openhuman/tests/memory_raw_coverage_e2e.rs

//! Focused raw integration coverage for memory-family modules.
//!
//! These tests avoid network and keep all state in per-test tempdirs. Run with
//! `--test-threads=1` because several memory surfaces use process-global
//! stores or cached SQLite connections.
