fix(policy-explorer): handle both PolicySettingRow and PolicySettingSearchResult types

The PolicyDetailSheet component now properly handles both type unions:
- PolicySettingRow (has graphPolicyId) - used in V2
- PolicySettingSearchResult (has id) - used in V1

Uses type guard to check for 'graphPolicyId' property and falls back to 'id' field.
This fixes the TypeScript compilation error in production builds.

+Beschreibung
+-----------
+
+Dieser PR entfernt die Abhängigkeit zu n8n und implementiert ein Code-First Backend.
+
+Infrastructure
+--------------
+
+- Redis Integration & BullMQ Queue Setup.
+
+Worker
+------
+
+- Neuer Background-Worker in `worker/index.ts` (BullMQ `Worker`, concurrency: 1).
+
+Logic
+-----
+
+- Portierung der Policy-Parsing-Logik (Settings Catalog, OMA-URI) nach TypeScript.
+- Graph-Integration (Token-Acquisition, paginierte Fetches) und Retry/Rate-Limit-Handling.
+
+Cleanup
+-------
+
+- Entfernung der alten n8n-API-Endpunkte und Secrets (`app/api/policy-settings/route.ts`, `app/api/admin/tenants/route.ts`, env-variablen entfernt).
+
+Frontend
+--------
+
+- Der "Sync Now" Button triggert jetzt direkt einen BullMQ-Job (Queue: `intune-sync-queue`).
+
+Deployment / Dokploy
+--------------------
+
+- In Dokploy existiert jetzt eine Anwendung `tenantpilot-worker` (`tenantpilot-tenantpilotworker-jomlss`) die auf den Gitea `development` Branch zeigt.
+
+Testing & Notes
+---------------
+
+- Smoke scripts added: `scripts/test-queue-connection.js`, `scripts/test-graph-connection.ts`, `scripts/check-worker-health.js`.
+- Health endpoint: `app/api/worker-health/route.ts` reports queue counts.
+
+Weitere Hinweise
+----------------
+

+# Implementation Plan: Policy Explorer V2
+
+**Branch**: `004-policy-explorer-v2` | **Date**: 2025-12-09 | **Spec**: [spec.md](./spec.md)  
+**Input**: Feature specification from `/specs/004-policy-explorer-v2/spec.md`
+
+## Summary
+
+Upgrade the existing Policy Explorer (`/search`) from basic search/table view to advanced data table with:
+- **Server-side pagination** (10/25/50/100 rows per page)
+- **Multi-column sorting** with ASC/DESC toggle
+- **Column management** (show/hide, resize, reorder) persisted in localStorage
+- **PolicyType filtering** with multi-select checkboxes
+- **Bulk export** (CSV) for selected rows (client-side) and all filtered results (server-side, max 5000)
+- **Enhanced detail view** with copy-to-clipboard, raw JSON, and "Open in Intune" link
+- **URL state** for shareable filtered/sorted views
+- **Sticky header** and compact/comfortable density modes
+
+Technical approach: TanStack Table v8 for client-side table state management, Server Actions for data fetching/export, shadcn/ui primitives for UI consistency, nuqs for URL state, and localStorage for user preferences.
+
+## Technical Context
+
+**Language/Version**: TypeScript 5.x strict mode  
+**Primary Dependencies**:  
+- Next.js 16+ App Router
+- TanStack Table v8 (`@tanstack/react-table`)  
+- Drizzle ORM for database queries  
+- Shadcn UI components  
+- NextAuth.js v4 for tenant isolation  
+- URL state: `nuqs` or native `useSearchParams`  
+- CSV export: `papaparse` or native string builder  
+
+**Storage**: PostgreSQL (existing `policy_settings` table)  
+**Testing**: Jest/Vitest for utils, Playwright for E2E table interactions  
+**Target Platform**: Docker containers, modern web browsers (Chrome, Firefox, Safari, Edge)  
+**Project Type**: Next.js App Router web application  
+**Performance Goals**:  
+- Page load: <500ms (50 rows with filters)  
+- Sorting/filtering: <200ms  
+- CSV export (1000 rows): <2s client-side  
+- CSV export (5000 rows): <5s server-side  
+
+**Constraints**:  
+- Server-first architecture (all data via Server Actions)  
+- No client-side fetching (useEffect + fetch prohibited)  
+- TypeScript strict mode (no `any` types)  
+- Shadcn UI for all components  
+- Azure AD tenant isolation enforced  
+
+**Scale/Scope**: Multi-tenant SaaS, 1000+ policy settings per tenant, 100+ concurrent users
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+- [X] Uses Next.js App Router with Server Actions (pagination/filtering/export via Server Actions)
+- [X] TypeScript strict mode enabled (existing codebase already strict)
+- [X] Drizzle ORM for all database operations (policy settings queries use Drizzle)
+- [X] Shadcn UI for all new components (Table, Button, Sheet, etc.)
+- [X] Azure AD multi-tenant authentication (existing auth, tenant isolation via session)
+- [X] Docker deployment with standalone build (existing Dockerfile)
+
+**Result**: ✅ No constitution violations

+
+## Complexity Tracking
+
+> **No violations** - All constitution checks pass. TanStack Table is a state management library (not a data fetching library), so it complements Server Actions rather than replacing them.
+
+---
+
+## Phase 0: Research & Analysis
+
+### Unknowns to Resolve
+
+1. **TanStack Table Integration Pattern**
+   - **Question**: How to integrate TanStack Table with Next.js Server Actions for server-side pagination/sorting?
+   - **Research**: Review TanStack Table docs for "manual pagination" mode, check existing patterns in similar Next.js projects
+   - **Output**: `research.md` section on TanStack Table + Server Actions integration
+
+2. **CSV Export Strategy**
+   - **Question**: When to use client-side vs server-side CSV generation? What's the performance breakpoint?
+   - **Research**: Test `papaparse` performance with 100/1000/5000 rows, measure memory usage, compare to server-side stream
+   - **Output**: `research.md` section with performance benchmarks and decision matrix
+
+3. **URL State Management**
+   - **Question**: Use `nuqs` library or native `useSearchParams` + `useRouter`?
+   - **Research**: Compare type safety, SSR compatibility, bundle size
+   - **Output**: `research.md` section on URL state library choice
+
+4. **LocalStorage Schema**
+   - **Question**: How to version localStorage schema for forward compatibility when adding new features?
+   - **Research**: Review best practices for localStorage versioning, schema migration patterns
+   - **Output**: `research.md` section on localStorage structure
+
+5. **Sticky Header Implementation**
+   - **Question**: Use CSS `position: sticky` or JavaScript scroll listeners? Performance trade-offs?
+   - **Research**: Test both approaches with large tables (1000+ rows), measure scroll jank
+   - **Output**: `research.md` section on sticky header strategy
+
+### Dependencies & Best Practices
+
+1. **TanStack Table Best Practices**
+   - **Task**: Research recommended patterns for server-side pagination, column definitions, type safety
+   - **Output**: `research.md` section with code examples
+
+2. **Shadcn Table + TanStack Integration**
+   - **Task**: Find examples of shadcn/ui Table primitives used with TanStack Table
+   - **Output**: `research.md` section with integration patterns
+
+3. **CSV Escaping & Edge Cases**
+   - **Task**: Research proper CSV escaping (commas, quotes, newlines), Excel compatibility
+   - **Output**: `research.md` section on CSV generation rules
+
+---
+
+## Phase 1: Design & Contracts
+
+### Data Model Design
+
+**File**: `specs/004-policy-explorer-v2/data-model.md`
+
+#### Entities
+
+**DataTableState** (Client-side ephemeral state)
+```typescript
+interface DataTableState {
+  pagination: {
+    pageIndex: number;        // 0-based
+    pageSize: 10 | 25 | 50 | 100;
+  };
+  sorting: Array<{
+    id: string;               // column ID
+    desc: boolean;            // true = DESC, false = ASC
+  }>;
+  columnVisibility: {
+    [columnId: string]: boolean;
+  };
+  columnSizing: {
+    [columnId: string]: number; // px
+  };
+  rowSelection: {
+    [rowId: string]: boolean;
+  };
+  density: 'compact' | 'comfortable';
+}
+```
+
+**FilterState** (Synced with URL + stored in localStorage)
+```typescript
+interface FilterState {
+  policyTypes: string[];      // ['deviceConfiguration', 'compliancePolicy']
+  searchQuery: string;         // existing search functionality
+  // Future: dateRange, tenant filter (Phase 2)
+}
+```
+
+**TablePreferences** (Persisted in localStorage)
+```typescript
+interface TablePreferences {
+  version: 1;                  // schema version for migrations
+  columnVisibility: { [columnId: string]: boolean };
+  columnSizing: { [columnId: string]: number };
+  columnOrder: string[];       // ordered column IDs
+  density: 'compact' | 'comfortable';
+  defaultPageSize: 10 | 25 | 50 | 100;
+}
+```
+
+#### Database Schema Changes
+
+**None required** - Existing `policy_settings` table has all necessary fields:
+- `policyName`, `policyType`, `settingName`, `settingValue`, `graphPolicyId`, `lastSyncedAt`
+- Indexes already exist for `tenantId`, `settingName`
+- **Recommendation**: Add composite index for sorting performance: `(tenantId, policyType, settingName)`
+
+### API Contracts

+### Quickstart Guide
+
+**File**: `specs/004-policy-explorer-v2/quickstart.md`
+
+```markdown
+# Policy Explorer V2 - Quickstart
+
+## Adding a New Column
+
+1. Define column in `PolicyTableColumns.tsx`:
+   ```typescript
+   {
+     accessorKey: 'myNewField',
+     header: 'My Field',
+     cell: ({ row }) => <span>{row.original.myNewField}</span>,
+   }
+   ```
+
+2. Add to localStorage schema version if changing defaults
+3. Update CSV export to include new column
+
+## Adding a New Filter
+
+1. Update `FilterState` type in `lib/types/policy-table.ts`
+2. Add UI control in `PolicyTableToolbar.tsx`
+3. Update `getPolicySettings` Server Action to handle new filter param
+4. Add to URL state in `useURLState.ts`
+
+## Testing Checklist
+
+- [ ] Pagination: Navigate through pages, verify correct data
+- [ ] Sorting: Click column headers, verify ASC/DESC toggle
+- [ ] Filtering: Select policy types, verify filtered results
+- [ ] Column visibility: Hide/show columns, reload page
+- [ ] CSV export: Export selected rows, verify content
+- [ ] Accessibility: Keyboard navigation, screen reader labels
+```
+
+---
+
+## Phase 1.5: Agent Context Update
+
+**Action**: Run `.specify/scripts/bash/update-agent-context.sh copilot`
+
+This script will:
+1. Detect AI agent in use (Copilot)
+2. Update `.github/copilot-instructions.md`
+3. Add new technologies from this plan:
+   - TanStack Table v8 for data tables
+   - CSV export patterns (client vs server-side)
+   - URL state management with nuqs
+   - LocalStorage persistence patterns
+
+**Manual additions to preserve**:
+- Existing Intune API patterns
+- Project-specific conventions
+
+---
+
+## Re-Evaluation: Constitution Check
+
+*Run after Phase 1 design completion*
+
+- [X] TanStack Table uses Server Actions for data (no client-side fetch)
+- [X] All types strictly defined (DataTableState, FilterState, contracts)
+- [X] Drizzle ORM for queries (no raw SQL)
+- [X] Shadcn UI Table primitives (no custom table components)
+- [X] Azure AD session enforced in Server Actions
+- [X] Docker build unaffected (no new runtime dependencies)
+
+**Result**: ✅ Constitution compliance maintained
+
+---
+
+## Implementation Notes
+
+### Critical Paths
+
+1. **TanStack Table Integration** (Blocking)
+   - Must establish pattern for Server Action + TanStack Table manual pagination
+   - All other features depend on this foundation
+
+2. **Server Action Updates** (Blocking)
+   - `getPolicySettings` must support pagination/sorting before UI can be built
+
+3. **CSV Export** (Parallel after data fetching works)
+   - Client-side export can be built independently
+   - Server-side export requires Server Action
+
+### Parallel Work Opportunities
+
+- **Phase 1**: Data model design + API contracts can happen in parallel
+- **Implementation**: Client-side CSV export + column management can be built while server-side export is in progress
+- **Testing**: Unit tests for utils can be written early, E2E tests require full integration
+
+### Risk Mitigation
+
+**Risk**: TanStack Table performance with large datasets (1000+ rows)
+- **Mitigation**: Use virtualization (`@tanstack/react-virtual`) if needed
+- **Fallback**: Reduce default page size to 25 rows
+
+**Risk**: CSV export memory issues with 5000 rows
+- **Mitigation**: Use streaming approach in Server Action
+- **Fallback**: Reduce max export to 2500 rows
+
+**Risk**: localStorage quota exceeded (5-10MB limit)
+- **Mitigation**: Only store column preferences, not data
+- **Fallback**: Clear old preferences, show user warning
+
+---
+
+## Success Metrics
+
+### Performance Benchmarks
+
+- [ ] Page load (50 rows): <500ms
+- [ ] Sorting operation: <200ms
+- [ ] Filtering operation: <300ms
+- [ ] Column resize: <16ms (60fps)
+- [ ] CSV export (1000 rows, client): <2s
+- [ ] CSV export (5000 rows, server): <5s
+
+### Functional Validation
+
+- [ ] Pagination: All pages load correctly, no duplicate rows
+- [ ] Sorting: Correct order for all column types (string, date, number)
+- [ ] Filtering: AND logic for multiple filters
+- [ ] Column management: Preferences persist across sessions
+- [ ] CSV export: Proper escaping, Excel-compatible
+- [ ] URL state: Shareable links work correctly
+- [ ] Accessibility: Keyboard navigation, ARIA labels
+
+---
+
+## Next Steps
+
+1. **Run Phase 0 Research**:
+   ```bash
+   # Research TanStack Table patterns
+   # Benchmark CSV strategies
+   # Choose URL state library
+   ```

+
+3. **Generate `data-model.md`**:
+   - Define TypeScript interfaces
+   - Document database schema (no changes)
+
+4. **Generate Contracts**:
+   - Create YAML specs for Server Actions
+   - Define input/output types
+
+5. **Update Agent Context**:
+   ```bash
+   .specify/scripts/bash/update-agent-context.sh copilot
+   ```
+
+6. **Generate `tasks.md`**:

+# Feature Specification: Policy Explorer V2
+
+**Feature Branch**: `004-policy-explorer-v2`  
+**Created**: 2025-12-08  
+**Status**: Draft  
+**Input**: "Policy Explorer V2 - Advanced data table with pagination, sorting, filtering, column management, bulk export, and enhanced detail view for Intune policy settings analysis"
+
+## Overview
+
+Erweiterung des bestehenden Policy Explorers (`/search`) von einer einfachen Such-/Tabellenansicht zu einem vollwertigen Admin-Interface für die Analyse großer Policy-Datasets mit erweiterten Funktionen für Navigation, Filterung, Sortierung und Export.
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Advanced Data Table Navigation (Priority: P1)
+
+Als Intune-Admin möchte ich durch große Policy-Datasets navigieren können mit Pagination, Sortierung und anpassbaren Spalten, um schnell relevante Settings zu finden.
+
+**Why this priority**: Grundlegende Tabellenfunktionalität ist essentiell für die Arbeit mit >100 Settings. Ohne Pagination und Sortierung wird die Tabelle unbrauchbar.
+
+**Independent Test**: Dataset mit 500+ Settings laden, Pagination durchklicken, nach verschiedenen Spalten sortieren, Spalten ein-/ausblenden.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Admin hat 200+ Policy Settings im System, **When** er den Policy Explorer öffnet, **Then** sieht er maximal 50 Settings pro Seite mit Pagination Controls (Previous, Next, Page Numbers).
+2. **Given** der Admin sieht die Tabelle, **When** er auf einen Spalten-Header klickt, **Then** wird die Tabelle nach dieser Spalte sortiert (Toggle: ASC/DESC).
+3. **Given** der Admin sieht die Tabelle, **When** er das Column Visibility Menu öffnet und Spalten deselektiert, **Then** werden diese Spalten ausgeblendet und die Einstellung bleibt beim Reload erhalten (localStorage).
+4. **Given** der Admin sieht die Tabelle, **When** er eine Spaltenbreite mit der Maus anpasst, **Then** wird die neue Breite gespeichert (localStorage).
+5. **Given** der Admin scrollt nach unten, **When** er weiter scrollt, **Then** bleibt der Table Header sichtbar (sticky).
+
+---
+
+### User Story 2 - Enhanced Filtering (Priority: P1)
+
+Als Intune-Admin möchte ich nach PolicyType filtern können, um nur relevante Policy-Kategorien zu sehen.
+
+**Why this priority**: Filter sind essentiell für die Arbeit mit verschiedenen Policy-Typen (Compliance, Security, Configuration).
+
+**Independent Test**: PolicyType Filter auswählen, Ergebnisse validieren, Filter kombinieren mit Suche.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Admin öffnet den Policy Explorer, **When** er den PolicyType Filter öffnet, **Then** sieht er alle verfügbaren Policy Types als Checkboxen (deviceConfiguration, compliancePolicy, etc.).
+2. **Given** der Admin hat einen PolicyType ausgewählt, **When** die Tabelle lädt, **Then** werden nur Settings dieses Typs angezeigt.
+3. **Given** der Admin hat Filter + Suche kombiniert, **When** er die Seite neu lädt, **Then** bleiben Filter und Suche aktiv (URL state).
+
+---
+
+### User Story 3 - Bulk Export (Priority: P1)
+
+Als Intune-Admin möchte ich Policy Settings als CSV exportieren können, um sie in Excel/Sheets zu analysieren oder zu dokumentieren.
+
+**Why this priority**: Export ist ein häufig gefordertes Feature für Compliance-Reports und Dokumentation.
+
+**Independent Test**: Rows selektieren, CSV Export triggern, Datei öffnen und Inhalt validieren.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Admin hat Rows in der Tabelle selektiert, **When** er "Export Selected" klickt, **Then** wird ein CSV mit den selektierten Rows heruntergeladen.
+2. **Given** der Admin hat Filter angewendet, **When** er "Export All Filtered" klickt, **Then** wird ein CSV mit allen gefilterten Results heruntergeladen (serverseitig generiert).
+3. **Given** das CSV wurde generiert, **When** der Admin die Datei öffnet, **Then** enthält sie alle relevanten Spalten (Policy Name, Type, Setting Name, Value, Last Synced) mit korrektem CSV-Escaping.
+
+---
+
+### User Story 4 - Enhanced Detail View (Priority: P2)
+
+Als Intune-Admin möchte ich im Detail-Sheet erweiterte Funktionen haben (Copy-to-Clipboard, Raw JSON View), um Settings schnell zu teilen oder zu debuggen.
+
+**Why this priority**: Quality-of-Life Verbesserung für Power-User. Nicht MVP-blocking aber sehr nützlich.
+
+**Independent Test**: Detail-Sheet öffnen, Copy-Buttons testen, Raw JSON Tab öffnen.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Admin öffnet das Detail-Sheet für ein Setting, **When** er auf "Copy Policy ID" klickt, **Then** wird die graphPolicyId in die Zwischenablage kopiert.
+2. **Given** der Admin sieht das Detail-Sheet, **When** er auf "Raw JSON" Tab klickt, **Then** sieht er die kompletten Rohdaten formatiert als JSON.
+3. **Given** das Setting hat eine graphPolicyId, **When** der Admin "Open in Intune" klickt, **Then** öffnet sich ein neues Tab mit dem Intune Portal Link (oder wird Policy ID kopiert als Fallback).
+
+---
+
+### Edge Cases
+
+- Was passiert bei sehr breiten Tabellen (viele Spalten)? → Horizontales Scrolling + Sticky erste Spalte.
+- Wie verhält sich Export bei >10.000 Rows? → Server-seitige Limitierung auf max 5000 Rows pro Export mit Warning.
+- Was passiert wenn keine Rows selektiert sind beim Export? → Button disabled mit Tooltip "Select rows first".
+- Wie wird Sorting mit Pagination kombiniert? → Server-seitig: Sort state wird an API übergeben.
+- Was passiert bei Column Resize auf mobilen Geräten? → Touch-optimierte Resize Handles oder Feature deaktiviert auf <768px.
+

+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes

+- **SC-007**: URL State ist shareable (Copy/Paste URL zeigt identische Filterung).
+- **SC-008**: Detail-Sheet Copy-Buttons funktionieren in allen modernen Browsern (Chrome, Firefox, Safari, Edge).
+
+## Assumptions
+
+- TanStack Table (React Table v8) wird als Data Table Library verwendet.
+- Shadcn UI Table Komponenten werden erweitert oder mit TanStack Table integriert.
+- Export-Logik nutzt serverseitigen Endpoint für große Datasets (>1000 Rows).
+- Column Settings werden im localStorage gespeichert (keine User-Profile Persistierung).
+- "Open in Intune" Links werden per Policy Type konstruiert (bekannte URL-Pattern).
+
+## Nicht-Ziele (Out of Scope)
+
+- Kein Policy Editing (read-only view bleibt erhalten).
+- Kein vollständiges RBAC-System (bleibt bei Tenant-Isolation).
+- Kein Conflict Detection (Phase 2).
+- Kein Policy Comparison/Diff (Phase 2).
+- Kein Saved Views (Phase 2).
+- Keine Gruppierung (Group by Policy/Setting) (Phase 2).
+
+## Technical Notes
+
+### TanStack Table Integration
+
+- `@tanstack/react-table` bereits im Projekt vorhanden oder muss installiert werden
+- Server-side Pagination, Sorting, Filtering via Server Actions
+- Column Definitions mit Type-Safety via TypeScript

+
+### CSV Export Strategy
+
+**Client-Side** (Selected Rows):
+- Library: `papaparse` oder native String-Builder

+
+**Server-Side** (Filtered Results):
+- Neuer Server Action: `exportPolicySettingsCSV(filterState)`
+- Stream-basierter Export für große Datasets
+- Content-Disposition Header für File Download
+- Limit: 5000 Rows (UI Warning bei mehr)
+
+### URL State Management
+
+- `nuqs` Library für type-safe URL State
+- Query Params:
+  - `page`: number
+  - `pageSize`: 10|25|50|100
+  - `sortBy`: columnId
+  - `sortDir`: asc|desc
+  - `policyTypes`: comma-separated
+  - `q`: search query
+
+### Column Configuration
+
+Default Columns:
+- Setting Name (visible, pinned left)
+- Setting Value (visible, truncated)
+- Policy Name (visible)
+- Policy Type (visible, badge)
+- Last Synced (visible, relative time)
+- Policy ID (hidden by default)
+
+## Dependencies
+
+- TanStack Table v8: `@tanstack/react-table`
+- CSV Export: `papaparse` (optional, kann auch nativ gebaut werden)
+- URL State: `nuqs` (optional, kann auch mit useSearchParams gelöst werden)

+    US1 --> Polish[Phase 7: Polish]
+    US2 --> Polish
+    US3 --> Polish
+    US4 --> Polish
+```
+
+**Explanation**:
+- **Setup & Foundation** must complete first (T001-T010)
+- **US1 (Data Table)** is the foundation for all other user stories
+- **US2 (Filtering)** depends on table being functional
+- **US3 (Export)** depends on row selection from US1
+- **US4 (Detail View)** extends existing sheet, can happen in parallel with US2/US3
+- **Polish** comes last after all core features work
+
+### Task-Level Dependencies
+
+**Critical Path** (must complete in order):
+1. T001-T004 (setup) → T005-T010 (Server Actions)
+2. T005-T010 (Server Actions) → T011-T022 (US1 table implementation)
+3. T011-T022 (table) → All other user stories can begin
+4. T031 (row selection) → T033-T037 (export features)
+
+**Parallel Opportunities**:
+- T001, T002, T003, T004 can run in parallel (setup tasks)
+- T005-T010 can run in parallel after T004 (Server Action updates)
+- T011, T012, T013, T014 can run in parallel (hooks and column definitions)
+- T023, T029, T030, T038, T039, T047, T049 can run in parallel after table is functional
+- T054-T058 can run in parallel during polish phase
+
+---
+
+## Parallel Execution Examples
+
+### Phase 1 - Setup (All tasks in parallel)
+Run these tasks simultaneously:
+```bash
+# Terminal 1: Install TanStack Table
+npm install @tanstack/react-table
+
+# Terminal 2: Install nuqs
+npm install nuqs
+
+# Terminal 3: Create types file
+# T003 - Create lib/types/policy-table.ts
+
+# Terminal 4: Add database index
+# T004 - Update schema
+```
+
+### Phase 2 - Server Actions (After T004 completes)
+Run Server Action updates in parallel:
+```bash
+# All T005-T010 modify lib/actions/policySettings.ts
+# Can be done together or split by developer
+# T005-T009: Update getPolicySettings
+# T010: Create exportPolicySettingsCSV
+```
+
+### Phase 3 - US1 Foundation (After Phase 2)
+Run these in parallel:
+```bash
+# Terminal 1: T011 - Column definitions
+# Terminal 2: T012 - usePolicyTable hook
+# Terminal 3: T013 - useTablePreferences hook
+# Terminal 4: T014 - useURLState hook
+```
+
+### Phase 7 - Polish (After Phase 3-6 complete)
+Run tests and polish tasks in parallel:
+```bash
+# Terminal 1: T054-T058 - E2E tests
+# Terminal 2: T047, T048 - Meta info component
+# Terminal 3: T049, T050, T051 - Responsive behavior
+# Terminal 4: T052, T053 - Accessibility
+```

+
+## Implementation Strategy
+
+### MVP Scope (Ship This First)
+**Phase 3: User Story 1 - Advanced Data Table Navigation**
+- This is the core value: pagination, sorting, column management
+- Includes: T011-T022 (12 tasks)
+- **Delivers SC-001, SC-002, SC-003**: Fast pagination, sorting, persistent settings
+- **Can be shipped independently**: Provides immediate value even without filtering/export
+
+### Incremental Delivery
+1. **MVP** (Phase 3): Ship US1 data table → users can navigate large datasets
+2. **V1.1** (Phase 4): Add US2 filtering → users can narrow down results by policy type
+3. **V1.2** (Phase 5): Add US3 export → users can extract data for reports
+4. **V1.3** (Phase 6): Add US4 enhanced detail view → power users get advanced features
+5. **V2.0** (Phase 7): Polish + complete testing → production-ready
+
+### Success Metrics (Track These)
+- **SC-001**: Page load time <500ms (50 rows) → Measure with Lighthouse/DevTools
+- **SC-002**: Sorting performance <200ms → Measure with Performance API
+- **SC-003**: localStorage persistence → Test browser reload, verify settings restored
+- **SC-004**: Client CSV export <2s (1000 rows) → Measure download trigger time
+- **SC-005**: Server CSV export <5s (5000 rows) → Measure Server Action execution time
+- **SC-006**: Filter + search AND logic → Verify result counts match expectations
+- **SC-007**: URL state shareable → Copy URL, paste in new tab, verify identical view
+- **SC-008**: Copy buttons work → Test in Chrome, Firefox, Safari, Edge
+
+---
+
+## Validation Checklist
+
+Before marking tasks complete, verify:
+
+- [ ] All Server Actions have input validation (Zod schemas)
+- [ ] All Server Actions enforce tenant isolation (check user session)
+- [ ] Table pagination works with 0 results, 1 result, 1000+ results
+- [ ] Sorting works correctly for strings, numbers, dates
+- [ ] Column visibility changes persist after browser reload
+- [ ] CSV export handles special characters (commas, quotes, newlines)
+- [ ] CSV export is Excel-compatible (UTF-8 BOM, proper line endings)
+- [ ] URL state works with browser back/forward buttons
+- [ ] Sticky header works on different viewport sizes
+- [ ] Row selection persists across page changes (or clears intentionally)
+- [ ] All interactive elements have keyboard support
+- [ ] All interactive elements have ARIA labels
+- [ ] Loading states show for all async operations
+- [ ] Error states show helpful messages with retry options
+- [ ] TypeScript strict mode passes (no `any` types)
+- [ ] All new components use Shadcn UI primitives
+
+---
+
+## Notes
+
+**About TanStack Table Integration**: 
+- Use "manual" pagination mode (table doesn't handle data fetching)
+- Server Actions fetch data, table handles UI state only
+- This keeps us constitution-compliant (server-first architecture)
+
+**About CSV Export**:
+- Client-side (<1000 rows): Fast, no server load, instant download
+- Server-side (1000-5000 rows): Handles larger datasets, proper memory management
+- Always include CSV header row with column names
+- Use UTF-8 BOM for Excel compatibility: `\uFEFF` prefix
+
+**About localStorage Schema**:
+- Version field enables migrations when adding new preferences
+- Store only user preferences, never actual data
+- Handle quota exceeded gracefully (clear old data, warn user)
+
+**About URL State**:
+- Keep URLs shareable (don't include sensitive data)
+- Use short query param names (p=page, ps=pageSize, sb=sortBy)
+- Handle malformed URLs gracefully (validate and reset to defaults)
+
+**Performance Considerations**:
+- Add database index on (tenantId, policyType, settingName) for sorting
+- Use React.memo on table rows only if profiling shows re-render issues
+- Debounce search input to avoid excessive Server Action calls
+- Consider virtual scrolling if page size >100 causes jank

+
+## Constitution Alignment Issues
+
+**Status**: ✅ **NO VIOLATIONS**
+
+All constitution principles are properly addressed in the plan:
+
+| Principle | Compliance | Evidence |
+|-----------|-----------|----------|
+| I. Server-First Architecture | ✅ | Worker = background Server Action pattern |
+| II. TypeScript Strict Mode | ✅ | All worker code in strict mode (plan.md L79) |
+| III. Drizzle ORM Integration | ✅ | FR-016, T036-T040 |
+| IV. Shadcn UI Components | ✅ | No UI changes (plan.md L81) |
+| V. Azure AD Multi-Tenancy | ✅ | Uses existing Azure AD Client Credentials |
+
+---
+
+## Unmapped Tasks
+
+**Status**: ✅ All tasks mapped to requirements
+
+No orphan tasks found - all 64 tasks trace back to functional requirements or user stories.
+
+---
+
+## Ambiguity Detection
+
+### Vague Language Found
+
+| Location | Term | Issue | Recommendation |
+|----------|------|-------|----------------|
+| spec.md:L182 | "stabil" | Undefined stability metric | Already addressed by SC-007 (1+ hour, 10+ jobs) |
+| spec.md:L199 | "dokumentiert oder nachvollziehbar" | Unclear validation method | Add task to document n8n logic extraction process |
+
+### Unresolved Placeholders
+
+**Status**: ✅ No placeholders found (no TODO, TKTK, ???, `<placeholder>`)
+
+---
+
+## Inconsistency Detection
+
+### Terminology Drift
+
+| Term Variations | Occurrences | Standard Form | Action |
+|-----------------|-------------|---------------|--------|
+| Worker Process / Worker / Background Worker | spec.md (3), plan.md (5), tasks.md (2) | Worker Process | Update all to "Worker Process" |
+| BullMQ / Bull MQ / Job Queue | spec.md (2), tasks.md (1) | BullMQ | Already consistent |
+| Redis / Redis Queue / In-Memory Store | Various | Redis | Already consistent |
+
+### Phase Numbering Mismatch
+
+**Issue**: plan.md uses "Phase 0-8" (9 phases) but tasks.md uses "Phase 1-9" (9 phases)
+
+**Impact**: MEDIUM - Confusing for developers
+
+**Recommendation**: Standardize to "Phase 1-9" in both documents (remove "Phase 0" concept)
+
+### Data Entity Inconsistencies
+
+**Status**: ✅ No conflicts
+
+All entities (SyncJobPayload, GraphPolicyResponse, FlattenedSetting) consistently defined.
+
+---
+
+## Duplication Detection
+
+### Near-Duplicate Requirements
+
+**Status**: ✅ No duplicates found
+
+All 26 functional requirements are distinct and non-overlapping.
+
+### Redundant Tasks
+
+| Task Pair | Similarity | Analysis | Action |
+|-----------|----------|----------|--------|
+| T003 + T004 | Both update lib/env.mjs | Intentional (schema vs runtime) | Keep separate |
+| T049-T050 + T051-T054 | All remove env vars | Intentional (different locations) | Keep separate |
+
+---
+
+## Underspecification Issues
+
+### Requirements Missing Measurable Criteria
+
+| Requirement | Issue | Recommendation |
+|-------------|-------|----------------|
+| FR-009 | "max 3 Versuche" - no backoff timing specified | Add to technical-notes.md (already present) |
+| FR-013 | Humanization rules not fully specified | Acceptable - examples provided, edge cases handled in code |
+
+### User Stories Missing Acceptance Criteria
+
+**Status**: ✅ All user stories have 5 acceptance scenarios each
+
+### Tasks with No Validation
+
+| Task | Issue | Recommendation |
+|------|-------|----------------|
+| T011 | Worker event handlers - no validation criteria | Add validation: "Verify logs appear for completed/failed/error events" |
+| T012 | Structured logging - format not specified | Add validation: "Verify JSON format with required fields (event, jobId, timestamp)" |
+
+---

+
+### OPTIONAL (Nice to Have)
+
+7. Add validation criteria to T011 and T012
+8. Document n8n logic extraction process (for "nachvollziehbar" assumption)
+
+---
+
+## Implementation Status
+
+✅ **READY FOR IMPLEMENTATION**
+
+All medium-priority issues resolved. Feature 005 is ready for Phase 1 implementation (T001-T008: Setup & Infrastructure).
+
+---
+
+## Remediation Suggestions
+
+### Fix A1: Task Count Header
+
+**File**: `specs/005-backend-arch-pivot/tasks.md`
+
+**Line 4**: Change from:
+```markdown
+**Total Tasks**: 49
+```
+
+To:
+```markdown
+**Total Tasks**: 64
+```
+
+---
+
+### Fix D2: Phase Numbering
+
+**Option 1** (Recommended): Rename "Phase 0" to "Phase 1" in plan.md
+
+**Option 2**: Rename "Phase 1" to "Phase 0" in tasks.md
+
+**Recommendation**: Use Option 1 (start with Phase 1 for consistency with task numbering)
+
+---
+
+## Conclusion
+
+**Overall Quality**: HIGH
+
+**Readiness**: ✅ **READY FOR IMPLEMENTATION** after addressing 3 medium-priority issues
+
+**Strengths**:
+- 100% requirement coverage
+- 100% user story coverage  
+- Zero constitution violations
+- Clear traceability from spec → plan → tasks
+- Comprehensive technical notes
+- Well-defined success criteria
+
+**Weaknesses**:
+- Minor task count discrepancy (easily fixable)

+- Some terminology drift (non-blocking)
+
+**Risk Assessment**: LOW - Issues are documentation-only, no architectural or design flaws detected.
+
+---
+
+**Report Status**: ✅ Complete  
+**Next Step**: Address 3 medium-priority fixes, then proceed with implementation

+# Implementation Plan: Backend Architecture Pivot
+
+**Feature Branch**: `005-backend-arch-pivot`  
+**Created**: 2025-12-09  
+**Spec**: [spec.md](./spec.md)  
+**Status**: Ready for Implementation

+
+## Executive Summary
+
+**Goal**: Migrate from n8n Low-Code backend to TypeScript Code-First backend with BullMQ job queue for Policy synchronization.
+
+**Impact**: Removes external n8n dependency, improves maintainability, enables AI-assisted refactoring, and provides foundation for future scheduled sync features.
+
+**Complexity**: HIGH - Requires new infrastructure (Redis, BullMQ), worker process deployment, and careful data transformation logic porting.
+
+---
+
+## Technical Context
+
+### Current Architecture (n8n-based)
+
+```
+User clicks "Sync Now"
+    ↓
+Server Action: triggerPolicySync()
+    ↓
+HTTP POST → n8n Webhook (N8N_SYNC_WEBHOOK_URL)
+    ↓
+n8n Workflow:
+  1. Microsoft Graph Authentication
+  2. Fetch Policies (4 endpoints with pagination)
+  3. JavaScript Code Node: Deep Flattening Logic
+  4. HTTP POST → TenantPilot Ingestion API
+    ↓
+API Route: /api/policy-settings (validates POLICY_API_SECRET)
+    ↓
+Drizzle ORM: Insert/Update policy_settings table
+```
+
+**Problems**:
+- External dependency (n8n instance required)
+- Complex transformation logic hidden in n8n Code Node
+- Hard to test, version control, and refactor
+- No AI assistance for n8n code
+- Additional API security layer needed (POLICY_API_SECRET)
+
+### Target Architecture (BullMQ-based)
+
+```
+User clicks "Sync Now"
+    ↓
+Server Action: triggerPolicySync()
+    ↓
+BullMQ: Add job to Redis queue "intune-sync-queue"
+    ↓
+Worker Process (TypeScript):
+  1. Microsoft Graph Authentication (@azure/identity)
+  2. Fetch Policies (4 endpoints with pagination)
+  3. TypeScript: Deep Flattening Logic
+  4. Drizzle ORM: Direct Insert/Update
+    ↓
+Database: policy_settings table
+```
+
+**Benefits**:
+- No external dependencies (Redis only)
+- All logic in TypeScript (version-controlled, testable)
+- AI-assisted refactoring possible
+- Simpler security model (no API bridge)
+- Foundation for scheduled syncs
+
+---
+
+## Constitution Check *(mandatory)*
+
+### Compliance Verification
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| **I. Server-First Architecture** | ✅ COMPLIANT | Worker uses Server Actions pattern (background job processing), no client fetches |
+| **II. TypeScript Strict Mode** | ✅ COMPLIANT | All worker code in TypeScript strict mode, fully typed Graph API responses |
+| **III. Drizzle ORM Integration** | ✅ COMPLIANT | Worker uses Drizzle for all DB operations, no raw SQL |
+| **IV. Shadcn UI Components** | ✅ COMPLIANT | No UI changes (frontend only triggers job, uses existing components) |
+| **V. Azure AD Multi-Tenancy** | ✅ COMPLIANT | Uses existing Azure AD Client Credentials for Graph API access |
+
+### Risk Assessment
+
+**HIGH RISK**: Worker deployment as separate process (requires Docker Compose update, PM2/Systemd config)
+
+**MEDIUM RISK**: Graph API rate limiting handling (needs robust retry logic)
+
+**LOW RISK**: BullMQ integration (well-documented library, standard Redis setup)
+
+### Justification
+
+Architecture pivot necessary to:
+1. Remove external n8n dependency (reduces operational complexity)
+2. Enable AI-assisted development (TypeScript vs. n8n visual flows)
+3. Improve testability (unit/integration tests for worker logic)
+4. Prepare for Phase 2 features (scheduled syncs, multi-tenant parallel processing)
+
+**Approved**: Constitution compliance verified, complexity justified by maintainability gains.

+
+## Phase Breakdown
+
+### Phase 1: Setup & Infrastructure (T001-T008)
+
+**Goal**: Prepare environment, install dependencies, and wire the app to the provisioned Redis instance
+
+**Tasks**:
+- T001: Confirm `REDIS_URL` is provided by Dokploy and obtain connection details
+- T002-T004: Add `REDIS_URL` to local `.env` (for development) and to `lib/env.mjs` runtime validation
+- T005: Install npm packages: `bullmq`, `ioredis`, `@azure/identity`, `tsx`
+- T006-T007: Create Redis connection and BullMQ Queue
+- T008: Test infrastructure (connect to provided Redis from local/dev environment)
+
+**Deliverables**:
+- Connection details for Redis from Dokploy documented
+- Environment variables validated (local + deploy)
+- Dependencies in `package.json`
+- Queue operational using the provided Redis
+
+**Exit Criteria**: `npm run dev` starts without env validation errors and the queue accepts jobs against the provided Redis
+
+---
+
+### Phase 2: Worker Process Skeleton (T009-T014)ntry point and basic job processing infrastructure
+
+**Tasks**:
+- T009: Create `worker/index.ts` - BullMQ Worker entry point
+- T010-T012: Add npm script, event handlers, structured logging
+- T013: Create sync orchestration skeleton
+- T014: Test worker startup
+
+**Deliverables**:
+- Worker process can be started via `npm run worker:start`
+- Jobs flow from queue → worker
+- Event logging operational
+
+**Exit Criteria**: Worker logs "Processing job X" when job is added to queue
+
+---
+
+### Phase 3: Microsoft Graph Integration (T015-T023)ion and Microsoft Graph API data fetching with pagination
+
+**Tasks**:
+- T015-T017: Create `worker/jobs/graphAuth.ts` - Azure AD token acquisition
+- T018-T021: Create `worker/jobs/graphFetch.ts` - Fetch from 4 endpoints with pagination
+- T022: Create `worker/utils/retry.ts` - Exponential backoff
+- T023: Test with real tenant data
+
+**Deliverables**:
+- `getGraphAccessToken()` returns valid token
+- `fetchAllPolicies()` returns all policies from 4 endpoints
+- Pagination handled correctly (follows `@odata.nextLink`)
+- Rate limiting handled with retry
+
+**Exit Criteria**: Worker successfully fetches >50 policies for test tenant
+
+---
+
+### Phase 4: Data Transformation (T024-T035)
+
+**Goal**: Port n8n flattening logic to TypeScript
+
+**Tasks**:
+1. Create `worker/jobs/policyParser.ts` - Policy type detection & routing
+2. Implement Settings Catalog parser (`settings[]` → flat key-value)
+3. Implement OMA-URI parser (`omaSettings[]` → flat key-value)
+4. Create `worker/utils/humanizer.ts` - Setting ID humanization
+5. Handle empty policies (default placeholder setting)
+6. Test: Parse sample policies, verify output structure
+
+**Deliverables**:
+- `parsePolicySettings()` converts Graph response → FlattenedSetting[]
+- Humanizer converts technical IDs → readable names
+- Empty policies get "(No settings configured)" entry
+
+**Exit Criteria**: 95%+ of sample settings are correctly extracted and formatted
+
+---
+
+### Phase 5: Database Persistence (T036-T043)
+
+**Goal**: Implement Drizzle ORM upsert logic
+
+**Tasks**:
+1. Create `worker/jobs/dbUpsert.ts` - Batch upsert with conflict resolution
+2. Use existing `policy_settings` table schema
+3. Leverage `policy_settings_upsert_unique` constraint (tenantId + graphPolicyId + settingName)
+4. Update `lastSyncedAt` on every sync
+5. Test: Run full sync, verify data in DB
+
+**Deliverables**:
+- `upsertPolicySettings()` inserts new & updates existing settings
+- No duplicate settings created
+- `lastSyncedAt` updated correctly
+
+**Exit Criteria**: Full sync for test tenant completes successfully, data visible in DB
+
+---
+
+### Phase 6: Frontend Integration (T044-T051)
+
+**Goal**: Replace n8n webhook with BullMQ job creation
+
+**Tasks**:
+1. Modify `lib/actions/policySettings.ts` → `triggerPolicySync()`
+2. Remove n8n webhook call (`fetch(env.N8N_SYNC_WEBHOOK_URL)`)
+3. Replace with BullMQ job creation (`syncQueue.add(...)`)
+4. Return job ID to frontend
+5. Test: Click "Sync Now", verify job created & processed
+
+**Deliverables**:
+- "Sync Now" button triggers BullMQ job
+- User sees immediate feedback (no blocking)
+- Worker processes job in background
+
+**Exit Criteria**: End-to-end sync works from UI → Queue → Worker → DB
+
+---
+
+### Phase 7: Legacy Cleanup (T052-T056)
+
+**Goal**: Remove all n8n-related code and configuration
+
+**Tasks**:
+1. Delete `app/api/policy-settings/route.ts` (n8n ingestion API)
+2. Delete `app/api/admin/tenants/route.ts` (n8n polling API)
+3. Remove `POLICY_API_SECRET` from `.env` and `lib/env.mjs`
+4. Remove `N8N_SYNC_WEBHOOK_URL` from `.env` and `lib/env.mjs`
+5. Grep search for remaining references (should be 0)
+6. Update documentation (remove n8n setup instructions)
+
+**Deliverables**:
+- No n8n-related files in codebase
+- No n8n-related env vars
+- Clean grep search results
+
+**Exit Criteria**: `grep -r "POLICY_API_SECRET\|N8N_SYNC_WEBHOOK_URL" .` returns 0 results (excluding specs/)
+
+---
+
+### Phase 8: Testing & Validation (T057-T061)
+
+**Goal**: Comprehensive testing of new architecture
+
+**Tasks**:
+1. Unit tests for flattening logic
+2. Integration tests for worker jobs
+3. End-to-end test: UI → Queue → Worker → DB
+4. Load test: 100+ policies sync
+5. Error handling test: Graph API failures, Redis unavailable
+6. Memory leak test: Worker runs 1+ hour with 10+ jobs
+
+**Deliverables**:
+- Test suite with >80% coverage for worker code
+- All edge cases verified
+- Performance benchmarks met (SC-001 to SC-008)
+
+**Exit Criteria**: All tests pass, no regressions in existing features
+
+---
+
+### Phase 9: Deployment (T062-T066)
+
+**Goal**: Deploy worker process to production
+
+**Tasks**:
+1. Ensure `REDIS_URL` is set in production (provided by Dokploy) — no Docker Compose Redis required
+2. Configure worker as background service (PM2, Systemd, or Docker)
+3. Set `REDIS_URL` in production environment
+4. Monitor worker logs for first production sync
+5. Verify sync completes successfully
+6. Document worker deployment process
+
+**Deliverables**:
+- Worker running as persistent service
+- Redis accessible from worker
+- Production sync successful
+
+**Exit Criteria**: Production sync works end-to-end, no errors in logs
+
+---
+
+## Key Technical Decisions
+
+### 1. BullMQ vs. Other Queue Libraries
+
+**Decision**: Use BullMQ
+
+**Rationale**:
+- Modern, actively maintained (vs. Kue, Bull)
+- TypeScript-first design
+- Built-in retry, rate limiting, priority queues
+- Excellent documentation
+- Redis-based (simpler than RabbitMQ/Kafka)
+
+**Alternatives Considered**:
+- **Bee-Queue**: Lighter but less features
+- **Agenda**: MongoDB-based (adds extra dependency)
+- **AWS SQS**: Vendor lock-in, requires AWS setup
+
+---
+
+### 2. Worker Process Architecture
+
+**Decision**: Single worker process, sequential job processing (concurrency: 1)
+
+**Rationale**:
+- Simpler implementation (no race conditions)
+- Microsoft Graph rate limits per tenant
+- Database upsert logic easier without concurrency
+- Can scale later if needed (multiple workers)
+
+**Alternatives Considered**:
+- **Parallel Processing**: Higher complexity, potential conflicts
+- **Lambda/Serverless**: Cold starts, harder debugging
+
+---
+
+### 3. Token Acquisition Strategy
+
+**Decision**: Use `@azure/identity` ClientSecretCredential
+
+**Rationale**:
+- Official Microsoft library
+- Handles token refresh automatically
+- TypeScript support
+- Simpler than manual OAuth flow
+
+**Alternatives Considered**:
+- **Manual fetch()**: More code, error-prone
+- **MSAL Node**: Overkill for server-side client credentials
+
+---
+
+### 4. Flattening Algorithm
+
+**Decision**: Port n8n logic 1:1 initially, refactor later
+
+**Rationale**:
+- Minimize risk (proven logic)
+- Faster migration (no re-design needed)
+- Can optimize in Phase 2 after validation
+
+**Alternatives Considered**:
+- **Re-design from scratch**: Higher risk, longer timeline
+
+---
+
+### 5. Database Schema Changes
+
+**Decision**: No schema changes needed
+
+**Rationale**:
+- Existing `policy_settings` table has required fields
+- UNIQUE constraint already supports upsert logic
+- `lastSyncedAt` field exists for tracking
+
+**Alternatives Considered**:
+- **Add job tracking table**: Overkill for MVP (BullMQ handles this)

+```
+
+**Remove**:
+```bash
+# Delete these lines:
+POLICY_API_SECRET=...
+N8N_SYNC_WEBHOOK_URL=...
+```
+
+### Updated `lib/env.mjs`
+

+    STRIPE_SECRET_KEY: process.env.STRIPE_SECRET_KEY,
+    // ... other vars
+  },
+});
+```
+
+---
+
+## Testing Strategy
+
+### Unit Tests
+
+**Target Coverage**: 80%+ for worker code
+
+**Files to Test**:
+- `worker/utils/humanizer.ts` - Setting ID transformation
+- `worker/jobs/policyParser.ts` - Flattening logic
+- `worker/utils/retry.ts` - Backoff algorithm
+
+**Example**:
+```typescript
+describe('humanizeSettingId', () => {
+  it('removes vendor prefix', () => {
+    expect(humanizeSettingId('device_vendor_msft_policy_config_wifi'))
+      .toBe('Wifi');
+  });
+});
+```
+
+---
+
+### Integration Tests
+
+**Target**: Full worker job processing
+
+**Scenario**:
+1. Mock Microsoft Graph API responses
+2. Add job to queue
+3. Verify worker processes job
+4. Check database for inserted settings
+
+**Example**:
+```typescript
+describe('syncPolicies', () => {
+  it('fetches and stores policies', async () => {
+    await syncPolicies('test-tenant-123');
+    const settings = await db.query.policySettings.findMany({
+      where: eq(policySettings.tenantId, 'test-tenant-123'),
+    });
+    expect(settings.length).toBeGreaterThan(0);
+  });
+});
+```
+
+---
+
+### End-to-End Test
+
+**Scenario**:
+1. Start Redis + Worker
+2. Login to UI
+3. Navigate to `/search`
+4. Click "Sync Now"
+5. Verify:
+   - Job created in Redis
+   - Worker picks up job
+   - Database updated
+   - UI shows success message
+
+---
+
+## Rollback Plan
+
+**If migration fails in production**:
+
+1. **Immediate**: Revert to previous Docker image (with n8n integration)
+2. **Restore env vars**: Re-add `POLICY_API_SECRET` and `N8N_SYNC_WEBHOOK_URL`
+3. **Verify**: n8n webhook accessible, sync works
+4. **Post-mortem**: Document failure reason, plan fixes
+
+**Data Safety**: No data loss risk (upsert logic preserves existing data)
+
+---
+
+## Performance Targets
+
+Based on Success Criteria (SC-001 to SC-008):
+
+| Metric | Target | Measurement |
+|--------|--------|-------------|
+| Job Creation | <200ms | Server Action response time |
+| Sync Duration (50 policies) | <30s | Worker job duration |
+| Setting Extraction | >95% | Manual validation with sample data |
+| Worker Stability | 1+ hour, 10+ jobs | Memory profiling |
+| Pagination | 100% | Test with 100+ policies tenant |
+

+    "completed": 45,
+    "failed": 3
+  }
+}
+```
+
+**Use Case**: Monitoring dashboard, uptime checks
+
+---
+
+## Documentation Updates
+
+**Files to Update**:
+1. `README.md` - Add worker deployment instructions
+2. `DEPLOYMENT.md` - Document Redis setup, worker config
+3. `specs/002-manual-policy-sync/` - Mark as superseded by 005

+
+## Open Questions & Risks
+
+### Q1: Redis Hosting Strategy
+
+**Question**: Self-hosted Redis or managed service (e.g., Upstash, Redis Cloud)?
+
+**Options**:
+- Docker Compose (simple, dev-friendly)
+- Upstash (serverless, paid but simple)
+- Self-hosted on VPS (more control, more ops)
+
+**Recommendation**: Start with Docker Compose, migrate to managed service if scaling needed
+
+---
+
+### Q2: Worker Deployment Method
+
+**Question**: How to deploy worker in production?
+
+**Options**:
+- PM2 (Node process manager)
+- Systemd (Linux service)
+- Docker container (consistent with app)
+
+**Recommendation**: Docker container (matches Next.js deployment strategy)
+
+---
+
+### Q3: Job Failure Notifications
+
+**Question**: How to notify admins when sync jobs fail?
+
+**Options**:
+- Email via Resend (already integrated)
+- In-app notification system (Phase 2)
+- External monitoring (e.g., Sentry)
+
+**Recommendation**: Start with logs only, add notifications in Phase 2
+

+# Feature Specification: Backend Architecture Pivot
+
+**Feature Branch**: `005-backend-arch-pivot`  
+**Created**: 2025-12-09  
+**Status**: Draft  
+**Input**: "Backend Architecture Pivot (n8n Removal & BullMQ Implementation) - Remove n8n legacy code, implement BullMQ job queue with Redis, port sync logic to TypeScript worker"
+
+## Overview
+
+Migration von einer Low-Code-Backend-Architektur (n8n) zu einem Code-First-Backend mit BullMQ Job Queue und TypeScript Worker. Die komplexe Microsoft Graph Synchronisations-Logik wird direkt in TypeScript implementiert, um Wartbarkeit, Testbarkeit und AI-gestütztes Refactoring zu maximieren.
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Manual Policy Sync via Queue (Priority: P1)
+
+Als Intune-Admin möchte ich auf "Sync Now" klicken und erwarten, dass die Synchronisation asynchron in einem Worker-Prozess ausgeführt wird, damit die UI nicht blockiert und ich sofort weiterarbeiten kann.
+
+**Why this priority**: Core-Funktionalität - ohne funktionierenden Sync ist das gesamte Feature unbrauchbar. Queue-basierte Architektur ist Grundlage für spätere Scheduled Syncs.
+
+**Independent Test**: Click "Sync Now", check Redis for job, observe worker logs, verify database updates.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Admin ist auf `/search` eingeloggt, **When** er auf "Sync Now" klickt, **Then** wird ein Job in die Redis Queue eingestellt (keine Wartezeit für den User).
+2. **Given** ein Sync-Job wurde erstellt, **When** der Worker-Prozess läuft, **Then** nimmt er den Job aus der Queue und beginnt die Synchronisation.
+3. **Given** der Worker führt einen Sync aus, **When** die Synchronisation erfolgreich abgeschlossen ist, **Then** werden alle Policy Settings in der Datenbank aktualisiert (Insert oder Update via `onConflictDoUpdate`).
+4. **Given** der Worker synchronisiert Policies, **When** ein Fehler auftritt (z.B. Graph API Timeout), **Then** wird der Job in einen "failed" State versetzt und der Fehler wird geloggt (kein Silent Fail).
+5. **Given** der Admin hat mehrere Sync-Jobs gestartet, **When** der Worker mehrere Jobs in der Queue findet, **Then** werden sie sequenziell abgearbeitet (keine parallelen Syncs pro Tenant).
+
+---
+
+### User Story 2 - Microsoft Graph Data Fetching (Priority: P1)
+
+Als System möchte ich alle relevanten Policy-Typen von Microsoft Graph API abrufen können (Device Configurations, Compliance Policies, Configuration Policies, Intents), damit alle Intune-Settings analysierbar sind.
+
+**Why this priority**: Datenbeschaffung ist essentiell - ohne vollständigen Fetch fehlen Policies in der Analyse.
+
+**Independent Test**: Run worker with test tenant, verify all policy types are fetched, check pagination handling.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Worker startet einen Sync, **When** er ein Access Token anfordert, **Then** nutzt er den Azure AD Client Credentials Flow mit `AZURE_AD_CLIENT_ID` und `AZURE_AD_CLIENT_SECRET`.
+2. **Given** der Worker hat ein gültiges Token, **When** er Policies abruft, **Then** fetcht er alle relevanten Endpoints:
+   - `/deviceManagement/deviceConfigurations`
+   - `/deviceManagement/deviceCompliancePolicies`
+   - `/deviceManagement/configurationPolicies`
+   - `/deviceManagement/intents`
+3. **Given** eine Graph API Response hat `@odata.nextLink`, **When** der Worker die Response verarbeitet, **Then** folgt er dem Link und lädt alle Seiten bis keine `nextLink` mehr vorhanden ist.
+4. **Given** ein Policy Object wird von Graph zurückgegeben, **When** der Worker es parst, **Then** extrahiert er `id`, `displayName`, `@odata.type`, `lastModifiedDateTime` und Policy-spezifische Settings.
+5. **Given** der Graph API Call schlägt fehl (401, 429, 500), **When** der Fehler auftritt, **Then** wird ein Retry mit Exponential Backoff durchgeführt (max 3 Versuche).
+
+---
+
+### User Story 3 - Deep Flattening & Data Transformation (Priority: P1)
+
+Als System möchte ich komplexe verschachtelte Policy-Objekte in flache Key-Value-Paare transformieren können, damit sie in der `policy_settings` Tabelle gespeichert und durchsucht werden können.
+
+**Why this priority**: Core Transformation Logic - ohne Flattening können verschachtelte Settings nicht analysiert werden.
+
+**Independent Test**: Run parser with sample Graph responses, verify flattened output matches expected structure.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Worker hat Policy-Daten von Graph erhalten, **When** er ein Settings Catalog Policy verarbeitet (`#microsoft.graph.deviceManagementConfigurationPolicy`), **Then** iteriert er über `settings[]` und extrahiert `settingDefinitionId` und `value`.
+2. **Given** ein Policy enthält verschachtelte Objekte (z.B. `value.simple.value` oder `value.children[]`), **When** der Flattening-Algorithmus läuft, **Then** wird jede verschachtelte Ebene mit Dot-Notation als Key dargestellt (z.B. `wifi.ssid.value`).
+3. **Given** der Worker verarbeitet ein OMA-URI Policy, **When** er `omaSettings[]` findet, **Then** extrahiert er `omaUri` als Setting Name und `value` als Setting Value.
+4. **Given** ein Setting Key enthält technische Bezeichner (z.B. `device_vendor_msft_policy_config_wifi_allowwifihotspotreporting`), **When** der Humanizer läuft, **Then** werden Keys in lesbare Form umgewandelt (z.B. `Allow WiFi Hotspot Reporting`).
+5. **Given** ein Policy hat keine Settings (leeres Array), **When** der Worker es verarbeitet, **Then** wird trotzdem ein Eintrag erstellt mit `settingName: "(No settings configured)"` (damit Policy in UI sichtbar ist).
+
+---
+
+### User Story 4 - Legacy Code Removal (Priority: P1)
+
+Als Entwickler möchte ich alle n8n-spezifischen Artefakte entfernen können, damit der Code sauber und wartbar bleibt.
+
+**Why this priority**: Technical Debt Reduction - alte Bridge-APIs verursachen Confusion und Maintenance-Overhead.
+
+**Independent Test**: Search codebase for n8n references, verify all removed, check env validation.
+
+**Acceptance Scenarios**:
+
+1. **Given** der Code wird überprüft, **When** nach `POLICY_API_SECRET` gesucht wird, **Then** existieren keine Referenzen mehr (weder in `.env`, noch in `lib/env.mjs`, noch in Code).
+2. **Given** der Code wird überprüft, **When** nach `N8N_SYNC_WEBHOOK_URL` gesucht wird, **Then** existieren keine Referenzen mehr.
+3. **Given** das Routing wird analysiert, **When** nach `/api/policy-settings/route.ts` gesucht wird, **Then** existiert die Datei nicht mehr (gelöscht).
+4. **Given** das Routing wird analysiert, **When** nach `/api/admin/tenants/route.ts` gesucht wird, **Then** existiert die Datei nicht mehr (gelöscht).
+5. **Given** ein Entwickler startet die App, **When** die Umgebungsvariablen validiert werden, **Then** werden `POLICY_API_SECRET` und `N8N_SYNC_WEBHOOK_URL` nicht mehr als erforderlich markiert.
+
+---
+
+### Edge Cases
+
+- Was passiert wenn Redis nicht erreichbar ist beim Job-Erstellen? → Fehler werfen mit User-Feedback "Sync service unavailable".
+- Was passiert wenn der Worker abstürzt während eines Jobs? → BullMQ Recovery: Job bleibt in "active" state und wird nach Timeout in "failed" verschoben.
+- Wie gehen wir mit Rate Limiting von Microsoft Graph um? → Exponential Backoff + Retry (max 3x), dann Job als "failed" markieren mit Retry-Option.
+- Was passiert bei parallelen Sync-Requests für denselben Tenant? → Queue stellt sicher, dass Jobs sequenziell abgearbeitet werden (kein Concurrency Issue).
+- Wie werden transiente Netzwerkfehler behandelt? → Retry-Logik mit Backoff, nur permanente Fehler (401, 403) führen zu sofortigem Fail.
+- Was passiert mit bestehenden Policy Settings während eines Syncs? → `onConflictDoUpdate` updated bestehende Einträge basierend auf `(tenantId, graphPolicyId, settingName)` Constraint.
+

+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: User erhält sofortige Bestätigung nach Click auf "Sync Now" (<200ms Response Zeit, kein Warten auf Sync-Completion).
+- **SC-002**: Sync für einen Tenant mit 50 Policies ist innerhalb von 30 Sekunden abgeschlossen.
+- **SC-003**: System lädt alle verfügbaren Policies vollständig (auch bei >100 Policies mit mehreren Datenseiten).
+- **SC-004**: Mindestens 95% aller Policy Settings werden korrekt extrahiert und gespeichert (validiert mit repräsentativen Sample-Daten).
+- **SC-005**: Bei temporären Fehlern (z.B. Service-Überlastung) erfolgt automatische Wiederholung (keine manuellen Eingriffe nötig).
+- **SC-006**: Alte Bridge-Komponenten sind vollständig entfernt (keine toten Code-Pfade oder ungenutzten APIs).
+- **SC-007**: Sync-Prozess läuft stabil über längere Zeiträume (1+ Stunde mit 10+ Sync-Operationen ohne Abstürze).
+- **SC-008**: Re-Sync aktualisiert bestehende Daten korrekt ohne Duplikate oder Datenverluste.
+
+## Assumptions
+
+- System nutzt asynchrone Job-Verarbeitung mit Queue-basierter Architektur für Skalierbarkeit.
+- TenantPilot hat bereits Azure AD Multi-Tenant Authentication konfiguriert (Client Credentials verfügbar).
+- Die bestehende `policy_settings` Datenbank-Tabelle hat bereits einen UNIQUE Constraint auf `(tenantId, graphPolicyId, settingName)`.
+- Die Flattening-Logik aus der bisherigen n8n-Implementation ist dokumentiert oder nachvollziehbar.
+- Sync-Prozess wird in Production als persistenter Background-Service betrieben (nicht nur bei Bedarf gestartet).
+- Redis oder vergleichbarer In-Memory Store ist verfügbar für Job Queue Management.
+
+## Nicht-Ziele (Out of Scope)
+
+- Kein automatischer Scheduled Sync (zeitbasierte Trigger) in diesem Feature - bleibt manuelle Auslösung.
+- Keine Web-UI für Job-Management oder Queue-Monitoring.
+- Keine Live-Progress-Updates im Frontend während Sync läuft (kein Echtzeit-Status).
+- Keine parallele Verarbeitung mehrerer Tenants gleichzeitig (sequenzielle Abarbeitung).
+- Keine erweiterten Retry-Strategien oder Dead Letter Queues in MVP.
+- Kein Policy Change Detection oder Diff-Berechnung (nur vollständiger Sync + Update bestehender Daten).
+
+## Technical Notes
+
+**Note**: Detaillierte Implementierungs-Details (Code-Beispiele, API-Calls, Architektur-Patterns) werden in einem separaten Technical Design Document oder im Planning-Phase dokumentiert. Diese Spec fokussiert sich auf das **WAS** und **WARUM**, nicht auf das **WIE**.
+
+### High-Level Architecture Overview
+
+**Queue-Based Sync Architecture**:
+- Asynchrone Job-Verarbeitung für nicht-blockierende User Experience
+- Worker-Prozess als separater Service für Sync-Operationen
+- Persistente Job-Queue für Reliability und Retry-Fähigkeit
+
+**Data Flow**:
+1. User triggers sync → Job wird in Queue eingestellt
+2. Worker nimmt Job aus Queue → Authentifiziert sich bei Microsoft
+3. Worker fetcht Policy-Daten → Transformiert & flacht verschachtelte Strukturen ab
+4. Worker speichert Daten → Upsert in Datenbank mit Conflict Resolution
+
+**Migration Strategy**:
+- Phase 1: Neue Infrastruktur aufbauen (Queue, Worker)
+- Phase 2: Sync-Logik portieren (Auth, Fetch, Transform, Persist)
+- Phase 3: Frontend auf neue Architektur umstellen
+- Phase 4: Alte n8n-Komponenten entfernen
+- Phase 5: End-to-End Validierung mit Production-Daten
+
+## Dependencies
+
+- Job Queue System (z.B. BullMQ, Bee-Queue, oder vergleichbar)
+- In-Memory Data Store (z.B. Redis, KeyDB, oder vergleichbar) 
+- Microsoft Graph API Client Library (z.B. @azure/identity oder vergleichbar)
+- TypeScript Runtime für Worker-Prozess (z.B. tsx, ts-node, oder vergleichbar)

+## Implementation Notes
+
+### Task Execution Order
+
+**Sequential Tasks** (blocking):
+- T001 → T002-T004 → T005 (setup before queue)
+- T006-T007 → T008 (Redis before queue test)
+- T009 → T013 (worker before sync skeleton)
+- T041 → T042 (integration before test)
+- T043-T045 → T046 (implementation before E2E test)
+
+**Parallel Tasks** (can be done simultaneously):
+- T002, T003, T004 (env var updates)
+- T006, T007 (Redis + Queue files)
+- T010, T011, T012 (worker event handlers)
+- T015-T017, T018-T021 (auth independent from fetch)
+- T027-T029, T030-T031 (different parser types)
+- T047, T048 (file deletions)
+- T049-T054 (env var removals)
+- T056, T057, T058 (unit tests)
+
+### Common Pitfalls
+
+1. **Redis Connection**: Ensure `maxRetriesPerRequest: null` for BullMQ compatibility
+2. **Graph API**: Handle 429 rate limiting with exponential backoff
+3. **Pagination**: Always follow `@odata.nextLink` until undefined
+4. **Upsert**: Use correct constraint name `policy_settings_upsert_unique`
+5. **Worker Deployment**: Don't forget `concurrency: 1` for sequential processing
+
+### Testing Checkpoints
+
+- After T008: Redis + Queue working
+- After T014: Worker starts successfully
+- After T017: Token acquisition works
+- After T023: Graph API fetch with pagination works
+- After T035: Parser extracts >95% of settings
+- After T042: Full sync updates database
+- After T046: UI → Worker → DB flow complete
+- After T055: No n8n references remain
+- After T061: E2E test passes
+
+---
+
+**Task Status**: Ready for Implementation  
+**Next Action**: Start with Phase 1 (T001-T008) - Setup & Infrastructure

+# Technical Implementation Notes: Backend Architecture Pivot
+
+**Feature**: 005-backend-arch-pivot  
+**Created**: 2025-12-09  
+**Purpose**: Detailed implementation guidance for developers (not part of business specification)
+
+---
+
+## BullMQ Setup
+
+### Installation
+
+```bash
+npm install bullmq ioredis
+```
+
+### Redis Connection
+
+**File**: `lib/queue/redis.ts`
+
+```typescript
+import IORedis from 'ioredis';
+import { env } from '@/lib/env.mjs';
+
+export const redisConnection = new IORedis(env.REDIS_URL, {
+  maxRetriesPerRequest: null, // BullMQ requirement
+});
+```
+
+### Queue Definition
+
+**File**: `lib/queue/syncQueue.ts`
+
+```typescript
+import { Queue } from 'bullmq';
+import { redisConnection } from './redis';
+
+export const syncQueue = new Queue('intune-sync-queue', {
+  connection: redisConnection,
+});
+```
+
+---
+
+## Worker Implementation
+
+### Worker Entry Point
+
+**File**: `worker/index.ts`
+
+```typescript
+import { Worker } from 'bullmq';
+import { redisConnection } from '@/lib/queue/redis';
+import { syncPolicies } from './jobs/syncPolicies';
+
+const worker = new Worker(
+  'intune-sync-queue',
+  async (job) => {
+    console.log(`Processing job ${job.id} for tenant ${job.data.tenantId}`);
+    await syncPolicies(job.data.tenantId);
+  },
+  {
+    connection: redisConnection,
+    concurrency: 1, // Sequential processing
+  }
+);
+
+worker.on('completed', (job) => {
+  console.log(`Job ${job.id} completed`);
+});
+
+worker.on('failed', (job, err) => {
+  console.error(`Job ${job?.id} failed:`, err);
+});
+
+console.log('Worker started, listening on intune-sync-queue...');
+```
+
+### Package.json Script
+
+```json
+{
+  "scripts": {
+    "worker:start": "tsx watch worker/index.ts"
+  }
+}
+```
+
+---
+
+## Sync Logic Architecture
+
+### Main Function
+
+**File**: `worker/jobs/syncPolicies.ts`
+
+```typescript
+export async function syncPolicies(tenantId: string) {
+  // 1. Get Access Token
+  const token = await getGraphAccessToken();
+  
+  // 2. Fetch all policy types
+  const policies = await fetchAllPolicies(token);
+  
+  // 3. Parse & Flatten
+  const flattenedSettings = policies.flatMap(policy => 
+    parsePolicySettings(policy)
+  );
+  
+  // 4. Upsert to Database
+  await upsertPolicySettings(tenantId, flattenedSettings);
+}
+```
+
+### Authentication (Client Credentials)
+
+```typescript
+import { ClientSecretCredential } from '@azure/identity';
+
+async function getGraphAccessToken(): Promise<string> {
+  const credential = new ClientSecretCredential(
+    'common', // or specific tenant ID
+    env.AZURE_AD_CLIENT_ID,
+    env.AZURE_AD_CLIENT_SECRET
+  );
+  
+  const token = await credential.getToken('https://graph.microsoft.com/.default');
+  return token.token;
+}
+```
+
+### Pagination Handling
+
+```typescript
+async function fetchWithPagination<T>(url: string, token: string): Promise<T[]> {
+  let results: T[] = [];
+  let nextLink: string | undefined = url;
+  
+  while (nextLink) {
+    const response = await fetch(nextLink, {
+      headers: { Authorization: `Bearer ${token}` }
+    });
+    const data = await response.json();
+    
+    results = results.concat(data.value);
+    nextLink = data['@odata.nextLink'];
+  }
+  
+  return results;
+}
+```
+
+### Graph API Endpoints
+
+```typescript
+const GRAPH_ENDPOINTS = {
+  deviceConfigurations: 'https://graph.microsoft.com/v1.0/deviceManagement/deviceConfigurations',
+  compliancePolicies: 'https://graph.microsoft.com/v1.0/deviceManagement/deviceCompliancePolicies',
+  configurationPolicies: 'https://graph.microsoft.com/v1.0/deviceManagement/configurationPolicies',
+  intents: 'https://graph.microsoft.com/v1.0/deviceManagement/intents',
+};
+
+async function fetchAllPolicies(token: string) {
+  const [configs, compliance, configPolicies, intents] = await Promise.all([
+    fetchWithPagination(GRAPH_ENDPOINTS.deviceConfigurations, token),
+    fetchWithPagination(GRAPH_ENDPOINTS.compliancePolicies, token),
+    fetchWithPagination(GRAPH_ENDPOINTS.configurationPolicies, token),
+    fetchWithPagination(GRAPH_ENDPOINTS.intents, token),
+  ]);
+  
+  return [...configs, ...compliance, ...configPolicies, ...intents];
+}
+```
+
+---
+
+## Flattening Strategy
+
+### Settings Catalog (Most Complex)
+
+```typescript
+function parseSettingsCatalog(policy: any): FlattenedSetting[] {
+  if (!policy.settings) return [defaultEmptySetting(policy)];
+  
+  return policy.settings.flatMap(setting => {
+    const settingId = setting.settingInstance.settingDefinitionId;
+    const value = extractValue(setting.settingInstance);
+    
+    return {
+      settingName: humanizeSettingId(settingId),
+      settingValue: JSON.stringify(value),
+      settingValueType: typeof value,
+    };
+  });
+}
+
+function extractValue(settingInstance: any): any {
+  // Handle different value types
+  if (settingInstance.simpleSettingValue) {
+    return settingInstance.simpleSettingValue.value;
+  }
+  
+  if (settingInstance.choiceSettingValue) {
+    return settingInstance.choiceSettingValue.value;
+  }
+  
+  if (settingInstance.groupSettingCollectionValue) {
+    return settingInstance.groupSettingCollectionValue.children.map(
+      (child: any) => extractValue(child)
+    );
+  }
+  
+  return null;
+}
+```
+
+### OMA-URI
+
+```typescript
+function parseOmaUri(policy: any): FlattenedSetting[] {
+  if (!policy.omaSettings) return [defaultEmptySetting(policy)];
+  
+  return policy.omaSettings.map(oma => ({
+    settingName: oma.omaUri,
+    settingValue: oma.value,
+    settingValueType: oma.valueType || 'string',
+  }));
+}
+```
+
+### Humanizer
+
+```typescript
+function humanizeSettingId(id: string): string {
+  return id
+    .replace(/^device_vendor_msft_policy_config_/i, '')
+    .replace(/_/g, ' ')
+    .replace(/\b\w/g, c => c.toUpperCase());
+}
+```
+
+### Default Empty Setting
+
+```typescript
+function defaultEmptySetting(policy: any): FlattenedSetting {
+  return {
+    policyId: policy.id,
+    policyName: policy.displayName,
+    policyType: detectPolicyType(policy['@odata.type']),
+    settingName: '(No settings configured)',
+    settingValue: '',
+    settingValueType: 'empty',
+    path: '',
+  };
+}
+```
+
+### Policy Type Detection
+
+```typescript
+function detectPolicyType(odataType: string): string {
+  const typeMap: Record<string, string> = {
+    '#microsoft.graph.deviceManagementConfigurationPolicy': 'configurationPolicy',
+    '#microsoft.graph.windows10CustomConfiguration': 'deviceConfiguration',
+    '#microsoft.graph.windows10EndpointProtectionConfiguration': 'endpointSecurity',
+    '#microsoft.graph.deviceCompliancePolicy': 'compliancePolicy',
+    '#microsoft.graph.windowsUpdateForBusinessConfiguration': 'windowsUpdateForBusiness',
+    '#microsoft.graph.iosCustomConfiguration': 'deviceConfiguration',
+    '#microsoft.graph.androidManagedAppProtection': 'appConfiguration',
+  };
+  
+  return typeMap[odataType] || 'unknown';
+}
+```
+
+---
+
+## Database Upsert
+
+**File**: `worker/jobs/upsertPolicySettings.ts`
+
+```typescript
+import { db } from '@/lib/db';
+import { policySettings } from '@/lib/db/schema/policySettings';
+import { sql } from 'drizzle-orm';
+
+async function upsertPolicySettings(
+  tenantId: string,

+    lastSyncedAt: new Date(),
+  }));
+  
+  // Batch insert with conflict resolution
+  await db.insert(policySettings)
+    .values(records)
+    .onConflictDoUpdate({
+      target: [
+        policySettings.tenantId,

+      },
+    });
+}
+```
+
+---
+
+## Frontend Integration
+
+### Server Action Update
+
+**File**: `lib/actions/policySettings.ts`
+
+**Before** (n8n Webhook):
+```typescript
+const response = await fetch(env.N8N_SYNC_WEBHOOK_URL, {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({ tenantId }),
+});
+```
+
+**After** (BullMQ Job):
+```typescript
+import { syncQueue } from '@/lib/queue/syncQueue';
+
+export async function triggerPolicySync(tenantId: string) {
+  const job = await syncQueue.add('sync-tenant', { 
+    tenantId,

+      }
+      
+      // Exponential backoff for transient errors
+      if (attempt < maxRetries - 1) {
+        const delay = Math.pow(2, attempt) * 1000;

+# Specification Analysis Report: Feature 006 - Intune Reverse Engineering Strategy
+
+**Analyzed**: 2025-12-09  
+**Artifacts**: spec.md, tasks.md  
+**Constitution**: v1.0.0  
+**Note**: No plan.md exists (documentation feature - direct spec-to-tasks workflow)
+
+---
+
+## Executive Summary
+
+**Overall Status**: ✅ **READY FOR IMPLEMENTATION**
+
+This analysis examined Feature 006 against the project constitution, checked internal consistency between spec.md and tasks.md, and validated requirement coverage. The feature is a **documentation/guideline project** (not code implementation), which explains the absence of plan.md.
+
+**Key Findings**:
+- ✅ Zero CRITICAL issues
+- ⚠️ 3 MEDIUM issues (terminology clarification, missing plan.md rationale, scope boundary)
+- ℹ️ 4 LOW issues (style improvements, edge case examples)
+- ✅ 100% requirement-to-task coverage (all 8 FRs mapped)
+- ✅ Constitution alignment: This is a **process documentation feature** - constitution doesn't apply to non-code artifacts
+
+---
+
+## Findings
+
+| ID | Category | Severity | Location(s) | Summary | Recommendation |
+|----|----------|----------|-------------|---------|----------------|
+| C1 | Constitution | CRITICAL | N/A | Constitution principles (TypeScript, Server Actions, Drizzle) don't apply to documentation features | **RESOLVED**: Feature is process documentation, not code. Constitution correctly doesn't restrict documentation artifacts. |
+| A1 | Ambiguity | MEDIUM | spec.md:FR-004 | "Concrete examples" lacks quantitative threshold | Add minimum: "MUST provide at least 3 PowerShell-to-TypeScript mapping examples" |
+| A2 | Ambiguity | MEDIUM | spec.md:SC-003 | "Zero API surprises" is subjective without measurement method | Clarify: "verified by developer survey after guide usage" or "tracked via incident reports" |
+| I1 | Inconsistency | MEDIUM | spec.md vs tasks.md | Spec mentions "docs/architecture/intune-migration-guide.md" but doesn't explain why no plan.md | Add note in spec.md explaining this is documentation feature requiring direct implementation |
+| U1 | Underspecification | LOW | spec.md:FR-006 | "Extensive testing" undefined | Define: "at least 2 test tenants, 5 resource instances, validation against official docs" |
+| U2 | Underspecification | LOW | spec.md:Edge Case 4 | "[POWERSHELL QUIRK]" marker syntax not formalized | Specify format: "Use code comment: `// [POWERSHELL QUIRK]: <description>`" |
+| D1 | Duplication | LOW | tasks.md:T010 & T011 | Both tasks add "concrete examples" to same section - might overlap | Ensure T010 covers discovery process, T011 covers parameter implementation separately |
+| S1 | Scope | MEDIUM | spec.md + tasks.md | Boundary between "implementation guide" and "actual TypeScript code changes" unclear | Add note: Guide documents process; doesn't modify existing worker/jobs/ code |
+
+---
+
+## Coverage Analysis
+
+### Requirements Inventory
+
+| Requirement Key | Description | Has Task? | Task IDs | Coverage Status |
+|-----------------|-------------|-----------|----------|-----------------|
+| fr-001-step-by-step-process | Documentation MUST include step-by-step process | ✅ | T008 | Full coverage |
+| fr-002-powershell-location | Guide MUST specify PowerShell reference location | ✅ | T007, T002 | Full coverage |
+| fr-003-data-points-extract | Process MUST define data extraction points | ✅ | T009 | Full coverage |
+| fr-004-concrete-examples | Guide MUST provide concrete PS→TS examples | ✅ | T010, T011, T012, T013, T014 | Full coverage (5 tasks) |
+| fr-005-troubleshooting | Documentation MUST include troubleshooting section | ✅ | T015, T016, T017, T018 | Full coverage |
+| fr-006-fallback-process | Guide MUST define fallback for missing PS reference | ✅ | T024 | Full coverage |
+| fr-007-versioning-strategy | Process MUST include versioning strategy | ✅ | T003, T023 | Full coverage |
+| fr-008-replicate-vs-document | Guide MUST distinguish replicate vs document behaviors | ✅ | T027 | Full coverage |
+
+### User Story Coverage
+
+| Story | Priority | Has Tasks? | Task Count | Coverage Status |
+|-------|----------|------------|------------|-----------------|
+| US1 - Developer Implements Feature | P1 | ✅ | 7 (T008-T014) | Full coverage |
+| US2 - Developer Troubleshoots | P2 | ✅ | 4 (T015-T018) | Full coverage |
+| US3 - Onboarding New Team Member | P3 | ✅ | 4 (T019-T022) | Full coverage |
+
+### Edge Case Coverage
+
+| Edge Case | Description | Covered By | Status |
+|-----------|-------------|------------|--------|
+| EC1 | PowerShell reference updates | T025 | ✅ Covered |
+| EC2 | Deprecated features | T026 | ✅ Covered |
+| EC3 | Missing PowerShell equivalent | T024 (FR-006) | ✅ Covered |
+| EC4 | Undocumented PS behaviors/bugs | T027 (FR-008) | ✅ Covered |
+
+### Unmapped Tasks
+
+**None** - All 34 implementation tasks trace back to either:
+- Functional requirements (FR-001 to FR-008)
+- User stories (US1, US2, US3)
+- Edge cases (EC1-EC4)
+- Polish/validation activities (T028-T034)
+
+---
+
+## Constitution Alignment
+
+### Applicable Principles
+
+**Result**: ✅ **NO VIOLATIONS**
+
+**Rationale**: This feature produces **documentation artifacts** (markdown files), not code. The constitution explicitly governs:
+- Code architecture (Server Actions, TypeScript strict mode)
+- Database interactions (Drizzle ORM)
+- UI components (Shadcn UI)
+- Authentication (Azure AD)
+
+**Documentation features are exempt** from these technical constraints. The guide *references* TypeScript and PowerShell in examples, but doesn't implement new code that would trigger constitution requirements.
+
+### Non-Applicable Constitution Checks
+
+| Constitution Principle | Applies? | Reason |
+|------------------------|----------|--------|
+| I. Server-First Architecture | ❌ No | No Next.js code being written |
+| II. TypeScript Strict Mode | ❌ No | Documentation feature; code examples are illustrative |
+| III. Drizzle ORM Integration | ❌ No | No database schema changes |
+| IV. Shadcn UI Components | ❌ No | No UI components being created |
+| V. Azure AD Multi-Tenancy | ❌ No | No authentication changes |
+
+### Future Constitution Impact
+
+⚠️ **Note for Implementers**: When developers **use this guide** to implement sync jobs, those implementations MUST follow constitution principles:
+- TypeScript strict mode (Principle II)
+- Type-safe Graph API clients
+- This guide should reference constitution requirements in examples
+
+**Recommendation**: Add task to Phase 7 polish:
+- **T035**: Add constitution compliance notes to guide examples (remind developers to use TypeScript strict, type-safe API calls)
+
+---
+
+## Metrics
+
+- **Total Requirements**: 8 functional requirements (FR-001 to FR-008)
+- **Total User Stories**: 3 (US1, US2, US3)
+- **Total Tasks**: 34 implementation tasks + 10 validation checklist items
+- **Coverage %**: 100% (all requirements have >=1 task)
+- **Parallelizable Tasks**: 12 tasks marked [P]
+- **Ambiguity Count**: 2 (A1, A2)
+- **Duplication Count**: 1 (D1)
+- **Critical Issues**: 0
+- **Constitution Violations**: 0
+
+---
+
+## Detailed Analysis
+
+### Duplication Detection
+
+**Finding D1**: Tasks T010 and T011 both add "concrete examples" to intune-migration-guide.md
+- **Severity**: LOW
+- **Impact**: Potential overlap in content without clear boundaries
+- **Recommendation**: 
+  - T010 should focus on: Discovery workflow (how to find endpoint in .psm1 file)
+  - T011 should focus on: Parameter implementation (how to add discovered $expand to TypeScript)
+  - Update task descriptions to clarify distinction
+
+### Ambiguity Detection
+
+**Finding A1**: FR-004 requires "concrete examples" but doesn't specify minimum quantity
+- **Severity**: MEDIUM
+- **Location**: spec.md:L108
+- **Current Text**: "Guide MUST provide concrete examples mapping PowerShell patterns to TypeScript implementations"
+- **Issue**: "Concrete examples" is vague - could be 1 example or 10 examples
+- **Recommendation**: Update to: "Guide MUST provide at least 3 concrete examples mapping PowerShell patterns to TypeScript implementations (e.g., how PowerShell's `Invoke-MSGraphRequest` translates to `graphClient.api().get()`)"
+
+**Finding A2**: SC-003 uses subjective success criteria
+- **Severity**: MEDIUM
+- **Location**: spec.md:L155
+- **Current Text**: "Zero 'undocumented Graph API behavior' surprises after implementation"
+- **Issue**: "Surprises" is not measurable without defining measurement method
+- **Recommendation**: Update to: "Zero 'undocumented Graph API behavior' incidents after implementation (tracked via developer incident reports and code review feedback)"
+
+### Underspecification
+
+**Finding U1**: FR-006 mentions "extensive testing" without definition
+- **Severity**: LOW
+- **Location**: spec.md:L112
+- **Current Text**: "use official docs + extensive testing"
+- **Issue**: "Extensive testing" lacks concrete criteria
+- **Recommendation**: Define in guide: "Test against at least 2 different tenants, validate with 5+ resource instances, compare against official Microsoft Graph documentation"
+
+**Finding U2**: Edge Case 4 introduces `[POWERSHELL QUIRK]` marker without format specification
+- **Severity**: LOW
+- **Location**: spec.md:L85
+- **Current Text**: "Document them explicitly with `[POWERSHELL QUIRK]` markers"
+- **Issue**: Marker syntax not formalized (inline comment? separate doc section? code annotation?)
+- **Recommendation**: Specify format in FR-008 implementation (T027): "Use TypeScript comment format: `// [POWERSHELL QUIRK]: <description of non-standard behavior>`"
+
+### Inconsistency Detection
+
+**Finding I1**: Spec assumes tasks.md without explaining missing plan.md
+- **Severity**: MEDIUM
+- **Location**: spec.md (overall structure)
+- **Current State**: Spec jumps directly to tasks.md; no plan.md exists
+- **Issue**: Speckit framework typically requires spec.md → plan.md → tasks.md flow. This feature skips plan.md, but spec doesn't explain why
+- **Recommendation**: Add note to spec.md header:
+  ```markdown
+  **Implementation Approach**: This is a documentation feature (creating markdown guide). 
+  No plan.md required - tasks directly implement documentation sections from FR requirements.
+  ```
+
+**Finding S1**: Scope boundary between guide and codebase modifications unclear
+- **Severity**: MEDIUM
+- **Location**: spec.md + tasks.md (cross-cutting)
+- **Issue**: Tasks focus on writing guide content, but spec.md user stories mention "implement in TypeScript" which could be misinterpreted as modifying existing worker/jobs/ code
+- **Recommendation**: Add clarification to spec.md Introduction section:
+  ```markdown
+  **Scope**: This feature creates a *process guide* document. It does NOT modify existing 
+  TypeScript sync job implementations. Developers will use the guide for future implementations.
+  ```
+
+### Constitution Violations
+
+**Finding C1**: RESOLVED - No constitution violations
+- **Severity**: N/A
+- **Explanation**: Constitution governs code implementation patterns (Server Actions, TypeScript strict, Drizzle, Shadcn, Azure AD). This feature produces documentation, which is outside constitution scope.
+- **Future Note**: When developers use this guide to implement sync jobs, those implementations MUST follow constitution (see recommendation for T035 above)
+
+---
+
+## Recommendations Summary
+
+### High Priority (Before Implementation)
+
+1. **Clarify Scope Boundary** (Finding I1, S1)
+   - Add note to spec.md explaining why no plan.md exists
+   - Clarify that guide documents process, doesn't modify existing code
+
+2. **Quantify Ambiguous Requirements** (Finding A1, A2)
+   - FR-004: Specify "at least 3 concrete examples"
+   - SC-003: Define measurement method for "zero surprises"
+
+### Medium Priority (During Implementation)
+
+3. **Distinguish Overlapping Tasks** (Finding D1)
+   - Update T010/T011 descriptions to clarify scope difference
+
+4. **Define Underspecified Terms** (Finding U1, U2)
+   - FR-006: Define "extensive testing" criteria
+   - T027: Formalize `[POWERSHELL QUIRK]` marker syntax
+
+### Low Priority (Nice to Have)
+
+5. **Add Constitution Reference** (New suggestion)
+   - Create T035: Add constitution compliance notes to guide examples
+   - Remind developers using guide to follow TypeScript strict mode, type-safe patterns
+
+---
+
+## Next Actions
+
+### Recommended Path: Proceed with Implementation
+
+✅ **This specification is READY for implementation** with optional refinements:
+
+1. **Option A - Start Implementation Now**
+   - Current spec has 100% requirement coverage
+   - Zero critical issues
+   - Medium/Low issues can be addressed during implementation (Phase 7 polish)
+   - Begin with Phase 1 (T001-T003) immediately
+
+2. **Option B - Quick Refinement Pass (15 minutes)**
+   - Update spec.md header to explain missing plan.md (Finding I1)
+   - Update FR-004 to specify "at least 3 examples" (Finding A1)
+   - Update SC-003 to define measurement method (Finding A2)
+   - Then proceed to implementation
+
+3. **Option C - Comprehensive Refinement (30 minutes)**
+   - Address all recommendations above
+   - Create T035 for constitution compliance notes
+   - Re-run `/speckit.analyze` to validate fixes
+   - Then proceed to implementation
+
+### Implementation Strategy
+
+**Recommended MVP** (Phase 3 - User Story 1):
+- Delivers immediate value: developers can implement new features correctly
+- Achieves SC-001 (2-hour implementation time) and SC-002 (95% accuracy)
+- Can ship and iterate on remaining phases
+
+**Parallel Execution**:
+- After T004 (foundation), run T008, T009, T015, T019 in parallel
+- After Phase 3-5 complete, run T023-T027 (edge cases) in parallel
+- Polish phase (T028-T034) can have multiple parallel streams
+
+---
+
+## Validation Notes
+
+**Analysis Methodology**:
+1. Loaded spec.md requirements inventory (8 FRs, 3 user stories, 6 success criteria, 4 edge cases)
+2. Loaded tasks.md task inventory (34 implementation tasks, 7 phases)
+3. Mapped each requirement to covering tasks - achieved 100% coverage
+4. Checked constitution alignment - confirmed documentation exemption
+5. Identified ambiguities using keyword search (fast, scalable, secure, intuitive, robust, TODO, TKTK) - found 2 instances
+6. Identified duplications via semantic similarity - found 1 instance
+7. Identified inconsistencies via cross-artifact comparison - found 2 instances
+
+**Confidence Level**: HIGH
+- All mandatory sections present in spec.md
+- All requirements traced to tasks
+- Constitution correctly doesn't apply to documentation features
+- Findings are actionable with specific recommendations
+
+---
+
+## Appendix: Constitution Compliance for Future Implementations
+
+While this **documentation feature** is constitution-exempt, **implementations using this guide** MUST comply:
+
+### When Implementing Sync Jobs (Using This Guide)
+
+✅ **MUST Follow**:
+- TypeScript strict mode (Constitution II)
+- Type-safe Graph API client usage
+- Server-side execution patterns
+- Error handling and logging standards
+
+❌ **MUST AVOID**:
+- Client-side Graph API calls
+- `any` types in TypeScript
+- Inconsistent error handling
+
+### Recommendation for Guide Content
+
+Add section to intune-migration-guide.md (during T032 review):
+```markdown
+## Constitution Compliance
+
+When implementing sync jobs using this guide:
+- All TypeScript MUST use strict mode (`strict: true` in tsconfig.json)
+- Graph API calls MUST be type-safe (define interfaces for all API responses)
+- Sync jobs run server-side (worker process) - client-side fetching prohibited
+- Follow project's error handling patterns (see worker/utils/errorHandler.ts)
+```
+
+This ensures developers using the guide produce constitution-compliant implementations.
+

+
+## Feature Readiness
+
+- [✓] All functional requirements have clear acceptance criteria
+- [✓] User scenarios cover primary flows
+- [✓] Feature meets measurable outcomes defined in Success Criteria
+- [✓] No implementation details leak into specification
+
+## Validation Summary
+
+**Status**: ✅ PASSED
+
+All checklist items have been validated successfully:
+
+### Content Quality Analysis
+- ✅ The spec focuses on WHAT developers need (reverse engineering process) without specifying HOW to build the documentation system
+- ✅ User stories describe developer workflows and business outcomes (reduced onboarding time, fewer bugs)
+- ✅ Language is accessible - explains concepts like "PowerShell reference module" and "API endpoint pattern"
+- ✅ All 3 mandatory sections present: User Scenarios & Testing, Requirements, Success Criteria
+
+### Requirement Completeness Analysis
+- ✅ Zero [NEEDS CLARIFICATION] markers in the spec
+- ✅ All 8 functional requirements (FR-001 to FR-008) are testable: can verify if documentation includes each specified element
+- ✅ All 6 success criteria (SC-001 to SC-006) have numeric targets: 2 hours, 95% accuracy, 50% reduction, etc.
+- ✅ Success criteria avoid implementation details (e.g., "developer can implement" not "TypeScript code compiles")
+- ✅ Each user story includes 2-3 acceptance scenarios with Given/When/Then format
+- ✅ Edge cases section covers 4 scenarios: PowerShell updates, deprecated features, missing references, quirky behaviors
+- ✅ Scope is bounded: focuses on reverse engineering strategy, not the actual implementation of sync jobs
+- ✅ Dependencies documented: requires `IntuneManagement-master/` directory as reference source (FR-002)
+
+### Feature Readiness Analysis
+- ✅ All functional requirements map to user story acceptance scenarios:
+  - FR-001 (step-by-step process) → User Story 1 Scenario 1
+  - FR-003 (data points to extract) → User Story 1 Scenario 2
+  - FR-005 (troubleshooting section) → User Story 2 Scenarios
+  - FR-007 (versioning strategy) → Edge Case 1
+- ✅ User stories cover complete workflow: implementation (P1) → troubleshooting (P2) → knowledge transfer (P3)
+- ✅ Success criteria align with user outcomes: SC-001 (time savings) validates User Story 1, SC-004 (onboarding) validates User Story 3
+- ✅ No implementation leakage detected (e.g., doesn't specify markdown vs wiki vs code comments for documentation format)
+
+## Notes
+
+This specification is ready for `/speckit.plan` or implementation. No further clarifications or revisions needed.
+
+**Next Steps**:
+1. ✅ Implementation complete - all tasks executed
+2. ✅ All 8 functional requirements validated in guide
+3. ✅ Guide published at `docs/architecture/intune-migration-guide.md`

+# Feature Specification: Technical Standard - Intune Reverse Engineering Strategy
+
+**Feature Branch**: `006-intune-reverse-engineering-guide`  
+**Created**: 2025-12-09  
+**Status**: Draft  
+**Input**: User description: "Technical Standard - Intune Reverse Engineering Strategy"
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Developer Implements New Intune Feature (Priority: P1)
+
+A backend developer receives a request to add support for a new Intune resource type (e.g., "App Protection Policies"). They need a clear process to ensure the implementation matches Microsoft's actual Graph API behavior and includes all necessary parameters, filters, and data transformations.
+
+**Why this priority**: This is the core workflow that enables all future Intune feature additions. Without this guideline, developers will make inconsistent API calls, miss critical parameters, and create technical debt.
+
+**Independent Test**: Can be fully tested by having a developer follow the guide to implement one new resource type (e.g., Compliance Policies) and verify that the TypeScript implementation matches the PowerShell reference behavior exactly (same endpoints, same filters, same data shape).
+
+**Acceptance Scenarios**:
+
+1. **Given** a feature request for "Windows Update Rings", **When** developer follows the guide to analyze `IntuneManagement/Modules/WindowsUpdateRings.psm1`, **Then** they identify the exact Graph endpoint (`/deviceManagement/windowsUpdateForBusinessConfigurations`), required filters (`$filter=`), and property cleanup logic before writing any TypeScript code.
+
+2. **Given** a new Settings Catalog policy type needs to be synced, **When** developer references the PowerShell code for Settings Catalog, **Then** they discover the `$expand=settings` parameter is required (not documented in Graph API docs) and implement it in TypeScript.
+
+3. **Given** an AI agent is tasked with implementing a new sync job, **When** the agent reads this guide, **Then** it knows to search for the corresponding `.psm1` file first, extract API patterns, and document any undocumented behaviors before generating TypeScript code.
+
+---
+
+### User Story 2 - Developer Troubleshoots API Discrepancy (Priority: P2)
+
+A developer notices that the TypeScript implementation returns different data than the PowerShell tool for the same Intune resource. They need a systematic way to identify what's missing in the TypeScript implementation.
+
+**Why this priority**: This handles maintenance and bug fixes for existing features. It's less critical than the initial implementation process but essential for long-term reliability.
+
+**Independent Test**: Can be tested by intentionally creating a "broken" implementation (missing an `$expand` parameter), then using the guide to trace back to the PowerShell reference and identify the fix.
+
+**Acceptance Scenarios**:
+
+1. **Given** TypeScript sync returns incomplete data for Configuration Policies, **When** developer compares against the PowerShell reference module, **Then** they discover a missing `$expand=assignments` parameter and add it to the TypeScript implementation.
+
+2. **Given** a sync job fails with "400 Bad Request", **When** developer checks the PowerShell reference for that resource type, **Then** they find undocumented query parameter requirements (e.g., API version must be `beta` not `v1.0`).
+
+---
+
+### User Story 3 - Onboarding New Team Member (Priority: P3)
+
+A new developer joins the project and needs to understand why the codebase uses specific Graph API patterns that seem to differ from official Microsoft documentation.
+
+**Why this priority**: Good documentation reduces onboarding time and prevents future developers from "fixing" intentional design decisions that match the PowerShell reference.
+
+**Independent Test**: A new developer can read the guide and understand the rationale for existing implementation choices without needing to ask the original author.
+
+**Acceptance Scenarios**:
+
+1. **Given** a new developer sees code that deletes certain properties before saving (e.g., `delete policy.createdDateTime`), **When** they read the migration guide, **Then** they understand this matches the PowerShell cleanup logic and shouldn't be "refactored away".
+
+2. **Given** a developer wonders why some endpoints use beta API, **When** they consult the guide, **Then** they learn to check the PowerShell reference first before attempting to "upgrade" to v1.0.
+
+---
+
+### Edge Cases
+
+- What happens when the PowerShell reference module is updated with breaking changes? (Guide should include a versioning strategy: document which PowerShell commit/version was used as reference)
+- How does the system handle Intune features that exist in PowerShell but are deprecated by Microsoft? (Mark as "reference only, do not implement new features")
+- What if a new Intune feature has no PowerShell equivalent yet? (Define a fallback process: use official Graph docs + extensive testing, document assumptions)
+- How do we handle undocumented PowerShell behaviors that seem like bugs? (Document them explicitly with `[POWERSHELL QUIRK]` markers and decide case-by-case whether to replicate)
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: Documentation MUST include a step-by-step process for analyzing PowerShell reference code before implementing TypeScript equivalents
+- **FR-002**: Guide MUST specify the location of the PowerShell reference source (`IntuneManagement-master/` directory in the repo)
+- **FR-003**: Process MUST define which data points to extract from PowerShell code: exact API endpoints, query parameters (`$filter`, `$expand`, `$select`), API version (beta vs v1.0), property cleanup/transformation logic
+- **FR-004**: Guide MUST provide concrete examples mapping PowerShell patterns to TypeScript implementations (e.g., how PowerShell's `Invoke-MSGraphRequest` translates to `graphClient.api().get()`)
+- **FR-005**: Documentation MUST include a troubleshooting section for when TypeScript behavior doesn't match PowerShell reference
+- **FR-006**: Guide MUST define a fallback process for Intune features that have no PowerShell reference (use official docs + extensive testing)
+- **FR-007**: Process MUST include versioning strategy: document which PowerShell commit/version is used as reference for each implemented feature
+- **FR-008**: Guide MUST distinguish between "must replicate" behaviors (intentional API patterns) and "document but don't replicate" behaviors (PowerShell-specific quirks)
+
+### Key Entities
+
+- **PowerShell Reference Module**: A `.psm1` file in `IntuneManagement-master/Modules/` that implements sync logic for a specific Intune resource type (e.g., `ConfigurationPolicies.psm1`, `Applications.psm1`)
+- **API Endpoint Pattern**: The exact Microsoft Graph URL path, API version, and query parameters required to fetch an Intune resource
+- **Data Transformation Rule**: Logic that modifies API response data before storage (e.g., property deletion, type conversions, flattening nested structures)
+- **Implementation Mapping**: The relationship between a PowerShell function (e.g., `Get-IntuneConfigurationPolicies`) and its TypeScript equivalent (e.g., `worker/jobs/syncConfigurationPolicies.ts`)
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: A developer can implement a new Intune resource type sync job in under 2 hours by following the guide (compared to 8+ hours of trial-and-error without it)
+- **SC-002**: 95% of newly implemented sync jobs match PowerShell reference behavior on first attempt (verified by comparing API calls and returned data)
+- **SC-003**: Zero "undocumented Graph API behavior" surprises after implementation (all quirks are discovered during PowerShell analysis phase)
+- **SC-004**: New team members can understand existing API implementation choices within 30 minutes of reading the guide (verified by onboarding feedback)
+- **SC-005**: Code review time for new Intune features reduced by 50% (reviewers can verify against PowerShell reference instead of testing manually)
+- **SC-006**: Technical debt reduced: zero instances of "why is this endpoint using beta API?" questions after guide adoption (rationale is documented in the guide or feature spec)

+**Explanation**:
+- **Setup & Foundation** must complete first (T001-T007)
+- **US1, US2, US3** are independent after foundation - can be written in parallel
+- **Edge Cases** depend on having core sections complete (to add edge case notes in context)
+- **Polish** comes last to add examples and review completeness
+
+### Task-Level Dependencies
+
+**Critical Path** (must complete in order):
+1. T001 (create directory) → T004 (create main guide file)
+2. T004 (create file) → All section-writing tasks (T008-T027)
+3. All section tasks complete → T028-T034 (polish tasks)
+
+**Parallel Opportunities**:
+- T002, T003 can run parallel with T001
+- T008, T009, T015, T019, T023-T027 can run in parallel after T004
+- T029, T030, T033 can run in parallel during polish phase

+
+## Parallel Execution Examples
+
+### Phase 3 - User Story 1 (After T004 completes)
+Run these tasks simultaneously:
+```bash
+# Terminal 1: Implementation process guide
+# Task T008 - Write step-by-step process
+
+# Terminal 2: Data extraction checklist
+# Task T009 - Create extraction checklist
+
+# Both tasks write to different sections of the same file
+```
+
+### Phase 6 - Edge Cases (After Phase 3-5 complete)
+Run all edge case sections in parallel:
+```bash
+# These are all independent sections that can be written simultaneously
+# T023: Versioning strategy
+# T024: Fallback process
+# T025: PowerShell updates
+# T026: Deprecated features
+# T027: Quirks vs patterns
+```
+
+### Phase 7 - Polish (Final phase)
+Run code example tasks in parallel:
+```bash
+# Terminal 1: T029 - Add PowerShell code snippets
+# Terminal 2: T030 - Add TypeScript examples
+# Terminal 3: T033 - Add links to existing implementations
+```
+

+
+### MVP Scope (Ship This First)
+**Phase 3: User Story 1 - Implementation Process Guide**
+- This is the core value: enables developers to implement new features correctly
+- Includes: Step-by-step process (T008), data extraction checklist (T009), concrete examples (T010-T014)
+- **Delivers SC-001**: Reduces implementation time from 8 hours to 2 hours
+- **Delivers SC-002**: 95% first-attempt accuracy by following the process
+
+### Incremental Delivery
+1. **MVP** (Phase 3): Ship US1 implementation guide → developers can start using it immediately
+2. **V1.1** (Phase 4): Add US2 troubleshooting → helps with existing bugs
+3. **V1.2** (Phase 5): Add US3 onboarding → reduces team onboarding time
+4. **V2.0** (Phase 6-7): Add edge cases and polish → complete reference guide
+
+### Success Metrics (Track These)
+- **SC-001**: Measure implementation time before/after guide (target: 2 hours vs 8 hours)
+- **SC-002**: Track first-attempt accuracy rate (target: 95%)
+- **SC-003**: Count "API surprises" incidents before/after (target: zero after)
+- **SC-004**: Measure onboarding time for new developers (target: 30 minutes)
+- **SC-005**: Track code review time reduction (target: 50% reduction)
+- **SC-006**: Count "why beta API?" questions in code reviews (target: zero)
+
+---
+
+## Validation Checklist
+
+Before marking tasks complete, verify:
+
+- [ ] All 8 functional requirements (FR-001 to FR-008) are addressed in the guide
+- [ ] Each user story has concrete, actionable examples (not just theory)
+- [ ] Guide includes at least 3 real PowerShell → TypeScript examples
+- [ ] Troubleshooting section has step-by-step diagnostic process
+- [ ] Versioning strategy explains how to document PowerShell reference version
+- [ ] Fallback process defined for features without PowerShell reference
+- [ ] Edge cases from spec.md are all documented
+- [ ] Code snippets are executable and tested
+- [ ] Links to existing implementations (worker/jobs/) are included
+- [ ] Guide is independently usable (doesn't require asking the author for clarification)
+
+---
+
+## Notes
+
+**About This Feature**: This is a documentation/guideline feature, not a code implementation feature. The "output" is a comprehensive markdown guide that developers (human and AI) will reference when implementing Intune sync jobs.
+
+**Success Definition**: The guide is successful when a developer can implement a new Intune resource type sync job by following the guide alone, without needing to ask questions or make multiple attempts.
+
+**Maintenance**: When PowerShell reference is updated, review the guide and update version references. Add new examples as new sync jobs are implemented.

+Worker container and Dokploy settings
+====================================
+
+Build context
+-------------
+- **Build path: `/` (repo root)** — NOT `worker/`!
+- **Dockerfile path: `worker/Dockerfile`**
+
+**IMPORTANT**: Dokploy must build from the repo root (`/`) so the Dockerfile can access `package.json`, `lib/`, and other files. If build path is set to `worker/`, the build will fail with "package.json: not found".
+
+Two-stage build (recommended)
+-----------------------------
+- This repository includes a two-stage Dockerfile that compiles TypeScript in a builder stage and produces a smaller runtime image.
+- The builder stage runs `npx tsc -p tsconfig.json --outDir dist` and the runtime stage will run the compiled `dist/worker/index.js` if present. If compilation is not performed, the container falls back to running `npx tsx ./worker/index.ts`.
+
+Recommended Dokploy settings
+----------------------------
+- Provider: `Gitea`
+- Repository: `ahmido/tenantpilot` (or your repo)
+- Branch: `development`
+- **Build path: `/`** (repo root)
+- **Dockerfile path: `worker/Dockerfile`**
+- Watch paths: `worker/**`, `lib/**`, `package.json`, `package-lock.json`
+
+Notes
+-----
+- The Dockerfile attempts to run compiled JS first; if no compiled output is present the runtime falls back to `tsx`.
+- If Dokploy requires a separate webhook per app, use the worker webhook URL provided in this repo's docs/workflow.
+
+Notes on environment
+--------------------
+- Ensure Dokploy provides `REDIS_URL` in the environment for the worker container.
+- Provide Azure AD secrets in Dokploy environment vars: `AZURE_AD_TENANT_ID`, `AZURE_AD_CLIENT_ID`, `AZURE_AD_CLIENT_SECRET`.
+Worker container and Dokploy settings
+====================================
+
+Build context
+-------------
+- Build path: `worker/` (Dokploy should use this path so the worker Dockerfile is found)
+- Dockerfile: `worker/Dockerfile`
+
+Recommended Dokploy settings
+----------------------------
+- Provider: `Gitea`
+- Repository: `ahmido/tenantpilot` (or your repo)
+- Branch: `development`
+- Build path: `worker/`
+- Watch paths: `worker/**`, `lib/**`, `package.json`, `package-lock.json`
+
+Notes
+-----
+- The `Dockerfile` runs `npm ci` and then `npm run worker:start`, which uses `tsx` to execute `worker/index.ts` directly.
+- If you prefer a smaller production image, consider adding a build step to compile TypeScript to JS and run the compiled output with `node`.
