Enum PageResidencyOutcome 

pub enum PageResidencyOutcome {
    Measured {
        resident_pages: usize,
        total_pages: usize,
    },
    Unsupported,
    Failed(String),
}

An observed residency count for one section at a policy boundary.

This records a measurement for the OQ-18 access-class evidence, not a contract with the kernel: page-cache state can change immediately after mincore returns, and a failed observation must never reject an otherwise valid artifact.

Variants

Measured

The kernel reported the number of resident pages in the section’s range.

Fields

resident_pages: usize

Pages resident at the observation point.

total_pages: usize

Pages spanned by this section.

Unsupported

This build has no audited residency-query implementation.

Failed(String)

The OS rejected the observation; artifact integrity is unaffected.
