83c31d77c4 surface.boundary: surfaces through boundary curves and curve networks (#763) (#2129)
* feat(geom): surfaces through curve networks, and spline spaces to build them

Adds spline_space (clamped B-spline spaces, Hermite interpolation, exact
embedding by Bézier degree elevation and knot insertion, a monotone cubic
for reparameterising) and network (loft, Coons and Gordon surfaces through
curves in one or two directions, with G1/G2 cross-boundary conditions
against a neighbouring face). Part of #763.

* feat(kernel): boundary surfaces from sketch curves, 3D curves and edges

kernel::boundary_network turns sketch chains, 3D sketch polylines and edge chains
into network curves, gives G1 frames of the faces along open edges
(EdgeFaces), builds the B-spline face (sides split at chain vertices so a
join shares the body's edges) and joins it into a surface body by stitching.
G2 is refused for now (not supported yet). Part of #763.

* fix(kernel): second derivatives of B-spline surfaces in the vendored truck-geometry

BSplineSurface::uuder and vvder multiplied the second differences by p
instead of p·(p − 1), as BSplineCurve::der2 does, so every surface of
degree p ≥ 3 (NURBS too, through its homogeneous surface) reported
1/(p − 1) of its second derivative: a cubic surface's curvature read as
half. This is why a G2 boundary surface on a cylinder measured half the
curvature it carries (#763). New tests hold both to finite differences
for degrees 2 to 5.

* feat(kernel): G2 boundary surfaces against a body's face

The network always carried the face's curvature across a G2 edge; the
refusal came from measuring it with truck's halved surface second
derivatives (fixed in the previous commit). EdgeFaces now reads the
face's second fundamental form from the exact second derivatives
instead of differencing the normal. A new test holds the curvature
across a cylinder's edge to the cylinder's within 0.1%, also with a
sheared far curve; G3 is refused (a network holds up to G2).

* test(kernel): a boundary patch with straight corners measures its own area

A stadium's arcs meet its lines at 180°, so the Coons patch is singular
at its corners. From such a corner the reference mesher's boundary walk
ran onto the B-spline's extrapolation past its domain (a planar spline
passes through every point of its plane there), and the face measured
289 mm² for its 158.5 (#763). The vendored mesher's bounded projection
(nearest_projection, #2043) keeps the walk on the domain; this holds it
there, by the faces, the measuring mesh and the display mesh. The
display path (#1653) was never affected.

* feat(geom,kernel): three-sided boundary surfaces (one side collapsed to a point)

A network curve may be a PointCurve: the apex where the two sides beside
it meet. The curves through it cross it at the point itself, its row of
the net collapses there, and the kernel's face leaves that side out of
its loop (three edges, one vertex at the apex). One point per patch, as
a side; refused elsewhere, when it moves, or with a continuity
condition. Tests: a triangle and a quarter disc filled flat with their
analytic areas (40 mm², 25π), by geom and by the kernel's faces and
meshes.

* feat(doc): boundary surfaces through curve networks and loops of three or four

FeatureKind::SurfaceNetwork saves a network as `u` and `v` curves, each
a sketch chain (planar or 3D), a chain of a body's edges with an
optional G1/G2 continuity, or a point (the apex of a three-sided
patch), and an `operation` that can join the surface into the body of
its edges. A SurfaceBoundary of three or four sketch curves, refused
until now, builds as the flat Coons patch of its loop (three collapse
the side opposite the first curve). The format change is one pending
file; feature-walk goldens record the new variant's sketches, bodies
and points.

* feat(engine): surface.boundary through loops of three or four and curve networks

The command keeps its loop form (two to four curves of one sketch; three
and four now build the flat patch of the loop, crown refused there) and
gains a network form: `u` and `v`, each curve a sketch curve id, a
{sketch?, curves} chain (planar or 3D), a {body, edges, continuity?}
edge chain (g1/g2 with the face beside it) or a {point} for a
three-sided patch, with `operation` new or join. Edits may move between
the two forms (timeline.redefine accepts the command now that it has a
dialog).

Tests: analytic areas of loop patches and of a hyperbolic paraboloid
bounded by four 3D lines (every mesh vertex on z = xy/10), a loft
across two sketches, G1 and G2 measured across a cylinder's edge with
inspect.continuity (angle < 0.1°; curvature jump 1e-16 with G2 against
0.027 with G1), 26 hostile networks refused without panicking, and u/v
added to hostile_params_never_panic.

* feat(ui): Boundary Surface dialog

Curves and Cross curves take sketch curves and edges (picks that meet
end to end in one sketch or body are one chain); Continuity and
Operation (New Body or Join). Two to four sketch curves of one sketch
with nothing across are the loop patch; anything else is a network.
Edit Feature brings either back (per-side orders, crown and stations
the dialog does not show are kept). Strings in en, ja and zh.

* test(oracle): a boundary surface through a loop, thickened (#763)

Case 83: four sketch curves (a square's three sides and a half circle
for its top) make one boundary surface, thickened 2 mm; analytic values
from tools/oracle-analytic/cases_surfaces.py (V = 2A, area 2A + 2P,
centroid by moments). Recipes gain boundary_surface, thicken and remove.

* refactor: boundary surfaces, review cleanups

Project onto the face once per derivative evaluation (the frame is
passed to natural() and reused by scale()), keep each track's
finite-difference step instead of rescanning its table, export the
kernel's edge-pick and chain caps and the default station count for
the engine, doc and dialog to share, map TooLarge spline errors to
KernelError::TooLarge, reuse the engine's operation parser, and skip
the dialog's sketch lookup when the picks are no loop.

bherbruckandClaude Opus 5.5 ccd0b5aab8 Robustness goldens: seeds 13, 71 and 94 build as main builds them, not as #853's branch did (#1929)
#853 recorded seeds 13, 71 and 94 with the face and edge counts its own branch built
(40/101, 19/50, 27/63). With main's kernel they still build as they did before #853
(41/103, 20/52, 26/61), so every full goldens run has failed since it landed. This
records them again; #853's seed 20 change and the other 93 seeds are unchanged.

jyvikoandClaude Opus 5.5 8390a31531 Robustness goldens: seed 55 builds a valid body since #1670 and #1753
Main's CI has failed since 14:47 on `robustness_goldens::all_3`: seed 55 (a
filleted box cut by spheres and patterned) used to end with an invalid body and
now passes the validity check, and its volume moved by 1.3e-5 relative.

The outcome changed between 2ae21143 (main's last green run) and 7f9074d6,
where the kernel meshing change is #1670 (twisted ruled faces divided to the
chord tolerance). The volume changed between 8a055afd and 31b2ddc0, where
#1753 changed truck-meshalgo's triangulation (the faces of an edge share its
points exactly). The kernel's validity and volume checks measure those meshes.
Pull requests run every 8th seed, so only main's full run saw seed 55.

Only seed 55 is recorded, with the values main's CI printed on Linux.

6ad391fd75 Chamfer: refuse a result that grows a convex edge's part (#1428)
* 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.

Co-Authored-By: Claude Opus 5.5 <[email protected]>

* 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.

Co-Authored-By: Claude Opus 5.5 <[email protected]>

* 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.

Giovanniandgvocale faeeff1c64 Blends: a curved seam where the edge chain runs on holds the contact on itself (#1291)
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.

* Action matrix regressions of #1255: knuckle rounds, thin holes, a 45° flange hole, an axis after an edit

- Curve blends: past the end of a curved edge the run of sections along the end
  tangent wrapped round the ring of centres; it is shortened while it still
  crosses the end face (the hinge knuckle's cap rounds at 0.728 mm).
- Boolean retry guard: each body's volume is measured finer than its smallest
  radius, and a volume out of bounds is measured again ten times finer before
  it refuses (a 0.133 mm drill measured -30272 mm³; a plastic part's coarse
  mesh was off by more than the slack).
- Sheet metal: a drill cap's certificate allows the evaluation noise its fitted
  tilt shows (a hole square to a 45° flange).
- Construction geometry on a named face uses the face found by name, not a
  second pick at its nearest point (an axis through a corner round after a
  parameter moved it).

* Retry guard: measure the target, tool and result at one tolerance

Measured at different tolerances, the chords' error on the faces they share
didn't cancel: a blind hole in a long D-profile bar measured 20 mm³ more than
the bar.

bherbruckandClaude Opus 5.5 d73cd8a177 Robustness goldens: record seed 13 after #1164 (#1268)
#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.

* Action matrix: nightly shards cut by measured cost, heavy designs in slices, and a determinism check

The full matrix ran as four fixed quarters of the corpus and two of them hit the 60-minute
job limit. Now action_matrix_shard runs shard k of n (ACTION_MATRIX_SHARD=k/n), planned from
tests/action_matrix/costs.json: designs that take more than five minutes are split into slices,
and the pieces go largest first to the least loaded shard. The nightly runs 12 shards and uploads
each one's outcomes and timings; cargo xtask action-matrix --from DIR --bless records them in the
baseline and costs.json without running the matrix again. action_matrix_determinism runs a sample
twice and lists any action whose outcome changed.

Co-Authored-By: Claude Opus 5.5 <[email protected]>

* Action matrix: baseline and costs from a full run on main, 16 shards, timeouts listed

The baseline is regenerated from the 10 shards' results of a full run on 01b1b705
(cargo xtask action-matrix --from DIR --bless): 8 new designs, 302 actions that pass now,
names that changed, and 40 actions that passed before and fail now, each listed in #1255
(22 fillets refused since #949, 4 hinge blends since #1101, 9 on the loft cut, 5 single).
costs.json now holds every design's measured time, and the nightly runs 16 shards of about
17 minutes. An action that passes in the baseline and times out is listed but not judged,
and stays passing when blessed: two runs of the same build differed only on 10 actions that
took 50-84 s against the 90 s limit.

* Action matrix: slice heavy designs by a hash of each action's name

Slicing by index gave some slices only fillets on oracle 41 (28 slices, a multiple of the
actions per edge), three times the planned time; two shards ran past their limit.

32d3cf6877 Fillets and chamfers meeting at corners on curved faces: what #935 leaves (#854)
* 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.

bherbruckandClaude Opus 5.5 18347b3d0d Boolean nudge: no sliver where a tool only touches a round side (#827, seen in #897) (#941)
* 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 #897
Fixes #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.

bherbruckandClaude Opus 5.5 6cb3025b72 Sheet metal: a hole drilled into a rim is a bore its panel keeps (#560) (#955)
A hole drilled along a panel, into its rim, has no place in the flat pattern
as a cut-out, so every such hole was refused. It is now kept as a bore of that
panel, in flat coordinates, and cut only from that panel's material when the
folded part and its flat pattern are built, so the sheet still unfolds and
folds back with it. A hole that would run into a bend, or cross a panel at an
angle, is still refused. The flat pattern lists the bores.

The action matrix worker takes ACTION_MATRIX_ONLY (just these actions) and
ACTION_MATRIX_UNFOLD (unfold and refold every sheet after each action) for
rechecking one group by hand.

* 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

body is still one closed valid solid. Failing cases are listed in tests/hole_matrix/known_failures.txt

* 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.

bherbruckandClaude Opus 5.5 813bee8914 Fillet: refuse a result with openings in its surface (#871) (#949)
* Fillet: refuse a result with openings in its surface (#871)

A fillet on #871's part (radius 1 on a window's edges and on the sides of a
block 1.26 mm away) came back closed as topology with every face meshing, but
the rounds overlapped and the end faces' boundary loops crossed, so the model
showed holes. The constant-radius fillet now checks its result before taking it:
the body's mesh, welded within a millionth of its size, must have no edge
without as many triangles running the other way along it, except for cracks
within the mesh tolerance where fitted curves meet. A result that fails is
refused, so the corner build gets its try and the radius search treats it as
too large.

Body::open_mesh_edges is the check. Kernel tests cover the #871 part (refused
at radius 1, closed with a round on every edge at 0.5), and an engine test runs
the fillet from the report and leaves the part as it was. All 96 robustness
seeds build the same with and without it.

Fixes #871

Co-Authored-By: Claude Opus 5.5 <[email protected]>

* Check fillets for crossed face boundaries, not free mesh edges

Free edges in the mesh also come from cracks where fitted curves meet (corner
patches, rounds ending on curved edges), so the mesh test refused good fillets.
The check is now on the cause of #871: a planar face whose boundary loops cross
each other or themselves has no inside. Body::crossed_face_loops samples each
planar face's loops within 1/1000 of the size and counts proper crossings
(touching within a millionth doesn't count).

The pyramid apex blend and the loft fillets build again. Ten action-matrix fillets
stay refused, recorded in the baseline: r = 3 on the 2 mm rim of oracle 09's
shelled box (the round runs past the inner wall; the result was 240 mm3 lighter
than any round can make it), and the six seam-edge fillets on oracle 60's bolt
holes, whose boundary jumps across the hole.

bherbruckandClaude Opus 5.5 ea23401710 Sketch on every side wall of one sketch extruded up and down (#957)
* Name a side drawn on several sketch curves by all of them

An extrude named each side wall after the one sketch curve its profile
segment lies on. A wall along two coincident lines (squares drawn edge to
edge) or along collinear lines merged into one profile segment had no
single curve, so it was named from geometry and could not carry a sketch
attachment. One sketch extruded up and down and joined (the logo) refused
a sketch on every one of its side walls.

Such a side is now named by every curve it lies on, in sketch order: the
first is its name, the others aliases. The set is fixed by the sketch, so
the name is exact. The refusal message no longer blames merged faces.

Adds the reported logo design and a synthetic up-and-down join to the
action-matrix designs, and a regression test that sketches and extrudes on
every flat face, fresh and after save and reopen.

Fillets and chamfers ending on a boss's pieced wall or beside it, on a face that runs along its seam twice, and loops the loop blend refuses

- A straight edge whose end meets one curved surface in several faces (a cylinder a join left
  in pieces) ends on that surface: the section is cut where it crosses each seam, which is
  shortened there; where no seam is crossed (the wall missing inside the other body) the
  section lies on the bared surface and the rest of the side edge becomes a seam.
- Two end faces that aren't both planes meeting in lines: each face takes the section's points
  on it, cut where it crosses the edge between them. Not where an end face runs on smoothly
  from a side (an earlier round): the corner build takes those.
- Face boundaries close over several connector edges.
- A face on a periodic surface running along its seam twice (as a STEP file gives it) is
  rebuilt the same way (#691).
- A curved chain ending square on a face that runs on past its side extends that face's seam.
- A smooth chain stops before an edge between faces that meet smoothly.
- A loop the loop blend refuses for its shape is blended edge by edge; refusals about its size
  stand.

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.

bherbruckandClaude Opus 5.5 78d9aa0153 Booleans: small tools in large bodies are traced at their own scale (#559) (#946)
A through-all hole's tool is twice the largest body long, and the boolean's tolerances
followed that length: a 6 mm hole through a 920 mm part was traced at nearly 1 mm, wider than
the hole, and the cut came out empty or failed. When every other strategy has failed, the
boolean is now asked again (unshifted, then once shifted) at tolerances scaled to where the
bodies meet: the overlap of their boxes and the thinner operand's thickness. Its result is
checked as the others are and held to the retry guard. It runs last, so whatever an earlier
strategy answered is kept as it was, and only for single-shell operands (bodies in several
pieces are retried a piece at a time, each with this pass of its own).

The sampled shortcut also gave up on a slender tool lying across its box (a long hole drilled at
an angle fills little of it): it now samples past the first 2000 points until enough land
inside, so a tool that misses a body leaves that body as it is. Bodies that had enough samples
in the first 2000 are sampled exactly as before.

Baseline: the 90 actions that newly pass, rechecked one by one with the final build.

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.

truck's face and edge IDs are their addresses, so walking maps keyed by them followed heap layout, and the ribbed lid's side-wall hole passed or failed by chance. The planar boolean's rebuild and glue now take truck's connected components in the shell's order, and the planar boolean's own maps are ordered. Healing's union-find keeps the lesser root and takes a run's ends in order of use. The face classification after an intersection orders each component's faces by the shell first. The lid now builds the same body on every run, with a test that builds it six times in one process. Its 0.5 mm side-wall holes, and one sensor enclosure hole of the same kind, now fail every time and are marked failing in the baseline.

bherbruckandClaude Opus 5.5 1e4387f3ea fix: cuts no longer split walls they don't touch (#670)
A cut built slab by slab (the exact prism boolean) sewed the result from horizontal
slabs and only joins merged the coplanar pieces back. So a floor vent cut through the
Raspberry Pi case split the long wall into strips at the ports' tops and bottoms
(87 faces instead of 79 at 32 mm), and at 24 mm the end opening split the end wall.

- Prism booleans merge coplanar neighbours for every operation (faces only: edges,
  curves and surfaces stay exact), keeping each face's construction source where all
  its pieces share it, Split Face lines and regularization protection. Painted or
  protected operands keep their authored pieces as before.
- The prism history now tells apart a wall's several edges with its caps (a wall
  with openings meets each opening's floor), so cuts beside existing openings keep
  exact history and faces keep their names.
- Tests: the Pi case's faces pinned after every feature at 24, at 24 changed to 32,
  and built at 32 (each outer side one face); random openings and bosses on a
  shelled case never split another side; every corpus design rebuilds a parameter
  edit like a fresh build and reverts exactly.
- Action matrix baseline: demo/pi-case re-blessed (fewer, merged faces; no
  regressions), demo/pi-case-0.8 recorded, and 88 new passes on
  regressions/lid_ribs_flush_with_window.
