A patch of quads already meshed on a face of the body (a neighbour's mesh)
is matched to the block faces on it: block vertices to its nodes (its
singular nodes first, then along its grid lines), block edges along its
grid lines, faces filled quad by quad. Those faces take the patch's
divisions and nodes, held through smoothing. mesh.hex.project takes
"fixed": [face names] and builds the patch from other bodies' meshes.

The reply's untagged_faces lists every face of the plan's bodies no
element face carries; the acceptance checks require it empty, and a
symmetric filleted base checks a set by every face of every cell (#494).

The image's face names came from one sample per source face (the first
element face's centre), so a source face whose sampled element face was
off it, or a sliver, mapped wrong and the true image face went untagged.
Each source face now maps to the image faces its own reflection covers,
and each element face to the nearest of those.

project_trimmed accepted the exact surface's point up to a fifth of the
nearest triangle's median edge off the face: on a tall fillet piece
(triangles 30 mm long) that let a point on a sibling piece of the same
cylinder count as on it, so every quad round the corner took the first
piece's name. The slack is now the triangle's own chordal gap to the
surface, doubled.
A face narrower than the elements (the sliver a corner boss leaves of the
inner fillet) gets one row of the quads it runs through, from the
neighbour with the most quads left. Tessellation::nearest_face finds the
face nearest a point.

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

(6.7e-13), the mirror conforming on the plane.

With a user's partition on a symmetric body, applying the whole body's plan cut it again by its
symmetry plane and mirrored one cell, leaving the other half unmeshed ("the mirror images do not
reach cell Base/b/a"). Such a body is its cells: the symmetry is not used and the plan is refused
with the cells named, as the replay of the saved Pi 5 model shows.

After geometry.partition cuts a body, the body is its cells: a projection plan of the whole body
could not open it and failed with "no body `Base` (open a design first)". It now names the cells
and says to plan and apply a cell (mesh.plan {"body": "Base/a"}) or delete the partitions. Tests
cover a design opened directly and a saved model opened again, partitioned after opening.

mesh.plan.apply finds the planes a projection plan's body is its own mirror image across
(through the middle of its extent, square to the sweep's in-plane axes, through no ring: every
triangle middle of its tessellation, a little inside and outside, has its mirror image inside and
outside alike). It cuts the body by them, plans and meshes the cell on their negative side, and
mirrors that mesh across each plane in turn (mesh.mirror, joined node to node on the planes), so
mirror-image regions mesh exactly alike. `symmetry: false` meshes the whole body.
A cell of a partitioned body is planned from the features that built its body, with the rings it
holds; a partitioned body is planned whole as before.

The compass search after the sweeps moves the nodes of the worst elements one at a time, each to
its own best place. Since it lifts every element below 0.7 (#462) it moves many surface nodes,
and a column of them on a face ends at scattered places: the enclosure base's inner walls showed
zigzag element lines in a column next to each corner, full height. A last pass now moves each
surface node back toward the mean of its neighbours on the surface, as far as no element round
it falls below the lower of its own value and the mesh's smallest after the search, so the lines
straighten and the mesh's worst element is no worse.

Projecting a point onto one B-rep face searched one box tree over every triangle of the
boundary, skipping the other faces' triangles: when other faces lie nearer the point than the
target face, it walked most of the tree before reaching a triangle it could use. Smoothing a
projected mesh projects every boundary node many times, onto every face of its target group,
so the Pi 5 enclosure base spent 95 % of its 11 minutes there. Each face (and each face pair's
curve) now has a tree of its own: the same nearest triangle, found among its own boxes only.
Ties between triangles at the same distance went to whichever the tree's walk met first; they
now go to the lowest triangle, so the result no longer depends on how a tree is built. With
that rule the per-face trees and the whole-boundary tree give bitwise the same mesh.

The crank arm's back pocket ends on the planes x = 48 and x = 130, its frame sides. The plan
put its frame cuts there; the kernel cannot cut along a face (#427), so both were skipped and
the cell between the bosses swept the pocket's rounded ends into fans. A frame side on a face
of the body now moves one element out of the opening (away from the rectangle's middle),
leaving a strip one element wide; both cuts are made.

#462 visited nodes by a mirror-invariant key (distance from the centroid). On the cup with a
handle that order sweeps ring by ring round the axis and converges worse in its 100 sweeps: the
refined cup fell to a scaled Jacobian of 0.481 (needs 0.5, #440). In the lattice's own order
it holds, and the order gained the enclosure base little (its corners differ by 0.02 either
way), so it goes; the compass search's lift to 0.7 stays.

The compass search after the sweeps only lifted elements below 0.5 (the quality floor), so a
mesh whose worst elements sat just above it stayed there: every corner of an enclosure base
stopped at a scaled Jacobian of 0.50-0.52 where its walls meet the corner bosses. It now lifts
every element below 0.7, never lowering another below the lower of its own value and 0.5.
The sweeps and the search are Gauss-Seidel, so the node order shaped the result and mirror
image corners smoothed differently. Nodes are now visited by a key that a mirror or a quarter
turn about the nodes' centroid keeps (distance from it, then the sorted offsets along the
axes). What spread is left between mirrored corners (0.686 vs 0.702 on the test base) is most likely the projection onto the body's
tessellation, which the kernel does not make mirror symmetric (not yet proven).

The crank ends at 8, 16, 20 and 22 mm, so no one-to-one sweep takes it.
The sweep met one of those caps as a linking face and reported "linking

A boss the body's walls run into had its circle crossed by the walls' planes, so the projection
layout refused it and the plan fell back to swept cells, fanning round the boss and its hole.
Such a boss is now framed by the square round its whole circle, subdivided by the planes that
cross it; every square inside (the hole's, the core) is divided alike, so the ring's blocks meet
the walls node to node. On the walls' side the frame stops at their inner plane and its corner
projects onto the middle of the inner fillet, which the ring takes in (a boss just touching the
fillet included: no sliver). Cylinders a fillet's history names but that are a ring's circle are
the ring's faces. Rings are built per patch of grid cells, the one-cell O-grid being the
simplest patch.
