Should the same client_token request return the same relay_token?

[ch1c0t]

According to the specification(part 3.1, "Alice initiates session),

The same client_token requests should return the same relay_token
until the handshake attempt expires(1m)

For now, it does not seem to be the case. I have created a spec for that. It fails like so:

  1) Alice initiates session /start_session responds with the same relay_token to the same client_token until the handshake attempt expires(1m)
     Failure/Error: expect(first_body).to eq second_body

       expected: "ZfR0K2wBuGZDY6dqXA/DgqEMQzi1WKAml9Cft8lnGO8=\r\n0"
            got: "8Q6DrJt87CAXbRp/6T75qFOSWBu2xPUf0iuNR+dpz+I=\r\n0"

       (compared using ==)

       Diff:

        0

It looks like currently a new relay token is created every time, disregarding the handshake attempt expiration.

I think we should either

1. Remove the note from the specification.
2. Make the reference implementation adhere to the specification.
