# quatzal-query — Query layer
Query composition over Quatzal's vector and graph indexes.
**Linux only** (depends on the storage engine).
Part of [**Quatzal**](https://github.com/logixrcorp/quatzal), a local-first vector + graph
database that records who vouched for every fact and when it stopped being true.
## Status
Pre-release (0.1.0). Data formats are not yet stable: old snapshot files are deliberately
unreadable rather than silently misread, and there are no compatibility shims. Treat a store
as reproducible from its source data, not as an archive.
## License
Apache-2.0. Quatzal is open core — the Apache-2.0 core is the whole of this crate; separately
licensed commercial modules live outside published packages.
