chore(agents): rewrite all agent definitions for current architecture

Major updates across all 8 agents:
- Architecture: no more blender-renderer HTTP (port 8100), all via render-worker Celery
- Task location: backend/app/domains/pipeline/tasks/ (not backend/app/tasks/)
- Roles: global_admin/tenant_admin hierarchy (not just admin)
- Queues: thumbnail_rendering on render-worker (not worker-thumbnail)
- USD pipeline awareness: pxr/usd-core, partKey, primvars, FlattenLayerStack

New: Planner <-> Implementer failure loop:
- implement.md: Failure Protocol — [BLOCKED] tag + report to planner, stop
- plan.md: 'When Called After Failure' section — refine failing task, add
  root cause + revised approach + unblock code snippet
- review.md: on blocking issues, also update plan.md with [BLOCKED] tag

Agent-specific updates:
- plan.md: ROADMAP.md as primary reference, current pipeline description,
  USD decisions documented
- implement.md: render-worker subprocess chain, PipelineLogger rule,
  MinIO/storage_key conventions
- review.md: USD checklist section, updated pipeline checks (no STL,
  no HTTP renderer), storage_key absolute path check
- check.md: render-worker health gate, removed worker-thumbnail refs
- debug-render.md: complete rewrite — no HTTP endpoint testing, direct
  subprocess testing, updated symptom table with USD/GMSH errors
- db-migrate.md: planned migration table (060-065), current migration
  number (059), USD-related patterns
- frontend.md: role hierarchy, sceneManifest.ts reference, X-Tenant-ID
  interceptor note
- excel-import.md: minor cleanup, consistent format

## Wichtige Konventionen
## Critical CSS Convention
### API-Client
CSS variables with hex values **cannot** use Tailwind's opacity syntax:
```typescript
// Pattern für neue API-Datei
// ❌ BROKEN — produces transparent or invisible element
<div className="bg-surface/50 text-surface-alt">
// ✅ CORRECT — inline style for CSS variable colors
<div style={{ backgroundColor: 'var(--color-bg-surface)' }}>
<div style={{ color: 'var(--color-text-primary)' }}>
// Normal Tailwind classes without CSS vars work fine:
<div className="bg-white dark:bg-gray-800 rounded-lg p-4 shadow">
```
## Role Checks
```typescript
const { user } = useAuth()
const isGlobalAdmin = user?.role === 'global_admin'
const isTenantAdmin = user?.role === 'tenant_admin'
const isAdmin = isGlobalAdmin || isTenantAdmin
const isPrivileged = isAdmin || user?.role === 'project_manager'
// Render conditionally:
{isGlobalAdmin && <button>Manage all tenants</button>}
{isAdmin && <button>Change settings</button>}
{isPrivileged && <button>Trigger render</button>}
```
## API Client Pattern
```typescript
// frontend/src/api/my-resource.ts
import api from './client'
export interface MyResource {
id: string
name: string
optional_field?: string // Backend nullable → optional hier
optional_field?: string // Backend nullable → optional here
}
export async function getMyResource(id: string): Promise<MyResource> {
@@ -49,129 +92,112 @@ export async function getMyResource(id: string): Promise<MyResource> {

export async function updateMyResource(id: string, data: Partial<MyResource>): Promise<MyResource> {
const res = await api.put<MyResource>(`/my-resource/${id}`, data)
return res.data
}
```
### useQuery / useMutation Pattern
## useQuery / useMutation Pattern
```typescript
// Query (GET)
// GET
const { data, isLoading, error, refetch } = useQuery({
queryKey: ['my-resource', id],
queryFn: () => getMyResource(id),
enabled: !!id,
})
// Mutation (POST/PUT/DELETE)
const createMut = useMutation({
mutationFn: createMyResource,
onSuccess: (data) => {
queryClient.invalidateQueries({ queryKey: ['my-resource'] })
// ggf. Toast/Feedback
// POST/PUT/DELETE
const updateMut = useMutation({
mutationFn: (data: Partial<MyResource>) => updateMyResource(id, data),
onSuccess: () => {
queryClient.invalidateQueries({ queryKey: ['my-resource', id] })
},
onError: (err) => {
console.error(err)
// Fehler-Feedback
}
// Show user feedback
},
})
// Aufruf:
createMut.mutate({ name: 'test' })
// Ladezustand: createMut.isPending
// Loading state:
{updateMut.isPending && <RefreshCw className="w-4 h-4 animate-spin" />}
```
### CSS / Tailwind — WICHTIG
## Common UI Patterns
### Loading / Error states
```typescript
// ❌ FALSCH — CSS-Variablen mit Hex-Werten + Tailwind opacity = kaputt
<div className="bg-surface/50 bg-surface-alt">
// ✅ RICHTIG — inline style für CSS-Variablen
<div style={{ backgroundColor: 'var(--color-bg-surface)' }}>
<div style={{ backgroundColor: 'var(--color-bg-app)' }}>
// Normale Tailwind-Klassen ohne CSS-Variablen funktionieren normal:
<div className="bg-white dark:bg-gray-800 rounded-lg p-4">
if (isLoading) return <div className="flex justify-center p-8"><RefreshCw className="w-6 h-6 animate-spin" /></div>
if (error) return <div className="text-red-500 p-4">Error loading data</div>
if (!data?.length) return <div className="text-gray-400 p-8 text-center">No items yet</div>
```
### Rollen und Berechtigungen
### Status badge
```typescript
// Aus Auth-Context
const { user } = useAuth()
const isAdmin = user?.role === 'admin'
const isPrivileged = user?.role === 'admin' || user?.role === 'project_manager'
// Elemente nur für Admins/PMs
{isPrivileged && <button>Render dispatchen</button>}
{isAdmin && <button>Einstellung ändern</button>}
```
### Icons (ausschließlich lucide-react)
```typescript
import { RefreshCw, Download, Trash2, Plus, ChevronRight, AlertCircle } from 'lucide-react'
// Verwendung
<RefreshCw className="w-4 h-4" />
<RefreshCw className="w-4 h-4 animate-spin" /> // Loading-State
```
### Neue Seite anlegen
1. Datei in `frontend/src/pages/MyPage.tsx` erstellen
2. Route in `App.tsx` eintragen:
```typescript
<Route path="/my-page" element={<MyPage />} />
```
3. Navigation in Sidebar (`components/Sidebar.tsx`) hinzufügen (falls nötig)
## Häufige UI-Patterns im Projekt
### Ladezustand
```typescript
if (isLoading) return <div className="flex justify-center p-8"><RefreshCw className="animate-spin" /></div>
if (error) return <div className="text-red-500 p-4">Fehler beim Laden</div>
```
### Bestätigungs-Dialog vor destructiver Aktion
```typescript
const handleDelete = () => {
if (!confirm('Wirklich löschen?')) return
deleteMut.mutate(id)
}
```
### Badge / Status-Anzeige
```typescript
const statusColors = {
pending: 'bg-yellow-100 text-yellow-800',
const STATUS_COLORS: Record<string, string> = {
pending: 'bg-yellow-100 text-yellow-800',
processing: 'bg-blue-100 text-blue-800',
completed: 'bg-green-100 text-green-800',
failed: 'bg-red-100 text-red-800',
completed: 'bg-green-100 text-green-800',
failed: 'bg-red-100 text-red-800',
}
<span className={`px-2 py-0.5 rounded text-xs font-medium ${statusColors[status]}`}>
<span className={`px-2 py-0.5 rounded text-xs font-medium ${STATUS_COLORS[status] ?? 'bg-gray-100 text-gray-600'}`}>
{status}
</span>
```
### Thumbnail-Anzeige
### Authenticated thumbnail display
```typescript
// Thumbnail lädt über authenticated axios, nicht direkt in <img src>
// Never use <img src={url}> for authenticated endpoints
// Use blob URL via axios instead:
import { fetchThumbnailBlob } from '../api/cad'
const [thumbUrl, setThumbUrl] = useState<string>()
useEffect(() => {
if (!cadFileId) return
fetchThumbnailBlob(cadFileId).then(setThumbUrl)
return () => { if (thumbUrl) URL.revokeObjectURL(thumbUrl) }
let objectUrl: string
fetchThumbnailBlob(cadFileId).then(url => {
objectUrl = url
setThumbUrl(url)
})
return () => { if (objectUrl) URL.revokeObjectURL(objectUrl) }
}, [cadFileId])
<img src={thumbUrl} alt="Thumbnail" className="w-full h-full object-contain" />
```
## Abschluss
### Destructive action confirmation
```typescript
const handleDelete = () => {
if (!confirm('Delete this item? This cannot be undone.')) return
deleteMut.mutate(id)
}
```
Nach Implementation: "Frontend fertig. Änderungen: [Liste der Dateien]. Bitte mit `/review` prüfen."
### New page
1. Create `frontend/src/pages/MyPage.tsx`
2. Add route in `App.tsx`:
```typescript
<Route path="/my-page" element={<MyPage />} />
```
3. Add nav entry in `Layout.tsx` sidebar if needed
## Icons (lucide-react only)
```typescript
import { RefreshCw, Download, Trash2, Plus, ChevronRight, AlertCircle, Eye, EyeOff } from 'lucide-react'
<RefreshCw className="w-4 h-4" />
<RefreshCw className="w-4 h-4 animate-spin" /> // loading state
```
## Quality Gate Before Finishing
Always run before reporting done:
```bash
docker compose exec frontend npx tsc --noEmit 2>&1
```
Zero errors required. Type errors cause blank pages.
## Completion
After implementation: "Frontend complete. Changed: [list of files]. Please verify with `/review`."
