test vectors: inconsistency in random scalars

[NikZak]

Hi. When I look at section 8.4.5.2
or section 8.4.5.1
random scalars go as

random scalars:
    r1 = "60ca409f6b0563f687fc471c63d2819f446f39c23bb540925d9d4254ac58f3
          37"
    r2 = "2ceff4982de0c913090f75f081df5ec594c310bb48c17cfdaab5332a682ef8
          11"
    e_tilde = "6101c4404895f3dff87ab39c34cb995af07e7139e6b3847180ffdd1bc
               8c313cd"
    r1_tilde = "0dfcffd97a6ecdebef3c9c114b99d7a030c998d938905f357df62822

    r3_tilde = "639e3417007d38e5d34ba8c511e836768ddc2669fdd3faff5c14ad27

When I look at section 8.4.5.3 random scalars are:

random scalars:
    r1 = "44679831fe60eca50938ef0e812e2a9284ad7971b6932a38c7303538b712e4

    m_tilde_scalars:

There are few issues with it.
First:
How were the first random scalars derived? This is not defined in the standard. I've figured that you can get them by using seeded_random_scalars(SEED, DST, count) where SEED = "332e313431353932363533353839373933323338343632363433333833323739" and DST =
"BBS_BLS12381G1_XMD:SHA-256_SSWU_RO_H2G_HM2S_MOCK_RANDOM_SCALARS_DST_" but I had to make a few guesses to find that. I think this better be defined in the standard.

Second:
How second random scalars are derived, I don't know

I mean you may argue that how the random scalars are derived is not necessary to run the tests. But then why defining seeded_random_scalars function and saying that it is used to get random scalars. This function can not be used so the whole section about seeded_random_scalars is redundant
