rewards:

    per-report bounty tables were not readable from a non-authenticated fetch.

scope: system vulnerabilities, IoT, mobile applications, industrial control systems,
  AI security, large-language-model security
safe_harbour_published: unknown

security_txt:
  served: false
  note: No RFC 9116 /.well-known/security.txt on any QAX host — see well-known/qi-anxin-well-known.yml.
    The disclosure route is a web platform, not a machine-discoverable security.txt.
third_party_bounty_platforms:
  hackerone: not found
  bugcrowd: not found
  intigriti: not found
  note: QAX runs its own platform rather than using a Western bounty host, which is
    why the automated probe (probe-security-programs.py, which looks for security.txt
    plus HackerOne/Bugcrowd/Intigriti) returned vdp=none. Recorded here by manual search.
