 """Headless test: connectors follow moved features across ALL assemblies.
 Simulates the test-file scenario: a plate with a hole, mated hole-to-face
 in two different assemblies.  The hole is moved (rebuilt geometry) and the
 body-update connector recalculation must:
  1. re-locate the hole connector on every instance of the component
     (both the active and a non-active assembly),
  2. re-solve each mated pair so the partner parts follow,
  3. never snap a planar connector onto the cylindrical hole (type match),
  4. mark a connector invalid when its feature disappears.
  5. auto-follow a FAR move when the candidate is unambiguous (single
     feature of its class) — the demo case,
  6. NOT auto-apply an ambiguous far candidate (another same-class feature
     is nearer) — that needs a manual pick, simulated here.
  7. backfill legacy connectors' entity_type from their auto-generated name.

 python -c "from fluency.geometry_occ.sketch import OCCSketch; ..."
 ```
 ---
 ## Code Conventions
 ### General
 - Line length: **100 chars** (black/ruff config)
 - Target Python: **3.10+** (uses `from __future__ import annotations`, walrus, pattern matching)
 - Docstrings: Google/NumPy style preferred
 - Logging: `logger = logging.getLogger(__name__)` with `logging.DEBUG` level
 ### OCC / OCP
 - Always use `is not None` for OCP objects — `TopoDS_Shape.__bool__` can be falsy even for valid shapes
 - `BRepBuilderAPI_MakeFace.Add(wire)` expects a `TopoDS_Wire`. `wire.Reversed()` returns `TopoDS_Shape` → cast via `_TopoDS.Wire_s(wire.Reversed())`
 - Face normal direction: check `face.Orientation()` vs `TopAbs_REVERSED` — a REVERSED face's outward normal is the NEGATION of the surface axis
 - `TopoDS_Wire_s(shape)`, `TopoDS_Face_s(shape)` — use `_s` suffix from OCP for downcasts
 - Mesh: `BRepMesh_IncrementalMesh(shape, tol, False, 0.15, True)` — default deflection 0.15 rad for smooth curves
 ### Extrude / Cut Workflow
 - Snapshot `list(self._current_component.bodies.items())` **BEFORE** `add_body()` — the new body must not be in the target set
 - Cut targets the **source body** (`sketch._source_body_id` from face pick), not `bodies[0]`
 - The fix: apply boolean to **target** geometry, then remove tool body
 - Plain extrude with holes: inner wires must have **OPPOSITE** geometric winding to the outer wire (see `build_face_geometry` and `_loop_signed_area`)
 ### Sketch / Solvers
 - `python_solvespace` has NO remove API for entities/constraints. Deleting requires: drop from `_points`/`_lines`, prune `_constraint_log`, `_rebuild_solver()` (recreates entire system), `_rebuild_labels()`, re-solve
 - `_constraint_log`: each entry is `{"type": str, "ids": tuple[int,...], "params": tuple, "labels": set[str]}`
 - Constraint labels: stored on **point** entities for paintEvent rendering; rebuilt via `_rebuild_labels()`
 - Line constraints (`horizontal`/`vertical`/`parallel`/`perpendicular`) need the **line's** solver handle, not a point's. Use `_find_line_sketch_entity()` to get the correct handle
 - External entities (underlay): `is_external=True`, `is_construction=True`, fixed in solver (always `dragged`). Stored in `_external_entity_ids`, excluded from `_line_segments()`, `get_polygon_points()`, `get_closed_loops()`, `detect_faces()`, `get_geometry()`
 ### Face Detection
 - `get_closed_loops()`: uses snapped-coordinate graph (`_SNAP_TOL = 1e-4`) from line endpoint adjacency. Only accepts simple cycles (all nodes degree 2)
 - `detect_faces()`: even-odd nesting rule via `_loop_contains`. Even depth = outer boundary, odd = hole
 - `_loop_rep_point`: midpoint between centroid and first vertex. **Fragile** — can land inside a nested shape for certain geometries (e.g., a small hole near the centroid's direction from the first vertex)
 - `_loop_signed_area`: shoelace formula for polygons, `πr²` (positive = CCW) for circles
 ### Rendering
 - **OCCRenderer** is the main renderer (not pygfx). Uses `AIS_Shape`, `V3d_Viewer`, `AIS_InteractiveContext`
 - Face pick: `pick_planar_face(x, y)` → `MoveTo` → `DetectedShape` → `TopoDS_Face_s` → `BRepAdaptor_Surface` plane check
 - Highlight: `highlight_face(face)` creates a transparent AIS overlay; `clear_face_highlight()` removes it
 - Preview: `preview_shape(shape)` for live transparent extrude preview
 - Navigation: Left=orbit, Middle=pan, Wheel=zoom. **Right is RESERVED** — check user before reassigning
 ### Paint-Event Safety
 - Every constraint-tag rendering loop wraps each entry in `try/except` so a bad entry (dangling id, corrupted geometry) doesn't crash the entire paint event
 - `_point_world()` and `_entity_anchor()` return `None` (not raise) for malformed input
 ---
 ## Known Bugs & Fix Patterns
 ### 1. Hole Orientation in Extrusion (FIXED 2026-07-03)
 **Symptom**: Inner shapes (circle/triangle/slot) inside a rectangle become solid islands instead of holes when extruding, depending on drag direction.
 **Root Cause**: `wire_loop` in `build_face_geometry` unconditionally reversed hole wires (`w.Reversed()`). When the outer polygon was CW-winding (e.g., dragging from top-left to bottom-right), the reversed inner had the SAME effective direction as the outer, making OCC treat it as solid.
 **Fix**: Added `_loop_signed_area()` to compute geometric winding. Hole wires are only reversed when their natural winding matches the outer's (ensuring opposite winding for holes).
 **Relevant code**: `sketch.py`, `build_face_geometry()` and `_loop_signed_area()`
 ### 2. _loop_rep_point Fragility (KNOWN)
 **Symptom**: Face detection fails when a nested shape contains the outer loop's representative point (midpoint between centroid and first vertex).
 **Would-be fix**: Use a guaranteed-interior point (maximum inscribed circle center or perturbed centroid) instead of the centroid-first-vertex midpoint.
 ### 3. Extrude Cut / Target Selection (FIXED 2026-06-29)
 **Symptom**: Cut created a separate "cavity-shaped" body next to the original instead of modifying the target.
 **Fix**: Boolean result stored on TARGET body geometry; tool body removed from component. Auto-target via `sketch._source_body_id`.
 ### 4. Workplane Preservation (FIXED 2026-06-29)
 **Symptom**: Sketch placed on a face lost its workplane after being added to component.
 **Fix**: Copy `occ_sketch` workplane fields into `Sketch` dataclass BEFORE `apply_workplane()`.

 ## API Quirks
 - **`QPoint(0,0)`**: falsy via `isNull()` in PySide6 → always use `is not None` for `Optional[QPoint]`
 - **`QMouseEvent`/`QPainterPath`**: live in `PySide6.QtGui` (NOT `QtCore`)
 - **`BRepBuilderAPI_MakeFace.Add()`**: needs `TopoDS_Wire`. `wire.Reversed()` returns `TopoDS_Shape` — cast via `TopoDS_Wire_s()`
 - **python_solvespace**: NO entity/constraint remove API — workaround via `_rebuild_solver()`. Parameters read via `solver.params(handle.params)` → returns `(x, y)` tuple
 - **OCGeometryKernel.extrude**: unwraps `OCCGeometryObject`, raw `TopoDS_Shape`, or cadquery `Workplane`. Always use `is not None` for the shape (not truthiness)
 - **Sketch._source_body_id**: dynamic attribute set on `Sketch` dataclass, set during face-pick flow
 - **`_get_shape(obj)`**: returns `obj.shape.wrapped` for `OCCGeometryObject`, `obj.shape` for raw shapes, `None` for empty. Use `is not None` guards everywhere

 ## Memory / Agent Context
 This project has extensive Pi memory (hermes-memory) for:
 - `project="fluency"` with `target="failure"`: bugs, fixes, corrections, insights
 - `project="fluency"` with `target="memory"`: conventions, decisions, workflow patterns
 - Available skills: `fix-cad-app-pipeline`, `refactor-from-cadquery-to-ocp`
 Key memory queries for debugging:
 - "hole orientation" → `_loop_signed_area` / `build_face_geometry` fix
 - "extrude cut auto-target" → cut/target body fix
 - "workplane preservation" → _add_sketch_to_component fix
 - "_loop_rep_point" → face detection fragility
 - "paint-event safety" → try/except per entry pattern
 - "solver rebuild" → delete workflow via _rebuild_solver
 - "face pick origin" → pick_planar_face face bbox centre

 ## Testing Patterns
 ```python
 # Direct OCC test (no Qt)
 from OCP.BRepBuilderAPI import BRepBuilderAPI_MakePolygon, BRepBuilderAPI_MakeFace
 from OCP.gp import gp_Pnt
 from OCP.BRepPrimAPI import BRepPrimAPI_MakePrism
 from OCP.GProp import GProp_GProps; from OCP.BRepGProp import BRepGProp
 # Build test shape, extrude, verify volume
 mp = BRepBuilderAPI_MakePolygon(); ...
 g = GProp_GProps(); BRepGProp.VolumeProperties_s(shape, g)
 assert abs(g.Mass() - expected) < 0.1
 ```
 ```python
 # Sketch-based test
 from fluency.geometry_occ.sketch import OCCSketch
 from fluency.geometry_occ.kernel import OCGeometryKernel
 sk = OCCSketch()
 # ... add points, lines, circles ...
 sk.solve()
 geom = sk.get_geometry()
 solid = OCGeometryKernel().extrude(geom, 10.0)

 # Realistic Render View — Implementation Plan
 ## Context
 Add a **"Render"** feature to Fluency CAD that opens a separate window for photorealistic rendering of the selected component or assembly (like KeyShot/Cacles).
 **Constraints:**
 - Open in a **new window** — don't clutter the workspace
 - **Keep existing OCCRenderer** for the interactive 3D viewport — untouched
 - Render backend must be a **separate, swappable module** so we can change the renderer later
 - Use **Mitsuba 3** as the initial backend (`pip install mitsuba`, ~50MB)
 ---

 ### Swappable Backend Interface
 ```python
 from abc import ABC, abstractmethod
 from dataclasses import dataclass
 import numpy as np
@dataclass
 class RenderMaterial:
    name: str
    color: tuple[float, float, float] = (0.7, 0.7, 0.7)
    metallic: float = 0.0        # 0.0–1.0
    roughness: float = 0.5       # 0.0–1.0
    bsdf_type: str = "diffuse"   # diffuse | roughconductor | roughdielectric | plastic
@dataclass
 class RenderCamera:

 Switching backends later = write a new class implementing `RenderBackend`. One import change.

 ## Mitsuba 3 Backend
 ### Why Mitsuba
 | Feature | Status |
 |---------|--------|
 | `pip install mitsuba` | Single install, no system deps |
 | True path tracing | GI, caustics, spectral rendering |
 | PBR materials | `roughconductor`, `roughdielectric`, `diffuse`, `plastic` |
 | Python dict API | Build scenes programmatically, no XML |
 | CPU + GPU backends | `scalar_rgb` (CPU), `cuda_rgb` (NVIDIA) |
 | Output formats | PNG, EXR (HDR) with tonemapping |
 ### OCC → OBJ Conversion Path
 ```python
 from OCP.BRepMesh import BRepMesh_IncrementalMesh
 from OCP.StlAPI import StlAPI_Writer
 from OCP.BRep import BRep_Builder
 import tempfile, os
 def occ_shape_to_obj(shape, obj_path: str, linear_deflection: float = 0.1):
    """Tessellate OCC shape and write as OBJ for Mitsuba."""
    tess = BRepMesh_IncrementalMesh(shape, linear_deflection, False, 0.5, True)
    tess.Perform()
    # Write STL (reliable), then convert to OBJ via trimesh or direct
    writer = StlAPI_Writer()
    writer.SetASCIIMode(False)
    stl_path = obj_path.replace(".obj", ".stl")
    writer.Write(shape, stl_path)
    # Mitsuba can read STL directly, or we convert to OBJ
    return stl_path
 ```
 ### Mitsuba Scene Construction
 ```python
 import mitsuba as mi
 mi.set_variant("scalar_rgb")
 def build_scene(mesh_path: str, material: RenderMaterial,
                camera: RenderCamera, settings: RenderSettings) -> mi.Scene:
    # Map our material to Mitsuba BSDF
    bsdf_map = {
        "diffuse": {"type": "diffuse", "reflectance": {"type": "rgb", "value": material.color}},
        "roughconductor": {
            "type": "roughconductor",
            "material": "copper",  # or铝, 钢, etc.
            "alpha": material.roughness,
        },
        "roughdielectric": {
            "type": "roughdielectric",
            "int_ior": 1.5,
            "alpha": material.roughness,
        },
        "plastic": {
            "type": "plastic",
            "diffuse_reflectance": {"type": "rgb", "value": material.color},
            "int_ior": 1.5,
        },
    }
    return mi.load_dict({
        "type": "scene",
        "integrator": {"type": "path", "max_depth": settings.max_depth},
        "sensor": {
            "type": "perspective",
            "fov": camera.fov,
            "to_world": mi.ScalarTransform4f.look_at(
                origin=camera.origin, target=camera.target, up=camera.up
            ),
            "film": {"type": "hdrfilm", "width": settings.width, "height": settings.height},
            "sampler": {"type": "independent", "sample_count": settings.spp},
        },
        "emitter": {"type": "constant"},
        "shape": {
            "type": "stl",  # or "obj"
            "filename": mesh_path,
            "bsdf": bsdf_map.get(material.bsdf_type, bsdf_map["diffuse"]),
        },
    })
 ```

 ## Material Presets
 | Preset | Color | Metallic | Roughness | BSDF |
 |--------|-------|----------|-----------|------|
 | Brushed Steel | (0.65, 0.67, 0.72) | 0.9 | 0.35 | roughconductor |
 | Polished Chrome | (0.8, 0.8, 0.8) | 1.0 | 0.05 | roughconductor |

 | Copper | (0.95, 0.64, 0.54) | 0.95 | 0.15 | roughconductor |
 | Gold | (1.0, 0.76, 0.33) | 1.0 | 0.1 | roughconductor |
 | Blackened Steel | (0.15, 0.15, 0.17) | 0.8 | 0.4 | roughconductor |
 | Matte Plastic | (0.2, 0.5, 0.8) | 0.0 | 0.6 | plastic |
 | Glossy Plastic | (0.2, 0.5, 0.8) | 0.0 | 0.1 | plastic |
 | White Nylon | (0.85, 0.85, 0.83) | 0.0 | 0.45 | plastic |
 | Black ABS | (0.05, 0.05, 0.05) | 0.0 | 0.35 | plastic |
 | Red PA12 | (0.75, 0.08, 0.08) | 0.0 | 0.4 | plastic |
 | Rubber | (0.1, 0.1, 0.1) | 0.0 | 0.9 | diffuse |
 | Ceramic White | (0.92, 0.91, 0.88) | 0.0 | 0.15 | dielectric |
 | Glass | (0.95, 0.95, 0.95) | 0.0 | 0.0 | dielectric |
 | Wood | (0.6, 0.4, 0.2) | 0.0 | 0.7 | diffuse |
 **Note:** Mitsuba pip installs don't include spectral metal data files (iron.spd, copper.spd, etc.), so metal presets use `material="none"` with `specular_reflectance` set to the metal color instead.
 ---
 ## Risks & Mitigations
 | Risk | Mitigation |
 |------|-----------|
 | Mitsuba not installed | Graceful error: "pip install mitsuba" shown in UI |
 | Slow CPU rendering | Default to low SPP (64) for preview; offer GPU variant if CUDA available |
 | Large meshes slow to tessellate | Progress indicator; optional mesh decimation |
 | Mitsuba STL/OCC compatibility | Test tessellation quality; tune `linear_deflection` |
 ---
 ## Estimated Effort
 - **Phase 1** (abstract backend + OCC→mesh + Mitsuba impl): ~4-6 hours
 - **Phase 2** (render window UI + material presets): ~3-4 hours
 - **Phase 3** (polish, export, swap test): ~2-3 hours
 - **Total**: ~9-13 hours
