// This file (selected by the "signal_legacy" build tag) links against the
// pre-fork libsignal-protocol-c instead of libomemo-c - e.g. on Debian
// bullseye, which packages the former (libsignal-protocol-c-dev) but not
// the latter (libomemo-c-dev only arrived in bookworm). Vanilla
// libsignal-protocol-c only ever produces/consumes protocol v3 (legacy/
// siacs OMEMO) messages; see capability_legacy.go, version_legacy.go,
// deserialize_legacy.go, and signedprekey_legacy.go for the resulting
// reduced-capability shims.
