The project maintainer runs automated checks on all artifacts covered by a change being pushed or a pull request, (unit tests, lint, integrity and security checks among them), and each request a developer makes to a repository is consistent with that developer's assigned role (for example application updater or package manager). The platform that performs these operations is itself hardened, isolated and secure.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
