Interface CreateOfflineRegionDiagnosticOptions

Logical payload-byte ceiling used to explain admission and eviction.

Explicit clock input so persisted diagnostics are reproducible.

Age at which the snapshot observation becomes stale.

Optional storage-budget observation from probeOfflineStorageBudget(). Persisted state changes the eviction risk of every cached region, so it is reported here rather than inferred. The diagnostic never probes on its own.
