Negative control example.com fresh scan: 'No AI builder evidence found', 33 fingerprints across 9 builders checked, no builder named, only Cloudflare CDN detected. Second Base44 site ironsighterp.info: fresh scan failed (see breaks); its cached Oct 10 2026 report (viewed without new scan) shows Base44 Confirmed with the same two signal types. Base44 category page lists 2 indexed Base44 sites (villadoimperio.com, ironsighterp.info).",
  "breaks": "1) Fresh scan of ironsighterp.info (/site/ironsighterp.info/?fresh=1) returned 'Scan failed: A secure (TLS) connection could not be established with this website.' Not retried because of the 3-scan cap. Whether the cause is the target site or the checker is unverified. 2) Default form submit returns the cached report ('Cached Oct 14, 2026') rather than a new scan; fresh results need ?fresh=1 or Re-scan. 3) Fresh-scan reports omit the Re-scan button (confirmed again: page text shows Scanned, Copy, Export, with no Re-scan; cached reports show it). 4) No Strong evidence tier observed in any of the 3 scans today; the Base44 template signal (default page title) was not seen on either site.",
