July 2025 monthly summary for google/android-cuttlefish: Delivered Vsock Proxy for Root Canal to enable link-layer traffic, including port-forwarding configurations for both the standard link-layer port and the link-layer BLE port to a vsock server. This work establishes robust communication channels for link-layer data within Root Canal, enabling integrated testing and higher-fidelity simulations. Key commit: 9f59f60d10a29a89c54adb4f87db9c4c9817821c. No major bugs fixed this month. Impact: improved testability, data-path isolation, and end-to-end validation of the vsock-based link-layer pathway. Technologies/skills demonstrated: vsock proxy integration, port-forwarding configuration, Root Canal data-path wiring, commit traceability and code review.
