Gorgious56 a3533bfa49 Adopt _CommitWallDraftsFirstMixin on 7 wall operators
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.

Gorgious56 e0aa39068d Shift-click add-opening preserves filling placement
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.

Gorgious56 81bacb5899 Use menu pick gizmo for door / window / stair type
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.

Gorgious56 56097694bf Add host-wall offset gizmos for door/window edit
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.

Gorgious56 d0334a72ab Show wall cursor gizmos outside edit mode + axis previews
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.

Gorgious56 046917f75d Generalise opening gizmos + DRY toolbar plumbing
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.

Gorgious56 c398deba71 Stack cursor-anchored wall gizmos along screen-up in top view
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.

Gorgious56 5ce7d6f834 Port WallGizmoPreviewDecorator from gizmos-8088
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.

Gorgious56 497acc3d19 Stack wall-join trio along screen-up + L/T glyphs
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`.

IfcRelConnectsElements(TOP) relationship. Old booleans are

wall to the slab's new position.

The IFC relationship created by connect_wall_to_slab

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.

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
unit margin) rather than the exact face footprint. Adjacent
slope solids now volumetrically overlap at the ridge instead
of sharing a boundary face, which OCCT handles correctly.

Tiago Azevedo c559ee0015 Fix sign of temporary offset restore in sweep_along_curve
The temporary-offset workaround (#7408, commit bd57cc8735) subtracts the
directrix centroid (`mean`) from the curve points before building the
sweep near the origin, then must add it back to restore the original
location. The restore negated the sign — `Move(-mean)` instead of
`Move(+mean)` — placing the swept solid at -mean (mirrored through the
origin) rather than its true position.

Only triggers for polyline directrixes (`is_polyhedron()`) whose centroid
is more than 100 m from the origin (`mean.norm() > 1e2`), so models
centered near the origin are unaffected. Models that keep absolute site
coordinates (e.g. many Revit/ODA IFC exports) render affected swept
solids — reinforcing bars, pipes — at a mirrored phantom location far
from the rest of the model.

Gorgious56 d71856d884 Migrate Modifier shim callers + drop the shim block
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

Renames (no semantic change):

  13 sites across tool/loader.py, bim/import_ifc.py,
  bim/module/geometry/{data,operator}.py, bim/module/model/{door,

* 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.

tool.Parametric): try_applying_edit_mode,
try_canceling_editing_modifier_parameters_or_path,
is_eligible_for_<x>_modifier (×5), is_array_child, is_slab.

Gorgious56 0c8b6e93c6 Add GizmoRoofEdition + fix low-slope normals + cancel restore
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.*``).

Gorgious56 e1ab5047b0 Fix fillet preview crash + surface openings on fillet walls
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.

Gorgious56 28491b290a Split update_bim_tool_props commit vs selection
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.

Gorgious56 645054aa6a Wire array panel buttons to triad lifecycle
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).

Gorgious56 95ad96c25e Fix door swing arcs + declarative SwingArcConfig
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

Gorgious56 a2d600b9af Add IconSlot placeholders + stair xN tread label
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.

Gorgious56 fbfbe93550 Drop per-gizmo preferences + fix dynamic-wall face normals + DRY colors
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.

Gorgious56 782f25bd31 Highlight partner wall on link-toggle hover
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.

Gorgious56 f2868c2631 Replace hardcoded icon-X constants with IconSlot layout manager
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.

Gorgious56 a48f326ab2 Add link-toggle hover gizmo for wall junctions
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.

Gorgious56 49fe0756fa Fix spurious X/Y rotation on fillet corner wall
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.

Gorgious56 1534003e51 Fix fillet partner missing from wall unjoin gizmo
GizmoWallUnjoinSingle.poll accepts fillet-corner walls via the looser
tool.Parametric.is_path_connectable_wall predicate (fillet corners
have no LAYER2 usage by IFC spec, but they still participate in
IfcRelConnectsPathElements). The partner filter inside
_iter_path_connections used the stricter tool.Blender.Modifier.is_wall
(LAYER2-only), so adjacent LAYER2 walls silently dropped their
fillet-corner partners from the connection list — the unjoin icon
appeared when the fillet wall itself was selected but not on either
of its LAYER2 neighbours.

Switch the partner filter to is_path_connectable_wall so host and
partner predicates match. Add a regression test for the fillet case
and an AST forward-compat guard pinning the predicate symbol so a
future "tidy the imports" can't silently re-introduce the asymmetry.

Gorgious56 ea487fb17c Add array parametric edit lifecycle + GizmoArrayEdition / Child
Ports the array parametric-edit lifecycle, gizmo group, child guard,
per-layer ARRAY entry icons, and the array bbox decorators
(preview + selection highlight + layer-children) from gizmos-8088.
Restores the array_gizmo icon's positioning + visibility in the
framework's parametric edit row.

Registry (tool/parametric.py):
* EDIT_TYPES adds ParametricObject("array", supports_build_edit_lifecycle=True).
  _ArrayEditMixin in array.py feeds build_edit_lifecycle which auto-
  generates EnableEditingArray / FinishEditingArray / CancelEditingArray
  with the conventional bl_idnames the gizmo references.

tool/blender.py:
* Adds is_array predicate wrapper around tool.Parametric.is_array.
  The registry contract test test_every_entry_has_modifier_predicate
  enforces every EDIT_TYPES entry has a matching is_<name> wrapper on
  tool.Blender.Modifier.

array.py (+1130 LOC port from gizmos-8088):
* _ArrayEditMixin(ParametricEditMixinBase) drives the auto-generated
  enable / finish / cancel lifecycle.
* GizmoArrayEdition: validate + cancel + count display + +/- adjusters
  + method toggle + delete button + per-layer ARRAY entry icons
  (preallocated pool of MAX_LAYER_GIZMOS=8).
* GizmoArrayChild: child-array gizmo for the array-replica case.
* EditArrayFromChild: resolves the spawning layer via
  tool.Array.get_child_layer_index so clicking a child's array gizmo
  opens the layer that produced that child rather than always layer 0
  (the gizmos-8088 source itself hardcoded item=0; HEAD has the helper
  to do it right).
* New operators: EnableEditingArrayItem, ArrayParentGizmoClick,
  ArrayGizmoClick, ToggleArrayMethod, RemoveArrayLayerFromEdit,
  InputArrayCount, AdjustArrayCount.

prop.py: BIMArrayProperties gets per_child_opening BoolProperty
(when the array parent fills a host, give each child its own
opening + filling pair).

Bug fix: guard update_relating_array_from_object against the
cleanup-time None set. _finish_one writes relating_array_object = None
to clear the source-array reference; that fired the update callback,
which dispatched bpy.ops.bim.enable_editing_array(item=self.is_editing).
With is_editing just flipped to False, the bool coerced to 0 and
re-opened layer-0 edit immediately after every validate. The guard
short-circuits on None; item is also fixed to 0 (the bool-as-layer-
index was always meaningless for the legitimate user-pick path).

decorator.py (+312 LOC, all ports from gizmos-8088):
* bbox_world_edges / draw_polyline_segments / _BBOX_EDGES - shared
  geometry helpers usable across array decorators.
* draw_array_layer_children_bbox - green wireframe bbox per child of
  one array layer, drawn inline from a gizmo's draw() so the highlight
  tracks the hover cursor without POST_VIEW lag.
* ArrayPreviewDecorator - faint cyan ghost bboxes at each future
  array instance during the edit lifecycle (offset math mirrors
  Model.regenerate_array, gated on props.is_editing).
* ArraySelectionHighlightDecorator - bounding-box overlay surfacing
  the array family of the selected object. Child selected -> parent
  in special color + siblings in unselected color; parent selected
  (idle) -> all children in unselected color. TokenCache-backed.

handler.py: imports + uninstall/install the 2 always-on decorators in
_install_viewport_overlays. Both self-poll, so installation has no
cost when no array is selected / in edit mode.

Registration (bim/module/model/__init__.py):
* Adds the 3 lifecycle classes generated by build_edit_lifecycle
  (CancelEditingArray, EnableEditingArray, FinishEditingArray) -
  they exist as module-level names but are only visible to Blender's
  operator registry when included in the classes tuple.
* Adds the 8 new operators + 2 new gizmo groups in alphabetical order.

gizmos.py: restores the array_gizmo icon position + visibility block
in BaseParametricGizmoGroup.update_editing_gizmos. Was force-hidden
in c250b2c1a because no array gizmo existed; the icon's plumbing
comes back online now that GizmoArrayEdition is registered.

Verified by test/bim/test_parametric_registry.py: all 8 tests pass -
enable/finish/cancel ops resolve, PropertyGroup attached, is_array
predicate present, predicate is total on non-matching elements.

assign_body_styles — they're called in sequence as "is there a
material style? if not, assign body style"). core/root.py now
calls root.has_material_styles(new) like every other dependency,
fixing the test failure and dropping the ifcopenshell.util.element
import that was the only consumer of the ifcopenshell import at
module load in core/root.py.

Three test files covering PR4's new surfaces — preview registry,

preview keys, operator names, or helper function names, so adding a

  contexts without a scene (regression guard for the SimpleNamespace
  bug fixed in commit ee63137c6).
* ActivationCycle (registry-driven loop): any_preview_active toggles
  with each registered preview's is_active flag;
  discard_pending_previews clears every active flag across every
  registered preview.
* SaveOnDiscardWired: locates the bim.save_project operator
  dynamically and verifies its execute path references the discard
  helper by its actual __name__.

test_wall_gizmo_poll_gate.py (4 tests):
* WallGizmoGroupsHideDuringPreview: walks the wall module for
  bpy.types.GizmoGroup subclasses (skips preview-owner exceptions
  whose bl_idname contains 'preview'), mocks any_preview_active to
  True, and asserts every discovered gizmo's poll returns False.
* BaseParametricGizmoPollHidesDuringPreview: mirrors the test for
  the cross-feature parametric framework base class.

test_fillet_operators.py (3 tests):
* FilletOperatorsRegistered: at-least-four-ops + every-discovered-op-
  is-callable. Catches accidental deregistration.
* EnableRejectsIneligibleSelection: poll returns False without a
  selection so the operator is greyed-out in menus.

State-clearing tests via bpy.ops.bim.cancel_wall_fillet_preview() are
deliberately omitted — the operator early-returns when context.screen
is unattached and prior tests in the model lane can leave the screen
in that state, making the dispatch path inherently flaky. Live testing
covers the behaviour.

Net: 13 tests pass cleanly in both single-file and full model lane.

Gorgious56 3f5273744d Discard previews on IFC save + harden preview-active gate
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).

Gorgious56 d6f55b0bf0 Drop wall.py local read_geometry + validate dupes + relax gates
Two cohesive cleanups in one commit.

A. Migrate wall.py to PR3-absorbed tool methods (fixes bug 4: pen icon
missing on fillet corner walls):

PR3 shipped tool.Wall.read_geometry + tool.Wall.validate_for_parametric_edit
but wall.py kept local duplicates predating that work. The local
_read_wall_geometry guards on tool.Blender.Modifier.is_wall (LAYER2-only)
while the tool method guards on tool.Parametric.is_path_connectable_wall
(LAYER2 OR fillet corner). Consequence: _get_wall_geom_cached → local
_read_wall_geometry returned None for every fillet corner →
GizmoWallFilletReedit.position_gizmos hit `if geom is None: hide` →
pen icon was unreachable for every fillet corner the user created.

Three _read_wall_geometry callers migrated to tool.Wall.read_geometry
(_read_wall_state_into_props, _get_wall_geom_cached,
GizmoWallJoinIntersection.position_gizmos). Two
_validate_wall_for_parametric_edit callers migrated to
tool.Wall.validate_for_parametric_edit (_maybe_resync_wall_props_from_ifc,
EnableEditingWall._execute). Local helpers deleted; docstring references
updated.

B. Drop over-restrictive gizmo gates (fixes bug 1: join icons missing
when walls intersect away from endpoints):

GizmoWallJoinIntersection.position_gizmos no longer hides itself when
the projected intersection lands further than MAX_DISTANCE_TO_ENDPOINT_
FACTOR (0.75 wall lengths) from any endpoint. The remaining
PARALLEL_DOT_THRESHOLD (cos 2°) gate via project_axis_intersection
returns None for near-parallel walls and is the only correctness bound;
distance from endpoints is a UI concern, not a geometric one.

GizmoWallFilletReedit.poll drops the has_a / has_b ConnectedFrom +
ConnectedTo guard — the IsFilletCorner pset is the authoritative signal.
EnableWallFilletPreviewFromCorner.execute already separately validates
both neighbour connections and reports a user-facing error if either
side is disconnected.

Gorgious56 bf6fd52786 Hide sister gizmos during preview + ESC cancels + DRY wall polls
Three live-session regressions surfaced after the fillet feature
landed.

Sister gizmos competed with the active preview:
* preview_base.any_preview_active(context): new helper iterates the
  PREVIEW_CANCEL_OPS registry and returns True if any preview is open.
  Future previews registered there automatically gate sister gizmos.
* BaseParametricGizmoGroup.poll (gizmos.py): short-circuits on
  any_preview_active so every parametric gizmo (door/window/stair/
  roof/railing/wall edition) hides during ANY preview.
* The 4 wall gizmo groups with explicit polls (GizmoWallAddOpening,
  GizmoWallExtendVertically, GizmoWallJoinIntersection,
  GizmoWallUnjoinSingle) + GizmoWallFilletReedit gain the same gate.

DRY: extract _wall_gizmo_poll_gate(context):
* 5 wall gizmo polls each duplicated the 2 pre-flight checks
  (viewport-gizmos enabled + no preview active). The helper centralises
  them — each poll becomes a single short-circuit line followed by its
  per-feature selection inspection.

ESC cancels the active preview:
* try_cancel_active_preview already existed in preview_base since PR3
  but had no caller. Hooked into OverrideEscape.execute (geometry/
  operator.py) as a new elif branch — same keymap that already cancels
  pen gizmo edit mode + item mode + edit mode + aggregate mode. Order
  in the branch chain matters: try preview cancel before falling back
  to try_canceling_editing_modifier_parameters_or_path so the in-
  flight preview wins over a stale modifier-edit cancel attempt.

Gorgious56 9f748fa4a9 Add wall-fillet feature: operators, gizmos, decorator
End-to-end fillet flow on top of the helpers + recreate_wall hook
(landed in the previous commit). Users select two LAYER2 walls, click
the fillet entry icon, drag the live radius widget, and validate to
replace the corner with a curved LAYER2 corner wall (banana body).

Operators (5):
* EnableWallFilletPreview: 2-wall selection → validates LAYER2 +
  straight axis + zero-slope + intersect-or-joined state → seeds the
  preview props with a default radius computed from the shorter
  available leg.
* FinishWallFilletPreview: dispatches CreateWallFillet with the tuned
  radius; clears preview state on FINISHED, preserves it on failure so
  the user can re-tune without re-selecting.
* CancelWallFilletPreview: clears preview state, no IFC mutation.
* EnableWallFilletPreviewFromCorner: pen-icon re-edit on an existing
  fillet corner — pre-fills the preview from the corner's BBIM_Wall
  pset + walks the inverse graph to recover wall A and wall B.
* CreateWallFillet: deletes any prior corner + A↔B path connection,
  shortens A and B to the tangent points, instantiates a corner wall
  from A's type, unassigns the swept-layer material/type (the explicit
  banana body MUST own its geometry), assigns the dominant material,
  rebuilds the body, sets a straight 2-point chord axis, stores
  BBIM_Wall.IsFilletCorner+FilletRadius, reconnects A and B to the
  corner with NOTDEFINED on the corner's side.

Gizmo groups (2 new + entry icon on existing):
* GizmoWallFilletPreview: visible while a preview is active. Bundles
  a radius_dim widget at the arc apex, a trim_dim widget along wall A
  expressing the same DOF via the leg setback distance
  (trim = |radius| * tan(sweep/2)), and validate / cancel icons
  anchored above the apex in screen-up.
* GizmoWallFilletReedit: pen-icon entry on an existing fillet corner
  wall (single-selection, BBIM_Wall.IsFilletCorner set, both neighbour
  connections present). Mutually exclusive with an active preview.
* GizmoWallJoinIntersection now stacks a fillet entry icon
  (VIEW3D_GT_fillet → bim.enable_wall_fillet_preview) above the
  existing join/unjoin icon in the joined and intersect state branches.

Property + decorator infrastructure:
* prop.py: BIMWallFilletPreviewProperties (Scene-level draft) +
  BIMPreviewProperties umbrella with only the wall_fillet pointer.
  The umbrella is the seam preview_base.py (landed in PR3) already
  reads via getattr(scene, "BIMPreviewProperties", None).
* decorator.py: _stroke_lines_alpha helper + WallFilletPreviewDecorator.
  Polls is_active; renders leg projections + arc + arc-center
  construction lines from tool.Wall.compute_wall_fillet_geometry.
* __init__.py: registers operators + gizmo groups + property groups +
  wires Scene.BIMPreviewProperties.
* handler.py: WallFilletPreviewDecorator.install/uninstall in
  _install_decorators — always installed, self-polls on is_active.

Drive-by: extract gizmo.get_screen_up(billboard_rot) helper —
the local +Y of a billboard rotation is the camera's screen-up world
direction. Replaces 4 inline `billboard_rot @ Vector((0.0, 1.0, 0.0))`
sites added across the fillet feature's gizmo groups.

Gorgious56 eeede522d9 Add wall-fillet helper functions + recreate_wall hook
Eleven module-level helpers in wall.py that the upcoming wall-fillet
operators + gizmo groups depend on. Each is self-contained or
references only helpers earlier in the file; the operators and
gizmos themselves land in follow-up commits.

* _wall_fillet_props / _wall_fillet_preview_active /
  _wall_fillet_preview_walls: thin read-side accessors over the
  BIMPreviewProperties.wall_fillet pointer (added with the
  operators commit). Safe today: get_preview_props returns None
  until the pointer is attached.
* _walls_have_zero_slope_for_fillet: validates that input walls
  are vertical (x_angle ~ 0); slanted-extrusion fillets require
  swept-along-curve geometry the banana profile builder doesn't
  support.
* _build_curved_corner_body_representation: builds the banana
  (annular sector) IfcExtrudedAreaSolid as a polyline-tessellated
  IfcIndexedPolyCurve.
* _apply_fillet_corner_geometry: positions the corner wall at
  tangent_a and rebuilds its body. Shared by the creation operator
  and the regenerate path.
* _resolve_two_walls: pulls (active, other) from a 2-wall
  selection, validates both as LAYER2 + straight-axis + not-already-
  a-fillet-corner.
* _pick_dominant_wall_material: returns the thickest layer's
  material from an element's IfcMaterialLayerSet / Usage.
* regenerate_fillet_corner_wall: re-runs the geometry build from
  BBIM_Wall.FilletRadius + current neighbour layer parameters.
  Called by tool.Model.recreate_wall when the IsFilletCorner pset
  is set; the FIXME(PR4) placeholder in recreate_wall is dropped.
* _wall_fillet_gizmo_x_matrix: 4x4 placement matrix with local +X
  aligned to a world-space direction; used by the fillet preview
  gizmo group.

Centralises the IsFilletCorner pset read as
tool.Parametric.is_fillet_corner_wall — replaces 3 inline
get_pset(element, "BBIM_Wall", "IsFilletCorner") sites
(tool.Model.recreate_wall, tool.Model.recalculate_walls,
tool.Parametric.is_path_connectable_wall) plus the new
_resolve_two_walls call.

Gorgious56 d955763f63 Gate parametric-edit array gizmo until integration completes
The framework's parametric-edit icon row currently binds an array
icon to bim.add_array_from_feature_edit, but the supporting per-
feature add-array flow and gizmo positioning haven't fully landed.
Showing the icon today lets the user click it and trigger a half-
wired flow.

Force the icon hidden inside the props.is_editing branch of
BaseParametricGizmoGroup.update_editing_gizmos. The else-branch
(not editing) already hides it, so this just mirrors that behavior
during edit mode. Drop this gate when array integration completes
to re-enable the icon position + visibility plumbing.

Gorgious56 93c51c1a39 Add cursor-aware extend-arrow flip on wall edit gizmos
The extend-X / extend-Z icons in GizmoWallEdition's cursor row are
billboarded toward the camera; without orientation polish they
always point in the same screen-space direction regardless of which
wall endpoint the click will move (or whether the cursor sits above
or below the wall top). New helper mirrors the icon's local-X (extend-X)
or local-Y (extend-Z) axis so each arrow points toward the end it
will move:

* Extend-X: walk wall midpoint to figure out which endpoint stays
  fixed (cursor past midpoint → ATSTART stays; cursor before midpoint
  → ATEND stays). Project the fixed endpoint into screen-space and
  flip the arrow when the gizmo's anchor sits on the same side.
* Extend-Z: flip when the cursor is below the wall top (within
  EXTEND_FLIP_EPSILON tolerance).

Called once per resolved cursor gizmo from
``GizmoWallEdition._update_cursor_gizmos``, after the gizmo's
``matrix_basis`` is set by ``gizmo.billboarded_at``. Reuses
``gizmo.should_flip_extend_arrow`` + ``EXTEND_FLIP_MIRROR_X/Y`` +
``EXTEND_FLIP_EPSILON`` already on tool.

Gorgious56 deaf090a50 Add single-wall unjoin operator + gizmo group
GizmoWallJoinIntersection's unjoin only fires when exactly two walls
are selected and surfaces one icon at their shared corner — useless
when the wall has 3+ joins and the user wants to disconnect just one.

* UnjoinWallPathConnection: surgical counterpart to UnjoinWalls.
  Disconnects the active wall from a single partner wall identified
  by IFC GlobalId (invariant under Blender-object renames + file
  save/reload + undo). Walks both inverse arrays of the active wall
  for the specific IfcRelConnectsPathElements joining the pair —
  matches DumbWallJoiner.split's pattern and avoids disconnect_path's
  direction-sensitivity. Resyncs both walls' draft props after the
  recreate_wall pass.
* GizmoWallUnjoinSingle: activates on exactly-one selected
  LAYER2 wall. Preallocates a pool of 16 unjoin icons (Blender forbids
  gizmo allocation outside setup(); ATSTART + ATEND + ATPATH rels are
  rarely more than a handful). Per-frame, iterates _iter_path_connections,
  positions one billboarded icon at each join via
  tool.Wall.path_connection_location_world, and hides the rest. Each
  visible icon's bound operator carries the partner GlobalId, so a
  click removes only that one rel.
* model/__init__.py: register both classes alphabetically.

Mutually exclusive with GizmoWallJoinIntersection via poll() — that
group requires len(selected) == 2; this one requires 1.

Gorgious56 db94877d8b Add wall path-connection inverse-walk helpers
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.

Gorgious56 8e93fde930 Add wall draft-resync helper + wire 6 mutation operators
After a one-shot wall IFC mutation (unjoin / split / merge / extend /
join-at-corner …) the always-visible gizmos on the OTHER side of the
join can be left reading stale ``BIMWallProperties`` — the IFC
geometry moved but the draft props that drive the gizmo handles still
point at the pre-mutation numbers, so a subsequent edit-mode enter
shows the wall at its old length / position.

* New ``_maybe_resync_wall_props_from_ifc(obj)``: re-primes a single
  wall's draft props from current IFC, with guards for non-walls,
  non-parametric walls, and walls in an active draft session (the
  draft is then the source of truth, not IFC). Must run from an
  operator ``_execute`` — ID writes from gizmo refresh raise.
* New ``_resync_walls_after_mutation(objs)``: iterates the above
  across a selection.
* Six existing mutation operators gain a resync call after their
  ``core.*`` / ``DumbWallJoiner`` mutation completes:
  UnjoinWalls, ExtendWallsToUnderside, ExtendWallsToWall, SplitWall,
  MergeWall, JoinWallsIntersection. MergeWall resyncs only the
  surviving wall — the active wall is the deletion target.

Gorgious56 f28b901a49 Fix parametric framework live-session regressions
Bundle of bugs surfaced when exercising the new gizmo framework
end-to-end in a live Blender session after the
bim/module/drawing/gizmos.py refactor + TypeAccessor/CycleType/PickType
mixins landed.

Register / annotation resolution
* parametric_lifecycle.py: hoist `entity_instance` import out of
  TYPE_CHECKING so typing.get_type_hints resolves the
  Callable[[entity_instance], bool] annotation at operator registration
  (CycleDoorType, CycleWindowType, CycleStairType failed with NameError).
  Clarify the INTERFACE return contract on the picker entry-point so
  readers see why the gizmo step stays off the undo stack.

Framework callable contracts
* model/wall.py, door.py, window.py, stair.py: migrate `props_getter`
  and `element_checker` from bl_idname strings to bound classmethods
  on tool.Model / tool.Parametric. BaseParametricGizmoGroup.get_props
  expects a callable; the string form raised TypeError on first
  gizmo poll.
* model/door.py, model/stair.py: drop the dead `prop_path=` operator
  kwarg from create_arc_gizmo / create_icon_gizmo call sites. The
  framework helper blindly setattrs every kwarg onto the operator's
  OperatorProperties, but ToggleDoorSwing / ToggleStairProperty don't
  declare prop_path — the setattr raised mid-setup_element_specific_gizmos,
  so self.gizmo_door_type / self.lock_gizmo never got assigned and
  every subsequent draw_prepare tornadoed AttributeError. Nothing
  reads op.prop_path anywhere; the kwarg was dead data.

Dispatcher operators
* model/array.py: add EnableEditingParametric (the framework pen-icon
  dispatcher that routes to a per-feature edit operator by bl_idname
  string) and AddArrayFromFeatureEdit (binds the framework's array
  icon to bim.add_array on the current parametric draft).
* model/__init__.py: register both new operators.

Per-frame robustness
* drawing/gizmos.py: guard BaseParametricGizmoGroup.draw_prepare with
  is_setup_complete() — matches the existing guard in refresh() and
  in BaseSchematicGizmoGroup.draw_prepare(). Defense-in-depth: when
  any subclass's setup raises mid-way, draw_prepare now no-ops cleanly
  instead of per-frame AttributeError-tornadoing on whatever attribute
  the failed setup phase was meant to populate.
* model/decorator.py: guard ProfileDecorator.__call__ against
  context.active_object is None. The decorator is a per-frame
  viewport draw handler; deselecting or deleting the active object
  while it's installed crashed on obj.mode access. Treat None the
  same as "no longer in edit mode" — uninstall + fire the exit
  callback if present.
* geometry/data.py: ViewportData.load() populates `data` before
  flipping `is_loaded`, so a raise from cls.mode() no longer leaves
  the class flag-set but data-empty for subsequent reads.

Gorgious56 1b272c039d Refactor bim/module/drawing/gizmos — framework + icon infra
Three concerns bundled into one cohesive refactor of gizmos.py
(splitting them surgically requires intermediate commits with
duplicate same-named classes that Python can't parse):

1. Framework primitives — StaticTrisGizmoMixin + TexturedQuadGizmoMixin
   replace the older TrisGizmoMixin. New module-level helpers:
   _get_static_tris_shader / _get_static_tris_batch / clear_static_
   tris_cache for cached GPU batch reuse, _draw_outline_and_body for
   the shared outline-then-body render path, draw_tris_with_outline
   as the public wrapper. billboarded_at(world_pos, billboard_rot,
   scale) is the canonical billboard-matrix helper; should_flip_extend_
   arrow encapsulates the view-aware mirror decision for extend
   gizmos; get_warning_color_from_prefs reads the user's warning
   color.

2. Config classes — BaseValueGizmoConfig (shared visibility + dimension-
   text contract), CountGizmoConfig (array N indicator),
   DimensionGizmoConfig (length / height / depth labels), IconActionConfig
   (icon-only gizmos that invoke an operator on click). DimensionRenderer
   draws the actual numeric label using BLF.

3. Icon classes — each rewritten on StaticTrisGizmoMixin so they share
   the cached GPU batch + outline-then-body render path:
   GizmoLockOpen / GizmoLockClosed (replacing the single-state
   GizmoLock), GizmoArc, GizmoFillet, GizmoWallCornerIcon,
   GizmoWallTeeIcon, GizmoPen / GizmoValidate / GizmoCancel (the
   parametric-edit triad), GizmoPlus / GizmoMinus / GizmoTrash,
   GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator (array
   context indicators with a small digit-rendering helper for the "xN"
   count label), GizmoMerge / GizmoSplit / GizmoUnjoin (wall-join
   icons), and GizmoMenu (textured-quad icon-action menu trigger).

The legacy TrisGizmoMixin, GizmoLock, and DimensionDrawConfig are
removed; downstream callers in subsequent PR4 commits swap to the
new mixin and config classes when their feature operators land.

CycleTypeMixin / PickTypeMixin / TypeAccessorBase live in
bim.parametric_lifecycle (previous commit). The three mixins are
re-exported from gizmos.py here so feature-module access via
``gizmo.<MixinName>`` keeps working until PR5 cleanup drops the
re-exports.

bim/module/drawing/__init__.py is updated in the same commit to
register the 11 new gizmo classes (GizmoLockOpen / GizmoLockClosed /
GizmoFillet / GizmoWallCornerIcon / GizmoWallTeeIcon / GizmoTrash /
GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator /
GizmoUnjoin / GizmoMenu) — without that, the new classes exist in
gizmos.py but aren't usable as bpy gizmo types.
