EKOS compiles heterogeneous enterprise sources — code, SQL schemas, ETL pipelines, git history, CI/CD, GitHub issues, Confluence, docs — into a single append-only, evidence-backed ledger. Every fact traces back to where it came from. Conflicts between sources are surfaced with citations, not silently resolved. When EKOS doesn't know something, it says "unknown" instead of guessing. Open source, Rust-based — built for teams tired of AI tools that answer confidently and wrongly.
