Ori-Mnemos vs matryca-plumber

Ori-Mnemos: Ori Mnemos is an open-source persistent memory infrastructure for AI agents that implements human cognition models on a knowledge graph. It uses ACT-R decay, spreading activation, and Hebbian learning to manage memory, and achieves state-of-the-art retrieval performance while being zero-infrastructure and portable.; matryca-plumber: Matryca is a headless MCP server and CLI that turns a local Logseq graph into an agentic workspace. It operates without network APIs or background desktop app, using atomic AST writes and X-Ray token compression. It provides spatial intelligence, sandboxed privacy, and zero-database lexical engine.
