# Open Source Attribution Notices These entries identify upstream material used by Promptkit. The [OSS policy](../policy/oss.md) owns the format and maintenance rules; the [project grant](../../COPYRIGHT) does not replace third-party terms. The module entries cover the five external modules used by `go list -deps -test ./...` at adoption, including the transitive `golang.org/x/text` dependency. Other modules present only in dependency module graphs are not thereby incorporated into Promptkit. No separately copied third-party code or asset notices were identified in Promptkit's source; adapted policy documents are attributed separately below. Standard license texts in `licenses/` are shared reference texts, not additional project grants. ## Promptkit OpenRouter Catalog Selected module: `gitea.maximumdirect.net/eric/promptkit-backend-openrouter/v2` at `v2.20260926.0`.
