a Python framework that builds a semantic, graph-based reasoning layer over enterprise data — where data lives, what it means, its lineage — reconciles conflicting definitions across systems, validates agent-generated queries against certified definitions, and serves that context to any agent harness via MCP, CLI, or API. The AlphaSignal headline ("stops agents from returning wrong data") overstates it; the repo itself frames it as deterministic query generation and provenance with every answer.
