  Empty signals, measured. OPC / 彼岸花开 is a one-person company whose entire public surface is a
  consumer chat app at the site root (彼岸花开 · 花灵, login-gated), the /lei/ service page for the
  on-site video service, and the A2A card + JSON-RPC endpoint. It publishes no accessibility
  conformance report, no subprocessor list, no DPA, no privacy policy or terms page at any
  conventional path, no data-subject-request page, no transparency report, no SBOM, no
  support-lifetime statement, no data-residency statement and no AI-transparency page. The /lei/
  page does state in prose that "Replies are written by an AI trained by Lei himself. Lei reviews
  the chat history regularly." - an in-page AI disclosure, recorded below as observed but NOT
  mapped onto ai_transparency, because it is a sentence on a marketing page rather than a
  transparency document (the known false-positive path). No regime is inferred here.
