 ## Licensing
 
-- **Source content:** Python Software Foundation License — all retrieved passages retain upstream licensing. Attribution to the upstream repo is required for redistribution.
-- **Knowledge model artifact** (field + registry + metadata): [Business Source License 1.1](https://mariadb.com/bsl11/) — same license as the [Resonance Lattice project](https://github.com/tenfingerseddy/resonance-lattice-cli).
+### Source content
+
+This knowledge model indexes (and in the **bundled** variant, redistributes) content from **[python/cpython](https://github.com/python/cpython)**.
+
+- **Copyright:** © Python Software Foundation. All rights reserved.
+- **License:** [Python Software Foundation License Agreement](https://docs.python.org/3/license.html)
+- **Modifications:** Source files are chunked into retrieval-sized passages and indexed into a semantic field + registry. In the **bundled** variant, the source files themselves are packed unchanged as zstd frames inside the `.rlat` (lossless; re-chunking at query time produces the same bytes as the upstream file at the pinned SHA). In the **remote** variant, no source content is redistributed — queries fetch directly from the upstream repo on first access.
+
+All retrieved passages retain their upstream license. Commercial use is permitted under the upstream license; attribution to the upstream repo is required when redistributing passages.
+
+### Artifact structure
+
+The knowledge-model *structure* — semantic field tensor, source registry, manifest, encoder configuration — is licensed under the [Business Source License 1.1](https://mariadb.com/bsl11/), the same license as the [Resonance Lattice project](https://github.com/tenfingerseddy/resonance-lattice-cli). Each release converts to MPL 2.0 four years after it's first published.
+
+BSL 1.1 applies to the *structure* of the knowledge model (how it indexes and retrieves), not to the embedded content. You can use this rlat commercially for retrieval and grounded AI workflows over the indexed docs; what BSL restricts is building a competing Resonance Lattice implementation from the lattice structure itself. See the [BSL 1.1 plain-language summary](https://github.com/tenfingerseddy/resonance-lattice-cli/blob/main/docs/LICENSE_FAQ.md).
