pull-request jobs skip drafts, so a contributor's work in progress no

harmonic function of the element-edge graph, zero beyond the radius and at

each node move (faces in UV, edges along, vertices held), scaled back by
bisection until no valid element inverts, and reports each element's scaled

The dihedral range and mesh.quality's scaled Jacobian were both right:
they are computed by the same function on the same final corners (tet4
and tet10 give identical numbers), but a dihedral range does not bound
the corner scaled Jacobian. A needle has dihedral angles near 60 and 90
degrees and a nearly flat apex corner. Before 417c0c88 sphere-on-plate
at size 4 had dihedrals 36.3-141.6 and 106 needles below SJ 0.2 (min
0.095); now 36.0-137.6 and min SJ 0.351.
The mesher's report now carries min_scaled_jacobian so it cannot read
as all-good while needles remain.

The improvement objective was the smallest dihedral sine, which misses
needles: every dihedral angle fine while a corner is nearly flat, so
the corpus meshes had scaled Jacobians down to 0.01-0.07. The objective
is now the smaller of the dihedral sine and the scaled Jacobian at the
worst corner (the measure analysts check, Knupp 2001), weighted so a
Jacobian of 0.3 (the skill's limit) counts as a 30 degree dihedral
angle (the schedule's target): the Jacobian decides only near that
limit. The existing edge removal, multi-face removal, smoothing and
insertion then remove the needles.
Skill tet10 min SJ: sphere-on-plate 0.092 -> 0.335, filleted-bracket
0.021 -> 0.318 (both pass, nothing marked). Default-size tet10:

Where a tie's secondary surface meets a boundary condition or an
axis-aligned symmetry plane (a crosspoint), the secondary node's motion
is already prescribed and its mortar row can only constrain main
degrees of freedom. Its weights on main nodes off the boundary do not
vanish (the dual basis spreads over the node's faces), so after the
substitutions a small but real constraint is left: 1.3e-6 of the
coefficients that cancelled to give it on the tied hex-tet bar with
the needle-aware tet mesh (round-off would be ~1e-14; the geometry is
exact). It was refused as a near repeat, which made the tied bar
depend on how the tet faces fell. It is now dropped (the tie is then
off by that fraction at the crosspoint), after checking it does not
contradict the prescribed values. A near repeat on a secondary degree
of freedom another constraint eliminated (a node secondary in two
ties) is still refused (#389). Dropping every held secondary node's
row instead fails the tie patch test, so only near repeats go.

Owner's rule (#438): move the bad nodes, interpolate, keep the morph as long as no
element inverts (guards "valid", the default); the old guards stay as "strict". The
run keeps its best round (highest smallest scaled Jacobian, then fewest elements below
the threshold, then highest mean) and never ends below the start. Default reach five
mean edge lengths of the bad elements (was three); on the Pi 5 base reach 3, 5 and 7
end at the same quality, 5 moving fewer nodes than 7 while leaving none below 0.7.

Deleting a cap tetrahedron (two boundary faces of one B-rep face) gives each of its
two other neighbours a boundary face; a neighbour that had three was left with every
face on the boundary, joined to the mesh by its vertices alone. On Linux the dome on
a plate (cmd::plan::decompose::tests::a_dome_on_a_plate...) got one and the static
solve found the stiffness singular. The kernel's tessellation and sphere parameters
differ in their last bits between macOS and Linux (SolidCraft, outside this repo);
given the same input the tet mesher gives the same mesh on both (checked by replaying
Linux's surface and spheres on macOS, which reproduced the floating tetrahedron).
The deletion now refuses when a neighbour would float, and the linear validity gate
fails a mesh with a tetrahedron that shares no face with the rest, saying so.

In the max-min phase a valid element's term q^-16 reached 1e96 as q -> 0+, far above
an invalid element's 2e8, so the descent kept elements inverted rather than pass
through flat: the distorted plate stayed tangled (4 invalid) once its mesh was the
same on every platform. The shape term now continues as its tangent line below
q = 0.3 (finite, steep) and an invalid element costs 1e11, above any valid one.
Adds a test that the plate's mesh, its perturbation and the strong relaxation are

The system maths library's sin, cos, atan2, log … are not correctly rounded and differ
between platforms: mesh.hex.generate gave the plate of the strong-relax test a different

SolidCraft lists a solid's faces in a different order from run to run
(the rounded box, for one), which reordered the triangle soup and the
face tags with every coordinate the same; welding keeps the first copy
it meets and every later stage visits ids in order, so the tet mesh
changed between runs. CanonicalSoup sorts the triangles by their
coordinates, numbers vertices by first use and face tags by first
appearance, and maps the tags back; mesh.tet.generate and the corpus
use it.
Tests: the washer's tet10 mesh has a fixed fingerprint (identical on
arm64 and x86-64 builds); a reordered, renumbered input gives the same
mesh; heavy: rounded-box and filleted-bracket mesh bit for bit the same
on repeated runs and with 1 and 8 threads.
The bracket oracle cases stay unfrozen: SolidCraft's tessellation
itself differs in the last bits between arm64 and x86-64. The coarse
case moves to 203.6 MPa with the canonical order; its band is 5%.

A merged face on several surfaces (a sliver absorbed into its neighbour)
had no exact surface, so the projection target fell back to its
triangles: flat curvature probes gave fewer divisions round the boss and
the enclosure base's symmetric mesh dropped from 0.70 to 0.51 once its
absorbs reached the cells. The target now projects a point of such a
face onto the exact surface of the B-rep piece it is on, trimmed to that
piece (Tessellation::with_pieces, Shape::tessellate_pieces); node

The extrude/revolve cross-section took both ends of every B-rep edge as curve ends. A closed
edge without a vertex on it (a hole's rim after geometry.faces.merge of its halves) starts
wherever its chain was picked up, the old seam vertex, so that point stayed a curve end and a
node column stayed on the merged boundary. Only open edges' ends (and the B-rep vertices) are
curve ends now; the layout and interval assignment place the rim's nodes.
The hex test runs on a square plate and asserts the seams carry exactly as many nodes as the
same lines turned a quarter round the hole (10 and 10; before 5 and 10): the corner layout
puts arc-midpoint nodes there by symmetry, so 0 is not the right target.

When the grid layout does not fit a swept body (sides at an angle to the axes, root arcs where
an arm meets its bosses), mesh.plan tries the ring-and-pillow layout (cmd/plan/pillow.rs): each
boss is an annulus from its bore or pedal hole to its circle through every level, the arm a grid
carved a margin inside the outline and the bosses, with a pillow layer of blocks to the wall each
boundary face faces; a grid corner facing a boss and the outline gets a corner block reaching the
kink where the outline leaves the boss's circle. The old crank test (frame cuts) becomes the
heavy acceptance test at sizes 2.5, 3 and 4; the moved frame cut keeps a unit test.

model.boundary_condition.symmetry takes a datum plane of any orientation,
finds the faces on it and reports the plane's unit normal when it is
inclined; the glyph draws a support along that normal. Verified: half a plate
cut on its diagonal with the plane deflects as the half mirrored across it
(6.7e-13), the mirror conforming on the plane.

At an inclined plane's nodes the velocity along its normal is removed every
increment, from the components no prescribed velocity holds (planes meeting
at a node orthonormalized, so one pass is exact); a prescribed motion off the
plane is refused.

The symmetry condition takes any plane normal ({"normal": [nx, ny, nz]}).
An inclined one holds n·u = 0 and, at shell, beam and reference point
nodes, the rotations about the two in-plane axes: constraint rows the
implicit elimination already handles, its support forces reported as
reactions. Decks: Abaqus *EQUATION, Nastran MPC sets per subcase, LS-DYNA
*BOUNDARY_SPC in a *DEFINE_COORDINATE_SYSTEM along the normal.

The updater's release endpoint, docs, README, release notes and the Pages
URL point at the tangency-labs org. App IDs (io.github.jyviko.fieldcraft)
stay unchanged so installed copies keep their identity and settings.

Use selection puts the selected design faces in the form as faces, in
place of a sphere; Shift/Ctrl-click picks faces while the form is open,
and every click does once the form lists faces.

mesh.node.relax takes faces: [{body, face}] (every node on those B-rep
faces and the nodes of the elements touching them, sliding on the faces)
and elements in its form; the undocumented-by-form set is dropped.
A schema test checks every top-level key a params doc names is accepted,
which also found mesh.hex.extrude normal, mesh.hex.project max_arc_angle
and mesh.plan.apply name missing from their forms.
