🚨 Enterprise-Grade Error Handling

API Error Management

We've implemented comprehensive error handling across our API layer:

// Enhanced TigerGradesAPI error handling
class TigerGradesAPI {
    public function __construct() {
        try {
            $this->initializeAzureConnection();
        } catch (AuthenticationException $e) {
            $this->logError('Azure authentication failed', $e);
            $this->fallbackToLocalMode();
        } catch (Exception $e) {
            $this->logError('API initialization failed', $e);
            throw new TigerGradesException(
                'Unable to initialize Tiger Grades API: ' . $e->getMessage()
            );
        }
    }
    
    public function fetchReportCard($studentId, $classId) {
        try {
            return $this->performReportCardFetch($studentId, $classId);
        } catch (AzureServiceException $e) {
            $this->logError("Report card fetch failed for student {$studentId}", $e);
            return $this->generateErrorResponse($e);
        }
    }
}

Robust Logging System

// Enhanced error logging with context
class ErrorLogger {
    public function logError($message, $exception, $context = []) {
        $logEntry = [
            'timestamp' => current_time('mysql'),
            'message' => $message,
            'exception' => $exception->getMessage(),
            'trace' => $exception->getTraceAsString(),
            'context' => $context,
            'environment' => $this->getCurrentEnvironment()
        ];
        
        error_log(
            'Tiger Grades Error: ' . json_encode($logEntry),
            3,
            WP_CONTENT_DIR . '/logs/tiger-grades.log'
        );
    }
}

📚 Advanced Semester Management

Multi-Semester Architecture

v0.0.3 introduces sophisticated semester handling with tabbed interfaces for multi-semester courses:

// Dynamic semester tab functionality
class SemesterManager {
    constructor(container) {
        this.container = container;
        this.initializeTabs();
        this.bindEvents();
    }
    
    initializeTabs() {
        const semesters = this.getSemesters();
        semesters.forEach(semester => {
            this.createTab(semester);
            this.loadSemesterData(semester);
        });
    }
    
    switchSemester(semesterId) {
        this.hideAllTabs();
        this.showTab(semesterId);
        this.loadGrades(semesterId);
        this.updateBreadcrumbs(semesterId);
    }
}

Semester Features:

• 🗂️ Tabbed interface for easy semester navigation
• 📊 Semester-specific grading with isolated calculations
• 🎯 Progress tracking across academic periods
• 🔄 Seamless semester transitions with data persistence

🗄️ Database Architecture Enhancements

Dynamic Variable Processing

Our DatabaseManager now supports SQL variable processing:

class DatabaseManager {
    public function processVariables($sql) {
        // Replace @variables with actual values
        $variables = [
            '@current_semester' => $this->getCurrentSemesterId(),
            '@current_year' => date('Y'),
            '@site_url' => site_url()
        ];
        
        foreach ($variables as $variable => $value) {
            $sql = str_replace($variable, $value, $sql);
        }
        
        return $sql;
    }
    
    public function executeMigration($migrationFile) {
        $sql = file_get_contents($migrationFile);
        $sql = $this->processVariables($sql);
        
        return $this->executeQuery($sql);
    }
}

Improved Seeding Strategy

-- Enhanced seed scripts with environment awareness
INSERT INTO wp_tigr_classes (title, teacher_id, semester_id, environment)
SELECT 
    'Sample Math Class',
    @teacher_id,
    @current_semester,
    @environment
WHERE @environment IN ('development', 'staging');

🎨 User Experience Improvements

Enhanced Grade Display Logic

We've refined the grade calculation and display system:

// Improved grade handling for various states
class GradeCalculator {
    calculateFinalGrade(grades, categories) {
        const processedGrades = grades.map(grade => {
            switch(grade.status) {
                case 'exempt':
                    return this.handleExemptGrade(grade);
                case 'empty':
                    return this.handleEmptyGrade(grade);
                case 'completed':
                    return this.handleCompletedGrade(grade);
                case 'zero':
                    return this.handleZeroGrade(grade);
                default:
                    return this.handleStandardGrade(grade);
            }
        });
        
        return this.weightedAverage(processedGrades, categories);
    }
    
    handleScienceGradeTypes(grade) {
        // STEM-specific grading logic
        const stemCategories = ['Lab', 'Theory', 'Project', 'Assessment'];
        return stemCategories.includes(grade.category) 
            ? this.applyStemWeighting(grade)
            : this.applyStandardWeighting(grade);
    }
}

Case-Sensitive Grade Types

Enhanced support for diverse grading systems:

• STEM-specific grade categories (Lab, Theory, Project)
• Case-sensitive grade type handling
• Subject-specific weighting algorithms
• Flexible grading schema support
