The OBJ serializer wrote the normal index into the texture-coordinate slot
of a v/vt/vn face (emitting v/vn/vn), so exported UVs were wrong. Track a
separate texcoord counter and emit the correct vt index.
Per review, the material lookup is left relying on ApplyDefaultMaterials
(default on, and IfcConvert exposes no toggle to disable it) so an unstyled
element is given the default style before triangulation and material_ids
never contain the -1 no-style sentinel, matching how the Collada serializer
already indexes its materials without an ad hoc guard. The earlier
material_id >= 0 guard is therefore removed.
Verified on OCC 7.9.2: a styled box exports its material, an unstyled box
exports the injected DefaultMaterial (valid index, no out-of-bounds) on
both the default and --generate-uvs paths, and the UV path now emits
correct v/vt/vn indices.

- add_stationing_referent.py: black reformat (new drift from v0.8.0).
- update_fallback_position.py: v0.8.0's changes to this file made the
ifcopenshell.util.unit import (added in an earlier commit here) unused;
removed per ruff.
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.
- tool.py: drop the `-> int` annotation on the Parametric interface's
get_geom_generation stub; its `pass` body implicitly returns None, which
ty can't reconcile with the runtime @interface/@abstractmethod rewriting
it never sees statically. Matches the file's other stubs (-> None).
- railing.py: qualify the "BIMRailingProperties" string annotations as
"prop.BIMRailingProperties" on the two functions using it, since the bare
name was never imported into this module's namespace.
- product.py: suppress ty's missing-argument errors on
copy_z_rotation_to_selected's Surveyor.get_z_rotation/set_z_rotation
calls with targeted ty: ignore comments. The function is unused and its
two dependencies were never implemented on the concrete Surveyor tool;
left as-is rather than deleted or implemented.
- gizmos.py: TYPE_CHECKING-guard `import bmesh` for the string-literal
annotation in build_schematic_mesh; suppress the still-unresolved
gizmo_textures import in TexturedQuadGizmoMixin (WIP dependency, not dead
code).
- model/__init__.py: register the `decorator` submodule, which unregister()
already calls (would have raised NameError on addon disable).
- mep.py / tool/model.py: add explicit imports for bonsai.core.geometry and
bonsai.core.model, previously only reachable by accident of import order.
- Test files: add explicit ifcopenshell.api.pset / ifcopenshell.util.element
submodule imports used but not imported.
Convert bare Mock() to Mock(spec=bpy.types.Object) for Blender-object
stand-ins in TestRecalculateWallsWithNewConnections, TestMEPActionGuards,
and TestRecreateAggregateIteratesAllNew so typos on the Blender API
fail loudly instead of silently returning a MagicMock.
Replace the ad-hoc Mock() ConnectionRecord stand-in in
TestRecreateConnectionsZipsPairs with a real ConnectionRecord instance,
which pins field names at construction and catches drift if the
dataclass fields ever get renamed.
IFC entity mocks remain bare Mock() intentionally: entity_instance
attributes are schema-driven at runtime rather than defined statically
on the class, so spec= would refuse the .GlobalId / .HasFillings /
.ConnectedTo attribute writes the tests need.

Rewrite tool.Array.select_only_parent as a thin call to
tool.Blender.select_and_activate_single_object; drop the ad-hoc
per-child deselect loop and the unused parent_element parameter.
Replace the tail parent_obj.select_set(True) in _regenerate_array_body
with tool.Blender.set_object_selection, which wraps select_set in the
hidden-object try/except the utility already owns.

Add tool.Array.is_array_child helper. Port decorator and MEP
action gizmos (lock, pen, join) hide on array children — writes
on children get wiped by the next regen, and the port topology
is inherited from the parent.
Introduce tool.Array.select_only_parent and wire it into both
bim.regenerate_array and bim.finish_editing_array so post-regen
state converges on parent-only-selected + active. Grow and shrink
paths otherwise diverge (grow left new children selected alongside
the parent; shrink left only the parent).

Sweep [0]-indexing in recreate_aggregate, recreate_connections,
and recreate_port_connections so batched N-child duplicates
recreate relationships on every new child, not just the first.
Single-source callers unaffected (loop collapses to one iteration
on 1-element lists).
Relates to #8088.

Replace N sequential duplicate_ifc_objects([parent]) calls in
_regenerate_array_body with one duplicate_ifc_object_n_times call
per layer, batching the fixed per-call overhead (snapshot gather,
UI refresh, decorator reload).
Guard batch_host_recut drain against dead StructRNA refs and prune
orphan array-child GUIDs at regen so outliner-delete of a
Bonsai-managed child cannot crash subsequent regenerate_array.
Recalculate walls after recreate_connections so Shift+D of
connected walls produces correct junction geometry without a
manual regen step.

IfcSurfaceFeature (e.g. road markings) adheres to a host element through
IfcRelAdheresToElement, a [1:1] cardinality hierarchical relationship in the
same family as aggregation, containment and nesting since IFC4.3. The spatial
traversal never followed it, so surface features had no resolvable parent or
container: on import they landed in the Unsorted collection instead of the
host's spatial collection, and were dropped entirely in DECOMPOSITION filter
mode.
Add get_adhered_element (feature to host) to the get_parent resolver chain and
walk HasSurfaceFeatures in get_decomposition, plus a get_surface_features helper
mirroring get_parts/get_contained. With get_parent resolving adherence,
get_container now returns the host's spatial container, so tool.Collector places
surface features under the host. Also follow HasSurfaceFeatures in the Bonsai
DECOMPOSITION filter path so they load in that mode.

file.write() streamed directly onto the target path, so a crash mid-write
left a truncated file with dangling STEP references. Serialize to a temp
file in the same directory, then atomically rename it onto the target.
- New IfcUtil::path::atomic_rename_file: std::rename on POSIX, MoveFileExW
with MOVEFILE_REPLACE_EXISTING on Windows. Unlike rename_file it never
unlinks the destination first, so there is no window where it goes missing.
- Fully in C++/swig (per aothms), so the FILE_NAME header is untouched: it
comes from the model header, not the output path (verified empirically).
- Temp lives next to the target so the rename stays on one filesystem.
- Stream is closed before the rename (Windows cannot move an open file).
- On any write error the temp is removed and the original target is intact.

roughnessFactor was computed as 1/specularity. An IfcSpecularExponent of
0 produced infinity, which nlohmann::json serialises as null and makes
the glTF invalid; exponents below 1 produced values above 1, which glTF
also forbids. Map exponents <= 1 to full roughness and keep 1/exponent
above that, so the factor always lands in [0, 1].

The georeferencing fix (e6dc582) iterates IfcProject.RepresentationContexts
unconditionally, but the attribute is OPTIONAL and None on projects without
contexts, crashing every extraction on such files with
TypeError: 'NoneType' object is not iterable.
Also extend the #8199 regression test to assert element placements are
copied verbatim, so extraction can never bake map coordinates into local
placements.

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.

std::to_chars is locale-independent, so the ostringstream and imbue(locale)
are no longer needed. Build the REAL string with plain std::string operations.
Output is unchanged (verified in standalone compile: same shortest values, all
round-trip). Addresses review feedback on #8309.

format_double formatted doubles with setprecision(max_digits10) (17 digits),
which padded clean values with noise: 0.0174532925199433 was rewritten as
0.017453292519943299 and 1.E-05 as 1.0000000000000001E-05. Every REAL in a file
changed on save, producing enormous diffs for anyone version-controlling IFC.
Use std::to_chars, which emits the shortest string that round-trips exactly
(like Python's repr), then keep the existing mantissa/exponent formatting.
Verified in a standalone compile of the exact function logic: the reporter's
values become 0.0174532925199433 and 1.E-05, 0.1 stays 0.1, and every tested
value (including a denormal) round-trips back to the identical double.

check_aggregate_of_type used an exact type comparison (element->ob_type ==
type_obj), so a numpy array was rejected because its elements are numpy scalars
(numpy.float64) rather than direct float instances. For the numeric types,
accept subclasses: PyFloat_Check for double (numpy.float64 subclasses float) and
PyLong_Check (excluding bool) for int. The SPF REAL vs INTEGER distinction is
kept, so a float is not accepted where an int is expected and vice versa.
This replaces the earlier Python-side walk() approach, which the maintainer
preferred not to take since walk() is removed in v0.9. Verified with a runtime
red-green (built as a shared lib, called via ctypes): the old check rejects
np.array([3.0, 4.0]) and the new one accepts it, plain lists still work, an int
list is still rejected where a REAL is expected, and bool is rejected for INTEGER.

asStringRef removes the first and last characters of a string, enumeration
or binary token to drop the delimiters, guarded only by !str.empty(). A
malformed single-character token (e.g. a bare '.' left when a fuzzer turns
'.PHYSICAL.' into '.)HYSICAL.') has length 1, so the first erase empties the
string and the second erase(str.begin()) runs on an empty string. That is
undefined behaviour: benign on a normal build, but it aborts (or throws
std::length_error from a later append) under a hardened libstdc++ with
_GLIBCXX_ASSERTIONS, which is why this file only segfaulted on the Fedora
build. Require at least two characters before stripping.

When ADD_COMMIT_SHA is off (the default for release tarballs), buildinfo.cpp
fell back to a hardcoded "0.8.0", so a 0.8.5/0.8.6 build reported 0.8.0 from
IfcConvert --version and in written file headers. Pass CMake's RELEASE_VERSION
(read from the VERSION file) to IfcParse as IFCOPENSHELL_VERSION_STRING and use
it as the fallback, mirroring how the branch/commit defines are handled. The
commit-sha build and the last-resort literal are unchanged.

generate_linework() loops over the main file plus any linked models
(added in 5db955d4), reassigning drawing_elements each iteration. The
SHAPELY fill pass builds elements_with_faces/raycast_objs from
drawing_elements, but did so once *after* that loop finished, so it
only ever saw whichever file was processed last -- silently dropping
surface fills for every other file, including the main model whenever
any link was loaded.
Accumulate elements_with_faces/raycast_objs across every file inside
the loop instead of capturing drawing_elements once after it ends.

The underlying bug (has_material_styles bypassing the tool layer) was
already fixed by e76455913, which added the required mock expectation
here, but left the test under its quarantine placeholder name
test_AAAAAAAAAAAA. Restore the real name now that it genuinely passes.
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.

ItemIsASum and Quantities are exporter columns that were missing from
MAIN_CSV_HEADER_COLUMNS, causing them to be misidentified as numeric cost
value categories on re-import. Also initialise rate_cost_schedule to None
before the search loop to avoid UnboundLocalError when no match is found.

is_drawing_active() required an open VIEW_3D area purely as a poll()
gate for bim.create_drawing, even though SVG generation is
ifcopenshell.geom-based with no viewport dependency; skip that check
when bpy.app.background is true, since a viewport is neither
obtainable nor meaningful there. Interactive behaviour is unchanged.
