//! Module: db::schema_evolution
//! Responsibility: schema/data evolution descriptors and migration-plan derivation.
//! Does not own: migration execution, commit durability, or storage layout.
//! Boundary: schema/identity/model inputs -> validated migration plans -> migration engine.
//! This module defines schema/data evolution, derives `MigrationPlan` instances
//! that are executed by `db::migration`, and does not execute migrations itself.
