Load. It has a Start-card thumbnail and a gallery capture; a test checks its tip deflection

Delaunay refinement split a boundary face edge at its midpoint even when that
midpoint lay inside the diametral sphere of a feature edge beside it. Each such
split halves the face vertices' distance to the curve, so they piled up against
it (the heated bracket grew face vertices 0.016 mm from a 4 mm-sized edge), the
improvement schedule could not lift the tetrahedra there to its target, and
inserted vertex after vertex around them: 29257 elements and about two minutes
to open instead of 23641 and 6 s. The SolidCraft pin move (4c91f9b) added one
interior vertex to the bracket's end faces, which changed the CDT enough to
expose it.
Following Shewchuk (1998), an encroaching midpoint now splits the encroached
feature edge instead.

crank-arm (and crank-mirror, kept as the same model under the name of
its mirror workflow) now cut the crank on its symmetry plane and the
half into seven cells: across the arm at x = 30, 60, 110 and 148, and on
two diagonals radial to the pocket's corner fillets. Every cell's
cross-section maps (four-sided blocks, the half O-grids round the bores,
triangle primitives at the pocket's corners); exact edge seeds give each
cut the same divisions on both sides, so mesh.cells merges all six cuts
and mesh.mirror reflects the half: 7 710 hex20, scaled Jacobian min 0.37
(was 0.17, and 0.009 for the swept mirrored half), edge ratio at most
7.0. Root σxx ±62.43 MPa against M/Z 62.6 MPa, the spindle carries the
1500 N. The test asserts the quality floor. Gallery images regenerated.

`quality::conformity` checks a solid mesh for cracks: the free faces must
close up (every corner edge on exactly two), no two distinct nodes may
coincide, and every element edge has one mid-side node. The hex tests
assert it for every method, hex20 included, and the crank arm sample's
7274 hex20 is conforming (#260: the disjoint lines are a display issue).

file.sample crank-mirror partitions the crank arm on its symmetry plane, sweeps
one half all-hex (hex20) and mirrors it into one conforming mesh, then defines
the crank-arm model. Samples may now run preparing commands (datums,
partitions) before their script sees the bodies. Its test checks the halves
alike and joined, every element valid and the sets on both halves; the heavy
test solves it: sigma_xx at the root -62.43 / +62.43 MPa against M/Z = 62.5.

The heavy test asked the upright's top to grow within 2 % of free thermal
expansion; the clamped bore holds it back by 2.1 % on the Linux CI's tet mesh,
which differs from macOS's (#115). 3 % still catches a wrong expansion
coefficient or temperature.

(crates/engine/samples/crank-arm.json), swept along z by mesh.hex.generate
as 7274 hex20 elements of 3 mm (scaled Jacobian min 0.17). The hex variant
drops the pocket floor fillet and boss chamfers, and its root arcs meet the
bosses 20 degrees off tangent so the arm's top face has no zero-angle cusp.
The square bore is fixed and 1500 N acts on the pedal hole; the faces are
picked by their surfaces, not their names. Its heavy test matches the root
bending stress to M/Z = 62.6 MPa within 3 % (0.3 % in practice).

Open (models, SolidCraft designs and tagged meshes in one picker), Save, Save As, Write
Deck and Recover go through the host's file pickers (rfd in the desktop app, injected as
Services so the UI crate stays portable and tests answer them). Files open on a copy of the
session in a worker thread and replace it only on success; files dropped on the window or
named on the command line open the same way. A recent-files list, an unsaved-changes prompt,
Cmd/Ctrl+O/S/Shift+S. Programmatic calls never open a picker: ui.start opens the form.

theme, help), the model's document tab and the version; integrated under the macOS
traffic lights, own caption buttons and resize zones elsewhere (titlebar.rs);
- workspaces (Prepare, Model, Analysis, Results) with their tabs, and panels of icon
buttons whose labelled drop-downs list the whole catalogue, coming-soon entries greyed
with their milestone; panels collapse, then go into a » menu, when narrow;
- the browser: geometry and mesh with eye toggles, definitions with counts, results;
- no permanent Commands list: command search (S, Cmd/Ctrl+K) and a command line;
- the context panel on the right only with context: the command form, results controls,
the selected definition's properties with Edit and Delete;
- navigation bar and orientation gizmo in the viewport; the journal timeline at the bottom
with undo positions;
- SolidCraft's light and dark tokens; craft-ui (IconButton, Tab, WidgetPalette).
Menus and the search are view state (ui.set {menu, palette}), so captures show them.

* Simplify: cached per-frame data, one command per timeline roll, workspace setters
- Icon textures are kept per pixel size (the shell draws several sizes a frame; the cache
used to clear on every size change and rasterise again).
- Opening a model or recovering one starts from an empty session instead of copying the
current one; the replaced session is freed off the window thread.
- Element counts, timeline items, search results and the selected definition's properties
are cached until what they show changes; timeline tooltips are built on hover; long lists
in properties are summarised.
- edit.undo and edit.redo take a count: a timeline click is one command.
- solve.run dispatches on the step's procedure (no string round trip) and reports its name.
- The workspace and tab change together through UiState::select_tab/select_workspace
(ui.set {workspace} alone now sticks); no per-frame syncing.
- One busy guard, Kind::verbs, a fit flag for background jobs, ModelApp::home_view, the title
bar's actions as an enum, dead code removed.

* Caps labels in Inter SemiBold
egui has no bold weight of its default font, so the ribbon's tabs and panel labels, the
workspace switcher and its menu, menu headings, the browser header, the context panel's
headers and the Solve label were thin, especially in the light theme. They now use a label
font family: Inter SemiBold 4.1 (SIL OFL 1.1, unmodified, fonts/OFL.txt, ATTRIBUTION.md),
with egui's fonts as fallback, installed with the theme on the live and offscreen contexts.
theme::label_font falls back to the default font until the family is bound (fonts take
effect from the next pass), so nothing can panic. Panels widen to their label's longest word.

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

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.

* 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.

Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm
* 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.

* 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.
