feat: sharp edge pipeline V02, tessellation presets, media cache-bust, GMSH plan
...
Sharp Edge Pipeline V02:
- export_step_to_gltf.py: replace BRep_Tool.Polygon3D_s (returns None in XCAF) with
GCPnts_UniformAbscissa curve sampling at 0.3mm step — extracts 17,129 segment pairs
- Inject sharp_edge_pairs + sharp_threshold_deg into GLB extras (scenes[0].extras)
via binary GLB JSON-chunk patching (no extra dependency)
- export_gltf.py: read schaeffler_sharp_edge_pairs from Blender scene custom props,
apply via KD-tree to mark edges sharp=True + seam=True (OCC mm Z-up → Blender transform)
- tools/restore_sharp_marks.py: dual-pass (dihedral angle + OCC pairs), updated coordinate
transform (X, -Z, Y) * 0.001
Tessellation:
- Admin UI: Draft / Standard / Fine preset buttons with active-state highlighting
- Default angular deflection: preview 0.5→0.1 rad, production 0.2→0.05 rad
- export_glb.py: read updated defaults from system_settings
Media / Cache:
- media/service.py: get_download_url appends ?v={file_size_bytes} cache-buster
- media/router.py: Cache-Control: no-cache for all download/thumbnail endpoints
Render pipeline:
- still_render.py / turntable_render.py: shared GPU activation + camera improvements
- render_order_line.py: global render position support
- render_thumbnail.py: updated defaults
Frontend:
- InlineCadViewer: file_size_bytes-aware URL update triggers re-fetch on regeneration
- ThreeDViewer: material panel, part selection, PBR mode improvements
- Admin.tsx: tessellation preset cards, GMSH setting dropdown
- MediaBrowser, ProductDetail, OrderDetail, Orders: various UI improvements
- New: MaterialPanel, GlobalRenderPositionsPanel, StepIndicator components
- New: renderPositions.ts API client
Plans / Docs:
- plan.md: GMSH Frontal-Delaunay tessellation plan (6 tasks)
- LEARNINGS.md: OCC Polygon3D_s None issue + GCPnts fix
- .gitignore: add backend/core (core dump from root process)

fix(export_glb): upsert MediaAsset instead of DELETE+INSERT to preserve stable URLs
...
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.

refactor(section-a+c): decompose step_tasks.py into pipeline domain
...
Section A — 1172-line step_tasks.py split into 4 focused modules under
backend/app/domains/pipeline/tasks/:
- extract_metadata.py: process_step_file, reextract_cad_metadata,
_auto_populate_materials_for_cad, bbox helpers + PipelineLogger
- render_thumbnail.py: render_step_thumbnail, regenerate_thumbnail
+ PipelineLogger instrumentation
- render_order_line.py: dispatch_order_line_render, render_order_line_task
(full still+turntable paths) + PipelineLogger step tracking
- export_glb.py: generate_gltf_geometry_task, generate_gltf_production_task
All task names preserved (app.tasks.step_tasks.*) for backward compat.
step_tasks.py is now a 23-line import-only shim.
Section C — celery_app.py task routing:
- app.domains.pipeline.tasks.* → step_processing (primary route)
- All 4 new modules added to include list for Celery discovery
- app.tasks.step_tasks.* kept as legacy fallback for in-flight tasks
