NOVA // Ygdrassil

NOVA // Ygdrassil — a multi-model AI ecosystem where specialised agents collaborate over shared memory, coordinate work on isolated branches, and every merge is gated by human approval. DESCRIPTION: NOVA // Ygdrassil (META Edition) connects specialised AI models, agents, shared project context and human participants in one collaborative environment. Built on Muse Spark for the Meta Global AI Developer Hackathon 2026, it asks a practical question: how can different AI capabilities work together on a real task, share relevant context, expose their limits — and keep every consequential decision under human control? The system has three pillars. Multi-Agent Bus Chat: selected agents answer in parallel from a shared, content-indexed project memory, with honest status lamps (gray = idle, green = live reply, red = provider error). Workflow Manager: chains agents into ordered task graphs on isolated git branches — one writer per task, inspectable at every step. Human Authority: an external approval node (plus a separate portal) where a human releases or rejects each result with YES / NO / INFO before anything merges. The stack is deliberately local-first: a browser-based V6 workspace, a small Node.js bridge with a token-guarded HTTP API, parallel memory-aware requests to six model providers, and a Muse Spark connector prototype using the Model Context Protocol (MCP). The Ygdrassil world-tree metaphor maps directly onto the architecture — roots (memory), trunk (shared context), branches (models and agents), gardener (the human who approves). NOVA is dedicated to Hüseyin Gür — 50 years as a welder in Germany. Fire, steel, and hands that build things to last. Live demo, demo video (6:24), and full source below.
