As long as no `solutions` object has been set or unresolved collisions exist,
no data is written to the database. A schedule is only created if at least

In order to resolve any possible conflicts, the client must submit a new request with
a solution for each conflict. Possible solutions are listed as part of the projected
timeslot in the `solution_choices` array. In a best-case scenario with no detected
conflicts an empty solutions object will suffice. For more details on the individual
types of solutions see the SolutionChoicesEnum.

If there's more than one collision for a projected timeslot, only `theirs` and `ours`
