# CertScroll

> CertScroll is an open knowledge graph, offline-capable assessment engine, and Model Context Protocol (MCP) portal for 10 overlapping AI and Cloud certifications by Wanessa Labs.

## Core Purpose & Pedagogical Architecture

CertScroll maps 10 major artificial intelligence and cloud certifications into a unified knowledge graph. Rather than studying disjointed vendor syllabi in silos, CertScroll organizes learning into shared conceptual foundations across 4 cognitive tiers:
1. **Recall & Recognition:** Core definitions, terminology, and component identification.
2. **Mechanics & Workflow:** Architectural pipelines, training dynamics, parameter tuning, and deployment.
3. **Comparative Analysis & Trade-offs:** Cost vs latency, fine-tuning vs RAG, model quantization, and vendor service mappings.
4. **Production Scenarios & Edge Cases:** Real-world failure modes, security best practices, and ethical governance.
