The results start on the undeformed shape (scale 0) and the deformation
swings, eased, from 0 to x150, back and out again, one picture per frame.
The video ends on a 60-frame camera orbit round the deformed beam
instead of cuts between views. The results camera is drawn back so the
contour legend leaves the beam clear, and each stage holds 2-3 s.

A band under the window names the tool behind each stage (open, mesh,
batch, check_model, solve, show_results). caption.py draws the bars in the
standard library from the interface's Inter SemiBold (OFL): a minimal
TrueType glyf reader, a non-zero scanline rasteriser and a zlib PNG
writer, unit-tested with python3 -m unittest. ffmpeg pads each picture
and composites the bar with its overlay filter.

The setup's symbols (fieldcraft_render::glyphs) are built with the display
data and drawn over the model in every style, at the drawn nodes (a results
plot's deformed shape), muted over results; the clipping radius holds them.
Theme tokens give their colours in light and dark. The browser's Loads & BCs
and Interactions rows get eye toggles (ui.set show_loads, show_interactions),
also in the view menu. The GPU viewport draws reference point names with the
interface's font; the bottom left says which definitions are sampled.

glyphs::Glyphs picks where a model's setup symbols go (resolving its sets
once, thinning them on a grid, capping each definition and sampling large
ones with a note) and draws them into a Scene at the nodes' current
positions: cones for constrained translations (and rotations where nodes
rotate), arrows for forces, double-headed arrows for moments, arrows normal
to pressure faces, one arrow for gravity and body forces, a curved arrow for
centrifugal loads, crosses with names for reference points, lines for
couplings, hatched squares for rigid walls. Colours come from the caller by
role, muted over results.
Scene gains labels, drawn by the CPU rasterizer with a small bitmap font of
its own.

resolve_set_partial resolves the members of a set that are on the mesh, for
display: a set with a missing member still shows what it has, where
resolve_set refuses it. rotational_nodes is the check's rule for which nodes
have rotations (shell and beam nodes, not those of 2D sections), so the
viewport's symbols and the check agree.

A command run by a script, the control channel, MCP, the command search
or the browser left the ribbon on whatever tab it showed, so an agent's
session never showed the stage it was at. `catalogue::stage_tab` is the
rule, from the catalogue: a command's entry tab, none for the Tools tab
(files, history, the model summary). The app follows it after a command
that changed the model or the results display (queries leave the ribbon
alone); a script follows its last command with a stage. A ribbon click
runs a command of the tab shown, so it never moves the ribbon: a test
checks every entry and drop-down command against its tab.

The demo used the corpus I-beam, which is extruded along z and so stood
upright. A new corpus part, cantilever-i-beam, is the same section on the
YZ plane extruded along x, web upright: a sweep along a horizontal axis
for the meshers, and a cantilever that bends downward on screen. The
i-beam part is unchanged (its corpus row and the meshing tests keep it).
The demo clamps it at x = 0 and loads the free end with 1000 N in -z
through a kinematic coupling, and now checks the solution against beam
theory and stops when it is off: tip deflection (bending plus shear)
within 3 %, root bending stress (stress_xx along the top flange,
extrapolated to the root, nodes from the Abaqus deck) within 2 %.
docs/meshing/corpus.md regenerated with the new part.

A factor of 0 was refused, so a picture sequence swinging the deformation
out from the undeformed shape had to start at a small factor or switch
`show` off. 0 is now a factor like any other (the view stays deformed), and
the results panel no longer works around the refusal. The MCP show_results
docs say so, beside `deformed: false`.

`ui.view` and the MCP `screenshot` tool only turned to the named views, so
a picture sequence could only cut between them. `Orientation` (render) is a
camera orientation in degrees, {yaw, pitch, distance?}, checked as hostile
input: angles finite, distance finite and above 0, yaw wrapped, pitch
clamped to ±90, distance to 0.001–1e9. `modelcraft_engine::view::orientation`
parses it from JSON for both callers:
- control channel `ui.camera {yaw, pitch, distance?}` turns the app's camera;
- MCP `screenshot {camera}` turns it first (bridged through `ui.camera`,
headless in the CPU render, framed unless a distance is given). `view` and

Main's oracle job failed at 8cba3a7: scordelis-lo-roof-solid u_z moved from
-0.3014029226397275 (blessed before #50) beyond its 1e-9 band. The case is a
thin shell (R/t = 100) of one layer of hex20R solids, ill-conditioned, so
rounding alone moves u_z by about 1e-9 relative: on macOS #50's multithreaded
supernodal factorisation moved it by 8.2e-10 (to -0.3014029223929), #52's
interpolation order by a further 1.3e-10 (to -0.3014029223541), and Linux
CI by slightly more, past the band. #52 kept the lattice geometry the same.
The result itself is unchanged at the 1e-9 level (0.33% from the
reference).
A quantity may now set `fixture_relative` (with a required
`fixture_reason`) for a wider fixture band; Scordelis-Lo uses 1e-7 and is
re-blessed. Moved-fixture messages print full precision.

* mesh: one transfinite interpolation for mapped hex and mesh.block; stable oracle report
mesh.block's lattice is now built from the structured hex mesher's
transfinite code: faces by quad::transfinite_grid, the interior by the new
quad::transfinite_volume (Gordon-Thiel, blended by the block's graded
parameters), which hex::mapped now calls too. 2D patches are the
transfinite_grid of their sides. Edge curves return their corners exactly.
Oracle: a zero-reference quantity (rounding noise) keeps its absolute
tolerance as its fixture band, and docs/oracle.md shows such noise and
relative errors inside the fixture band as bounds, so the report no longer
changes with the order of floating-point operations (it failed the
'docs/oracle.md is current' check on main after #50). Scordelis-Lo moved by
1.4e-9 relative (an ill-conditioned thin shell of solids: sub-ulp node
changes) and is re-blessed.

* simplify: shared face filling and lattice index; faces blended like the volume; exact ends for every edge
quad::transfinite_faces fills a block's six faces (with a per-face hook
that hex::mapped uses to project onto its B-rep faces) and
quad::lattice_index fixes the lattice layout for all three users.
transfinite_grid_blended blends faces by the block's graded parameters, so
faces and interior use one parametrisation and mesh.block reproduces its
earlier Gordon-Hall lattice (the Scordelis-Lo fixture is back to its
blessed value). Straight edges also return their corners exactly.

* Structured hex meshing: multi-level extrude and revolve, one-to-one sweep, mapped blocks (M5)
modelcraft_mesh::hex::hex_mesh meshes a face-tagged boundary surface with
hexahedra by the first structured method that fits: a straight or
rotational multi-level sweep (imprinted cross-section arrangement, cuts at
reflex corners, mapped/annulus/free regions), a one-to-one sweep through
rings of linking faces (least-squares affine layers with residual
correction), or a mapped logical cube (trivariate transfinite
interpolation). Interval assignment couples shared curves; boundary quads
carry B-rep face tags; the certified validity gate, a tiling check and a
fidelity check guard the output; hex20 mid-edge nodes go onto the faces.
Shape::face_surfaces exposes the analytic face surfaces; the corpus runner
gets a structured hex column.

* mesh.hex.generate: structured hex meshing as a command
Meshes one body, every body of the open design or an imported surface,
replaces the mesh, tags element faces with the B-rep faces (so sets by
geometry resolve) and reports per body the method, counts and quality.
The quality pass certifies each element once and feeds the validity gate
(quality::validity_gate_checks). Shape::size gives the cached body size
for defaults instead of a full measure.

Smooth single-loop sections (cylinders, tori, vases) get a butterfly O-grid
instead of the free mesher; interval assignment raises counts by the

beyond the element limit is refused before any work and mapped limits are
no longer swallowed. The corpus reports hex8 and hex20 quality.

per node, flux shape functions live on the stack, and the arrangement's
exact side test and distances serve the region probe. The engine takes
the boundary options mesh.tet.generate takes and names unnamed faces by
index like it; the corpus hex20 run reuses the winning method; the
mapped entry lists mesh.hex.generate too; the octree icon is redrawn
under its new id.

The isotropic elasticity splits into D_dev + K m mᵀ; an element-wise

K_dev + K G M⁻¹ Gᵀ (Hughes §4.3–4.5). Q2–P1disc and P2–P0 are inf-sup
stable; Q1–P0 does not lock; tet4 and wedge6 still lock and are refused, as
are orthotropic materials (named at the section). ElementDofs counts the
condensed pressures. Verified: element patch, rigid modes and totals for

traffic lights, own caption buttons and resize zones elsewhere (titlebar.rs);
- workspaces (Prepare, Model, Analysis, Results) with their tabs, and panels of icon

- 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.

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

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.

A structured mesh of a six-sided block from its corners, with circular
and elliptical edges (Gordon-Hall transfinite interpolation), grading,
named faces, edges and vertices as geometry tags, and joining to the
existing mesh face to face (refused otherwise). solve.probe takes "at"
points and reports the nearest node with a result.

* Model, fem and decks: point masses, rotary inertia, springs, dashpots and rod3 trusses
Model: PointMass and Spring definitions (spring | dashpot; to ground or
two-point; along a degree of freedom, a vector or the line of the ends) on a
set or reference point, resolved per node; ElementKind::Rod3. fem: rod2/rod3
truss kernel on Basis::Line2/Line3 declaring ElementDofs (translations).
Decks: Abaqus T3D3, MASS, ROTARYI, SPRING1/2/A, DASHPOT1/2/A; Nastran CONM1,
CELAS2, CDAMP2; LS-DYNA ELEMENT_MASS/INERTIA and ELEMENT_DISCRETE; what a
format cannot take is reported. Commands model.mass.* and model.spring.*.

* Implicit solver: trusses, point masses, rotary inertia and springs on the DofLayout
Trusses declare their translations like solids; point masses, inertia and
springs ask the layout for the kinds they need at their nodes (translations,
rotations), and reference points they use get six degrees of freedom. The
matrix pattern takes rows for those points; dashpots are ignored with a
warning. Existing results are bit-identical (hash-checked).

* test: hostile-params test runs under small session work caps
Session gains Limits, the defaults of mesh.tet.generate's max_steiner and
max_tets (production values unchanged; a parameter still overrides them;
file.open keeps them). The registry-wide hostile-params test runs on
sessions with small caps, so the needle-triangle tessellation it meshes is
refused at once instead of meshing to the 50k Steiner cap: the engine test
binary drops from ~350 s to ~20 s locally.

* ci: move heavy tests to a heavy job on main, nightly and on demand
Four slow tests are #[ignore = "heavy: ..."] (every corpus recipe, the
cantilever convergence study, the explicit-vs-modal cantilever period, the
generic-predicate rational cross-check); fast representative tests of each
area stay in the PR gate. cargo xtask test --heavy runs every ignored test
(benchmarks included) and the doc tests; cargo xtask test and ci run the
rest without the doc tests. The new heavy CI job runs it on pushes to main,
nightly and on workflow_dispatch. Branch jobs restore main's rust cache and
no longer save their own. AGENTS.md documents the rule.

* test: the three slow LBM verification cases run in the heavy job
The Stokes-drag sphere array, the staircase-pipe convergence study and the
developing-channel case are heavy (21 s, 11 s, 6 s alone); plane
Poiseuille, Couette, Taylor-Green, reproducibility and the stability
limits stay in the PR gate.

- model: materials gain solver-neutral plastic (bilinear isotropic/kinematic,
hardening table, Johnson-Cook with adiabatic heating), damage (Johnson-Cook
D1-D5) and erosion (plastic strain); explicit steps gain nonlinear_geometry
(default on) and stress_rate (jaumann | green_naghdi).
- fem: rotation (Hughes-Winget, Flanagan-Taylor), plasticity (radial return,
capped bracketed Newton for Johnson-Cook, damage; the update takes the
mechanical strain increment so thermal strains can be subtracted), closed-form
hex8 gradients for deformed configurations.
- explicit: updated Lagrangian hex8/tet4, per-element material state, erosion
with reported energy, plastic work in the energy account.
- solver: warns that the linear solver uses the elastic constants of plastic
materials (results hash-identical).
- decks: Abaqus *PLASTIC (+ Johnson-Cook keywords), Nastran MATS1/TABLES1,
LS-DYNA *MAT_PLASTIC_KINEMATIC / *MAT_PIECEWISE_LINEAR_PLASTICITY; what a
format cannot express is reported as Unsupported.
- engine: model.material.plasticity, model.material.damage (catalogue ready),
explicit element probe, eroded elements in the solve summary.
Step commits before the rebase onto the DOF framework: branch explicit-x2-steps.

cargo xtask app-icon computes an isometric L bracket with a bolt hole and a
structured hexahedral mesh (O-grid around the hole), draws it with
vectorcraft-cli and writes icon.svg/png, small-size artwork, the iconset,
icns, ico, an Icon Composer ModelCraft.icon (floor grid Default/Dark, part,
mesh) and its actool Assets.car. The desktop app uses the 256 px export as
its window icon, falling back to eframe's default if it cannot be decoded.

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.
