One formatter (four significant digits, thousands separators, round-off as
0) and the model's units through every results readout:
- legend title with its unit, a mode shape normalised; Max/Min with units,
clickable to show and probe the node; markers at both in the viewport
(#321, #330)
- the deformation scale field shows the scale Deformed would use, never 0,
in the shared format; true scale named (#325, #326)
- setup symbols off over results by default (Show › Loads & BCs), and then
only the shown step's (#327)
- reaction sums in the results panel however they are run: per set and in
all, force and moment with units, applied beside reacted (#328)
- the probe: U [mm], |U|, Mises, stresses and principals with units, the
label kept inside the viewport, rows in the results panel (#329)
- hiding the mesh over a plot hides the element edges, not the contours
(#317); a hidden body's contours go with it, the range follows what is
shown (#365)
- the solve summary: peaks with units, n/a rows left out, counts grouped,
internals under Details (#321, #319)
- the energies plot: axes with units, a cursor at the frame (click or drag
to move it), hover to read (#331)

- DisplayMesh::from_model_hiding leaves out a hidden body's elements (and the
nodes only they use); Session::hidden_elements names them, so the viewport,
probing and headless pictures skip hidden bodies (#365).
- A solve summary's applied and reaction totals set the round-off of
cancelling sums to 0 (#319).
- results::principal for the probe's principal stresses (#329).

- Quantity names the unit of every number the results show from the model's
unit system (mm, MPa, N, N·mm, mJ, mW, °C or K); Field::title puts it in the
legend title, and calls a mode shape normalised (#321).
- A solved step's result stays current through edits that leave what it reads
alone (Model::step_inputs: other steps and what only they use), and comes
back current on undo (#318).
- Session::step_glyphs: the symbols of what a solved step used, for drawing
over its results; no load arrows on a frequency step's modes (#327).
- Nonlinear static steps open deformed at true scale like explicit ones, and
their automatic scale is 1 (auto_scale, shared by the viewport and the
headless pictures) (#326).
- results.reactions with an empty sets list sums the step's boundary-condition
sets, as its form says (#328).

a selected vertex is marked (#346).
- Use selection on Datum Point (vertex, edge, face, or a hole's centre)
and Reference Point (geometry.centre: a hole's centre, a vertex, nodes)

- Partitioned Mesh: Use selection takes the picked bodies as cells; the
cell list has All, None and Invert; hovering a cell's row (or its method
row) highlights the cell in the viewport (#344).
- Rigid Wall's form takes its set from the selection; the Interactions

SolidCraft names the pieces of a split body by stacking suffixes
(Bracket (1) (1)' (1)). On opening a design, the pieces of one body are
named <body>.1 … <body>.N, ordered by centroid, so the tree, tooltips,
forms and picks read as one part with numbered cells.

Meshes that do not tag their element edges with the design's edge names

The design file stores no measure to compare with, so the rebuild's own
failures are the guard: each failed feature lists the bodies it names (all of
them when it names none), and geometry.open replies with a warning per failure,

- A solve or a mesher runs as a job with one progress mechanism: the overlay
shows the step, stage, count and elapsed time with a bar when bounded, OK
waits while it runs, and the status sums it up (elements, smallest angle,
time) (#322, #357).
- Over the control channel such a command is a job too: answered when it
ends however long it runs, or at once with wait: false, then job.status,
job.wait, job.cancel; ui.inspect gives job; MCP waits for it (#367).
- A command that cannot run yet lists what it misses in the context panel,
each with a button to the command that provides it (#323).
- A cancelled or refused solve stays in its workspace (#324, test).
- A mesher form starts from the parameters of the mesh it would replace (#343).
- Seed Edges and edge/vertex/face datum points switch the selection filter
while open and restore it (#341).
- Datum forms draw the datum live, the Partition form shows its datum, and
new datums and partitions get the next free name (#347).

The setup checklist marks the mesh Outdated (a warm ⚠ in the browser, with

changed after the last mesher ran, and model.check warns (#342). Replacing

fieldcraft_model::progress: a host installs a Progress on the worker thread

the nonlinear solver its load factor, the explicit solver its time, the

stage and pass. Without one installed every report is a no-op (#322, #357).

A checkbox whose key is unset shows the field's default (#353). An empty JSON

A non-zero prescribed displacement is an arrow leaving the nodes along the
motion (its held degrees of freedom stay supports); a prescribed temperature
is a thermometer, convection a wave off the faces, a heat flux an arrow onto
them. In the tree, thermal conditions carry the heat icon and a moving
boundary condition a motion arrow.

members and what they resolve to), for the context panel.
- reply::done: status lines that say what changed ("Showing Load deformed",
"Mode 2: 1637 Hz", "Added material Al").
- The context panel puts the form and the selection above reports; opening
another document clears both; what a form makes is selected.
- Use selection reuses a set with the same members, otherwise names one made
on OK; Cancel leaves the model unchanged. The Target's set row is labelled.

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.

The release job signs SHA256SUMS.txt into SHA256SUMS.txt.minisig with rsign2 when the
FIELDCRAFT_SIGNING_KEY secret exists, and checks the signature against the public key the app
is built with; without the secret the draft is unsigned, the run warns and the notes say the
app cannot install that release itself. docs/releasing.md says how the key is set up, kept
and rotated; docs/updates.md describes checking, verifying and installing, the web app's
Reload to update, and FIELDCRAFT_UPDATE_HOST for tests. privacy.md, control-protocol.md,

Every half hour the page fetches its own address past the browser's cache; when it loads
another content-hashed build of the app than the running one, the status bar offers "Reload
to update" (the page's unsaved-changes question still guards the reload). Rust only, no
service worker: the browser build has no other update path and none of the desktop's

The desktop app checks, downloads, verifies and stages on its own threads for the window, and
once the window has closed (autosave closed) swaps a staged release in and starts it. Staging
folders an earlier update left are removed at start-up. Automatic checks stay off under

The window checks at start-up at most once a day when automatic checks are on (Settings and
the first run's question), never while that question is open and never without a host, so the
browser and tests make no network call. A newer release shows a quiet notice in the status bar
("FieldCraft X is available — What's new · Install · Skip"); Install downloads and verifies
through the host, then asks to restart, saving or asking about unsaved changes first, and the
host swaps the release in after the window closes. A .deb/.rpm install offers the system's
installer and the command instead. Skip this version is kept in the preferences.

The extrusion's automatic cross-section blocks reach both commands; the
half crank arm, cut only on its symmetry plane, meshes all-structured
(sJ >= 0.37) with no seeds either way, and mesh.hex.generate's
description says so.

A region of an extrusion's (or revolution's) cross-section that no
structured scheme fits is now cut by straight lines into blocks that fit,
before interval assignment, so the cuts are curves of the arrangement and
their counts are assigned with the rest; nothing reaches the model
(hex::decompose, after Tam and Armstrong's medial-axis subdivision and Li,
Armstrong and McKeag's primitives).
Per region: several holes are separated by lines across the gaps between
neighbouring holes; a piece with one hole gets the O-grid layout whose
pieces score best (lines from the outer corners towards the hole or along
their bisectors, from the hole's corners, or along four directions from
the hole); pieces without holes are cut by a two-ply search over lines
from concave corners and fillets and from convex corners. Candidates are
scored by meshing the pieces with their schemes (smallest corner scaled
Jacobian). A region's blocks are kept when fair (at least 0.5) or no worse
than its free mesh, and cuts never end inside a seeded curve.
This replaces the cuts from reflex corners along an edge. Tests on an L,
a T, a plate with a hole, with a slot and with three holes, and the half
crank's cross-section: every region structured, the quads conforming and
the smallest corner scaled Jacobian bounded. The half crank arm now
extrudes in 12 structured regions with a hex20 minimum scaled Jacobian of
0.37 (the arm meeting the bosses 20 degrees off tangent bounds it) where
it had 2 free regions and 0.009.

The schemes, interval constraints, curve nodes and region meshes of a
multi-level sweep's cross-section move out of layered::mesh into
hex::section, with the curve placement (seeds, projection onto walls)
passed in, so the cross-section can be meshed on its own.
region::mesh_structured gives a scheme's mesh or None where it would fold,
without falling back to the free mesher. No change in behaviour.
