S2-H09 Complete: Document Tracking & Versioning System Specification
Comprehensive design for document versioning with IF.TTT compliance:
- Git-style versioning (create, update, rollback, history)
- IF.TTT implementation (Ed25519 signatures, SHA-256 hashing, ISO 8601 timestamps)
- Database schema (documents, document_versions, access_control, audit_log)
- 8 RESTful API endpoints (upload, versions, download, verify, rollback, compare, search, delete)
- Meilisearch integration with OCR support (Tesseract.js for PDFs/images)
- Mobile-first UI (upload flow, version history timeline, diff viewer, signature verification)
- Security: signature verification, access control, encryption at rest/transit, audit logging
- IF.bus integration: WhatsApp notifications for document uploads
- Implementation roadmap (8-week phased approach)
