Blenders natives Asset-Library-System ist breiter und deckt beides ab. - -**Entscheidung:** Blender Asset Library als primäres System für Assets: - -```python -# render-worker/scripts/asset_library.py - -def apply_asset_library(blend_path: str, material_map: dict, modifier_map: dict): - """ - Lädt Assets aus einer Asset-Library .blend-Datei: - 1.

"Bevel Sharp Edges", "Add Chamfer", "Clean Geometry" als wiederverwendbare Node-Groups -- Asset-Katalog im Browser durchsuchbar ohne Blender zu starten - ---- - -## 4.

No consistent prefix, no structured fields. - -**Target:** -A `PipelineLogger` class that wraps Python's `logging` module and additionally writes -structured events to the DB (`audit_log` or a new `pipeline_events` table). - -**Design:** -```python -# backend/app/core/pipeline_logger.py -class PipelineLogger: - PREFIX_FORMAT = "[{step_name}]" - - def step_start(self, step: str, context: dict): ... - def step_progress(self, step: str, pct: int, msg: str): ... - def step_done(self, step: str, duration_s: float, result: dict): ... - def step_error(self, step: str, error: str, exc: Exception | None): ... -``` - -Every log call emits: -- Python `logging` line with `[STEP_NAME] message` -- Redis `log_task_event` for SSE streaming -- Optional DB insert into `pipeline_events(task_id, step_name, level, message, duration_s, context JSONB, created_at)` - -**Files to create:** -- `backend/app/core/pipeline_logger.py` — PipelineLogger class -- `backend/alembic/versions/048_pipeline_events.py` — new table migration - -**Files to modify:** -- All task files to replace bare `logger.info/error` with `PipelineLogger` calls -- `backend/app/core/task_logs.py` — keep Redis SSE publish, add DB write path - -### 1.2 Render Job Document - -**Current state:** -`OrderLine.render_log` is a loosely-structured JSONB dict. No schema, no state machine, -no step-level results stored. - -**Target:** -A `RenderJobDocument` JSONB schema stored in `order_lines.render_job_doc`.

Celery tasks bypass RLS -entirely (they use sync engines without `SET LOCAL app.current_tenant_id`). - -**Problem:** -Migration 036 enables RLS, but `build_tenant_db_dep()` in `database.py` actually yields -`db` without setting the tenant context (line 92: `yield db # context-setting happens -via set_tenant_context when needed`). This means most endpoints are silently bypassing RLS. - -**Target:** -A FastAPI middleware `TenantContextMiddleware` that automatically sets RLS context for -every request based on the JWT `tenant_id` claim. - -```python -# backend/app/core/middleware.py -class TenantContextMiddleware(BaseHTTPMiddleware): - async def dispatch(self, request: Request, call_next): - # Extract JWT, decode tenant_id - # Store in request.state.tenant_id - # After DB session is acquired, SET LOCAL app.current_tenant_id - ... -``` - -**JWT changes:** -`create_access_token()` must embed `tenant_id` in claims: -```python -payload = {"sub": user_id, "role": role, "tenant_id": str(tenant_id), "exp": expires} -``` - -**Celery tasks:** -All sync DB sessions in Celery tasks must receive `tenant_id` as a task argument and -execute `session.execute(text("SET LOCAL app.current_tenant_id = :tid"), {"tid": tenant_id})` -immediately after session creation. Add a `_set_tenant(session, tenant_id)` helper in -`backend/app/core/db_utils.py`. - -**Files to create:** -- `backend/app/core/middleware.py` — TenantContextMiddleware -- `backend/app/core/db_utils.py` — `_set_tenant(session, tenant_id)` - -**Files to modify:** -- `backend/app/main.py` — add middleware -- `backend/app/utils/auth.py` — embed tenant_id in JWT -- All Celery task functions — accept `tenant_id: str | None` parameter, call `_set_tenant` - -### 1.4 Process Step Registry - -**Current state:** -Pipeline steps are implicit — scattered across `step_tasks.py`, `rendering/tasks.py`, -`step_processor.py`, `render_blender.py`. No central definition. - -**Target:** -A `ProcessStep` enum and registry that all tasks reference by name. - -```python -# backend/app/domains/pipeline/steps.py -class ProcessStep(str, enum.Enum): - UPLOAD_STEP = "upload_step" - PARSE_EXCEL = "parse_excel" - EXTRACT_METADATA = "extract_metadata" - OCC_GLB_EXPORT = "occ_glb_export" - RENDER_THUMBNAIL = "render_thumbnail" - RENDER_STILL = "render_still" - RENDER_TURNTABLE = "render_turntable" - EXPORT_GLB = "export_glb" - EXPORT_BLEND = "export_blend" - DELIVER = "deliver" -``` - -Each step maps to exactly one Celery task and one workflow node type. This enum becomes -the contract between the visual workflow editor and the task executor. - ---- - -## Phase 2: Pipeline Modularity (Weeks 3–4) - -Break up `step_tasks.py` (1,170 lines). One file = one pipeline stage. - -### 2.1 Decompose step_tasks.py - -**Current functions and their new homes:** - -| Current location | Function | Target file | -|---|---|---| -| `step_tasks.py` | `process_step_file` | `domains/pipeline/tasks/extract_metadata.py` | -| `step_tasks.py` | `render_step_thumbnail` | `domains/pipeline/tasks/render_thumbnail.py` | -| `step_tasks.py` | `generate_gltf_geometry_task` | `domains/pipeline/tasks/export_glb_geometry.py` | -| `step_tasks.py` | `generate_gltf_production_task` | `domains/pipeline/tasks/export_glb_production.py` | -| `step_tasks.py` | `regenerate_thumbnail` | `domains/pipeline/tasks/render_thumbnail.py` | -| `step_tasks.py` | `dispatch_order_line_render` | `domains/pipeline/tasks/dispatch.py` | -| `step_tasks.py` | `render_order_line_task` | **DELETE** (duplicate of `domains/rendering/tasks.render_order_line_still_task`) | -| `step_tasks.py` | `reextract_cad_metadata` | `domains/pipeline/tasks/extract_metadata.py` | -| `step_tasks.py` | `_auto_populate_materials_for_cad` | `domains/pipeline/tasks/auto_materials.py` | -| `step_tasks.py` | `_bbox_from_glb`, `_bbox_from_step_cadquery` | `domains/pipeline/tasks/bbox.py` | -| `rendering/tasks.py` | `render_order_line_still_task` | `domains/rendering/tasks/render_still.py` | -| `rendering/tasks.py` | `render_turntable_task` | `domains/rendering/tasks/render_turntable.py` | -| `rendering/tasks.py` | `export_gltf_for_order_line_task` | `domains/pipeline/tasks/export_glb_geometry.py` | -| `rendering/tasks.py` | `export_blend_for_order_line_task` | `domains/rendering/tasks/export_blend.py` | -| `rendering/tasks.py` | `publish_asset` | `domains/media/tasks.py` | - -**`step_tasks.py` becomes a compatibility shim** (import-only, deprecated) until all -callers are updated. Remove it in Phase 3. - -### 2.2 Render Job Document Integration - -Every Celery task in the new structure: -1. Reads/creates `RenderJobDocument` at task start -2. Updates the relevant step via `job_doc.update_step(step_name, status="running")` -3. On completion: `job_doc.update_step(step_name, status="done", duration_s=elapsed)` -4. On failure: `job_doc.set_state("failed")` + `job_doc.append_error(...)` -5. Writes document back to `order_lines.render_job_doc` - -### 2.3 Render Job Cancellation (Proper) - -**Current problem:** -`celery_app.control.revoke("render-{line_id}", terminate=True)` — this ID is synthetic -and does not match the actual Celery task ID, so revoke is a no-op. The Blender process -continues running. - -**Solution:** -1. Store the actual Celery task ID in `render_job_doc.celery_task_id` when the task starts -2. Cancel endpoint reads `render_job_doc.celery_task_id` and revokes with that real ID -3. The render subprocess uses `start_new_session=True` (already done in `render_blender.py`) - and stores `proc.pid` in the job document -4. On SIGTERM, the Celery task's signal handler calls `os.killpg(pgid, SIGTERM)`, waits 10s, - then `os.killpg(pgid, SIGKILL)` -5. Clean up: remove partial output file, remove `_frames_*` temp directory -6. Update `render_job_doc.state = "cancelled"`, clear `OrderLine.render_status = "cancelled"` - -**Files to modify:** -- `backend/app/api/routers/orders.py` — read celery_task_id from job doc, not synthetic ID -- `backend/app/domains/rendering/tasks/render_still.py` — store task ID + PID in job doc, - register SIGTERM handler -- `backend/app/domains/rendering/tasks/render_turntable.py` — same - -### 2.4 GPU-Primary Rendering - -**Current state:** -`cycles_device` defaults to "auto".

Frontend API Client Consistency - -All `frontend/src/api/*.ts` files should: -- Use the axios client from `api/client.ts` (which injects `X-Tenant-ID` header) -- Export typed interfaces for all response shapes -- Use `useQuery` / `useMutation` from TanStack Query, not bare `axios.get` in components - -**Audit needed:** Check each `api/*.ts` file to confirm `X-Tenant-ID` header is sent -(it is wired in the axios interceptor per commit 5da90b5, but verify all files use -the configured client, not `axios.create()` directly). - ---- - -## Architectural Decisions (ADRs) - -### ADR-001: Shared containers vs. per-tenant containers -**Decision:** Shared containers with PostgreSQL RLS -**Rationale:** Cost and complexity savings. RLS provides adequate isolation for internal use. -**Consequences:** Must ensure RLS is applied consistently (Phase 1.3). Blender sessions are -shared; GPU contention is managed via Celery queue depth, not isolation. - -### ADR-002: Render Job Document as JSONB -**Decision:** Store render job state machine as JSONB in `order_lines.render_job_doc` -**Rationale:** Avoids additional `workflow_node_results` table queries for debugging; -JSONB is flexible for schema evolution; indexed for state-based queries. -**Alternatives considered:** Separate `render_job_steps` table — rejected (too many joins -for the common "show me render status" query). - -### ADR-003: No per-render notifications -**Decision:** Suppress individual render.completed notifications; emit batch at order completion -**Rationale:** An order with 200 lines generates 200 notifications under the current model. -Batch summaries at order completion are actionable; per-render events are noise. -**Consequences:** Activity feed still records all events for debugging. - -### ADR-004: GPU-first rendering -**Decision:** Default `cycles_device = "gpu"`, explicit log on CPU fallback -**Rationale:** The render-worker has GPU reservation in docker-compose.yml. CPU fallback -should be visible and logged, not silent. -**Consequences:** Renders on machines without GPU will always log a CPU fallback warning. - -### ADR-005: Fallback material over palette -**Decision:** Replace `MATERIAL_PALETTE` rainbow fallback with `SCHAEFFLER_059999_FailedMaterial` -**Rationale:** Failed material assignments should be immediately visible (magenta) rather -than disguised as intentional palette colors. -**Consequences:** Parts with missing material mapping will render magenta in both -thumbnail and production renders. This is a feature, not a bug. - -### ADR-006: Blender 5.0.1 minimum, no version guards -**Decision:** Remove all `bpy.app.version` checks and `MIN_BLENDER_VERSION` guards -**Rationale:** The project is Blender 5.0.1-only. Version shims add complexity without value. -**Consequences:** Running with an older Blender binary will cause cryptic errors. Document -the minimum version requirement clearly in the Dockerfile and README. - ---- - -## What Gets Deleted - -### Python files to delete entirely: -- `backend/app/models/user.py` — compat shim -- `backend/app/models/cad_file.py` — compat shim -- `backend/app/models/order.py` — compat shim (if exists) -- `backend/app/models/order_item.py` — compat shim -- `backend/app/models/order_line.py` — compat shim -- `backend/app/models/material.py` — compat shim -- `backend/app/models/material_alias.py` — compat shim -- `backend/app/models/render_template.py` — compat shim -- `backend/app/models/output_type.py` — compat shim -- `backend/app/models/system_setting.py` — compat shim -- `backend/app/models/template.py` — compat shim -- `backend/app/models/render_position.py` — compat shim -- `backend/app/services/render_dispatcher.py` — 10-line shim -- `backend/app/services/material_service.py` — 3-line shim -- `backend/app/tasks/step_tasks.py` — after Phase 2 migration complete -- `backend/app/domains/rendering/tasks.py` — split into per-step files in Phase 2 - -### Directories to delete entirely: -- `blender-renderer/` — HTTP microservice, removed from docker-compose in refactor/v2 -- `threejs-renderer/` — removed in migration 033 -- `flamenco/` — removed in migration 032 - -### Code blocks to delete (within files): -- `render-worker/scripts/blender_render.py` lines 798–851 — Pillow overlay -- `render-worker/scripts/blender_render.py` line 17 — docstring Pillow mention -- `backend/app/services/render_blender.py` line 17 — `MIN_BLENDER_VERSION = (5, 0, 1)` -- `backend/app/services/render_blender.py` lines 229–233 — EEVEE-to-Cycles fallback -- `backend/app/services/step_processor.py` lines 19–31 — `MATERIAL_PALETTE` + `_material_to_color()` -- `backend/app/api/routers/admin.py` — `VALID_STL_QUALITIES`, `stl_quality` in all schemas - -### System settings to delete (DB migration): -- `stl_quality` — GLB-only pipeline, no STL concept -- `threejs_render_size` — renderer removed -- `thumbnail_renderer` — was multi-value (pillow|blender|threejs), now always blender - ---- - -## Migration Strategy - -### Deployment Order (Zero-Downtime) - -**Step 1 — DB migrations (non-breaking):** -- Run migrations 048–054 (new columns: `render_job_doc`, `rejection_reason`, feature flags, etc.) -- New columns are nullable, no existing queries break - -**Step 2 — Backend deploy (backward compatible):** -- Deploy new backend with compat shims in place -- New endpoints and middleware active -- Old endpoints still work -- JWT tokens are extended with `tenant_id` claim (existing tokens without it still work - via fallback in middleware) - -**Step 3 — Celery worker deploy:** -- Deploy new `domains/pipeline/tasks/` structure -- `step_tasks.py` compat shim routes to new functions -- Old task names still registered via shim - -**Step 4 — Frontend deploy:** -- New WorkflowEditor with validated step types -- HelpTooltip components added -- MediaBrowser refactor with virtual scroll - -**Step 5 — Cleanup (breaking):** -- Remove compat shims -- Delete `step_tasks.py` -- Rotate `JWT_SECRET_KEY` to force re-login (tenant_id now required in claims) -- Run DB migration to clean up stl_quality and threejs settings - -### Rollback Plan -- All migrations have `downgrade()` implemented -- Compat shims mean old task names still work during migration window -- `render_log` column kept alongside `render_job_doc` until all consumers migrated - -### Testing Before Delete -Before deleting any compat shim or old code, verify: -```bash -grep -rn "" backend/ frontend/ --include="*.py" --include="*.ts" --include="*.tsx" -``` -Must return 0 results from non-shim files. - ---- - -## Open Questions - -These require product decisions before implementation: - -1. **Tenant onboarding flow** — How are new tenants created?

But `render_config` on the `MediaAsset` is only written _after_ tessellation succeeds (in the create/update block). This is correct — `render_config` is written on the asset once it is created. However, the early `cad_file.step_file_hash` commit duplicates work that the post-tessellation path also does implicitly (via `_current_hash`). Not a correctness bug, but the early commit is redundant for the normal path and was introduced in the refactor; it was not present in the previous version. -**Recommendation**: Remove the two early `cad_file.step_file_hash = _current_hash; session.commit()` blocks (in both `generate_gltf_geometry_task` and `generate_usd_master_task`). The hash is already stored after tessellation completes.

No new dependencies. -- The Save button is correctly placed **outside** the `{showAdvancedTess && ...}` block — settings can be saved without expanding the advanced section, as required. -- Help text added to six inputs across the viewer settings section: both `title` attribute (browser tooltip) and a `

` description. All descriptions are accurate. -- Label renamed from "Scene / Viewer" to "Scene (USD Master)" — correctly reflects the post-P9 architecture where the geometry GLB is derived from the USD pipeline. - -### P9-1/P9-2 — Composite cache key in export_glb.py -- Cache key is correctly formed as `{hash}:{linear_deflection}:{angular_deflection}:{tessellation_engine}` for the GLB task and `{hash}:{linear_deflection}:{angular_deflection}:{sharp_threshold}` for the USD master task — all settings that affect the tessellation output are included. -- Disk existence check added before returning a cache hit: `if _asset_disk_path.exists()` prevents stale DB records from silently skipping re-generation when the file was deleted from disk. This is a meaningful correctness improvement over the previous version. -- `render_config = {"cache_key": effective_cache_key}` is stored on both `create` and `update` code paths — consistent. -- `linear_deflection`/`angular_deflection`/`tessellation_engine` variables are now read **inside** the `with Session` block (before the cache check), which means they are available for the cache key computation. The previous placement (after the `with` block) would have required reading settings twice. Clean refactor. -- `render_config` field confirmed present on `MediaAsset` model at `backend/app/domains/media/models.py:51` (`Mapped[dict | None] = mapped_column(JSONB, nullable=True)`). - -### P9-3 — `step_hash` exposed in CAD API response -- `"step_hash": cad.step_file_hash` added to the `get_objects` endpoint at `cad.py:232`. Field is nullable; no schema change required. Clean, minimal addition. -- `logger = logging.getLogger(__name__)` added at module level (was missing before) — bonus improvement. - -### P10-1 — Notification batching in NotificationCenter.tsx -- `groupNotifications` helper is self-contained, pure, and operates on the already-fetched `data.items` array. No backend round-trips. -- Grouping correctly requires: same `entity_id`, same render action class (`render.completed` or `render.failed`), and timestamps within 5 minutes. The `Math.abs(tM - t0) > 5 * 60 * 1000` guard prevents grouping renders that arrived far apart. -- `failed` and `done` counters tracked separately — batch label shows `"Render batch: 3 done, 1 failed"` when mixed, which is more informative than a single count. -- Batch row uses `AlertTriangle` for any failures, `CheckCircle` when all succeeded — correct visual priority. -- `createPortal` used for single-line reject modal — addresses the checklist requirement for modal inside a ``. - -### P10-2 — Per-line reject button and modal in OrderDetail.tsx -- `createPortal(…, document.body)` correctly escapes the `` context. Modal has both backdrop-click and X-button close. -- `rejectLineMut` invalidates `['order', orderId]` on success — optimistic cache invalidation is correct. -- `canRejectLine` guard (`isPrivileged && line.item_status !== 'rejected'`) prevents double-reject. Already-rejected lines do not show the button. -- `rejectOrderLine` in `orders.ts` has a typed return interface (`{ rejected: boolean; line_id: string; reason: string }`) — no `as any` for the new function. -- Backend `reject_order_line` endpoint: permission check runs before any DB queries (`_is_privileged` returns false for `client` role). `order_id` used in the `OrderLine.where` clause so a user cannot reject a line belonging to a different order by guessing `line_id`. No SQL injection vectors. -- `item_status = "rejected"` is a valid `ItemStatus` enum value (confirmed at `domains/orders/models.py:53`). -- `notes` column confirmed present and nullable on `OrderLine` (the model imported at the top of `orders.py` from `app.models.order_line`). - -### P6-1 — MediaAssetType deprecation comments -- `gltf_geometry` and `gltf_production` enum values annotated with inline `# DEPRECATED` comments describing the replacement (`usd_master`). Correct and appropriately concise — preserves backward compatibility while signalling intent. - -### Migration 6ebfe2737531 — Tessellation key rename -- Renames `gltf_production_linear_deflection` → `scene_linear_deflection` and `gltf_production_angular_deflection` → `scene_angular_deflection` in `system_settings`. -- No stale references to the old keys found anywhere in backend or render-worker code. -- `downgrade()` correctly reverses both renames. - -### admin.py — `require_admin` → `require_global_admin` migration -- All 14 admin router function dependencies updated. `require_global_admin` is defined in `auth.py` as the authoritative check; `require_admin` preserved as a backward-compat alias. - -### render_blender.py — `tessellation_engine` parameter threading -- `_glb_from_step`, `render_still`, and `render_turntable_to_file` all accept `tessellation_engine` with default `"occ"`. Passed through to the subprocess CLI flag `--tessellation_engine`. Consistent with `step_processor._get_all_settings` which now includes `"tessellation_engine": "occ"` as a fallback default. - -### export_step_to_usd.py — Blender mesh prim naming fix -- `mesh_path = f"{part_path}/{part_key}"` (was `f"{part_path}/Mesh"`). Blender 5.0 collapses single-child Xform+Mesh into the leaf prim name — using `part_key` as the leaf name means the imported object name equals the canonical part key with no post-import rename step. -- Learning documented in `LEARNINGS.md` with the precise Blender 5.0 USD import behaviour. - -### General -- No SQL injection vectors. All DB writes use ORM or parameterized bulk-update. -- No `print()` introduced in backend Python files. Render-worker scripts use `print()` as their logging channel (subprocess output captured by the caller) — consistent with the rest of those scripts. -- No hardcoded file paths or credentials in any changed file. -- All FastAPI route handlers `async def`; all Celery tasks `def`. Async consistency maintained. -- LEARNINGS.md and ROADMAP.md updated in the same change set. - ---- +1. **CLAUDE.md accuracy**: The rewrite is comprehensive — services, queues, roles, endpoints, project structure, and pipeline all match the actual codebase. Future AI sessions will get correct context. +2. **Type safety wins**: 9 unnecessary `as any` casts eliminated. The `OrderItem` type extension is correct — `material` (not `material_name`) matches the `CadPartMaterials` component. +3. **Clean removal**: 2,629 lines of obsolete content deleted (PLAN.md + PLAN_REFACTOR.md). No orphaned references remain. +4. **Zero behavioral changes**: All modifications are documentation, types, and dead code removal. No risk of regression. ## Recommendation -Approve with the redundant local `sql_update` import cleaned up (Low) and the pre-existing `bg-surface-hover/30` opacity issue tracked for a follow-up pass (Medium, not introduced by this PR). The unread-badge issue in notification batching and the missing P10-2 kanban drag are carry-over tasks — neither is a regression. No blockers to merging. +Approved. All 4 tracks complete, all acceptance gates pass. Changes are pure hygiene — no behavioral impact, no new features. ---- - -Review complete. Result: ⚠️ +Review complete. Result: ✅
