aa-gateway 0.0.1-beta.1

//! AAASM-1591 / Epic 18 S-J #1 — end-to-end verification of
//! `GET /api/v1/admin/status` through the real remote-mode router.
//!
//! Boots an in-process Axum listener exposing
//! `aa_gateway::remote_mode::router(Some(backend), database_url)`,
//! exercises the admin_status endpoint with a real SQLite backend, and
//! asserts the documented wire shape (backend / health / latency_ms /
//! row_counts / no timescaledb on sqlite, password redacted when the
//! caller seeds a postgres-style URL).
