When re-generating a production or geometry GLB, the old approach deleted the
existing MediaAsset record and created a new one with a new UUID. Any page that
had the old download_url (/api/media/{old-id}/download) cached would then get
a 404 when trying to download, because the asset ID no longer existed in the DB.
Fix: update the existing MediaAsset record in-place (same UUID, new storage_key)
so existing download URLs remain valid after regeneration. Create a new record
only if no existing one is found.
Applies to both generate_gltf_geometry_task and generate_gltf_production_task.

- Per-tenant Azure AI config stored in tenants.tenant_config JSONB
- GET/PUT /api/tenants/{id}/ai-config + POST .../test connection
- api_key never returned to frontend (has_api_key: bool pattern)
- azure_ai.py resolves creds from tenant config when ai_enabled=True
- ai_tasks.py loads tenant config and passes it to validate_thumbnail
- Admin GPU Status section: probe button + status badge + last-checked time
- Notifications: _BELL_CHANNELS filter (notification+alert only in bell)
- Tenants.tsx: per-row Azure AI Config modal with URL auto-parse helper
- Remove duplicate in-memory /gpu-probe endpoints (kept DB-backed /probe/gpu)

- GET /api/workflows/pipeline-steps: returns all StepName enum values
with category (input|processing|rendering|output) + descriptions;
registered before /{workflow_id} to avoid path collision
- frontend/src/api/workflows.ts: getPipelineSteps(), PipelineStep
and PipelineStepsResponse interfaces
- WorkflowEditor: PipelineStepsPanel showing steps grouped by category
with collapsible accordion sections
- ConfigSidepanel: "Pipeline Step" select dropdown binds any node to a
StepName; selected step description shown below dropdown
- Active workflow indicator: green dot next to is_active=true entries
- Improved empty state with descriptive copy

Phase 5.1 — MATERIAL_PALETTE removal:
- Remove MATERIAL_PALETTE + _material_to_color() from step_processor.py
- build_part_colors() now returns {part→material_name} for Blender resolver
Phase 6 — Notification Center Refactor:
- Migration 051: add channel (activity|notification|alert) to audit_log,
add frequency (immediate|daily|never) to notification_configs
- Three notification channels: activity (per-render), notification (batch
order summaries), alert (admin infrastructure)
- Per-render emit_notification_sync calls demoted to channel=activity
- New emit_batch_render_notification_sync(): single summary notification
when all order lines reach terminal state ("47/50 succeeded, 3 failed")
- Beat task batch_render_notifications every 60s: safety-net for missed
batch notifications after order completion
- GET /notifications: defaults to channel IN (notification, alert);
accepts ?channel=activity for activity feed
- Unread count badge counts only notification+alert channels
- Notifications.tsx: three tabs (Notifications | Activity | Alerts)
- NotificationSettings.tsx: frequency dropdown per event type

Phase 2.3 — Fix render cancellation (real Celery task ID):
- orders.py cancel endpoints: read celery_task_id from render_job_doc
instead of synthetic "render-{line_id}" which was a no-op
- render_order_line_still_task: creates RenderJobDocument at task start,
stores self.request.id as celery_task_id, writes step-level state
(RESOLVE_STEP_PATH → BLENDER_STILL) back to order_lines.render_job_doc
Phase 3.1 — Remove Pillow overlay dead code:
- blender_render.py: deleted 55-line Pillow post-processing block
(lines 798-851, green bar + model name label)
- transparent_bg=True is always passed; the else branch was unreachable
- Removed mention from script docstring

Phase 1 of PLAN_REFACTOR.md — all four sub-tasks implemented:
1.1 PipelineLogger (backend/app/core/pipeline_logger.py)
- Structured step_start/step_done/step_error/step_progress API
- Publishes to Python logging AND Redis SSE via log_task_event
- Context manager `pl.step("name")` for auto-timing
1.2 RenderJobDocument (backend/app/domains/rendering/job_document.py)
- Pydantic JSONB schema: state machine + per-step records + timing
- begin_step/finish_step/fail_step/skip_step helpers
- Migration 048: adds render_job_doc JSONB column to order_lines
- OrderLine model updated with render_job_doc field
1.3 TenantContextMiddleware (backend/app/core/middleware.py)
- Decodes JWT, stores tenant_id + role in request.state
- get_db updated to auto-apply RLS SET LOCAL from request.state
- Registered in main.py (runs before every request)
- JWT now embeds tenant_id claim via create_access_token()
- Login endpoint passes tenant_id to token creation
1.4 ProcessStep Registry (backend/app/core/process_steps.py)
- StepName StrEnum with all 20 pipeline step names
- Single source of truth for log prefixes, DB records, UI labels
Also adds db_utils.py with set_tenant_sync() + get_sync_session()
for use inside Celery tasks (bypass-safe RLS helper).

- 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

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.

Previously the cache_service was only used in the generate_stl_cache Celery task.
All render paths (render_still, render_turntable_to_file, render_turntable_task)
only checked for a local file and converted from scratch if missing.
Changes:
- render_blender.py: add _stl_from_cache_or_convert() helper that checks MinIO
cache before falling back to local STEP→STL conversion. Wire into render_still()
and render_turntable_to_file() (both STL conversion blocks).
- domains/rendering/tasks.py: wire MinIO cache check into render_turntable_task()
inline before convert_step_to_stl(). All errors are non-fatal (falls back to
fresh conversion).
Now a STEP file converted on one worker is available to all workers via MinIO,
avoiding redundant cadquery conversions on re-renders.

storage.upload() expects Path, not str — str has no .name attribute,
causing 'str object has no attribute name' warnings on every STL cache write.

- fix(tasks): @shared_task → @celery_app.task so task uses configured redis://redis broker
(@shared_task without explicit app bound to default app → localhost:6379 → Connection refused)
- fix(tasks): import app.models before DB access so SQLAlchemy can resolve Material.creator → User
relationship (was: InvalidRequestError: 'User' failed to locate a name)
Verified: catalog refresh now finds and stores 35 materials from uploaded .blend file.

- fix(tasks): use RENDER_SCRIPTS_DIR env var for catalog_assets.py path
(was computing wrong path via __file__ parents → /render-worker/scripts/ which doesn't exist in container)
- fix(models): add AssetLibrary to app/models/__init__.py so alembic autogenerate discovers it
- fix(api): remove unused FileResponse import from asset_libraries.py

Change list/create route paths from '/' to '' on workflow_router so
GET /api/workflows and POST /api/workflows respond directly without
307 redirect. The redirect was causing axios to drop the Authorization
header, making the WorkflowEditor always show an empty list.

Migration 039: cad_files.mesh_attributes JSONB column.
domains/products/tasks.py: extract_mesh_attributes Celery task using pythonOCC.
still_render.py + turntable_render.py: _apply_mesh_attributes() sets auto-smooth
based on curved_ratio and topology threshold from OCC analysis.
render_blender.py: passes --mesh-attributes JSON arg to Blender subprocess.
render_still_task: loads mesh_attributes from DB and passes to renderer.

Migration 035: tenants table with 'Schaeffler' default seed.
Migration 036: tenant_id FK on all tables, RLS policies, backfill.
New domains/tenants/ with CRUD router (admin only).
All domain models extended with tenant_id FK.
core/database.py: get_db_for_tenant with RLS context setter.
