# Third-party notices and exclusions

The repository's CC BY 4.0 grant applies only to material Shawn Wang controls. The table below is generated from `assets/rights.json` and `assets/clearance.json`. Shawn Wang attested that all retained assets were cleared for the 2020 publication and for redistribution in this public source repository and its outputs. That permission closes the redistribution gate but is not represented as a CC BY sublicense; third-party works retain their recorded licenses or rights.

## Contributor text

- **Foreword:** Quincy Larson's foreword is publisher-attested as cleared for inclusion and CC BY 4.0 publication in this open edition.
- **Nat Sharpe editing:** Nat Sharpe's interwoven editorial contributions are publisher-attested as cleared for CC BY 4.0 publication in this open edition. Git blame remains provenance, not a claim of sole authorship.

## License compatibility notes

CC BY-SA works retain their ShareAlike requirements for adaptations. The xkcd image remains CC BY-NC 2.5; the publisher attests separate publication permission, while downstream commercial reuse still requires compliance with the applicable permission or a separate grant. MIT and ISC components retain their upstream copyright and license notices at the linked sources; this record does not replace any notice required in a distributed adaptation.
