 ## Project Structure & Module Organization
 - `crates/lance-graph/` hosts the Rust Cypher engine; keep new modules under `src/` and co-locate helpers inside `query/` or feature-specific submodules.
+- `crates/lance-graph-catalog/` provides catalog and namespace utilities, including Unity Catalog and Delta Lake integration; feature-gated via `unity-catalog`.
+- `crates/lance-graph-benches/` contains performance benchmarks in a dedicated unpublished crate; add new benchmarks here rather than in the main crate.
 - `crates/lance-graph-python/src/` contains the PyO3 bridge; `python/python/lance_graph/` holds the pure-Python facade and packaging metadata.
 - `python/python/tests/` stores functional tests; mirror new features with targeted cases here and in the corresponding Rust module.
 - `examples/` demonstrates Cypher usage; update or add examples when introducing new public APIs.
 
 ## Build, Test, and Development Commands
 - `cargo check` / `cargo test --all` (run inside `crates/lance-graph`) validate Rust code paths.
-- `cargo bench --bench graph_execution` measures performance-critical changes; include shortened runs with `--warm-up-time 1`.
+- `cargo bench --bench graph_execution -p lance-graph-benches` measures performance-critical changes; include shortened runs with `--warm-up-time 1`.
 - `uv venv --python 3.11 .venv` and `uv pip install -e '.[tests]'` bootstrap the Python workspace.
 - `maturin develop` rebuilds the extension after Rust edits; `pytest python/python/tests/ -v` exercises Python bindings.
 - `make lint` (in `python/`) runs `ruff`, formatting checks, and `pyright`.
