Axeyum encoded the dependencies and candidate decompositions, then checked lossless join and dependency preservation as separate properties.

Recorded result
The street, city, and ZIP-code example has a lossless BCNF repair that cannot enforce its original dependency locally.
Supporting artifacts
Artifact pages contain the formal statement, proof route, evidence, provenance, and direct dependency graph recorded in the ledger.
- The BCNF repair of the street/city/zip schema rejoins exactly and cannot enforce its own dependency; two other splits lose information search-certificate · F:bcnf-decomposition-lossless-not-dependency-preserving
