//! Module: db::executor::authority
//! Responsibility: structural entity authority bundles for executor/runtime boundaries.
//! Does not own: query semantics, store access, or typed API entrypoints.
//! Boundary: replaces ad hoc `E::MODEL` / `E::ENTITY_TAG` / `E::PATH` threading in execution prep.

/// concrete entity type.

/// the entity path from the model itself so execution-core code does not pass
/// duplicated metadata independently.
