Random tests keep generating datasets where authors with the same username have different names in the same dataset:

[
  {
    id: 'post1',
    author: { username: 'user6', name: 'User 1' },

user6 has 3 different names in the same object.

Some things are not clear from description:

• are only post authors to be considered or also comment authors for the resulting "authors" state?
• what is the expected order of elements in the state?
• what is the purpose of the id field in the authorPost state, as it's always the same as postId?
