//! Bad `query` **attributes and names** (cratestack#867): unrecognised
//! attributes, colliding names, and a query in a schema that configures no
//! database.
//!
//! The unrecognised-attribute case is the one worth not dropping: without
//! it, a misspelled `@alow` would parse silently and leave the query
//! deny-by-default with nothing to explain why.
//!
//! Everything about the *SQL body itself* — missing, duplicated,
//! malformed, or needing escapes — lives in
//! [`tests_queries_sql_body`](crate::tests_queries_sql_body), which is
//! also where the `view` half of those shared rules is checked.
//! Signature-level rejections live in
//! [`tests_queries_rejections`](crate::tests_queries_rejections).
