KeiSeiKit-1.0/_primitives/_rust/kei-discover/tests/smoke.rs

//! Integration smoke tests for the kei-discover public API.
//!
//! Covers the 6 behaviours enumerated in task.toml:
//!   1. register returns id + increments count
//!   2. list_available excludes installed
//!   3. mark_installed flips flag
//!   4. search matches slug and description via FTS
//!   5. register rejects duplicate slug
//!   6. stats counts
//!
//! All tests use `open_memory()` so they neither touch nor contend with
//! the on-disk default DB path.
