  "message": "[SM] CL 1/n: Refactor BlindSignAuth to accept generic attestation data\n\n- Refactor BlindSignAuth to accept `google::protobuf::Any` for attestation data to enable cross-platform compatibility.\n\n- By replacing the `absl::Span\u003cconst std::string\u003e` parameter (which was previously used to pass Android-specific attestation certificates) with a generic `Any` protobuf, we decouple the core QUICHE library from platform-specific attestation structures. The responsibility of constructing the platform-specific proto (e.g., `AndroidAttestationData` for Android or `IosAttestationData` for Apple devices) is now correctly delegated to the platform-specific callers (like the Android JNI layer).\n\n- It was chosen to refactor the interface rather than introducing method overloads (i.e. maintaining the old Android signature alongside a new iOS signature) to keep the core `BlindSignAuth` library clean and fully platform-agnostic. Overloading would require the core library to continue parsing and depending on Android-specific protos. The chosen approach enforces a cleaner separation of concerns, ensuring that the core library only acts as a pass-through for opaque `Any` payloads.\n\n#SM\n\nPiperOrigin-RevId: 934771494\n",
