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.

mathutils only ships pre-built wheels for Python 3.13+ (verified
against PyPI's file list); on CI's Python 3.11, `pip install
mathutils` falls back to a slow/unreliable source build. Skip the
mathutils-dependent tests when the interpreter is too old instead.
These packages already have their own pytest suites (ifc5d, ifcedit,
ifcmcp, ifcquery) but were never run in CI, so regressions in them
went unnoticed. Add path triggers and test steps for all four, plus
odfpy and xlsxwriter which ifc5d's spreadsheet export tests need and
mcp which ifcmcp's server tests need.

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.

Linked IFC files were included in SVG output but without their

bpy.ops.bim.reload_link(link_index=...) from a script skips invoke(),
so self.query stayed at its empty default and execute() overwrote the
link's stored query, reloading everything. Only update link.query when
the property was explicitly set (dialog or script argument), and reload
using the stored query.

Store the selector query used at Link IFC time on the Link
PropertyGroup, restore it from the sidecar cache JSON on host
IFC reopen, and forward it through LoadLink and ReloadLink so
subsequent reloads replay the original filter instead of loading
every element. ReloadLink now opens a small dialog pre-populated
with the current query, allowing the user to edit it in place
without unlink-and-relink.
Also swap TestCalculateLinkMatrix off NamedTemporaryFile(delete=True)
which held an exclusive Windows handle and blocked the
code-under-test from reopening the sidecar path.

Fold two related cleanups from post-PR review into one commit:
Shared filling predicate — the gizmo poll and AddOpening._add_openings
both need to decide whether an IFC entity is a Bonsai-supported filling
(IfcDoor / IfcWindow, the classes the opening generator can derive
geometry from). Centralise the check in bim.module.model.opening as
is_filling_supported so a schema-broadening tomorrow only edits one
predicate. The gizmo's own predicate is renamed
is_supported_filling_or_opening to reflect its wider domain (also
accepts None for raw meshes and IfcOpeningElement for reassignment).
Aggregate-host guard — regenerate_filling_opening_body returns the
voided host Blender object so callers can recut it. Aggregates have
no mesh data; returning them made callers hit switch_representation
against a None data-block. Guard on voided_obj.data is None and
return None so callers can skip cleanly.
Adds a direct position_gizmos test asserting host-at-index-1 (filling
active) still anchors on the slab — pins the class-based dispatch's
selection-order independence.

Both files interleaved bpy.types imports with ifcopenshell.util
imports, which ruff's I001 rejects for standard-library / third-party
ordering. Running ruff check --fix on the two files reorders them into
the isort-canonical shape with no behaviour change.

EditOpenings.edit_openings unconditionally walked sibling wall sets
twice on every processed opening — once by mapped source id via
get_similar_openings_building_objs, once by filling type via
get_all_building_objects_of_similar_openings — and unioned both into
the building_objs recut set. reload_body_representation then hit every
one of those walls with a switch_representation call, even for the
show/hide toggle path where nothing about the opening changed.
Move both sibling-wall unions inside the is_edited / is_moved branch.
Pure show/hide (no shape edit, no move) now touches only the wall(s)
directly hosting the toggled openings. The edit and move paths still
refresh siblings the same as before, since a mapped-source rewrite
propagates the new shape to every sharing wall and each one needs a
recut.
Generated with the assistance of an AI coding tool.
recalculate_walls commits the wall's own placement to IFC before
recreating its geometry but did not touch its fillings. A door moved
along the wall's reference line therefore stayed cut at its old
position when the user pressed SHIFT+G on the wall, because the wall
recut ran against the still-stale opening placement in IFC.
Walk each wall's HasOpenings and, for every filling whose Blender
matrix_world differs from its committed IFC placement (tool.Ifc.is_moved),
commit the filling's placement and propagate the new matrix to the
enclosing opening via ifcopenshell.api.geometry.edit_object_placement.
The subsequent recreate_wall pass then sees the fresh opening positions
and cuts at the right spot.

Commit 82dd1d94d switched RecalculateFill from
bonsai.core.geometry.switch_representation to the surgical
tool.Geometry.recut_host to speed up batched host recuts. The trade-off
was intentional for that scope but dropped the implicit opening body
refresh that switch_representation used to provide: SHIFT+G on a door
whose parametric dimensions had drifted from its opening no longer
resized the opening, so the wall recut still hit a stale mapped source.
Extract a targeted single-source helper on tool.Model
(regenerate_filling_opening_body) that regenerates one filling's
mapped opening body via the existing FilledOpeningGenerator and
inverse-substitutes the new representation across every filling that
shares the mapped source. Refactor the family-wide caller
(update_simple_openings, used by the parametric-edit finish path) to
delegate to the same helper, deduped by source id so fragmented type
families where multiple mapped sources coexist all get refreshed.
Call the targeted helper at the top of RecalculateFill._recalculate_fills
for each distinct source among the selected fillings. All body-
representation lookups go through tool.Geometry.get_body_representation
rather than inlining the ("Model", "Body", "MODEL_VIEW") triple. An AST
forward-compat guard pins the call site.

The + gizmo previously appeared whenever a fillable host and any
non-host object were selected, so clicking it against an IfcCovering
crashed the geometry kernel when the opening generator tried to derive
a shape it couldn't build (AttributeError on 'NoneType.wrapped_data').
Tighten the gizmo poll to require the secondary selection to be a
class the operator can dispatch on: IfcDoor, IfcWindow,
IfcOpeningElement, or a non-IFC mesh. Make the poll selection-order-
independent so either click order activates it. Validate the same
class set at the operator boundary so keymap or scripted invocations
report a clear warning instead of crashing.
The narrower Door/Window support in the opening generator is a Bonsai
implementation limit, not an IFC schema restriction —
IfcRelFillsElement.RelatedBuildingElement is typed as IfcElement and
the schema permits any subtype. The tooltip and inline comment on the
validation branch note this so a future reader knows the gate is
future-work, not schema-mandated.
Rewrite the operator's bl_description to end-user-friendly wording that
drops the internal terms matrix_world and rl1/rl2.
Fixes#8215.
