# Task 5: Integrate with ProjectManagement Module

**Story**: Story 1 - Audit Log Foundation (Phase 1)
**Estimated**: 3 hours

## Description

Integrate the audit logging infrastructure with the existing ProjectManagement Module to ensure all Epic/Story/Task operations are automatically audited.

## Acceptance Criteria

- [ ] Audit logging works for Project CRUD operations
- [ ] Audit logging works for Epic CRUD operations
- [ ] Audit logging works for Story CRUD operations
- [ ] Audit logging works for Task CRUD operations
- [ ] Integration tests verify audit logs are created
- [ ] No performance degradation (< 5ms overhead)

## Implementation Details

**No Code Changes Required** - The EF Core Interceptor automatically captures all changes!

**Verification Steps**:

1. **Run Integration Tests**:
```bash
cd colaflow-api
dotnet test --filter "FullyQualifiedName~ProjectManagement.IntegrationTests"
```

2. **Verify Audit Logs Created**:
- Create a Project → Check AuditLog table for "Create" entry
- Update an Epic → Check AuditLog table for "Update" entry
- Delete a Story → Check AuditLog table for "Delete" entry

3. **Performance Benchmark**:
```csharp
// Add to integration tests
[Fact]
public async Task CreateProject_ShouldHaveMinimalPerformanceOverhead()
{
    // Measure time with audit logging enabled
    var stopwatch = Stopwatch.StartNew();
    await Mediator.Send(new CreateProjectCommand { /* ... */ });
    stopwatch.Stop();

    Assert.True(stopwatch.ElapsedMilliseconds < 100, "Project creation took too long");
}
```

**Files to Update**:

1. **Integration Test Verification**: `colaflow-api/tests/ColaFlow.Application.IntegrationTests/ProjectManagement/AuditLogIntegrationTests.cs`
```csharp
public class AuditLogIntegrationTests : IntegrationTestBase
{
    [Fact]
    public async Task CreateProject_ShouldCreateAuditLog()
    {
        // Arrange
        var command = new CreateProjectCommand
        {
            Name = "Test Project",
            Key = "TEST",
            Description = "Test Description"
        };

        // Act
        var projectId = await Mediator.Send(command);

        // Assert
        var auditLogs = await Context.AuditLogs
            .Where(a => a.EntityType == "Project" && a.EntityId == projectId)
            .ToListAsync();

        Assert.Single(auditLogs);
        Assert.Equal(AuditAction.Create, auditLogs[0].Action);
        Assert.Equal(TenantId, auditLogs[0].TenantId);
    }

    [Fact]
    public async Task UpdateEpic_ShouldCreateAuditLog_WithOldAndNewValues()
    {
        // Create Epic first
        var epicId = await CreateTestEpic();

        // Update Epic
        await Mediator.Send(new UpdateEpicCommand
        {
            EpicId = epicId,
            Title = "Updated Title"
        });

        // Assert audit log created
        var auditLogs = await Context.AuditLogs
            .Where(a => a.EntityType == "Epic" && a.EntityId == epicId && a.Action == AuditAction.Update)
            .ToListAsync();

        Assert.Single(auditLogs);
        Assert.NotNull(auditLogs[0].OldValues);
        Assert.NotNull(auditLogs[0].NewValues);
    }

    [Fact]
    public async Task DeleteTask_ShouldCreateAuditLog()
    {
        // Test delete operation audit logging
        // ...
    }
}
```

## Technical Notes

- The SaveChangesInterceptor automatically captures all EF Core operations
- No changes to Command Handlers required
- Verify multi-tenant isolation works correctly
- Check audit logs in database after each operation

## Testing

**Integration Tests to Create**:
1. Project Create/Update/Delete audit logging
2. Epic Create/Update/Delete audit logging
3. Story Create/Update/Delete audit logging
4. Task Create/Update/Delete audit logging
5. Multi-tenant isolation verification
6. Performance overhead verification (< 5ms)

**Run Tests**:
```bash
dotnet test --filter "FullyQualifiedName~AuditLogIntegration"
```

## Definition of Done

- All 4 entity types (Project/Epic/Story/Task) are audited
- Integration tests verify audit logs are created
- Multi-tenant isolation verified
- Performance benchmark met (< 5ms overhead)
- Git commit created
