This commit introduces a complete transparency infrastructure including: Core Transparency Modules: - AuditLog: Immutable, cryptographically-linked audit trail for all actions - EventStream: Real-time SSE streaming and webhook support - TransparencyDashboard: Aggregated metrics and system health monitoring - DigitalSignatures: Cryptographic verification for handoffs and certificates API Endpoints: - /api/transparency/dashboard - Full platform metrics - /api/transparency/audit - Query and log audit entries - /api/transparency/events - SSE stream and event history - /api/transparency/webhooks - Webhook management - /api/transparency/signatures - Digital signature operations - /api/transparency/certificate/[plantId] - Plant authenticity certificates - /api/transparency/export - Multi-format data export - /api/transparency/report - Compliance reporting - /api/transparency/health - System health checks Features: - Immutable audit logging with chain integrity verification - Real-time event streaming via Server-Sent Events - Webhook support with HMAC signature verification - Digital signatures for transport handoffs and ownership transfers - Certificate of Authenticity generation for plants - Multi-format data export (JSON, CSV, summary) - Public transparency portal at /transparency - System health monitoring for all components Documentation: - Comprehensive TRANSPARENCY.md guide with API examples
