## Core Interfaces

### ILearningOrchestrator

Main orchestration service interface for coordinating learning sessions.

```csharp
public interface ILearningOrchestrator : IDisposable
{
    /// <summary>
    /// Executes a complete learning session with all phases
    /// </summary>
    /// <param name="session">Learning session configuration</param>
    /// <returns>Comprehensive results with metrics and analysis</returns>
    Task<ComprehensiveLearningResult> ExecuteCompleteLearningSessionAsync(
        ComprehensiveLearningSession session);
}
```

**Implementation**: `LearningOrchestrator`  
**Lifecycle**: Transient (create per session)  
**Thread Safety**: Single-threaded per instance

## Service Implementations

### LearningOrchestrator

```csharp
public class LearningOrchestrator : ILearningOrchestrator, IDisposable
{
    // Constructor with dependency injection
    public LearningOrchestrator(
        ILogger<LearningOrchestrator> logger,
        IOptions<LearningConfiguration> configOptions,
        ISecurityService securityService,
        ILLMContextService llmContextService,
        IUnifiedContextService unifiedContextService,
        GitManager gitManager,
        CompilationManager compilationManager,
        ReportsManager reportsManager,
        RefactorIQIntegration refactorIQIntegration);

    // Main execution method
    public async Task<ComprehensiveLearningResult> ExecuteCompleteLearningSessionAsync(
        ComprehensiveLearningSession session);

    // Proper disposal pattern
    public void Dispose();
    protected virtual void Dispose(bool disposing);
}
```

**Key Features:**
- **Phase-based execution**: Git setup → Analysis → Iterations → Reporting
- **Correlation ID tracking**: Traces operations across service calls
- **Resource management**: Proper disposal of all resources
- **Security integration**: Validates all inputs and file access
- **Error recovery**: Handles failures gracefully with detailed reporting

### UnifiedContextService

```csharp
public class UnifiedContextService : IUnifiedContextService
{
    // Constructor
    public UnifiedContextService(
        ILLMContextService llmContextService,
        IOptions<LearningConfiguration> options,
        ILogger<UnifiedContextService> logger);

    // Core context preparation method
    public async Task<ComprehensiveContext> PrepareFullContextAsync(
        string query, 
        string? filePath = null, 
        int maxTokens = 8000);
}
```

**Key Features:**
- **Context combination**: Merges real-time and historical data
- **Token optimization**: Respects LLM token limits intelligently
- **Caching**: Performance optimization with concurrent cache
- **Mock integration**: Ready for Context project when available

}
```

## Usage Examples

### Basic Learning Session

```csharp
// Setup dependency injection
var services = new ServiceCollection();
services.AddSingleton<IUnifiedContextService, UnifiedContextService>();
services.AddSingleton<ILLMContextService, LLMContextService>();
services.AddSingleton<ISecurityService, SecurityService>();
services.AddTransient<ILearningOrchestrator, LearningOrchestrator>();

var serviceProvider = services.BuildServiceProvider();

// Create and execute learning session
var session = new ComprehensiveLearningSession
{
    SessionId = Guid.NewGuid(),
    SolutionPath = @"C:\MyProject\Solution.sln",
    LearningMode = "moderate",
    EnableSemanticSearch = true,
    MaxIterations = 25,
    SessionTimeoutMinutes = 90
};

using var orchestrator = serviceProvider.GetRequiredService<ILearningOrchestrator>();
var result = await orchestrator.ExecuteCompleteLearningSessionAsync(session);

// Process results
Console.WriteLine($"Session completed: {result.Success}");
Console.WriteLine($"Duration: {result.TotalDuration.TotalMinutes:F1} minutes");
Console.WriteLine($"Iterations: {result.Iterations.Count}");
Console.WriteLine($"Successful: {result.Iterations.Count(i => i.Success)}");
```

### Advanced Context Preparation

```csharp
var contextService = serviceProvider.GetRequiredService<IUnifiedContextService>();

// Initialize learning session
var sessionContext = await contextService.InitializeLearningSessionAsync(
    projectPath: @"C:\MyProject",
    topic: "Performance optimization and code cleanup"
);

// Prepare comprehensive context for specific task
var context = await contextService.PrepareFullContextAsync(
    query: "optimize database access patterns in UserService",
    filePath: @"C:\MyProject\Services\UserService.cs",
    maxTokens: 12000
);

// Analyze the context
Console.WriteLine($"Current code analysis tokens: {context.CurrentCodeAnalysis?.EstimatedTokens}");
Console.WriteLine($"Historical insights: {context.HistoricalInsights.Count}");
Console.WriteLine($"Related decisions: {context.RelatedDecisions.Count}");

// Check for successful patterns from history
var successfulDecisions = context.RelatedDecisions.Where(d => d.Successful).ToList();
if (successfulDecisions.Any())
{
    Console.WriteLine("Found successful patterns:");
    foreach (var decision in successfulDecisions.Take(3))
    {
        Console.WriteLine($"  - {decision.Summary} (Relevance: {decision.Relevance:P})");
    }
}

// Store insight about this analysis
await contextService.StoreLearningInsightAsync(
    insight: "UserService has complex database access patterns that could benefit from caching",
    category: "performance-analysis",
    filePath: @"C:\MyProject\Services\UserService.cs",
    metadata: new Dictionary<string, object>
    {
        ["analysisTimestamp"] = DateTime.UtcNow,
        ["complexityScore"] = 0.85,
        ["recommendedPattern"] = "cache-aside"
    }
);
```

### Security Validation

```csharp
var securityService = serviceProvider.GetRequiredService<ISecurityService>();

// Validate file access
string filePath = @"C:\MyProject\Services\UserService.cs";
if (!securityService.IsPathSafe(filePath))
{
    throw new SecurityException("PathValidation", filePath, "File path is not safe");
}

if (!securityService.IsFileAllowed(filePath))
{
    throw new SecurityException("FileAccess", filePath, "File access not allowed");
}

// Sanitize user input
string userQuery = securityService.SanitizeInput(rawUserInput);

// Validate configuration
var config = serviceProvider.GetRequiredService<IOptions<LearningConfiguration>>().Value;
var validationResult = securityService.ValidateConfiguration(config);

if (!validationResult.IsValid)
{
    foreach (var error in validationResult.Errors)
    {
        Console.WriteLine($"Configuration error: {error}");
    }
}
```

### Error Handling

```csharp
try
{
    var result = await orchestrator.ExecuteCompleteLearningSessionAsync(session);
}
catch (CompilationException ex)
{
    Console.WriteLine($"Compilation failed: {ex.ErrorCount} errors, {ex.WarningCount} warnings");
    foreach (var error in ex.Errors.Take(5))
    {
        Console.WriteLine($"  - {error}");
    }
}
catch (SecurityException ex)
{
    Console.WriteLine($"Security violation in {ex.ValidationType}: {ex.Message}");
    // Log security incident
}
catch (AIServiceException ex)
{
    Console.WriteLine($"AI service {ex.ServiceName} failed: {ex.Message}");
    if (ex.IsRetryable)
    {
        Console.WriteLine("This operation can be retried");
    }
}
catch (LearningException ex)
{
    Console.WriteLine($"Learning operation failed in {ex.OperationContext}: {ex.Message}");
    Console.WriteLine($"Correlation ID: {ex.CorrelationId}");
}
```

### Plugin Usage

```csharp
// Using the main learning plugin
var plugin = new ComprehensiveLearningRefactorPlugin();

var parameters = new Dictionary<string, object>
{
    ["solutionPath"] = @"C:\MyProject\Solution.sln",
    ["learningMode"] = "aggressive",
    ["enableSemanticSearch"] = true,
    ["openAIApiKey"] = Environment.GetEnvironmentVariable("OPENAI_API_KEY"),
    ["maxIterations"] = 30,
    ["sessionTimeoutMinutes"] = 120,
    ["verboseReporting"] = true
};

var result = await plugin.ExecuteAsync(parameters);

if (result.Success)
{
    var learningResult = (ComprehensiveLearningResult)result.Data;
    Console.WriteLine($"Learning session completed successfully");
    Console.WriteLine($"Project: {learningResult.ProjectName}");
    Console.WriteLine($"Duration: {learningResult.TotalDuration}");
}
else
{
    Console.WriteLine($"Learning session failed: {result.Message}");
}
```
