Synthetic catalog preflight demo — not client work.
Arratz uses AI-assisted development and deterministic checks to make catalog changes traceable. This local 12-row example flags 9 rows with errors and proposes only 2 formatting changes. Duplicate IDs remain preserved; ambiguous prices and missing identifiers are never invented.
The 11-test safeguard suite passed again on 22 September 2026. These are limited local checks, not a Google submission, acceptance guarantee or client result. Source files, before/after changes and unresolved exceptions remain separate.
