An input that crashes or hangs the C++ reference is rejected, decided from
the inputs or the Rust side, never deferred (as for topology.face_p1's
UB-137 trap). The three units whose guards still deferred such inputs now
return Output::rejected from run_cpp, naming the upstream issue:
- offset.offset_geometry_creation: run_cpp follows the Rust script first and
rejects a script that stops at the HANG-26 (FaceuseOffset self-intersection
of a surface of revolution) or HANG-27 (EdgeuseOffset distance bound) op.
The shim's -6 stop stays as a safety net.
- primitive.api_primitives: run_cpp rejects a pyramid whose Rust build
returns find_outer_loops' "index out of range", exactly where upstream reads
past sOutLoops (UB-119). The C++ no longer runs these inputs.
- topology.brep_p7: run_cpp rejects MakeFaceWithCurves with a curve on
surface, 3D curves and no UV curves past its input checks (UB-165), the
shim's -2 predicate with the Rust degeneracy tests.
16, 5 and 3 rejected: exactly the former guard deferrals; no other outcome
changed. Unit notes, upstream-issues and findings updated.

Upstream keeps one cache per surface object and builds its tree lazily: a
cache made during a Boolean operation has no tree, and its continuity arrays
stay empty until a GetTree. GetDomainWithContinuity and LiftCurve read those
arrays without GetTree, so their answer depends on that history (gen0266:
the face caches were made while reading the .smb file).
Surface now carries a cache slot (no cache / cache without tree / cache with
tree) shared by its evaluation copies; the trimmed cache makers honour and
record it, BuildTreeBase marks it built, ComputeUVPoint records the cache its
global fallback makes, and the continuity readers take their cache from
continuity_surface_cache. GetTree users build a missing tree (solve caches,
offset solve contexts, the tracer constructor).
Difftest: the offset_geometry_creation export carries each face surface's
cache state and the runner seeds it; the upstream:cache-history deferral and
OP_LIFT_OFF_DOMAIN are removed (all 4 cases pass). surface.surface_p1 DomCont
gains a cache history and 96 domhist cases (15 fail without the model).

Restore supported concrete face kinds from native input records, preserve owners and NURBS, and validate complete record framing. Add real cylinder/torus fixtures and signed/zero offset cases. Keep the documented revolution self-intersection hang guard separate from importer limitations.
Native baseline: 631/874 passed; follow-up: 713/898 passed, 185 deferred, zero failed. All 631 former passes remain passing; 58 old deferrals and 24 new cases compare successfully at the unchanged tolerance. Six targeted import/guard/parser tests pass.

Review follow-up on the 6 pass->defer LiftCurve cases (#149 at da779c51).
The shared importer brings every SmBSplineSurface subclass in as its B-spline
part, so sm_ExtractIsoCurve ran the B-spline CreateIsoParametricCurve on the
Rust side while the C++ ran the subclass override (gen0683: circle 14021 vs
B-spline 14033).
- shim: Export appends, per B-rep and face, the binary WriteToDB record
(version 33) of a surface that is exactly an SmSurfOfRevolution.
- ffi: split_revolutions parses those records.
- runner: read_revolutions replaces such a face's surface by
SurfOfRevolution::read_from_db of the record (owner kept) and marks it
exact; put_curve exports every SmBSplineCurve kind (type + NURB) as the
fixture's put_curve does; the non-local FaceuseOffset HANG-26 stop is keyed
on the face's subclass type, as the shim's, not on exactness.
offset.offset_geometry_creation: 861 cases, 552 pass (was 542), 0 fail, 309
deferred. 10 harness:analytic-geometry-export deferrals pass: the revolution
lifts gen0009, gen0148, gen0520, gen0683 and gen0070, gen0178, gen0187,
gen0597, gen0698, gen0767. 9 relabel to intersect.surface_drop_curve.
gen0119 / gen0707 (SmSurfOfExtrusion) and gen0376 (SmSphere) stay deferred:
the Rust SurfaceKind has no extrusion or sphere variant. No other case changed.
fmt, clippy x2 clean; solidcore-ffi tests 95 ok.

- VertexOffset walks no loops (IsLaminaVertex is GetEdges + IsLamina): the shim
and runner drop the all-loop-edge-use guard for it and keep its per-edge checks,
so wire / network vertices are compared (8 generated cases now compare its
result; 4 new built-in cases on the wire network and a single wire).
- HaveTangentGaps accepts n = 0 (upstream evaluates once at 0/0); new case
cone_have_tangent_gaps_no_samples.
- OffsetBrep / OffsetExecutive docs: the per-method contract a library-side
adapter must keep (the difftest runner's choices).
- Module header: the stale sSolutions2[0] read is in ExtendTrimEdges (cpp:1610)
and defined upstream; unreachable, refused by the port.
866 cases: 433 pass (430 compared + 3 guard agreements), 0 fail, 433 deferred;
perturb 433/433; FUZZ-PASS 2000; seeds 4066/2119/0/1947; green 208, failed=0;
valgrind clean on the 13 changed cases.

- GetCreateExtendedSurface: OffsetExecutive<O> gains get_create_extended_surface
(&mut executive); the runner's Exec wraps #175's OffsetExecutive (handles folded
into its typed ids) and seeds its extension cache with each face/store surface
mapped to itself before every op, as the shim seeds m_vSurfExtSurf.
OffsetExecutive::insert_extended_surface added for that seeding (noted in
offset.offset_executive_p1's notes).
- NormalizedEvaluate / CreateUVTrimCurve: OffsetBrep methods over
topology::edgeuse::p3 (exact upstream arguments at every call site).
- #117's &mut Brep / kernel signatures: the seam, tangent-sector and
convex-sector OffsetBrep methods and have_tangent_gaps take the B-rep mutably.
- HANG-17 now refers to main's HANG-16.
Counts and notes follow once the remaining flips are settled.

- CreateOffsetSurface dispatches through Surface::create_offset_surface.
- SetAllowExtension(FALSE) on the analytic offset copies.
- The offset-surface rail builds the SmOffsetSurface and defers at
SmCrvOnSurf (UNPORTED(curve.crv_on_surf), main's label).
- Hang guards renamed HANG-21/22 -> HANG-26/27 (main's #62 took 21/22);
the HANG-27 bound is chosen for the fuzz time budget, not the
termination boundary (~1e250).

- Code behind stubs ported as upstream runs it: HaveTangentGaps' and
TrimExtendedEdge's unchecked Evaluate/EvaluateNormal/NormalizedEvaluate/
ClosestPoint statuses, ExtendTrimEdges' pOtherUVCurve (passed on and trimmed
in place without an other extended surface), the mate read inside the &&.
- Every stub carries all upstream arguments (literals, header defaults, the
kernel and the B-rep / executive it is called on).
- Shim status -6 stops a script where the Rust defers anyway: non-local
FaceuseOffset on a face imported as its B-spline part (HANG-21, offset
self-intersection of an SmSurfOfRevolution), EdgeuseOffset with
|dist| > 1e6 (HANG-22, bound for the fuzz time budget); runner mirrors.
- Runner surface encoder refuses empty knot vectors (fuzz panic).
- rustfmt on the include!-ed runner/FFI/importer files (lesson 25).
861/327/0/534 unchanged, SENSITIVE 327/327.

M1: FaceuseOffset dispatches CreateOffsetSurface on the surface kind (plane,
surface of revolution, B-spline overrides, else the base) and passes
m_dThisApproxTol3d/10; plane faces are offset instead of deferring.
M2: the SM_CAST_PTR(SmBSplineCurve, ..) edge curves keep their kind, so IsArc,
IsLine, IsClosed, CalculateBoundingBox, Trim, Copy and DropPoint take the
kind's override; only new SmBSplineCurve(*p) and the static B-spline routines
see the NURB part. create_sphere_from_arcs takes &[Curve].
M3: CreateSphereFromArcs' Unported propagates.
M4: one shared trim interval per Trim sequence (knot snaps reach the next trim).
M5: the hang guards are gone; the shim seeds m_vSurfExtSurf before every op so
CreateExtendedSurface never runs in the C++ while the Rust defers at the same
call. HANG-19 withdrawn in favour of PR #175's HANG-16; HANG-17 moved to Hang.
M6: the rail evaluations use bNonZeroTangents = FALSE.
M7: temporaries the solver compares (the extended UV curve, the torus arc) go
to the store so their solutions name an object; --seeds 4000 is clean.
S1: UNDEFINED_UPSTREAM marks the module's own null dereferences; ignore_soft
swallows everything else; the runner reports it as -2, never as 1007.
S2-S3: short-circuit IsArc; null extensions are undefined; ExtendTrimEdges takes
an Option offset edge use; the local creation reads the face surface only
under m_bMakeAnalytics.
S4: nurbs.b_spline_surface_p2 fixture three_arcs_about_two_centres (WR-103,
worded as reproduced). S5: the trait loses tangency_tol_degrees, offset_edgeuse
is "exactly one", pairs are many-to-many, VertexOffset -> VertexOffsetGeometry
(#175 reconciliation in COORD.md). S6: surface outputs carry their NURB.
861 cases, 327 pass, 0 fail, 534 deferred, 0 both-errored; SENSITIVE 327/327;
--seeds 4000: 4061/1599/0/2462; b_spline_surface_p2 764/759/0/5; green-par 198.

Hang guards: HANG-19 (negative offset distance makes CreateExtendedSurface's
doubling loop unbounded) as an exact dist < 0 term beside the measured closed-face
proxy for HANG-17. Local pairs name store surfaces only (a face's own surface
was deleted by the analytic copy and double-freed: three segfaults), resolved
at each local op. Output rule on both sides: out-parameters after a success
status only, existing-topology states after every status. A library
InvalidInput maps to upstream's 1007. UV trim curves of every B-spline kind
(SM_CAST_PTR), the ruled-plane fallback for any non-deferral failure, the
original arc kept across the plane tests of VertexOffset, and WR-103 in
nurbs.b_spline_surface_p2 (rOrigin aliases sRefFrame). MAX_INDEX 4096.
