The athletes this user actually trains with.

A separate endpoint rather than a filter on the list above, deliberately. That one is the public marketplace; filtering it per user would put a per-user body on a public endpoint, which the next person to re-add response caching there would serve to the wrong person. So this one is private, no-store and that one stays anonymous.

Never gated, and it lists locked athletes too: a paused athlete missing from the roster would leave no route to the screen that resumes them.
