Part of #771 and #772. solid.sweep and surface.sweep take orientation (perpendicular, parallel or a direction), twist (up to 4 turns) and end scale (0.01 to 100), applied about the profile's normal through the path's start; default options run the old sweep, so existing sweeps are unchanged. New fields are optional, left out when unset and noted under format 21; twist and scale are model parameters. Both sweep dialogs get Orientation, Twist and End Scale rows; labels in every catalog. Checked on main + this branch: cargo check --workspace, kernel/engine/UI sweep tests, the doc suite and the robustness goldens.
A tapered extrude now offsets spline and conic curves as well as lines and arcs, so sketch text and any other profile can take a taper, and the join of tapered letters onto a face finds its boolean result.
* 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.

Each section now starts at the rotation whose vertices line up best with the lead section's, vertex for vertex, instead of at the one vertex closest in direction to the lead's first. Fixes the twisted loft of matching non-convex sections; regression test loft_pairs_the_vertices_of_matching_non_convex_sections.
Each wall of a surface built from sketch curves (Surface Extrude, Revolve, Sweep and Loft) is now named after the curve it comes from, exactly rather than from geometry, so references to those faces survive edits.
Surface Loft lofts open or closed curve chains, one section per sketch in pick order, into surface bodies. Adds the SurfaceLoft feature (format 18 note), the surface.loft command, a dialog with Edit Feature support, and kernel and engine tests.
Part of #757.
Surface Sweep carries open curves and closed profile boundaries along a sketch path into surface bodies, with smooth walls along curved point paths. Adds the SurfaceSweep feature (format 18 note), the surface.sweep command, a dialog with Edit Feature support, and kernel and engine tests.
Part of #757.
surface.extrude sweeps open curve chains and profile boundaries along the sketch normal into a surface body (walls only, no caps). Saved under format 17.

Tapered extrudes accept profiles that mix lines and tangent arcs (slots, D-profiles, rounded rectangles): each arc keeps its centre and angles and its radius moves with the taper, so its side stays an exact cone; lines are offset and mitred. An arc meeting another edge at a corner is still refused. Un-ignores the #546 regression test. Fixes#546.

Profiles revolved together merge into one region that keeps a vertex where
each shared edge met the axis. With the axis edge in several pieces the loop
skipped the builders for a profile with an edge on the axis, and the generic
sweep turned each piece into a degenerate face that booleans failed on.
Runs of collinear axis lines are merged into one first.
Fixes#487

A full revolve of a profile with more than one edge on the axis (a spherical shell's half ring:
both radial lines lie on it) took the generic sweep, built in place. Truck tessellates the
degenerate faces those edges sweep reliably only with the axis through the world origin, so on a
sketch plane off it the body measured about a third too large (a shell from r 18.5 to 40, 10 mm
above XY: 324 339 mm³ instead of 241 561), and booleans with it failed or removed the wrong side.
Such profiles are now swept about an axis through the origin and translated into place, as
revolve_touching_axis already does for profiles with one edge on the axis.

One numbered loop type (crate::numbered) carries each segment's profile
numbers through orientation, snapping, circle re-seaming, re-sampling and
rotation; every builder orients its regions through it once. Builders that
make their own side faces pair each face with its provenance as it is made
(ruled walls by the wire edges each face holds, smooth lofts, coils and path
sweeps by segment), and cap_and_close appends the caps itself. Column
following is kept only for faces truck sweeps internally (rsweep, tsweep
along paths, cones, where an apex vertex stays put). Extrude derives face
sources and history in one topology pass. One attach entry point takes
operands with their edges already indexed.
Geometry, face order, face sources and recorded origins are unchanged.

Extrude, revolve (partial and full turn), tapered extrude, loft (incl. to a
point), sweep, path sweep, coil, primitives, lip, emboss and thicken attach
the exact history of the bodies they build: each face's profile segment, cap
or operand face, and each edge's operand edge, recorded by topology identity
inside the building call. Nothing is sampled; a body whose faces do not follow
the expected construction carries no history. Face sources are unchanged.

Record ownership transfers in the timeline so earlier Join/Cut membership,
world placement, machining data and styles survive component moves, edits,
independent copying, undo and reopening. Preserve pending positions in history
snapshots and keep constructor transfers ordered during feature redefinition.
Retain shallow sheet pockets and exact planar intersection islands through
unfold/refold, with depth-aware flat previews and DXF export. Store explicit
3D wire coordinate spaces and migrate known legacy provenance without moving
saved points or analytic fits.
Infer unique eligible cylindrical Emboss targets, align Revolve manipulators
with actual extent geometry, and discard obsolete preview errors after input
correction. Certify constructed and immutable imported face styles using exact
source metadata while preserving legacy face names. Upgrade designs to format10
with bounded validation and geometry-preserving legacy migration.
kernel::sweep swept segment by segment: a line translates the profile along it, an arc turns it. At a sharp corner the next line runs within the plane the profile has reached, so the profile slid sideways in its own plane and the walls folded into an inside-out, zero-volume shell. Paths whose direction changes at a joint (more than 1e-3 rad) are now swept as a polyline by sweep_path, which mitres the corners; arcs become points within 0.01 mm. Smooth paths (lines and tangent arcs) are swept as before. Pipe uses the same path.
Tests: sweep_round_a_sharp_corner_is_mitred sweeps a 2 x 2 square along an L of two 10 mm lines and checks the volume, 80 mm3 (fails on main).

- solvecraft-cli fuzz / fuzz-one: seeded random modelling sessions (boxes, extruded profiles with arcs, revolves; joins and cuts of boxes, cylinders and spheres, fillets, chamfers, shells, holes, patterns) on a grid that makes coincident faces and tangencies common, every step checked (command ok, every body a sound solid via the new Body::validity, volume moving the right way), plus the boolean volume identity on random primitives; one process per seed with a time limit; failures minimised to scripts
- shell/offset: corners where a curved face meets another at an angle are refined onto the moved surfaces (Newton); edges that are neither lines nor arcs are rebuilt through their moved points; one shell per piece; faces that would cross say so (not supported yet) instead of leaving a cavity inside out; flat revolved faces count as planes; the unhealed body is tried when the healed one fails
- cylinders start their seams at an odd angle (grid-aligned seams broke booleans along them)
- partial revolves of profiles touching the axis build no zero-area face on the axis
- booleans on bodies in several pieces retry a piece at a time
- regression tests for each, and a fixed set of seeds in cargo test

The kernel moved from monstertruck to truck: truck's booleans handle blind
holes, pockets and bosses that monstertruck's did not (see the ADR). Fillets
and chamfers on straight convex edges between planar faces are our own exact
local B-rep operation. The document holds parameters with unit-aware
expressions and a timeline that re-evaluates incrementally.
