+## Architecture Overview
+
+**LiveDash-Node** is a real-time analytics dashboard for monitoring user sessions with AI-powered analysis and processing pipeline.
+
+### Tech Stack
+
+- **Frontend:** Next.js 15 + React 19 + TailwindCSS 4
+- **Backend:** Next.js API Routes + Custom Node.js server
+- **Database:** PostgreSQL with Prisma ORM
+- **Authentication:** NextAuth.js
+- **AI Processing:** OpenAI API integration
+- **Visualization:** D3.js, React Leaflet, Recharts
+- **Scheduling:** Node-cron for background processing
+
+### Key Architecture Components
+
+**1. Multi-Stage Processing Pipeline**
+The system processes user sessions through distinct stages tracked in `SessionProcessingStatus`:
+
+- `CSV_IMPORT` - Import raw CSV data into `SessionImport`
+- `TRANSCRIPT_FETCH` - Fetch transcript content from URLs
+- `SESSION_CREATION` - Create normalized `Session` and `Message` records
+- `AI_ANALYSIS` - AI processing for sentiment, categorization, summaries
+- `QUESTION_EXTRACTION` - Extract questions from conversations
+
+**2. Database Architecture**
+
+- **Multi-tenant design** with `Company` as root entity
+- **Dual storage pattern**: Raw CSV data in `SessionImport`, processed data in `Session`
+- **1-to-1 relationship** between `SessionImport` and `Session` via `importId`
+- **Message parsing** into individual `Message` records with order tracking
+- **AI cost tracking** via `AIProcessingRequest` with detailed token usage
+- **Flexible AI model management** through `AIModel`, `AIModelPricing`, and `CompanyAIModel`
+
+**3. Custom Server Architecture**
+
+- `server.ts` - Custom Next.js server with configurable scheduler initialization
+- Three main schedulers: CSV import, import processing, and session processing
+- Environment-based configuration via `lib/env.ts`
+
+**4. Key Processing Libraries**
+
+- `lib/scheduler.ts` - CSV import scheduling
+- `lib/importProcessor.ts` - Raw data to Session conversion
+- `lib/processingScheduler.ts` - AI analysis pipeline
+- `lib/transcriptFetcher.ts` - External transcript fetching
+- `lib/transcriptParser.ts` - Message parsing from transcripts
+- `lib/batchProcessor.ts` - OpenAI Batch API integration for cost-efficient processing
+- `lib/batchScheduler.ts` - Automated batch job lifecycle management
+- `lib/rateLimiter.ts` - In-memory rate limiting utility for API endpoints
+
+### Development Environment
+
+**Environment Configuration:**
+Environment variables are managed through `lib/env.ts` with .env.local file support:
+
+- Database: PostgreSQL via `DATABASE_URL` and `DATABASE_URL_DIRECT`
+- Authentication: `NEXTAUTH_SECRET`, `NEXTAUTH_URL`
+- AI Processing: `OPENAI_API_KEY`
+- Schedulers: `SCHEDULER_ENABLED`, various interval configurations
+
+**Key Files to Understand:**
+
+- `prisma/schema.prisma` - Complete database schema with enums and relationships
+- `server.ts` - Custom server entry point
+- `lib/env.ts` - Environment variable management and validation
+- `app/` - Next.js App Router structure
+
+**Testing:**
+
+- Uses Vitest for unit testing
+- Playwright for E2E testing
+- Test files in `tests/` directory
+
+### Important Notes
+
+**Scheduler System:**
+
+- Schedulers are optional and controlled by `SCHEDULER_ENABLED` environment variable
+- Use `pnpm dev:next-only` to run without schedulers for pure frontend development
+- Four separate schedulers handle different pipeline stages:
+  - CSV Import Scheduler (`lib/scheduler.ts`)
+  - Import Processing Scheduler (`lib/importProcessor.ts`)
+  - Session Processing Scheduler (`lib/processingScheduler.ts`)
+  - Batch Processing Scheduler (`lib/batchScheduler.ts`) - Manages OpenAI Batch API lifecycle
+
+**Database Migrations:**
+
+- Always run `pnpm prisma:generate` after schema changes
+- Use `pnpm prisma:migrate` for production-ready migrations
+- Use `pnpm prisma:push` for development schema changes
+- Database uses PostgreSQL with Prisma's driver adapter for connection pooling
+
+**AI Processing:**
+
+- All AI requests are tracked for cost analysis
+- Support for multiple AI models per company
+- Time-based pricing management for accurate cost calculation
+- Processing stages can be retried on failure with retry count tracking
+- **Batch API Integration**: 50% cost reduction using OpenAI Batch API
+  - Automatic batching of AI requests every 5 minutes
+  - Batch status checking every 2 minutes
+  - Result processing every minute
+  - Failed request retry with individual API calls
+
+**Code Quality Standards:**
+
+- Run `pnpm lint` and `pnpm format:check` before committing
+- TypeScript with ES modules (type: "module" in package.json)
+- React 19 with Next.js 15 App Router
+- TailwindCSS 4 for styling
+
+**Security Features:**
+
+- **Comprehensive CSRF Protection**: Multi-layer CSRF protection with automatic token management
+  - Middleware-level protection for all state-changing endpoints
+  - tRPC integration with CSRF-protected procedures
+  - Client-side hooks and components for seamless integration
+  - HTTP-only cookies with SameSite protection
+- **Enhanced Content Security Policy (CSP)**:
+  - Nonce-based script execution for maximum XSS protection
+  - Environment-specific policies (strict production, permissive development)
+  - Real-time violation reporting and bypass detection
+  - Automated policy optimization recommendations
+- **Security Monitoring & Audit System**:
+  - Real-time threat detection and alerting
+  - Comprehensive security audit logging with retention management
+  - Geographic anomaly detection and IP threat analysis
+  - Security scoring and automated incident response
+- **Advanced Rate Limiting**: In-memory rate limiting system
+  - Authentication endpoints: Login (5/15min), Registration (3/hour), Password Reset (5/15min)
+  - CSP reporting: 10 reports per minute per IP
+  - Admin endpoints: Configurable thresholds
+- **Input Validation & Security Headers**:
+  - Comprehensive Zod schemas for all user inputs with XSS/injection prevention
+  - HTTP security headers (HSTS, X-Frame-Options, X-Content-Type-Options, Permissions Policy)
+  - Strong password requirements and email validation
+- **Session Security**:
+  - JWT tokens with 24-hour expiration and secure cookie settings
+  - HttpOnly, Secure, SameSite cookies with proper CSP integration
+  - Company isolation and multi-tenant security
+
+**Code Quality & Linting:**
+
+- **Biome Integration**: Primary linting and formatting tool
+  - Pre-commit hooks enforce code quality standards
+  - Some security-critical patterns require `biome-ignore` comments
+  - Non-null assertions (`!`) used intentionally in authenticated contexts require ignore comments
+  - Complex functions may need refactoring to meet complexity thresholds (max 15)
+  - Performance classes use static-only patterns which may trigger warnings
+- **TypeScript Strict Mode**: Comprehensive type checking
+  - Avoid `any` types where possible; use proper type definitions
+  - Optional chaining vs non-null assertions: choose based on security context
+  - In authenticated API handlers, non-null assertions are often safer than optional chaining
+- **Security vs Linting Balance**:
+  - Security takes precedence over linting rules when they conflict
+  - Document security-critical choices with detailed comments
+  - Use `// biome-ignore` with explanations for intentional rule violations

+# 🚨 Database Connection Issues - Fixes Applied
+
+## Issues Identified
+
+From your logs:
+
+```
+Can't reach database server at `ep-tiny-math-a2zsshve-pooler.eu-central-1.aws.neon.tech:5432`
+[NODE-CRON] [WARN] missed execution! Possible blocking IO or high CPU
+```
+
+## Root Causes
+
+1.  **Multiple PrismaClient instances** across schedulers
+2.  **No connection retry logic** for temporary failures
+3.  **No connection pooling optimization** for Neon
+4.  **Aggressive scheduler intervals** overwhelming database
+
+## Fixes Applied ✅
+
+### 1. Connection Retry Logic (`lib/database-retry.ts`)
+
+- **Automatic retry** for connection errors
+- **Exponential backoff** (1s → 2s → 4s → 10s max)
+- **Smart error detection** (only retry connection issues)
+- **Configurable retry attempts** (default: 3 retries)
+
+### 2. Enhanced Schedulers
+
+- **Import Processor**: Added retry wrapper around main processing
+- **Session Processor**: Added retry wrapper around AI processing
+- **Graceful degradation** when database is temporarily unavailable
+
+### 3. Singleton Pattern Enforced
+
+- **All schedulers now use** `import { prisma } from "./prisma.js"`
+- **No more separate** `new PrismaClient()` instances
+- **Shared connection pool** across all operations
+
+### 4. Neon-Specific Optimizations
+
+- **Connection limit guidance**: 15 connections (below Neon's 20 limit)
+- **Extended timeouts**: 30s for cold start handling
+- **SSL mode requirements**: `sslmode=require` for Neon
+- **Application naming**: For better monitoring
+
+## Immediate Actions Needed
+
+### 1. Update Environment Variables
+
+```bash
+# Add to .env.local
+USE_ENHANCED_POOLING=true
+DATABASE_CONNECTION_LIMIT=15
+DATABASE_POOL_TIMEOUT=30
+
+# Update your DATABASE_URL to include:
+DATABASE_URL="postgresql://user:pass@ep-tiny-math-a2zsshve-pooler.eu-central-1.aws.neon.tech:5432/db?sslmode=require&connection_limit=15&pool_timeout=30"
+```
+

+
+## 🏛️ Architectural Decisions & Rationale
+
+### Service Technology Choices
+
+-   **Dashboard Service**: Next.js + tRPC (existing, proven stack)
+-   **Data Ingestion Service**: Golang (high-performance CSV processing, concurrency)
+-   **AI Processing Service**: Node.js/Python (existing AI integrations, async processing)
+-   **Message Queue**: Redis + BullMQ (Node.js ecosystem compatibility)
+-   **Database**: PostgreSQL (existing, excellent for multi-tenancy)
+
+### Why Golang for Data Ingestion?
+
+-   **Performance**: 10-100x faster CSV processing than Node.js
+-   **Concurrency**: Native goroutines for parallel transcript fetching
+-   **Memory Efficiency**: Lower memory footprint for large CSV files
+-   **Deployment**: Single binary deployment, excellent for containers
+-   **Team Growth**: Easy to hire Golang developers for data processing
+
+### Migration Strategy
+
+1.  **Keep existing working system** while building new services
+2.  **Feature flagging** to gradually migrate companies to new processing
+3.  **Dual-write approach** during transition period
+4.  **Zero-downtime migration** with careful rollback plans
+
+### Compliance Benefits
+
+-   **Data Isolation**: Each service has limited database access
+-   **Audit Trail**: All inter-service communication logged
+-   **Data Retention**: Automated per-company data lifecycle
+-   **Security Boundaries**: DMZ for ingestion, private network for processing
+
+## Notes
+
+-   **CRITICAL**: Architectural refactoring must be priority #1 for scalability
+-   **Platform Management**: Notso AI needs self-service customer onboarding
+-   **Compliance First**: GDPR/ISO 27001 requirements drive service boundaries
+-   **Performance**: Current monolith blocks on CSV/AI processing
+-   **Technology Evolution**: Golang for data processing, tRPC for type safety

-# Application Improvement TODOs
-
-This file lists general areas for improvement and tasks that are broader in scope or don't map to a single specific file.
-
-## General Enhancements & Features
-
--   [ ] **Real-time Updates:** Implement real-time updates for the dashboard and session list (e.g., using WebSockets or Server-Sent Events).
--   [ ] **Data Export:** Provide functionality for users (especially admins) to export session data (e.g., to CSV).
--   [ ] **Customizable Dashboard:** Allow users to customize their dashboard view, choosing which metrics or charts are most important to them.
--   [ ] **Resolve `GeographicMap.tsx` and `ResponseTimeDistribution.tsx` data simulation:** The `docs/dashboard-components.md` mentions these use simulated data. Investigate integrating real data sources.
-
-## Robustness and Maintainability
-
--   [ ] **Comprehensive Testing:**
-    -   [ ] Implement unit tests (e.g., for utility functions, API logic).
-    -   [ ] Implement integration tests (e.g., for API endpoints with the database).
-    -   [ ] Implement end-to-end tests (e.g., for user flows using Playwright or Cypress).
--   [ ] **Error Monitoring and Logging:** Integrate a robust error monitoring service (like Sentry) and enhance server-side logging.
--   [ ] **Accessibility (a11y):** Review and improve the application's accessibility according to WCAG guidelines (keyboard navigation, screen reader compatibility, color contrast).
-
-## Security Enhancements
-
--   [x] **Password Reset Functionality:** Implement a secure password reset mechanism. (Related: `app/forgot-password/page.tsx`, `app/reset-password/page.tsx`, `pages/api/forgot-password.ts`, `pages/api/reset-password.ts` - ensure these are robust and secure if already implemented).
--   [ ] **Two-Factor Authentication (2FA):** Consider adding 2FA, especially for admin accounts.
--   [ ] **Input Validation and Sanitization:** Rigorously review and ensure all user inputs (API request bodies, query parameters) are validated and sanitized.
-
-## Code Quality and Development Practices
-
--   [ ] **Code Reviews:** Enforce code reviews for all changes.
--   [ ] **Environment Configuration:** Ensure secure and effective management of environment-specific configurations.
--   [ ] **Dependency Review:** Periodically review dependencies for vulnerabilities or updates.
--   [ ] **Documentation:**
-    -   Ensure `docs/dashboard-components.md` is up-to-date with actual component implementations.
-    -   Verify that "Dashboard Enhancements" (Improved Layout, Visual Hierarchies, Color Coding) are consistently applied.
-
-## Component Specific
-
--   [ ] **`pages/api/dashboard/users.ts`:** Implement robust emailing of temporary passwords.
--   [x] **`app/dashboard/sessions/page.tsx`:** Implement pagination, advanced filtering, and sorting.
-
-## File Cleanup
-
--   [x] Review and remove `.bak` and `.new` files once changes are integrated (e.g., `GeographicMap.tsx.bak`, `SessionDetails.tsx.bak`, `SessionDetails.tsx.new`).

+/*
+COMPARISON: Before vs After Refactoring
+
+BEFORE (Original Implementation):
+- ❌ Manual session authentication with repetitive code
+- ❌ Inconsistent error responses: { error: "...", details: "..." }
+- ❌ No input validation - accepts any query parameters
+- ❌ No rate limiting protection
+- ❌ No audit logging for security monitoring
+- ❌ Manual pagination parameter extraction
+- ❌ Inconsistent response format: { sessions, totalSessions }
+- ❌ Basic error logging without context
+- ❌ No company access validation
+- ❌ Performance issue: sequential database queries
+
+AFTER (Refactored with New Architecture):
+- ✅ Automatic authentication via createAuthenticatedHandler middleware
+- ✅ Standardized error responses with proper status codes and request IDs
+- ✅ Strong input validation with Zod schemas and type safety
+- ✅ Built-in rate limiting (60 req/min) with configurable limits
+- ✅ Automatic audit logging for security compliance
+- ✅ Automatic pagination handling via middleware
+- ✅ Consistent API response format with metadata
+- ✅ Comprehensive error handling with proper categorization
+- ✅ Automatic company access validation for multi-tenant security
+- ✅ Performance optimization: parallel database queries
+
+BENEFITS:
+1. **Consistency**: All endpoints follow the same patterns
+2. **Security**: Built-in auth, rate limiting, audit logging, company isolation
+3. **Maintainability**: Less boilerplate, centralized logic, type safety
+4. **Performance**: Optimized queries, caching headers, parallel execution
+5. **Developer Experience**: Better error messages, validation, debugging
+6. **Scalability**: Standardized patterns that can be applied across all endpoints
+
+MIGRATION STRATEGY:
+1. Replace the original route.ts with this refactored version
+2. Update any frontend code to expect the new response format
+3. Test thoroughly to ensure backward compatibility where needed
+4. Repeat this pattern for other endpoints
