Add complete Traceable, Transparent, Trustworthy framework for ContractGuard legal service compliance, ensuring every legal document can be traced to authoritative source with cryptographic verification. Core IF.TTT Components: * Traceable: Unique if://citation/[uuid] identifiers with git commit references * Transparent: Full audit trail in PROVENANCE_CHAIN.md with chain of custody * Trustworthy: SHA-256 verification, automated validation, 100% verification status Implementation: - Add legal citation schema v1.0 with all required metadata fields - Generate citations for all 59 existing documents in corpus - Create comprehensive PROVENANCE_CHAIN.md audit trail - Add citation validation tool with 8-point integrity checks - Enhance Chroma ingestion to preserve citation metadata - Update README with IF.TTT compliance documentation Verification Results: - Total Citations Generated: 59 - Verification Status: 59/59 PASSED (100%) - Jurisdictions Covered: UK, US, CA, AU, DE, EU, INT - Document Types: statutes, regulations, datasets, industry standards Legal Service Requirements Met: - All documents sourced from authoritative government repositories - Complete hash verification and file integrity checks - Provenance chain documents download → validation → ingestion - Citation metadata embedded in Chroma for RAG queries - Legal disclaimers and verification timestamps preserved Files Added: - schemas/legal-citation-v1.0.json: JSON schema specification - citations/legal-corpus-citations-2025-11-28.json: 59 citation records - audit/PROVENANCE_CHAIN.md: Complete chain of custody (1200+ lines) - audit/validation-report-2025-11-28.json: Automated verification report - tools/generate_citations.py: Python script to generate citations - tools/validate_legal_citations.py: Citation validation tool Files Modified: - README.md: Added IF.TTT Compliance section with usage documentation - scripts/ingest_chromadb.py: Enhanced to load and preserve citation metadata This framework ensures ContractGuard can demonstrate full legal compliance, provide verifiable source attribution, and support secure contract analysis.
