FullCoverage: Fraction of CQs whose required elements are fully generated

This metric aims to evaluate the completeness of CQ coverage by computing the fraction of CQs that are answered in full: FullCoverage = |{ i : cov_i = 1 }| / N. A CQ counts only when every required element appears in the generation and is correctly attributed to that CQ.

Example:

N = 4 CQs

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

CQs with cov = 1: {1} → count = 1

Result:

FullCoverage = 1 / 4 = 0.25

What is being measured?

This metric reports completeness, capturing whether each CQ is genuinely satisfied.
