of (u, v)
-  points and triangles that shares its edge nodes with its neighbours, so the mesh is watertight.
-  Facets follow the chord tolerance, the facet angle and a longest side, with cells at most 2:1
-  along straight directions. Box-bounded and four-cornered faces mesh as structured grids.
-  Trimmed faces are cut into four-sided patches: squares around holes, butterflies in round
-  faces, motorcycle traces from concave corners (after Lyon et al. 2019). Each patch then meshes
-  as a Coons grid. Intersection edges are evaluated by Newton on both surfaces. A compute shader
-  evaluates the plans for the whole scene in one dispatch, with a CPU fallback when the GPU
-  can't build it. Planning and evaluating the 78 reference bodies takes about 65 ms, 50–65×
-  faster than the previous mesher.
-- **Desktop app** (egui + wgpu): toolbar with workspace tabs, browser, timeline, 3D viewport with
-  axis view and navigation bar, sketch tools, feature dialogs, command palette, and a JSON-lines
-  control channel so agents and tests can drive it.
-  Feature errors and Help can open an editable **Create Issue** draft with relevant context
-  and an optional reviewed screenshot; opening GitHub does not submit the report.
-- **Headless CLI** `solidcraft-cli`: run command scripts, measure (volume, area, centre of mass,
-  face/edge/vertex counts), export, render PNG snapshots and replay reference recipes.
-- **MCP server** `solidcraft-cli mcp`: AI agents model, measure and look at parts headless or
-  in the running app (see below).
-
-## Build and run
-
-```sh
-cargo run --release -p solidcraft -- --sample          # desktop app with a sample part
-cargo run --release -p solidcraft-cli -- commands      # the command registry
-cargo run --release -p solidcraft-cli -- run examples/bracket.json --out bracket.step
-cargo run --release -p solidcraft-cli -- snapshot examples/bracket.json --out bracket.png
-cargo run --release -p solidcraft-cli -- render examples/render-studio.json --out product.png
-cargo run --release -p solidcraft -- part.step          # open a STEP file as a new design
-cargo run --release -p solidcraft-cli -- eval part.step # measure an imported STEP file
-cargo xtask ci                                          # fmt, clippy, tests, assets, layers, wasm
-```
-
-Windows builds: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
-
-On Windows and Linux, SolidCraft detects a connected 3Dconnexion SpaceNavigator or SpaceMouse through its
-multi-axis HID interface. Move the cap to pan and zoom, and tilt or twist it to rotate the 3D view.
-While editing a sketch, the cap pans and zooms without changing the sketch view. The Navigation
-page in Preferences has an on/off switch and a speed control for the 3D mouse. The web app reads
-it too, through the browser; Firefox needs a 3DxWare setting first (see
-[Getting started › 3D mouse in the browser](docs/book/src/guide/getting-started.md#3d-mouse-in-the-browser)).
-
-With 3DxWare on Windows, SolidCraft follows 3DxWare's profile for it when there is one, and
-3DxWare's object mode (tilt to roll, twist to spin) until there is. The mouse-wheel turns that
-3DxWare makes from the cap's motion are ignored, so the view doesn't zoom in steps as the cap tilts.
-
-On Linux SolidCraft reads `/dev/hidrawN` directly, so the logged-in user needs access to the
-device. A udev rule that adds the `uaccess` tag does that, for example
-`/etc/udev/rules.d/70-3d-mouse.rules` for devices with 3Dconnexion's vendor id:
-
-```
-SUBSYSTEM=="hidraw", ATTRS{idVendor}=="256f", TAG+="uaccess"
-```
-
-Older SpaceNavigators use Logitech's vendor id `046d`; add a rule with their product id (see `lsusb`)
-instead of matching every Logitech device. Reload with `sudo udevadm control --reload && sudo udevadm trigger`, then replug the device. The Flatpak
-sandbox does not expose hidraw devices, so the 3D mouse only works with native builds there for now.
-Devices that send all six axes in HID report 1 (some homemade ones do) are recognised from their
-report descriptor, so they work as well.
-
-In the browser: `cd apps/solidcraft-web && trunk build --release --public-url ./` (WebGPU, or
-WebGL2 with `?webgl`; `?sample` opens the sample part).
-
-## Scripts
-
-A script is a JSON list of commands, the same ones the UI runs:
-
-```json
-{"commands": [
-  {"command": "sketch.create", "params": {"plane": "XY"}},
-  {"command": "sketch.rectangle.two_point", "params": {"p0": [0, 0], "p1": [40, 30]}},
-  {"command": "solid.extrude", "params": {"distance": 20}},
-  {"command": "solid.fillet", "params": {"edges": [[0, 0, 10]], "radius": 3}}
-]}
-```
-
-## AI agents (MCP)
-
-`solidcraft-cli mcp` is a [Model Context Protocol](https://modelcontextprotocol.io) server on
-stdio. Headless it runs its own design session; with `--connect 127.0.0.1:PORT` it drives the app
-started with `solidcraft --control PORT`, so you can watch the agent model. Tools:
-`list_commands`, `execute`, `batch`, `inspect_design`, `measure`, `body_topology`,
-`set_parameter`, `screenshot` (returns the image), `export`, `undo`, `redo`, `new_design`, `open`,
-`save`. Tool calls reach files only in the open design's folder (when it lies inside your home
-folder, never home itself or a hidden folder), SolidCraft's recovery folder and folders given with
-`--allow-path DIR`. Claude Code: `claude mcp add solidcraft -- solidcraft-cli mcp`. Details, client
-configuration and an example session: [docs/mcp.md](docs/mcp.md).

-# SolidCraft roadmap
-
-Status as of **2026-10-14**. SolidCraft supports parametric modelling (sketch →
-features → parametric timeline) as an open, pure-Rust, agent-drivable application.
-
-## At a glance
-
-| 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 | **82 / 82 parts match** — [docs/oracle.md](docs/oracle.md): public cases in `tests/oracle/` with analytic (61) or FreeCAD-computed (21) expected values, run by CI on every PR. |
-| 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) |
-
-## Scope (owner decision, 2026-10-07)
-
-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).
-
-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.
-
-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.
-
-## Milestones
-
-| # | 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, 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 | 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; taper handle open), 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 |

-
-## Interactive modelling
-
-- 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.
-
-## 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 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
-
-- 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 perpendicular
-  planar end face at each end. The UI and `solid.fillet` expose `curvature` (alias `g2`); the size
-  is an equivalent circular setback. Curved faces/edges, sloped 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);
-  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 edges (the blends meet in mitres), 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.
-- 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 and spheres (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.
-
-- 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 bridges
-
-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.

-# Design file corpus
-
-Designs saved by older SolidCraft builds. `tests/design_corpus.rs` opens each one with the
-current build and checks that it evaluates as it did when saved (the `.expected.json` next to
-it is `solidcraft-cli eval` of that file by the build that saved it: bodies, volumes, areas,
-world bounding boxes), that it is upgraded to the current file format, and that damaged and
-hostile variants of it never panic.
-
-| File | Saved by | Era |
-|---|---|---|
-| `m0-box-fillet-hole` | 3714342 | M0: sketch, parameters, extrude, fillet, cut |
-| `m0-revolve-primitives` | 3714342 | M0: revolve, primitives, combine, chamfer, timeline edit |
-| `components-arm` | 97d03e3 | components and occurrences: move, copy, Paste New, ground |
-| `joints-hinge` | c2309eb | joints: revolute hinge driven by a parameter |
-| `modern-sheet-metal` | bd98035 | sheet metal contour flange (oracle 72) |
-| `modern-path-pattern` | bd98035 | pattern on path (oracle 53) |
-| `modern-plastic` | bd98035 | shell, lip, boss, rest, snap fit, plastic rule |
-| `naming-split-pieces` | 9a979cf | format 13 names: a slot splits the top; fillet, chamfer and offset face name its pieces by number (`F2:top#2`) |
-| `move-bodies` | 00baf1d | `solid.move` before it could copy: two bodies, one translated in place, one translated and turned 90 deg about Z (no `copy` key anywhere in the file) |
-| `split-body-pieces` | v0.3.2 (07e263d) | a slot along X cuts a block into two bodies; a fillet, a chamfer and an appearance refer to the pieces by body name (`Body1`, `Body1 (1)`) |
-| `issue-489-stacked-join` | v0.6.0 (809ecf7), desktop | a 70 × 84 extrude, then a 70 × 62 strip joined on its top face, sketched partly over the face's projected edges (issue #489; expected values from main at 2880525) |
-| `issue-616-lid-ribs` | v0.7.0 (a9879fa), CLI | a rounded lid with a skirt ring, a window and a slot cut through, then four ribs joined on the plate over the skirt, flush with the window's sides; v0.7.0 displaced the ribs and left a slit through the skirt and plate (issue #616; script `examples/regressions/lid_ribs_flush_with_window.json`, expected values from the fix) |
-
-The scripts that made them are in `scripts/` (`issue-489-stacked-join` was drawn in the desktop
-app and has none; `issue-616-lid-ribs` is made by its regression script). Every flat face of every final body must also take an attached sketch and an
-offset plane; the faces that can't yet are listed with their issues in `design_corpus.rs`.
-
-Never regenerate a file with a newer build: the point is that it was written by the old one. Add new files for new eras instead.

-// SolidCraft's service worker: the web app keeps working offline and updates itself.
-//
-// `cargo xtask web-offline` (Trunk's post_build hook) writes the build into the line below: the
-// version (workspace version + a hash of every built file) and the files to keep, each with its
-// SHA-256, and the same as `build.json` next to it. Files the app only fetches when it needs
-// them (the CJK font) aren't kept: they come from the network. Every download is checked
-// against its SHA-256: a deployment that lands mid-download (another build's `index.html`) fails
-// the download instead of mixing into the kept build. A new build changes this file, so the
-// browser installs the new worker, which keeps the whole new build before taking over.
-//
-// A launch only ever starts a build whose every file is kept, so a half-downloaded update can't
-// break it. It asks for `build.json` (waiting at most NAVIGATE_TIMEOUT_MS): offline, slow or
-// unchanged, the kept build starts; when a new build is deployed, it is downloaded first
-// (waiting at most UPDATE_TIMEOUT_MS; the download goes on in the background after that) and
-// started. When the site has no `build.json` (the app was removed), launches go to the network,
-// the kept build answering when that fails. Each page then gets its files from the build it
-// started (remembered in PAGES), never from another build with a file of the same name.
-//
-// A cache is only deleted when nothing uses it: a download holds its lock (Web Locks, shared,
-// in any tab or worker; the browser releases it when the download ends or its worker stops), and
-// an open page uses the build it started. Then unfinished downloads are dropped, and so are
-// builds replaced by a newer worker (RETIRED). The origin is shared with other apps (github.io)
-// and other copies of this one (the release zip works from any path): only caches named after
-// this worker's path (CACHE_PREFIX…, PAGES) are ever touched.
-//
-// Unbuilt (VERSION "dev", as debug builds get it), the worker retires: it drops what a release
-// build kept and unregisters, so `trunk serve` after `trunk serve --release --no-autoreload`
-// shows the development build. Deploying this file unbuilt switches the worker off for everyone.
