* surface: weld at an absolute distance too; the engine welds CAD tessellations at twice SolidCraft's linear tolerance
Faces of a SolidCraft tessellation carry their own copies of shared boundary points, which agree
only to within the kernel's tolerance (up to ~2e-6 mm on the test corpus).

* surface: simplify after review
- The weld distance travels with the mesh (SurfaceMesh::weld_distance, set by Shape::tessellate),
so every consumer welds a tessellation correctly without opting in.
- Exact tests are infallible on predicates::orient2d_projected (shared with generic_orient2d), and
compute each vertex's plane side once per pair with an early reject.
- One Box3 for the weld, the BVH and shells; a Half struct for edges; the weld's two lookups share
one loop, with chained grid cells; cached normals for feature edges; shared parameter helpers.

* corpus: boundary surface preparation as a corpus stage
20 of 21 parts are valid boundaries with their expected genus; cross-cylinders' tessellation has
cracks and flipped triangles where its two intersection curves meet.

* render: display data from the FE model, orbit camera and CPU rasterizer
modelcraft-render (L1, no GPU): DisplayMesh (the unshared faces of solid
elements, shells, element edges, line elements, nodes), the orbit camera
and a CPU rasterizer with PNG output for headless snapshots, adapted from
SolidCraft's render crate. Workspace: egui/eframe/egui-wgpu 0.36 and
SolidCraft's patched egui-wgpu from the pinned rev.

modelcraft-ui-egui (L5): ModelApp over the engine Session; GPU viewport
(lit faces, element edges, nodes) with a CPU fallback; orbit/pan/zoom,
standard views and fit; model tree; commands panel generated from the
registry with a JSON parameter form; status bar; control request
handling (engine.*, ui.*, ui.screenshot, ui.render). apps/modelcraft:
eframe window, --sample, --control PORT loopback JSON-lines server.
Adapted from SolidCraft's ui-egui and app.

* render: simplify the display mesh (sorted face keys over maps, no unused fields)
Interior faces are found by sorting fixed-size face keys instead of a BTreeMap of Vecs, edges
are deduplicated by sort, and each element's corners are looked up once. Drops the unused
`element` fields on DisplayTri/DisplayLine, the unused Mat4::IDENTITY and corner_count, and
hoists the line colour out of the raster loop.

* viewport: split GPU geometry into batches within the buffer limit; refuse oversized CPU renders
A mesh with a few million boundary triangles made one vertex buffer larger than the device's
max_buffer_size (256 MiB under the limits eframe requests), and wgpu's default error handler
panicked. Geometry is now uploaded in batches of whole primitives, each at most 128 MiB and the
device limit, and all are drawn. A device error handler logs errors and shows them in the status
bar instead of panicking.
The CPU renderer refuses sizes over 8192 per side or 16 MP, and scenes over 20 million
primitives, with an error, and allocates its buffers fallibly. ui.render reports a size out of
range instead of clamping it; the CPU viewport fits a large window into the limit.

docs/formats/tagged-mesh.md defines the exchange: 3MF Core with an optional
ft:face attribute per triangle (and ft:faces per object) in a ModelCraft
namespace. modelcraft_geometry::tagged_mesh::read_3mf reads it from bytes
(wasm), capping every size and count and range-checking every index and
coordinate. geometry.import.mesh adds the surfaces to the session, which keeps
them beside the open design and restores them when a command fails.

* geometry: open .solidcraft designs, rebuild them and keep persistent face names
open_design(bytes) reads a design (container or JSON) with solidcraft-io, rebuilds its
timeline with solidcraft-doc and returns its bodies; each Shape carries SolidCraft's
persistent face names by B-rep face index, so a face keeps its name through a parameter
edit. sample::plate_design builds a parametric test plate in code.

* engine: geometry.open, geometry.bodies and geometry.tessellate
The session holds the open design (shared, restored on a failed command, journalled when
it changes). Hostile-params coverage includes non-files, missing files, oversized paths and
extreme tolerances against an open design.

* geometry: open_design_file reads through SolidCraft's bounded file access; simplify
The engine's hand-rolled capped read is replaced by open_design_file, which uses
solidcraft_io::vfs::read (refuses non-regular files before opening, works on the browser's
in-memory files). Drops the duplicate size check, simplifies the sample sketch and the
design-change test in Session::execute.

Survey of about 75 papers on robust predicates, Delaunay tetrahedralization, boundary
recovery, quality improvement and hexahedral meshing, with verified DOIs and the
licence of every associated code base. Architecture and roadmap now name the chosen
methods (robust CDT after Diazzi et al. 2023; octree-dual all-hex first). ADR 0001
adds the licence findings and the test-geometry rule.

A pure-Rust CAE modeling workspace following the SolidCraft conventions:
- modelcraft-model: nodes and elements by label with hostile-input validation
- modelcraft-geometry: SolidCraft's kernel (pinned git dependency) behind our own API;
tessellation into a face-tagged boundary surface for volume meshing
- modelcraft-engine: CommandSpec registry, Session::execute with rollback and panic guard,
scripts and a journal
- modelcraft-cli: list commands, run scripts
- xtask: layers (only geometry may use solidcraft-*), assets, licences, tests, wasm, ci
- AGENTS.md, architecture, ADR 0001 (libraries and licences), roadmap, CI
