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).

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

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 desktop app installs the crash reporter and a log file at start
(both in a temporary folder in --control and CI runs, #266), journals
the window's commands (background jobs included) and every control
request's method, and ends the journal on a clean exit. A start after a
crash asks: "FieldCraft closed unexpectedly", Report It… or Not Now.
Help › Report a Bug (also Tools › Help and ui.start
diagnostics.bug_report) shows exactly what the GitHub bug form will be
filled with: the version, the OS, the last error, and for a crash where
it happened. Share my session adds the replayable commands, Include the
model file the model. Open GitHub Issue opens the form in the browser
through the system's opener; files to attach are saved to
bug-reports/<time>/ and a long session goes on the clipboard. Nothing is
sent without that click and the user's submit on GitHub.
The control channel answers the new prompts (crashed: report, close;
report_bug: set, close) and ui.inspect shows the draft; it never opens

unclean exit found at the next start (abort, segfault, a crash in a

journal starts from (autosave, file or a copy) and the commands since,
the last control request and the dead run's log lines. Reports are
bounded, deduplicated by signature and replayable (crash::replay, with
writes confined to a scratch folder). The crash folder follows the
automation temp area in --control and CI runs.
logfile: a small size-rotated file logger behind the log facade.
bug_report: GitHub bug-form drafts. Version, OS and what happened by

crank-arm (and crank-mirror, kept as the same model under the name of

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

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.

Zoomed in on the hex20 crank arm, the element edges and the shaded faces
did not meet (#260). The mesh is conforming; the display drew each hex20
face and edge as straight chords between corners while the mid-side
nodes lie on the curved surface (up to 0.44 mm off the chord at 3 mm),
and drew the geometry's face boundaries from the design tessellation,
off both.
Now a quadratic face is cut into triangles whose vertices are its
corners and mid-side nodes, each edge is drawn as its two halves, and
over the mesh the geometry's edges (and a hovered design edge) are drawn
as the element edges on geometry edges (`DisplayEdge::feature`), so
faces, edges, feature lines and the highlight share their vertices.
