The desktop's ModelApp in a web page through eframe's web runner
(WebGPU, WebGL2 fallback, `?webgl` to force it), built with Trunk.
The browser services sit behind the UI's host-service seams: File >
Open uses the browser's file picker, dropped files are read
asynchronously, and both go into the page's files; Save, Save As and
Write Deck hand the written file out as a download. Autosaves go to the
recovery folder as on the desktop and are mirrored to local storage, so
File > Recover offers what a closed or crashed page left. `?sample=NAME`
opens a sample. A loading screen with the app icon, and a message
instead of the app when neither WebGPU nor WebGL2 is available.
`cargo xtask wasm` (and so `cargo xtask ci`) now checks fieldcraft-web

what works in the browser and what does not.

The browser has no file system a page can call synchronously. On wasm32,
fieldcraft_io::fs now reads and writes files kept in memory (memory.rs,
after SolidCraft's vfs): the web host puts picked and dropped files in
and takes out what commands wrote. The recovery folder works over the
same calls (list, remove, is_file), with in-memory entry locks and a
host-provided clock on wasm, so autosave and File > Recover work in the
browser as on the desktop. Native behaviour is unchanged.

OK on a mesher's form ran the command on the window thread: octree hex
on the bolted assembly froze the window for over a minute, with no
progress and no way to stop it. The tet and hex meshers' forms now run
their command as a background job on a copy of the session, as opening
a file and solving do: the window keeps drawing with the job's name and
Cancel, the form closes when the mesh is in and shows the error when it
is not. ui.dialog {run} stays synchronous for programmatic callers.
The new test walks a first-time user's path: Open picks a SolidCraft
design, Tet Mesh opens its form, OK with the defaults meshes the part,
and a mapped hex mesh of a holed plate says why it does not fit.

The Open dialog is a native picker the control channel cannot click, so
nothing could walk a person's open path end to end: ui.start file.open
opens the command's JSON form instead. ui.drop {paths} hands the paths
to the next frame with the window system's drops, which open them
through the same route a picked file takes (open_path: by type, in the

The bracket's tet mesh is not bit-identical across platforms (#115): its fillet peak is 213.31 MPa
on macOS and 212.42 on Linux CI, which turned the oracle job red after #110. Those two quantities

The end-to-end demo met a raw-CDT sliver that the validity gate accepted (exactly positive) and
the solver refused. Now:
- One validity criterion, `fieldcraft_model::admissible_jacobian` (normalized Jacobian above
1e-12), used by the implicit solver (fem `positive_inverse`), the explicit tet4/hex8
kinematics and the mesh gate, which proves it on the whole element (tet4: the solvers' own
Jacobian; curved kinds: a Bernstein floor), so whatever passes the gate passes the solvers.
- CDT rounding repaired by flips on the rounded mesh (Diazzi et al. 2023 §5.1) instead of the
±2-ulp nudge.
- `fieldcraft-mesh::tet`: a mutable tetrahedral complex whose every change is a checked
replacement (positive and admissible tetrahedra, faces matched with opposite orientation) with
an exact undo log; edge removal (Klincsek), multi-face removal, Delaunay insertion with
boundary faces, edge collapse; a curvature- and thickness-graded size field; constrained
Delaunay refinement with encroachment splits; ODT smoothing; the Klingner–Shewchuk schedule;
boundary vertices moved onto the exact B-rep surfaces at the end; tet10 with mid-edge nodes on
the geometry.
- `mesh.tet.generate` gains size, order, quality, quality_target, curvature_angle, grading,
max_passes, max_points and reports the CDT's and the mesh's quality; `solve.probe` takes a set
and reports its largest von Mises stress.
- Oracle cases filleted-bracket-fillet-stress(-coarse): the fillet's peak von Mises stress on
tet10 meshes of 2k and 13.5k elements, 213.3 MPa (a four-level study stays within 1.8%); the
CDT cases keep the raw tetrahedralization.
- Corpus quality columns: all 20 valid parts mesh and pass the gate.

ui.select now also drives the viewport's selection: the filter, box
mode, items by name and label as model.set.create takes them, a pick at
a window point or the visible items in a box, changed by a mode
(replace, add, remove, toggle). ui.selection reads it back with its set

A push to the release branch (or workflow_dispatch) builds the macOS universal dmg and CLI zip,
the Linux tar.gz and AppImage and the Windows zip, with the version from Cargo.toml. The last

the files as a run artifact (dry run). macOS signing and notarization use the APPLE_* secrets

The corpus runs mesh.hex.octree's mesher on every part at 1/25 of its diagonal (the size of
the structured hex column) and reports hexahedra, the smallest and mean scaled Jacobian, the
mesh volume against SolidCraft's and the time; a part it cannot mesh gets the reason. The

Replaces the mesh with the octree all-hex mesh of a body, an imported surface or every body
of the open design, and tags boundary element faces with their B-rep faces so sets by
geometry resolve. Size, tolerance, refinement depth, element cap, attempts and optimiser
sweeps are validated and capped; the element cap defaults to the session limit
(`Limits::max_hex_elements`), which the hostile-params test keeps small. Body input and face
tagging are shared with mesh.hex.generate. The catalogue's Automatic Hex entry is ready.

`fieldcraft_mesh::octree::octree_hex_mesh` meshes any closed part with hex8 only:
- an adaptive 3-refinement grid (27-tree) with strong balance and closure, filled with
conforming node-marking transition templates (Schneiders; checked over all 48 symmetries);
- a core of grid cells kept clear of the boundary (the HybridOctree buffer rule), with
non-manifold cleanup and a genus check against the part;
- a feature graph from the B-rep (corners, curves, patches) and a partition-first map of the
core's boundary onto it, then two boundary layers: a padding layer and a pillow per patch,
so every face boundary and sharp edge is captured by element edges;
- a Garanzha-type untangling and fitting energy (shape term |J|^3/chi, a volume term and a
soft fitting term, deterministic across platforms), a compass search on the worst
elements and a certified repair; failures refine the grid near them and rebuild, within
bounded attempts and growth.
The output passes the certified Jacobian check of every element and a gate that the
boundary encloses the elements' volume; boundary quads carry their B-rep faces. Quality is
reported with the same scaled Jacobian as mesh.quality. Literature notes for each step are in
docs/meshing/literature.md (B1.6-B1.10).

solve.nonlinear follows a nonlinear static step in load increments: dead
loads and prescribed displacements ramp with the load factor, a pressure
follows the deformed faces (its load stiffness symmetrised so the
supernodal Cholesky stays), the consistent tangent is refactored every
iteration with an optional line search, and an increment converges on
force, displacement and energy together. Increments start from the
extrapolated last one, grow after fast convergence and are cut back on
inversion, a non-finite or growing residual, an indefinite tangent or too
many iterations; the step stops cleanly at the minimum increment, the
increment cap or the Newton iteration limit. Elements are assembled in
parallel in label order (same bits on any thread count). Results carry
Cauchy stress, logarithmic strain, the increment history and a displacement
frame per increment, which results.frame and the results panel show.
Trusses, shells, beams, plane stress, incompatible modes, temperature and
centrifugal loads are refused by name; couplings warn that they stay

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,

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

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

transfinite_grid_blended blends faces by the block's graded parameters, so

* 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

The isotropic elasticity splits into D_dev + K m mᵀ; an element-wise
discontinuous pressure is condensed out (p̂ = K M⁻¹ Gᵀ u), leaving
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
every hybrid kind, a block in uniaxial strain at ν = 0.4999 (exact), Lamé's
cylinder in plane strain at ν = 0.4999 (hex20 1e-5, tet10 1.3e-3, hex8
2.5e-3 vs the locking displacement hex8 at −80 %). Every non-hybrid result
of the test suites hashes identically before and after.

* Heat transfer and thermal stress: thermal materials, temperature BCs, heat loads, heat transfer and coupled temperature–displacement steps, solve.heat
Model: Material.thermal (conductivity, specific heat, expansion, isotropic or
per axis; reference temperature), BoundaryCondition::Temperature (dof 11),
loads SurfaceFlux, Convection, HeatSource and Temperature (a field in static
steps), procedures HeatTransfer { transient (θ-method) } and
CoupledTemperatureDisplacement; checks for missing conductivity/specific
heat/expansion. fem: heat conduction kernels (conductivity, capacity,
source, face flux/film, heat flux) on the DofLayout (one T per node), thermal
strain load and stress D(ε − ε_th) for every solid formulation incl.
incompatible modes. Solver: steady and transient heat transfer, thermal loads
in static steps, coupled steps (exact one-way coupling). Engine: solve.heat,
temperature/heat-flux result fields, probes. Decks refuse heat transfer by
name. Analytic verification: slab, source+convection/flux, thick cylinder,
erfc semi-infinite solid, free/constrained expansion, bimetal strip, coupled
step.

* thermal: strains in 2D elements and explicit dynamics
Plane::thermal_load and stresses_with for plane stress (εzz free), plane
strain (σzz = −D₃·ε_th) and axisymmetric elements, incompatible modes
included; the solver's 2D kernels take them. Explicit dynamics turns a
step's temperature loads into a per-element thermal strain rate (reached
linearly over the step) subtracted from each strain increment, so it feeds
J2 and Johnson–Cook updates. Verified: free expansion in every 2D theory
and element, a biaxially held plate, an explicit free bar (ΔL = αΔT L,
stress-free) and a clamped bar at −EαΔT, capped at the yield stress with
perfect plasticity.

* thermal: trusses take the axial thermal strain; keep the roadmap's M7 line
Truss::thermal_load and stresses_with project the thermal strain on the
member's tangent (Σ αₖ tₖ² ΔT); the static solver applies them to rod2/rod3
(#38). Explicit trusses take none yet and a warning says so.

* Native file pickers, background opening, drag and drop and recent files
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.

* Samples and one-click Solve: results reachable from the window
file.sample {name} opens a ready-to-run sample (the two parts, the cantilever with static and
frequency steps, the bar impact) in place of the model; solve.run solves every step in order.
Help > Samples, the empty viewport's start screen and the Tools > Samples entry open them
(asking first over unsaved changes); Solve runs in the background like a file opening and the
Results tab comes up. --sample [parts|cantilever|impact] on the command line.

* The Craft-family shell: title bar, workspace ribbon, browser, context panel, timeline
The window now follows SolidCraft's and VectorCraft's layout and themes:
- title bar with the mark, quick actions (File menu, save, undo, redo, Solve, search,
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.

* Shell polish, docs and licences
Menus painted as the family's (flat File menu with recent files, decks and samples), the
legend sized to its text, two-line panel labels inside the ribbon, glyphs the UI font has,
offscreen captures without fade-in, ui.start runs in-window file actions (samples, recover,
solve) but never a native picker, ui.select. Control protocol, architecture, ROADMAP, AGENTS
and ATTRIBUTION updated; THIRD-PARTY-LICENSES.txt with craft-ui and rfd.

* Title bar mark from the application icon; fluid steps and domains in the shell
The title bar draws the app icon's bracket (assets/app-icon/icon-small.svg's faces) as
SolidCraft draws its mark; the window keeps its title-bar flags after the rebase.
solve.run solves fluid steps too (solve.fluid); the browser lists fluid domains.

* 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.

* Title bar: Solve and tools at the right end; no traffic-light inset in full screen
The owner's feedback on the title bar: Solve, search, theme and help sit at its right end
before the version; on macOS the left group (mark, name, quick actions) moves into the
traffic lights' room in full screen, where there are none, and back when leaving it. The
layout is a pure function (bar_layout) tested for both states, narrow windows and custom
caption buttons. ui.fullscreen {on} for agents.

* 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.

The pending 2D LE1 case becomes a real one; the plasticity cases stay
pending with what they still need (static J2 for the collapse pressure,
the transcribed measurements for the Taylor bar).

The large-deformation explicit core of #42 (objective stress rates, updated
kinematics) moves the bar wave and rigid-wall impact results by a few 1e-4
relative; both still pass their references (u_end 0.034%, rebound KE
-0.54%). Fixtures updated deliberately for that change.

The oracle binary (modelcraft-testkit) runs each case's recipe through the
command engine, measures its quantities by JSON pointers into step outputs
or commands, compares them with the cited references and the frozen
fixtures, and writes docs/oracle.md. 20 theory cases (patch tests of every
solid element, Timoshenko cantilevers, Lame, Kirsch, beam frequencies,
torsion and bending through couplings, explicit waves and impact, CDT
invariants), 8 published benchmarks (MacNeal-Harder patch, straight and
curved cantilevers, thick cylinder, Scordelis-Lo with solids, NAFEMS LE1,
LE10, FV32) and 10 pending cases with citations.

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.
