SQL-aware comment removal with literal preservation

Use the SQL already entered above, but make the removal policy explicit. Choose line/block comments independently, preserve optimizer hints when needed, and optionally keep newline positions so diagnostics and line numbers stay comparable.

Token class	Count	Policy	Safety evidence

The scanner treats single/double/backtick quoted text as data and does not strip comment-looking text inside those literals. Dialect-specific quoting beyond these forms still deserves review before execution.

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.
