# File Modification Boundaries

You are implementing the OMS (Order Management System) for the NT8 SDK project.

## Allowed Modifications

You MAY create and modify files in these directories ONLY:

### Core OMS Implementation
- `src/NT8.Core/OMS/*.cs` - All OMS implementation files
- `src/NT8.Core/OMS/**/*.cs` - Any subdirectories under OMS

### Testing
- `tests/NT8.Core.Tests/OMS/*.cs` - OMS unit tests
- `tests/NT8.Core.Tests/OMS/**/*.cs` - OMS test subdirectories
- `tests/NT8.Core.Tests/Mocks/*.cs` - Mock implementations (MockNT8OrderAdapter)

## Strictly Forbidden Modifications

You MUST NOT modify any existing files in these locations:

### Core Interfaces and Models
- `src/NT8.Core/Common/**` - Existing interfaces and base models
- `src/NT8.Core/Risk/**` - Risk management system (completed)
- `src/NT8.Core/Sizing/**` - Position sizing system (completed)
- `src/NT8.Core/Logging/**` - Logging infrastructure

### Build Configuration
- `Directory.Build.props` - Global build properties
- `*.csproj` files - Project files (unless adding new files to OMS project)
- `.gitignore`

### Documentation (Read-Only)
- `nt8_phasing_plan.md`
- `nt8_dev_spec.md`
- `NT8_Integration_Guidelines_for_AI_Agents.md`
- `AI_Agent_Workflow_and_Code_Templates.md`

### NT8 Adapters
- `src/NT8.Adapters/**` - NT8 integration (future phase)

## New File Creation Rules

### When creating new files:
1. Use proper namespace: `NT8.Core.OMS` for implementation, `NT8.Core.Tests.OMS` for tests
2. Include XML documentation on all public members
3. Follow existing file naming patterns (PascalCase, descriptive names)
4. Add to appropriate project file if needed

### File naming examples:
✅ `BasicOrderManager.cs` - Implementation class
✅ `OrderModels.cs` - Model classes
✅ `IOrderManager.cs` - Interface
✅ `BasicOrderManagerTests.cs` - Test class
✅ `MockNT8OrderAdapter.cs` - Mock for testing

## Verification
Before any file operation, ask yourself:
1. Is this file in an allowed directory?
2. Am I modifying an existing Core interface? (FORBIDDEN)
3. Am I creating a new file in the correct location?

If unsure, DO NOT proceed - ask for clarification first.
