How does Burna AI handle protocols where the trial drug profile is sensitive sponsor IP?

Through Protocol Safe, a sponsor-tenant architecture where the trial protocol stays inside the pharma sponsor's own cloud infrastructure. A retrieval agent ingests the protocol behind the sponsor's boundary and is queried for the trial drug's expected adverse event profile. Content boundary middleware fail-closes against any response that is not a structured probability score. Only the attribution signal crosses the boundary. The protocol never leaves the sponsor's vault.
