# Dependencies and originality

The viewer, geometry, studio, schema, export code and synthetic Harbor Works diagram were authored independently for Nishvault. No competitor source, product files, visual assets, marks or purchased package was used. The frozen customer job was the starting point; no claim of competitor feature parity is made.
