**Motivations :**
* Create a complete simulator for 4NK Waste & Water modular waste treatment infrastructure
* Implement frontend-only application with client-side data persistence
* Provide seed data for wastes and natural regulators from specifications
**Root causes :**
* Need for a simulation tool to configure and manage waste treatment projects
* Requirement for localhost-only access with persistent client-side storage
* Need for initial seed data to bootstrap the application
**Correctifs :**
* Implemented authentication system with AuthContext
* Fixed login/logout functionality with proper state management
* Created placeholder pages for all routes
**Evolutions :**
* Complete application structure with React, TypeScript, and Vite
* Seed data for 9 waste types and 52 natural regulators
* Settings page with import/export and seed data loading functionality
* Configuration pages for wastes and regulators with CRUD operations
* Project management pages structure
* Business plan and yields pages placeholders
* Comprehensive UI/UX design system (dark mode only)
* Navigation system with sidebar and header
**Page affectées :**
* All pages: Login, Dashboard, Waste Configuration, Regulators Configuration, Services Configuration
* Project pages: Project List, Project Configuration, Treatment Sites, Waste Sites, Investors, Administrative Procedures
* Analysis pages: Yields, Business Plan
* Utility pages: Settings, Help
* Components: Layout, Sidebar, Header, base components (Button, Input, Select, Card, Badge, Table)
* Utils: Storage, seed data, formatters, validators, constants
* Types: Complete TypeScript definitions for all entities
