//! The named fields' own tables: the four `seen` watermarks (record, gate by
//! oid, coerce a wrong-typed slot, all-at-once, and the phantom that
//! materializes nothing), the pin list and the collapse overrides. The file
//! mechanics they end on — forgiving load, echo/adopt, the atomic write — are
//! `super::super`'s.
