Engram Agentic System Maturity Assessment Executive Summary This document provides a comprehensive maturity assessment of the Engram system against the **Seven Layers of Production-Grade Agentic Systems** framework. Using a 5-star rating system, we evaluate each layer and subsection, identify gaps, and provide a clear path forward to full production-grade maturity.

Overall System Maturity: ⭐⭐⭐☆☆ (3.0/5.0)

The Engram system demonstrates a solid foundation with key components implemented across all seven layers. Notable strengths include the Temporal-based durable execution, Zep memory integration, MCP protocol implementation, and OpenTelemetry observability. However, significant gaps exist in guardrails, advanced reasoning patterns, and evaluation frameworks that must be addressed for full enterprise-grade maturity.
