Query Gate - review a plan to give customers live SQL to their data

Check a SaaS product's plan to give customers live SQL to their own data - a warehouse share, a read endpoint or a JDBC/ODBC handle - then write the access blueprint and the customer contract. Free in your browser: the zero-copy share, replicated copy and per-tenant engines ranked by scan economics; every view audited for engine-level isolation, a share-aware identity and a consumer-side probe; the schema checked for a curated mart, an additive-only contract in CI and in-place breaking changes; every compute handle checked for a statement timeout, a concurrency cap and a spend cap; connectivity, credentials and the pricing shape - an isolation probe script and a caps CSV. A metered run writes the access blueprint, or the customer contract with connection pages. Built on the SkillSafe skill @samber/sql-jdbc-access-design, from samber/developer-platform-skills (MIT), by Samuel Berthe.
