How do I keep impure functions at the edges of the system when the domain logic determines if they get called in the first place?

  Functional (and opinionated) errors handling in Clojure (by fmnoise)

Here the business logic of whether to fetch managed users or current manager is moved to a pure function. The actual fetching of the data from the db is a straightforward lookup table. data-get-login-form-from-request, data-get-session-data and success-response are pure. Using a library like flow, the entire if form can be written as a thread first, so that reduces the cyclomatic complexity further.
