+//! Physical operators for a small query-plan executor.
+//!
+//! Targeted scope:
+//! - atom scans with repeated-variable filtering and variable-binding output
+//! - semijoins
+//! - natural joins
+//!
+//! The operators are intended to be composed by hand into a small plan and
+//! evaluated against in-memory relations. Integration with an external query
+//! plan IR is out of scope for this crate.
