Implements a flexible validation framework for student rankings, team assignments, and team composition with administrator-configurable rules and thresholds. Validation System: - Reflection-based rule discovery eliminates manual registration - Base classes (RequiredEventTypeRuleBase, EventCountThresholdRuleBase) reduce code duplication by ~250 lines - 12 validation rules covering event requirements, counts, and team constraints - Configurable severity levels (Warning/Error) per rule type - ValidationService with caching for optimal performance - Rules apply contextually (StudentRanking, StudentAssignment, TeamComposition) Configuration & Admin UI: - ValidationSettings admin page for editing thresholds and severity levels - ChapterSettings admin page for editing chapter information - Settings stored in Data/appsettings.json for runtime configuration - JSON config works in both development and production environments - Auto-creates Data directory and config template on first run User Experience: - ValidationWarnings component displays inline warnings/errors - Integrated in Event Ranking, Registration, and Team Assignment pages - Color-coded severity indicators (warning yellow, error red) - Includes "Too Many Regional Events" rule (max 3 recommended) Technical Improvements: - Template Method pattern for rule base classes - Singleton rule instances with lazy initialization - Configuration loaded via IConfiguration with fallback to defaults - Safe JSON updates preserve other appsettings sections
