//! Module: lib
//! Responsibility: crate root for the IcyDB core runtime surface.
//! Does not own: canister-facing facade APIs from the public `icydb` crate.
//! Boundary: exposes the engine subsystems used by schema, query, executor, and storage layers.

//! Core runtime for IcyDB: entity traits, values, executors, visitors, and
//! the ergonomics exported via the `prelude`.
#![warn(unreachable_pub)] // too complex to adhere to right now
