-# 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 gives its class the icon the taskbar falls back
+  on) 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.
+
+- Keep the `Changes a default:` line in the PR description filled in, and don't open a second PR for
+  an issue a lower-numbered open PR already closes; `pr-checks.yml` fails both (CONTRIBUTING.md, "Sending a change").
+
+## 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.
+New UI strings go in a new `assets/locales/pending/<slug>.json` and new ATTRIBUTION.md rows in a new
+`attribution/pending/<slug>.md`, never into the catalogs or the table (see the README in each folder).

 # 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).
+Status as of **2026-10-14**. SolidCraft supports parametric modelling (sketch →
+features → parametric timeline) as an open, pure-Rust, agent-drivable application.
 
-## What SolidCraft is
+## At a glance
 
-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.
+| Question | Answer |
+|---|---|
+| Where are we? | **M0 and M13 done; M1, M2, M5–M7, M9, M10, M14 in progress.** Sketch with solver and the full SKETCH create/modify set; extrude, revolve (two sides, symmetric, to object), fillet/chamfer (variable radius, chord length, a radius per edge, corner patches), holes, threads (cosmetic and modelled), patterns, mirror, shell (inside/outside/both), draft, loft, sweep, coil, split body and split face, delete face, construction planes, axes and points; persistent naming of faces and edges; parameters and configurations; components, joints, motion studies, exploded views; sheet metal and a plastic enclosure subset; STEP/IGES/3MF/STL/OBJ/DXF; FreeCAD/Rhino import; autosave and crash recovery; desktop and browser (wasm) app, CLI, MCP server. |
+| Features | Every registered command by area — [docs/features.md](docs/features.md) (`cargo xtask features`); registry breadth does not establish workflow or geometric depth |
+| Reference tests | [Current case count and results](docs/oracle.md): public cases in `tests/oracle/` with analytic or FreeCAD-computed expected values, checked by the reference-test job in [CI](.github/workflows/ci.yml). |
+| Tests | Solver, profiles, kernel booleans/blends/measures, expressions, timeline, persistent naming, file formats and migrations, assemblies, sheet metal, engine end-to-end, hostile-input fuzz over every command and headless UI scenarios. `cargo xtask ci` reports the current passing counts. |
+| Gates | `cargo xtask ci`: fmt, clippy -D warnings, tests, asset attribution, layering, wasm32 build — green |
+| Time to a useful alpha (M0–M6) | ≈ **82 agent hours** remain (sum of the M1–M6 estimates below) |
 
-## Works today
+Optional GPU viewport ambient occlusion is available in View settings and Graphics preferences,
+with persistent settings, Performance/Quality graphics presets (Quality combines AO, Fine tessellation and adaptive 2× supersampling; manual combinations show Custom), and the
+`view.ambient_occlusion` and `view.graphics_preset` commands. See [display settings](docs/ambient-occlusion.md).
 
-- 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.
+## Scope (owner decision, 2026-10-07)
 
-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).
+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 progress now
+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.
 
-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.
+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.
 
-- **[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
+| # | Milestone | Status | Hours left |
+|---|---|---|---|
+| M0 | Vertical slice | done | — |
+| M1 | Sketch depth: command coverage implemented — projection/intersect/include as linked geometry (auto-project on faces, lost-reference warnings, break link), full SKETCH create/modify set (slots, polygons, tangent arcs/circles, ellipse, fit/control splines, conic, text, trim/extend/break, fillet/chamfer, offset, mirror, patterns, move/scale, blend curve, centerline), constraints incl. curvature and polygon with over-constraint refusal, Shift-picked line midpoints in Horizontal/Vertical using persisted points and ordinary constraints (#2087), driven/arc-length/linear-diameter dimensions, AutoConstrain, DXF/SVG insert, 3D sketch curves (Project To Surface, Intersection Curve, Isoparametric Curve, Spun Profile), exact free-form profiles (B-spline/NURBS edges, any spline degree, curves cut by crossings), sweeps and pipes along 3D sketch curves, canvases and decals, curvature combs. Exact free-form Extend and certified associative offsets now preserve geometry and IDs through edits, deletion and reopen. Occurrence-frame 3D wires now store explicit coordinate spaces and retain points and analytic fits through moves, refresh, undo and reopen. Constructive sketch solving (Owen 1991, Fudos & Hoffmann 1997) ahead of the numerical solver: points and rigid clusters are placed on the branch the sketch had, so dimension edits and drags keep their solution; edits that would turn a sketch over are refused; drags re-solve only the sketch per frame. Remaining workflow repairs: mixed offset junctions, legacy natural-spline seams, and damaged legacy wire links lacking frame provenance | in progress | 4 |
+| M2 | Robust modelling: coplanar booleans in the kernel, holes (placed on faces, at distances from reference edges, and on sketch points), threads (cosmetic, then modelled), patterns, mirror, shell, draft, split, construction geometry | in progress | 16 |

+| M3 | General fillets and chamfers (curved edges, chains, vertex blends); saddle rolling-ball surfaces now use continuous seam sections and arc-length fitting with shared contact boundaries and bounded accuracy checks; tiny rim edges remain selected instead of nearby wall seams when filleting (#2498) | in progress | 30 |
+| M4 | Files: STEP import (done — [docs/step-import.md](docs/step-import.md)), FreeCAD/Rhino solids through cadmpeg (done, desktop, browser 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; responsive feature history with width-driven icons/names/title, snapping width resize, bottom/left/browser-stack docking, shared-column collapse, rollback bar, multi-selection and persistent folders), right-docked dialogs (done), live previews for every feature dialog (done), keyboard-first commands with on-canvas value boxes and sketch inline dimensions (done), drag manipulators with automatic join/cut (done: extrude incl. two sides, fillet, shell, hole depth, move, pattern spacing, revolve rotator, extrude taper), dark theme (done), right-click menu with Repeat (done), measure tool (done), section analysis (done), selection filter (done), drag-solve of sketch points (done); appearance controls now preserve body/face/component targeting, named transparent looks, reuse/search and override removal; Browser Expand All / Collapse All (`browser.expand_all`, `browser.collapse_all`) on the design and component menus; preferences | in progress | 6 |
+| M7 | Thin extrude (walls along open or closed curves: centre, inside, outside or two sides; mitred corners, crossing walls joined; #721), sweep, loft (incl. to a point), rib and web (to next / depth), emboss (planar faces and exact radial emboss/deboss of bounded orthogonal profiles on complete exterior cylinders/sleeves), thread (cosmetic, and modelled M3–M20 outside and inside: the ISO profile screwed in as a faceted cut), coil (smooth B-spline helical walls), pipe, pattern on path, patterns of bodies and components, replace face (parallel), align, remove, feature copy/paste: done. Unique eligible cylindrical targets are inferred for new Emboss features. Left: general curved-face emboss and exact (unfaceted) modelled threads | in progress | 12 |
+| M8 | Surface workspace (#772). Done: Patch (sketch regions; edge loops filled G0, plus `crown`), Stitch, Thicken (planes and cylinders), Extend (straight edges of planar surfaces), Trim (by a plane, a face or sketch curves swept onto the surface, keeping a side or the picked regions; mutual trim of two surfaces, extended to meet and stitched, #767), Delete Face (healing), Boundary Fill, zebra/draft/curvature-map analysis, Surface Extrude/Revolve/Sweep/Loft from open and closed curves, Offset, Unstitch and Reverse Normal; the continuity-driven core (`kernel/src/bridge.rs`, G0–G3 Hermite rows) with **Blend** (`surface.blend`, #764: edge chains along one or several faces, closed rims paired seam to seam or from picked seams, a dialog), **Match** (`surface.match`), **Boundary** (`surface.boundary`, #763 — two sketch curves exact with G0–G3, three or four as the flat patch of their loop, and curve networks: Coons and Gordon surfaces through sketch, 3D-sketch or edge curves, a point for a three-sided side, G1/G2 against the faces along one direction's edges, joined into their body on request; G1/G2 on two sides that meet at a corner waits for the Gregory-type corner), **Fair** (`surface.fair`, CV fairing), **continuity analysis** (`inspect.continuity`, #770; a toolbar tool with edge markers and a legend, and curvature combs along face isocurves) and a multi-section **loft** with per-end continuity and crown, and guide rails on solid and surface lofts (one or two, scaling or stretching the sections between; #201). Also in the Class-A pass: G1…G4 blend curves in the sketch, chord and variable-radius fillets on curved edges (with honest refusals where the fit cannot hold), and a G2 corner patch where filleted edges meet (kernel; the command refuses until the patch's sections can be sewn to the blends' contacts).

+| M9 | Components and assemblies: New Component / Create Components from Bodies, active component, per-component origin/bodies/sketches/timeline entries, occurrences with transforms, Copy/Paste vs Paste New, nested Browser tree with visibility and isolate; Ground, Move/Copy of occurrences, joints (rigid, revolute, slider, cylindrical, pin-slot, planar, ball) by joint origins with limits and Drive Joints, closed kinematic loops (four-bar, slider-crank: the loop's other joints follow the driven one on its branch, and driving stops where a loop can no longer close), cams (`joint.cam`: a revolute cam drives a slider or revolute follower along a closed sketch profile or the cam's edges, knife, roller or flat followers, worked out again when the profile changes; drives, studies, closed loops, contact sets), As-built Joint, Rigid Group, Contact Sets (driving and motion studies stop where bodies in a set would pass through each other), Motion Study (joint values keyed along a timeline, playback, export of occurrence positions as JSON/CSV), motion analysis (joint values and a point's path charted over a study as value, velocity and acceleration; the parts that collide along a study, with the steps where they do), Exploded views (automatic or by hand, shown without changing placements, and exported as an animation coming apart and back together); interference, per-component physical properties; STEP with assembly structure; URDF export for robot simulators (links with meshes, mass and inertia; joint chains whose values match Drive Joints; docs/urdf.md). Physical properties now measure material-aware component/occurrence placements, descendants and repeated instances, including pending moves and body reassignment offsets; contact geometry and automatic exploded centres respect those offsets. Groundwork done: component tree, occurrences with transforms (instances, Paste New), world placement, active component as authoring frame, ground, Capture/Revert Position, moving bodies and sketches. UI: ASSEMBLE panel dialogs for New Component, Joint (snaps on faces, edges, circles and vertices; animated motion preview; offsets, flip, limits), As-built Joint, Joint Origin, Rigid Group, Drive Joints (live slider), Motion Link, Cam and Interference (overlaps shown red); joints in the timeline and the Browser | in progress | 32 |
+| M10 | Sheet metal: flange (base, edge, contour), hem, unfold/refold, convert, flat pattern + DXF, rules: done. PLASTIC enclosure subset: Boss, Rib, Web, Lip/Groove, Snap Fit, Rest, Plastic Rules (library, edit, assign; rule draft and clearance as feature defaults): done, tested against hand-computed geometry. UI: SHEET METAL and PLASTIC tabs with dialogs (live preview, Edit Feature, pre-selection) for Flange, Hem, Unfold/Refold, Convert, Sheet Metal Rules, Create Flat Pattern (flat view with bend lines, bend table CSV/JSON and DXF export with exact circle/arc/line cutouts), Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Fold (bend along a sketch line); flanges meeting at a corner closed at any angle with the rule's gap; edge flanges with their own angle and height per edge in one feature; corner reliefs (notch, round, rectangular, tear) chosen by the rule; Convert to Sheet Metal from a solid or shelled body by its bend edges (flat faces, sharp bends) | in progress | 36 |
+| M11 | 2D drawings | deferred | — |
+| M12 | Release: cross-platform packages, verification and deliberate publication implemented; original current-UI demo refreshed. macOS Developer ID signing and notarization are in the release workflow (#5749; they switch on when the Apple secrets exist). Windows installer signing and broader performance work remain | in progress | 16 |
+| M14 | Configurations: a table of rows (parameter expressions and feature suppressions per row) switched with config.activate (undoable, all or nothing), kept through parameter renames and feature deletes (config.configure, config.table, config.column/row/activate). Per-row body materials and appearances (library looks, custom colour/opacity and clearing overrides), undoable activation and save/reopen: done. Ordered typed configuration rules, atomic validation and structured rule editing: done. Component appearance and certified semantic face style columns, atomic preview/apply and independent-copy remapping: done. Exact constructed sketch-side and immutable imported-face lineage now preserve legacy names and reject retargeting. Left: ambiguous shifted/two-sided caps | in progress | 4 |
+| M13 | Never lose work: atomic saves (temporary file, flush, rename; a crash at any moment leaves the old file or the new one) with the replaced version kept as `<file>.bak`; autosave of unsaved changes to the recovery folder every 5 minutes (preference) and after big operations, only when something changed; "Recover unsaved design?" on the next launch (`doc.recovery_list`, `doc.recover`, `doc.recovery_discard`); a kill-mid-save test (process killed while saving a 0.5 MB design 25 times). File format: `"format": "solidcraft/12"`, older formats upgraded step by step (`doc::format`), newer ones refused with a message, out-of-range numbers and broken placements refused; a corpus of designs saved by M0, components-era, joints-era and current builds (apps/solidcraft-cli/tests/corpus) that must open and evaluate as saved; damaged and hostile variants (truncation, bit flips, hostile values, removed keys, repeated features, deep nesting) never panic | done | 6 |
+| M15 | Frames and weldments (#4003): structural members along 2D and 3D sketch lines, butt and mitre corners, trim to faces and bodies, end caps, gussets, cosmetic welds and a cut list. Done: the profile library (`frame.profile.list`, `frame.profile.properties`, `frame.profile.insert`): bar, round bar, rectangular and round tube, angle, channel and I-beam, each SolidCraft's own parametric definition with exact fillet arcs and exact section properties (area, centroid, second moments), tested against hand-computed values; members (`frame.member`): one body per straight line of a 2D or 3D frame sketch, following parameter edits, with a built-in profile (its dimensions parameter expressions) or a profile sketch (its drawn material by alternating nested loops), anchor, angle and mirror; each member's name kept with its line. Left: corners, trims, end caps, gussets, welds, cut list, FRAME tab and dialogs | in progress | 60 |
 
-- **[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).
+M6 navigation preferences include **Touchpad**: Shift + pointer movement pans, Alt/Option +
+pointer movement orbits without a mouse button, and vertical scrolling zooms. Other presets
+retain their saved two-finger scroll preference; camera motion is available through
+`view.navigate` and modifier-aware `ui.move` automation.
+With the **Fusion** preset and two-finger pan enabled, two fingers pan and Shift + two fingers
+orbit freely, with pinch zoom and mouse bindings unchanged. The shared navigation handler
+applies the same gestures to model and Render views and blocks orbit on flat pages.
 
-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.
+UI redesign (#2016): the File/start view (#2027) uses shared light/dark navigation,
+action tiles, recent rows and sample cards, with recovery review and Save As/Export
+entry points. Document loading, sample caches and recovery safety retain their
+existing command paths.
 
-## How releases work
+M11 precursor: File → Export Current View as DXF exports shown placed bodies and sketches from the current
+camera as a 2D millimetre drawing, with hidden edges omitted or dashed. Vector occlusion splits
+partly hidden edges and includes curved silhouettes. Repeated part meshes and triangle
+hierarchies are shared; bounded desktop preparation and occlusion use up to eight workers.
+Curves are approximated; drawing sheets,
+annotations and exact projected curves remain deferred. See [view DXF](docs/view-dxf.md).
 
-- 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.
+Drawing foundations: [RFC #860](https://github.com/tangency-labs/solidcraft/issues/860)
+and the [foundation ledger](docs/drawing-foundations.md) track the bounded implementation
+packages. The first geometry increment defines validated section records in a plane-local
+frame; the ledger separates that contract from section producers and the Drawing workspace.
 
-## Licence
+Desktop view DXF export runs in the file-operation worker with five-stage progress and
+cooperative cancellation. Curve tolerance (0.0001–1 mm, default 0.01 mm) is remembered alongside
+the hidden-edge setting. Cancelled exports preserve the model and the previous destination;
+completed drawings publish atomically. The browser still exports synchronously.
 
-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.
+## Interactive modelling
 
-## How to follow along
+- Modelled threads preview their cut before OK using the background worker on desktop.

+- Thread resolves a suggested metric size when a cylindrical face is picked. Diameter and
+  pitch selectors expose the existing metric designation parameter; custom designations stay
+  editable, and Automatic size returns to the face's suggestion. Cosmetic/modelled and
+  full/partial-length options remain available. This does not add tolerance classes or
+  left-hand threads.
+- New Body extrusion and face-offset previews show completed intermediate geometry while a
+  drag continues, then catch up to the exact final value. Changes to the selected geometry,
+  operation or feature still discard obsolete results. Distance arrows and their value boxes
+  follow the current frame's input.
+- Large fine modelled threads use pitch-based helix resolution and tighter faceted
+  reconstruction fallbacks, preserving thin crests and closed shells on large shafts.
+
+## 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
+
+- Original starter appearances (#1722): 34 opaque recipes through existing commands, with six explicitly unavailable glass recipes and preserved legacy looks; see [the contract](docs/render-starter-appearances.md).
+
+- Bounded linear film accumulation (#1696) supplies caller-admitted mean/variance storage and complete-pass views; actual progressive consumers remain separate. See [the film contract](docs/render-film.md).
+
+- Definition-local visual mapping (#1214) supplies a bounded numerical frame, physical repeat coordinates and a deterministic one-time grain-axis suggestion. It adds no saved record or texture consumer; see [the mapping contract](docs/render-visual-mapping.md).
+
+- 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
+
+- 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 Create groups drawing variants under Line, Rectangle, Circle, Arc, Slot,
+  Polygon and Spline. Each open part remembers its last interactive choice per family
+  across sketch sessions and document-tab switches; closing the part resets these UI choices.
+- Inscribed, circumscribed and edge polygon tools preview their actual outline before
+  placement, including orientation and the selected side count.
+- Construction (X) preserves the active sketch drawing tool, picked anchors and inline
+  dimension values, so line type can change while a shape is in progress.
+- Planar sketch construction previews and hover feedback keep the same dashed pattern as
+  committed geometry; centerlines retain their dash-dot pattern.
+
+- Point has a default Sketch CREATE toolbar button alongside the existing drawing tools.
+  Saved custom layouts are preserved; Reset Toolbar restores the default Point button.
+- Construction planes cannot take an origin-plane name (XY, XZ, YZ, Top, Front, Right). Plane
+  arguments reject such a name when an older design's construction plane already has it. Use
+  the other alias, the construction feature's numeric ID or an explicit plane; existing
+  stored references keep their saved meaning. Section Analysis uses the same check.
+- Sketch text can be edited from a letter interior or outline's context menu or the Edit Text command.
+  Interior selection requires every profile boundary to belong to the same text source;
+  the editor highlights the whole source without replacing profile selections.
+  Content, baseline X/Y, height and rotation update the original text source in one undo step;
+  cancelling or rejecting an invalid value preserves the sketch. Position and height fields
+  use the document units captured when editing starts; generated outlines remain associated
+  with their text source, and untouched inputs preserve their saved internal values.
+  Dragging a text outline moves the entire source in one undo step; Escape restores the
+  gesture. Move/Copy on a selected text outline provides unit-aware X/Y distances and rotation
+  about its baseline; copies keep an independent editable text source.
+- Repeating the initial point of a planar multi-point sketch drawing tool is neutral: the tool
+  waits for a distinct point without a degenerate-shape error or history entry. Typed input
+  and programmatic commands retain their validation.
+- Circular-pattern and angled-plane axes reject explicitly supplied malformed or expression
+  origins instead of silently rotating about zero. Numeric origins remain in millimetres;
+  associative axis expressions and construction-axis references remain unsupported.
+- Single-line and rectangle-side dimensioning supports selecting a line or its two endpoints.
+  Type a value and press Enter to commit one undo step; rejected values remain editable and
+  cancellation leaves the sketch unchanged. Fit keeps geometry clear of the Sketch Palette
+  and navigation controls, including enlarged displays and nested pending placements.
+- Sketch Dimension takes a line and a circle or arc (#1803): it measures from the line to the
+  circle's edge (the gap, 0 when tangent, or how far the edge reaches past a line that cuts
+  it), drives it like any other dimension and keeps the circle on its side of the line.
+- Sketch 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.
+  Component/canvas distance controls, sketch cursor coordinates, flat-pattern dimensions
+  and pocket depths, interference volumes and parts-library lengths also use design units.
+- Curvature and Polygon constraints accept complete preselected operands. Fix/Unfix
+  consumes complete point/curve selections consistently; mixed or ambiguous selections
+  retain the picking workflow. Rejected constraints preserve selection and undo history.
+- Contextual error reporting: a **Create Issue** action beside feature errors opens a
+  reviewable GitHub issue draft with the error, operation settings, build diagnostics and
+  useful reproduction context. The draft is editable, with optional capture of the actual
+  viewport and copy/save controls. Opening GitHub does not submit the issue. Help also exposes
+  reporting for unexpected results that did not produce an error.
+- The header exposes **Report a bug**, including an accessible compact control on
+  narrow windows. It opens the same editable report and screenshot review without
+  changing the active model or a pending dimension.
+- Crash reports: every panic (in a command, in the kernel, anywhere else) and every unclean
+  exit (abort, stack overflow, kill: found at the next start through a locked per-run command
+  journal) leaves a local report with the backtrace, version and commit, the command and the
+  design that reproduce it (`solidcraft-cli crashes replay <id>`). Repeats are counted, not
+  rewritten; at most 20 reports, 50 MB and 90 days. The app shows them after a crash (Help >
+  Crash Reports…) with a reviewed issue draft; agents read them through
+  `diagnostics.crash_reports`, the MCP `crash_reports` tool or the CLI. Nothing is sent
+  anywhere. See [crash reports](docs/crash-reports.md).
+- Agent chat (off by default, desktop): a side panel that drives a coding agent the user
+  already has (Claude Code through its ACP adapter, Codex, Gemini CLI, OpenCode, Grok Build, …) over the
+  Agent Client Protocol, under the user's own login; SolidCraft stores no keys. The agent works
+  through SolidCraft's MCP tools on a gated endpoint of its own: file actions wait for Allow or
+  Deny, crash reports are off limits, 24 changes per message, one undo step per message, and
+  the agent's whole process group ends with the panel or the app. Docks left or right,
+  minimises to a strip. Grok Build discovery includes `~/.grok/bin` and reuses the user's
+  Grok login. See [agent chat](docs/agent-chat.md).
+- Command scripts from designs (#886): `timeline.export_script` (CLI `solidcraft-cli script`)
+  writes a design's history as a script that `eval` and `run` replay into the same design —
+  user parameters, units, sheet metal and plastic rules and materials as their own commands,
+  then each feature through `timeline.add` with its ids, names and dimension parameters kept,
+  so every feature kind replays exactly and a failing feature fails the same way. Trimming the
+  script after a step gives the design at that step. Appearances, folders, views and
+  configurations are listed as left out; components and joints are not supported yet.
+
+## 0.2.0 release batch
+
+- Includes the new axis navigation, adaptive sketch drawing/picking, origin-corner repairs,
+  durable supported profile/face references, endpoint dimensioning and contextual reporting.
+- Smooth ruled-wall display joins are hidden only within the supported geometric certificate;
+  authored splits and actual creases remain protected. Wireframe retains physical edges.
+- Paste New uses a bounded current-geometry comparison for supported convex line/circle
+  prisms with separated circular holes; unsupported shapes retain the existing strict check.
+- Common-bore Union retries check additional boundary curves before recutting the bore,
+  preventing the reproduced thin-web loss. Unknown additional trims refuse; inherited
+  common-cylinder trims retain their existing policy, so this is not a general Boolean proof.
+- Exact full-path assembly joint editing remains separate work and is not part of this batch.
+- Stable 0.2.0 is published: all release payload checksums, native cold reopening, deployed
+  web app and both Flatpak architectures were verified. The replacement README demo uses
+  the original electronics enclosure story and animated pointer in the actual English
+  0.2.0 UI, at 4× playback. Publication follows [the release workflow](docs/releasing.md).
+
+## 0.2.1 critical fixes
+
+- Separated multi-profile Join/Cut extrusions into one solid target batch their tools using
+  conservative construction bounds, avoiding a Boolean rebuild for every profile. Live
+  extrusion previews build only their tools; confirmation validates the final Boolean.
+- Coplanar selected body faces share one linked sketch and one extrusion. Automatic Join/Cut
+  keeps the evaluator's participant scope, including parts of an empty imported component. Desktop OK/Enter
+  computes on a scratch session in the background, with atomic acceptance and cancellation.
+  Planar section stitching projects lines/arcs analytically and removes duplicate endpoints.
+- Imported rotated face groups can check all full start-face seams in one guarded
+  construction. Separated tools may batch a Join when each meets the same single body;
+  nearby uninvolved bodies retain the original contact decisions. Regression comparisons
+  cover all four extrusion operations.
+- Inward multi-face cuts retain every eligible target and subtract separated tools together.
+  Safe interior classification handles roundoff at shared imported line/arc endpoints.
+  Straight extrusion feedback caches existing face/profile triangles and updates the display
+  directly, including a newly opened STEP's single identity component placement; other
+  extents, moved or repeated components and curved sketch profiles keep the Engine preview.
+- The extrusion fixes retain tracked Boolean history and the current `solidcraft` packages.
+  Confirmation and tool previews use main's shared background calculation. Main's collapsed
+  blend-wall refusal and its tests are retained, including smaller valid radii and mirrored parts.
+- Axis view and navigation controls stay anchored to the viewport when feature dialogs or
+  the command palette open, at normal and enlarged display scales. Fit still accounts for
+  dialog coverage; covered controls do not receive clicks through dialogs.
+- Eligible planar faces survive fillet, chamfer and shell operations with exact source
+  certificates. Sketches placed directly on the enclosure wall and inner floor follow
+  width and wall changes, including after the USB cut and cold reopening.
+- Remove artificial straight-wall and rounded-corner subdivisions left by shell and
+  extrusion cuts. Identical generated wall segments span adjacent slabs as one physical
+  face, with exact full-height supports and boundary stitching. Preserve authored face
+  splits and face appearances. Permanent regressions cover material, STEP, reopening and
+  unaffected bodies across the extrusion end plane.
+- Feature dialogs use the available screen height for their fields, with OK and Cancel
+  outside the scrolling region, including enlarged display scales.
+- Design format 13 records shell-face attachments. Older designs remain readable;
+  newly saved designs require 0.2.1 or later. Ambiguous or unsupported faces still refuse
+  attachment rather than guessing a plane.
+- Saved projections from a removed strip retain their geometry and report the lost
+  reference. Explicitly reselect the wall to repair that projection.
+
+## Workspace layouts (#2029)
+
+- General preferences save Floating or Compact using the universal UI containers.
+  Compact joins the workspace selector and ribbon, docks the content-hugging Browser
+  flush beneath them with a square join, and opens tool sheets below the compass.
+  Sheets remain draggable, rounding all corners away from their right dock; footer
+  backgrounds follow the same corners. A separate preference hides ribbon icon labels
+  for a shorter ribbon in either layout.
+  Assistant keeps the outermost edge and History keeps its chosen dock. Switching
+  retains the active tool, camera, selection and design; system windows and menus
+  keep their existing behavior.
+
+## View navigation
+
+- Navigation has an opt-in Free orbit preference for mouse and 3D-mouse rotation through
+  both poles with roll. It defaults off, preserving existing preset snapping and pole limits.
+  The SolidWorks face menu offers Normal to Selection (`view.normal_to`), shared with Look At
+  and Ctrl+8, including repeat-to-flip, preserving scale and projection.
+
+- Desktop Ctrl/Cmd +/- and 0 change or reset the saved UI scale. The scale slider keeps
+  its layout stable during a drag and applies the selected scale on release.
+
+- OpenSCAD navigation preset: left drag orbits, right/middle drag pans, Shift+right/middle
+  drag zooms, and the wheel zooms. Available in the shared desktop/web Navigation preferences.
+- Compact clickable signed X/Y/Z axis tips, smooth drag-to-orbit, and Shift-orbit snapping
+  to 26 standard and diagonal views. Pointer motion accumulates independently of a lightly
+  damped spring, with a boundary margin to prevent flicker. Z-up/Y-up and the nearest square
+  top/bottom heading are preserved. Diagonals include 45-degree edge and isometric corner views.
+
+## Known limitations
+
+- Scheduled and manual CI scan locked dependency advisories, bans and sources with
+  cargo-deny. Vulnerabilities fail the scan; unmaintained crates warn. Local vendored
+  patches require separate upstream review because advisory databases cannot version-match
+  their path dependencies. Pull requests retain the existing licence checks.
+
+- Associative shell-face sketches require a unique certified planar source. Nested shell
+  attachments and ambiguous coincident sources remain unsupported.
+- G2 fillets: exact quintic blends of straight edges between planar faces, with one planar
+  end face at each end, including sloped ends (#2708). The UI and `solid.fillet` expose
+  `curvature` (alias `g2`); the size is an equivalent circular setback. Curved faces/edges,
+  multi-face ends and corner junctions remain unsupported.
+- Fillets and chamfers: constant, variable-radius and chord-length fillets; a radius per edge,
+  rounds next to earlier rounds of another radius, and smooth corner patches where three rounds
+  meet (a sphere for equal radii); perpendicular corner fillets after a closed ring of earlier
+  rounds preserve the ring's radii and the enclosed planar face (#1557);
+  mitres between separate rounds of the same radius keep their endpoint tangent, so a later
+  fillet can select an upright and its adjoining bottom mitre as one chain (#2422);
+  straight edges (convex or concave) between planar faces with perpendicular
+  planar end faces (equal-distance chamfers also meet sloped planar end faces, including inner
+  basin rims within the rim width); convex fillets also meet sloped planar ends and reflex
+  corners around pocket rims, with unequal wall slopes and extensions confined to the face;
+  connected equal-distance chamfers also trim each other across unequal sloped rim walls;
+  curved chamfer chains with straight planar ends can terminate across two existing planar
+  bevel faces, splitting their shared seam; picks on the same tangent chain are applied once (#1303);
+  whole smooth loops of a planar face, picked whole or by one edge (tangent
+  chain), including circles and walls at any angle (boss bases and tops, bores, pocket floors,
+  plate outlines), loops with sharp corners between straight or mixed arc/line edges (straight
+  blends meet in mitres; perpendicular curved walls use offset intersections, with D-rim removal
+  checked within 0.1% of analytic offset slices), runs of
+  neighbouring edges along a planar face's loop (two top edges of a box: mitred, ending square;
+  with the edge between them too, the corner becomes a sphere octant),
+  rounded corners rounded again (sphere octants, tori at concave corners); every edge of a
+  convex planar body or of an extruded part; fillets inside patterns; closed chains of curved
+  edges between any two smooth sides (a branch pipe on a main pipe), by a rolling ball (the
+  blend a rational B-spline through exact arcs), closed or ending at planar faces square to the
+  edges, where straight or curved cap edges are trimmed to the contacts (the straight edge
+  between two overlapping extruded arcs); knife edges, where the two faces have opposite
+  normals (a wall that runs out tangent into a face: the ball that fits there); an edge that
+  runs out along an end face tangent to one side (the arc top edge of that wall), cut where the
+  blend meets it; rounds that end in an earlier round on curved faces, in any order (the rounds
+  of two edges at a vertex meet in a crease, as on a box), picked together or one after the
+  other, except a round after a round of the edge between the wall and a flat face that it
+  would run over; the three edges at a vertex of any smooth faces, of one radius, end in a
+  piece of sphere. A limiting blend that collapses a side wall into coincident boundary
+  curves is refused as too large rather than returning an unmeshable face (#1113).
+- Booleans: prisms along one direction (plates with holes, slots, patterns of them, equal
+  sections stacked end to end) are combined exactly in 2D. Qualified axial cuts preserve
+  annular holes with overrun cutters, including inward Press Pull after a joined extrusion;
+  curved wall qualification rejects false transverse axes instead of filling holes.
+  Bodies touching along one whole face
+  (a part and its mirror image) are stitched; coincident planar faces are pushed apart when
+  their neighbours are planes or cylinders. Other coincident curved configurations can still
+  fail. Bounded containment classification preserves fully internal cavities and nested
+  material islands independently of shell order, with STEP round-trip and material-membership
+  regressions. Near-contact curved shells use the general boolean path rather than a
+  containment shortcut. Spheres are built from six pole-free patches.
+- Mass properties come from fine tessellation (curved faces within ~1e-4 relative); triangles
+  that cut through curved faces (trimmed faces after booleans) are split onto the surface first.
+- STEP import (our own reader, crates/kernel/src/step_in) reads solids (B-rep with analytic and B-spline geometry), units,
+  product names, colours and assemblies; analytic offsets on planes, cylinders, cones, spheres
+  and regular tori are read exactly (signed/nested distances, units and face sense). Freeform
+  offset surfaces and pcurve-only edges are not read yet,
+  and assembly components are flattened into bodies. Closed periodic faces (torus, B-spline
+  bands) are split in two for meshing; measure() uses a finer tolerance for small radii.
+- Persistent naming follows the kernel's exact face history (docs/book/src/dev/naming.md):
+  references resolve by name first, follow splits and merges, and warn when the entity split,
+  merged or vanished, or was found by geometry only (operations that report no history yet).
+  New planar sketch attachments use exact box, extrusion cap/side and immutable imported-face
+  source certificates with checked target and author occurrence paths. A missing or changed
+  source fails explicitly; Redefine Sketch Plane previews reattachment or a fixed plane while
+  retaining current geometry and dimension identities. Unsupported modified faces need an
+  explicit fixed plane. Legacy attachments retain their original resolver behavior.
+- Modelled threads are cut as a faceted body (curved faces within 1/200 of the pitch); Extrude
+  and Revolve To Object on a curved face cut the tool back to the target's surface.
+- Explicit sketch breaks preserve exact ellipses, fit/control splines (including high degrees)
+  and conics; analytic trim/break also sees free-form cutters. Free-form curves cut at a tangent
+  touch (no clean crossing) enter that profile as polylines.
+  Sweeps along 3D sketch curves follow their polyline (smooth walls when the path is smooth).
+  A sweep with a twist, an end scale or a parallel or direction orientation (#771) follows its
+  path that way too, even along sketch lines and arcs: B-spline walls through stations, ruled
+  walls through denser stations where the path has corners or the profile has holes.
+  Guide rails (one or two, #771) do the same: each station meets every rail once, and the rail
+  turns the profile and scales it (or stretches it across to the rail) against the start; two
+  rails carry it between them. Rails along a path with sharp corners are refused for now.
+- Extend intersects exact ellipses and rational/high-degree splines without moving the line or
+  circular support. Associative free-form offsets have a whole-span 0.002 mm normal-distance
+  certificate and refine within bounded node limits while retaining existing IDs.
+  At the node limit, geometric certificate subdivisions accommodate unequal spline parameter
+  speeds without changing stored nodes or relaxing the distance tolerance (#971).
+  Associated offset fit nodes stay hidden from display, picking and snapping; dragging the
+  editable source updates the derived boundary live. Break Association restores point editing.
+  Singular, self-intersecting and ambiguous curves refuse atomically; mixed junctions and nonsmooth
+  closed natural-spline seams remain limitations. New explicitly closed fit splines and closed
+  offset outputs use periodic C2 interpolation, supporting repeated certified offsets; older
+  natural splines are preserved. Clicking the starting fit point deliberately closes a new loop.
+  Newly captured adaptive profile references with complete source coverage retain their outer
+  and hole identities through span-count changes, including parameter edits after extrusion.
+  Partial, intersected or ambiguous boundaries do not qualify for these whole-source references.
+  Legacy curve-span multisets remain exact and unchanged; already-lost selections may need
+  reselection. Format 12 stores the new bounded whole-boundary references.
+  Projected analytic boundaries follow nested loop identities through resizing, including
+  stationary holes and rounded corners. Supported convex, tangent line-and-arc boundaries
+  can lose or regain corner arcs during an inset while preserving reserved curve identities
+  and linked profile selections. Format 12 saves those associations; compatible older closed
+  offsets upgrade structurally without changing their curve IDs. Breaking an association
+  freezes its current boundary and materializes downstream profile references. Child offsets
+  of a boundary with retired arcs still require breaking its association first; mixed or
+  nonconvex junctions and retained references to disappearing individual arcs remain limited.
+- Extrude and Revolve editors retain original direction, extent expressions, explicit targets,
+  axes, From/To inputs and All-profile intent. No-op edits preserve downstream dimension names
+  and selected occurrence frames; cancel and successful edits preserve one-step undo history.
+  Placed feature edits preview through the edited timeline entry, and cylindrical Emboss guides
+  use the sketch's actual target, author or uniquely placed third-component frame.
+  Revolve rotators follow the actual signed axis and support symmetric and two-sided extents;
+  dragging a To Object extent converts its derived value to an explicit angle. Legacy reversed-axis
+  symmetric geometry is preserved through format 11's explicit legacy convention. New revolves
+  use the sketch-normal direction for each selected profile, including To Object and curved
+  target trimming, independently of the selected axis sign.
+- Cylindrical emboss/deboss wraps bounded orthogonal line profiles, including holes, concave
+  outlines and nested islands, onto complete exterior cylinders or coaxial sleeves with exact
+  radial walls. New features infer a unique eligible cylinder when the face field is empty;
+  ambiguous targets require an explicit face. Saved target
+  and author occurrence paths retain the chosen placements; missing/split faces refuse rather
+  than retarget. General free-form profiles, seams, stepped cylinders and other curved surfaces
+  remain unsupported. STEP round-trip and independent radial/volume checks cover this subset.
+- Shell and offset faces work on bodies of planes, cylinders, cones, spheres and tori (convex or not:
+  filleted boxes, bosses, domes, countersinks; corners where four or more planes meet, such as a
+  floor falling to a drain, as long as the corner's edges are all convex or all concave); draft on convex planar bodies and on walls (planes, cylinders → cones) between caps; lofts through three or more sections are smooth (B-spline sides through every section), two
+  sections ruled. Circular-meridian barrels retain curved inner walls through either axial
+  opening (#2421). Solid lofts preserve holes through sections with matching hole counts
+  (#2435), including inner walls and caps with openings; a hole cannot appear or disappear
+  between sections, and sections with holes cannot collapse to a point.
+
+- Sketch corner tools: fillet and all three chamfer modes pick a connected corner even when
+  its endpoint overlaps the fixed origin or a loose point. Ordinary drawing still snaps to
+  the origin; clicked UI regressions verify geometry, closed profiles and undo.
+- Sketch display: drawing, picking, highlighting, tool previews and profile shading share
+  adaptive projected curve boundaries. Fit, zoom, display scale and placed sketch frames
+  invalidate the display cache without changing CAD geometry or timeline history. Work
+  budgets and clipped paths prevent unbounded sampling or invented edges across the eye plane.
+  The Sketch Palette scrolls its options on short windows and enlarged displays while
+  keeping constraint status and Finish Sketch visible.
+- Face projection: closed boundaries have a deterministic outer-first order. Refresh matches
+  existing geometry before assigning positions, retaining saved curve IDs and constraints
+  across enumeration changes and resize, including concentric circles. Ambiguous identities
+  retain the last geometry and report a lost reference; permutation matching is bounded.
+- Project accepts complete supported preselection in one undo step. Visible external sketch
+  curves and points retain their source sketch identity; model geometry, axes and planes use
+  the existing linked projection commands. Rejection preserves the document and selection;
+  mixed selections retain ordinary tool-first picking.
+- Inline sketch dimensions: Tab and Shift+Tab cycle within the active shape's value boxes,
+  selecting visited values for replacement. Expression completion retains forward-Tab
+  priority; real keyboard regressions cover rectangles, lines and single-value circles.
+  Typed lengths, radii, line angles, signed arc sweeps and slot lengths persist as constraints
+  and expressions through save/reopen. Shape creation and its dimensions form one undo step;
+  rejected values keep the editable field focused.
+- Repeated components: Browser selection, visibility, properties, copy and Move/Copy use
+  checked occurrence paths. Active nested occurrences author planar sketches and solids in
+  their selected frame. Pending moves compose through parents; dialog cancellation restores
+  its selected move. Source materials and body/face appearances follow transformed instances.
+  Shared nested definitions remain shared. Deep Paste New copies reachable definition graphs,
+  independent feature/input histories, styles and internal motion records, with bounded geometry
+  checks and explicit external-link notices. Paste New selects the copy while preserving the active
+  authoring context. Imported periodic STEP seams survive placement and reexport with shared
+  topology and appearances intact. Recorded body transfers preserve historical Join/Cut membership,
+  material, placements and machining data through edits, copying, undo and reopen. New 3D wires
+  record their coordinate frame; legacy wires migrate from known provenance without changing
+  coordinates. Broken legacy links with missing provenance can require explicit refresh or relink.
+  See [occurrence workflows](docs/occurrence-workflows.md).
+- Toolbar drops on panel labels, gaps and margins append commands with insertion feedback;
+  button drops keep insert-before ordering.
+- Parameters and Configurations have distinct actions in the SOLID toolbar's CONFIGURE panel.
+  Parameters opens the user/model variable editor; Configurations opens the configuration table.
+  Configure remains available in the panel dropdown.
+- Parameter creation supports Enter with validation and continued keyboard entry. Shared
+  expression autocomplete supports Up/Down selection, Enter/Tab acceptance and Escape dismissal;
+  accepting a suggestion does not submit a parameter or trigger viewport shortcuts.
+- Movable window title bars follow the app's dark/light header palette. Radial right-click
+  menus are opt-in in Preferences > Navigation; ordinary context menus remain the default.
+- Desktop distribution: running Windows windows and executable resources use the app icon;
+  packaging validates icon resources. Nix installs launchers, MIME data and generated icons,
+  with explicit launch apps and Vulkan-loader/driver discovery. Flatpak feed instructions
+  register the required runtime source; release checks exercise desktop modelling on X11/Wayland.
+- OpenGL rendering clamps effective anti-aliasing to 1x across UI pipelines, textures and CAD
+  callbacks to prevent black frames. Other backends retain the requested sample count, and
+  stored preferences remain unchanged.
+- Configuration rules: ordered typed conditions can drive parameters and suppressions or
+  restrict values. Preview explains effective values without modifying the document; applying
+  rules validates rows atomically. Length expressions retain their authoring units across
+  document-unit changes. The UI supports structured All/Any/Not conditions and rule ordering.
+  Component styles and certified semantic face styles are available; unsupported lineage refuses
+  atomically, and stale certified face paint cannot jump to another surface. See [configurations](docs/configurations.md).
+- Sheet-metal material: inherited holes, crossing edge notches, overlapping cuts and retained
+  islands share the same boundaries in flat preview, DXF and unfolded solids. Detached material
+  pieces survive unfold/refold as one logical sheet group, including split flanged sheets.
+  Cut-outs made in the flat pattern cross bends at any angle or curved: their edges fold to
+  helices and curves on the bend, their walls square to the sheet. Free-form bases use bounded
+  sampling.
+  Parallel prismatic partial-depth cuts retain pocket side and depth through transfer and
+  unfold/refold, with separate pocket contours in preview and DXF. Planar Intersect preserves
+  exact holes and retained islands, including the union of multiple selected profiles, and
+  records complementary depth layers as pockets while retaining the stock gauge. Unsupported
+  tapered or bend-crossing machining refuses atomically instead of restoring material later.
+  Sketches attach to a sheet's flat faces (base and flanges, either side) by panel, in the
+  flat pattern's coordinates, and follow it through rebuilds and unfold/refold.
+  A flange on another flange's far edge (a return) follows that flange's closed end and keeps
+  clear of the flange beside it, and the returns of one feature are mitred toward each other
+  with the rule's gap where their flanges meet at a corner; returns of separate features, and
+  flanges on returns, are not closed toward each other.
+- Rolling-ball fillet accuracy: independent offset-cylinder tee references check surface
+  distance, actual trimmed tessellation, supporting-cylinder contacts and tangency at two
+  scales. The measured trimmed-part error is below 0.0001 mm; this is an analytic geometry
+  check. Under-resolved fits return an error.
+- Contact driving checks the trajectory between clear endpoints, including linked joints,
+  playback and sparse motion exports. Checks use bounded tessellation samples, not exact
+  continuous collision detection; local thin walls and small details remain limitations.
+  See [contact-set limits and recovery](docs/contact-sets.md).
+
+## Assembly dragging
+
+The design's first part is grounded when it is made, and a left-button drag repositions a free part (`occurrence.drag`: one undo step, exact occurrence paths including repeated jointed definitions, any floating-chain member carries the chain, grounded parts and joints hold where present, Escape cancels).
+
+## 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.
+

-//! 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. |
