• Bosko/ Kevin: Update the Risk Register to include:

  • Plutus cost model changes negatively affecting existing DApps.

  • CC dropping below 7 members before CommitteeMinSize reduction.

• Bosko: Finalize the Stakeholder Contact Map and delegate outreach for DApps (Leonard) and Exchanges (Cardano Foundation) to ensure they are testing against v10.7.1.

• Kevin / Ryan Williams: Finalize the metadata and chaining logic for the CommitteeMinSize governance action following the enactment of the cost models on Preview.

• Bosko: Refine the X Space / Community Engagement strategy to target specific stakeholder groups (e.g., a session specifically for SPOs or DApp/DEX developers) to increase participation.

• Bosko: Finalize the background list of all ecosystem stakeholders and contact points to ensure targeted communications for the v11.0 upgrade.

• Bosko: Finalize the open Discord HF channel permissions to allow public "read-only" access for non-Intersect members by next week.

• Ryan Williams: Share the Builderfest recording on technical short-listing once available to incorporate broader community feedback into the Dijkstra scoping process.
