Compiled worksheet (deterministic artifact)... Application embeds the viewerDesign goals:- deterministic builds - offline computation - finance-safe joins and lookups - Polars-backed table evaluation - explicit lifecycle: commit, build, verify, releaseThe core engine is open source (Apache-2.0) and runs fully locally.Happy to answer questions.
Typical workflow today:

That rewrite step is painful and error-prone and endless.

Design goals:
- deterministic builds - offline computation - finance-safe joins and lookups - Polars-backed table evaluation - explicit lifecycle: commit, build, verify, release
