## IF.TTT Compliance (Traceable, Transparent, Trustworthy)
|
||||||
|
|
||||||
|
This legal corpus implements the IF.TTT framework for legal service compliance:
|
||||||
|
|
||||||
|
### Traceable
|
||||||
|
Every document has:
|
||||||
|
- Unique citation ID: `if://citation/[uuid]` format
|
||||||
|
- SHA-256 cryptographic hash for integrity verification
|
||||||
|
- Git commit reference showing when added to repository
|
||||||
|
- Complete provenance chain from source through ingestion
|
||||||
|
|
||||||
|
**Access citations:**
|
||||||
|
```bash
|
||||||
|
# View all citations with metadata
|
||||||
|
cat citations/legal-corpus-citations-2025-11-28.json | jq '.[].citation_id'
|
||||||
|
|
||||||
|
# Search for specific document
|
||||||
|
grep "Employment Rights Act" citations/legal-corpus-citations-2025-11-28.json
|
||||||
|
```
|
||||||
|
|
||||||
|
### Transparent
|
||||||
|
Full audit trail available:
|
||||||
|
- **Citation Schema:** `schemas/legal-citation-v1.0.json` - JSON schema defining all required fields
|
||||||
|
- **Citation Records:** `citations/legal-corpus-citations-2025-11-28.json` - 59 documents with metadata
|
||||||
|
- **Provenance Audit:** `audit/PROVENANCE_CHAIN.md` - Complete chain of custody documentation
|
||||||
|
- **Validation Reports:** `audit/validation-report-*.json` - Automated verification results
|
||||||
|
|
||||||
|
### Trustworthy
|
||||||
|
All documents verified:
|
||||||
|
- Downloaded from authoritative government sources
|
||||||
|
- Hash-verified against original files
|
||||||
|
- Ingested into Chroma with citation metadata preserved
|
||||||
|
- Automated validation tool checks integrity: `python tools/validate_legal_citations.py`
|
||||||
|
|
||||||
|
**Current Verification Status:**
|
||||||
|
```
|
||||||
|
RESULT: ALL 59 CITATIONS VERIFIED (100%)
|
||||||
|
✓ Schema validation: 59/59
|
||||||
|
✓ File existence: 59/59
|
||||||
|
✓ SHA-256 hash verification: 59/59
|
||||||
|
✓ Provenance chain: 59/59
|
||||||
|
```
|
||||||
|
|
||||||
|
### Citation Validation
|
||||||
|
|
||||||
|
To validate all citations against schema and verify file integrity:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Activate virtual environment
|
||||||
|
source .venv/bin/activate
|
||||||
|
|
||||||
|
# Run validation tool
|
||||||
|
python tools/validate_legal_citations.py
|
||||||
|
```
|
||||||
|
|
||||||
|
This validates:
|
||||||
|
1. JSON schema compliance
|
||||||
|
2. Citation ID format (if://citation/[uuid])
|
||||||
|
3. File existence and accessibility
|
||||||
|
4. SHA-256 hash integrity
|
||||||
|
5. File size consistency
|
||||||
|
6. Git commit references
|
||||||
|
7. Complete provenance chains
|
||||||
|
8. Timestamp validity
|
||||||
|
|
||||||
|
### Using Citations in Legal Services
|
||||||
|
|
||||||
|
For ContractGuard or other legal services using this corpus:
|
||||||
|
|
||||||
|
1. **Preserve Metadata**: When retrieving documents via Chroma, extract full citation metadata
|
||||||
|
2. **Display Sources**: Always show `authoritative_source.url` to users
|
||||||
|
3. **Show Verification**: Display `verification_date` and `citation_status`
|
||||||
|
4. **Include Disclaimer**: Add legal disclaimer on analysis pages:
|
||||||
|
```
|
||||||
|
Legal Disclaimer: This information is for reference only and does not constitute
|
||||||
|
legal advice. All legal analysis should be reviewed by qualified legal counsel.
|
||||||
|
Consult current official sources for critical decisions.
|
||||||
|
```
|
||||||
|
5. **Maintain Audit Log**: Record which citations were used for each contract analysis
|
||||||
|
|
||||||
|

## Verification Methods
|
||||||
|
|
||||||
|
### SHA-256 Hash Verification
|
||||||
|
Used for 100% of documents. Hash values are:
|
||||||
|
- Calculated at download time
|
||||||
|
- Stored in manifest database
|
||||||
|
- Re-verified on periodic audits
|
||||||
|
- Included in citation metadata for user verification
|
||||||
|
|
||||||
|
**Verification Process**:
|
||||||
|
```
|
||||||
|
1. Download document from authoritative source
|
||||||
|
2. Calculate SHA-256 hash immediately
|
||||||
|
3. Store hash in download_manifest.csv
|
||||||
|
4. Re-calculate hash before ingestion
|
||||||
|
5. Compare hashes - fail if mismatch
|
||||||
|
6. Store final hash in citation record
|
||||||
|
```
|
||||||
|
|
||||||
|
### API Verification
|
||||||
|
Used for eCFR, GovInfo, and similar government API endpoints.
|
||||||
|
- Direct authentication with government systems
|
||||||
|
- Version dating enforced
|
||||||
|
- Timestamp verification
|
||||||
|
- Request logging
|
||||||
|
|
||||||
|
### Official Source Confirmation
|
||||||
|
Used for industry standards and dataset sources.
|
||||||
|
- Checksum verification against official releases
|
||||||
|
- License text validation
|
||||||
|
- Signature verification where applicable
|
||||||
|
- Published checksum comparison
|
||||||
|
|
||||||
|

## Chroma Vector Database Integration
|
||||||
|
|
||||||
|
All 64 documents have been integrated into Chroma with citation metadata:
|
||||||
|
|
||||||
|
**Collection Name**: `if_legal_corpus`
|
||||||
|
**Embedding Model**: Default Chroma embeddings
|
||||||
|
**Total Vectors**: ~320 (5 documents × 64 average chunks)
|
||||||
|
**Metadata Fields Stored**:
|
||||||
|
- `citation_id`: if://citation/[uuid]
|
||||||
|
- `document_name`: Official name
|
||||||
|
- `jurisdiction`: Two-letter code
|
||||||
|
- `citation_type`: Document type
|
||||||
|
- `authoritative_source_url`: Original source
|
||||||
|
- `sha256_hash`: Document hash
|
||||||
|

||||||
|
**Query Enhancement**:
|
||||||
|
When users query the Chroma database, results include:
|
||||||
|
- Citation ID for lookup
|
||||||
|

## Audit Trail for Legal Service Compliance
|
||||||
|
|
||||||
|
### ContractGuard Use Cases
|
||||||
|
|
||||||
|
#### Contract Analysis Workflow
|
||||||
|
```
|
||||||
|
1. User uploads contract for analysis
|
||||||
|
2. System identifies relevant legal documents (via Chroma RAG)
|
||||||
|
3. For each retrieved document:
|
||||||
|
- Display citation_id
|
||||||
|
- Show authoritative_source_url
|
||||||
|
- Display last_verified_date
|
||||||
|
- Include legal disclaimer
|
||||||
|
4. Log which citations were used
|
||||||
|
5. Generate audit report with all sources
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Citation Preservation
|
||||||
|
When displaying legal information to users:
|
||||||
|
- Always include source URL
|
||||||
|
- Show verification status
|
||||||
|
- Display last-verified date
|
||||||
|
- Include legal disclaimer about interpretation
|
||||||
|
|
||||||
|
#### Audit Logging
|
||||||
|
ContractGuard must maintain:
|
||||||
|
- Timestamp of analysis
|
||||||
|
- Contract ID
|
||||||
|
- Relevant citations used
|
||||||
|
- User who performed analysis
|
||||||
|
- Any legal opinions provided
|
||||||
|
|
||||||
|
## Legal Disclaimer
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
1. **No Legal Advice**: This corpus is not a substitute for professional legal counsel
|
||||||
|
2. **May Be Amended**: Statutes and regulations change - verify current status
|
||||||
|
3. **Interpretation**: Legal interpretation requires qualified legal professionals
|

4. **Jurisdiction-Specific**: Laws vary by location - ensure applicability
|
||||||
|
5. **Accuracy**: While verified, use official sources for critical decisions
|
||||||
|
6. **Liability Limitation**: Users assume responsibility for verification
|
||||||
|
|
