Save-path:
* SaveProject._execute (project/operator.py) now calls
preview_base.discard_pending_previews(context.scene) right after
tool.Parametric.commit_pending_edits(). Previews are session-
transient — discard rather than commit. Sibling gizmo polls gate
on each preview's is_active flag; a stuck flag persisted through
the save would silently hide them on reload. Mirrors the pattern
already in gizmos-8088.
Preview-active gate hardening:
* preview_base.get_preview_props tolerates contexts without a
``scene`` attribute. Pre-existing tests use SimpleNamespace mocks
for the context; the previous getattr(context.scene, ...) raised
AttributeError before the inner default kicked in.
Test update:
* test_wall_header_refresh.test_geom_generation_invalidates_wall_geom_cache
patches tool.Wall.read_geometry instead of the now-deleted local
wall._read_wall_geometry (commit 7e5e7b8d6 migrated the call site).

The single-wall unjoin gizmo needs to enumerate every
IfcRelConnectsPathElements a wall participates in, regardless of which
side of the rel the wall was authored on, and place an icon at each
join's physical location. Two helpers carry that work:
_path_connection_location_world wraps core.compute_path_connection_location
at the Vector boundary. _iter_path_connections walks ConnectedTo +
ConnectedFrom, normalises orientation to (other, self_ct, other_ct),
and filters non-wall partners + None refs so per-frame gizmo positioning
survives malformed IFC.

DecorationsHandler now caches dissolved edges (mesh-keyed), world-space
draw payload, and GPUBatch objects with per-object epoch invalidation —
moving one wall doesn't wipe 50 opening caches. Object-mode dissolve
removes triangulation noise; 2-pass depth-test split dims occluded lines
instead of hiding them. Edit-mode behavior unchanged.
Also: disable viewport shadows for IfcFeatureElementSubtraction objects,
and wire DecorationsHandler.uninstall() into the model module's
unregister() so the new persistent handlers don't leak on addon disable.

Two paired test files for the framework infrastructure landed
earlier in this PR.
test_decorator_cache.py (11 tests):
* The 4-hook invalidation list (depsgraph_update_post + undo_post +
redo_post + load_post) is symmetrically managed by
install_decorator_cache_handlers / uninstall_decorator_cache_handlers.
A future edit that drops a hook from one side without the other
would land as a Blender segfault when a cached bpy.types.Object
ref outlives its underlying ID block — the regression must surface
as a test failure first.
* install is idempotent (calling twice doesn't double-register).
* uninstall when not installed doesn't raise.
* The bump handler accepts Blender's variadic args.
* The depsgraph predicate gates correctly: bumps on Object geometry
or transform updates, silently skips on Material / NodeTree / Image
updates (which would otherwise rebuild every cache on every node
edit).
* TokenCache.get_or_compute short-circuits on key+token match and
recomputes when the token bumps.
test_undo_resync_parametric_drafts.py (3 tests):
* UNDO_REGENERATORS keys must all be in tool.Parametric.EDIT_TYPES.
A typo would silently no-op on Ctrl+Z, restoring the desync the
helper is meant to prevent.
* The dispatcher skips objects with no active parametric edit
(undo_post fires for every undo, most of which touch zero drafts).
* The dispatcher silently skips parametric types that have no
UNDO_REGENERATORS entry (door / window / array are IFC-derived
with no draft preview mesh — they don't need a regenerator).
Mocks use spec=bpy.types.Depsgraph / spec=bpy.types.DepsgraphUpdate
/ spec=tool.parametric.ParametricObject so typos in mocked-attribute
access fail loudly (CLAUDE.md test discipline).

Splitting a wall through a door orphaned the door (door.FillsVoids
became empty). The fill rel was being reassigned by setting its
RelatedBuildingElement slot — schema-wise that's the filling slot, not
the wall slot — so when remove_feature deleted the old opening it
also cascade-removed the rel. Transferring via RelatingOpeningElement
keeps the rel pointing at the new opening so the door stays
associated. Pre-existing bug from 5a6476a57, surfaced by ef144dce2.

DumbWallJoiner.split assigned openings by projecting the opening's
centre-point onto the wall axis, so any opening whose footprint
straddled the cut was silently dropped from whichever wall its centre
missed. Now the full axis-projected extent (via ifcopenshell.geom.
create_shape) drives the assignment; for filled openings whose void
straddles the cut, a pure-void copy is added back to the neighbour
wall so its body is also cut.

Ctrl+Z / Ctrl+Shift+Z on an in-progress parametric draft (wall /
stair / roof) used to leave the preview mesh frozen in its
pre-undo shape — the IFC mutation rolls back but the bmesh built
from draft props doesn't repaint.
Add a registry of per-type regenerator functions
(``UNDO_REGENERATORS``) that re-build each type's preview mesh
from its current props. The dispatcher
``resync_parametric_drafts_after_undo`` walks all objects, skips
any without an active parametric edit, looks up the regenerator
by feature name, and calls it. Tagged 3D viewports for redraw.
Types without an entry (door / window / railing / etc.) are
intentionally absent — they're IFC-derived, so the undo's
representation rollback + next-frame refresh already repaints
correctly without a draft-side regenerator.
Undo/redo wiring is self-installed by
``bonsai.bim.parametric_lifecycle``: a ``@persistent``
``_resync_on_undo`` callback dispatches into the registry, and
``install_parametric_lifecycle_handlers()`` /
``uninstall_parametric_lifecycle_handlers()`` append/remove it
from ``bpy.app.handlers.undo_post`` and ``redo_post``.
``bim/__init__.py``'s ``register()`` calls the install function
*after* the central ``handler.undo_post`` / ``redo_post`` appends
so the regenerators see restored IFC state — ``bpy.app.handlers``
fire in append order. ``handler.py`` itself stays ignorant of the
parametric subsystem. The lazy function-local imports in each
regenerator break the addon-load cycle —
``bonsai.bim.parametric_lifecycle`` loads before
``bim/module/model/*``.

Three changes to the shared Enable/Finish/Cancel mixins:
1. Always-on drift triad on ParametricEditMixinBase. The base now
provides ``_handle_drift_on_enable`` / ``_handle_drift_on_finish``
/ ``_handle_drift_on_cancel`` classmethods, called from the
per-mixin ``_enable_one`` / ``_finish_one`` / ``_cancel_one``.
Pre-edit Blender-side translations commit to IFC on Enable
(apply_scale=False — only translation/rotation, not the user's
accidental scale), in-edit drag commits on Finish (apply_scale=True),
and Cancel restores the committed IFC placement via
``restore_or_rebaseline_placement``. Prevents the
"uncommitted drag disappears on Finish" and "preview snaps back
on Cancel" UX bugs.
2. ``_ParametricEditMixinBase`` renamed to ``ParametricEditMixinBase``
(public). Per-feature mixins that need to subclass directly
(e.g., when neither FeatureModifier nor PathPreserving fits)
can do so without reaching into a private name.
3. ``_update_modifier_bmesh`` (PathPreserving) renamed to
``_restore_viewport_after_cancel``. The old name was inaccurate
for subclasses that load a different IFC representation on
Cancel rather than rebuilding a bmesh preview from props.
Plus two polish changes:
* ``_mark_type_thumbnail_dirty`` helper on the base centralises the
``ifcopenshell.util.element.get_type`` + thumbnail-mark pattern
that both mixins repeated inline.
* ``FeatureModifierEditMixin._cancel_one`` and
``PathPreservingEditMixin._cancel_one`` wrap the restore in
``try/finally`` so ``props.is_editing = False`` flips even on
partial restore failure. Without this, a Cancel that raised
mid-restore would leave the user locked out of the edit lifecycle.
* ``PathPreservingEditMixin._finish_one`` / ``_cancel_one`` skip the
pset commit + viewport rebuild when the draft equals the stored
pset (no-op Enable→Finish round-trip should not pollute the
representation list or burn an undo entry).
``FeatureModifierEditMixin._finish_one`` now routes the pset commit
through ``tool.Pset.write_bbim_data`` instead of inlining the
``createIfcText(json.dumps(...))`` + ``ifcopenshell.api.pset.edit_pset``
dance. Two test assertions updated to match.

Surfaces any regression in:
* the modules dict in bim/__init__.py (added a folder, forgot the entry)
* PointerProperty wiring on bpy.types.{Scene,Object,...}
* registry-driven GizmoPreferences<Name> auto-registration in
tool.Parametric.iter_gizmo_preference_classes
* bpy.app.handlers append/remove balance
* every register()/unregister() across the 45+ feature modules
as a single PASSED/FAILED test instead of the silent "addon failed to
enable" users encounter in a fresh Blender. Paired with the existing

registry-shape regressions (operators/PropertyGroups/predicates) and
the registration-mechanics regressions (PointerProperty types not

test_parametric_lifecycle.py covers the door/window/railing/roof
state-transition contracts (enable/finish/cancel; no-op on
non-matching elements; draft preserved on finish-time failure)

test_parametric_registry.py gains a check that every is_<name>
predicate stays total (never raises on a non-matching IFC entity)
— a raising predicate would break the save path for unrelated
types. Also rewrites the gizmo-prefs check to read __annotations__
instead of hasattr, which depended on Blender registration timing.

When two GizmoDimension hit regions overlap (a short dimension
nested inside a longer one along the same axis), the larger one
used to win because hit boxes are scaled by world-space length —
the long box fully contains the short one, leaving the short
gizmo unreachable. The larger gizmo stays clickable at its
exposed ends, so smaller-wins is the right UX default.
Sets self.select_bias = -self._dimension_length inside
GizmoDimension.set_dimension_length. The smaller gizmo writes a
less-negative depth value in the GPU select buffer and wins the
tie-break. select_bias is unused elsewhere in the codebase, so
icon and arrow gizmos keep bias=0 and are unaffected (icons
correctly still win against dimensions, since 0 > -length).
Adds test/bim/module/drawing/test_dimension_gizmo_priority.py

set_icon_gizmo_position computed
``mw @ (Translation @ billboard_rot @ Scale)`` — the object's world
matrix was applied AFTER the billboard rotation, so any non-trivial
object rotation (e.g. a wall rotated in plan, a stair rotated to
match a corridor) carried over into the icon's transform and tilted
it edge-on to the camera instead of facing it.
Switch to ``billboarded_at(world_pos, billboard_rot, scale)`` where
``world_pos = mw @ local_pos``: translate to world space first, then
apply the billboard rotation independently of the object's rotation.
This matches the manual pattern the base class's
``update_editing_gizmos`` already uses for validate/cancel/cycle for
exactly this reason.
Drops the now-stale workaround docstring on
``GizmoWallEdition._update_icon_row_extras`` that documented why it
bypassed ``set_icon_gizmo_position`` — the helper does the right
thing now.
Adds ``test/bim/module/model/test_stair_gizmos.py`` as the regression
guard: parametrised over six rotation angles, asserts that the rotation
part of the resulting matrix equals ``billboard_rot`` (no contribution
from ``mw``'s rotation) and that the translation lands at
``world_pos``. Also exercises ``set_icon_gizmo_position`` end-to-end via
a stub gizmo to catch the exact shape of the previously-broken call
site.

Walls gain in-viewport parametric editing matching the door/window/stair
UX: drag handles for length, height, slope (x-angle), layer baseline
cycle, plus cursor-anchored quality-of-life operators (split at cursor,
extend to cursor, extend height, rotate 90, toggle openings) and
two-object state-machine gizmos (unjoin / merge / join-corner /
extend-to-wall / extend-vertically / add-opening).
Wall enters tool.Parametric.EDIT_TYPES, so save-time auto-commit,
GizmoPreferencesWall registration, and the in-progress-edit predicates
all light up automatically through the registry plumbing landed two
commits back.
The three-layer commit model (drag -> BIMWallProperties -> bmesh
preview -> Finish -> single ifc.run) means dragging a handle through
hundreds of intermediate values produces zero extra IFC entities. A
no-op enable->finish round-trip is byte-identical. The snapshot diff
in FinishEditingWall skips unchanged params.
_commit_active_wall_edit_if_any ensures cursor-anchored operators see
committed geometry, not the draft preview box.
Also lands the `prompt_auto_commit_parametric_edits` BoolProperty on
BIM_ADDON_preferences (consumed by the auto-commit dialog landed in
the framework commit) and refactors
`draw_{door,window,stair}_gizmo_parameters` into a shared
`_draw_parametric_gizmo_parameters` helper that the new
`draw_wall_gizmo_parameters` reuses. This commit and the framework
commit are stacked - the framework commit references the BoolProperty
defined here, so they must land together.
Tests cover pure math (core/test_model.py), DimensionGizmoConfig text
formatter, GizmoWallExtendVertically.poll() preconditions, and the
refresh_post_commit cache-invalidation regression. BDD scenarios in
model.feature cover the edit triad, auto-commit on save, and the
two-object gizmos. Documentation added to creating_walls.rst.

Establish a single source of truth for parametric element types (door,
window, stair, railing, roof). tool.Parametric.EDIT_TYPES drives:
- BIM<Name>Properties PointerProperty attachment via the registry
- GizmoPreferences<Name> class registration in bim/__init__.py
- save-time auto-commit of pending draft edits
- the refresh_post_commit epilogue called from IfcStore after every IFC
mutation, which fixes the stale-header bug where in-place hotkey
mutations (S_E / C_E) left BIMModelProperties and the gizmo cache
pointing at obsolete values.
Refactors door/window/railing/roof onto shared mixins from
bim/parametric_lifecycle.py (FeatureModifierEditMixin and
PathPreservingEditMixin); stair gets the lock-gizmo refactor and
frame-cache integration. Behavior preserved.
Adds BaseParametricGizmoGroup._prime_frame_caches so the parametric

rotation per frame; reorders poll() to short-circuit on the cheapest
predicate first. Adds the icon library + BillboardingGizmoGroupMixin

When a project has a ifc file associated, selecting non-ifc objects and duplicating them with SHIFT + D now correctly both duplicate them, keep the new objects selected and starts the transform modal. IFC objects behaviour is unaffected.
IFC2X3 representations have no HasShapeAspects inverse; opening the
Geometry & Materials subpanel on an IFC2X3 object raised AttributeError

MEP elements imported as tessellation / brep (no IfcExtrudedAreaSolid
or IfcSweptDiskSolid in their body representation) can't be
parametrically edited — the gizmos offer affordances the geometry
kernel has no path to honour. tool.System.has_parametric_body
inspects the Model/Body/MODEL_VIEW representation and returns True
only when at least one item resolves to one of the two
profile-sweep primitives.
The gate is wired into:
- GizmoMEPActions.is_eligible_object (the action icon group)
- _active_is_flow_segment / _active_is_bend_fitting visibility
predicates the icon row consults per-icon
- GizmoPipeSegmentEdition / GizmoDuctSegmentEdition is_element_type
tool.Parametric.is_pipe_segment / is_duct_segment stay IFC-class-only

Four standalone test files pinning contracts the production code

cache evicts on selection or generation change.
- test_mep_bend_preview_cache.py: bend decorator polyline cache
re-uses within a generation and rebuilds on generation bump.
- test_mep_distribution_fit_smoke.py: bim.fit_flow_segments
round-trips a 3-segment polyline without raising.

preview Enable* operator has a paired Cancel* operator with the

Two hot paths the gizmo polls fire every viewport event memoise
their result against tool.Parametric.get_geom_generation():
- tool.Blender.Modifier.any_selected_array_child caches the
per-selection scan against the selection identity-set + the
IFC generation token so a stable selection during a drag
doesn't re-walk every selected object's BBIM_Array pset every
frame.
- bim/module/model/wall.py grows a pair-predicate + connection
cache that the wall topology gizmos hit; both keyed on
(pair_uids, predicate_kind, generation) so a wall split or
axis edit invalidates correctly via the generation bump.
Behavioural contract is unchanged — stale entries are evicted
on generation bump; cache miss returns the same value the
un-cached path returned.

test was repeating.

Three concerns bundled by file boundary (all in mep.py):
- Extract bend preview operators + GizmoBendPreview into a focused
mep_bend_preview.py module; preview_base.py grows the shared helper
set both bend and other previews now consume; classes tuple in
model/__init__.py updated to register the new module.
- Surface ERROR reports on five silent CANCELLED returns in
MEPUnjoinAtPort / MEPRemoveTerminalFitting / MEPUnjoinPair so a
degenerate IFC file ("fitting has no Blender object", "connected
port leads nowhere") shows up in the popup instead of looking like
a no-op.
- DRY: _resolve_active_mep_segment + _require_port_state factor the
segment-id-or-active-object resolve + port-state guard out of every
port operator's prologue; _wire_anchored_icon_targets pulls the
GizmoMEPActions setup() body into an exercise-without-MRO helper so
the wiring-contract tests can hit it without instantiating the
GizmoGroup.

The opening preview's outline used a single-batch two-pass scheme that
dimmed the occluded back pass via alpha=0.25. The visible front pass also
inherited the source decorator color's modest alpha, so the outline read
as subtle on both sides.
Replace with a CAD hidden-line convention: solid full-alpha front pass on
the visible side, world-space dashed back pass on the occluded side. Both
passes use POLYLINE_UNIFORM_COLOR so depth and line-weight paths match.
The dashed batch is built once per object epoch by a new pure helper
tool.Blender.build_dashed_line_segments (pre-segments edges into world-
space dash chunks), then cached via the existing batch-cache mechanism
under "<uid>_dashed".
The solid front pass is rendered at a slightly wider line width than the
dashed back pass so its halo overpowers Blender's WIRE-display overlay
bias at outline pixels — without the asymmetry the wire's anti-z-fight
forward bias makes the LESS_EQUAL comparison narrowly fail and the
dashed pass wins on visible edges too.

while IfcSweptDiskSolid round-trip is broken upstream (#8106):
- profile cross-section sampling: circle returns 16 evenly-spaced

canonical corners; anything else returns None so the rep swap
is skipped rather than meshed against the wrong section
- parallel-transport framing keeps the cross-section continuous

- initial_basis override seeds the first ring with the source
segment's local +X / +Y axes, fixing the asymmetric-rectangle

inputs each refuses with CANCELLED:

the segment's port free; refuses on bridged fittings
- SelectMEPPathMembers walks IfcRelConnectsPorts in both
directions from the active segment and selects every fitting /

Pins two regressions the live MEP gizmo group can hit:
- per-icon setup() must write `position` (and `mode` on open-lock
icons) onto every target_set_operator result; the test stands in
for the AttributeError on bim.mep_add_obstruction that surfaced
when a field was dropped from the operator declaration
- each visibility_condition lambda must stay total against None /
non-IFC inputs, since a single raising predicate silently disables
every sibling icon in the group

ProfileDecorator.draw_faces (used by the roof path-edit overlay) and
SystemDecorator.draw_faces called bmesh.ops.triangulate on the live
bmesh — both mutated the input and produced ear-clip fans that rendered
as visible streaks across n-gon roof faces at alpha 0.1. The opening
DecorationsHandler edit-mode branch had a separate bug: it computed
triangles from obj.data.calc_loop_triangles() while iterating the
edit-mode bmesh, so any topology added mid-edit desynced the indices.
Centralise the correct draw path on tool.Blender.draw_bmesh_face_tris
(wraps bm.calc_loop_triangles, non-mutating, beauty triangulator) and
route all three call-sites through it. A forward-compat AST guard walks

A user clicking the pen icon on a typed-product occurrence whose body
representation is mapped from its type would silently mutate every
sibling occurrence's geometry. Add a confirmation dialog at the pen-icon
dispatcher (the single chokepoint every feature routes through) showing
the sibling count, with a session-scoped suppress checkbox.
The check is read-only: tool.Model.get_sibling_occurrence_count wraps
tool.Geometry.get_elements_by_representation against the resolved body
rep and subtracts self + type. A forward-compat AST guard pins the
dispatcher monopoly so any future feature that binds pen_gizmo directly
to a feature-specific enable op fails the test before merge.

Once a bend was created, the only way to retune start_length /
end_length / radius was to delete and recreate from scratch.
EnableBendPreviewFromBend re-opens the preview on an existing
parametric bend: it walks the bend's ports to resolve the two
connected segments, reads start / end length and radius from the
bend type's BBIM_Fitting pset, and sets editing_bend_id on the
preview props. MEPAddBend then deletes the old bend + its port
connections (single undo step) before the recreate path runs, so
finish replaces the bend in place and cancel discards the edit
without touching the original.
GizmoMEPActions surfaces a pen icon on single bend-fitting
selections via the new _active_is_bend_fitting predicate; the icon
dispatches the new operator. Mirror of the wall fillet re-edit
flow (EnableWallFilletPreviewFromCorner + editing_corner_id in
CreateWallFillet).
Test coverage: registration probe for the new operator, an attached
editing_bend_id field probe on the preview umbrella, and a
parametrized truth-table for the _is_bend_fitting predicate
(IfcFlowFitting with BEND PredefinedType, with other PredefinedType,
with no type, IfcFlowSegment, IfcWall, None).

Wall topology mutations (merge / join / extend-to-wall / unjoin /
fillet) applied to a Bonsai array child are silently overwritten by
the next ``regenerate_array``; merge also orphans a GUID listed in
the parent's ``BBIM_Array.Data``. Add a central
``tool.Blender.Modifier.any_selected_is_array_child`` predicate and
gate the five wall topology gizmo groups plus the six bound operators
behind it. Operator gating is defence in depth against keymap / F3
invocation paths that bypass the gizmo.
The base ``_wall_gizmo_poll_gate`` keeps its loose two-check shape
(viewport gizmos + no preview). A new
``_wall_topology_gizmo_poll_gate`` wraps it with the array-child
filter and is what the topology gizmos use. Host-opening gizmos
deliberately stay on the loose gate: openings authored on a child
are preserved through ``regenerate_array`` and track with the
replicated instance.
A forward-compat AST guard walks wall.py for ``GizmoGroup`` subclasses
and asserts each routes its poll through the tighter gate or the
central predicate, with an allow-list for the parametric-edit and
preview-owner exceptions. New wall topology gizmos inherit the
contract by construction.

Selecting a Bonsai-parametric IfcDoor now shows the swing arc(s)
without entering edit mode. A new viewport decorator polls on the
active object, reads the door's BBIM_Door pset, and draws the same
arcs the parametric door swing gizmo would draw — matching the
hinge / panel-width / x-mirror contract minus the is_editing gate.
A forward-compat test walks every door operation type and cross-
checks the readonly decorator's arc selection against the gizmo's
swing-arc config table, so future enum additions fail in both
surfaces simultaneously.
Also disables the inherited 8-pass dark halo on GizmoArc: an open
curve has no enclosed silhouette, so the offset passes read as
ghost arcs rather than a uniform outline. The arc's own cross-
section thickness keeps it legible without the halo.

GizmoWallEdition gains a fourth cursor-anchored icon that
spawns a perpendicular branch wall from the cursor's
orthogonal projection on the source wall axis. Click forms
a T-junction; shift+click forms an L-corner with the source
wall trimmed at the projection, keeping its longer portion.
The branch inherits the source's spatial container and
centerline baseline so its authored axis matches the source's
alignment rather than the type's default.
Also includes a floor-plane preview quad for the new gizmo,
a floor-Z cross line on the split preview for top-down
visibility, a small bump to QUAD_ALPHA for clearer preview
fills, and a stacking-offset helper that centralises the

billboarded_along_axis helper rotates the gizmo about the camera-
forward axis so its local +X aligns with the segment's local +Z
projected onto the screen, keeping the icon camera-facing but
visually following the extrusion direction. The flip-mirror branch
now reads from cursor-vs-current-end along the segment axis (not
screen-X), so the arrow points away from the current endpoint
regardless of viewport orientation. The split icon stacks
perpendicular to the rotated extend arrow in screen space so the
two don't overlap.
The decorator's green preview line no longer clamps the cursor
projection to min_projected_length — it follows the raw projection
so the line stays visible when the cursor crosses behind the
segment origin (the user still sees where they're pointing even
though the operator floors the actual commit).

The bend preview gizmo group (commit 2) populated a Scene draft but
the user saw nothing in the viewport until they hit finish — they
had to commit blindly. This commit ports the BendPreviewDecorator
(centerline arc + two leg projections on valid geometry, warning-red
axes on invalid in-segment intersections) and the interactive
GizmoBendPreview group (three dimension widgets for start_length /
end_length / radius plus validate / cancel icons). The bend axis
math lives in a pure compute_bend_preview_polylines helper, fed
into both the gizmo group's per-frame positioning and the GPU
decorator's draw path. MEPSegmentExtendPreviewDecorator lands at
the same time because it shares the decorator install / uninstall
plumbing — renders the extend-to-cursor preview line for the
GizmoPipeSegmentEdition / GizmoDuctSegmentEdition extend icons
when hovered, clamping the projected endpoint to the operator's
minimum so the preview matches where the commit lands. The
MEPJoinSegments dispatcher routes two selected MEP segments to
mep_add_transition (parallel) or enable_bend_preview (non-parallel)
— the F3 search entry point that makes the bend preview testable
before the gizmo-icon dispatch lands.
11 new tests in test_mep_bend_preview.py cover the geometry helper
truth table (parallel rejection, right-angle happy path, near-
collinear rejection, in-segment invalid_axes), the
_intersection_past_near parametrized boundary, registration probes
for the lifecycle operators / join dispatcher / gizmo group /
decorator, and the FinishBendPreview RuntimeError catch contract.
6 extend-preview-line tests (deferred from commit 3) join the
existing 35 in test_mep_segment_edition.py.

Spatial.get_root_element walks aggregate / nest / filled-void /
voided-element chains and core.assign_container assigns the container
to whatever the walk returns. For an IfcDoor the filled-void hop
redirects to the IfcOpeningElement, then voided-element to the host
wall, so a user who selects a door and runs bim.assign_container ends
up targeting the wall — and silently no-ops on the door if the wall is
already in the target storey.
Per IFC4 / IFC4.3 (IfcDoor, IfcWindow): the spatial containment of a
filling is defined independently of the filling relationship. Major
exporters (Revit, ArchiCAD, Tekla, Allplan) emit independent
ContainedInStructure on doors / windows accordingly. Drop the
filled-void / voided-element hops from the walk; aggregate and nest
remain — those are true sub-part relationships where the parent
legitimately owns the container.
New TestGetRootElement in test/tool pins the new contract (filling
resolves to itself) plus the retained aggregate / nest / loose-element
paths so a future PR that re-adds either hop is caught. Two new
TestAssignContainer cases in test/core pin filling-to-self through the
core layer and per-element can_contain filtering.

Pipe and duct segments had no parametric-edit affordance — the only
length edit path was a property panel value with no live preview.
This commit ports the per-segment parametric edit triad
(enable / finish / cancel) plus a cursor-anchored extend operator
and a cursor-projected split operator into one gizmo group per
segment type. The two PropertyGroups (BIMPipeSegmentProperties,
BIMDuctSegmentProperties) host the draft length plus snap fields
so cancel / no-op-finish restore the segment to its exact pre-edit
visual state including a non-identity pre-edit scale. Length
commits are written through DumbProfileJoiner.set_depth and
auto-dispatch bim.regenerate_distribution_element so adjacent
fittings track the port move. The split operator preserves
downstream port connectivity and runs through tool.Ifc.run for
single-step undo. The two segment types are now first-class
entries in tool.Parametric.EDIT_TYPES, which resolves the FIXME
on auto-commit-on-save dispatch.
35 unit tests cover predicate truth tables, segment_world_length
geometry, preview-via-scale / restore-scale helpers, gizmo class
wiring, lifecycle operator registration, dimension matrix_position
rotation respect, and lifecycle drift-handling. The 6 extend-
preview-line decorator tests stay deferred until the bend preview
decorator commit lands MEPSegmentExtendPreviewDecorator.

Parametric gizmos (wall/door/window/stair/roof/array/MEP) recompute
matrix_basis every frame from obj.matrix_world. While Blender's
transform modal (G/R/S and the Bonsai macro overrides) drags the
matrix, the gizmos slide off-cursor and fight the transform overlay.
Detect via context.window.modal_operators (Blender 4.2+) — the
collection of running modal operators. Gate poll() (forward-compat)
and draw_prepare() (production path: gizmo.hide=True preserves the
GizmoGroup across the drag instead of destroying it). Cover the
Bonsai macro override for G key (and Shift/Alt/Ctrl+Shift+D) by
matching the BIM_OT_* macro idnames that surface in modal_operators.
Forward-compat test walks every parametric-edit module for GizmoGroup
subclasses and asserts poll returns False with the detector mocked,
so new gizmo groups inherit the hide automatically.

Every preview operator (commit + cancel for both bend and wall
fillet) was inlining the same 3-4 line cleanup: set is_active to
False, zero every *_id IntProperty. The new clear_preview_state
helper in preview_base.py introspects bl_rna and applies that
contract generically — adopters become a single call. Two new tests
pin the contract: every *_id IntProperty zeroes, non-id fields stay.

Extract the pending_opening_recut tracking, three operators (apply /
dismiss / select), Project-panel banner, and the sibling
multi-instance warning banner (its backend helpers already landed
on this branch) from commit a85ed6032 on gizmos-8088.
All tool.* dependencies (Geometry.reimport_element_representations,
Blender.set_objects_selection, Array.*) and IfcImporter.gross_elements
are already on this branch -- no other diffs from a85ed6032 are
pulled.
The source's narrow except-tuple paraphrase comments are trimmed
to keep only the durable "don't swallow programmer errors" note,
per CLAUDE.md s4a.
Tests: 5 bim-lane tests in test/bim/module/project/
test_pending_opening_cuts.py covering apply happy-path + missing
entity, dismiss, select happy-path + cancellation.

When an operator mutated IFC then raised mid-execute the user was left
staring at a raw traceback with the IFC graph captured by the active
transaction but the Blender side stale. Blender does not push an undo
step for a raised operator (the same gap that the CANCELLED-modal arm
patches via bpy.ops.ed.undo_push), so the WARNING the framework can
emit is only honest if it pushes that undo step too. The framework
now detects partial state via ifc_file.transaction.operations,
pushes a Recover undo step, then reports a WARNING naming Ctrl+Z so
the recovery path is discoverable. The bespoke try/except wrapper in
UnjoinWallPathConnection becomes redundant and is retired in the
same change.

Three files flagged by black --check on the lint-formatting job:
* bim/module/geometry/operator.py — single-arg `.update(...)` rejoined
onto one line under the 120-char budget.
* test/bim/module/model/test_wall_gizmos.py — same join on a
_make_path_rel call.
* test/modal/test_modal.py — pre-existing baseline noise picked up
via the upstream merge: PEP-8 blank-line separators between top-
level functions, `0.68+` → `0.68 +`, double quotes, trailing
whitespace stripped.
No behavioural change; pure whitespace.
