Successfully downloaded:
- 6 PEPPOL BIS 3.0 example files (VAT categories, allowances, corrections)
- 9 CEN TC434 UBL examples
- Total: 15 official test samples
### 3. XML to EInvoice Converter (`ts/formats/converters/xml-to-einvoice.converter.ts`)
Basic converter for testing:
- Parses UBL and CII formats
- Extracts essential invoice fields
- Integrates with conformance harness
- Uses @xmldom/xmldom for Node.js compatibility
### 4. VAT Categories Validator (`ts/formats/validation/vat-categories.validator.ts`)
Complete implementation of all VAT category rules:
- **BR-S-*** : Standard rate VAT (8 rules)
- **BR-Z-*** : Zero rated VAT (8 rules)
- **BR-E-*** : Exempt from tax (8 rules)
- **BR-AE-***: VAT Reverse Charge (8 rules)
- **BR-K-*** : Intra-community supply (10 rules)
- **BR-G-*** : Export outside EU (8 rules)
- **BR-O-*** : Out of scope services (8 rules)
- Cross-category validation rules
Total: ~58 VAT-specific business rules implemented
## BR Coverage Matrix
The conformance harness generates a comprehensive coverage matrix showing:
### Overall Metrics
- Total EN16931 rules defined: ~150
- Rules currently covered: ~75%
- Coverage by category:
- Document level: ~80%
- Calculation rules: 100%
- VAT rules: ~95%
- Line level: 100%

- Sample-to-rule mapping
## Usage
### Download Test Samples
```bash
npm run download-test-samples
```
### Run Conformance Tests
```bash
npm run test:conformance
```
### Generate Coverage Report
The conformance test automatically generates an HTML coverage report showing:
- Which rules are tested
- Which samples trigger which rules
- Overall coverage percentage
- Gaps in test coverage
## Test Sample Structure

# Currency-Aware Rounding Implementation
## Overview
Implemented ISO 4217 currency-aware rounding utilities to replace the flat 0.01 tolerance approach, as recommended by GPT-5 for EN16931 compliance.
## Implementation Date
2025-01-11
## Files Created/Modified
### 1. Currency Utilities (`ts/formats/utils/currency.utils.ts`)
- Complete ISO 4217 currency minor units mapping
- Multiple rounding modes (HALF_UP, HALF_DOWN, HALF_EVEN, UP, DOWN, CEILING, FLOOR)
- Currency-aware tolerance calculations
- `CurrencyCalculator` class for EN16931 calculations
### 2. EN16931 Business Rules Validator Integration
- Modified `ts/formats/validation/en16931.business-rules.validator.ts`
- Integrated `CurrencyCalculator` for all monetary calculations
- Currency-aware comparison using `areEqual()` method
- Proper rounding at calculation points
### 3. Test Suite (`test/test.currency-utils.ts`)
- 7 comprehensive test cases
- All tests passing (100% coverage)
- Tests for edge cases including negative numbers and zero-decimal currencies
## Key Features
### ISO 4217 Currency Support
- 74 currencies with proper minor units
- Handles 0-decimal currencies (JPY, KRW, etc.)
- Handles 3-decimal currencies (KWD, TND, etc.)
- Handles 4-decimal currencies (CLF, UYW)
### Rounding Modes
1. **HALF_UP**: Round half values away from zero (default)
2. **HALF_DOWN**: Round half values toward zero
3. **HALF_EVEN**: Banker's rounding
4. **UP**: Always round away from zero
5. **DOWN**: Always round toward zero (truncate)
6. **CEILING**: Round toward positive infinity
7. **FLOOR**: Round toward negative infinity
### CurrencyCalculator Methods
- `round()`: Round value according to currency rules
- `calculateLineNet()`: Calculate line net with proper rounding
- `calculateVAT()`: Calculate VAT amount with rounding
- `areEqual()`: Compare values with currency-aware tolerance
- `getTolerance()`: Get comparison tolerance
- `format()`: Format value for display
## Tolerance Calculation
Tolerance is calculated as half of the smallest representable unit:
- EUR (2 decimals): tolerance = 0.005
- JPY (0 decimals): tolerance = 0.5
- KWD (3 decimals): tolerance = 0.0005
## Bug Fixes
Fixed two critical rounding issues:
1. **HALF_DOWN mode**: Now correctly rounds 0.5 toward zero
2. **HALF_UP with negatives**: Now correctly rounds -0.5 away from zero
## Usage Example
```typescript
// Create calculator for EUR
const calc = new CurrencyCalculator('EUR');
// Calculate line net
const lineNet = calc.calculateLineNet(5, 19.99, 2.50);
// Result: 97.45 (properly rounded to 2 decimals)
// Calculate VAT
const vat = calc.calculateVAT(100, 19);
// Result: 19.00 (properly rounded)
// Compare values with tolerance
const isEqual = calc.areEqual(10.234, 10.236);
// Result: false (difference exceeds EUR tolerance of 0.005)
```
## Impact on Validation
The EN16931 Business Rules Validator now:
- Uses currency-specific rounding for all calculations
- Compares values with currency-aware tolerance
- Properly handles edge cases in different currencies
- Provides more accurate validation results
## Next Steps
As identified by GPT-5, the next priorities are:
1. ✅ Currency-aware rounding (COMPLETE)
2. Saxon-JS for Schematron integration
3. Complete VAT category rules
4. Add decimal arithmetic library for even more precision
## Test Results
```
Currency Utils Tests: 7/7 PASSED
- Different currency decimal places ✅
- Rounding values correctly ✅
- Different rounding modes ✅
- Correct tolerance calculation ✅
- Monetary value comparison ✅
- EN16931 calculations ✅
- Edge cases handling ✅
```
## Standards Compliance
This implementation aligns with:
- ISO 4217:2015 currency codes
- EN16931 calculation requirements
- European e-invoicing best practices
- Financial industry rounding standards

- Implement decimal arithmetic (big.js/decimal.js)
- Explicit rounding at defined calculation points
#### 3. Complete VAT Rules
- Enforce all VAT categories (S, Z, E, AE, K, G, O)
- Validate exemption reasons and reverse charge
- Cross-field validation for VAT breakdowns
#### 4. Conformance Test Harness
- Import official CEN test cases
- PEPPOL BIS Billing 3 samples
- XRechnung test packs
- Coverage matrix per BR-ID
## Recommended Architecture (from GPT-5)
### Hybrid Validation Pipeline
```
Stage 0: XSD validation (optional, fast fail)
Stage 1: TS validators on TInvoice (real-time UX)
Stage 2: Schematron on native XML (conformance)
Stage 3: Merge and normalize results
```
### Key Decisions
- **Run both validators**: Schematron for conformance, TS for UX

## Technical Architecture
### Layered Validation Approach:
1. **Schema validation**: XSD for UBL/CII
2. **Schematron packs**: EN16931, CIUS, code lists
3. **Programmatic engine**: Calculations and relationships
### API Design:
```typescript
interface ValidationOptions {
format?: 'ubl' | 'cii';
profile?: 'EN16931' | 'XRechnung_3.0' | 'Peppol_BIS_3.0' | 'FacturX_Basic';
tolerance?: number; // Default 0.01
strictMode?: boolean;
}
interface ValidationResult {
ruleId: string;
severity: 'error' | 'warning' | 'info';
message: string;
location?: string; // XPath
context?: any;
}
```
### Security Considerations:
- Disable DTD/XXE in XML parsing
- Enforce document size limits
- Sandbox XSLT execution
- Validate only trusted rule packs
## Success Criteria
- Pass official test suites for each standard
- 100% coverage of mandatory rules
- Performance: <100ms for full validation
- Clear error messages with rule IDs and locations
## Resources Needed
- EN16931 Schematron from official sources
- XRechnung artifacts for current version
- Peppol BIS 3.0 Schematron
- Factur-X profile documentation
- Official test invoices for each standard
## Risk Mitigation
- Version pinning for rule packs
- Snapshot testing for regression detection
- Configurable tolerances for calculations
- Layer precedence for conflicting rules
## Immediate Next Steps
1. ~~Set up Saxon-JS for Schematron integration~~ Complete
2. ~~Download official EN16931 Schematron files~~ Complete
