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.

IfcConvert --version reported 0.8.0 on a plain source build even though the
VERSION file says 0.8.6 (#8164). buildinfo.cpp already falls back to the
IFCOPENSHELL_VERSION_STRING macro and CMake already passes it as
${RELEASE_VERSION}, but RELEASE_VERSION was only read from the VERSION file
when VERSION_OVERRIDE was on. A default build (VERSION_OVERRIDE off,
ADD_COMMIT_SHA off, as the nixpkgs package builds it) fell through to the
hardcoded "0.8.0", so the fallback macro carried the stale value.
Read the VERSION file unconditionally so RELEASE_VERSION is always the real
version. VERSION_OVERRIDE still governs the branch name embedded when
ADD_COMMIT_SHA is on, and project()/CPack now also reflect the true version.

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

Rename the streamer/sidecar transfer and record types to describe what
they are rather than how they move:
MeshChunk -> StreamedMesh
InstanceChunk -> StreamedInstance
InstanceCpu -> InstanceInfo
PackedElementInfo -> ElementTableRecord
uploadMeshChunk -> uploadStreamedMesh
uploadInstanceChunk -> uploadStreamedInstance
buildMeshChunk -> buildStreamedMesh
and the two post-index sidecar metadata blocks:
"critical" metadata -> "geometry" metadata (meshes/instances/georef/TOC)
"deferred" metadata -> "element" metadata (elements + string table)
parseSidecarCritical -> parseSidecarGeometryMetadata
parseSidecarDeferred -> parseSidecarElementMetadata
The one behavioural change: the element hierarchy (parent_id) was
carried through ElementInfo, ElementTableRecord, and the sidecar element
table but never consumed, so drop it and bump SIDECAR_VERSION 16 -> 17.
No back-compat: regenerate sidecars. sample.ifcview is regenerated at v17.

Full section tool for the web viewport, with the gizmo + interaction shared with
desktop from one codebase.
- True-face surface pick. pickSurfaceAt had always ray-cast the instance AABB (to
skip a depth readback), so cuts sat in front of the real surface. The pick
fragment already computes the exact world_pos (it clips sections with it); now
it OUTPUTS it to a 3rd pick MRT (RGBA32F) that every pick path renders, and
pickSurfaceAt / pickSurfaceAtAsync read it back (decodeMappedPickPosition;
ray-AABB kept only as a fallback). The web async pick chains id -> normal ->
position spontaneous staging maps.
- Web tool: LMB drops a cut at the picked surface (LMB drag still orbits), K
toggles, Shift+K clears; oriented to the real MRT surface normal. Exports + a
Section / Clear cuts toolbar pair.
- Shared gizmo: lifted the section-gizmo renderer (SECTION_WGSL + thick-line AA +
quad+arrow VBO + pack + screen-space hit-test) out of the Qt-coupled
OverlayRenderer into a Qt-free SectionGizmoRenderer that ViewportCore::render
draws for BOTH desktop and web (both already render via render()). One identical
gizmo; OverlayRenderer's now-dead section code removed. Fixed 1 m size (matches
the desktop constant).
- Interaction (shared): hitTestSectionGizmo (SectionGizmoRenderer::hitTest) +
beginSectionDrag / updateSectionDrag / endSectionDrag live in ViewportCore.
Drag a gizmo arrow to slide the plane along its normal; Del/Backspace removes
the most recent cut. Desktop's ViewportWindow dropped its duplicate hit-test /
drag math + state and delegates to the core; web wires the same calls.
Tests: sectionPlaneCount add/clear/cap (Catch2, 125); web smoke "click a surface
cuts geometry, clear restores" exercises the shared gizmo + 3-MRT pick (11/11).
Desktop object-pick / marquee unaffected; BonsaiViewer builds.

Bring rubber-band box-select to the web on the Web preset's select button (RMB).
- Core: factor the pick-pass encode + rect copy out of picksInRect into
encodeBoxPickToStaging (mirroring how single-pick shares
encodePickReadbackToStaging), shared by the sync picksInRect (desktop) and a
new async picksInRectAsync (web) — the latter maps the staging buffer via a
spontaneous callback because the sync spin-map hangs the JS loop. New
applyMarqueeToSelection (plain replace / Shift add / Ctrl remove).
- Web main_web: a select-button drag past the click threshold draws a marquee
rubber-band (a plain DOM <div> positioned in CSS px — no GPU overlay pass,
which the web lib lacks) and on release box-picks the rect (device px) and
applies it to the selection. A click (no drag) still single-picks.
- Web shell.html: the #marquee div + styling, and — the reported bug — a
contextmenu preventDefault on the canvas so RMB (now the select button) doesn't
pop the browser menu. (Firefox still forces its native menu on Shift+RightClick;
that's a browser escape hatch pages can't override.)
Tests: applyMarqueeToSelection replace/add/remove + id-0 (Catch2, 124 total);
web smoke marquee drag → rubber-band shown → selection changes → hidden (10/10).
Desktop picksInRect unchanged in behaviour; BonsaiViewer builds.

Make orbit/pan/select mouse bindings pure data owned by ViewportCore so both
hosts and every preset share one source of truth, and add a "Web" preset. This
rounds out the matrix: the desktop gains a web-style scheme and the web inherits
all presets, with no per-platform hardcoding.
- Core: NavBindings { orbit, pan, select button + modifier } + setNavPreset
("blender" default | "rhino" | "revit" | "web") + navBindings(). Select is
preset-driven too (was hardcoded LMB) so "web" moves it to RMB. web = orbit
LMB, pan MMB, select RMB (LMB drag orbits with no click/drag ambiguity; RMB
click-selects / drag-marquees). NavMod uses "Plain" not "None" (X11 #defines
None to 0L).
- Desktop ViewportWindow: applyNavPreset sources the core table (mapped to Qt);
marquee-arm / single-pick dispatch keys off select_button_. Default stays
blender → no behaviour change.
- Desktop config: AppSettings::NavPreset gains Web + navPresetName(); the
Settings dialog lists it. This also FIXES a pre-existing gap — the preset combo
was persisted but never applied (only WGPU_NAV_PRESET env worked). MainWindow
now applies the persisted preset at startup (env override still wins) and live
on navPresetChanged, so all four presets actually work from the dialog.
- Web main_web: classifyPress routes the pressed button through navBindings()
(orbit/pan/select), defaulting to the "web" preset; context menu already
suppressed so RMB is free.
Tests: setNavPreset table (Catch2, 123 total); web smoke select tests use RMB.
BonsaiViewer builds; 9/9 web smoke.
