When validate_schema=True, convert()/convert_parameterized()/analyze() raise InvalidSchemaError for unrecognized table or field references in table.field expressions. This catches typos and references to nonexistent fields that would otherwise silently produce incorrect SQL. Validation skips comprehension variables, bare identifiers, and nested JSON keys beyond the first field. Requires schemas to be provided. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
