+## Use Cases (Moncef)
+
+- **Status:** Use cases have been translated into English and are available on a dedicated branch: [`OKDP/docs/use-cases`](https://github.com/OKDP/OKDP/tree/docs/use-cases/use-cases).
+- **Feedback:** A community discussion is live : [discussions:10](https://github.com/orgs/OKDP/discussions/10).
+    - **Adaltas** noted that documentation and tooling components are currently missing. Octave will open a Pull Request (PR) to address these gaps.
+- **Strategic Note:** Use cases serve as focus areas for contributors rather than a formal roadmap. The **TOSIT members** will finalize the roadmap at a later date.
+- **Priority:** **DGFiP** will prioritize documentation and Helm charts in the immediate term.
+
+## Control-Plane Iteration Demo (Moncef)
+
+Moncef demonstrated the latest iteration of the OKDP control-plane (rebranding of [`okdp-server`](https://github.com/OKDP/okdp-server) and [`okdp-ui`](https://github.com/OKDP/okdp-ui)).
+
+- **Tech Stack:** Built on **Flux**, **KuboCD**, and **KubeAuth**.
+- **Operational Components Included:** JupyterHub, Spark History, and Spark Application.
+- **Status:** Repositories have been moved to the OKDP organization but remain **private** for the time being.
+
+## Future Repository Organization (Jean-Pascal)
+
+Jean-Pascal presented a proposal for restructuring the OKDP repositories.
+
+- **Reference:** The proposed architecture can be viewed via this [Excalidraw schema](https://excalidraw.com/#json=5BAjpLnPWf-t9gABHWcb2,HCVgwAzqdVgz341sqhXsgQ).
+- **Next Steps:** A PR will be submitted to implement this structure prior to the next session.
+
+## OPA/OPAL Technical Presentation (Stephan)
+
+Stephan concluded the technical deep dive into OPA/OPAL started in the previous meeting. New Repositories include :
+
+- [`opal-fetcher-postgres`](https://github.com/OKDP/opal-fetcher-postgres): A fork utilizing `branch-0.9.4` as the default. This branch includes specific adaptations (similar to the historical TDP approach).
+- [`trino-opal-example-policy`](https://github.com/OKDP/trino-opal-example-policy): Dedicated repository for policy management.
+- [`opa-trino`](https://github.com/OKDP/opa-trino): Currently **private** pending a final naming decision.
+
+## Additional Comments
+
+- **Review Process:** Paul requested that all discussions regarding code or documentation contributions be centered around **open PRs** rather than live screen-sharing of local environments. This mirrors the workflow used in TDP meetings, ensuring all contributors have access to the source material for peer review and transparency.
