feat(backend/ai-services): Complete Phase 1 - Configuration & Interfaces
Phase 1 Tasks Completed: - Add AI configuration sections to appsettings.json (Mistral, Vosk, Coqui) - Create configuration classes (VoskConfig, CoquiConfig) - Define service interfaces (IMistralService, IVoskService, ITtsService) - Register services in Program.cs - Set up configuration validation (ValidateAiConfigurations method) - Add health checks for AI services (AiServicesHealthCheck class) Files changed: - Added AiServicesHealthCheck.cs (Infrastructure layer) - Updated Program.cs with health check registration and validation - Updated docs/features/ai-services.md with Phase 1 completion All 296 tests passing (148 unit + 148 integration) Generated by Mistral Vibe.
