    dcterms:description """
This metric aims to evaluate the breadth of CQ coverage by computing the fraction of competency questions for which the generation includes at least one required element. With cov_i is the individual CQ coverage rate and N the number of CQs: AtLeastOneCoverage = |{ i : cov_i > 0 }| / N.

**Example:**

N = 4 CQs

CQ coverage rates cov: [1.0, 0.5, 0.0, 0.7]

CQs with cov > 0: {1, 2, 4}    → count = 3

Result:

AtLeastOneCoverage = 3 / 4 = 0.75

**What is being measured?**

This metric reports whether the model engages with every CQ at all. A CQ left entirely unanswered fails this measure, even when others are fully covered. It is reported under both the term-level CQ2Term coverage and the axiom-level CQ2Onto coverage.
