The same check as the app's Help › Check for Updates and fieldcraft-cli update --check: the
latest release, whether it is newer, its page, whether it is signed and the asset this install
would download. It only reports. Checking reaches the network, so only the desktop app and the
CLI switch it on; tests, scratch sessions and the browser build refuse without asking.

Boundary condition, load and interaction symbols are wireframes (thin lines,
no shaded cones), so they never hide the mesh or a contour plot:
- a crossed wire triangle per constrained translation, tip on the node,
coming from outside the part where the set's faces say which side that is;
a held rotation adds a smaller triangle behind it (the double mark); fixed
shows all three axes, a symmetry plane only its normal;
- forces as open-headed arrows ending on the node, as long as four support
units at one place and 2.5 over a set, so loads and supports stay in
proportion (#78); moments as an axis line and a right-handed curved arrow
(#79); contact and tie surfaces as small squares on their faces;
- a constant size on screen at any zoom (#80): the symbol unit is the size
setting (View > Symbol size, `ui.set {symbol_size}`, 14 pt by default)
times the model length a pixel spans, rounded to a quarter of a doubling;
- spread evenly on a grid a few symbol units across, so their density follows
the screen, never more than 400 per definition;
- a layer of their own on the desktop (GPU and CPU): zooming rebuilds and
uploads the symbols only, never the mesh's scene; framing leaves them out;
- colour per kind from the theme's tokens (a new contact colour), and the
definition selected in the browser drawn in the selection colour, wider;
- depth-tested against the model with the line bias that keeps them on their
own surface; a load at a reference point or a single node and a reference
point's cross are drawn over the part (#78).
Headless pictures (MCP screenshot, `ui.render`) frame the camera first and
draw the symbols at the default size for it.

A sample may carry a SolidCraft script (the corpus recipe form) whose design
opens before its commands run, and its script sees the design's bodies.
fieldcraft-engine now builds fieldcraft-geometry with its scripts feature.
The start screen scrolls its sample list, and a test keeps the file.sample
form's choices in step with the samples.

Meshes the open design's bodies (or the listed ones) as the cells of one
conforming all-hex mesh with one size and tessellation tolerance for all;
elements carry their cell's body, boundary faces its B-rep faces. A cell
that is no block, or cells that touch without sharing whole faces, is an
error naming the bodies. Catalogue entry with its VectorCraft icon, the

Model: Newtonian fluid materials; fluid domains (box, spacing, conditions on
the box faces, obstacle bodies with conditions on their named faces, initial
velocity, body acceleration); fluid steps with caps. Deck writers refuse
fluid steps; a fluid-only model needs no mesh in model.check; one step
selector (Model::select_step) for every solver.
New L2 crate modelcraft-lbm: D3Q19 two-relaxation-time collision with Guo
forcing; halfway bounce-back walls (moving walls after Ladd), slip faces,
periodic pairs; Zou–He velocity and pressure faces with the D3Q19
transverse correction; obstacles voxelised from the face-tagged boundary
surface with exact predicates and symbolic perturbation; momentum-exchange
forces per box face and per B-rep face; unit conversion, automatic time step
and Mach/tau limits; bounded runs with frames and force histories.
Engine: model.fluid_domain.create/edit/delete, model.fluid_domain.boundary,
solve.fluid (obstacles from the open design or imported surfaces, lowerable
caps), solve.probe for fluid fields and wall force histories. Fluid Domain,
Inlet & Outlet and Lattice Boltzmann toolbar entries are ready.
Verification (analytic): plane Poiseuille exact with Λ = 3/16 and second
order (2.000) with Λ = 1/4; Couette exact with the wall shear; Taylor–Green
decay second order (2.01, 2.00); staircase pipe; Stokes drag of a sphere
array within 1.7% of Hasimoto at R = 6; Zou–He channel; mass conserved to
round-off; bit-for-bit reproducibility. Benchmark: Schäfer–Turek 2D-1.

* Draw the open design and imported surfaces in the viewport
DisplayMesh keeps node labels on every element primitive (for results),
gains add_surface (geometry faces and their boundaries, coincident points
welded) and displaced (elements moved by nodal offsets). Bodies are
tessellated at a thousandth of their size; meshed models show the geometry
as boundaries only.

* results.* commands: deformed shape, contours, mode shapes, animation, reaction sums
The results display is session state (ResultsView), set by commands that are
not edits. Nodal fields (displacement, von Mises, principal and component
stresses; principal stresses in closed form after Smith 1961) and reaction
force and moment sums per set. Results kept from an earlier revision stay
viewable, marked stale; solve.probe says when a result is stale. The Results
tab's display and reaction entries are ready.

* Results display: deformed shape, contours with legend, mode shapes and animation, probe, reaction sums
The viewport draws the session's results view: elements moved by their nodes'
displacements or a mode shape (automatic or given scale), faces split exactly
along contour band boundaries into flat-coloured pieces (same on GPU and CPU),
a legend with levels and extremes, a results panel whose controls run the
results.* commands, a click probing the nearest node (solve.probe), and stale
results marked. Solving from the form shows the result on the Results tab.
sample::cantilever is a solvable model for tests and demos.

* Simplify the results display (review)
One Contour in the plot; the results scene reuses scene::build; a solve shows
its result through the engine (ResultsView::for_result) and the UI raises the
Results tab when a view appears; the plot's scale and contour values are kept
across animation frames; design bodies are tessellated once per design; the
first content is framed where the display is rebuilt; field_values in one
match; probe reuses results::displacements.

* Results display for explicit steps: field frames, energy histories
The results view works on the engine's step results (static, frequency,
explicit): ResultsView.frame and results.frame {frame | time} pick an explicit
field frame; the deformed shape (true scale) and contours (element stresses
averaged to the nodes, velocity) follow it; animation runs through the frames.
The Results panel has a frame slider and plots the kinetic, internal, hourglass
and external energies with their values at the frame. sample::impact is a
steel bar flying onto a rigid wall.

Shape functions, Gauss and conical-product quadrature, stiffness, consistent and HRZ-lumped
mass, body forces, consistent pressure loads on faces, integration-point stresses and their
least-squares extrapolation to nodes, isotropic and orthotropic elasticity. The element table is
one row per kind, so wedges, shells and beams are added locally.

* modelcraft-solver: linear static and frequency analysis with an analytic verification suite
Assembly from the resolved model on the node graph, boundary conditions by elimination,
consistent pressure, gravity and body-force loads, nested-dissection ordering, sparse up-looking
Cholesky with a factor-size cap, reactions, integration-point and nodal-averaged stresses, von
Mises; shift-invert block Lanczos with full reorthogonalization for natural modes, participation
and effective mass. ADR 0001 records the own-linear-algebra decision (determinism, wasm).
Verified against closed forms: displacement and traction patch tests for every element, cantilever
tip deflection (Timoshenko) with convergence rates, Lamé cylinder, Kirsch hole (Kt -> 3),
cantilever and free-free beam frequencies with six rigid-body modes.

* Simplify the solver: shared face integration, block assembly, cached extrapolation
- model: one face integrator (nodal::face_normal_weights) for tractions and pressures
- fem: mid-side tables from ElementKind::edges, orthotropic via inverse3, symmetric
accumulation without a symmetrize pass, incompatible-mode recovery without K_uu, model's
coordinate check, dead table rows removed
- solver: one pattern search per node pair (block, scalar and diagonal adds), extrapolation built
once per element type, reactions from the prescribed rows only, matrices dropped after
restriction, the free-body shift keyed on the factorization error, step selection in the solver,
Error::Element naming the element
- engine: the solver owns the default step and the shift check; the model comparison runs once

* modelcraft-io: the .modelcraft file (modelcraft/1), atomic writes, autosave storage
A stored ZIP of a manifest (format tag, geometry sources with SHA-256,
part sizes and hashes), the model definition as stable pretty JSON, the
mesh and geometry tags in a compact binary part, and the journal one
command per line. Reading caps every size, checks every checksum and
replays the model through its checked methods. Model::without_mesh and
empty mesh fields left out of the model's JSON; geometry::read_file.

* engine: undo/redo on the journal, file.open/save/save_as, autosave and recovery
CommandSpec gains a kind: Model commands are journalled and become undo
steps; Session commands (file.*, edit.*) manage the session. Undo history
is bounded by steps and estimated memory. Geometry sources are recorded
with content hashes and reopened on file.open (missing or changed files
are warnings). Desktop app autosaves every 30 s and reports recoverable
models; Ctrl/Cmd+Z and Shift+Z/Y undo and redo.

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.
