# tOS Backend Architecture Memory
## Project Structure
- **Location**: `/home/mehmed/Entwicklung/githubProjekte/tOS/apps/api/`
- **Framework**: NestJS 10.3.x with TypeScript strict mode
- **ORM**: Prisma 5.8.x with PostgreSQL
- **Auth**: JWT-based with Keycloak integration support
## Key Conventions
- **Language**: English for all code/comments
- **Files**: kebab-case, **Variables**: camelCase
- **API Prefix**: `/api/v1/`
- **Global Guards**: JwtAuthGuard -> RolesGuard -> PermissionsGuard
- **IDs**: CUID, **Soft Delete**: `isActive` boolean
## Security - Encryption (CRITICAL)
- `EncryptionService` in `src/common/services/` (AES-256-GCM)
- **Encrypted fields in Employee model:**
- `salary` - Stored as encrypted String (not Decimal!)
- `bankAccount` - Stored as encrypted JSON string
- Access via `findOne(id, includeSensitive=true)` for decryption
- Config: `ENCRYPTION_KEY` env variable (required in production)
## Auth Pattern
- Routes protected by default via global JwtAuthGuard
- `@Public()` for open endpoints
- `@Roles('admin', 'hr-manager')` for role-based access
- `@RequirePermissions(Permission.USERS_CREATE)` for fine-grained
- `@CurrentUser()` to get JWT payload
## Available Roles
admin, hr-manager, team-lead, employee
## Module Exports
All modules export via `index.ts` barrel files:
- `/modules/index.ts` exports: audit, dashboard, departments, user-preferences, integrations, lean, hr
- `/modules/lean/index.ts` exports: s3-planning, skill-matrix, morning-meeting
- `/modules/hr/index.ts` exports: employees, absences, time-tracking
## Health Endpoints
- Located at `src/health/` (NOT `src/modules/health/`)
- `GET /health` - Full check (database, memory, modules status)
- `GET /health/liveness` - Kubernetes liveness
- `GET /health/readiness` - Database connectivity
- `ModulesHealthIndicator` reports core/hr/lean/integrations status
## Test Infrastructure
- **Web (apps/web)**: Vitest 2.x + @testing-library/react + jsdom
- Config: `apps/web/vitest.config.ts`
- Setup: `apps/web/src/test/setup.ts` (imports @testing-library/jest-dom/vitest)
- Scripts: `test` (vitest run), `test:watch` (vitest)
- **API (apps/api)**: Jest 29.x + ts-jest + @nestjs/testing
- Config: inline in `package.json` under `jest` key
- rootDir: `src`, testRegex: `.*\\.spec\\.ts$`
- Module alias: `@/` -> `<rootDir>/`
## Phase 3: Integrations
Location: `src/modules/integrations/`
Sub-modules: credentials/, sync/, status/, jobs/
Types: PLENTYONE, ZULIP, TODOIST, FREESCOUT, NEXTCLOUD, ECODMS, GEMBADOCS
## Phase 4: LEAN
Location: `src/modules/lean/`
- `s3-planning/` - 3S/5S audit planning (permissions: S3_VIEW/CREATE/UPDATE/DELETE/MANAGE)
- `skill-matrix/` - Skills and employee skill entries
- `morning-meeting/` - SQCDM meetings, topics, actions (permissions: MEETING_VIEW/CREATE/UPDATE/DELETE)
## Phase 5: HR
Location: `src/modules/hr/`
- `employees/` - CRUD, org chart, **encrypted salary + bankAccount**
- `absences/` - Approval workflow (PENDING->APPROVED/REJECTED/CANCELLED)
- `time-tracking/` - Clock in/out, German ArbZG break compliance
### Absences Workflow
- Auto-approved: SICK, SICK_CHILD
- Vacation balance: 30 days/year, pro-rata by entry date
### Time Tracking
- German labor law breaks: >6h=30min, >9h=45min
- Monthly summary with overtime calculation
## Scripts (from root)
```bash
pnpm run dev:api # Development server
pnpm run db:migrate # Run migrations
pnpm run db:generate # Generate Prisma client
pnpm run db:seed # Seed default data
```
## Common Patterns
- Use `CommonModule` (@Global) for shared services like EncryptionService
- DTOs with class-validator for input validation
- Swagger decorators for API documentation
- `@AuditLog('Entity', 'ACTION')` for audit trail

# tOS Test Infrastructure
## Frontend (apps/web) - Vitest
### Configuration
- `vitest.config.ts` at project root of apps/web
- Uses `@vitejs/plugin-react` for JSX transform
- jsdom environment for DOM testing
- `globals: true` so `describe/it/expect` are global
- Path alias `@` -> `./src` matching tsconfig
- CSS disabled in tests (`css: false`)
- Setup file: `src/test/setup.ts` imports `@testing-library/jest-dom/vitest`
### Dependencies (devDependencies)
- vitest ^2.1.8
- @testing-library/react ^16.1.0
- @testing-library/jest-dom ^6.6.3
- @testing-library/user-event ^14.5.2
- @vitejs/plugin-react ^4.3.4
- jsdom ^25.0.1
### Test Files
- `src/lib/utils.test.ts` - Tests for cn(), getInitials(), capitalize(), truncate(), safeJsonParse(), generateId(), isServer(), isClient()
- `src/components/ui/badge.test.tsx` - Badge component rendering with all variants
- `src/hooks/use-toast.test.ts` - Tests reducer logic and toast() function
### Run Commands
```bash
pnpm --filter web test # vitest run
pnpm --filter web test:watch # vitest (watch mode)
```
## Backend (apps/api) - Jest
### Configuration
- Inline in `package.json` under `"jest"` key
- ts-jest transform for TypeScript
- Node test environment
- Module alias: `@/` -> `<rootDir>/` (rootDir = src)
- Test regex: `.*\.spec\.ts$`
### Dependencies (already present)
- jest ^29.7.0
- ts-jest ^29.1.1
- @nestjs/testing ^10.3.0
- @types/jest ^29.5.11
- supertest ^6.3.3
### Test Files
- `src/health/health.controller.spec.ts` - Health controller (check, liveness, readiness)
- `src/common/services/encryption.service.spec.ts` - EncryptionService (encrypt/decrypt, objects, empty strings, generateKey, init)
### Test Patterns for NestJS
- Use `Test.createTestingModule()` for DI setup
- Mock all dependencies with `{ provide: X, useValue: mockX }`
- Call `module.get<T>(T)` to get the instance under test
- For services with `onModuleInit()`, call it manually in `beforeEach`
- Use `jest.clearAllMocks()` in `afterEach`
### Run Commands
```bash
pnpm --filter api test # jest
pnpm --filter api test:watch # jest --watch
pnpm --filter api test:cov # jest --coverage
```

# tOS Infrastructure Memory
## Docker Stack
- **Location**: `/home/mehmed/Entwicklung/githubProjekte/tOS/docker/`
- **Compose file**: `docker-compose.yml` (name: tos)
- **Services**: PostgreSQL 16, Redis 7, Keycloak 24.0
- **Network**: `tos-network` (bridge)
- **Volumes**: `tos-postgres-data`, `tos-redis-data`
## Ports (Default)
| Service | Port |
|------------|------|
| PostgreSQL | 5432 |
| Redis | 6379 |
| Keycloak | 8080 |
| API | 3001 |
| Frontend | 3000 |
## Keycloak Configuration
- **Realm**: `tOS`
- **Clients**: `tos-frontend` (public), `tos-backend` (confidential)
- **Roles Hierarchy**:
- admin -> hr-manager, manager, department_head, team-lead, employee
- hr-manager -> employee
- manager -> department_head, employee
- department_head -> team-lead, employee
- team-lead -> employee
- **Test Users**: admin, manager, depthead, employee, hrmanager, teamlead
- **Default passwords**: `<username>123` (temporary)
## Environment Variables
- **Root `.env.example`**: Application config (NextAuth, Keycloak, API keys)
- **Docker `.env.example`**: Container config (ports, credentials)
- **Critical Production Secrets**:
- `ENCRYPTION_KEY` - 32 bytes for credential encryption
- `JWT_SECRET` - API token signing
- `NEXTAUTH_SECRET` - Session encryption
- `KEYCLOAK_BACKEND_CLIENT_SECRET`
## Package Scripts
```bash
pnpm docker:up # Start infrastructure
pnpm docker:down # Stop infrastructure
pnpm docker:logs # View logs
pnpm docker:reset # Destroy volumes and restart
pnpm dev # Start dev servers
```
## Known Issues / Lessons Learned
- Keycloak 24+ (UBI9) has no curl; use bash TCP redirect for health checks
- Realm import: file must be at `/opt/keycloak/data/import/` with `--import-realm` flag
- Health check `start_period` should be 90s+ for Keycloak (Java startup)

# tOS Frontend - Agent Memory
## Project Overview
- **Type**: Enterprise Web Dashboard (Next.js 14+ App Router)
- **Location**: `/home/mehmed/Entwicklung/githubProjekte/tOS/apps/web/`
- **Language**: Code/comments in English, UI in German (default) via i18n
## Tech Stack
- Next.js 14+ with App Router
- TypeScript (strict mode)
- Tailwind CSS + shadcn/ui (new-york style)
- next-themes for dark/light mode
- next-intl for i18n (de default, en supported)
- NextAuth with Keycloak provider
- Framer Motion for animations
- Zustand for client state (sidebar-store, dashboard-store)
- TanStack Query for server state
- TanStack Table for data tables
- Recharts for chart components
- dnd-kit for drag and drop
- date-fns for date formatting
- Lucide React for icons
## File Structure
```

```
## Key Patterns
### 1. Server/Client Component Split
- `page.tsx` = Server Component (metadata only)
- `*-content.tsx` = Client Component (receives locale prop)
### 2. Widget System (Phase 2)
- Registry pattern: `widget-registry.ts` defines all widget types
- Drag & drop: dnd-kit with SortableContext
- Persistence: Zustand store with localStorage
- Each widget: WidgetContainer wrapper + specific content
### 3. Role-Based Navigation
- NavItem has optional `requiredRoles: UserRole[]`
- Sidebar filters items via `filterNavItems(items, userRoles)`
- Roles: admin, manager, department_head, employee
### 4. DataTable Pattern
- Generic component: `DataTable<TData, TValue>`
- Use `DataTableColumnHeader` for sortable columns
- Features: search, pagination, column visibility, row selection
### 5. Chart Components
- Wrap Recharts in `ChartContainer` for consistent styling
- Support loading states, empty states
- Theme-aware colors via CSS variables
### 6. Integration Hooks (Phase 3)
- TanStack Query with 30s staleTime
- Mock data for development, TODO comments for API replacement
- Query key factories: `ordersKeys`, `messagesKeys`, etc.
- Optimistic updates for complete/toggle actions
### 7. Integration Widgets
- Widget categories: `integrations` added to registry
- requiredRoles: ['manager', 'admin'] for sensitive widgets
- Each widget uses WidgetContainer + specific hook
## Sidebar Behavior
- Expanded: 240px, Collapsed: 64px
- Collapsible sub-navigation with ChevronDown animation
- Tooltip shows sub-nav when collapsed
## i18n Keys
- Flat structure with nested objects: `widgets.clock.name`
- Use ASCII for German (oe, ae, ue) to avoid encoding issues
## Dependencies Added (Phase 2)
- @dnd-kit/core, @dnd-kit/sortable, @dnd-kit/utilities
- @tanstack/react-table
- @radix-ui/react-checkbox, collapsible, popover, select, tabs
- recharts, date-fns
## Dependencies Added (Phase 3)
- @radix-ui/react-switch (for Switch component)
## Integration Types (Phase 3+)
- `plenty-one`: PlentyONE (e-commerce) - OrdersWidget
- `zulip`: ZULIP (chat) - ChatWidget
- `todoist`: Todoist (tasks) - TasksWidget
- `freescout`: FreeScout (helpdesk) - TicketsWidget
- `nextcloud`: Nextcloud (files) - FilesWidget
- `ecodms`: ecoDMS (documents) - DocumentsWidget
- `gembadocs`: GembaDocs (audits/compliance) - GembaDocsWidget

# Component Patterns - tOS Frontend
## Layout Component Pattern
```tsx
// src/components/layout/sidebar.tsx
'use client';
import { usePathname } from 'next/navigation';
import { motion } from 'framer-motion';
import { useSidebarStore } from '@/stores/sidebar-store';
export function Sidebar({ locale }: { locale: string }) {
const { isExpanded, toggleSidebar } = useSidebarStore();
const pathname = usePathname();
return (
<motion.aside
initial={false}
animate={{ width: isExpanded ? 240 : 64 }}
transition={{ duration: 0.2, ease: 'easeInOut' }}
className="fixed left-0 top-0 z-40 h-screen border-r bg-sidebar"
>
{/* Content */}
</motion.aside>
);
}
```
## Page with Metadata Pattern
```tsx
// page.tsx (Server Component)
import { Metadata } from 'next';
import { getTranslations } from 'next-intl/server';
import { ContentComponent } from './content-component';
export async function generateMetadata(): Promise<Metadata> {
const t = await getTranslations('namespace');
return { title: t('title') };
}
export default function Page() {
return <ContentComponent />;
}
// content-component.tsx (Client Component)
'use client';
import { useTranslations } from 'next-intl';
export function ContentComponent() {
const t = useTranslations('namespace');
return <div>{t('key')}</div>;
}
```
## Zustand Store Pattern
```tsx
// src/stores/sidebar-store.ts
import { create } from 'zustand';
import { persist } from 'zustand/middleware';
interface SidebarState {
isExpanded: boolean;
toggleSidebar: () => void;
}
export const useSidebarStore = create<SidebarState>()(
persist(
(set) => ({
isExpanded: true,
toggleSidebar: () => set((state) => ({ isExpanded: !state.isExpanded })),
}),
{
name: 'tos-sidebar-state',
partialize: (state) => ({ isExpanded: state.isExpanded }),
}
)
);
```
## Animation Pattern with Framer Motion
```tsx
import { motion } from 'framer-motion';
// Staggered list animation
<motion.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
transition={{ staggerChildren: 0.1 }}
>
{items.map((item, index) => (
<motion.div
key={item.id}
initial={{ opacity: 0, y: 20 }}
animate={{ opacity: 1, y: 0 }}
transition={{ delay: index * 0.1, duration: 0.3, ease: 'easeOut' }}
>
{item.content}
</motion.div>
))}
</motion.div>
```
## shadcn/ui Component with Variants
```tsx
// src/components/ui/button.tsx
import { cva, type VariantProps } from 'class-variance-authority';
const buttonVariants = cva(
'inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors',
{
variants: {
variant: {
default: 'bg-primary text-primary-foreground hover:bg-primary/90',
destructive: 'bg-destructive text-destructive-foreground',
outline: 'border border-input bg-background hover:bg-accent',
ghost: 'hover:bg-accent hover:text-accent-foreground',
},
size: {
default: 'h-9 px-4 py-2',
sm: 'h-8 px-3 text-xs',
lg: 'h-10 px-8',
icon: 'h-9 w-9',
},
},
defaultVariants: {
variant: 'default',
size: 'default',
},
}
);
export interface ButtonProps
extends React.ButtonHTMLAttributes<HTMLButtonElement>,
VariantProps<typeof buttonVariants> {
asChild?: boolean;
}
```
## Provider Composition Pattern
```tsx
// src/components/providers/index.tsx
'use client';
export function Providers({ children }: { children: ReactNode }) {
return (
<SessionProvider>
<QueryProvider>
<ThemeProvider>
{children}
</ThemeProvider>
</QueryProvider>
</SessionProvider>
);
}
```
## i18n Usage Pattern
```tsx
// In components
import { useTranslations } from 'next-intl';
export function Component() {
const t = useTranslations('namespace');
return <span>{t('key', { param: 'value' })}</span>;
}
// In server components
import { getTranslations } from 'next-intl/server';
export async function ServerComponent() {
const t = await getTranslations('namespace');
return <span>{t('key')}</span>;
}
```
## Protected Route Layout Pattern
```tsx
// src/app/[locale]/(auth)/layout.tsx
'use client';
export default function AuthLayout({ children, params: { locale } }) {
const { isExpanded } = useSidebarStore();
return (
<div className="min-h-screen bg-background">
<div className="hidden lg:block">
<Sidebar locale={locale} />
</div>
<MobileSidebar locale={locale} />
<div className={cn(
'flex min-h-screen flex-col transition-[margin-left] duration-200',
'ml-0',
isExpanded ? 'lg:ml-[240px]' : 'lg:ml-[64px]'
)}>
<Header locale={locale} />
<main className="flex-1 p-4 md:p-6 lg:p-8">
<PageTransition>{children}</PageTransition>
</main>
</div>
</div>
);
}

- `DEFAULT_BREAK_MINUTES`, `REQUIRED_BREAK_MINUTES`, `EXTENDED_BREAK_MINUTES`
- `SKILL_LEVELS`, `S3_CATEGORIES`, `SQCDM_CATEGORIES`
- `HTTP_STATUS`, `DATE_FORMATS`
- `API_VERSION`, `API_PREFIX`, `DEFAULT_PAGE_SIZE`, `MAX_PAGE_SIZE`
- `PERMISSIONS`, `ROLE_PERMISSIONS`
### Types (`@tos/shared` or `@tos/shared/types`)
- `User`, `UserRole`, `UserPreferences`, `DashboardWidgetConfig`, `NotificationPreferences`
- `CreateUserDto`, `UpdateUserDto`
- `Department`, `DepartmentCode`, `DepartmentWithStats`, `CreateDepartmentDto`, `UpdateDepartmentDto`
- `Employee`, `ContractType`, `TimeEntry`, `TimeEntryType`, `Absence`, `AbsenceType`, `ApprovalStatus`
- `AuthUser`, `TokenPayload`, `LoginRequest`, `AuthResponse`, `Permission`
- Skill Matrix: `Skill`, `SkillMatrixEntry`, `SkillMatrix`, `SkillGapAnalysis`, etc.
## Integration Patterns
### Web App (apps/web)
- `transpilePackages: ['@tos/shared']` in next.config.mjs (transpiles source directly)
- `"@tos/shared": "workspace:*"` in package.json
- Import directly: `import { getInitials } from '@tos/shared'`
### API App (apps/api)
- `"@tos/shared": "workspace:*"` in package.json
- Uses built dist (CJS) - requires `pnpm --filter @tos/shared build` first
- Import: `import { calculateWorkingDays, DEFAULT_VACATION_DAYS } from '@tos/shared'`
## Key Differences: Local vs Shared
### getInitials
- **Shared**: `getInitials(firstName: string, lastName: string)` - two args
- **Web local** (`@/lib/utils`): `getInitials(name: string)` - single full name string, splits on space
- Both coexist; use shared in components with firstName/lastName, local in header with full name
### Date Formatting
- **Shared**: `formatDate()` uses `{ day: '2-digit', month: '2-digit', year: 'numeric' }`, hardcoded `de-DE`
- **Web local**: `formatDate()` uses `{ year: 'numeric', month: 'long', day: 'numeric' }`, accepts locale param
- **Web local**: `formatDateShort()` is equivalent to shared `formatDate()` but accepts locale param
- NOT interchangeable - different output format
### sleep
- Identical in both - web local now re-exports from `@tos/shared`
### ApprovalStatus / ContractType
- **Shared**: UPPERCASE (`'PENDING'`, `'FULL_TIME'`)
- **Web types**: lowercase (`'pending'`, `'full_time'`)
- NOT interchangeable - different casing convention

# Integration Specialist Memory - tOS Project
## Project Structure
- **API Location**: `/apps/api/src/`
- **Integrations Module**: `/apps/api/src/modules/integrations/`
- **Connectors**: `/apps/api/src/modules/integrations/connectors/`
## Phase 3 Connector Implementation (Completed)
### Base Infrastructure
- `base-connector.ts`: Abstract base class with axios, retry logic, rate limiting
- `errors/integration.errors.ts`: Custom error classes (Auth, Connection, RateLimit, API, Config, Validation)
### Implemented Connectors
#### PlentyONE (`/connectors/plentyone/`)
- **Auth**: OAuth2 Client Credentials flow
- **Token Management**: Auto-refresh with 5-minute buffer
- **Endpoints**: Orders, Stock, Statistics/Revenue
- **Rate Limiting**: 60s timeout (PlentyONE can be slow)
- **API Base**: `{baseUrl}/rest`
#### ZULIP (`/connectors/zulip/`)
- **Auth**: Basic Auth (email + API key)
- **Endpoints**: Messages, Streams, Users
- **API Base**: `{baseUrl}/api/v1`
- **Note**: Form-encoded POST requests for some endpoints
#### Todoist (`/connectors/todoist/`)
- **Auth**: Bearer Token
- **Endpoints**: Tasks, Projects, Sections, Labels
- **API Base**: `https://api.todoist.com/rest/v2`
- **Note**: Uses X-Request-Id header for idempotency
#### FreeScout (`/connectors/freescout/`)
- **Auth**: API Key via `X-FreeScout-API-Key` header
- **Endpoints**: Conversations, Mailboxes, Customers, Tags
- **API Base**: `{baseUrl}/api`
- **API Docs**: https://github.com/freescout-helpdesk/freescout/wiki/API
#### Nextcloud (`/connectors/nextcloud/`)
- **Auth**: Basic Auth (username + app-password)
- **Endpoints**: WebDAV Files, OCS Share API, CalDAV Calendar (basic)
- **API Bases**: `{baseUrl}/remote.php/dav/files/{user}` (WebDAV), `{baseUrl}/ocs/v2.php` (OCS)
- **Note**: WebDAV uses PROPFIND/MKCOL/MOVE/COPY; OCS needs `OCS-APIRequest: true` header
#### ecoDMS (`/connectors/ecodms/`)
- **Auth**: Session-based (login returns session ID, use `X-Session-Id` header)
- **Endpoints**: Documents, Folders, Classifications, Search
- **API Base**: `{baseUrl}/api/v1`
- **Note**: Session auto-refresh before expiry; supports file upload with FormData
## Environment Variables

## Key Patterns
### Retry Logic
- Exponential backoff with jitter (0.5-1.5x multiplier)
- Default: 3 retries, 1s initial delay, 30s max delay
- Retry on: 429, 500, 502, 503, 504
### Error Handling
- `IntegrationConnectionError`: Network issues (retryable)
- `IntegrationAuthError`: 401 responses (not retryable)
- `IntegrationRateLimitError`: 429 responses (retryable after delay)
- `IntegrationApiError`: Other API errors (retryable if 5xx)
### Module Structure
Each connector follows pattern:
1. `{name}.types.ts` - TypeScript interfaces
2. `{name}.connector.ts` - Low-level API client
3. `{name}.service.ts` - Business logic layer
4. `{name}.controller.ts` - HTTP endpoints
5. `{name}.module.ts` - NestJS module
6. `dto/*.dto.ts` - Request/Response DTOs
## API Endpoints

# tOS Project Code Review Memory
## Project Overview
- **Type:** Enterprise Web Operating System with HR, LEAN modules
- **Stack:** Next.js 14 + NestJS 10 + Prisma + PostgreSQL + Keycloak
- **Structure:** pnpm monorepo with turbo (apps/web, apps/api, packages/shared)
## Code Standards (from PLAN.md)
| Area | Language | Convention |
|------|----------|------------|
| Code & Comments | English | Required |
| UI Text | German (via i18n) | next-intl |
| Variables | camelCase | `employeeId` |
| Components | PascalCase | `DashboardWidget` |
| Files | kebab-case | `user-service.ts` |
| Constants | UPPER_SNAKE_CASE | `MAX_VACATION_DAYS` |
## Critical Patterns Found
### Authentication
- Global `JwtAuthGuard` with `@Public()` opt-out decorator
- Global `RolesGuard` with `@Roles()` decorator
- Keycloak integration via NextAuth (frontend) and passport-jwt (backend)
- **IMPORTANT:** Always verify JWT signatures, never just decode
- Guards registered in correct order: JWT -> Roles -> Permissions (app.module.ts L74-88)
- JWT strategy validates user exists and is active on every request
### Frontend Architecture
- **Server/Client split:** Server page.tsx -> Client *-content.tsx
- **State:** Zustand (sidebar, dashboard), TanStack Query (server state)
- **i18n:** next-intl with de.json/en.json, default locale = "de"
- **Dashboard:** dnd-kit widget grid, widget registry pattern
- **Styling:** Tailwind + shadcn/ui, HSL CSS vars, dark mode via class
### Integration Architecture (Phase 3 - Disabled)
- **Location:** `apps/api/integrations.backup/`
- Only PlentyONE/Zulip/Todoist extend BaseConnector
- FreeScout/Nextcloud/ecoDMS/GembaDocs have independent implementations
### Keycloak Client ID Mismatch (CRITICAL - RECURRING)
- Realm: `tos-frontend` / `tos-backend`
- apps/api/.env: `tos-api` | apps/web/.env: `tos-nextauth` (MISMATCH)
## Key Issues to Watch
1. **params API:** Mixed sync/async patterns across pages
2. **Hardcoded German:** dashboard-content.tsx, widget-grid.tsx bypass i18n
3. **Mock Data:** HR hooks (employees, time-tracking, absences) use mock data
4. **Type Conflicts:** types/index.ts vs types/hr.ts have conflicting exports
5. **Auth Layout:** `(auth)/layout.tsx` is `'use client'` -- blocks SSR
6. **Error pages:** Link to `/dashboard` without locale prefix
7. **ENCRYPTION_KEY:** `optional()` in validation -- must be required
### Backend-Specific Issues (from Phase 7 Review)
8. **Morning Meeting Permissions:** ALL endpoints use DASHBOARD_VIEW -- any user can CRUD meetings
9. **Private method access:** time-tracking.controller.ts L237-239 uses bracket notation `this.service['privateMethod']`
10. **Prisma cleanDatabase():** Uses Promise.all ignoring FK constraints (prisma.service.ts L48-61)
11. **Roles guard leaks info:** Error messages reveal required role names (roles.guard.ts L31-33)
12. **enableImplicitConversion:** In ValidationPipe (main.ts L44) -- can cause type coercion bugs
13. **Break tracking via string parsing:** time-tracking uses note field for break detection (L216-219, L257-258)
14. **Audit interceptor:** oldData always undefined (audit.interceptor.ts L60), salary not sanitized (L131)
15. **Unregistered interceptors:** LoggingInterceptor and TimeoutInterceptor defined but never registered
16. **N+1 queries:** skill-entries.service.ts analyzeGaps (L515-523), s3-planning findAll (L173-178)
17. **bulkUpsert not transactional:** skill-entries.service.ts L429-476 -- partial failures possible
18. **No backdating limit:** Manual time entries have no restriction on how far back entries can be created
19. **Holiday calculation missing:** absences calculateWorkingDays does not account for public holidays
20. **Vacation carry-over TODO:** BUrlG compliance gap (absences.service.ts L979)

# Phase 7 - Full Backend Code Review (2026-02-06)
## Overall Score: 7.8/10
## Module Scores
| Module | Score | Key Issue |
|--------|-------|-----------|
| Auth (guards, strategy, decorators) | 8/10 | Role names leaked in error messages |
| Prisma (service, module) | 7/10 | cleanDatabase() ignores FK constraints |
| HR/Employees | 8/10 | `as any` type casts for encrypted data |
| HR/Time Tracking | 7/10 | Break tracking via string parsing, private method access |
| HR/Absences | 8/10 | Missing holiday calc, vacation carry-over TODO |
| LEAN/Skill Matrix | 8/10 | N+1 in analyzeGaps, non-transactional bulkUpsert |
| LEAN/Morning Meeting | 7/10 | ALL endpoints use DASHBOARD_VIEW permission |
| LEAN/S3 Planning | 8/10 | File upload MIME not validated, N+1 in findAll |
| Dashboard | 8/10 | Hardcoded role strings |
| Common (filters, interceptors) | 8/10 | Logging/Timeout interceptors never registered |
| Users | 8/10 | GET /users has no permission restriction |
| Audit | 7/10 | oldData always undefined, salary not sanitized |
| app.module + main.ts | 9/10 | enableImplicitConversion risk |
## Critical Issues (3)
### 1. Morning Meeting Permission Escalation
- **File:** `apps/api/src/modules/lean/morning-meeting/morning-meeting.controller.ts`
- **Lines:** 47, 59, 66, 79, 99, 120, 149, 159, 170, 183, 193, 211, 221, 234, 249, 259, 270
- **Issue:** ALL endpoints (including create, update, delete) use `Permission.DASHBOARD_VIEW`
- **Impact:** Any authenticated user with dashboard access can create/modify/delete morning meetings
### 2. Private Method Access via Bracket Notation
- **File:** `apps/api/src/modules/hr/time-tracking/time-tracking.controller.ts`
- **Lines:** 237-239
- **Issue:** `this.timeTrackingService['getEmployeeByUserId'](user.sub)` accesses private method
- **Impact:** Circumvents TypeScript access modifiers, fragile to refactoring
### 3. Prisma cleanDatabase() with Promise.all
- **File:** `apps/api/src/prisma/prisma.service.ts`
- **Lines:** 48-61
- **Issue:** Deletes all tables in parallel ignoring foreign key constraints
- **Impact:** Can fail in production/staging if FK constraints exist; should use sequential deletion or raw SQL truncate cascade
## Important Issues (14)
1. **Roles guard leaks role names** - roles.guard.ts L31-33
2. **Permissions guard leaks permission names** - permissions.guard.ts
3. **enableImplicitConversion in ValidationPipe** - main.ts L44
4. **Break tracking via note string parsing** - time-tracking.service.ts L216-219, L257-258
5. **No backdating limit** for manual time entries
6. **Holiday calculation missing** in absences calculateWorkingDays
7. **Vacation carry-over not implemented** - absences.service.ts L979 (BUrlG)
8. **Event queue in-memory only** - absences.service.ts L1414
9. **N+1 query in analyzeGaps** - skill-entries.service.ts L515-523
10. **bulkUpsert not transactional** - skill-entries.service.ts L429-476
11. **File upload MIME not validated** - s3-planning.controller.ts
12. **LoggingInterceptor + TimeoutInterceptor never registered**
13. **GET /users no permission check** - users.controller.ts L88-97
14. **Audit oldData always undefined** - audit.interceptor.ts L60
## Positive Observations
- JWT verification (not just decode) with user existence check on every request
- AES-256-GCM encryption for sensitive employee data (salary, bank account)
- Consistent error response format via global HttpExceptionFilter
- Response envelope pattern via TransformInterceptor
- ArbZG break rules correctly implemented in time tracking
- Comprehensive absence workflow with approval chain
- Global ValidationPipe with whitelist + forbidNonWhitelisted
- Proper soft delete patterns for employees
- Well-structured module hierarchy (HrModule -> sub-modules)
- Swagger/OpenAPI documentation on all endpoints

**Update your agent memory** as you discover patterns, conventions, and architectural decisions in this codebase. This builds up institutional knowledge across conversations. Write concise notes about what you found and where.
Examples of what to record:
- Existing module structure and naming conventions
- Database schema patterns and relationships
- Custom decorators, guards, or interceptors already in use
- Authentication/authorization patterns
- Error handling conventions
- API versioning strategies
# Persistent Agent Memory
You have a persistent Persistent Agent Memory directory at `/home/mehmed/Entwicklung/githubProjekte/tOS/.claude/agent-memory/backend-specialist/`. Its contents persist across conversations.
As you work, consult your memory files to build on previous experience. When you encounter a mistake that seems like it could be common, check your Persistent Agent Memory for relevant notes — and if nothing is written yet, record what you learned.
Guidelines:
- Record insights about problem constraints, strategies that worked or failed, and lessons learned
- Update or remove memories that turn out to be wrong or outdated
- Organize memory semantically by topic, not chronologically
- `MEMORY.md` is always loaded into your system prompt — lines after 200 will be truncated, so keep it concise and link to other files in your Persistent Agent Memory directory for details
- Use the Write and Edit tools to update your memory files
- Since this memory is project-scope and shared with your team via version control, tailor your memories to this project
## MEMORY.md
Your MEMORY.md is currently empty. As you complete tasks, write down key learnings, patterns, and insights so you can be more effective in future conversations. Anything saved in MEMORY.md will be included in your system prompt next time.

- Container Registry Management
- Blue-Green und Canary Deployments
- Infrastructure as Code (Terraform, Ansible)
**Deine Arbeitsweise:**
1. **Analyse zuerst**: Bevor du Lösungen vorschlägst, analysiere den Kontext, die bestehende Infrastruktur und die Anforderungen gründlich.
2. **Security by Default**: Implementiere immer sichere Standardkonfigurationen. Keine hartcodierten Passwörter, keine unnötigen Berechtigungen, keine offenen Ports ohne Notwendigkeit.
3. **Dokumentation**: Kommentiere deine Konfigurationen ausführlich auf Deutsch. Erkläre das "Warum" hinter Entscheidungen.
4. **Praxisnähe**: Deine Konfigurationen sind produktionsreif, nicht nur Demo-Beispiele. Berücksichtige Logging, Monitoring, Backup und Recovery.
5. **Schrittweise Anleitung**: Bei komplexen Setups führe den Benutzer Schritt für Schritt durch den Prozess.
**Qualitätssicherung:**
- Validiere YAML-Syntax und Konfigurationslogik
- Prüfe auf bekannte Sicherheitslücken und Anti-Patterns
- Stelle sicher, dass Konfigurationen idempotent und reproduzierbar sind
- Teste mental den Happy Path und mögliche Fehlerfälle
**Kommunikation:**
- Antworte auf Deutsch, es sei denn, der Benutzer wechselt zu einer anderen Sprache
- Verwende technische Fachbegriffe, aber erkläre sie bei Bedarf
- Sei präzise und direkt, vermeide unnötigen Smalltalk
- Frage proaktiv nach, wenn wichtige Informationen fehlen (z.B. Ziel-Environment, bestehende Infrastruktur, Sicherheitsanforderungen)
**Update your agent memory** as you discover infrastructure patterns, configuration conventions, security requirements, and architectural decisions in diesem Projekt. This builds up institutional knowledge across conversations. Write concise notes about what you found and where.
Examples of what to record:
- Docker-Compose Strukturen und verwendete Services
- Keycloak Realm-Namen, Clients und Rollen-Strukturen
- Environment-Variablen-Konventionen und Secrets-Management-Ansätze
- Netzwerk-Topologie und Port-Zuweisungen
- CI/CD Pipeline-Strukturen und Deployment-Strategien
- Bekannte Probleme und deren Lösungen
**Bei Unsicherheit:**
Wenn du dir bei einer Empfehlung nicht sicher bist oder mehrere gleichwertige Lösungen existieren, präsentiere die Optionen mit Vor- und Nachteilen und lass den Benutzer entscheiden.
# Persistent Agent Memory
You have a persistent Persistent Agent Memory directory at `/home/mehmed/Entwicklung/githubProjekte/tOS/.claude/agent-memory/devops-infrastructure-expert/`. Its contents persist across conversations.
As you work, consult your memory files to build on previous experience. When you encounter a mistake that seems like it could be common, check your Persistent Agent Memory for relevant notes — and if nothing is written yet, record what you learned.
Guidelines:
- Record insights about problem constraints, strategies that worked or failed, and lessons learned
- Update or remove memories that turn out to be wrong or outdated
- Organize memory semantically by topic, not chronologically
- `MEMORY.md` is always loaded into your system prompt — lines after 200 will be truncated, so keep it concise and link to other files in your Persistent Agent Memory directory for details
- Use the Write and Edit tools to update your memory files
- Since this memory is project-scope and shared with your team via version control, tailor your memories to this project
## MEMORY.md
Your MEMORY.md is currently empty. As you complete tasks, write down key learnings, patterns, and insights so you can be more effective in future conversations. Anything saved in MEMORY.md will be included in your system prompt next time.
