Score: 6.8/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 5)

Oraculum is an incremental SQL parser and enforcer that guarantees grammatical and semantic correctness using token-level automata, lazy determinization of a grammar NFA, and a latent state layer that tracks schema constraints. It includes a WASM playground and supports a well-defined SQL subset, making it interesting for developers interested in parsing, formal language theory, or SQL tooling.

Target audience: backend devs, data engineers, language tooling enthusiasts
