-* [Sponsor Communication and Engagement](sponsor-communication-and-engagement.md): the case studies this pattern surfaces are a direct input to the sponsor readouts described in that pattern, giving sponsors concrete, specific evidence of the program's impact rather than only aggregate metrics.
+* Sponsor Communication and Engagement (proposed in [PR #931](https://github.com/InnerSourceCommons/InnerSourcePatterns/pull/931), pending review): the case studies this pattern surfaces are a direct input to the sponsor readouts described in that pattern, giving sponsors concrete, specific evidence of the program's impact rather than only aggregate metrics.
 * [Sponsor-Amplified Evangelism](sponsor-amplified-evangelism.md): confirmed success stories from this pattern are exactly the kind of concrete material that makes a sponsor's cue, and the broader evangelism effort, credible and specific rather than generic.
 * [Introducing Metrics in InnerSource](https://github.com/InnerSourceCommons/InnerSourcePatterns/blob/main/patterns/1-initial/introducing-metrics-in-innersource.md): addresses the broader need for concrete metrics to justify and understand an InnerSource program. This pattern is a specific, applied technique for generating one particularly persuasive kind of evidence, individual, confirmed collaboration stories, rather than aggregate statistics alone.
 * [Repository Activity Score](https://github.com/InnerSourceCommons/InnerSourcePatterns/blob/main/patterns/2-structured/repository-activity-score.md): provides a numeric measure of a repository's overall activity. This pattern is a complementary, more targeted technique aimed specifically at detecting cross-team activity rather than activity in general.
