The kernel's Continuity moves out of bridge.rs into continuity_order.rs and gains G4. One
table holds each order's command word (g0-g4), its code (G0-G4, for tips and messages) and
the message ids of its label and hover text. Construction says which orders the patch,
bridge, network, match and sketch blend curve build today; Continuity::built_by is the one
refusal every command and kernel entry point uses. A design may now save g4 (format note).

The analysis sliced the display mesh with planes: faceted, approximate, and
broken at triangle seams and trims; the window drew it as a 2D overlay without
depth while the tool was active. Now one kernel routine (kernel::iso) clips a
surface's u = const or v = const line to a face's pcurve loops; the curve through
a point (sketch projection) and the analysis grid (count each way, evenly across
the face's extent) both use it. The loop polygon follows the loop's order (a
pcurve the loop runs against is walked backwards), which the inside test got
wrong before, and closes over vertex-loop poles.
ModelBody caches the lines per face, count and display quality. The session
keeps the picked faces as view state (inspect.isocurve add/clear, hostile counts
refused); the viewport, ui.render and snapshots draw them depth tested in the
accent colour. Curvature combs on faces follow the same exact lines.

New metric tapped holes drill the tap maker's drill (M8 6.8 mm). The Design preference "Metric
tapped holes drill the major diameter less the pitch" (`metric_tap_drill_major_less_pitch`, off
by default) gives them the drill every metric size took before (M8 6.75 mm): the Hole dialog
shows and sends it, and `solid.hole` given a thread and no `diameter` drills it, through the
session as `auto_project` is (kept when a design is opened or started, and across tabs). Unified,
pipe and taper sizes keep their tabulated drills; a given diameter is unchanged. Saved designs
keep the drill they stored either way.

Every tapped hole now drills the tap maker's tabulated drill. ISO metric takes Yamawa YEU23's
drill size column for cutting taps (printed p.704, M coarse; pp.704 to 706, MF fine): M8 drills
6.8 mm and M12 10.3 mm, where the major less the pitch gave 6.75 and 10.25. A custom metric size
the table lacks keeps the major less the pitch. UNC/UNF (Guhring), G, Rp, Rc and NPT (Yamawa)
were tabulated already. The Thread command's suggested hole for a metric size follows.
The Hole dialog's Tap drill diameter is now a field, the tap maker's drill by default, and the
command's `diameter` with a thread is checked the same way: a drill is accepted from the
internal thread's standard minor diameter (or the tap maker's drill where that lies below it:
Rp, Rc, NPT) to 5% over the tap maker's drill. Outside that the command names the range and
why. The field's tooltip gives the drill, the minor diameter and the range. Presets keep a
chosen drill.
A saved design keeps the diameter it stored, so it builds as before, and editing such a hole
keeps its drill: no preference and no format change. Scripts that give a thread without a
diameter drill the new default; ladder 05/007, 11/003 and rig case threads/2115 follow
analytically, and their golden entries are re-measured from runs (tier 05 re-sorted by time).

The Rc and NPT drills were rounded to a drill series from a third-party reproduction of DIN 345
and a fractional/letter inch series cited from memory. They now come from the same tap maker's
catalogue the G and Rp drills do: Yamawa YEU23, printed p.709 (Rc, the maximum straight bored
hole with non-full threads, Rc 1/16 to 4) and p.710 (NPT, the maximum straight bored hole, 1/16
to 3). A size its tables lack (Rc 5 and 6, NPT 3 1/2 to 12) is refused as a tapped hole, naming
the range. The dialog's tooltip keeps the standard's minor diameter where the thread ends.
Rc 1/2 drills 17.6 mm (minor 17.807), 1/2 NPT 17.60 mm (minor 17.473).

An Rc or NPT hole was drilled to the exact minor diameter where the thread ends, a size no shop
stocks. It now takes the largest stocked drill not larger than that: metric drills of the DIN 345
series for Rc (to 100 mm), letter and fractional inch drills by 64ths (to 1 1/2 in, ASME B94.11M)
for NPT; past the series it is bored to the exact value. The Hole dialog's drill shows the inch
size for NPT, and its tooltip the exact standard value. Rc 1/2: 17.807 mm, drilled 17.75 mm;
1/2 NPT: 17.473 mm, drilled 11/16 in (17.4625 mm).

The tapped-hole catalogue takes ISO 7-1's Rc and ASME B1.20.1's NPT internal taper threads,
every size of the tables a modelled thread cuts. Their drill is the internal minor diameter where
the thread ends (the reference plane's minor at the face less the 1 in 16 taper over the useful
or effective thread length), derived from the standards rather than a tap maker's table. An
external R is still no hole's.
A tapped hole's options mirror the thread's: `modeled` cuts its thread into the wall, from the
entry, by the same cut as `solid.thread` (now one function both call), and `ease_out` fades its
inner end out before the bottom (ISO 3508); without it the groove stops square at the thread
depth, clear of a blind hole's bottom. The Hole dialog's Tapped rows add Rc and NPT, Modeled
and the End choice (Square, Fade, Fade Length). The format notes in pending/thread-ends.rs and
pending/pipe-threads.rs record the new keys and sizes.

The thread dialog offers the pipe threads: G (ISO 228-1), Rp (ISO 7-1), R and Rc (ISO 7-1) and
NPT (ASME B1.20.1). Their sizes are listed by designation without a pitch, one start and a hand
of right or left; a size picked for a hole the dialog sized Rc stays Rc.
Rp, ISO 7-1's parallel internal thread an R screws into, is a form of its own (`rp`): the
parallel profile (H = 0.960491 P) at ISO 7-1's gauge diameters, refused on a shaft. Its cut
meets the analytic material of its profile within 1e-5, as G does.
A taper thread takes a chamfered tip: each end's cone is measured from the major diameter the
taper has at that end. Pipe threads are not ISO metric, so they give chamfer_depth.

A thread's start runs off its free end, plain or chamfered; only its inner end fades out
(ease_out) or stops square. The `ease_in` field, the command parameter (refused now, naming
ease_out), the dialog's Ease In row and their docs are removed; `pending/thread-ends.rs`
drops a saved `ease_in` as the design opens. The runout test covers the short, standard and a
sub-turn fade at the inner end.

The free-end test looked for material 1 to 1.5 pitches past the face's end, beyond the first
pitch so that a chamfer the groove runs out through counts as free. A plate thinner than that
(a boss on a 1 mm plate under M10) had none there, so its top was taken for a free end and
the groove's one-pitch overrun cut into the plate (15 mm³ of a 1 mm plate).
An end is now closed when, over the overrun's whole reach, material lies outside the face's
cylinder (inside it, for a hole) at the radii the groove cuts beyond the face: a shoulder,
plate, head or blind bottom, however thin, steps out past the face, while a chamfer, neck,
countersink or counterbore steps the other way. The band test beyond the first pitch stays
for a cylinder that goes on past a split.
The regression test builds the boss as the app does (a rounded plate, a circle sketched on its
top face, extruded with Join) on 6 and 1 mm plates.

Three forms: `bspp` (G, ISO 228-1, 55° parallel), `bspt` (R external, Rc internal, ISO 7-1,
55° taper 1 in 16) and `npt` (ASME B1.20.1, 60° taper 1 in 16). Their sizes are tabulated
from the public sources: ISO 7-1:1978 Table 1 (its gauge-plane diameters are the G sizes)
and NBS Handbook H28 (1957) Table VII.2; tests check every row against the standards' own
relations.
A taper thread starts at its free end with its standard diameter there (external: the gauge
diameter its gauge length in, internal: at the face). Its groove is the screw sweep with the
section moved 1/32 of the axial travel off the axis (the radial law the runouts use, added to
it), its section reaching just past the crest, and the material beyond the major cone (or
inside the minor cone) is cut with it, as a die or tap cuts the crests. An external one runs
its standard length by default.
The volumes are checked against the profile's material fraction integrated over the tapered
radii: G 1/2 to 2e-6, R 1/2, Rc 1/2 and 1/2-14 NPT within 0.2 % of the cut.

`tip` was none|chamfer, chamfer cutting every free end. It is now none|start|both: `start`
chamfers the end the thread starts from, refused when that end is not free (a shoulder, or a
stop inside the face), and `both` every free end as `chamfer` did. The dialog's Tip pick offers
None, Start and Both; `tip: chamfer` in a command names its replacements.
The thread's end options (runouts, tip, chamfer angle and depth) came without a format
change file; `pending/thread-ends.rs` records them and rewrites a saved `tip: chamfer` to
`both`.

ISO 4753's chamfered end bounds the end's diameter by the minor diameter. The default took the
modelled root (the basic d1) for it, so the cone's small circle lay on the root cylinder and
the chamfer ring pinched to nothing wherever the groove reached the end. The default is now
the external minor diameter d3 = d - 1.226869 P of ISO 724, below d1: the cone crosses the
root, each end is a whole disk of d3 inside a whole conical ring. ISO 4753 is for ISO metric
threads; the other forms, whose root is already their design minor, give chamfer_depth.
Ladder 06/017's analytic volume follows (1945.354522563); its golden entry re-measured.

v0.24.0 (format 39) saved a left-hand Thread or tapped Hole as `handedness: "left"`; this
branch replaced main's handedness (#4414) with the thread's `hand`, and features don't refuse
unknown fields, so such a design opened right-handed without a word. The pending format change
thread-hand.rs renames `handedness` to `hand` on Hole and Thread features (a `right` is
dropped, anything else refused).
Tapped holes take `hand` again, right or left (never both, and only with `thread`): the Hole
feature saves it, its thread is cut and annotated that way, solid.hole takes `hand?`, the hole
dialog's tapped rows have the thread dialog's Hand choice (without Both), editing a hole keeps
it, and hole presets save it under v0.24.0's `thread_options.handedness` key, so presets saved
by v0.24.0 recall it.
Test: a format-39 design with a left-hand thread and tapped hole opens left-handed; a hole's
`hand` refuses both and needs a thread.

Code main added since the last rebase reads the placed model, a camera or a scene
as values; on this branch they return Result. Picks and the edit dialogs read the
session's placed model through open_meshing::session_world, as the others do; the
revolve and circular-pattern axes, the model axis of a command and the warming of a
computed edit pass the error on; tests unwrap. A test meshing bodies uses
Body::mesh, the one mesher.

exact screw sweep. Main's #4414 added a second one, `handedness: right|left`, on
Hole and Thread, for the faceted groove this branch replaces. It is taken out: the
field, its pending format change (never released), the hole dialog's direction row,
its hole-preset option, its strings and its tests, which measured the faceted
groove. A tapped hole is right-handed, as before #4414.

A modelled thread never changes the size of the shaft it is on (#1018, #2853): a
shaft thicker than the thread is refused with the size to make it, as
tests/kernel-cases/threads/2705 expects ("this 14.6 mm shaft is too thick for a
modelled M14 thread; make the shaft 14 mm for M14"). This takes out the turn-down
of #4256: `thread_turn`, the fit that let a thicker shaft through, and its tests;
the 9 mm shaft refusing an M8 and the preview's M6 refusal on an 8 mm shaft are
back as they were before it.

The branch's placement change (placing the model returns its error) made
world_state, home_camera, bounds, open_sketch_plane, the scene builders,
to_local and auto_operation return a Result. Main added callers of them
since the branch left it; they now take the error as the branch's own
callers do:
- engine: commands pass it on (`?`); helpers answering yes/no or "found"
(snap points, a face's normal, the DXF export check) answer no for a
model that cannot be placed. Frames keep the session for main's lazy body
frames (#6356) beside the placed model the picks are on; a library apply
maps its targets on that placed model. Before an extract or a link is
replaced, the placed model is taken or the command fails.
- ui: panels, picks, dialogs and previews read the placed model through
open_meshing::session_world (none when it cannot be placed: the viewport
says why); Home and Fit frame nothing then.
- cli: the usage table is main's, with kernel-cases in it (a resolution of
the rig's commit had kept the branch's whole file).
- tests read the Results with unwrap, and main's tests of Body::tessellate
mesh through Body::mesh. Main's test of saved boolean retries goes (the
branch saves none), as does the thread half of its dialog rendering test
(the branch's thread dialog has its own); the tapped hole half stays.
- What no caller uses after the merge goes: a mesh body's span, the metric
thread refusal text, and the revolve's targets-as-shown model (main used
it for the coplanar run-on the branch removed). Main's SolidWorks Y-up
test reads the exporting system's name (the branch's STEP header has no
preprocessor or description fields).

Main gave the Thread feature two things the branch's thread rework (forms,
hands, starts, extents, runouts, tips on ThreadAsk) was written without:
- Tapped holes take catalogue sizes (ISO metric and the catalogued UNC/UNF,
G and Rp sizes): `ThreadAsk::tapped` reads the designation from the tapped
catalogue, names the thread as the catalogue does, and fits a size that is
not metric to the hole drilled for it (its tap drill). The hole feature
asks for its thread this way.
- A modelled external thread on a shaft thicker than it turns the shaft down
to its major diameter first (#4256): main's `thread_turn` makes the ring,
the shaft is cut by it, and the grooves and a chamfered tip are cut at the
turned radius. Such a shaft fits the thread.
ThreadInfo keeps the radius of the face it is on, which main's cosmetic
thread display draws at (0 in a state saved without it).

The branch rebased onto main keeps each of its commits; where both sides
changed the same code, these are the pieces neither side's commit had.
- Cargo: one [features] table in the CLI's manifest (two met in the merge).
- geom: a NURBS surface's `closed` set once in a placed copy (both sides
added it).
- kernel: the whole-face extrude tools (#2040) work around truck's boolean
on truck types, which left the workspace with the SMLib kernel; the
module, its tests and the doc crate's tool and tests go. The display
planner's flat fill (tess/fallback.rs) has no caller with the schema 4
mesher, and the tessellator's seam and uv modules are the branch's. A
body's boundary tolerance from a STEP file belongs to the truck body the
schema 4 record replaced: `with_boundary_tol` goes. `unmeshed_faces`
counts the coarse mesh as the branch does. A loft's section re-split
passes the lead's perimeter shares to main's `resample` (a circle breaks
there when the matched corners do not go round in order). Main's tests of
the mesh-based measure (the SMLib kernel measures exactly) and of the
IGES preprocessor name (no such field on the branch's import record) go.
- doc: a feature result carries no boolean diagnostics on the branch, so
the model cache neither writes nor reads them, and a pattern copy's miss
test runs the intersect as it is. A placed body's worker result is a
Result: a body taken from the previous placement is Ok. A thread's
clipboard remap takes main's arguments, the tapped catalogue names a
metric size by ThreadForm::Metric, and main's tests unwrap the placing
calls that return their error.

Ladder 06/009 had no way to ask for one: "solid.thread has no runout (vanishing thread)
length". With SMLib's smlib_screw_sweep_radial (replay e7acea1):
- smlib: the FFI binding and Brep::screw_sweep_radial, the profile moved off the axis by a
piecewise linear law of the turn; crate test: a tooth moved out 1 mm over three turns has
A 2π (c turns + ∫ offset dt).
- kernel: sweep_helix_radial, sharing sweep_helix's checks (helix_profile).
- doc: `ease_in`, `ease_out` (a length, or ISO 3508's standard 2.5 P or short 1.25 P) fade the
groove over that length, its section moving out of the material as it turns (outward for a
shaft, inward for a nut). ease_in is at the end the thread starts from. The runout lies past
the full-form length: beyond a square stop, before a shoulder up to its clearance; at a free
end inside the face. Runouts longer than the thread are refused. No end gets one by default,
so saved threads keep their geometry.
The cut is the integral over the turn of the clipped section's 2π∫ r dA: engine test (2.5 P
and 1.25 P between two collars) within the sweep's wall tolerance times the runouts' wall area
(0.029 against a 0.036 mm³ bound), ladder 06/009 (004's shaft, a 2 P runout before the

`tip: chamfer` cuts ISO 4753's chamfered end at each free end a modelled external thread
reaches, after the groove, so the last teeth taper into the cone instead of ending in a
ragged first turn: the material outside a cone `chamfer_angle` to the axis (default 45°)
reaching d_f = d - 2 `chamfer_depth` at the face's end (default the external minor diameter,
the largest the standard allows), a revolved ring cut by one boolean per end. Past the end the
ring keeps to the radii the groove's overrun already cuts. An internal thread is refused (its
entry takes the hole's countersink), as is a tip with no free end or on a cosmetic thread.
The cone is axisymmetric and cut after the screw-symmetric groove, so the volume is the stock's
chamfered section with the thread's material fraction: engine test (both ends 45°, and 30°
x 0.5 mm at a shaft's one free end above a collar) within 1e-4, ladder 06/017 (measured

Ladder 06/008 had no way to ask for one: "solid.thread has no start count". `starts: n` (1 to

pitches along), in one boolean with their union. A designation that gives the lead
(M16xPh3P1.5, Tr40x14(P7)) gives the starts, and a `starts` that disagrees is refused. The
helix's self-clearance check and the turn limit use the lead.
Over the same length n grooves of lead nP take the volume of one start of pitch P: engine test

Only the ISO metric 60° thread existed. Forms now (crates/doc/src/thread_forms.rs, values and
sources in docs/threads.md): ISO metric (ISO 68-1), trapezoidal (ISO 2904 design profile, ISO
2902 sizes), general purpose Acme (ASME B1.5), metric buttress 3°/30° (DIN 513), buttress inch
7°/45° (ASME B1.9 basic profile). Each has its groove as a straight-flanked polygon, its standard
sizes (none for ASME buttress), its designations (M10, M16xPh3P1.5, Tr40x14(P7), S20x4,
1/2-10 ACME, 2.5-8 BUTT) and the size that fits a face. The square thread is refused: no current
standard defines it.
`hand: right | left | both`: a left-handed groove is the screw motion about the reversed axis
rising along it; both cuts the two grooves, crossing, in one boolean. `steep_flank` turns a
buttress. The design diameters are checked against the published tables (ISO 2904/DIN 103,
DIN 513 via IS 4696-3); every form's cut against 2π∫ r w(r) dr per turn to 1e-4 in engine tests
and to 1e-4 in ladder 06/011 to 016 (they measure within 5e-7).
FeatureKind::Thread holds every option the command has (form, hand, starts, ease_in, ease_out,
tip, chamfer_angle, chamfer_depth, steep_flank, all defaulted so saved threads load unchanged);
starts, runouts and the chamfered tip are refused as not built yet. suggested_thread_in takes the

A thread of some length ran from "the end of the face nearest the pick", a coin toss for a
pick in the middle (rig 602's 4 mm thread meant for the free bottom end ran at the head end,
cutting 1.17 mm into the hex), and every thread end at a face end got a one-pitch overrun,
which at a shoulder gouged the material past it (ladder 06/004 cut 0.9% of its volume out of
the collar).
- kernel: material_in_ring, the exact intersection of a body with a ring about a cylinder
face's axis, by an SMLib boolean.
- doc: a face end is free when no material lies past it, over the span the groove's one-pitch
overrun reaches beyond its first pitch, within the radii the groove cuts (a cap, a chamfer
the groove runs out through, a counterbore). At a free end the groove runs out as before; at
a closed one (a shoulder, a head, a blind hole's bottom) it stops with its widest part clear
of it; inside the face it stops square.
- doc: a thread of some length starts at the end nearest `from`, else at the face's only free
end, else at the end the pick lies within a third of the face of; a pick in the middle of a
face whose ends are alike is refused, naming `from`. A length as long as the face runs the
whole face. `up_to` a plane or a point's place along the axis. New fields `from`, `up_to`
default to none, so saved threads keep their meaning where it was not a coin toss.
- engine: solid.thread takes extent (full|length|up_to), from and up_to.
- ladder 06/003 (now with `from`), 004 and 007 are graded by volume and centre of mass in
closed form (a square stop inside material removes exactly length/P turns, the section being
symmetric); rig 602's method says why the thread is at the bottom, tolerance 0.02%.

A notch cut into a sheet's base is a cut-out, so the base outline that
edge_at and the edge names read has no edge along it: a flange picked on
the notch's bottom edge took the name of the nearest outline edge (the
plate's far edge) and was built on the stretch of it the notch left. A
pick nearer a notch's edge than any outline edge now names no edge, and

edge of the outline. The edge of a hole inside the base is refused.

bend modelled R 2 was rebuilt bent R 2.5, losing 8.58 mm3 (2659.911
against 2668.496), and its gap and reliefs followed 2.5 mm too. The rule
is now evaluated for the sheet's thickness (Document::rule_values_at):
in the conversion once the shell's thickness is known, for a converted
plate, and for the flanges, hems and folds added to an existing sheet.

The countersink's cone started 1% of the drilled body's size above the
entry face, widening on to rc + top tan(half) there, so above the face
it cut beyond the countersink's rim: a wall 0.15 mm from the rim was
notched (#5041, 12 faces instead of 10). The tool is now one revolved
profile: the cone from its rim on the face to just inside the bore, and
above the face the rim's own cylinder, as the bore's cylinder runs on
above it. The cone stays the profile's first segment (csink:side:0).

solid.shell refused an empty face list ("select 1…1000 faces"), and the
shell feature found its body from the first face picked. SMLib shells with no
face opened (the void sealed inside, its own shell): the command now takes
`faces: []`, the feature shells the one body there is or the one named
(`body`), and an outside or both-ways shell pushes no open face out of the
cavity. Rig shell/4009 declares the void's shell (`shells: 2`), as its method
says.

fillet_max bisected the radius down on any error of a candidate fillet,
not only KernelError::TooLarge, and fillet_max_each fell back to one
radius for all on any error of a group or of the combined fillet. A
kernel failure at the radius asked for (or at any candidate) came back
as a smaller radius reported as "the largest that fits".
fillet_max and fillet_max_each now return Result<Option<..>>: only
TooLarge narrows the search or falls back to one radius, and any other
error is passed on. Ok(None) is still "no radius fits". The doc's
FilletFit::Reduce passes the error on. The test of a point with no edge
near it now expects the fillet's own error, not "no radius".

With touching: separate (the default) a join groups the joined body's
pieces by face contact. The groups that hold the material of the body
before the feature stay in it (each unless it touches one already kept;
the first group where the lineage doesn't say), and so do the groups that
touch nothing: a virtual grouping later operations take as one body. Every
other group that touches another along an edge or at a point becomes a
body of its own, and the feature's notice says so. The joined body keeps
its name and never holds an edge or point contact. A join that only
grouped pieces apart gives no notice, so KeptSeparate::Apart is gone.
one_body still keeps every piece in one body.
SMLib's export copies an edge or vertex that touching solids share once
per solid, so the record never listed those contacts:
Brep::region_contacts now takes such copies (the same curve and interval
between vertices at the same points, a vertex at the same point) as the
edge or vertex they share. A contact SMLib leaves out of the topology (the
3612 spoke tangent to its hub) is found on the exact geometry, the least
distance within the record tolerance, and reported as KeptSeparate::
Touching ("along a line or at a point").
The pending format change join-touching-bodies stays: older designs kept
pieces touching along an edge or at a point in one body too. Its notes say
so, and the reopened legacy emboss still expects touching: one_body.
Tests restored to their form before cc49081df and 733d3bd19: kernel-cases
2896-join-arm-end-near-ring-wall-gap (one body of two shells), 3379, 3455
and 3526 (no touching: one_body); the engine tests of posts joined while
apart (twice), two cubes for interference, a ring with a cylinder, the
buried tab and a_join_adds_only_its_sketch's 0.1 mm gap.
join_meeting_nothing_keeps_the_first_body expects one body and no notice.
The #3378 spoke stays 1 mm inside the hub.
New tests: blocks touching along an edge are split with the along-an-edge
notice; blocks apart stay one body without one; a ring with an arm on its
corner edge and a hub apart gives ring and hub in one body and the arm on
its own (doc); the engine's notice for an edge contact; the record's
contacts of cubes sharing an edge or a vertex (kernel).

A feature's touching parameter says what a join makes of solids that
share no volume and no area: separate (the default) splits the joined
body's pieces that share no face into bodies of their own, named, with
history and lineage, as a cut's pieces are; one_body keeps one body of
several pieces. The state records how the kept-apart pieces met
(KeptSeparate: along an edge, at a point, apart) for the feature's
notice.
Older builds kept every join's pieces in one body: the pending format
change join-touching-bodies gives each joining feature of an older design
touching: one_body, so existing designs keep their bodies.
kernel-cases 2896-join-arm-end-near-ring-wall-gap: the arm meets nothing,
so it now stays a body of its own (body_count 2, one shell each).
kernel-cases that join solids apart to make the body they test ask for
it with touching: one_body: 3379 (the hub joined to the ring before the
spokes reach it), 3455 (64 pegs in one body) and 3526 (a two-lump target
for an intersect).

Edge::curve_interval (and brep::curve_interval for assemble's edges) gives the interval on the
edge's curve itself: a form circle's angles of its ends, its frame turned by the SMLib conversion
so the angle grows along the NURBS. lip and the ruled surfaces read arcs by it; the hull, the
blend tangents, the patch pcurves, point paths, IGES output and the prism runs evaluate on
Edge::parameters. assemble carries an edge's form through.

The edge mirror of a face's NURBS form: Edge::nurbs keeps the NURBS SMLib holds a conic as, and
the edge's interval and its pcurves' parameter are its. Edge::parameters is the curve every
evaluation at a parameter uses; curve says what the edge is. Nothing writes the form yet.

doc: world_state, world_state_reusing, state_in_frame_at, state_in_frame, face_point_state,
face_point_names and construction_state return Result. A body that could not be placed, a
frame that could not be inverted, a sketch plane or thread axis that did not survive the
placement, or a failed placing worker used to leave things where they were without a word;
now the call fails with what could not be placed. is_placement is the one test of an
occurrence's placement (finite, a rotation that does not mirror, a translation within
1e9 mm). Opening a design names every occurrence that fails it; add_occurrence refuses
one; a joint solution that would place an occurrence outside one is not applied and the
joints placing it report it.
engine: Session::world_state returns Result and keeps a failure in its cache as it keeps a
placed model. bounds, home_camera, open_sketch_plane, the scene builders, the world
previews, frames::to_local and auto_operation pass the error on; helpers answering "not
found" take the placed model from their caller. Commands setting a placement check it
(valid_position, exploded view, fastener at a point, STEP insert matrix).
ui: panels, picks and hovers read the session's placed model through
open_meshing::session_world; a model that cannot be placed shows no placed bodies, and the
viewport says why across its bottom. Pictures and the control channel report the error.
cli, mcp: snapshots, renders, benches and the oracle report the error; the kernel-case rig
records it as the case's failure. Tests read the new Results with unwrap.

Extent.corner is optional: unset, each profile preserves curvature where
every curve is a line or an arc and takes the tangent rule where another
curve has a corner, with a note in the feature's warning; a rule the user
gave is kept. draft_corners reports not_exact as the kernel builds (any
free curve in a cornered profile). Builds (release CLI); cases not yet run.

The kernel blends exactly the edges given; the feature's tangent_chain (default true, saved
only when false: pending format note blend-tangent-chain) expands each pick to its tangent
chain (kernel::tangent_chain) before the kernel call. A variable or spline round takes its
edge alone. Scripts and MCP passing one pick get the chain again.

Every SMLib analytic surface is a B-spline surface, and its trims are in that NURBS's
parameters. Face::nurbs keeps that NURBS: the face's domain and pcurves are its (u, v), and
`surface` says what the face is. Face::parameters is the surface every (u, v) evaluation uses.
The SMLib conversion reads and writes it (fork FACE_NURBS_FORM, SMLIB_REV c4483f6); the STEP
writer writes the analytic surface and the face's edges without pcurves.

Extent.corner (preserve_curvature by default, tangent or round), saved
only when not the default (one pending format change), and the
solid.extrude `corner` parameter. draft_corner_options reports what each
rule gives at each corner of a feature's profiles, for a dialog to offer
the others where the chosen one is a poor fit.

extrude_tapered(_between) take a DraftCorner: PreserveCurvature (each wall
continues as itself, a line's plane or an arc's cone, until it meets its
neighbour; SMLib's SM_OC_CURVE_EXTENSION), Tangent (the offsets continued
along their end tangents) or Round (an arc about the corner). A corner
the rule cannot close is refused with its point and why
(solidcraft_smlib::Error::Corner). draft_corners reports, per sharp
corner of a profile, what each rule gives: how far each offset curve runs
on or is trimmed, whether the corner cuts inside the exact offset, or why
the rule refuses it. SMLib pinned at the fork's draft-corners head.

Owner's decision for strips whose rulings turn freely along their edge (a face's
normal along a free-form face, which was refused): the far edge is not the
offset curve but a B-spline the kernel defines, and the strip is exactly the
ruled surface between the edge and it.
The far curve has the edge's own degree, knots and weights (so the ruled NURBS
needs no knot merging); it runs from the strip's start corner to its end corner
(where the rulings at the edge's ends reach); its interior control points are
given (handles) or the least-squares solution of weighted terms, the
construction's parameters: closeness to the rulings' ends at the edge's
Greville abscissae (W_CLOSE), fairness by arc length (W_FAIR), each end leaving
along the chord to the other end (W_TANGENT, one small function), and at a joint
where the chain runs on smoothly with shared sides the first and second
derivatives by arc length matched to the neighbour's (W_JOIN), in one solve
along the chain, an exact neighbour's far edge matched as it is. Exact strips
are unchanged.
ruled_far_handles gives each free strip's default handles; ruled_surface_with
takes moved ones. The Ruled Surface feature saves them as `far` (per chain
edge, null for the default; pending format note ruled-far-handles), and
surface.ruled takes them as `far`.
