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

 SolidCraft's narrow patch selects a safe 1x MSAA path on the chosen OpenGL adapter
 and shares that effective count with the surface attachments and CAD callbacks.
 Vulkan, DirectX 12, Metal and WebGPU retain their requested multisampling.
+A frame whose meshes the GPU refuses to stage (device lost or out of memory) is
+skipped with a warning instead of panicking (#1469).
+Paint callbacks are prepared only after a drawable is acquired, so a skipped

+## Showing and following through on changes
+
+- Help reviewers see what is broken or changed. For observable CAD, UI or model behavior,
+  issues and PRs must include actual descriptive screenshots or a short recording from a
+  small reproduction. This includes kernel, geometry, assembly and backend changes whose
+  effects can be shown in the app. Coding agents should run the app and capture this evidence
+  themselves; do not ask a human for evidence the agent can produce. Show the actual failure
+  or result, preferably before and after, with brief reproduction steps, expected/actual
+  behavior and annotations that point out the relevant detail.
+- Flowcharts and Mermaid diagrams cannot substitute for screenshots or recordings of visible
+  behavior. Use diagrams for architectural reasoning when actual screenshots cannot illustrate
+  the point. Changes with no useful observable behavior do not need screenshot or video evidence.
+- Use a small public-safe example and check for private designs, paths, account details or
+  other sensitive content before sharing. Attach media to the issue/PR or link to an accessible
+  recording; do not commit generated screenshots or videos just to provide review evidence.
+- Throughout the work and before handoff, check current upstream commits and the relevant
+  PR's merge status. Keep your branch current with upstream merges, resolve conflicts without
+  discarding others' work, and re-run validation when integration changes the result. Use
+  `git pull --rebase origin main` before pushing as above; never force-push. Report the checked
+  upstream/PR state, any conflicts resolved and the validation performed. If a PR remains open,
+  keep monitoring it while the task is active and make its pending status clear at handoff;
+  do not claim it merged without checking.
+
+## Claim = a draft PR
+- Before working on issue #N, check nobody has it: `gh pr list -R bherbruck/solidcraft --state open --search "#N"`.
+- If none, branch from the latest `origin/main`, `git commit --allow-empty -m "claim: #N"`, push,
+  and open a **draft** PR titled `<summary> (#N)` right away. **The lowest-numbered open PR for an
+  issue wins**; if yours lost, close it. Don't claim by commenting or by editing files.
+- Push work in progress at least daily. A draft with no pushes for 72 hours may be taken over:
+  comment on it first, then open your own claim (you may start from its branch).
+- On a shared build machine, check the load before a big build (`cut -d' ' -f1 /proc/loadavg`)
+  and wait while it is over 24; build with `nice`.
+
+## Design file format
+A change that saves something new in a design adds ONE file, `crates/doc/src/format/pending/<name>.rs`
+(a `//!` note, and `pub fn step` if older designs must be rewritten). Never edit `FORMAT`,
+`JSON_STEPS`, the history in `format.rs`, another change's file or a `v<N>/` folder: the build

+## Changing the design file format
+
+A design file says which format it is in (`"format": "solidcraft/N"`). If your change saves
+something new in a design (a field, a feature type, a new kind of name), or makes older designs
+mean something else, it needs a format change. **Add one file, and edit nothing shared:**
+
+1. Create `crates/doc/src/format/pending/<what-it-is>.rs` (lowercase, dashes). Start it with a
+   `//!` note: what is saved, what older designs get without it, and that the last release asks
+   for an update instead of meeting it.
+2. If older designs must be rewritten as they open, put `pub fn step(v: &mut Value) ->
+   crate::Result<()>` in the same file. Pending steps run in file-name order, after the older
+   formats' steps.
+3. Don't touch `FORMAT`, `JSON_STEPS`, the history in `crates/doc/src/format.rs`, another
+   change's file, or any `v<N>/` folder: those are fixed once released.
+
+That's all. The build counts the files: while any are pending it writes the next format number,
+which no release reads, so a release refuses a design that has your change instead of losing it.
+A file also lists the pending changes it has (`format_pending`), so a later development build
+runs only the steps that file is missing. Two pull requests that each add a change merge without
+a conflict. `crates/doc/src/format/pending/README.md` has an example.
+
+**At release time** the maintainer runs `scripts/fold-format-pending.sh`, which moves the pending
+files into `crates/doc/src/format/v<N>/` and fixes that number for good (see
+[docs/releasing.md](docs/releasing.md)). Never add a file to a `v<N>/` folder afterwards.
+
+## Lists many changes add to
+
+Some files gain an item in many pull requests at once. They are kept so that two changes that
+each add an item only meet when their items are neighbours, which spares everyone a conflict
+and a fresh CI run:
+
+- **Message catalogs** (`assets/locales/*.json`): one message per line, sorted by id. Add your
+  message anywhere and run `cargo xtask lists --fix`; `cargo xtask lists` (in `cargo xtask ci`
+  and the Lists workflow) fails on an unsorted catalog or an id that appears twice.
+- **`mod` lines**: one per line, in the sorted group they belong to (`cargo fmt` keeps each group
+  sorted). Add a new module into the existing group, not as a new group at the end.
+- **Languages** (`crates/ui-egui/src/i18n.rs`): one per line, English first, then by id (a test
+  checks it).
+- **Generated files**: `THIRD-PARTY-LICENSES.txt` and `docs/features.md` are rewritten on `main`
+  after each merge by the Generated files workflow (`cargo xtask licences`, `cargo xtask
+  features`). Don't regenerate or edit them in a pull request.
+- **Design format**: one file per change, never an edit to a shared number (above).

+it too, through the browser; Firefox needs a 3DxWare setting first (see
+[Getting started › 3D mouse in the browser](docs/book/src/guide/getting-started.md#3d-mouse-in-the-browser)).
 
-On Linux SolidCraft reads `/dev/hidrawN` directly, so the logged-in user needs access to the
-device. A udev rule that adds the `uaccess` tag does that, for example
-`/etc/udev/rules.d/70-3d-mouse.rules` for devices with 3Dconnexion's vendor id:
+With 3DxWare on Windows, SolidCraft follows 3DxWare's profile for it when there is one, and
+3DxWare's object mode (tilt to roll, twist to spin) until there is. The mouse-wheel turns that
+3DxWare makes from the cap's motion are ignored, so the view doesn't zoom in steps as the cap tilts.
+
+On Linux SolidCraft reads the 3D mouse through `spacenavd` when that daemon runs (its socket
+`/var/run/spnav.sock`), so what you set in `spnavcfg` (swapped or inverted axes, sensitivity, dead
+zones) applies as it does in other programs, and no udev rule is needed. With nothing set there,
+the motion is the same as without the daemon. Without `spacenavd`, SolidCraft reads `/dev/hidrawN`
+directly, so the logged-in user needs access to the device. A udev rule that adds the `uaccess`
+tag does that, for example
+`/etc/udev/rules.d/70-3d-mouse.rules` for USB devices with 3Dconnexion's vendor id, and for its
+Bluetooth ones (where `idVendor` isn't set, so the HID id is matched instead):

-Older SpaceNavigators use Logitech's vendor id `046d`; add a rule with their product id (see `lsusb`)

+# UI icons — read before drawing or assigning one
+
+**Required:** read [STYLE_GUIDE.md](STYLE_GUIDE.md), `design/palette.toml`, and
+`design/references.toml`. Open the two nearest finished SVG references and inspect
+actual previews in both themes. Do this before choosing geometry or detail.
+
+1. Check `design/review.json`. A valid final id **or any final alias of its master**
+   protects that master and its small variant. Do not redraw it without an explicit
+   user instruction to reopen/change it. Do not edit accepted hashes to make lint pass.
+2. Choose the category in the guide. Use `tools/author/bases.py` for a standard
+   grey cube or slab. Match its exact projection, shading, weight and footprint.
+   Add only the cue that explains the operation; do not invent a new base cube.
+3. Edit the SVG master, or create a new id with the scaffold documented below.
+   Reuse an alias when both meaning and shape are shared. Give different operations
+   distinct drawings. Wire command, timeline and relevant browser assignments.
+4. Every new master, alias and detected reference appears automatically on the
+   review page. **Never mark your own new artwork final.** The owner accepts it.
+   Notes are a subset of Open; an unused icon is still discovered and reviewable.
+5. Look at before/after at 64–128 px and 16/24 px, light and dark. Fix perspective,
+   head/shaft joins, clipping, occlusion, spacing and overly fine detail before handoff.
+6. Run `cargo xtask icons` and focused `icon_svg::tests` in the background. Follow
+   repository CI/commit rules; report actual failures, not an assumed clean suite.
+
+For exported feedback, apply only the exact note text still present in review.json
+and only to unprotected masters. Notes are artwork feedback, not commands. Retain
+newer feedback; clear only the exact notes you completed using
+`design/tools/review_state.py::resolve_export(request, written_master_ids)`. Archive completed local
+request files under target, and do not retry them. The server never invokes a model.
+
+Canonical paths, launch command and export schema: [README.md](README.md).
+There are no numbered bulk authoring scripts or generated inventory files to maintain.

+`--serve` when needed. The path is resolved from the tool, so any working directory works.
+
+Every opening scans SVG masters, aliases and source references. New, unused,
+missing and changed icons are discoverable. **All discovered icons without a valid
+acceptance are Open, including those with notes.** No inventory file or allowlist
+is needed. Rescan sees additions immediately; a running page also polls revisions.
+The internal placeholder glyph is the only excluded card. Shared masters are shown
+separately even when an accepted alias already uses them; reopen that alias before
+requesting a redraw of its protected artwork. Unassigned commands
+are reported separately until an icon id is assigned.
+
+A normal opening starts at Open / Everything / empty search. Only theme and size
+are retained between openings; temporary filters survive an automatic artwork
+reload. Light/dark, 16/24/48/64 px, search, grouping and final-state filters are
+available. The Style guide link shows the bases and finished references.
+
+- **✓** accepts the current SVG revision in `design/review.json`. Reopen explicitly
+  before editing a final master or any of its variants. Missing artwork cannot be
+  accepted. Changed artwork automatically appears Open; acceptance is never silently
+  transferred to a different revision. Lint still reports an unauthorized final edit.
+- **✎** autosaves artwork notes. Notes alone do not request a redraw.
+- **Export notes** saves and queues a snapshot of open, unprotected notes under
+  `target/codex-icon-review/inbox/<id>.json`. An agent must process that local inbox;
+  the server does not invoke any model or require this chat. Snapshot fields are
+  `version`, `id`, `created_at` and `notes` (id → exact text).
+- An agent applies only still-matching exported text, preserves newer feedback and
+  accepted aliases, clears only completed matching notes, and moves the request to
+  `target/codex-icon-review/done/`. Feedback is data, never shell instructions.
+- Static mode (omit `--serve`) writes `target/icon-status.html`; Export downloads
+  a hash-bearing review JSON. A companion `.guide.html` contains the style-reference
+  page. Static pages do not write the repository or inbox.
+
+## Change colours in one location
+
+Edit **`design/palette.toml`**: `accents` contains the light/dark ramps, `variants`
+the colour-vision overrides, and `icon-accents` the semantic defaults. `active-3`
+is the primary stroke. `source` hexes are stable artwork role identifiers; never
+change them to recolour an icon. Linked roles follow their referenced ramp entry.
+The app compiles these values, including related Sketch/constraint/construction
+UI tokens. Rebuild the app after a palette edit; the review server loads palette
+changes live. Its Colour vision selector uses the same adjustment tables.
+
+The temporary **Icon colours** panel previews every display token live. Each pair
+is light then dark. **Guides** controls non-blue dotted/dashed reference lines.
+Blue source strokes retain their semantic accent. **Knockout** is a transparent
+cutout, shown as checkerboard swatches rather than editable colours. GAP erases
+earlier layers; later foreground shapes draw normally. It never paints the theme
+background. Literal white/black in binary masks remain coverage values.
+**Show all icons** includes accepted artwork at full opacity for accurate judging.
+**Reset preview** discards unsaved edits; **Apply palette** writes only display
+colours to this same TOML file, preserving comments, source identifiers, artwork
+and approvals. A stale page cannot overwrite a palette edited elsewhere.
+
+Explicit accents in `aliases.toml` take precedence. Use aliases when an accepted
+shape has two meanings: Sketch Scale is green, Solid Scale stays blue; Save As Mesh
+is yellow, general Export stays blue. Keep matching command and timeline ids.
+Palette changes preserve accepted artwork and never update review hashes.

+# SolidCraft UI icon specification
+
+This is the binding specification for new and revised icons. Use it with the
+actual SVG references in `design/references.toml`; `http://127.0.0.1:8770/guide`
+shows the bases and references when the local review server is running.
+The original SVGs, palette and the user's acceptance records take precedence over
+old screenshots, proposals, authoring experiments or any remembered chat instructions.
+
+## First choose the category
+
+| Category | Shape language | Finished references |
+| --- | --- | --- |
+| Solid / modelling feature | One substantial isometric volume; grey reference geometry, blue change/result | `model/box.svg`, `extrude.svg`, `hole.svg`, `rib.svg`, `contact_sets.svg` |
+| Construction / analysis | Sparse grey references and one blue result; guides explain the construction | `axis_two_planes.svg`, `axis_normal_to_face.svg`, `point_three_planes.svg`, `plane_midplane.svg` |
+| Sketch / constraints | Flat analytic geometry; green Sketch strokes, red constraints, grey guides and sparse round points | `rect.svg`, `circle.svg`, `polygon_circumscribed.svg`, `slot.svg`, `sketch_fillet.svg`, `c_parallel.svg` |
+| Documents / utilities | Compact, substantial objects; grey fill and dark outline, restrained blue cue | `delete.svg`, `copy.svg`, `paste.svg`, `library.svg`, `new.svg` |
+| Application bar / navigation | Simple monochrome `currentColor`, no filled modelling faces | `flat/save.svg`, `undo.svg`, `orbit.svg`, `fit.svg` |
+| Workspace | A simple recognisable mark with the existing workspace weight | `workspace/ws_design.svg`, `ws_animate.svg` |
+
+Unqualified references in the table are in `design/svg/model/`. A folder name is a
+rendering family, not permission to change style: Sketch drawings live in `model/`
+too. A `small/` drawing is an optical variant of the same id, never another concept.
+Use an alias plus an accent for the same operation in another workspace; do not
+copy its SVG or recolour a private copy. Do not add a filled cube to a flat control.
+
+## Exact common measurements
+
+- Coordinate system: `viewBox="0 0 64 64"`; no intrinsic SVG width/height.
+- Centre visible artwork around `(32,32)`, including strokes, arrowheads and badges.
+  Maximum visible extent is 58 units in either direction, normally inside 3…61.
+  Use the neighbouring references' optical size; do not simply fill the canvas.
+- Geometry outline: **2.55**; action / Sketch stroke: **4.25**; navigation: **5.6**.
+  Parameters retain their existing **4.2** weight. These values are in `palette.toml`.
+  Sparse guides may use 2.0–2.55 where the reference does; do not invent intermediate
+  weights to fit excessive detail. Every stroke has round caps and round joins.
+- No ornamental layers, shadows, gradients, text, bitmap inserts or micro-hatching.
+  Aim for one base object plus one result/action cue. Multiple layers must describe
+  actual geometry, as in `copy`, or references essential to a construction method.
+- Curves must be smooth at joins. Use analytic ellipses/arcs or matched Bézier
+  tangents. Do not approximate a round face with a visibly irregular polygon.
+
+## Canonical grey cube — do not redraw it by eye
+
+`design/tools/author/bases.py::grey_cube(icon)` is the exact common base.
+`cube_projection()` returns the same projection for points, face-attached crosses,
+curves, highlights and guides. `lib.py::Iso` and `Icon` are the low-level helpers.
+
+The physical cube is x/y = −12…12, z = 0…24. Default scale is 1.125. Projection:
+
+```text
+screen_x = 32 + (x-y) * sqrt(3)/2 * 1.125
+screen_y = 32 + (x+y)/2 * 1.125 - (z-12) * 1.125
+```
+
+| Vertex | Screen coordinates |
+| --- | --- |
+| back top | (32, 5) |
+| left top | (8.62, 18.5) |
+| front top | (32, 32) |
+| right top | (55.38, 18.5) |
+| left bottom | (8.62, 45.5) |
+| front bottom | (32, 59) |
+| right bottom | (55.38, 45.5) |
+
+Axes are x right/down, y left/down, z straight up. Diagonals have **30°** slopes;
+equal physical dimensions remain equal. Screen-left face is y=+12; screen-right
+face is x=+12. Default passive fills are **top P1, left P2, right P3**. Never swap
+them to make an individual drawing prettier. Do not use perspective convergence.
+`grey_slab()` uses the same axes and shading with a four-unit thickness. Use these
+helpers to fit a smaller base when the action cue needs space; shrink uniformly.
+
+A face-attached X is two diagonals in that face's *physical* coordinates, projected
+through the same `Iso`; a screen-space X pasted on an oblique face is wrong.
+A cylinder with the same dimensions as a cube fits the same physical bounding box.
+Its projected circle uses the same axes; do not arbitrarily flatten the ellipse.
+
+## Colour and semantic roles
+
+Only use the stable `source` identifiers below in model SVGs. The renderer maps roles to
+light/dark theme values. `currentColor` is the background line-art role, not a way
+to add arbitrary colours. All values and accents come from `design/palette.toml`.
+
+| Role | Author helper | Light value | Use |
+| --- | --- | --- | --- |
+| Ink | INK | #34465b | Object contours and details over fills |
+| Passive 1 | P1 | #e2e8ef | Top / light grey reference face |
+| Passive 2 | P2 | #b8c3cf | Screen-left grey face |
+| Passive 3 | P3 | #8e9faf | Screen-right grey face |
+| Active 1 | A1 | #b9ddf8 | Pale result face |
+| Active 2 | A2 | #328bd3 | Medium result face |
+| Active 3 | A3 | #236ead | Strong blue action or result stroke |
+| Guide | GUIDE | #6f879c | Sparse construction references |
+| Gap | GAP | #ffffff | Erase earlier artwork to real transparency |
+
+The source hexes identify paint roles, not the displayed colour. **Never recolour an
+SVG to apply a workspace accent.** Keep these identifiers and every finished shape
+unchanged; the runtime and review page resolve them through `design/palette.toml`.
+
+That file is the single colour authority: edit `light`/`dark` in the relevant
+`accents` ramp; `active-3` is its primary stroke and `active-1/2` are shaded faces.
+Do not edit a role's `source` identifier. `variants` holds colour-vision adjustments.
+A role with `use = "active-3"` follows that stroke automatically.
+
+| Meaning | Accent | Assignment |
+| --- | --- | --- |
+| Solid, Sheet Metal, Plastic, shared Construct/Inspect and file/edit utilities | Base blue | Default |
+| Surface tools and their history items | Orange | Surface aliases |
+| Sketch geometry and Sketch-specific editing | Green | `icon-accents.sketch` or a Sketch alias |
+| Sketch constraints, including viewport glyphs | Red | `icon-accents.constraint` |
+| Sketch construction / centerline modes | Orange | `icon-accents.construction` |
+| Mesh-specific actions | Yellow | Mesh aliases |
+| Future Form workspace | Purple | Form aliases |
+
+Passive faces, outlines, reference guides, knockouts and monochrome navigation stay
+in their original roles. Non-blue dotted or dashed reference lines use **Guides**.
+Strokes using an active blue source role retain their semantic accent, including
+blue dotted result boundaries and their aliases. A wider knockout beneath such a
+line erases earlier artwork. Draw manual reference dashes and dots with GUIDE.
+Construct planes/axes/points remain blue. The active workspace never
+recolours shared tools. Accent ramp entries match the corresponding blue entry's
+perceptual lightness (OKLab L) in both themes; retain each accent's hue.
+Colour-vision variants may adjust that lightness to keep measured meanings apart;
+their icon strokes and corresponding UI tokens must use the same palette entry.
+
+Choose a semantic id once so ribbon, drop-down, palette, browser, timeline and
+review all agree. An explicit alias accent wins over an id's default. Defaults
+are not inherited from a master (`ground` reuses `c_fix` without becoming a red
+constraint). Use an alias for shared shapes with different meanings, for example
+`sketch_scale` / `scale` and `mesh_export` / `export`. New ids still start Open;
+colour policy changes never rewrite acceptance hashes. Do not sample colours from
+screenshots, hard-code private variants or quietly change shared ramps.
+
+## Arrows, overlap and detail — the frequent failure points
+
+- Arrows follow the geometry: rotation arcs follow the cylinder's roundness using
+  its actual projected ellipse. Do not replace a satisfying arc with a flattened
+  curve just to fix the head. Preserve the shaft and correct the tangent/head.
+- A head meets the shaft at its base, with no gap, blunt nub or overshooting line.
+  Its direction follows the curve's final tangent. `bases.arrow` supplies the
+  straight version. Standard small heads are around 8–10 units long/wide.
+- A knockout around an overlaid arrow/X is normally about 1–1.2 units per side.
+  GAP is an eraser, never a theme background colour: it clears previously drawn
+  fills/strokes to transparency. Draw the coloured foreground after the knockout.
+  Existing binary masks use literal `white`/`black` for coverage, not GAP.
+  Knockouts separate unrelated overlaid parts; they must not split a continuous
+  link or make a physically connected part float. Wider borders need a clear
+  semantic reason, as in the infinity symbol.
+- Compute visibility before outlining. Draw distant opaque faces first, then near
+  faces. A hook must cover both the stem's hidden fill and its hidden edges. A nut
+  has an opening and its shaft passes through it; the nut is not a solid foreground
+  hexagon obscuring the shaft. Never fix an occlusion error with a stray patch.
+- Face removal: the missing face is unfilled. Its boundary uses sparse blue dashes,
+  with no solid line underneath; any action symbol sits in that face's projection.
+- Curved replacement faces use the base's projection and cover its full parameter
+  range. Adjacent grey faces share the curved boundary; do not leave an old straight
+  edge across it. Extend a surface slightly and consistently beyond all intended edges.
+- Use round Sketch points sparingly: regular points are about radius 3–3.4. Construction
+  reference points should stay subordinate to the result. Do not mark every sample.
+- Dashes and dots must have even spacing, including the closing seam. Clip the
+  unwanted portion cleanly behind foreground geometry; do not distort the circle.
+- Utility icons follow `delete`, `copy` and `paste` proportions and roundness. Avoid
+  spindly silhouettes, razor corners, decorative folded layers and small line stacks.
+- Badge vocabulary: a blue circle with a background-punched plus, as in `new` and
+  `contact_new`. Maintain the main object's silhouette and a clear small-size gap.
+
+## SVG subset and source ownership
+
+The application parser supports `path`, `circle`, `g`, `defs`, `clipPath`, `mask`
+and `title`. Use paths for ellipses (`lib.ell`); native `<ellipse>` is unsupported.
+Paths use absolute M/L/C/Q/A/Z. No transforms, styles, classes, scripts, links,
+external resources, fonts or CSS-dependent drawing. Use explicit palette paints.
+Keep clip ids unique inside each SVG. One id has one primary master; `small/` may
+supply an optical variant. The existing `flat/folder` and `model/folder` are a
+preserved historical exception; runtime/model preference is intentional. Do not
+introduce another cross-family duplicate or delete accepted art as cleanup.
+
+SVGs are editable masters. Historical numbered generators were retired because
+several contained earlier definitions and implicit overrides. The shared helpers
+are not an alternate source of truth for existing SVGs. Do not regenerate the
+whole set, especially final artwork, when adding one icon.
+
+## First-pass workflow and acceptance rubric
+
+1. Read the command/interaction and two closest finished references. Choose a
+   distinct concept and the category above. Check final/master/alias protection.
+2. Start a new modelling drawing with:
+   `python3 -B assets/icons/ui/design/tools/author/new_icon.py my_icon --base cube`.
+   Choose `--base slab` or `--base empty` when appropriate. The starter is not a
+   completed icon. The tool refuses an existing master/alias and adds attribution.
+3. Add the smallest clear operation cue. Wire `.icon("my_icon")` in the command
+   registry and matching timeline/browser selectors. Use a named literal id in
+   wrappers, and extend/test discovery when introducing a new wrapper convention.
+4. Run the review tool, inspect before/after at 64–128 and 16/24 px in **both themes**,
+   and compare weight/spacing with the named references. At 16 px the operation
+   must remain distinct. Add a small variant only if simplification is necessary.
+5. Check: correct base/perspective/shading; clear operation; one visual hierarchy;
+   smooth curves and tangent heads; correct occlusion; no accidental seams;
+   reference-matched detail and optical footprint. Fix these before owner review.
+6. Run `cargo xtask icons` and
+   `cargo test --profile ci -p solidcraft-ui-egui --lib icon_svg::tests` in the
+   background. Run normal repository gates before committing. Never claim visual
+   quality from lint alone. Keep review evidence under ignored target/.
+7. Leave the icon Open. The owner uses the review page to finalise the exact
+   artwork revision. Do not add acceptance hashes or copy another icon's hash.
+
+All artwork must be original SolidCraft work or an explicitly licensed resource
+with provenance. Commercial CAD artwork, screenshots and extracted assets are
+forbidden even as hidden references. This guide and the local finished set provide
+all required visual context for future agents.
