  scope_statement: 'This service publishes verdicts about other people''s servers. If a verdict here is wrong, that is a security problem, not a support ticket. Send the endpoint, what you measured, and from where. A report that contradicts our own measurement is the most useful kind, and it will be published either way.'

bug_bounty: null
disclosure_page: null
notes: >-
  Two RFC 9116 files with Contact and Policy lines and a stated scope of what counts as a vulnerability; the gate
  copy lacks the mandatory Expires field and its Policy target is the register page rather than a disclosure policy.
  No HackerOne / Bugcrowd / Intigriti programme and no dedicated disclosure page were found. The repository carries
  an ops/security_audit_20260913.md and a .gitleaks.toml, which suggest an internal practice but are not a public
  programme. The probe-security-programs.py script could not find these because it probes the registrable domain,
  which does not resolve.
