A reader can study the seven dimensions and the five tiers and still not know what a score of 58 means, what evidence produces a 4 rather than a 7, or why two deployments with the same total can land in different tiers. Scoring a real, named AI product would have been easy, and the exercise would have been invalid.
Read what the dimensions ask for: a documented blast radius per tool, a named individual with written authority to halt the agent, a retained run history with dates and versions, per caller spend caps, an audit trail that keeps the originating identity across a service boundary. None of that can be observed from outside for any third party system. A vendor's public documentation describes what a product can do, never what a deployer's evidence file contains. A score built on absent evidence would measure how much a company chooses to publish, dressed in the apparatus of a real assessment.
It would also be a reputational claim about a company that never asked for one, made by a party with no relationship to it, and the words "illustrative only" do not survive being quoted by a search engine or an assistant three steps downstream. So the deployment is constructed. Nothing empirical is asserted about anyone, and every number comes from the published rubric, which means the arithmetic can be checked instead of trusted.
