PSSU: The Minimal Architecture for Persistent AI

Persistent Stateful Self-Update — The Core of PermaMind By Nile Green — PermaMind Research Series 🌱 Overview PSSU (Persistent Stateful Self-Update) is the minimal architecture required to build an AI agent that: maintains identity across sessions remembers permanently evolves based on experience resists drift and collapse grows more coherent over time It is the core runtime behind PermaMind, the first open framework for persistent AI. Traditional agents reset. PSSU agents survive. 🔧 Why PSSU Exists Most AI systems today are stateless loops: prompt → response → reset Even "memory" systems are usually: external brittle unbounded not part of the agent's self This prevents: identity formation long-term pattern accumulation compounding intelligence stable behavior PSSU solves this by giving an agent bounded, permanent write access to its own internal state. 🧠 The Four Pillars of PSSU 1. Persistent Identity The agent's identity survives across sessions, tasks, environments, and restarts.
