//! `powdb-auth` — argon2id password hashing and a persisted user/role store.
//!
//! Provides PowDB's RBAC primitives: the [`role`] permission lattice, the
//! [`hash`] argon2id password hashing, and the persisted [`store::UserStore`].
//! These are live in production: `powdb-server` loads the [`store::UserStore`]
//! at startup and enforces the [`role`] lattice on every query
//! (`crates/server/src/handler.rs`), and `powdb-cli` manages users via the
//! `useradd`/`passwd`/`userdel` subcommands.
