feat: Geutebruck GeViScope/GeViSoft Action Mapping System - MVP
This MVP release provides a complete full-stack solution for managing action mappings in Geutebruck's GeViScope and GeViSoft video surveillance systems. ## Features ### Flutter Web Application (Port 8081) - Modern, responsive UI for managing action mappings - Action picker dialog with full parameter configuration - Support for both GSC (GeViScope) and G-Core server actions - Consistent UI for input and output actions with edit/delete capabilities - Real-time action mapping creation, editing, and deletion - Server categorization (GSC: prefix for GeViScope, G-Core: prefix for G-Core servers) ### FastAPI REST Backend (Port 8000) - RESTful API for action mapping CRUD operations - Action template service with comprehensive action catalog (247 actions) - Server management (G-Core and GeViScope servers) - Configuration tree reading and writing - JWT authentication with role-based access control - PostgreSQL database integration ### C# SDK Bridge (gRPC, Port 50051) - Native integration with GeViSoft SDK (GeViProcAPINET_4_0.dll) - Action mapping creation with correct binary format - Support for GSC and G-Core action types - Proper Camera parameter inclusion in action strings (fixes CrossSwitch bug) - Action ID lookup table with server-specific action IDs - Configuration reading/writing via SetupClient ## Bug Fixes - **CrossSwitch Bug**: GSC and G-Core actions now correctly display camera/PTZ head parameters in GeViSet - Action strings now include Camera parameter: `@ PanLeft (Comment: "", Camera: 101028)` - Proper filter flags and VideoInput=0 for action mappings - Correct action ID assignment (4198 for GSC, 9294 for G-Core PanLeft) ## Technical Stack - **Frontend**: Flutter Web, Dart, Dio HTTP client - **Backend**: Python FastAPI, PostgreSQL, Redis - **SDK Bridge**: C# .NET 8.0, gRPC, GeViSoft SDK - **Authentication**: JWT tokens - **Configuration**: GeViSoft .set files (binary format) ## Credentials - GeViSoft/GeViScope: username=sysadmin, password=masterkey - Default admin: username=admin, password=admin123 ## Deployment All services run on localhost: - Flutter Web: http://localhost:8081 - FastAPI: http://localhost:8000 - SDK Bridge gRPC: localhost:50051 - GeViServer: localhost (default port) Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
