Settle appearance panel scrolling before targeting Search (#6079 )

* claim: #6076 * test(render): settle appearance scroll before resolving Search (#6076) Expanded starter swatches moved under the scenario click while the existing scroll animation was active. Advance 20 deterministic harness frames before resolving the Search handle. No wall-clock sleep, timeout change, assertion deletion or production change. Original native reproduction fails at the empty-state assertion; all 124 scenarios now pass with one pre-existing ignored adhoc entry.
Merge main synchronization into render (#6098 )

-# SolidCraft: instructions for agents
+# SolidCraft — instructions for agents

-SolidCraft is a clean-room, pure-Rust parametric 3D CAD app (sketch solver, feature timeline, B-rep kernel, an egui UI that agents drive). This file is a router: the hard rules, then the skill to read for your task. Humans: CONTRIBUTING.md.
+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.

-## Start here
-Work: ROADMAP.md, "Where help is wanted most" in CONTRIBUTING.md, issues labelled `help wanted`, `good first issue`, `needs-triage`; architecture in `docs/architecture.md`. Act when the code, docs and rules settle a question; ask only when it changes what users see. Local `plan/` notes are optional.
+## 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.

-## Hard rules (what enforces each)
- Independent: never copy another product's code, icons, text or templates; never drive or take data from commercial CAD. `skills/solidcraft-ground-rules/SKILL.md`.
- No GPL/LGPL/AGPL code, not even reading it (OpenCASCADE, FreeCAD, SolveSpace, CadQuery, LibreCAD, QCAD): `cargo xtask licences --check`.
- Every asset is original or openly licensed with a row in ATTRIBUTION.md; read `assets/AGENTS.md` before icon work: `cargo xtask assets`, `cargo xtask icons`.
- Never crash: no unwrap/expect/panic/unsafe in non-test code (unsafe allowlist in crash-safety), errors are `Result`, input is hostile: clippy `-D warnings`, `hostile_params_never_panic`.
- Everything is a command and programmatic calls never open dialogs: `skills/solidcraft-commands/SKILL.md`.
- Layering (geom, sketch/kernel/render, doc, io, engine, ui-egui, apps); only `crates/kernel` uses truck: `cargo xtask layers`.
- One outer UI container, one camera path (`navigation::handle`), colours from theme tokens: `cargo xtask ui-containers`.
- Application code is Rust only and builds for wasm: `cargo xtask wasm`, `cargo xtask web-offline-test`.
- The product name is SolidCraft; the old name lives only in `docs/compatibility.md`.
- Sorted lists (message catalogs, `mod` lines, languages) stay sorted: `cargo xtask lists`. Never edit generated files (`docs/features.md`, `THIRD-PARTY-LICENSES.txt`) in a PR.
- A design-format change is ONE new file in `crates/doc/src/format/pending/`: `scripts/test-format-pending.sh`.
- A command has input and output schemas (will become required; `schema/unconverted.txt` only shrinks): `skills/solidcraft-commands/SKILL.md`.
- New UI strings go in `assets/locales/pending/<slug>.json`, ATTRIBUTION rows in `attribution/pending/<slug>.md`: `cargo xtask lists`.
- A changed default keeps the old behaviour behind a preference and fills the PR's `Changes a default:` line, and no second PR for an issue a lower-numbered one closes: `pr-checks.yml`.
- A regression test goes in the area's existing test file, never a per-bug file (#3226).
- Look at open PRs first, claim with a draft PR (lowest number wins), one topic per PR, never force-push `main`, no pushes just to catch up with `main`: `skills/solidcraft-contributing/SKILL.md`.
- Show observable changes with real screenshots or a recording, captured yourself.
- Run `cargo xtask ci` before every commit, without switching branches while it runs. `cargo xtask skills` keeps this file and `skills/` honest.
+## 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.

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

+## Running and looking at the app
+- `cargo run --release -p solidcraft -- --sample --control PORT` (sample design + control channel).
+  Pick a free port. Without a display, run it under `Xvfb :99` with `DISPLAY=:99`.
+- Drive it with JSON lines on `127.0.0.1:PORT` (see `docs/control-protocol.md`). The first
+  request on a connection carries the launch's token as `"token"`: read it from
+  `~/.local/share/solidcraft/control/PORT.token`, or start the app with
+  `SOLIDCRAFT_CONTROL_TOKEN=$(openssl rand -hex 32)` and send that.
+  - `{"id":1,"method":"engine.execute","params":{"command":"solid.extrude","params":{"distance":20}}}`
+  - `{"id":2,"method":"ui.start","params":{"command":"sketch.create"}}` then `ui.click {x, y}`
+  - `{"id":3,"method":"ui.screenshot","params":{"path":"/tmp/shot.png"}}` then read the PNG.
+- **For UI work, look at the result** (screenshot, read the PNG). Without a window use
+  `ui.render` or `solidcraft-cli snapshot`.
+- Headless: `solidcraft-cli run script.json --out part.step`, `solidcraft-cli eval design.solidcraft`,
+  `solidcraft-cli snapshot script.json --out shot.png`, `solidcraft-cli commands`.
+- Reference tests: `cargo xtask oracle` replays `tests/oracle/*/recipe.json` and compares with
+  each case's `expected.json` (analytic or FreeCAD values; writes `docs/oracle.md`). Expected
+  values never come from a commercial CAD product.
+- Build with `CARGO_TARGET_DIR=<repo>/target`. Windows: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
+
+## Roadmap
+`ROADMAP.md` (committed) tracks status, milestones and estimates. Update it whenever a
+milestone task lands. `docs/features.md` (SolidCraft's commands by area, from the registry) and
+`THIRD-PARTY-LICENSES.txt` are regenerated on `main` after each merge by the Generated files
+workflow; never regenerate them in a PR.
+
+## Lists many PRs add to
+Keep them conflict-free (CONTRIBUTING.md, "Lists many changes add to"): message catalogs sorted
+(`cargo xtask lists --fix`), `mod` lines in their sorted group, the language list English first
+then by id, generated files left to `main`, and a design-format change as one new file.

-### Built-in render resource adapters (personal integration batch, 2026-10-22)
-
-The original adapters in `crates/engine/src/cmd/render/library.rs`, the generated lookup `library_data.rs` and its generator `tools/render-library/generate.py` project the already attributed starter and SELENE resources without replacing their bytes or authoring manifests. The added scalar texture channels, explicit color/V conventions and immutable-source/GPU-payload sharing are original contributor work under MIT OR Apache-2.0. No external code, commercial CAD data or new third-party imagery was imported. Source metadata and the original authoring attribution remain authoritative; pending runtime acceptance is not a photometric or engineering qualification.

 # SolidCraft roadmap

-The short version, for people who use SolidCraft. The detailed developer status (milestone
-tables, limitations, measurements) is in [docs/roadmap-detail.md](docs/roadmap-detail.md).
-
-## What SolidCraft is
-
-SolidCraft is open-source parametric 3D CAD written in Rust. You sketch, constrain, extrude, and
-change a parameter to watch the timeline rebuild. It runs as a desktop app and in the browser
-([try it](https://solidcraft.io/app)), and it has a command-line tool and an MCP server so that
-scripts and AI agents can drive the same commands you use.
-
-## Works today
-
- Sketching with a constraint solver, and the usual create and modify tools.
- Extrude, revolve, loft, sweep, coil, fillet, chamfer, shell, draft, holes, threads,
-  patterns, mirror and split.
- Parameters with units and expressions, and configurations.
- Faces and edges keep their names through edits, so references survive changes.
- Components, assemblies, joints, motion studies and exploded views.
- Sheet metal with flat patterns and DXF export, and a plastic-enclosure subset.
- A Render workspace with GPU rendering, studio lighting, materials and image export
-  (first release in 0.22.0).
- Import and export of STEP, IGES, 3MF, STL, OBJ and DXF, and FreeCAD and Rhino files.
- Autosave and crash recovery, and the browser build of the same app.
-
-The full list of commands is in [docs/features.md](docs/features.md). Release notes for each
-version are on the [releases page](https://github.com/tangency-labs/solidcraft/releases).
-
-## In progress now
-
-Each feature below is a [milestone](https://github.com/tangency-labs/solidcraft/milestones) holding
-the issues for it, so the count shows how far along it is. Counts are as of 2026-10-25, one per
-feature or request. Work merged on a feature branch (`drawings`, `render`) counts as built but
-reaches the app only when that branch merges. They are rough, not a promise.
-
- **[Rendering & materials](https://github.com/tangency-labs/solidcraft/milestone/17)**: in progress, 9 of 34 pieces done, 3 of them built only on the `render` branch and in the app when it merges. The basic Render workspace is already in releases (0.22.0); the interface rework (#6281) and the material and light libraries are what is left.
- **[Drawings](https://github.com/tangency-labs/solidcraft/milestone/8)**: in progress, 3 of 21 pieces built (2 in releases, 1 on the `drawings` branch), and 3 more partly built there (sheets and borders, bill-of-materials types, the paper scene). Not in the app yet: it lands when the `drawings` branch merges. Today you can export the current view as a DXF.
- **[Sheet metal](https://github.com/tangency-labs/solidcraft/milestone/15)**: in progress, 1 of 30 requests done. Flanges, hems, unfold and flat patterns already work; the 30 are extensions, mostly the per-edge flange options (segments, miters, partial flanges, reliefs) and bend allowance.
- **[Sketching](https://github.com/tangency-labs/solidcraft/milestone/14)**: in progress, 12 of 50 pieces done. Dimension types, selection and snapping options.
- **[Solid modeling](https://github.com/tangency-labs/solidcraft/milestone/2)**: in progress, 9 of 50 pieces done. Blends, holes, threads and patterns.
- **[Assemblies & joints](https://github.com/tangency-labs/solidcraft/milestone/3)**: in progress, 4 of 19 pieces done. Joints, motion studies and exploded views already work; placement rules, linked sub-assemblies, fastener stacks and weldment corners are the pieces left.
- **[Import & export](https://github.com/tangency-labs/solidcraft/milestone/5)**: in progress, 7 of 39 pieces done. FreeCAD, SolidWorks and point-cloud import, and mesh export options.
- **[AI agents & MCP](https://github.com/tangency-labs/solidcraft/milestone/18)**: in progress, 2 of 8 pieces done. Agent chat and the MCP server.
- **[Interface, web app & plugins](https://github.com/tangency-labs/solidcraft/milestone/4)**: in progress, 31 of 96 pieces done. Ribbon redesign, navigation, themes, the web app and plugins.
- **[SMLib kernel migration](https://github.com/tangency-labs/solidcraft/milestone/1)**: in progress, 1 tracking issue open. The kernel is moving from truck to NVIDIA's SMLib (usd-brep, Apache-2.0) on the `kernel-smlib` branch; it is not in releases yet. Tracked in [#4012](https://github.com/tangency-labs/solidcraft/issues/4012).
-
-## Next
-
- **[Surfacing](https://github.com/tangency-labs/solidcraft/milestone/16)**: next, 6 of 14 pieces done. Patch, trim, blend and match exist; the rest of the surface toolset is planned.
- **[Manufacturing / CAM](https://github.com/tangency-labs/solidcraft/milestone/9)**: next, 1 pieces tracked, none done. There is no CAM in SolidCraft yet. Send to Slicer and a first toolpath slice are in review; proposals are [#1153](https://github.com/tangency-labs/solidcraft/issues/1153) and [#1621](https://github.com/tangency-labs/solidcraft/issues/1621).
-
-Features are not tied to a release or a date. Work lands in the daily releases as it is finished.
-Anything without a milestone, such as bug fixes, is not a feature and is not listed here.
-
-## How releases work
-
- Releases ship daily, as numbered versions (v0.22.0, v0.22.1) with nightly pre-releases in
-  between. They are delivered through the in-app updater.
- SolidCraft tells you when a newer stable release exists and never updates without asking.
-  Where it can replace itself safely (AppImage, Windows installer and portable builds) there is
-  an **Update now** button; downloads are checked against the release's SHA-256 list. See
-  [updates and privacy](docs/book/src/guide/updates.md).
- Design files carry a format number. A new version opens designs from older versions, but an
-  older version refuses a design saved by a newer one (0.22.0 writes format 35, and 0.21.0 and
-  earlier will not open it). Each release's notes say when the format changed. Keep a copy of
-  an important design before you move to a new version.
-
-## Licence
-
-SolidCraft is licensed MIT OR Apache-2.0, at your option; see [LICENSE-MIT](LICENSE-MIT) and
-[LICENSE-APACHE](LICENSE-APACHE). Versions already released stay available under those licences
-permanently.

 ## Dimensioning and error reporting

- Operation length fields share design-unit defaults and input evaluation, including secondary
-  distances, thin walls, blend controls, sheet/plastic rules, joints and motion keys. Canvas
-  handles and sketch previews use the same lengths as committed geometry. Existing stored
-  millimetre values retain their size when edited in a design using another unit (#3271).
-
 - 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 Dimension takes a line and a circle or arc (#1803): it measures from the line to the
  circle's edge (the gap, 0 when tangent, or how far the edge reaches past a line that cuts
  it), drives it like any other dimension and keeps the circle on its side of the line.
- Sketch Dimension takes a point and a circle or arc, or two circles or arcs (#4064): it
-  measures to the circle's edge (from the point, or between the two edges: the gap, 0 when
-  they touch, how far they overlap, or the narrowest gap between nested circles).
 - 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.

-//! Bringing the window forward when a close stops at "save changes?".
-//!
-//! A close from the taskbar or a window switcher reaches the window while another app has the
-//! focus. The prompt it opens is only seen once the window comes forward, so the window asks for
-//! the focus then. A window the user is already in is left alone.
-//!
-//! winit's Focus asks as an application, which a window manager with focus-stealing prevention
-//! (KWin's default) refuses for a window used before the switch away: it only marks the taskbar
-//! entry. On X11 the request is sent again with the source EWMH gives "direct user actions"
-//! (`_NET_ACTIVE_WINDOW`, source 2), which is what this is: the prompt is the rest of the user's
-//! close. Native Wayland has no way for a window to raise itself, so there the attention request
-//! (xdg-activation) lets the compositor raise it or mark its taskbar entry.
-//!
-//! When: not at once. KWin raises the window, then the taskbar's closing context menu hands the
-//! focus back to the app that had it, a few milliseconds later, and the window would flicker
-//! forward and back. So the window asks once the menu is gone, `FIRST_AFTER` the close. It asks
-//! again only if the focus is taken back right after it came (a slow menu) or never came; a later
-//! switch is the user's own, and the window stays where the user put it.

-//! (`org.freedesktop.appearance color-scheme`, then GNOME's `color-scheme` and `gtk-theme`), the

-//! own: the first reading, then the portal's `SettingChanged` signal; where the signal can't be
-//! had, a reading every few seconds. Without a portal it asks `gsettings` instead, on the same
-//! thread. The window reads the last answer with an atomic load
-//! (`solidcraft_ui_egui::Services::desktop_dark`), and the decision from the raw values is

-//! macOS: what a crash in native code leaves behind (docs/crash-reports.md).
-//!
-//! A crash inside a graphics driver or another library (a segfault, an `abort()`, a stack
-//! overflow) is no Rust panic: the panic hook never runs and the next start only found "an
-//! unclean exit". A signal handler for SIGSEGV, SIGBUS, SIGILL, SIGFPE, SIGTRAP (how a trap
-//! instruction arrives on Apple silicon) and SIGABRT now writes, before the process goes, the
-//! same small JSON file as the Windows filter (`native_crash.rs`): the signal, the faulting
-//! module and the offset into it, and a short frame-pointer walk, next to the run's crash journal
-//! (`solidcraft_engine::crash::native_paths`). The next start puts it into the unclean exit's
-//! report. The signal then goes on to the handler that was there before (the standard library's
-//! stack overflow message) or to the default action, so the process still dies of it and macOS
-//! still writes its own crash report (`~/Library/Logs/DiagnosticReports`; the file names the
-//! `pid` the JSON records).
-//!
-//! Installing a signal handler and asking dyld which image holds an address have no safe API,
-//! hence the `unsafe_code` allowance on this module (the app crate denies it). The handler runs
-//! on a thread that may have a broken heap, or on the small alternate stack after a stack
-//! overflow: it doesn't allocate, formats into a buffer on the stack, and only reads memory on
-//! the thread's own stack. It writes what it knows from the signal first and only then calls
-//! `dladdr` (not on POSIX's async-signal-safe list; it takes dyld's recursive reader lock and
-//! doesn't allocate) to name the modules, rewriting the file, so a hang or a fault in there
-//! still leaves a record.

-# Render workspace icon drafts
-
-All ids below are **Open** for owner review, except `render_scene` and `render_image`,
-which are existing accepted icons used only as references. No commands, toolbar
-entries, browser selectors or runtime request manifests are changed by this draft set.
-`render_remove_override` is the one remaining alias (of `render_from_material`);
-`render_execute`, `render_environment` and `render_fit_product` now have their own
-masters in `design/svg/model/`. Accepted source masters stay unchanged.
-
-Review with `python3 -B assets/icons/ui/design/tools/icon_status.py --serve`,
-search `render_`, and select Open. See [STYLE_GUIDE.md](STYLE_GUIDE.md) for
-acceptance; drafts do not imply implemented commands.
-
-The finished references in each row were read and previewed in both themes
-before authoring. Draft contact sheets (96, 24 and 16 px, both themes) are local
-review evidence, not shipped assets. The icons are grouped in five families, each
-with one shared design rule.
-
-## Lights
-
-Rule: a slate source glyph with light passive fill, 2.55-unit outlines and a dotted
-accent stem (three dots, 4.25 diameter, 7 units apart) showing the direction.
-
-| Meaning | Id | Finished references | Drawing |
-|---|---|---|---|
-| Light area | `render_light_area` | `box`, `camera` | Slanted flat panel on the canonical axes above the dotted stem. |
-| Light spot | `render_light_spot` | `camera`, `material` | Cone with a curved rim above the dotted stem. |
-| Light point | `render_light_point` | `camera`, `material` | Round source disc with a centre dot above the dotted stem. |
-| Sun | `render_sun` | `sphere`, `camera` | Source disc of the same size with eight short radial rays instead of a stem. |
-| Light by highlight | `render_light_by_highlight` | `sphere`, `material` | Shaded sphere with a ringed highlight target; the dotted stem arrives from above. |
-| Solo light | `render_solo_light` | `fit`, `camera` | Point source and stem inside four corner focus brackets. |
-
-## Looks
-
-Rule: the lit look sphere (top-left highlight, bottom-right shade) plus one cue that
-says what happens to it; receiving bodies stay canonical grey or cube shapes.
-
-| Meaning | Id | Finished references | Drawing |
-|---|---|---|---|
-| Appearance | `render_appearance` | `material`, `box` | Shaded look sphere on the top corner of an accent-shaded cube: a look assigned to a body. |
-| Paint | `render_paint` | `material`, `paste` | Flat brush with an accent tip, light ferrule and slate handle. |
-| Pick up | `render_pick_up` | `material`, `copy` | Eyedropper with a grey bulb, slate crossbar and accent sampling tip. |
-| Replace all | `render_replace_all` | `copy`, `box` | Grey sample sphere with an arrow to an accent sphere, beside a second accent sphere. |
-| Copy look | `render_copy_look` | `material`, `copy` | Look sphere in a square frame, offset from a second frame outline. |
-| Remove override | `render_remove_override` | `appearance`, `box` | Alias of `render_from_material`: the custom look is crossed off. |
-| Same look | `render_same_look` | `select`, `box` | Look sphere and three cubes; the two matching cubes are ringed. |
-| From material | `render_from_material` | `material`, `extrude` | Look sphere struck through above a plain grey slab, so the material shows. |
-
-## Studio
-
-Rule: the standard grey cube stands in the set-up it is lit or placed in.
-
-| Meaning | Id | Finished references | Drawing |
-|---|---|---|---|
-| Library | `render_library` | `library`, `copy` | Row of three look spheres, the middle one accent, on a shelf bar. |
-| Lighting presets | `render_lighting_presets` | `new`, `render_scene` | Two stacked cards, the front one holding a light bulb. |
-| Environment | `render_environment` | `environment_map`, `render_scene` | Dome with a grey cube inside. |
-| Ground | `render_ground` | `box`, `render_scene` | Grey cube on a slab with an accent contact patch. |
-| Backdrop | `render_backdrop` | `render_scene`, `render_image` | Grey cube in front of a tall upright accent panel. |
-
-## Camera and shots
-
-Rule: one chunky camera body with a lower-right round badge for shot actions; the
-other camera icons are simple frames.
-
-| Meaning | Id | Finished references | Drawing |
-|---|---|---|---|
-| Shot | `render_shot` | `camera`, `new` | Camera body with a plus badge: save a shot. |
-| Update shot | `render_update_shot` | `camera`, `undo` | Camera body with a refresh badge. |
-| Render all shots | `render_all_shots` | `copy`, `render_image` | Stacked camera bodies with a play badge. |
-| Shots strip | `render_shots_strip` | `camera`, `copy` | Strip of three small frames, the middle one in accent. |
-| Fit product | `render_fit_product` | `fit`, `camera` | Grey cube inside four corner brackets. |
-| Lens / field of view | `render_lens` | `camera`, `fit` | Concentric lens rings around an accent centre. |
-| Exposure | `render_exposure` | `material`, `environment_map` | Disc split light and accent, with plus and minus marks. |
-| Aspect frame | `render_aspect_frame` | `render_image`, `fit` | Wide rounded frame with two opposite corner brackets. |
-| Frame guides | `render_frame_guides` | `render_image`, `fit` | Rounded frame with a rule-of-thirds grid and four accent nodes. |
-
-## Output and result
-
-Rule: one picture base (frame with landscape) with a lower-right round badge; the
-size, background and quality icons draw their own simple subject.
-
-| Meaning | Id | Finished references | Drawing |
-|---|---|---|---|
-| Render image | `render_execute` | `render_image`, `camera` | Picture with a play badge: create a rendered image. |
-| Render output size | `render_output_size` | `render_image`, `fit` | Picture frame with a diagonal double-headed dimension arrow. |
-| Transparent background | `render_transparent_background` | `material`, `render_image` | Grey cube on a checker tile. |
-| Quality | `render_quality` | `list`, `library` | Three rising bars, the tallest in accent. |
-| Check render | `render_check` | `render_image`, `new` | Picture with a check badge. |
-| Cancel render | `render_cancel` | `render_image`, `delete` | Picture with a square stop badge. |
-| Export image | `render_export_image` | `render_image`, `copy` | Picture with a large outward diagonal arrow at the upper right. |
-| Compare | `render_compare` | `render_image`, `material` | Two grey pictures split by a vertical slider with opposed arrows. |
-| Results | `render_results` | `render_image`, `copy` | Stack of two pictures, the front one showing a landscape. |
