The kanban board kept showing deleted orders until manual reload.
Added qc.invalidateQueries for 'orders' and qc.removeQueries for
the deleted order's detail cache on delete success.

System prompt rewritten with explicit RULES:
- Never ask user for info you can query yourself
- "Any product" / "beliebig" → just pick one, don't ask back
- Execute immediately, no confirmation needed
- Be concise, short answers preferred
find_product_renders tool:
- No longer requires product_name or product_id
- Call with empty params → returns any recent renders
- Enables "show me any render with transparent bg"

Added find_product_renders tool to the AI agent:
- Searches completed renders by product name/ID
- Returns viewable image URLs (relative paths)
- Supports transparent_only filter
- AI formats results as Markdown images/links in chat
Frontend:
- ChatPanel ReactMarkdown renders <img> and <a> tags
- Images shown inline (max 200px height, rounded, bordered)
- Links open in new tab with accent color
System prompt updated to instruct AI to use Markdown image syntax
when showing renders:

- Fixed: from OCP.BRepGProp import BRepGProp as brepgprop (was lowercase)
- Routed reextract_rich_metadata_task to asset_pipeline queue (render-worker
has OCC/OCP installed, worker container does not)
- Backfill verified: 45/45 products updated with volume, surface area,
part count, complexity metrics
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- All httpx tool calls use real user_id instead of uuid(int=0) for
service token — fixes 401 Unauthorized on dispatch/override
- create_order auto-submits and auto-dispatches in one step
- System prompt updated: execute immediately without asking for
confirmation, respond in user's language
- Product search returns CAD dimensions (dim_x/y/z_mm)
- query_database tool description includes cad_files schema
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- search_products now returns dim_x_mm, dim_y_mm, dim_z_mm from
cad_files.mesh_attributes->'dimensions_mm'
- query_database tool description updated with cad_files schema
including mesh_attributes->'dimensions_mm' path
- AI can now answer "what's the biggest product?" using real dimensions

Frontend: Layout extracts order/product UUID from URL path and passes
to ChatPanel as contextType/contextId. When on /orders/{uuid}, the
chat knows which order you're viewing.
Backend: System prompt now loads actual entity data for the context:
- Order: order_number, status, line counts (completed/processing/failed)
- Product: name, PIM-ID, category, STEP file status
The AI understands "this order", "current product" etc. Example:
"What's the status of this order?" → agent knows you mean SA-2026-00164

When a tool like query_database fails (e.g., bad column name), the
SQLAlchemy session enters a failed transaction state. Subsequent
operations (like saving the assistant response) then also fail with
InFailedSQLTransactionError.
Fix: rollback the session in the except block of _execute_tool().
Also improved query_database tool description with correct column
names (category_key not category) to help the AI write valid SQL.

Added react-markdown to render assistant messages with proper formatting:
- **bold** text renders as bold
- Bullet/numbered lists render correctly
- Inline code renders with monospace background
- User messages stay as plain text

Frontend interface expected 'message' and 'response' but API returns
'user_message' and 'assistant_message'. Field name mismatch caused

Catch all exceptions (not just ValueError) and return meaningful
error messages from OpenAI API errors instead of generic 500.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Actionable AI assistant that uses per-tenant Azure OpenAI credentials
to execute natural language commands against the render pipeline.
Backend:
- ChatMessage model + migration (session-based conversations)
- Chat service with 10 OpenAI function-calling tools:
list_orders, search_products, create_order, dispatch_renders,
get_order_status, set_material_override, set_render_overrides,
get_render_stats, check_materials, query_database
- All tools tenant-scoped (queries filtered by tenant_id)
- Write operations use httpx to call backend API internally
- Chat API: POST /chat/messages, GET /chat/sessions, DELETE session
- Conversation history preserved in DB (last 50 messages per session)
Frontend:
- Slide-out ChatPanel (right side, w-96, animated)
- User/assistant message styling with avatars and timestamps
- Session management (new chat, session history, delete)
- Typing indicator while waiting for AI response
- Floating chat button in bottom-right corner
- Error state for unconfigured AI tenants
Example: "Render all Kugellager products as WebP at 1024x1024"
→ Agent calls search_products + create_order + dispatch_renders

Root cause: render-worker and render-worker-light shared the same GPU,
causing contention. Complex TRB renders went from 17s → 36s (2x slower).
Changes:
- Thumbnails back to asset_pipeline queue (not asset_pipeline_light)
- Dispatch routing always uses asset_pipeline (no queue splitting)
- render-worker-light gated behind "multi-gpu" profile — only starts with:
docker compose --profile multi-gpu up -d
- For single-GPU setups: all rendering is sequential on one worker
The dual queue approach is correct for multi-GPU machines where each
worker gets its own GPU. On single-GPU, serial execution is faster
than concurrent GPU contention.

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

Task 4: Dual render queue
- render-worker: heavy (asset_pipeline, concurrency=1) — HQ 2048x2048, animations
- render-worker-light: light (asset_pipeline_light, concurrency=2) — thumbnails, <=1024
- Thumbnails routed to light queue automatically
- Order line renders routed by resolution at dispatch time
Task 5: GLB caching (skip re-tessellation)
- Before tessellating, check if gltf_geometry MediaAsset exists for the cad_file_id
- If found, copy to expected path — render_blender.py finds it and skips tessellation
- Saves 7-11s per re-render of the same product
Task 6: WebP output format
- New 'webp' option in output_format (OutputType admin)
- Blender renders PNG intermediate, Pillow converts to WebP (quality=90, method=4)
- 50-70% smaller files with no visible quality loss
- Correct MIME type (image/webp) in MediaAsset

The OptiX cache was mounted at /root/.nv but NVIDIA writes to
/var/tmp/OptixCache_root/optix7cache.db (28MB). Fixed volume mount.
Before: first render after container restart = 181s (OptiX recompilation)
After: first render after container restart = 20s (cached kernels)

Added refetchInterval to the order query that polls every 3 seconds
while render_progress has pending or processing lines. Stops polling
automatically when all renders reach a terminal state (completed/failed/cancelled).
Fixes: render log and backend status not appearing until manual page reload.

Removed from UI (saved to DB but never read by any service):
- Max Concurrent Renders, Stall Timeout, Thumbnail Format, Product Thumbnail Priority
- Render Linear/Angular Deflection (only Scene deflections are used)
- GLB Scale Factor, Smooth Normals, GLB Material Mode, PBR Roughness, PBR Metallic
Fixed Blender status check:
- Old: called is_blender_available() in backend container (Blender not installed there)
- New: dispatches Celery task on asset_pipeline queue → runs in render-worker container
- Returns: available=true, version="Blender 5.0.1", binary path
- Status card moved to System Tools tab with refresh button
Kept active: engine, device, samples, smooth angle, tessellation, scene deflections,
3D viewer zoom limits

Admin tables (same pattern as OutputTypeTable):
- RenderTemplateTable: 11 cramped columns → expandable form row with grouped fields,
boolean flags consolidated into compact badges, .blend upload in proper section
- PricingTierTable: inline cell editing → expandable form with labeled fields,
shared renderEditFormGrid() for add/edit modes
- GlobalRenderPositionsPanel: tiny rotation inputs → expandable form with w-24 inputs,
proper labels, sensor_width_mm added to edit form
Page polish:
- WorkerManagement: larger scale controls (p-2 rounded-lg), wider number displays (w-12),
proper labels, more prominent Save button
- Billing: status select gets visible dropdown indicator (ChevronDown icon),
hover border to signal interactivity, larger action buttons with borders
- OrderDetail: batch override in proper card with title/description,
per-line override shows compact "+ override" link (expands on click),
active overrides show as amber badge with X to clear
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Replaced the 18-column inline cell editing with an expandable detail row:
- Display row always visible (no more disappearing content on edit)
- Edit form opens BELOW in a full-width colSpan row with accent border
- Fields organized in a 4-column grid with proper labels:
Row 1: Name, Renderer, Format, Animation
Row 2: Turntable, Background, Device, Engine
Row 3: Samples, Resolution, Pricing, Workflow
Row 4: Categories, Material Override, Sort Order, Active
Row 5: Denoising settings (6 cols, Blender only)
- Shared renderEditFormGrid() helper for both edit and add modes
- Save/Cancel buttons at bottom of form
- React.Fragment wrappers for dual-row rendering

The Preferences page had its own inline accent color section that wasn't
updated with the custom picker. Now shows:
- 5 preset swatches + separator + custom swatch with pipette icon
- Color picker + hex input appear when custom is selected
- Larger swatches (w-8 h-8) matching the page's spacious layout
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Added 'custom' accent option with color picker + hex input
- Pipette icon on the custom swatch (switches to solid when active)
- Color picker appears inline when custom is selected
- Generates hover/light variants automatically from hex (darken/lighten)
- Dark mode accent-light uses rgba for translucency
- Persisted in localStorage, applied before React hydration (no flash)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Widgets scale in with staggered delays (60ms per widget, up to 12)
- Widget hover: lift 3px + accent border glow (dark mode: accent shadow)
- Inner numbers animate up with count-up effect
- Progress bars grow from left with spring curve (800ms delay for content-first feel)
- All wrapped in prefers-reduced-motion guard

CSS-layer-only changes for zero-regression visual modernization:
- Typography: Inter font with OpenType features (cv02-cv04, cv11), tighter letter-spacing
- Dark theme: neutral zinc tones (#09090b/#18181b) replacing blue-slate (#0f172a/#1e293b)
- Borders: rgba-based for subtlety instead of solid hex colors
- Cards: rounded-xl, refined shadows with dark mode variant
- Buttons: rounded-lg, subtle lift on hover, smoother transitions (150ms ease-out)
- Badges: rounded-md (softer than full-round), tracking-wide
- Inputs: rounded-lg, ring-offset-0 for tighter focus rings
- Scrollbars: thin 6px custom scrollbars matching theme
- Selection: accent-colored text selection
- Table headers: uppercase tracking-wider for modern data table look
- Utility: fadeIn animation, subtle-pulse for loading states
No component files changed — all styling propagates via CSS variables and Tailwind config.

create_order and add_order_line endpoints were not passing
material_override from the request body to the OrderLine constructor.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Dropdown in Step 3 review to set a single material override for all lines
- Override is passed to each OrderLine.material_override at creation time
- Amber background when override is active
- Library materials loaded on Step 3 entry
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- POST /orders/{id}/batch-material-override endpoint
- Dropdown above the lines table: "Apply to all lines…"
- Options: clear all overrides, or select a library material
- Updates all order lines in one request
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add `material_override` nullable column on OrderLine (DB migration)
- Line override takes priority over OutputType override
- PATCH /orders/{id}/lines/{id} endpoint to update material_override
- Inline dropdown on each order line in the OrderDetail page
- Amber background when override is active
- Same output type, different material per line — no need to create a new output type

Both camera-orbit and object-rotation modes now parse and apply
the --material-override CLI arg, overriding USD primvar lookups
and material_map before assignment — same pattern as still renders.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The initial implementation only overrode the material_map dict in the task,
but the Blender USD primvar path bypassed it. Now:
- Added --material-override named CLI arg parsed in _blender_args.py
- Both Mode A (factory) and Mode B (template) in _blender_scene_setup.py
override usd_material_lookup and material_map when set
- Passed through full chain: task → step_processor → render_blender → CLI → Blender
- Tested: 175-part bearing rendered with single Steel-Bare material (1/1 materials)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add `material_override` nullable column on OutputType (DB migration)
- When set, ALL product parts get rendered with this single material
- Override applies after alias resolution in render_order_line task
- Admin UI: dropdown in OutputType table to select a library material
- Display: amber badge showing active override material name

Root cause 1: BRepBuilderAPI_Transform(shape, trsf, copy=True) destroys
all Poly_Triangulation data. The mm→m scaling was applied before export,
wiping the tessellation from BRepMesh_IncrementalMesh.
Fix: Remove BRepBuilderAPI_Transform entirely — RWGltf_CafWriter already
handles mm→m conversion and Z-up→Y-up rotation internally.
Root cause 2: RWGltf_CafWriter with MergeFaces=False (the default) fails
to find per-face tessellation from the XCAF component hierarchy, producing
degenerate meshes (~2 vertices per face instead of thousands).
Fix: SetMergeFaces(True) to compose face triangulations into proper
per-shape mesh buffers. Vertex count goes from 1,212 to 46,573.
Also bumps cache key version to v2 to invalidate broken cached GLBs.
