compare() recursed into list values passing the negated comparison through,
so != meant "at least one item differs" and both = and != matched the same
elements on any multi-valued property (e.g. an enumerated property with two
values selected). Strip the negation for the per-item comparison and negate
the aggregate instead, so != means "no item equals" and stays the complement
of =. The same applies to !*=.

Per aothms's review comment: this file's schema was already changed
independently on v0.8.0 since this branch was created, so this PR's own
edit conflicts with it. Reverting to the current upstream version of the
fixture; the bsdd.py rate-limiting fix is untouched.
replace_attribute() rewrites references inside aggregate attributes via
element.walk(), but never checked whether the replacement value was
already present elsewhere in the same aggregate. For an EXPRESS SET
(e.g. IfcProject.RepresentationContexts, IfcRelAggregates.RelatedObjects)
this can leave the same reference listed twice, which is invalid IFC.
LIST and BAG aggregates legitimately allow duplicates, so a blanket dedup
would be wrong; only SET-typed attributes are deduplicated, determined at
runtime from the schema declaration (IfcOpenShell#8706 review comment).
The SET/LIST/BAG check is cached per (schema, class, attribute index), and
the dedup pass itself only runs when a cheap linear pre-check finds the
replacement value already present in the aggregate, so the common case
(no duplicate produced) pays only that pre-check, not a hash-set rebuild.
Benchmarked against a 23MB (431k entities) and a 104MB (2.4M entities) IFC
model against a large SET attribute: worst case adds well under 1ms per
call; the realistic case (merging duplicate contexts, matching the PR
#8706 scenario) shows no measurable regression.
Fixes the root cause flagged in IfcOpenShell#8706 (Moult), obviating the
need for MergeDuplicateContexts' own manual aggregate-dedup pass for that
scenario.

copy_cost_item appends the copy to the inverse relationships of the
original cost item, which for a root cost item includes the source
schedule's IfcRelAssignsToControl. copy_cost_schedule then assigned that
same cost item to the new schedule as well, so the copies showed up in
both schedules and deleting them from one removed them from the other.
Unassign the copy from the source schedule before assigning it to the
new one.

Two related bugs in read_from_stream's reference-resolution
loop, both reachable from malformed input:
- has_attribute_value<IfcBaseClass*> only checks the stored
slot's type, not that it's non-null (e.g. an explicit $
value), so the following get_attribute_value() call could
return null and inst->declaration() crashed on it.
- byid_[ref] default-inserts (and returns) a null pointer
when the owning instance id isn't present, which was then
dereferenced unconditionally via ->data().
Added regression tests using the two minimized crash inputs
that found these.

The fixture declared FILE_SCHEMA(('IFC2X3')) but used
IFCPROPERTYSETDEFINITIONSET(...), a defined type that only exists in
IFC4+ (confirmed absent from the generated Ifc2x3-schema.cpp/
Ifc2x3-definitions.h, present in the IFC4 equivalents). The file's own
FILE_NAME record ('Column_4x3.ifc') suggests it was originally
exported as IFC4X3 and the schema tag was later miscopied to IFC2X3.
Traced with an instrumented parser build: on encountering the
unrecognized keyword, declaration_by_name() correctly throws
"Entity with name 'IFCPROPERTYSETDEFINITIONSET' not found in schema
'IFC2X3'", caught by the existing IfcException handler in
in_memory_file_storage::load(). The parser then falls back to parsing
the trailing (#136,#138) as a plain nested SET rather than the typed
value, so RelatingPropertyDefinition ends up as a bare tuple instead
of an IfcPropertySetDefinitionSet-wrapped value with .is_a(). This is
correct, expected behavior for content that doesn't match its
declared schema - not a parser bug. Fixing the header to IFC4 (which
does declare the type) resolves test_stream, test_file, and test_rocks
in test_streaming_rocksdb_and_simpletyperefs.py.

Expose the Euler rotation of an element's placement in degrees through
get_element_value, alongside the existing x/y/z and easting/northing/
elevation keys. This makes element rotation exportable through ifccsv,
e.g. for placing oriented symbols in GIS.
Adopts the approach agreed in the review of the stale PR #6272 by
@TZwielehner: reuse util.shape_builder.np_matrix_to_euler and do the
degree conversion inside get_element_value.

The guard that avoids re-assigning the same object to the same resource
tested is_a("IfclRelAssignsToResource") (stray "l"), so it never matched.
A repeat assignment therefore fell through and appended the related object
to RelatedObjects a second time. Corrected to "IfcRelAssignsToResource".

FormatTransformer.round() called Decimal() directly on the input value,
which raises decimal.InvalidOperation when the value is a non-numeric
string (a text property, or a value carrying a unit suffix like "12.5 m").
In a spreadsheet export this crashed the entire operation as soon as one
element carried such a value.
Now round() catches InvalidOperation and returns the value unchanged, the
same graceful-fallback convention used by add(). Numeric rounding is
unaffected.

The filter_elements selector grammar had no way to comment out part of a
query, so users had to delete and retype text to temporarily toggle a
facet. Add a /* ... */ block comment terminal that is ignored by the
lexer, and tolerate a trailing "+" so that commenting out the final
operand (e.g. "IfcWall + /* IfcSlab */") parses cleanly. Comments may
span multiple lines; a /* sequence inside a quoted string is not treated
as a comment. Only the filter grammar is affected, not get_element or
format which use "/" for regex and division.
Adds a regression test and documents the syntax.

poe ty's sequence only reaches ty-ios once ty-bonsai passes, so these
never surfaced until now:
- util/alignment.py: drop the stale `include_referent=False` kwarg from
add_zero_length_segment() - that parameter was removed from the function's
signature in 45ea5eb07 but this caller in a different file was missed,
leaving a latent TypeError if this code path is ever exercised.
- ifcopenshell_wrapper.pyi: add the optional trailing `logger` parameter to
parse_ifcxml/open/construct_iterator*, matching the real SWIG signatures
in src/ifcwrap/*.i (all declare `Logger& logger = Logger::Root()`) that
the hand-maintained stub never picked up.
- ifcopenshell/__init__.py: remove a stale `ty: ignore[unknown-argument]`
comment that ty confirms is no longer suppressing anything.
- assign_cost_item_quantity.py: OPERATORS mixes 2-arg binary operators with
the 1-arg `operator.neg` (for ast.USub), but FormulaEvaluator has no
visit_UnaryOp so USub can never reach this lookup via visit_BinOp.
Suppressed at the call site rather than touching the dict, since this
looks like scaffolding for unary-minus support rather than dead code.
- Explicit submodule imports (ifcopenshell.geom / api.alignment / util.unit
/ api.aggregate / api.context / api.spatial) added where accessed but
only reachable by accident of import order.
IfcGeometricRepresentationContext.Precision is typed as a plain IfcReal
but is interpreted in the project length unit, so the IfcLengthMeasure
traversal in convert_file_length_units never touched it. A model
converted from mm to m kept a Precision of e.g. 0.01 (fine in mm, huge
in m), which breaks downstream geometry interpretation such as
IfcConvert boolean cleanup.
Subcontexts derive Precision from their parent, so only root contexts
are scaled.

get_info_2 advertises the same signature as get_info but raised a bare
AssertionError for anything the C++ fast path does not implement --
including its own default arguments (recursive=False).
Use the fast path when recursive=True, return_type=dict and ignore=()
hold, and delegate to the pure Python get_info otherwise. As noted in
the issue, without recursion there is no meaningful performance gain to
lose by delegating.

test_memusage_partial_open was silently skipped in CI (psutil was
never installed there). Add psutil so it actually runs, and run the
RSS measurement in a subprocess so the fixture file isn't already in
the page cache from earlier tests, which was making both deltas read
as zero.

Adds the IFC-library primitives the ifcpatch Migrate recipe needs for a
defensive IFC4 / IFC4X3 -> IFC2X3 downgrade without each caller
reinventing the wheel.
In ifcopenshell.util.schema:
- Migrator(fallback_element_to_proxy=False) opt-in: when True, IFC4-only
IfcElement subclasses (IfcLamp, IfcPipeSegment, IfcGeographicElement,
...) migrate to IfcBuildingElementProxy instead of raising. Default
preserves the strict failure-on-unmappable contract for existing
callers (classification API, etc.).
- geometry_classes_introduced_after(target, source) derives the
IfcRepresentationItem subclasses present in `source` but absent in
`target` directly from the loaded schemas. Cached per pair. Replaces
hand-curated class lists that drift with each IFC update.
ifc4_only_geometry_classes() retained as an alias.
- generate_default_value synthesises a unit IfcAxis2Placement2D /
IfcAxis2Placement3D when downgrading entities whose Position became
required in the target schema (IfcIShapeProfileDef and friends in
IFC2X3).
- Enum-mismatch detection upgraded from string-matched RuntimeError to a
structural check via ifcopenshell.util.attribute.get_enum_items so
upgrade paths still surface real bugs loudly.
In ifcopenshell.util.shape_builder:
- polygonal_face_set_to_faceted_brep converts IfcPolygonalFaceSet /
IfcTriangulatedFaceSet (IFC4-only) directly to IfcFacetedBrep,
preserving topology including IfcIndexedPolygonalFaceWithVoids inner
bounds. Validates inputs at the boundary.
- arc_to_polyline_points approximates a circular arc through three
points with a chord polyline of configurable subdivisions. Tolerates
floating-point noise on planar Z. Raises on non-planar or invalid
inputs.
Test coverage: 47 unit tests across schema + shape_builder lanes
covering each helper directly (no transitive-only coverage), including
regression pins for the IFC4X3-prefix ordering invariant in
get_fallback_schema and the strict-default Migrator contract.

add_railing_representation now factors into two parts:
* compute_wall_mounted_handrail_geometry returns a pure-geometry
WallMountedHandrailGeometry dataclass (handrail polyline + support
list + terminal caps), no IFC mutation.
* add_railing_representation wraps that dataclass into an
IfcShapeRepresentation as before.
Downstream consumers that want the same math without round-tripping
through an IFC file (Blender gizmo previews, viewport drafts) now
drive compute_X directly. Future add_X_representation work in the
geometry API is encouraged to follow the same shape — a sibling
compute_X function + thin IFC wrapper.
The railing_type parameter is dropped from the signature — only
WALL_MOUNTED_HANDRAIL was ever supported, so the kwarg was dead.
The Bonsai railing-modifier caller is updated in the same commit
to stop passing it; without that update Bonsai's
finish_editing_railing_path raises TypeError on the first edit.
RailingSupport and WallMountedHandrailGeometry use @dataclass(slots=True)
— they're constructed N-per-cap during arc sampling, so the per-instance
overhead matters.
Public symbols (RailingSupport, TERMINAL_TYPE,
WallMountedHandrailGeometry, compute_wall_mounted_handrail_geometry,
