this is something in addition to the multiple environments that require prefect to be installed. There is the agent process that could run on hostA. There is the execution environment where the agent deploys the flow run which also requires prefect to be installed (lets say on hostB), then there is the orion service (webservice) that runs on a hostC that also requires prefect to be installed. In each of these cases the .prefect project directory gets created, and I'm confused as to why and what prefect environment variables to set for each of these hosts. Will continue to discover in the meantime while I await feedback.
