Lite, local-first code+context graph: recall + impact over SQLite/FTS5 with ACT-R activation, tree-sitter + ripgrep edges, embeddings opt-in.

CodeGraphX is a local, token-efficient indexing engine that maps codebase dependencies for AI agents. By storing data in a high-density TOON format and serving it via MCP, it eliminates expensive file re-scanning and cuts token usage. It features O(1) symbol lookups and a real-time dashboard, agent with persistent, low-latency architectural context
