Before running the SQL

The SQL layer keeps transformation, generation, and inspection in the browser. Existing /SQL engines remain intact while the new inspector adds statement, table/CTE, placeholder, clause, and bounded structural-warning context.

Parser and execution boundary

WebToolArc does not connect to a database or execute these statements. The shared scanner handles common lexical structures, quoted strings/identifiers, comments, parameters, and practical references, but it is not a vendor-complete grammar, schema validator, optimizer, lineage engine, or security review. Use a real database/parser when those guarantees matter.
