Instead of duplicating output types for every variation (WebP vs PNG,
different resolution), keep one canonical output type and override
specific fields per order line via render_overrides JSONB.
Backend:
- render_overrides JSONB column on OrderLine (DB migration)
- Render task merges overrides with output type settings (format, width,
height, samples, engine, denoiser, transparent_bg, cycles_device)
- POST /orders/{id}/batch-render-overrides endpoint for bulk override
- PatchLineBody accepts render_overrides for per-line patching
Frontend:
- Batch render overrides section on OrderDetail: output format dropdown
(PNG/JPG/WebP) + resolution dropdown (512-4096)
- Clear button to remove overrides
MCP:
- create_order tool: accepts product_ids, output_type, render_overrides,
material_override — enables "render all products as WebP" via Claude
- set_render_overrides tool: batch override on existing orders

The queue handles far more than thumbnails: OCC tessellation, USD master
generation, GLB production, order line renders, and workflow renders.
asset_pipeline better reflects its role as the render-worker's primary queue.

- beat_tasks.py: import app.models at module level so SQLAlchemy can
resolve relationship("Template") and relationship("User") when domain
models are imported in isolation inside task functions. Fixes all
beat tasks (batch_render_notifications, recover_stuck_cad_files) that
crashed every 60s with mapper initialization error.
- _blender_materials.py: build_mat_map_lower() now adds a slug-normalized
key variant (re.sub([^a-z0-9]+, _, kl)) for each mat_map entry. OCC
part names like 'F-802007_TR4-D1-H122AG' → slug 'f_802007_tr4_d1_h122ag'
now matches USD-imported Blender objects. Existing prefix fallback
(key.startswith(part_key)) catches AF-suffix variants.
- Orders.tsx: kanban drag-to-reject implemented. submitted/processing
cards are draggable (cursor-grab). Rejected column highlights with
red ring on drag-over. Drop opens reject reason modal via createPortal.
Confirm calls rejectOrder() mutation + invalidates orders cache.

Dokumentiert drei neue Learnings aus der GE360-HF Wälzkörper-Positions-Untersuchung:
1. BRepMesh auf Compound: Triangulation in Definition-Space, Face-loc = Instance-Placement
2. IsSame() vs IsPartner() für Assembly-Instanz-Deduplizierung
3. Stale GLB-Cache maskiert Code-Fixes — nach Tessellierungs-Änderungen Cache invalidieren
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
In _extract_mesh(), BRep_Tool.Triangulation_s(face, face_loc) returns a face_loc
that already encodes the instance's full placement transform when a compound shape
is tessellated with BRepMesh_IncrementalMesh. Applying shape_trsf on top doubled
every rotation/translation, causing multiple roller elements to collapse to the same
wrong world position (e.g. Z(-75°)×2 ≡ Z(+105°)×2 mod 360° → identical positions).
Fix: use elif so shape_loc is only applied as a fallback when face_loc is identity.
Adds seam edge extraction (UV seam primvar) and improves _traverse_xcaf doc.

Bug 1 — Missing parts (mirror/repeated instances):
- id(solid.TShape()) is unreliable in OCP: each call creates a new
Python wrapper, so id() always differs even for the same TShape.
Replaced with IsSame() for correct TShape-pointer deduplication.
- TopExp_Explorer(SOLID) misses free shells/faces in assemblies.
Fix: run BRepMesh baseline on full root compound first (catches all
face types), then GMSH overrides per unique solid for better seam
topology. REVERSED solids keep BRepMesh to avoid inverted Jacobians.
Bug 2 — GLB 7× too large (21 MB vs OCC 3 MB):
- CharacteristicLengthMax = linear_deflection × 50 (was ×15)
matches OCC effective edge length on curved surfaces (~5 mm).
- MinimumCirclePoints = min(12, ...) (was min(20, ...))
- Result: GMSH 91% of OCC file size (target ≤120% ✓)
Verified on rolling bearing STEP: same 4 skipped nodes as OCC,
25 unique GMSH tessellations (IsSame deduplication), no OOM.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Per-solid iteration prevents OOM on multi-part assemblies (25-part bearing:
2.3GB RAM when processing compound → ~100MB per solid with per-solid approach)
- Fix CharacteristicLengthMax multiplier 5× → 15× and cap MinimumCirclePoints
at 20 (prevents 63-pts/circle on angular_deflection=0.1rad → 231MB → 21MB)
- Geometry task timeout 120s → 600s for large assemblies
- Production task: reuse _geometry.glb when GMSH enabled (no re-tessellation)
and cache _production_geom.glb for OCC (mtime vs STEP check)
- Viewer now prefers production GLB when available (shows correct GMSH mesh)
- GMSH OpenMP multithreading (min(cpu_count,16)) for 4.4× speedup

Sharp edges:
- OCC→Blender coordinate transform was wrong: Blender(X,Y,Z) = OCC(X×0.001, -Z×0.001, Y×0.001)
(RWGltf Z→Y-up + Blender Y→Z-up cancel to Y↔Z swap with Z negated)
- Guard against degenerate edges (idx0==idx1) to prevent bmesh ValueError
- Use obj.matrix_world @ v.co for world-space KD-tree (assembly node transforms)
Materials:
- Single-material fallback: if only 1 library material loaded, apply to all
unmatched objects (cadquery vs RWGltf part names differ, name-match covers ~2/25)
- Fix mesh data sharing: obj.data.copy() before materials.clear() to avoid
clearing shared data blocks
- Use obj.name (not id(obj)) for cross-loop tracking — Blender Python wrappers
can be recreated between iterations
Both fixes applied to export_gltf.py (production GLB) and blender_render.py (thumbnails).

4 root causes fixed:
1. export_colors=False was removed in Blender 4.x — caused every Blender
export to fail (exit 1) and always fall back to trimesh. Remove it.
Blender now runs the full pipeline: materials + sharp edges.
2. GlbModel cloned ref never reset on url change — key={glbBlobUrl} forces
React to remount GlbModel on each new blob URL, resetting the ref so
fresh geometry is always loaded.
3. glbBlobUrl not cleared before re-fetch — setGlbBlobUrl(null) added at
start of downloadUrl effect so spinner shows instead of stale mesh.
4. staleTime: 30_000 delayed picking up new MediaAsset after generation.
Changed to staleTime: 0 so invalidation always triggers immediate refetch.

Replace trimesh-only GLB export with Blender headless pipeline using
export_gltf.py. The viewer GLB and downloadable GLB now receive:
- Material substitution via the Schaeffler asset library (.blend)
- OCC-derived sharp edge data (sharp_edge_midpoints from mesh_attributes)
marked as Blender sharp edges before export
Material map is resolved via resolve_material_map() to convert aliases
(e.g. "Steel--Stahl" → "SCHAEFFLER_010101_Steel-Bare") before passing
to Blender. Old gltf_geometry MediaAsset is replaced on each run to
avoid stale records accumulating.
Trimesh kept as fallback if Blender binary unavailable.

Bug A: Media Library thumbnails were gray because <img src> cannot send
JWT auth headers. Added useAuthBlob() hook (fetch + createObjectURL) in
MediaBrowser.tsx. Also fixed publish_asset Celery task to populate
product_id + cad_file_id on MediaAsset for thumbnail fallback resolution.
Bug B: Product dimensions now shown in Product Details card with Ruler
icon and "from CAD" label when cad_mesh_attributes.dimensions_mm exists.
Bug C: Replaced 128×128 CAD thumbnail with InlineCadViewer component.
Queries gltf_geometry MediaAssets, fetches GLB via auth fetch → blob URL
→ Three.js Canvas with OrbitControls. Falls back to thumbnail + "Load 3D
Model" button. Polling when GLB generation is in progress.
Bug D: trimesh was in [cad] optional extra but Dockerfile only installed
[dev]. Changed to pip install -e ".[dev,cad]" — trimesh now available in
backend container, GLB + Colors export works.
Also added bbox extraction (STL-first numpy parsing) in render_step_thumbnail
and admin "Re-extract CAD Metadata" bulk endpoint.
