+"""Generic face-quad resize gizmos for any axis-aligned local box.
+
+This module contains the box-agnostic core of the interactive
+face-resize gizmos: two Gizmo classes (a near-invisible click target
+welded to each face, and a thin colored edge outline), a per-redraw
+orchestrator that places six of each on a box, and the pure one-sided
+resize arithmetic. None of it knows about IFC, clip boxes, or
+``BIMSceneClipBoxProperties`` — a future camera-view-box adapter can
+reuse the same classes and helpers.
+
+Consumer contract — the adapter group must:
+
+1. Create six ``BIM_GT_box_face_quad`` and six ``BIM_GT_box_face_outline``
+ instances at ``setup()`` time, in :data:`FACE_ROUTES` order, and bind
+ each quad's ``move_get_cb`` / ``move_set_cb`` to closures that read
+ and mutate the box's host (e.g. an Empty's ``location`` / ``scale``).
+2. Call :func:`apply_face_quad_layout` from ``refresh()`` /
+ ``draw_prepare()`` with the box's local-frame ``bmin`` / ``bmax``,
+ the host's ``matrix_world``, the OBB rotation as a 4x4
+ (``Matrix.Identity(4)`` when the rotation rides in ``matrix_world``),
+ and the current ``region`` / ``rv3d``.
+3. Implement ``_lock_for(active_gz)`` / ``_unlock_all()`` on the group
+ for drag mutual exclusion; the quad's ``invoke`` / ``exit`` call them.
+
+The resize arithmetic in :func:`compute_face_resize` is pure: feed it
+the modal scalar plus drag-start snapshots and it returns the host's
+new scale-on-axis and new origin location.

+"""Shared post-disconnect cleanup dispatch.
+
+Used by both ``bim.disconnect_elements`` (explicit user disconnect) and the
+connection cascade in ``tool.Geometry.delete_ifc_object`` (implicit
+disconnect-on-delete). Each kind returned by
+:py:meth:`bonsai.tool.connection.Connection.find_rels` /
+:py:meth:`find_rels_for_element` maps to a single arm here, so adding a new
+kind means extending one dispatch table — both call sites benefit
+automatically and the AST forward-compat guard enforces coverage.
+
+The ``subject`` parameter is the entity whose teardown effects the
+disconnect: for ``"path"`` / ``"element"`` / ``"element-top"`` kinds it
+carries an ``IfcRel*`` relationship entity (the rel that gets removed);
+for ``"mep-pair-fitting"`` it carries an ``IfcFlowFitting`` (the fitting
+that gets deleted). The slot is uniform on intent — the dispatch decides
+the teardown mechanism by kind.

+
+- ``"path"`` — ``IfcRelConnectsPathElements`` (wall-wall, wall-roof, etc.).
+ ``subject`` is the rel; removing it disconnects.
+- ``"element-top"`` — ``IfcRelConnectsElements`` with ``Description=="TOP"``
+ (created by ``extend_walls_to_underside``). ``subject`` is the rel.
+- ``"element"`` — any other ``IfcRelConnectsElements``. ``subject`` is the rel.
+- ``"mep-pair-fitting"`` — two MEP elements joined via ``IfcRelConnectsPorts``
+ through a single bridging ``IfcFlowFitting``. ``subject`` is the fitting
+ itself; removing it disconnects. ``OBSTRUCTION`` fittings are excluded
+ here; those go through ``bim.mep_add_obstruction(mode=REMOVE)``.
+
+Add new kinds by extending :py:meth:`Connection.find_rels`. The dispatch in

+"""Contract test for BIM_OT_assign_type's per-object class-compatibility
+partition.
+
+When the user multi-selects mixed classes (e.g. a wall + a door), the panel
+picker filters the class dropdown by the active object's class only.
+Historically the operator then fanned out across the whole selection without
+re-checking each occurrence, producing schema-corrupt IFC files (IfcDoor
+typed by IfcWallType). The partition added in this change must:
+
+1. Assign the type only to compatible occurrences.
+2. Surface skipped classes through ``self.report({'WARNING'}, ...)``.
+3. ``return {'CANCELLED'}`` and emit an ERROR when nothing in the selection

+
+The opening/void/array recut paths fan out N host-mesh rebuilds per array of N
+fillings — the CSG opening-subtraction inside ``switch_representation`` is the
+most expensive geometry step in the addon. ``batch_host_recut`` queues
+``recut_host`` + ``update_host_representation`` calls by voided element id and
+drains each unique host once on the outermost exit. These tests pin the
+queue/depth/drain contract that the call-site rewrites in subsequent phases
+rely on."""
