- 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

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)

- 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.

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

- export_step_to_usd.py: change stage from Y-up to Z-up, keep (X,-Z,Y)
transform — matches GLB orientation exactly (verified: bounding box match)
- export_glb.py: include canonical_material in resolved_material_assignments
DB field (was being dropped during manifest parsing)
- import_usd.py: use pxr customData read (not string primvars — Blender
ignores those, confirmed by testing)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- export_step_to_usd.py: accept --material_map CLI arg, write
schaeffler:canonicalMaterialName as customData on each Mesh prim,
fix geometry transform (strip shape Location before face exploration,
apply both face_loc and shape_loc sequentially)
- import_usd.py: after Blender USD import, use pxr to read customData
directly from the USD file — builds {part_key: material_name} lookup
(Blender ignores STRING primvars and customData, but pxr reads both)
- _blender_materials.py: add apply_material_library_direct() for exact
dict-based material assignment without name-matching heuristics
- _blender_scene_setup.py: prefer direct USD lookup, fall back to
name-matching for legacy USD files without material metadata
- export_glb.py (generate_usd_master_task): resolve material_map via
material_service.resolve_material_map() and pass to subprocess;
include material hash in cache key for invalidation
- ROADMAP.md: update P5 status, add M5-M7 milestones
Tested: 3/3 parts matched (ans_lfs120), 172/175 parts matched
(F-802007.TR4-D1-H122AG). Previous: 0/25 matched.

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,
and all .claude/commands/*.md skill files.

Previously the endpoint queued USD generation for ALL 295 completed CadFiles,
including 250 orphan CadFiles not linked to any product. Now filters to only
CadFiles referenced by at least one Product.cad_file_id, reducing the backfill
from ~285 to ~41 tasks.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- 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.

- Add per-file Redis SET NX EX 1800 locks to generate_gltf_geometry_task
and generate_usd_master_task — concurrent duplicates (e.g. double-click
of bulk action buttons) now log a warning and return immediately instead
of running two expensive OCC tessellation subprocesses on the same file
- Fix eng.dispose() called inside with Session() block in cache-hit path
of both tasks — moved to after the with block exits (Tasks 3+4 from plan)
- Add cad.updated_at = datetime.utcnow() in save_manual_material_overrides
(was missing vs parallel save_part_materials endpoint)

Fine production settings (0.03mm/0.05rad) with GMSH → CharacteristicLengthMax
0.45mm → OOM kill on large assemblies even with per-solid iteration.
GMSH quality is algorithmic (conforming seams, no fan triangles) — a denser
mesh provides no extra UV-unwrap benefit. Cap GMSH tessellation at preview
settings (0.1mm/0.1rad) in the production fallback path.
Normal path (GMSH + valid geometry GLB) is unaffected — continues to reuse
_geometry.glb directly without re-tessellating.
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

Introduces GMSH as an alternative to OCC BRepMesh for STEP→GLB tessellation.
GMSH produces conforming meshes that eliminate fan triangles at cylinder seam
edges — a structural limitation of OCC BRepMesh that cannot be fixed via
deflection parameters.
Changes:
- render-worker/Dockerfile: install gmsh>=4.15.0 + libglu1-mesa + libxft2
- export_step_to_gltf.py: --tessellation_engine occ|gmsh CLI arg +
_tessellate_with_gmsh() using BRep→GMSH→Poly_Triangulation write-back
- admin.py: tessellation_engine setting (SETTINGS_DEFAULTS, SettingsOut,
SettingsUpdate, validation)
- export_glb.py: pass tessellation_engine to export_step_to_gltf.py CLI in
both geometry and production GLB tasks
- Admin.tsx: radio button UI for OCC vs GMSH selection
Tested: 121 faces meshed, 0 BRepMesh fallback, 649K triangles on sample part.
Clean seam edges for UV unwrap — GMSH respects B-rep periodic face boundaries.

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.

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

- 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

OCC's RWGltf_CafWriter appends _AF0/_AF1 assembly-instance suffixes to
mesh object names when a part appears multiple times in an assembly.
The material matching in export_gltf.py only stripped Blender's .001
suffix, leaving 24/175 GLB objects without materials.
Fix: strip _AFN suffixes via while loop (handles nested _AF0_AF1),
add prefix fallback (longest key wins) as last resort before no-match.
Also improve build_materials_from_excel Jaccard matching:
- Strip _AFN and numeric hash suffixes (-21227) before tokenizing
- Add prefix-based fallback (step 3) before position fallback (step 4)
- Raise threshold 0.3 → 0.35 for better precision
- Guard prefix matches to len >= 5 to prevent trivial false positives
Result: Material substitution: 175/175 mesh objects assigned (was 151/175)

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).

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.
