Added 2026-10-08: S3 candidate; per-CVE honeypot exploitation telemetry pages (first and last observed dates, attempt counts, KEV status) that `extract` reads cleanly and that are live-updated, so the page's own date metadata is stale. Cited in a published update on the Atlassian flaw as the exploitation cross-check. Reliability C until a track record exists.
