- @timed_step decorator with wall-clock + RSS tracking (pipeline_logger)
- Blender timing laps for sharp edges and material assignment
- MeshRegistry pattern: eliminate 13 scene.traverse() calls across viewers
- Lazy material cloning (clone-on-first-write in both viewers)
- _pipeline_session context manager: 7 create_engine() → 2 in render_thumbnail
- KD-tree spatial pre-filter for sharp edge marking (bbox-based pruning)
- Batch material library append: N bpy.ops.wm.append → single bpy.data.libraries.load
- GMSH single-session batching: compound all solids into one tessellation call
- Validate part-materials save endpoints against parsed_objects (prevents bogus keys)
- ROADMAP updated with completion status

Extract Base Color, Metallic, Roughness, Transmission, IOR from Blender
asset library materials via catalog_assets.py. Store in catalog JSON and
serve via /api/asset-libraries/pbr-map endpoint. Frontend viewers apply
PBR properties to Three.js MeshStandardMaterial using hex color strings
(avoiding Three.js ColorManagement sRGB/linear issues).
Key fixes:
- RLS bypass for material alias lookup in pbr-map endpoint
- pbrMap empty guard prevents premature grey fallback in viewers
- Cache-Control: no-cache on pbr-map requests to avoid stale data

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.
Updated all references in: task decorators, celery_app.py, beat_tasks.py,
docker-compose.yml worker command, worker.py MONITORED_QUEUES, admin.py,
CLAUDE.md, LEARNINGS.md, Dockerfile, helpTexts.ts, test files,

- 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

Render pipeline:
- Replace per-object _apply_smooth() loop with _apply_smooth_batch(): selects
all 175 parts, calls shade_smooth_by_angle() ONCE in C → reduces 16s to ~0.2s
- Remove 175 per-part "assigned material to part" log lines (replace with summary)
- Add TIMING_SUMMARY log line at end of every render showing all step durations
- _lap() helper records split times for: template_load, glb_import, rotation,
smooth_shading, material_assign, pre_render_setup, gpu_render
Frontend role checks:
- Add global_admin + tenant_admin to User role type in auth store
- Add isAdmin() and isPrivileged() helper functions
- Fix Admin.tsx, Layout.tsx, Notifications.tsx, OrderDetail.tsx, ProductDetail.tsx,
CostOverviewWidget.tsx — all were checking role === 'admin' but JWT now has
role === 'global_admin' after migration 049 (admin → global_admin backfill)
- This caused Admin page to render completely empty

- GPU: fix Cycles device activation order — set compute_device_type
BEFORE engine init, re-set AFTER open_mainfile wipes preferences
- GPU: remove _mark_sharp_and_seams edit-mode loop (redundant with
Blender 5.0 shade_smooth_by_angle), saves ~200s/render on 175 parts
- Material: fix _AFN suffix mismatch — build AF-stripped mat_map keys
and add prefix fallback in _apply_material_library (blender_render.py)
- Material: production GLB now uses get_material_library_path() which
checks active AssetLibrary instead of empty legacy system setting
- Admin: RenderTemplateTable multi-select output types (M2M frontend)
- Admin: MaterialLibraryPanel replaced with link to Asset Libraries
- UX: move Toaster to top-left to avoid dispatch button overlap
- SQLAlchemy: add .unique() to all RenderTemplate M2M collection queries
- Logging: flush=True on all Blender progress prints, stdout reconfigure

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.

InlineCadViewer: STL-derived GLBs have non-indexed geometry (unique vertex
per triangle face). computeVertexNormals() on non-indexed geometry produces
per-face normals (faceted shading). Fix: mergeVertices() first to create
shared/indexed geometry, then computeVertexNormals() averages across
adjacent faces → smooth shading. Indexed Blender GLBs are unaffected.
generate_gltf_geometry_task: asyncio.run() inside a Celery worker that
already runs asyncpg causes 'Future attached to a different loop'. Replace
async _store() with sync SQLAlchemy session (matching the rest of the task).

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.

- QueueStatusWidget + WorkerStatusWidget expected res.data to be ActivityEntry[]
but /api/worker/activity returns {cad_processing: [...], render_jobs: [...]}
→ TypeError: entries.filter is not a function → blank screen (no error boundary)
- Both widgets now use ActivityResponse interface and read data?.cad_processing
- Field names updated: id→cad_file_id, filename→original_name, status→processing_status
- AdminDashboard: fix duplicate React key in top_products table (pim_id can repeat)
→ use index suffix to guarantee unique keys

frontend/src/pages/WorkflowEditor.tsx: full React Flow editor with
custom nodes (Input/Convert/Render/FFmpeg/Output), config sidepanel,
node palette with drag-drop, new workflow dialog.
frontend/src/api/workflows.ts: workflow CRUD API client.
@xyflow/react added to package.json dependencies.
Route /workflows + sidebar link for admin+pm.
