Measured-censorship profile for one country (national blocks under review)

Under review: while the block-verdict review is on, this route answers HTTP 200 with every verdict field set to unknown or null (some coverage fields may remain), a top-level review object (status under_review, verdict unknown, reason, source, and dataAsOf: the data date, or null when the source reports none or could not be read) and X-Voidly-Verdict-Review: under_review, with Cache-Control no-store. A held answer is not an outage and not a finding either way; see https://voidly.ai/data-quality#block-verdict-review. Freshness (last measurement and band), 30-day volume and the censorship-technique mix remain; nationally_blocked_domains is null while held. For the composite data-confidence score see /v1/measurement/quality; for citable events see /data/incidents. When not held, 404 if no measurements are on record; while held, an unmeasured or unknown code answers 200 with measured, freshness, volume and techniques null.
