Enum PolicyScope 

#[non_exhaustive]
pub enum PolicyScope {
    FullSource,
    Observed,
}

What the requirements in a policy are statements about.

A profiler reads what it is given. Whether that supports a claim about the whole source depends on what is being claimed, so the policy says which question it asks rather than letting the evaluator guess.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FullSource

The entire source. A requirement is evaluated only when the evidence covers it, or when the observed data already witnesses a violation that further scanning cannot retract.

Observed

Whatever the metric actually measured — the scanned rows, the retained quality sample, the profiled columns. Always evaluable, and says nothing about the rows that were not read.
