Companion to the assign_type.py fix. The same class-pairing validation
added in 10ee5aef4f also gates the Bonsai-side type assignment UI via
tool.Type.is_relating_type_compatible, which the AssignType operator
uses to filter selectable objects. For annotation types (abstract
IfcTypeProduct), get_applicable_types(IfcAnnotation) is empty, so every
annotation was skipped with "No selected object can be typed by
IfcTypeProduct."
Honor the type's ApplicableOccurrence attribute as a fallback, matching
the core API fix. occurrence.is_a() handles subtypes and returns False
for unknown tokens, so free-form text is not trusted blindly.

The class-pairing validation added in 10ee5aef4f rejected every typed
annotation with "IfcTypeProduct cannot type IfcAnnotation ... (allowed
occurrence classes: <none>)".
The check derived allowed occurrence classes solely from the
buildingSMART implementer-agreement map, which has no entry for the
abstract IfcTypeProduct that Bonsai uses for annotation types (IFC4 has
no IfcAnnotationType). The intended occurrence class is declared in the
type's ApplicableOccurrence attribute (e.g. "IfcAnnotation/TEXT"), the
schema-defined mechanism for exactly this purpose.
Augment the allow-list with the ApplicableOccurrence class, but only
when its leading token resolves to a real entity in the schema so
free-form text is not trusted blindly. Genuine mismatches (e.g.
IfcWallType -> IfcWindow) are still rejected.

SHIFT+CTRL+CLICK on Activate Drawing now imports the
annotations of all selected drawings without switching
the active view or camera. The drawing camera is imported
when missing so annotations are collected into the correct
drawing collection. Loading is idempotent.

The drawing Include filter replaced the camera-view element set
entirely, so elements outside the camera boundary were drawn.
Intersect the filter results with the camera-view set instead.

The georef orientation gizmo (crosshair, project-north arrow,
grid-north arrow, true-north arrow, WCS leader) is a coordinate-
system overlay: its purpose is to communicate orientation regardless
of what the model contains, so it must remain visible regardless of
whether 3D geometry occupies the gizmo's z=0 footprint.
Wrap GeoreferenceDecorator.draw_geometry's draw cycle in a
gpu.state.depth_test_set("ALWAYS") / restore pair so the overlay
draws on top of any 3D geometry between the camera and the gizmo.
Matches the precedent set by the dashed-line overlay in
bim/module/model/opening.py.

Three crashes that surfaced when viewport decorators ran against
selected non-IFC blender objects or top-level objects with no
aggregate parent:
- WallAxisDecorator.draw_wall_axis: tool.Ifc.get_entity(obj) returns
None for a non-IFC selection (default cube, lamp, camera). The
subsequent element.is_a("IfcWall") raised AttributeError on every
redraw. Guard with `element and element.is_a(...)`.
- _ConnectedNetworkPathDecorator flow-segment loop: same shape;
iterates entries that may be None, calls .is_a("IfcFlowSegment")
unconditionally. Same guard.
- AggregateDecorator.draw_aggregate: indexes aggregates_list[-1]
unconditionally in the else branch; raises IndexError when the
selected element has no aggregate parent. Also leaves `aggregate`
unbound across loop iterations in the `in_aggregate_mode` branch
when `index <= 0`. Define `aggregate = None` per loop iteration
and guard the [-1] indexing with `elif aggregates_list:`.

Migrate 17 legacy viewport decorators (ClashDecorator, SolarDecorator,
MeasureDecorator, ItemDecorator, GeoreferenceDecorator, NestDecorator,
NestModeDecorator, GridDecorator, LoadsDecorator, AggregateDecorator,
AggregateModeDecorator, PolylineDecorator, ProductDecorator,
WallAxisDecorator, SlabDirectionDecorator, FaceAreaDecorator,
BoundingBoxDecorator) from hand-rolled install/uninstall lifecycles
onto the canonical tool.Blender.ViewportDecorator base. The legacy
uninstall removed each handler from Blender but never cleared
cls.handlers, growing a stale-reference list across enable/disable
cycles. The base's uninstall clears the list correctly.
State-derived install methods (ItemDecorator, ProductDecorator,
LoadsDecorator, PolylineDecorator) keep an install override per the
base's documented contract.
Drop the now-redundant per-class draw_batch copies and the module-
or method-scope transparent_color defs in favour of the base helpers
introduced in the preceding commit. system/decorator.py and
boundary/decorator.py keep their installed-flag lifecycle (different
pattern, no leak) but consume tool.Blender.transparent_color.
Add an AST forward-compat guard pinning the contract structurally:
any class declaring handlers = [] (Assign or AnnAssign) must subclass
tool.Blender.ViewportDecorator. Add a runtime regression on
ClashDecorator's install/uninstall cycle.

Add two helpers to tool.Blender that 17+ existing viewport decorators
re-implement byte-identically:
- ViewportDecorator.draw_batch(shader_type, content_pos, color, indices=None)
collapses the validate + batch_for_shader + uniform_float + draw cycle
every shader-driven decorator needs.
- Blender.transparent_color(color, alpha=0.1) is the RGBA-alpha-override
helper duplicated across nest, project, aggregate, model, system module
scopes plus six nested-def copies inside draw methods.
Pure additions on the tool/ layer with direct unit tests covering the
default-alpha, explicit-alpha, non-mutation, new-list-instance, and
validation-guard branches.

A pending RegionView3D.update() timer registered before wm.open_mainfile()
fires during the load against freshly-allocated regions whose GPU contexts
are not yet wired, CTD-ing inside GPU_matrix_ortho_set. Cancel both the
refresh and cap-rebuild timers in a new load_pre handler, hold a
_file_loading gate from load_pre through the first on_pre_view tick (first
paint = GPU ready), and short-circuit on_depsgraph_update during the
window so its IFC-reload schedule_refresh + apply_clip_planes_direct
branches can't re-arm against unready regions.

Collapse two parallel hand-maintained lists in the addon-preferences
PropertyGroups into derivations from `tool.Parametric.EDIT_TYPES`:
- GizmoPreferences: the 10 `<name>: BoolProperty` annotations now
generated from the full EDIT_TYPES list.
- DefaultParameters: add `has_default_parameters` flag to
ParametricObject (set True on door/window/stair/railing/roof);
derive the 5 `<name>: PointerProperty(type=BIM<X>Properties)`
annotations and collapse the 5 hand-written `draw_expandable_panel`
blocks in `draw_default_parameters` into loops driven by the flag.
Existing `test_gizmo_preferences_field_per_registry_entry` pinned the
GizmoPreferences contract; new
`test_default_parameters_field_per_registry_entry_with_defaults`
pins the DefaultParameters contract (one-directional: flag=True
implies field present, flag=False allows absence).

Refs gh#8088. Array regen + multi-opening drops fan out N+1 wall recuts
per operator (one per child filling deletion + the final mirror recut),
making CSG opening-subtraction O(N^2) for a linear UX action.
Introduces tool.Geometry.batch_host_recut() — a context manager that
coalesces switch_representation and bpy.ops.bim.update_representation
calls per voided element within one operator transaction. The drain
re-reads the active representation so the recut reflects current IFC.
Wraps 7 entry points (regenerate_array, RegenerateArray, RemoveArray,
AddOpening, RecalculateFill, CloneOpening, regenerate_from_type) and
rewires 7 leaf call sites in opening.py, void/operator.py, and
mirror_parent_void_fillings_to_children.
An AST forward-compat guard pins the rewire contract: no direct
switch_representation or bpy.ops.bim.update_representation in the
three target files outside the helper definitions.
A 16-child array regen now recuts the wall once instead of 17 times.
The CSG cost per recut is unchanged; only the count is reduced.
21 new tests across three lanes (helper unit, entry-point coalescing,
AST guard) — all green.

Mirror the icon-click entry into wall parametric edit on the TAB key.
The dispatch in Modifier.try_applying_edit_mode had no branch for fresh
LAYER2 walls, so TAB landed in item mode instead of the parametric
draft + gizmos. Add the missing entry leg of the toggle, placed after
the generic is_object_editing branch so the finish leg still fires
when a wall is already in edit mode.

Merging more than two IFC models with the MergeProjects recipe leaves
duplicated IfcGeometricRepresentationContext entities behind. All elements
are kept, but the accumulated contexts cause later disciplines to appear
"not merged" in viewers.
This test merges three projects and asserts the elements are kept, a single
IfcProject remains, and the geometric contexts are reused rather than
accumulated. It currently fails on the context assertion, reproducing #7973.

EnableEditingExtrusionAxis and EnableEditingExtrusionProfile both
import a mesh from the IFC representation into obj.data as their
first real action. That mesh-import overwrites any in-memory
parametric (gizmo) draft on the object, silently discarding the
user's pending dimension edits.
Concrete reproduction: drag a wall's length gizmo (draft pending),
then click "Edit Axis" before validating the draft. The axis-edit
imports the wall axis mesh; the in-flight draft vanishes; on
cancel the wall snaps back to its pre-drag length.
Both call sites now commit the active draft via
tool.Parametric.commit_object_draft before the mesh import, gated
on tool.Parametric.is_object_editing so the guard is a no-op when
no draft is in flight.

Multi-instance cache-lock, "Opening Cuts Skipped", and "Arrays With
Missing Children" banners now draw in BIM_PT_tabs alongside the
existing global error / outdated-model banners, so they remain
visible regardless of the active Bonsai tab. The corresponding
blocks are removed from BIM_PT_project. Dead imports
(is_cache_locked_by_other_process, draw_multiline_text) dropped
from project/ui.py.

regenerate_wall_representation returns None for walls without an
IfcMaterialLayerSet (the only mode it knows how to rebuild). Feeding
None to switch_representation crashes deep in resolve_representation
on .Items. Document the None return on the API side and bail in
tool.Model.recreate_wall when it hits.
