|
|
- **Impact**: Medium - May require adapter or migration
|
|
- **Recommendation**: Update implementation to use `Microsoft.Extensions.Logging` as specified
|
|
|
|
2. **Method Signatures**: Some method signatures differ slightly from specification

## Detailed Gap Analysis
|
|
|
|
### Gap 1: Logging Framework Inconsistency
|
|
**Location**: Risk Management and Position Sizing components
|
|
**Description**: Implementation uses custom `ILogger` interface instead of `Microsoft.Extensions.Logging`
|
|
**Files Affected**:
|
|
- src/NT8.Core/Risk/BasicRiskManager.cs
|
|
- src/NT8.Core/Sizing/BasicPositionSizer.cs
|
|
- src/NT8.Core/Common/Interfaces/IStrategy.cs (indirectly)
|
|
**Recommendation**:
|
|
1. Update to use `Microsoft.Extensions.Logging` as specified
|
|
2. If custom logger is preferred, ensure it's compatible with Microsoft's logging extensions
|
|
|
|
### Gap 2: Method Signature Differences
|
|
**Location**: Risk Management and Position Sizing components
|
|
**Description**: Some method signatures use different parameter names or patterns than specification
|
|
**Files Affected**:
|
|
- src/NT8.Core/Risk/BasicRiskManager.cs
|
|
- src/NT8.Core/Sizing/BasicPositionSizer.cs
|
|
**Examples**:
|
|
- Parameter names in constructors use different casing
|
|
- Dictionary initialization syntax differs
|
|
**Recommendation**: Align method signatures with specification for consistency
|
|
|
|
### Gap 3: Missing Validation Scripts
|
|
**Location**: Tools directory
|
|
**Description**: PowerShell validation scripts specified but not implemented
|
|
**Files Missing**:
|
|
- tools/validate-risk-implementation.ps1
|
|
- tools/validate-sizing-implementation.ps1
|
|
- Specs/SDK/complete_validation_script.txt (implementation exists but not as script)
|
|
**Recommendation**: Implement validation scripts as specified
|
|
|
|
### Gap 4: Incomplete Documentation
|
|
**Location**: Docs directory
|
|
**Description**: Some documentation sections specified but not implemented
|
|
**Files Missing**:
|
|
- API documentation
|
|
- Deployment guides
|
|
- Developer setup guides
|
|
**Recommendation**: Complete all documentation as specified
|
|
|
|
## Recommendations
|
|
|
|
### Priority 1 (High Impact):
|
|
1. **Align Logging Framework**: Update implementation to use `Microsoft.Extensions.Logging` as specified
|
|
2. **Implement Validation Scripts**: Create PowerShell validation scripts for automated testing
|
|
|
|
### Priority 2 (Medium Impact):
|
|
1. **Align Method Signatures**: Update method signatures to match specifications exactly
|
|
2. **Complete Documentation**: Create missing documentation files
|
|
|
|
### Priority 3 (Low Impact):
|
|
1. **Minor Code Style Improvements**: Align code style with specifications where differences exist
|
|
|
|
## Conclusion
|
|
The NT8 Institutional SDK Phase 0 implementation is largely complete and functional, with core components implemented according to specifications. The main gaps are in peripheral areas such as logging framework alignment, validation scripts, and documentation completeness. These gaps do not significantly impact core functionality but should be addressed for full compliance with specifications.
|
|
|
|
The implementation demonstrates strong architectural principles and follows the specified design patterns. Test coverage is comprehensive and risk management/position sizing components are functional. The gaps identified are primarily about alignment with specifications rather than functional deficiencies.
