async fn post_state_signature(
state: &Arc<RwLock<StateRelayServerState>>,
headers: &HeaderMap,
body: &[u8],
) -> Result<(), RelayError>Expand description
Handle a POST to state/api/state: tries LCV3, then LCV2 (auto-downgrading to LCV1 if the
signature verifies against the legacy scheme), then LCV1. Mirrors tide’s poststatesignature.
