It provides cubes, weighted consolidations, a rules-and-feeds calculation engine, MDX, TypeScript \"flows\" for ETL, what-if sandboxes, and a fast pivot grid with write-back.\n\n\u003e **Status: Phase 1 (in progress).** Greenfield and under active construction. See the [roadmap](docs/ROADMAP.md).\n\n## What makes it different\n- **Model-as-code:** the whole model is human-readable, Git-versionable text.\n- **TypeScript flows** for ETL and automation, instead of a proprietary scripting language.\n- **Automatic feeder inference** and **calculation provenance**, so you can ask why a cell holds the value it does.\n- Three hard requirements shape the design: it stays deterministic and directly testable, it is fast and memory-efficient, and it stays simple for the people who use it.\n\n## Quickstart\nPrerequisites: Rust (stable) and Node (the version in [`.node-version`](.node-version)).\n\n```sh\n# Rust engine (from the repo root)\ncargo test --workspace\ncargo run -p epiphany-server\n\n# Web client\ncd web\nnpm ci\nnpm run dev\n```\n\n## Layout and docs\n- Architecture, conventions, and commands: [AGENTS.md](AGENTS.md)\n- Plan of record: [docs/ROADMAP.md](docs/ROADMAP.md)\n- Architecture decisions: [docs/adr/](docs/adr/)\n- Engineering practices: [docs/agentic_ai_programming_best_practices.md](docs/agentic_ai_programming_best_practices.md)\n\n## License\nLicensed under the [MIT License](LICENSE).
