* feat(geom): surfaces through curve networks, and spline spaces to build them Adds spline_space (clamped B-spline spaces, Hermite interpolation, exact embedding by Bézier degree elevation and knot insertion, a monotone cubic for reparameterising) and network (loft, Coons and Gordon surfaces through curves in one or two directions, with G1/G2 cross-boundary conditions against a neighbouring face). Part of #763. Co-Authored-By: Claude Opus 5.5 <[email protected]> * feat(kernel): boundary surfaces from sketch curves, 3D curves and edges kernel::boundary_network turns sketch chains, 3D sketch polylines and edge chains into network curves, gives G1 frames of the faces along open edges (EdgeFaces), builds the B-spline face (sides split at chain vertices so a join shares the body's edges) and joins it into a surface body by stitching. G2 is refused for now (not supported yet). Part of #763. Co-Authored-By: Claude Opus 5.5 <[email protected]> * fix(kernel): second derivatives of B-spline surfaces in the vendored truck-geometry BSplineSurface::uuder and vvder multiplied the second differences by p instead of p·(p − 1), as BSplineCurve::der2 does, so every surface of degree p ≥ 3 (NURBS too, through its homogeneous surface) reported 1/(p − 1) of its second derivative: a cubic surface's curvature read as half. This is why a G2 boundary surface on a cylinder measured half the curvature it carries (#763). New tests hold both to finite differences for degrees 2 to 5. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01LGeCa5jWWdroMWvXxN3LLM * feat(kernel): G2 boundary surfaces against a body's face The network always carried the face's curvature across a G2 edge; the refusal came from measuring it with truck's halved surface second derivatives (fixed in the previous commit). EdgeFaces now reads the face's second fundamental form from the exact second derivatives instead of differencing the normal. A new test holds the curvature across a cylinder's edge to the cylinder's within 0.1%, also with a sheared far curve; G3 is refused (a network holds up to G2).

From such a corner the reference mesher's boundary walk ran onto the B-spline's extrapolation past its domain (a planar spline passes through every point of its plane there), and the face measured 289 mm² for its 158.5 (#763). The vendored mesher's bounded projection (nearest_projection, #2043) keeps the walk on the domain; this holds it there, by the faces, the measuring mesh and the display mesh. The display path (#1653) was never affected. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01LGeCa5jWWdroMWvXxN3LLM * feat(geom,kernel): three-sided boundary surfaces (one side collapsed to a point) A network curve may be a PointCurve: the apex where the two sides beside it meet. The curves through it cross it at the point itself, its row of the net collapses there, and the kernel's face leaves that side out of its loop (three edges, one vertex at the apex). One point per patch, as a side; refused elsewhere, when it moves, or with a continuity condition. Tests: a triangle and a quarter disc filled flat with their analytic areas (40 mm², 25π), by geom and by the kernel's faces and meshes. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01LGeCa5jWWdroMWvXxN3LLM * feat(doc): boundary surfaces through curve networks and loops of three or four FeatureKind::SurfaceNetwork saves a network as `u` and `v` curves, each a sketch chain (planar or 3D), a chain of a body's edges with an optional G1/G2 continuity, or a point (the apex of a three-sided patch), and an `operation` that can join the surface into the body of its edges. A SurfaceBoundary of three or four sketch curves, refused until now, builds as the flat Coons patch of its loop (three collapse the side opposite the first curve). The format change is one pending file; feature-walk goldens record the new variant's sketches, bodies and points. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01LGeCa5jWWdroMWvXxN3LLM * feat(engine): surface.boundary through loops of three or four and curve networks The command keeps its loop form (two to four curves of one sketch; three and four now build the flat patch of the loop, crown refused there) and gains a network form: `u` and `v`, each curve a sketch curve id, a {sketch?, curves} chain (planar or 3D), a {body, edges, continuity?} edge chain (g1/g2 with the face beside it) or a {point} for a three-sided patch, with `operation` new or join. Edits may move between the two forms (timeline.redefine accepts the command now that it has a dialog). Tests: analytic areas of loop patches and of a hyperbolic paraboloid bounded by four 3D lines (every mesh vertex on z = xy/10), a loft across two sketches, G1 and G2 measured across a cylinder's edge with inspect.continuity (angle < 0.1°; curvature jump 1e-16 with G2 against 0.027 with G1), 26 hostile networks refused without panicking, and u/v added to hostile_params_never_panic. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01LGeCa5jWWdroMWvXxN3LLM * feat(ui): Boundary Surface dialog Curves and Cross curves take sketch curves and edges (picks that meet end to end in one sketch or body are one chain); Continuity and Operation (New Body or Join). Two to four sketch curves of one sketch with nothing across are the loop patch; anything else is a network. Edit Feature brings either back (per-side orders, crown and stations the dialog does not show are kept). Strings in en, ja and zh.

Recipes gain boundary_surface, thicken and remove. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01LGeCa5jWWdroMWvXxN3LLM * refactor: boundary surfaces, review cleanups Project onto the face once per derivative evaluation (the frame is passed to natural() and reused by scale()), keep each track's finite-difference step instead of rescanning its table, export the kernel's edge-pick and chain caps and the default station count for the engine, doc and dialog to share, map TooLarge spline errors to KernelError::TooLarge, reuse the engine's operation parser, and skip the dialog's sketch lookup when the picks are no loop.

Editing and regeneration
UI artwork identifies the drawing masters and their consumers. Read the mandatory UI style guide before editing an icon. Edit SVG geometry and its command/UI assignments together; inspect both themes and small sizes. Temporary media and generated reports belong in ignored target/. Palettes and model presets are also editable Rust data.
The current macOS master is icons/app/macos/source/SolidCraft.icon/, including
its linked SVG layers and appearance settings. The earlier VectorCraft document
is preserved in the archive. No other native design projects were available for
the current UI set or preview card. Keep any future .vectorcraft, .ai or other
native work and linked inputs under that resource's source/work/, with an
attribution row; retain the editable document alongside its exports.
Regenerate all exports of the shared Windows/Linux/FreeBSD mark together:
cargo xtask app-icons
For macOS, use Xcode with Icon Composer support:
mkdir -p target/resources/macos-icon
xcrun actool assets/icons/app/macos/source/SolidCraft.icon \
--compile target/resources/macos-icon --platform macosx \
--minimum-deployment-target 11.0 --app-icon SolidCraft \
--output-partial-info-plist target/resources/macos-icon/icon-info.plist \
--output-format human-readable-text
cp target/resources/macos-icon/Assets.car assets/icons/app/macos/exports/Assets.car
cp target/resources/macos-icon/SolidCraft.icns assets/icons/app/macos/exports/icon.icns
Review and commit source changes and required exports together. Temporary renders,
tool caches and package staging belong under ignored target/ or dist/.
Normal builds use the committed exports and require no design applications.
The CLI still supports arbitrary PNG/ICO exports with solidcraft-cli icon.

Code and provenance
Resources remain compiled by their owning layer through existing APIs:
ui-egui::icons::paint and Tokens at L5, model presets in L2 doc, and sketch
fonts at L1. State, projection, interaction, commands and GPU bindings stay in
their current modules. Embedded data uses CARGO_MANIFEST_DIR; application code
needs no runtime resource registry or repository lookup.
cargo xtask assets requires an exact attribution row for every collected file
except Markdown documentation, and continues checking file assets elsewhere in
the repository. This includes native work, Rust masters, catalogs, shaders and
platform templates. Packaging selects explicit current files and fails when
required inputs are absent. Archived artwork has no production consumers.
Dependency-owned egui fonts and vendored renderer shaders stay with their
libraries; their licences remain in THIRD-PARTY-LICENSES.txt and ATTRIBUTION.md.
System fonts, optional packs, user fonts/canvases/decals/materials and native OS
controls retain external ownership. Root licence/notice texts stay canonical.
