Licenses & Dependencies — Digital Partner

Acknowledgments. This project would not have been possible without the decisive contribution of the free and open-source software listed below — foundational, shared by their authors with everyone. We express our deepest gratitude to them. We also thank Agent Zero, the intelligent assistant that supported the design and development of this project.

The product's own code remains deliberately closed: we have chosen to keep control of its evolution in the face of possible undesired uses. The dependencies themselves remain open source and compliant with their respective licenses.

Digital Partner relies on an ecosystem of open-source components. This page lists dependencies, their respective licenses, and how they are used in the project. It serves as a compliance register for license audits.

5. Real-time Usage Reporting

A live dependency-usage reporting system is being deployed. It will track:

Which module uses which dependency
Call volume per dependency (daily/monthly)
Alert thresholds for licenses with revenue clauses (e.g. Stable Diffusion > $1M)
Export for compliance audits

Beta license module — extension planned for version 4.0.
