Some distributions (e.g. Fedora) ship only a shared RocksDB that exports
RocksDB::rocksdb-shared rather than RocksDB::rocksdb. The CMake target
selection now falls back to the shared target when the static one is absent.
Newer RocksDB also changed DB::Open and DB::OpenForReadOnly to take
std::unique_ptr<DB>* instead of DB**. IfcFile.cpp uses SFINAE tag dispatch
to build against both old and new APIs without version detection.
CGAL 6.x deleted operator< from Point_d, so std::map<Point_d, ...>
no longer compiles. Adds a custom lexicographic comparator and updates
the three affected maps in snap_halfspaces and snap_halfspaces_2.
bim/handler.py was importing two feature-module internals
(wall_offset_gizmos.clear_caches, preview_base.discard_pending_previews)
to drain load-transient parametric state alongside the existing
tool.Parametric.heal_stale_edit_flags() call inside
_apply_save_file_invariants. Each new parametric drain added one
top-level import and one inline call — every load_post drain leaked
into handler.py's namespace.
Hide all three drains behind tool.Parametric.on_load_post(scene),
sited adjacent to heal_stale_edit_flags. The two feature-module
imports become late imports inside on_load_post — same pattern as
refresh_post_commit's existing `import bonsai.bim.handler` — which
sidesteps the tool.parametric -> bim.module.model.preview_base ->
bonsai.tool registration-time cycle.
The forward-compat AST contract that pinned "every module-scope
GenerationKeyedCache + clear_caches MUST be drained on load_post"
follows the call site to its new home — the test now walks
tool.Parametric.on_load_post instead of _apply_save_file_invariants.
No behaviour change. 45/45 affected bim tests pass
(test_handler_forward_compat, test_preview_base,
test_wall_offset_gizmos, test_parametric_registry).

edit-state props and walk BBIM_Array psets)
* WallGizmoPreviewDecorator + draw_wall_partner_bbox -> wall.py
(dereference wall.py-private classes and helpers via lazy
imports)
decorator.py keeps cross-cutting infrastructure
(BoundingBoxDecorator, SlabDirectionDecorator, WallAxisDecorator,
WallFilletPreviewDecorator, PolylineDecorator, ProductDecorator)
and the shared bbox primitives (bbox_world_edges,
draw_polyline_segments, _BBOX_EDGES, _stroke_lines_alpha,
_fill_quads_alpha) that several feature files now import.

Three concerns sharing the same architectural theme (collapse inline
bbox / edit-state lookups, drop overrides that re-do base-class work):
== Bbox helpers and array operator DRY ==
* tool/blender.py: add a "dimensions" tuple key to both
get_object_bounding_box and get_object_world_bounding_box return
dicts. The (max - min) per-axis extent — which callers previously
computed via local helpers — is now a key alongside min_x / max_x
/ min_point / max_point / center. Distinct from Blender's built-in
obj.dimensions (which folds object-level scale): the local variant
is the intrinsic mesh bbox extent; the world variant is the
matrix_world-applied AABB.
* bim/module/model/array.py: drop the local _bbox_dims helper; the
two callers now read tool.Blender.get_object_bounding_box["dimensions"]
directly.
* Rename _parent_geometry_changed -> _array_children_need_rebuild.
The old name suggested "did the parent change just now", implying
the function was a parent-edit-finish trigger. It actually runs
only inside the array-edit-finish path as a drift safety net (the
upstream-deliberate design — see commit 83d97d7e9 "Fix #7616. Make
regenerate array an operator instead of an array preference" —
means the array doesn't auto-regen when its parent geometry edits
finish). New name matches the call-site phrasing
``if X: _wipe_array_children(layers)`` and clarifies that this is
a children-state check, not a parent-edit trigger.
* Extract _resolve_array_edit_props(context) — returns the active
object's array props during an active edit lifecycle, or None.
Collapses the obj-active-then-is-editing prologue (3 lines + return)
to one resolver call across 4 sites: ToggleArrayMethod.execute,
AdjustArrayCount.execute, RemoveArrayLayerFromEdit._execute and
.poll. Each call site shrinks from 7 lines to 3.
* Migrate two inline bbox reads inside GizmoArrayEdition to the new
dict keys: get_axis_world_face_center collapses the manual
xs/ys/zs min/max + center math to bbox["center"] + bbox["max_x"] /
["max_y"] / ["max_z"]; get_element_height collapses
``max(corner[2] for corner in obj.bound_box)`` to
tool.Blender.get_object_bounding_box(obj)["max_z"].
The _BBOX_EQUALITY_EPS = 1e-5 tolerance stays inline as a single-
consumer constant — no other call site needs tolerance-equality on
dimension tuples, so extracting it to a shared util would be
speculative abstraction.
== Drop dead code ==
* GizmoArrayEdition.update_editing_gizmos override + its
_has_other_parametric_type helper: redundant with
hide_pen_button = True at line 1024. The base class already hides
the pen in every idle case (when hide_pen_button is truthy) AND in
every editing case (unconditionally). The override's conditional
hide-when-parametric only re-hid a pen that was already hidden in
both branches. Removes the only remaining path that could re-show
the array's pen icon; array-edit entry is now uniformly via the
per-layer ARRAY icons (which is the documented preferred
affordance, see the hide_pen_button comment).
* _wall_fillet_preview_active in wall.py: defined but never called.
_wall_fillet_props (the sibling thin-wrapper around
preview_base.get_preview_props) is heavily used; the
is_preview_active wrapper was added speculatively and never picked
up a consumer.
Generated with the assistance of an AI coding tool.
Bundled bug fixes + the forward-compat AST guard that prevents the
underlying class of bug from coming back.
* bim/module/model/wall.py: FinishEditingWall._execute early-returns
CANCELLED when props.is_editing is False. Without this guard, a
failed enable (e.g. on a wall without IfcMaterialLayerSetUsage)
leaves is_editing False but a press on finish still walked the
sub-ops below, which dereferenced layer-set-dependent state and
crashed.
* tool/model.py: Model.offset_wall now guards against
ifcopenshell.util.element.get_material returning None before
calling .is_a("IfcMaterialLayerSetUsage"). Fixes the pre-existing
test/bim/module/model/test_wall_header_refresh.py crash that has
been the only failing test in the wall lane since this branch
started.
* bim/handler.py: _apply_save_file_invariants drains
wall_offset_gizmos.clear_caches() on load_post. The module-scope
GenerationKeyedCache instance survives the .blend reload; without
the drain the cache may serve entries whose bpy_struct references
point into the freed bpy.data of the previous file.
* test/bim/test_handler_forward_compat.py: AST-walk test that
enumerates every bim/module/model/*.py source declaring both a
module-scope GenerationKeyedCache assignment AND a top-level
clear_caches function, and asserts each module appears as a
<module>.clear_caches() call in _apply_save_file_invariants. Pins
the contract: any future module-scope geom cache that exposes
clear_caches must wire into the load_post drain.
* test/bim/feature/model.feature + test/bim/test_feature.py: wall
edit-lifecycle scenarios switch from "add cube + assign as
IfcWallType" to "load the demo construction library + add an
occurrence of the WAL100 wall type", so the parametric edit runs
against a real LAYER2 wall with IfcMaterialLayerSetUsage rather
than a vanilla-mesh promotion that lacks one. The demo-library
step also picks the schema-matching library file (IFC2X3 /
IFC4 / IFC4X3) so the appended types remain valid across schemas.
Door saved-height assertion updates from 2.5 → 2500 to reflect
that BBIM_Door pset stores project units (METRIC_MM in the

Fixes builds with newer GCC/libstdc++ that no longer provide <cstdint>,
<cstring>, <cfloat>, <memory>, <algorithm> etc. transitively. Also
disambiguates visit<> calls in taxonomy.h with the full namespace and
casts the character value in IfcCharacterDecoder to uint32_t to silence
ambiguous overload warnings.
When HDF5 is found via its CMake config file, the code previously hardcoded
the hdf5_cpp-static target. On distributions that ship only shared HDF5
(e.g. Fedora rawhide where the config file was added in a newer package),
this caused a link failure. Now checks for hdf5_cpp-static, hdf5_cpp-shared,
and hdf5::hdf5_cpp-shared in order, falling back to module-mode discovery.
bpy.ops.bim.new_project(preset='demo') crashed in
refresh_bim_tool_headers: the post-commit hook fired for every
nested bpy.ops.bim.append_library_element during template
loading, and the operator context Blender hands to
programmatically-invoked nested operators is stripped of the
view-layer attributes the refresh reads.
Two changes resolve it.
Gate the header refresh in tool.Parametric.refresh_post_commit
on operator.bl_idname being one of the EDIT_TYPES finish_op
idnames. Only validate-gizmo commits (bim.finish_editing_<name>)
now trigger the refresh; demo-loader and other non-edit
operators skip it. Querying the registry directly is the
canonical signal — string-prefix matching would silently drift
if ParametricObject.finish_op changes derivation.
Harden tool.Blender.get_active_object so its view_layer fallback
also uses getattr; the 150+ callers routed through it now
tolerate stripped contexts. _resolve_bim_tool_context applies
the same defensive pattern to mode / workspace.
Tests:
- test_handler_restricted_context covers get_active_object's
defensive path and the BimTool-family whitelist (excludes
annotation, spatial, structural).
- test_handler_forward_compat AST-pins that the gate consults
EDIT_TYPES (not a string prefix).
- test_wall_header_refresh rewritten — three tests cover the
gated-by-registry contract: counter bumps for every commit,
finish_op operators refresh headers, others don't.
Hotkey-driven in-place edits (S_E / C_E) no longer trigger the
refresh — they were caught by the pre-refactor "every commit"
design. Left out of scope; the new skip-non-finish test pins
this as intentional.

Two related cleanups bundled because each was too small on its own.
== Drop dead Geometry.has_material_styles duplicate ==
Two parallel has_material_styles implementations existed on HEAD:
* Geometry.has_material_styles (tool/geometry.py:853, added by
3483683cb "Add tool.Geometry helpers for body representation +
placement"): checks each material via tool.Material.get_style
for an IfcSurfaceStyle. This is the implementation gizmos-8088
uses — its core/root.py:58 calls geometry.has_material_styles.
* Root.has_material_styles (tool/root.py:75, added by e76455913
"Route _has_material_styles through tool.Root.has_material_styles"):
checks each material for a HasRepresentation inverse. Added to
fix the test/core/test_root.py::TestCopyClass::test_AAAAAAAAAAAA
failure by routing the check through a Prophecy-mockable seam.
HEAD's core/root.py:59 calls root.has_material_styles. The Geometry
version became orphaned by that migration — zero callers historically
(git log -S "Geometry.has_material_styles" returns nothing). The
Root placement is the right architectural home: has_material_styles
pairs with assign_body_styles in the copy_class flow as "is there
material-defined styling? if not, apply body styling" — both
decisions live on the same interface, called in sequence from the
same caller.
The semantic delta (HasRepresentation vs IfcSurfaceStyle) is a close
approximation in real IFC files where HasRepresentation almost always
indicates a styled material; if precision becomes necessary, the
Root impl can be tightened independently of this cleanup.
Drop the Geometry method + its abstract declaration in core/tool.py.
== Sanitation sweep per CLAUDE.md §4a ==
Eight rot-prone references in code we authored on this branch get
their first-draft mistakes cleaned up. The §4a rule (no sibling
symbol names, no test paths, no motivation history in docstrings)
got added during this branch, so older commits sometimes named their
siblings in prose; this is a focused cleanup of the worst offenders.
* bim/module/model/wall.py:201 — _CommitWallDraftsFirstMixin
docstring carried motivation history ("...that every multi-wall
operator … used to repeat at the top of _execute"). Rewrite to
describe only the current contract.
* bim/module/model/wall.py:1910 — cycle_type_operator comment named
two sibling methods. Rephrase to describe what happens at the slot.
* bim/module/model/wall.py:2025 — _active_instances ClassVar comment
named WallGizmoPreviewDecorator. Rephrase to "the wall-gizmo
preview decorator" (role, not class).
* bim/module/drawing/gizmos.py:3402 — GizmoFillet hit_uses_bbox
comment named GizmoWallJoinIntersection. Rephrase to "the wall-join
gizmo group".
* bim/module/drawing/gizmos.py:3887 — GizmoCountLabel docstring had
a :meth:`set_count` cross-reference. Drop — reader sees the method
next to the class.
* bim/module/model/host_add_opening_gizmo.py:201 — poll-exclusion
comment named GizmoWallEdition + GizmoRoofEdition. Rephrase to
describe why we skip ("walls and parametric roofs both render
their own toggle in the pen row").
* bim/module/void/operator.py:45 — preserve_placement comment named
FilledOpeningGenerator.generate. Rephrase to "the filling-opening
generator gates its snap-to-wall-axis block on this flag".
* bim/parametric_lifecycle.py:64 — module docstring named the test
file path (test/bim/test_parametric_registry.py). Rewrite to
"enforced by the registry contract tests".
Sweep otherwise clean: no third-party software names in this-branch-
authored comments (upstream Revit / Tekla / ArchiCAD references are
legitimate external-constraint workarounds, §4a-allowed). No
PR/issue numbers we authored except the FIXME(PR5) in
tool/parametric.py:150, deliberately preserved until PR6's MEP slice
resolves it.

The 7 multi-wall operators (UnjoinWalls, UnjoinWallPathConnection,
ExtendWallsToUnderside, ExtendWallsToWall, SplitWall, MergeWall,
JoinWallsIntersection) each opened their _execute with an identical
prologue:
_commit_pending_wall_edits_for_selection(context)
# ... operator-specific logic
— flushing any in-progress wall parametric drafts so the operator
acts on committed IFC state rather than the draft preview box.
Extract that prologue into _CommitWallDraftsFirstMixin: its _execute
calls the commit helper, then delegates to a subclass-supplied
_perform. Subclasses inherit the mixin first in their bases tuple so
the mixin's _execute resolves first via the MRO. The IFC transaction
opened by tool.Ifc.Operator.execute still wraps both the commit and
the perform.
Behaviour-equivalent — same call, same order, same selection scope.
Architectural cleanup only: a future multi-wall operator can no
longer forget the commit step. The named helper
_commit_pending_wall_edits_for_selection stays as the single
encapsulation of the names=("wall",) filter; its docstring loses
the stale "every multi-wall operator calls it at the top of
_execute" sentence and now just describes the filter contract.
Matches gizmos-8088's _CommitWallDraftsFirstMixin pattern.

The regular bim.add_opening click on the host-add-opening gizmo
(wall + door/window co-selected) routes through
FilledOpeningGenerator.generate, which snaps the filling to the
wall's reference-line axis, optionally rotates 180° when the
filling sits on the opposite side, and re-applies an rl1 / rl2
Z-elevation default. That is the right default for "drag a fresh
door onto a wall and let the model place it for me", but defeats
the workflow where the user has already positioned the filling
precisely (e.g. snapped to a window in an adjacent wall, copy-
pasted at an exact Z, aligned to a reference object).
Holding SHIFT while clicking the gizmo now opts into a
"preserve placement" mode: the filling stays at its current
matrix_world and the opening is created at the filling's existing
position. The opening / filling rels and representation work are
unchanged — only the snap-to-axis branch is skipped, so the IFC
graph is identical to the regular click; only the spatial
position of the filling differs (user-chosen vs auto-snapped).
Implementation:
* bim/module/void/operator.py: AddOpening gains a hidden
preserve_placement BoolProperty + an invoke() that sets it from
event.shift. The call into FilledOpeningGenerator.generate
forwards the flag. bl_description documents the SHIFT modifier
so it surfaces in F3 search / hover tooltip.
* bim/module/model/opening.py: FilledOpeningGenerator.generate
accepts preserve_placement (default False — backwards-compatible
with the other caller, tool.Model.add_filled_opening). The
voided_obj.data-gated snap block (raycast + axis projection +
rl-Z default + filling_obj.matrix_world write) skips entirely
when the flag is True. The opening's matrix_world reads from
filling_obj.matrix_world below the gate, so the opening lands
at the filling's preserved position automatically.

The door / window / stair edit-row's type-cycle icon advanced one
type per click (CycleDoorType / CycleWindowType / CycleStairType
bound to cycle_type_operator). DoorType has 8 IFC variants,
WindowType 9, StairType 3 — so cycling past the target was the norm.
Threshold rule for cycle-vs-menu: cycle is appropriate for exactly 2
values (advance-one-per-click stays predictable). Three or more
values warrants a popup menu. Door / window / stair all qualify;
roof (RoofGenerationMethod has 2 values) keeps cycle. Wall has no
type cycle. Array is unaffected.
Swap to the popup-menu pattern (PickTypeMixin already on HEAD at
bim/parametric_lifecycle.py:442): clicking the icon opens a menu
listing all type_literal values; selecting one applies it in a
single undo step. The hamburger icon (VIEW3D_GT_menu) is wired into
BaseParametricGizmoGroup.setup_editing_gizmos whenever
pick_type_operator is set (mutually exclusive with
cycle_type_operator). Matches gizmos-8088's pattern exactly.
Per-feature shape:
* door.py: PickDoorType replaces CycleDoorType.
GizmoDoorEdition.cycle_type_operator → pick_type_operator.
* window.py: PickWindowType replaces CycleWindowType. Same swap.
* stair.py: PickStairType replaces CycleStairType (no
tool.Ifc.Operator inheritance — stair-type changes
BIMStairProperties only, no IFC mutation). Same swap.
* bim/module/model/__init__.py: registration entries renamed
Cycle* → Pick*.
* bim/module/drawing/gizmos.py: drop the
CycleTypeMixin / PickTypeMixin / TypeAccessorBase shim re-export —
its own docstring already noted "PR5 cleanup drops these" and the
three callers (door / window / stair Cycle*Type) it served are
gone. Roof's CycleTypeMixin import was already direct from
bim.parametric_lifecycle. Also update GizmoMenu docstring to
reflect the 2-vs-3+ threshold.

When entering parametric edit on a door or window that fills a
wall opening, four dimension gizmos now measure the distances
from the wall edges to the filling's jambs and from the wall's
base/top to the sill/header. Dragging any gizmo translates the
filling along the wall's local axis; 180°-flipped fillings and
slanted LAYER2 walls round-trip correctly. The has_host_wall
predicate hides all four when the filling → opening → wall
chain cannot be resolved.

Four concerns that together make the cursor-anchored gizmos
(extend_x_gizmo, extend_z_gizmo, split_gizmo on GizmoWallEdition)
fully functional and visually informative without entering parametric
edit mode first:
* Drop the props.is_editing gate in _update_cursor_gizmos. The three
bound operators (bim.extend_wall_to_cursor,
bim.extend_wall_height_to_cursor, bim.split_wall_at_cursor) already
poll on wall-selected and commit any pending wall edit before
acting, so single-click without entering edit mode is now the
canonical flow. Matches gizmos-8088's always-on behaviour.
* Register GizmoWallEdition instances in a per-region weakref map
(_active_instances) populated at setup_element_specific_gizmos
time. The WallGizmoPreviewDecorator dereferences this map to read
live is_highlight state off the cursor icons. Without the
registration its _cursor_icon_hovered always returned False and
the hover-gated GPU previews silently never drew. Mirrors the
same pattern already in place on GizmoWallJoinIntersection.
* Add post-operator resync to all three cursor operators
(_maybe_resync_wall_props_from_ifc for the single-wall split /
extend-height paths, _resync_walls_after_mutation for the
selection-wide extend-X path). Without this, props.length /
props.height stayed stale after the operator ran, so the
orientation flips _apply_wall_extend_flips computes from
cursor_local vs wall dimensions kept using the pre-extend values
until the next selection change. Matches gizmos-8088's pattern.
* Hover-gated GPU previews per icon:
- extend-X: filled Z=0 floor quads spanning the wall's offset to
offset+thickness Y band, visible from plan view without side-
view clutter. Grow case (cursor beyond either endpoint): one
green decorator_color_selected quad over the extension. Shrink
case (cursor inside extent): green quad for the portion that
REMAINS + red decorator_color_error quad for the portion the
operator REMOVES.
- extend-Z: vertical lines at the cursor's projected X in the
wall's y=0 reference-line plane. Grow case (cursor above wall
top): one green segment from z=height to z=cursor.z. Shrink
case: green from z=0 to z=cursor.z (REMAINS) + red from
z=cursor.z to z=height (REMOVES).
- split: one red vertical line at the cursor's projected X from
base to wall top — the cut plane.
Quads use QUAD_ALPHA=0.25 so the underlying wall body stays
visible.
* New module-level _fill_quads_alpha helper next to
_stroke_lines_alpha, plus a per-decorator _fill convenience method
and a _wall_floor_quad corner builder.
Modal-active gizmo hiding (is_gizmo_hidden_by_modal) is preserved.

Add openings — GizmoWallAddOpening only fired when a wall was active +
co-selected with a non-host; slabs and roofs got no in-viewport handle.
GizmoHostAddOpening covers all three host types via is_supported_host,
dispatching walls to the axis-projection anchor and slabs/roofs to a
world-Z anchor lifted just above the host's top face (predictable
height regardless of the void's vertical position).
Show openings on hosts with their own parametric-edit toolbar —
GizmoRoofEdition gains an idle-row toggle_openings_gizmo parallel to
the wall's, parked at the cancel-slot X next to the pen. Visible only
when the host carries HasOpenings and the edit triad is idle. Roof
overrides get_element_height to return the mesh's world-AABB top in
object-local Z, so the WHOLE pen-row anchors visibly above sloped or
stepped roof bodies. The wall's idle-row toggle now also hides when
HasOpenings is empty.
Show openings on hosts WITHOUT a parametric-edit toolbar —
GizmoHostToggleOpenings scoped strictly to the fallback case: a single
host selected, HasOpenings non-empty, NOT a path-connectable wall, NOT
a parametric roof. Covers slabs today plus any foreign-authored IfcRoof
without BBIM_Roof. Anchored at object origin XY + world-AABB top Z.
When slab parametric-edit eventually lands, the slab predicate joins
the exclusion list and this gizmo's poll narrows automatically.
Operator move — ToggleWallOpenings was already host-agnostic; renamed
to ToggleHostOpenings in opening.py (bl_idname bim.toggle_host_openings).
Three callers (the wall idle-row binding, GizmoWallFilletToggleOpenings,
and workspace.py's hotkey_A_O for Alt+O) now route through the renamed
operator. The Alt+O binding is surfaced in the operator's
bl_description so it appears in F3 search and hover tooltips.
DRY refactors —
* GizmoWallAddOpening deleted (subsumed by GizmoHostAddOpening)
* tool.Blender.get_object_world_bounding_box added as the world-AABB
sibling of the existing local helper; 3 inline call sites in
tool/misc.py (set_object_origin_to_bottom, scale_object_to_height)
and gizmos.py adopt it (2 other sites in drawing/operator.py and
project/operator.py inherently need raw transformed corners for
per-corner plane / NDC tests — not AABB candidates)
* BaseParametricGizmoGroup gains setup_pen_row_toggle_openings_icon +
update_pen_row_toggle_openings_icon; wall + roof + any future host
gizmo wire up the idle-row toggle with two one-line calls
* _resolve_active_host shared poll prologue between the two host
gizmos (gate + selection count + active-in-selected + entity lookup
+ supported-host check)
* HasOpenings non-empty checks at 3 sites route through
tool.Geometry.has_openings
* hotkey_A_O body collapsed to bpy.ops.bim.toggle_host_openings()
The forward-compat AST guard pinning "must accept fillet-corner walls"
retargets from GizmoWallAddOpening.poll to is_supported_host.

The extend-X / extend-Z / split icons share the cursor's projected X
on the wall axis, separated only by world Z (floor / cursor / wall
top). World Z collapses to a single screen point in plan view, so
every icon piled onto extend-X's hit target and only the topmost was
clickable.
Two refinements ported from gizmos-8088:
* When ``tool.Blender.is_view_top_down(context)`` reports the camera
is near plan-view, swap world-Z stacking for screen-up stacking:
anchor all icons at the floor world position and offset each by
``index * CURSOR_STACK_OFFSET`` along ``tool.Blender.get_screen_up_world(context)``.
Each icon lands in its own screen-space slot regardless of view
rotation.
* In the same top-down branch, drop ``extend_z_gizmo`` entirely. A
vertical-intent gizmo has no readable cue when looking down +Z —
clicking it would mutate the wall in a direction the user can't
see change.
* Bonus: split's local Z now goes through
``core.extrusion_depth_from_vertical_height(props.height, props.x_angle)``
so the icon lands on the slanted top edge of sloped walls (x_angle
!= 0) instead of the vertical-height target the wall isn't at.
All three helpers (``is_view_top_down``, ``get_screen_up_world``,
``extrusion_depth_from_vertical_height``) already on HEAD from PR2/PR3.
Non-top views unchanged — same world-Z stacking + cascading bumps as
before.

Hover-gated viewport preview lines that show where a wall-join /
extend / split operator would land before the user clicks. Four
preview paths, each gated on a specific icon's ``is_highlight`` state:
* **Join intersection** — two LAYER2 walls selected in the ``intersect``
state (non-joined, non-collinear, non-parallel). Draws four lines:
each wall's axis at both base and top Z, extending from the wall's
nearer endpoint to the projected XY intersection. The pair of lines
per wall communicates the full plane the join welds at, not just
the floor edge.
* **Cursor extend** — single LAYER2 wall, hover on ``extend_x_gizmo``.
One line from the wall's nearer X endpoint to the cursor's projected
X on the wall axis.
* **Cursor extend-Z** — hover on ``extend_z_gizmo``. Vertical line at
the cursor's projected X from wall base to cursor Z (the new total
height).
* **Cursor split** — hover on ``split_gizmo``. Vertical line at the
cursor's projected X from wall base to wall top — the cut plane.
Warning-red colour matches the icon's destructive-action signal.
Hover colour rules for the join preview:
* **Join or Fillet hover** → all four lines highlight in
``decorator_color_selected``. Both icons commit a symmetric corner
meet, so every line is part of the operation.
* **Extend-to-Wall hover** → only the non-active wall's two lines
(base + top) highlight. The default-direction extend operator
moves the non-active wall into the active one's axis; only that
wall's preview should signal motion.
* No hover → all four lines in ``decorations_colour``.
Three coordinated changes:
* ``bim/module/model/wall.py`` gains the ``_classify_wall_join_state``
wrapper over ``core.classify_wall_join_state`` (feeds the
``_are_walls_joined`` flag the core helper expects) AND a
``_active_instances`` per-region weakref ClassVar on
``GizmoWallJoinIntersection`` populated in ``setup()``. Without the
weakref registration, the decorator's ``_lookup_active_instance``
call returns None every frame and the hover gates silently
evaluate False — the symptom would be preview lines that never
switch colour. Both pieces ported from gizmos-8088.
* ``bim/module/model/decorator.py`` gains
``WallGizmoPreviewDecorator`` (~280 LOC across the four preview
paths + shared helpers ``_stroke`` /
``_active_layer2_wall_for_gizmo_preview`` /
``_join_group_hover_state`` / ``_extended_wall_index``). All
cross-file dependencies (``core.classify_wall_join_state``,
``core.wall_join_preview_lines``, ``_stroke_lines_alpha``,
``_cursor_icon_hovered``, ``_lookup_active_instance``,
``tool.Parametric.is_path_connectable_wall``,
``_wall_axis_world_segment_from_geom``) already on HEAD.
* ``bim/handler.py`` wires ``WallGizmoPreviewDecorator.install()`` /
``.uninstall()`` alongside the other always-on preview decorators.
The decorator self-polls every frame; cost is one selection-count
check + one ``is_highlight`` read when no eligible state is active.
Verified: headless smoke green, ruff + black clean. Live testing
confirms the four preview paths fire correctly when hovering each
icon.

GizmoWallJoinIntersection used to place its icons at state-specific
world points: join at floor Z, extend-to-wall at the active wall's
top Z, fillet stacked screen-up above join. Same XY at different Z
collapses to a single screen pixel in plan / top view, so two icons
became one hit target — invisible from above.
* position_gizmos now always-stacks along screen-up at a wall-top
anchor in both the joined (unjoin + fillet) and the intersecting
(extend + join + fillet) states. Order bottom-up is
extend / L / fillet. Collinear-merge keeps its single boundary
icon (no stack needed).
* New _stack_anchor_z picks the active wall's top Z (or the taller
of the two on mid-selection-transition frames). New _stack_at
lays a tuple of icons along screen-up at the resolved anchor.
* Glyph swap: join_icon -> VIEW3D_GT_wall_corner (L), extend_to_wall_icon
-> VIEW3D_GT_wall_tee (T). Both classes already existed in
bim/module/drawing/gizmos.py from an earlier commit; only the
setup() bl_idname strings changed. The previous arrow-merge /
arrow-extend pair read as the same direction once stacked.
Forward-compat AST contracts in test_wall_gizmos_forward_compat.py
pin the new invariants: the L and T bl_idnames must appear in
setup(), and position_gizmos must route through _stack_at so a
regression that reintroduces a direct billboarded_at write for any
state-specific icon fails CI before it flattens the stack again.
Also folds in a one-line typo fix in core/spatial.py:
assign_container's per-element can_contain check iterated `e` but
predicate-tested `root_element` (the outer for-loop variable), so
every element in the comprehension was tested against the same
container/element pair. Switch the argument to `e`.

Completes the PR4/PR5 cleanup the FIXME at tool/blender.py
flagged: every is_<type> / Array.<helper> shim on
tool.Blender.Modifier delegated one-for-one to tool.Parametric /
tool.Array. Callers now reach the canonical home directly, and the
shim block — seven is_<type> classmethods plus the inner class Array
— comes out.
Renames (no semantic change):
* tool.Blender.Modifier.is_<door|railing|roof|stair|wall|window>
→ tool.Parametric.is_<x>
13 sites across tool/loader.py, bim/import_ifc.py,
bim/module/geometry/{data,operator}.py, bim/module/model/{door,
railing,roof,stair,ui,wall,window}.py.
* tool.Blender.Modifier.Array.<helper> → tool.Array.<helper>
4 sites across tool/root.py, bim/import_ifc.py,
bim/module/geometry/operator.py.
* test_parametric_registry.py: the two getattr probes that hunt
predicates by name now look on tool.Parametric. Docstring + the
test function name (test_every_entry_has_modifier_predicate →
test_every_entry_has_parametric_predicate) follow the move.
Kept on tool.Blender.Modifier (non-shim, no equivalent on
tool.Parametric): try_applying_edit_mode,
try_canceling_editing_modifier_parameters_or_path,
is_eligible_for_<x>_modifier (×5), is_array_child, is_slab.
Verified: 109 model-lane tests + 8 parametric-registry tests pass
(the one pre-existing failure in test_wall_header_refresh.py is
unrelated — it patches handler.update_bim_tool_props which has been
renamed). git grep for tool\.Blender\.Modifier\.(is_<type>|Array\.)

Ports roof parametric edit gizmo group from gizmos-8088 and folds in
three roof-mesh bug fixes surfaced during live testing.
Port:
* ``CycleRoofGenerationMethod`` operator (bim.cycle_roof_generation_method)
cycles props.generation_method between "HEIGHT" and "ANGLE". Shift+click
cycles in reverse via the ``CycleTypeMixin`` contract.
* ``GizmoRoofEdition`` gizmo group: 3 dimension gizmos for height
(visible in HEIGHT mode) / slope angle with tan/atan2 rise round-trip
+ degree formatter (ANGLE mode) / roof_thickness. All three handles
anchor at the object's local origin and separate visually via their
declared axes (height/slope +Z, thickness -Z) — height + slope are
mutually exclusive via ``visibility_condition`` so they never paint
at the same time. Anchoring at the origin sidesteps the first-click
default-identity-matrix symptom that footprint-derived anchoring
would have hit on a stale ``RoofData`` cache.
* Lifecycle factory swap: explicit ``EnableEditingRoof / CancelEditingRoof
/ FinishEditingRoof`` classes replaced by ``tool.Parametric.build_edit_lifecycle("roof", _RoofEditMixin, ...)``.
Same bl_idnames out, no external caller changes.
* Registration: ``CycleRoofGenerationMethod`` + ``GizmoRoofEdition``
added to ``bim/module/model/__init__.py`` classes tuple.
* Tests: ``test_roof_gizmos.py`` covering slope round-trip, visibility
gates, cycle operator metadata, and origin-anchored positioning.
Bug fixes:
* ``generate_hipped_roof_bmesh`` flipped the bottom slab face's normal
at low slope angles. The kernel's outward-inference becomes
ambiguous on near-flat geometry once ``remove_doubles`` and
internal-face deletion run, and the early ``recalc_face_normals``
pass at line 389 ran BEFORE the topology was final. A second pass
on the final closed mesh fixes the eave plane (now reliably points
down regardless of slope).
* ``bpypolyskel.polygonize`` can emit a face whose vertex list
contains the same index twice on certain footprint/slope
combinations (a straight-skeleton ridge collapse). ``bm.faces.new``
rejects those with ``found the same (BMVert) used multiple times``,
aborting the whole rebuild. Filter the degenerate faces out so the
rest of the roof renders.
* ``_RoofEditMixin._restore_viewport_after_cancel`` now rebuilds the
bmesh from the just-restored draft via ``update_roof_modifier_bmesh``.
The hook was abstract on ``PathPreservingEditMixin`` and raised
``NotImplementedError`` on cancel-after-edit, leaving the user
stranded.
Also folds in a parallel ``tool/loader.py`` swap from
``tool.Blender.Modifier.is_railing`` to ``tool.Parametric.is_railing``
(consistent with the rest of the loader using ``tool.Parametric.*``).

Three wall-gizmo fixes:
* GizmoWallFilletPreview crashed on every draw_prepare after the
DRY-colors refactor moved decoration lookups onto
self.get_decoration_colors() — that method lives on
BillboardingGizmoGroupMixin / BaseParametricGizmoGroup, but
GizmoWallFilletPreview inherited only from bpy.types.GizmoGroup.
setup() AttributeError'd silently, leaving radius_dim and friends
unset. Add the mixin to the bases; rename _position_gizmos to
position_gizmos so the mixin's refresh/draw_prepare dispatch lands
correctly and drop the now-redundant overrides.
* GizmoWallAddOpening's poll gated on the strict is_wall predicate,
which rejects fillet-corner walls (no LAYER2 usage by IFC spec).
Switch to is_path_connectable_wall on both the active and the
partner-exclusion checks so the add-opening icon surfaces over
curved corners — matching every other wall-state gizmo's host gate.
* Show / hide openings was only available on LAYER2 walls because
GizmoWallEdition's parametric edit pipeline (which carries the
toggle) refuses fillet bodies. Add GizmoWallFilletToggleOpenings,
a dedicated single-icon group that polls on is_fillet_corner_wall
and reuses bim.toggle_wall_openings — the body stays untouched.
Forward-compat AST guards in test_wall_gizmos_forward_compat.py pin
both invariants: every wall GizmoGroup that calls
self.get_decoration_colors() must inherit a mixin that provides it,
and GizmoWallAddOpening.poll must keep using the looser predicate.

tool.Parametric.refresh_post_commit was calling update_bim_tool_props
after every IFC mutation. The function does two things — refresh
read-only header values (extrusion_depth/length/x_angle) and re-target
user-intent enums (ifc_class, relating_type_id) from the active object.
Doing both on the commit path crashed on IfcAnnotation actives (the
type isn't in the bim_tool ifc_class enum) and silently overwrote the
user's "what to build next" choice on every other element.
Split the function: update_bim_tool_props remains selection-driven and
does both halves; new refresh_bim_tool_headers is header-only and is
what refresh_post_commit now calls. Behaviour on selection change is
preserved. Also ports the upstream PR #8136 try/except guard onto the
props.ifc_class write for the selection-driven path. Adds
test_handler_forward_compat.py to pin both contracts via AST.

Two bugs in BIM_PT_array:
1. The "is this layer in edit mode" predicate compared a BoolProperty
against an int (props.is_editing == i). Python evaluates False == 0
as True, so layer 0 always rendered the per-layer edit form even
when no edit was active — clicking validate/cancel then dispatched
against a phantom edit state. Switched to
props.editing_item_index == i, which defaults to -1 and matches
exactly one layer when an edit is active.
2. The panel's CHECKMARK and CANCEL buttons called bim.edit_array /
bim.disable_editing_array, a parallel lifecycle that only cleared
editing_item_index. Entering edit mode via the viewport gizmo
(bim.enable_editing_array, the triad enter) sets is_editing=True
and hides array children; the legacy panel exit unwound neither —
so committing or cancelling from the panel left is_editing=True
with children hidden, and the viewport gizmo thought the edit was
still in progress. Re-bound both panel buttons to the canonical
triad operators (bim.finish_editing_array /
bim.cancel_editing_array), which _ArrayEditMixin already owns and
which the viewport gizmo group already uses. Panel and gizmo now
share one exit path.
The three now-unreachable operators are deleted with their
registration entries: EditArray (bim.edit_array), DisableEditingArray
(bim.disable_editing_array), and EnableEditingArrayItem
(bim.enable_editing_array_item, never called from any UI). The two
test/tool/test_model.py sites that drove bim.edit_array as a commit
step are switched to bim.finish_editing_array.
External scripts or user keymaps bound to bim.edit_array /
bim.disable_editing_array will need to update — the replacements are
bim.finish_editing_array and bim.cancel_editing_array, both taking no
parameters (the layer is read from props.editing_item_index).

The recent per-gizmo-prefs cleanup left ``update_swing_gizmos`` with a
stale ``prefs`` reference that raised NameError mid-refresh, so the flip
arc's ``matrix_basis`` was never reassigned and the gizmo drifted to the
world origin. SINGLE_SWING_RIGHT also lacked an X-mirror on the primary
arc, so the swing extended past the door's right edge instead of
sweeping back over the panel.
Five related fixes / additions:
* Drop the leftover ``prefs.decorations_colour[:3]`` per-frame colour
override (the setup-time ``decorator_color_special`` is the durable
contract — there's no reason to overwrite it every refresh).
* Add X-mirror to RIGHT-hinged single-panel transforms so the arc
sweeps back over the door rather than past the right edge.
* Treat DOUBLE_DOOR_SINGLE_SWING as a two-panel layout: 4 arcs total
(left + right panels, each with its own Y-mirrored flip) scaled to
``overall_width / 2``.
* Hide all swing arcs for SLIDING_TO_LEFT / SLIDING_TO_RIGHT /
DOUBLE_DOOR_SLIDING — sliding doors don't swing. A slide-direction
indicator is deferred to a separate change.
* Pin ``select_bias = -1000.0`` on every arc gizmo so the big
quarter-arc hit shapes don't steal clicks from the smaller dimension
and edit gizmos drawn on top.
Architectural cleanup driven by the same diff: the imperative
4-create + 50-line update block is replaced by a declarative
``swing_arc_props`` list of ``SwingArcConfig`` entries (mirrors the
existing ``dimension_gizmo_props`` pattern). Setup iterates the list
and creates one (main, flip) pair per entry under
``gizmo_swing_arc_<name>`` / ``gizmo_swing_arc_<name>_flip``; update
iterates the same list and positions each pair via the lambdas. Adding
a hypothetical multi-panel variant becomes a config entry rather than
two more attribute names plus a transform branch.
``ToggleDoorSwing`` gets a ``description`` classmethod that returns
user-facing wording per ``flip_geometry`` branch so the tooltip on
hover stops reading like operator internals.
``test/bim/module/model/test_door_gizmos.py`` (new) pins the
per-door-type contract: 11 cases covering LEFT / RIGHT hinge positions,
DOUBLE_SWING parity with SINGLE_SWING, DOUBLE_DOOR 4-arc layout, the
sliding-types hide invariant, ``is_editing=False`` hide invariant,
flip-arc matrix re-assignment, and world-matrix pre-multiplication.
Verified: ``pytest test/bim/module/model/test_door_gizmos.py`` 11/11

props.ifc_class is an EnumProperty whose items list only the element/space
types present in the model. Assigning element_type.is_a() crashed with
`enum "<class>" not found` when the selected element's type wasn't a member
(e.g. a raw IfcTypeProduct, or a stale item list mid-rebuild), aborting the
post-commit refresh.
Wrap the assignment in the same try/except TypeError guard already used for
the sibling relating_type_id assignments (added in 233cc344fa).

Add a clickable "xN" badge to GizmoStairEdition's edit row, mirroring
the array's popup-input UX: click opens a number dialog (no more
shift+click-into-modal). Text-only — no 2x2 grid glyph.
Structural changes that enable this cleanly:
* IconSlot.placeholder=True: slots reserve an X position in the row
without auto-creating a gizmo. Subclasses resolve the reserved X via
_slot_x_positions()[name] to place their own dynamic gizmos. Drops
the brittle "remember to add extra_gap_before" workaround that would
silently rot on slot reorders.
* Array bug fix: the count badge collided with the "-" icon because
the slot manager placed count_minus at the cycle position (X=0.87)
where ICON_NUMBER_X also lives. Migrating the badge to a placeholder
slot lets the manager allocate the X naturally and the "-" no longer
overlaps. ICON_NUMBER_X constant removed.
* IntegerInputDialogMixin in parametric_lifecycle.py: extracts the
popup-dialog plumbing shared between InputArrayCount and the new
InputStairTreads. Subclasses declare an IntProperty + attr_name +
props_getter; the mixin owns invoke/execute. _resolve_props helper
factors the common obj/props/requires_editing prologue.
Tests: BIM_GT_count_label registration; IconSlot placeholder contract
(no gizmo_idname required; gizmo_attrs() returns empty); the stair
edit-row slot layout reserves the label position between tread_lock
and plus at one ICON_ARRAY_GAP each; visibility propagates from
props.is_editing.

Three related cleanups in one pass:
* **Per-gizmo preferences removed.** The ``visibility_pref`` field on
IconSlot, the ``prefs.gizmos.<feature>.<icon>`` PropertyGroups, and
the dispatcher that surfaced them in the addon preferences UI are
all gone. ``update_gizmo_visibility`` loses its ``pref_enabled``
parameter — visibility is now driven purely by editing state and
modal gating. bim/ui.py drops ~257 lines of dead PropertyGroup
definitions; bim/__init__.py and tool/parametric.py shed their
matching wiring; door / wall slot declarations stop referencing
the now-nonexistent prefs.
* **Dynamic-wall face normals fixed.** ``regenerate_wall_mesh_from_props``
in wall.py now calls ``bmesh.ops.recalc_face_normals`` before writing
the mesh. Without it, walls regenerated from the parametric edit
draft could ship with inward-facing normals on some faces, which
rendered as visual holes under any backface-cull or normal-aware
shading. ``test/bim/module/model/test_wall_preview_mesh.py`` pins
the invariant (every face's normal points away from the wall centre).
* **Color constants DRY.** ``COLOR_RED`` / ``COLOR_GREEN`` /
``COLOR_BLUE`` / ``COLOR_NEUTRAL`` now live at module scope in
gizmos.py; the BaseParametricGizmoGroup class attributes alias the
same tuples so ``self.COLOR_GREEN`` keeps working. IconSlot
declarations in stair.py (plus / minus) and array.py (count_minus /
count_plus / delete) now reference the named constants instead of
duplicating the RGB tuples inline.

Hovering a wall-junction link-toggle icon today only swaps the icon
shape — the user doesn't see which wall the click will disconnect from
until after they click. ATPATH (T-junction) configurations especially
make the partner ambiguous when multiple connections sit close together.
On hover, paint a wireframe bbox around the partner wall using the same
shader, constants and color the array module already established for
its layer-children highlight (POLYLINE_UNIFORM_COLOR, decorator_color_special,
line width 1.8, alpha 0.8). The line-width / alpha constants in decorator.py
are renamed from _ARRAY_LAYER_BBOX_LINE_* to _BBOX_HIGHLIGHT_LINE_* and
shared between draw_array_layer_children_bbox and the new
draw_wall_partner_bbox so the two highlights stay in lockstep.
The trigger lives in a new GizmoWallLinkToggle subclass in wall.py
which keeps the base gizmos.GizmoLinkToggle generic (per the
generic-naming convention for shared widgets). The subclass's draw()
calls super().draw(context) then on self.is_highlight outlines its
partner_obj via the shared decorator helper. Same trigger pattern as
GizmoArrayLayerIndicator.
Blender's Gizmo API exposes target_set_operator but no symmetric
getter, so the partner reference can't be read back from the bound
operator handle. Instead GizmoWallUnjoinSingle.position_gizmos
mirrors the resolved partner_obj onto each visible icon every frame
next to the existing other_wall_guid write — the icon's draw() reads
from its own __slots__-declared attribute.
A forward-compat AST test pins the contract: GizmoWallLinkToggle.draw
must reference is_highlight and call draw_wall_partner_bbox. Catches
the regression where someone tidies the draw() override into super()
or replaces the shared helper with an ad-hoc draw call.

The parametric edit toolbar row used to assign each feature icon its
own ICON_<NAME>_X constant, with a separate FEATURE_ICON_MAX_X override
each subclass had to bump whenever a new icon was added. Forgetting the
bump silently collided icons — wall's rotate icon and the array button
both landed at X=1.24 in edit mode.
The new IconSlot dataclass + feature_slots tuple replace the
constants-and-override pattern with order-driven positioning: the
layout manager assigns each slot an X from its tuple index plus a
uniform ICON_ARRAY_GAP. Adding an icon is now a one-line append; the
"forget to bump" failure mode is structurally impossible.
Slot capabilities cover every existing icon-row shape:
* Single icon (wall rotate, array delete).
* N-variant slots — N gizmos at the same X with one visible per frame
via a subclass picker (stair tread-lock open/closed, wall baseline
exterior/center/interior). Pair becomes the N=2 case; triplet the
N=3 case. Variant idnames can be authored either as a tuple of
explicit names or as a string prefix that auto-suffixes _<variant>.
* Visibility prefs gate slot rendering without reflowing the row —
hidden slots still consume their X position.
* Extra per-slot gap before for visual separation (array's delete
trails the routine controls by an extra 0.2 m).
* Operator props forwarded to target_set_operator so adjusters
(+/-, increment) and generic toggles (property_name=...) work.
When the cycle slot is unused, feature slots collapse into the cycle
position so the row stays tight — that's how wall's baseline triplet
sits at X=0.87 without a gap before it.
Three subclasses migrate to the new system:
* wall.py — rotate icon + baseline triplet variants. Drops
ICON_ROTATE_X, _BASELINE_GIZMO_ATTRS, the manual triplet creation
loop, and the matching positioning block in _update_icon_row_extras
(it now just picks variant visibility).
* stair.py — tread_lock pair (open/closed) + plus + minus.
_update_editing_icon_positions reads slot X via _slot_x_positions
instead of three hardcoded constants. Also fixes the standalone
total_length_lock gizmo, which was broken since PR4 split
VIEW3D_GT_lock into open/closed pair (caller wasn't updated).
* array.py — count_minus + count_plus + method + delete (with
extra_gap_before=0.20 to separate the destructive action).
Drops the manual edit-row positioning loop entirely; the base
loop handles it. GizmoArrayChild now inherits BillboardingGizmoGroupMixin
and uses the shared setup_icon_gizmo helper, dropping its
duplicated _make_icon wrapper.
Two helpers added on BillboardingGizmoGroupMixin to fold the duplicated
prefs/color preamble that appeared at the top of six wall gizmo setups
plus the array-child setup:
* get_decoration_colors() — (decorations_colour, decorator_color_selected),
the active-state pair.
* get_unselected_decoration_colors() — (decorator_color_unselected,
decorator_color_selected) for gizmos surfaced on already-selected
geometry that should not pull focus.

The previous single-wall unjoin gizmo used a bracket-pair icon
(VIEW3D_GT_unjoin) that reads as "unjoin" only after you know what
it is, with no clear "linked" inverse — closing the brackets to
suggest the connected state collapses to a hollow square that
doesn't read as a link at all.
Add GizmoLinkToggle (VIEW3D_GT_link_toggle): two filled dots joined
by a horizontal connector in the default state. On hover the two
halves shear vertically apart — left dot+stub slip down as a unit,
right dot+stub slip up — with a horizontal gap at the centre,
signalling that a click will sever the underlying connection. The
glyph lives next to the generic icon classes (GizmoLockOpen/Closed,
GizmoArc) so any path / link / pair-of-connected-items context can
reuse it; it isn't wall-specific despite the first caller.
The class keeps its own per-state GPUBatch cache so the shape swap
on hover doesn't allocate per frame. The hit-shape is sourced from
the broken form (the larger bbox of the two states) so the cursor
doesn't lose hover at the offset dots' outer edges and flicker
between states.
GizmoWallUnjoinSingle.setup() now requests VIEW3D_GT_link_toggle.
The operator binding (bim.unjoin_wall_path_connection), the
POOL_SIZE, and the per-frame partner-GUID write are unchanged.

When the two source walls were placed at different elevations, the
fillet corner wall ended up with sub-degree X and Y Euler rotations
even though both source walls had only a Z rotation.
Cause: _apply_fillet_corner_geometry derived the corner's local X
axis from `chord = tangent_b - tangent_a` (a 3D vector). With walls
at different Z, `chord.z` was non-zero, so `x_dir = chord.normalized()`
inherited that Z component. The Z axis was already hardcoded to world
Z, so x_dir and z_dir were no longer orthogonal — the resulting
matrix_world was non-orthonormal, and Blender's Euler decomposition
surfaced the skew as the visible X/Y rotation drift.
Project the chord to the XY plane before normalising so x_dir is
strictly XY-aligned and orthogonal to z_dir. The corner wall is now
placed at wall A's elevation with a pure Z rotation, which matches
the user's expectation when both inputs are Z-aligned regardless of
their relative elevation.

When validate_type selected a preferred_item from remaining_items
(e.g. the sole IfcBooleanResult in a representation), it left that
item in the list. The subsequent Items filter removed every item,

"MappedRepresentation" — silently corrupting the representation.
Also removes temporary debug print statements added during

Re-running the operator on the same wall/slab pair created

extend_walls_to_underside now accepts multiple slab/roof
objects in a single operation — all selected non-LAYER2 IFC
elements are treated as clip targets, all LAYER2 elements as
walls. Placement sync is done once upfront; each wall is then
clipped against every selected slab before reloading.
Also adds bim.regenerate_wall_to_underside (Shift+G): after
moving a slab, re-clips connected walls using the existing
IfcRelConnectsElements(TOP) relationship. Old booleans are
removed via remove_representation_item before re-clipping.

When extend_walls_to_underside is applied to a wall and the

wall to the slab's new position.
The IFC relationship created by connect_wall_to_slab
(IfcRelConnectsElements, Description="TOP") is used to look
up which slabs a wall is clipped to. On regeneration, the
existing manual booleans (IfcPolygonalFaceSet operands) are
cleanly removed via remove_representation_item, then
clip_wall_to_slab is re-applied for each connected slab.
Shift+G on a LAYER2 wall that has a TOP connection now calls
bim.regenerate_wall_to_underside; walls without a connection
continue to call bim.recalculate_wall as before.

When the operator was called twice on the same wall for a
ridge roof, the two IfcPolygonalFaceSet clip solids shared
an exact ridge edge (kissing-solid). OCCT produced spurious
extra vertices at the coincident boundary.
Fix by building the clip solid from a rectangle on the slope
plane that extends slightly past the face edge (1 project
