Nexus 3.0 is an AI Memory & Coordination Platform built on Redis with a dual-pod architecture (vault/operational). This KB documents the core systems, shared modules, and patterns used across all MCP servers.
Core Concepts
- Stable User IDs: u_XXXX format (4 alphanumeric chars) for multi-tenant support
- Session IDs: s_XXXX format derived from session suffix
- Dual-Pod Pattern: Even ports = vault (write), Odd ports = operational (read)
- Quadfecta Search: 4-layer scoring (keyword, vector, graph, temporal)
