Interface TransportPlatformDefaults

Whether the network-session pair's presence follows the process start on this platform's profile. Android's profile defaults to emitting no pair and is opted in for a process that began with a stored session; iOS's profile emits the pair from its own default, so the process-start fact is not passed there. The flag is the platform's contract, so the iOS behavior is declared rather than left to the profile-name literal.

Whether the profile takes the app's pqcEnabled (the post-quantum hybrid key share) from the process start: the transport requires pqc for android.http and refuses it for ios.http (@igpapi/transport 0.9.21), and the value is the device's state the transport never picks for the caller — true for a process that began with a stored session, false for a fresh install or a logged-out process. The flag is the platform's contract, so a profile the transport refuses the option for declares it off rather than being recognised by its name.

The transport profile (TLS and QUIC ClientHello, header order) for both channels.

The protocol mode used when the caller sets none.
