//! `AccessControlRepository` — sqlx-backed access to the two-table authz
//! schema.
//!
//! `access_control_entities` owns one row per `(entity_type, entity_id)` and
//! carries the `default_included` flag plus a `source` provenance string.
//! `access_control_rules` is the per-(entity, subject) grant table, with a
//! foreign key back to the entity catalog. Callers fetch the entity row
//! first (a `None` result signals an entity unknown to access control), then
//! list rules for it, and hand both to [`super::resolver::resolve`].
