openhuman/tests/memory_tree_sync_raw_coverage_e2e.rs

//! Focused raw integration coverage for memory-tree and memory-sync modules.
//!
//! This suite is intentionally hermetic: every test uses a temp workspace and
//! any provider behavior is supplied by small in-process stubs. Run with
//! `--test-threads=1` because config/env and a few registries are global.
