**Motivations :**
* Allow associating administrative procedures to module components with status tracking
* Centralize regulation characteristics configuration for better data consistency
* Link regulation characteristics to wastes, regulators, ecosystems, and module components
**Root causes :**
* Need to track administrative procedures per module component
* Regulation characteristics were hardcoded in multiple places, causing inconsistency
* No centralized way to manage and reference regulation characteristics
**Correctifs :**
* Added ModuleComponentProcedureAssociation interface with procedureId, status, and notes
* Created RegulationCharacteristic entity with name, code, category, description, unit, isBoolean, minValue, maxValue
* Added regulationCharacteristicIds field to Waste, NaturalRegulator, Ecosystem, and ModuleComponent
* Updated all configuration pages to use regulation characteristics from centralized configuration
* Created RegulationCharacteristicsConfigurationPage for managing characteristics
* Added seeds for regulation characteristics (31 characteristics covering all categories)
* Added seeds for companies (4NK Water & Waste default company)
**Evolutions :**
* Module components can now have associated administrative procedures with status (toDo, done, na)
* Regulation characteristics are now centralized and can be referenced by multiple entities
* All regulation needs and characteristics are now managed through a single configuration page
* Business plans can be added to all entities (already implemented, documented in data_schemas.md)
* Updated data_schemas.md with complete documentation of all entities, relations, and validation rules
**Page affectées :**

* data_schemas.md - Complete documentation update
* data/seeds/regulation-characteristics-seeds.json - New seed file
* data/seeds/companies-seeds.json - New seed file
**Motivations :**
* Allow associating transporters to waste sites and treatment sites
* Allow associating services to module components
* Improve data relationships for better project management
**Evolutions :**
* Added SiteTransporterAssociation interface for site-transporter relationships
* Added ModuleComponentServiceAssociation interface for component-service relationships
* Added transporters field to TreatmentSite and WasteSite interfaces
* Added services field to ModuleComponent interface
* Updated WasteSitesPage and TreatmentSitesPage to manage transporters with primary flag and notes
* Updated ModuleComponentsConfigurationPage to manage services with notes
* Added CSS styles for transporter and service association sections
* Added transporters and services columns in respective tables

**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
