Seed 31: #1581 refuses a fillet selection with an earlier round's smooth seam instead of re-rounding another nearby edge. Seed 83: #1316 was recorded before its branch took in #1495, whose shell keeps the wall beside a concave edge.

* Chamfer: refuse a result that grew a convex edge's part (or shrank a concave one's)
A chamfer of a curved edge that runs off a face it skims (robustness seed 57's
ball rim) built a part bigger than before. Checked from the two faces' normals
at the edge; rounds and unclear angles are left to the wedge bound.

* Action matrix: the sheet metal tray's relief corners refuse a 0.25 mm chamfer
Each is a 2.5 mm concave edge (the corner of a corner relief, between two
planes at right angles): a chamfer there fills at most 0.25²/2 × 2.5 = 0.08
mm³. What was built took 0.95 mm³ away; the chamfer guard now refuses it.

* Robustness goldens: seed 57's wrong-way chamfer is now refused (#1390)
On main with #391, seed 57's chamfer grew the part; this refuses it, so the run goes on
to its later steps and ends ok.

A point within the point tolerance of a boundary curve's end is that end in the boolean, whatever its parameter, so text cuts no longer leave unmatched sliver vertices (#391). Robustness goldens re-recorded for seeds 0, 34, 39, 41 and 57 with reasons.
A round or chamfer whose edge chain runs on across a curved seam (the end circle of a lofted tube whose axis bends) is now built: the section solve keeps its contact on the seam through a plane taken afresh at the seam's nearest point at each step. Straight seams are unchanged. Robustness seed 41 is re-recorded: its second fillet, refused before, now builds. Fixes#1213.

#1164 joins a body that sits flush on a rounded rim into it. In seed 13 the
rectangular pattern's second box (x 5..7.5) sits flush on the half-ring's top
face with a 27 mm2 contact patch. It used to stay a separate shell (one body,
three shells); now it joins the ring (area -54 mm2, twice the patch). The
fillet edge and hole position the generator picks next come from the new
geometry, so the end state differs: 3 bodies, 2647.95 mm3 (was 4, 2300.91).
Every step stays a sound solid, and no other seed moves.

* Fillets and chamfers meeting at corners on curved faces, on top of #935
What #935 and #926 leave of #851 and the matrix:
- Corner build for blends meeting on faces of any surface (curvecorner.rs):
the knife-edge tip's round with the arc's or the back edge's, edges
picked in any order, a round ending in an earlier round of its radius
(as a feature of its own), and chamfers meeting at the arc's corner.
Its end curves are fitted by chord length: a uniform parameter
through points clustered at the ends doubled back on itself there,
and the display planner refused the face.
- A straight edge ending at a curved face (the back edge into the
knife-edge tip): rolled, or cut by the face in the planar corner
build (blend_corner.rs).
- A rolling ball turning about a rounded corner of its own radius
(a pivot: a piece of sphere or cone).
- Seams that are an earlier blend's straight contact (fitted curves)
count as straight.
- No spline across a joint where the strip's curvature jumps (a line
into a small round): each strip ends on the joint's section.
- Sections at a chain's vertices on the faces of the edge from it
alone.
- Every new fillet path passes #949's check for openings.
Tests measure volumes through the display plan, as #935's do.
Action matrix: 51 more fillets and chamfers pass (sweep, tangent arc
chain, sheet-metal hem, bracket holes), none fewer. Robustness seed 33
recorded (its last fillet builds differently; display and measured
volumes now agree).

* Corner blend tests: scale, seed 33's volumes, tighter engine bounds
From the review of #854:
- seed_33_display_plan_and_measure_agree: seed 33's bodies measure
the same through the display plan and the measure (2e-5), which the
golden's re-record rests on.
- the_arc_rounded_after_the_back_edge_matches_both_together: the order
that still leaves 0.05 mm³ at the tip, as an ignored test.
- corner_blends_hold_at_any_scale: the cases this branch adds on the
#851 part, at 0.01x and 100x, take off what they take at full size
times k³ (within 5e-6, checked to 1e-4).
- The engine tests on the part as drawn measure through the display
plan; bounds are about twice what each reads (2e-4 to 3e-3), and the
front corner's sets are checked against the kernel's CSG grid.

#970's lenient retry of a face's parameter boundary searches the whole surface as a last resort; on robustness seed 20 it found an edge's points across a cylinder's seam, half a turn apart, and the Cut failed. A lenient boundary whose points jump half the parameter range or more is refused, and the face is left undivided as before (#970's elbows step at most a fifth of the range). Seed 81's volume moved by 0.1 mm3 with #952's hole direction; recorded.

Touching sews now split 4-use straight edges on extruded walls (along their rulings), not only on planes. Faces round such an edge are ordered by the way they leave it and, where they leave it tangent, by their curvature. Sheets bound the material wedges as before, except where that would make a face touch itself (a hole touching the outline from inside); edges ending there pair the empty wedges instead, so each loop gets its own vertex. Coincident faces are still refused, plain sew still refuses vertex contact, and shell_groups is unchanged.
A Ø10 hole tangent inside a stepped Ø40/Ø20 boss now cuts exactly instead of failing with "wire is not simple". Robustness seeds 42 and 51 are recorded: their touching hole patterns in stepped bodies now cut exactly instead of by a tool nudge.

* Boolean nudge tried both ways: no sliver where a cut's end touches a round side (#897, #827)
Robustness seed 14 cuts a cylinder whose end lies exactly on the apex of the
plate's arc side. Since the display tessellation plans (#805) the generator sees
the arc's true extent, so the cut's base lands on -10 instead of -10.000000000000002
and the end is tangent to the arc. The direct boolean fails there and the
last-resort tool nudge pushed the end into the arc, leaving a planar sliver a
tenth of a millimetre wide; shell then picked that sliver and refused it. The
13 October merges were not the cause (the bisect lands on #805).
The nudge is now tried both ways and the simpler result (fewer faces) is kept,
so the opposite nudge parts the touching faces instead. The same change joins
the hinge barrel in #827, whose top lies tangent to the lid's underside where
the mounting leaf ends. Each result still passes the same checks as before.
Goldens: seeds 14, 26 and 85 now build to the end, 31 and 78 come out with
fewer faces. Seeds 6, 43 and 73 still stop at shell: their joins now succeed and
shell reaches corners it can't offset (a cusp where a box face touches an arc,
coplanar faces facing opposite ways), which is unchanged.
Fixes#897Fixes#827

* Nudge the other way only when the first nudge fails or leaves a sliver
Trying both nudges and keeping the one with fewer faces could prefer a result
that keeps two pieces joined by a hair over one that separates them (the
centred coplanar revolve cut). The opposite nudge now runs only when the first
one failed or left a face narrower than 1/200 of the part, and it is taken
when it works with fewer of those.
Goldens re-recorded on current main: seeds 14, 26 and 85 build to the end,
31 and 78 with fewer faces. The other changed seeds are main's own since its
last full record, identical with and without this change.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Nudge the other way only for slivers the nudge made
On the sensor enclosure's lid the first nudge left thin faces the operands
already had (thin walls, small rounds), so the opposite nudge ran a second
boolean for nothing and the press/pull took 79 s against main's 55 s. The
opposite nudge now runs only when the first one failed or left more slivers
than the operands brought; the press/pull test takes 36 s against 42 s on main
(same machine, one after the other).
Goldens re-recorded on top of #940.

* Hole matrix: placement, types, extents, edits and 0.9.0 designs, with today's failures listed
Each case checks the drill goes into the material, the bore sits on its axis, a blind hole stops
where it should, the removed volume against its analytic value, the face count and that every
body is still one closed valid solid. Failing cases are listed in tests/hole_matrix/known_failures.txt
as a ratchet.

* A hole on a face drills into the material, also in older designs (#950)
Without a direction, solid.hole took the direction from any face whose infinite plane passed
within ten tolerances of the point, the last one found winning: the far side of a thin plate or a
face of another body at the same height could set it, and the wrong direction was saved. It now
uses the face nearest the point, against its outward normal (exact for planes, cylinders and
spheres, so holes on curved faces work without a direction). When a design is evaluated, a face
hole whose saved direction leaves the face it starts on is mirrored into it, so designs saved
with the wrong direction drill into the part.
Fixes#950.

meets a cut the kernel refuses are marked failing.

#921's grid lines through the vertices that split a ruling edge also went into the meshes Boolean operations intersect, which changed seven robustness seeds (seed 2's sphere cut failed). Deflection::rulings now asks for them only in the kernel's own tessellation (display, export, measurement). The seeds #936 (rejected instead of unsupported), #946 (26 and 85 build, others fail differently) and #921's display side (about 1e-6) moved are recorded with their reasons.

Rolling-ball blends now handle knife edges, where the two faces have opposite normals; an edge that runs out along an end face tangent to one side; and rounds that end in an earlier round on curved faces, picked together or one after another. The three edges at a vertex of smooth faces, rounded to one radius, end in a piece of sphere. When the given order of up to four edges is refused, or leaves a face boundary off its surface, other orders are tried.
Closes#851.

* Fillet and chamfer: refuse a smooth seam as having no corner to round
Picking the seams where R10 rounds run into the faces beside them, and asking for an R1
fillet there, failed with "not supported yet: blending a smooth edge (... both faces next
to the edge must be planar)". That reads like a missing feature, but the faces meet
tangentially at those edges and there is nothing to round.
An edge whose two faces are tangent along it is now refused as an invalid pick that names
the edge and asks for the sharp edges.
Fixes#896.

Main has failed the full robustness goldens since #838, #839, #841, #855 and #856 landed together. Records the eleven seeds that now build differently (2, 6, 14, 22, 36, 43, 50, 63, 71, 73, 94), with a note. Shell now refusing seed 14, which used to build, is tracked in #897.
tests/robustness/goldens.json records what each of seeds 0-95 builds: its steps, how it ended (ok, or the kind and the start of the error it was refused with) and, for the design it left, the bodies' total volume and area (within a relative 1e-6) and their face, edge and shell counts. tests::robustness_goldens fails on any change; ROBUSTNESS_GOLDENS_BLESS="why" records one, with the reason and the seeds it moved. Pull requests that touch crates/kernel run every 8th seed; pushes to main and the nightly run every seed.
