Get My Interest

Whether the caller has shown interest in this role.

Its own endpoint rather than a field on GET /api/public/roles/{id}, and the reason is the cache. That response is anonymous and shared-cacheable -- identical bytes for every reader, which is what makes a role page cheap. One per-viewer boolean in it would force private, no-store on the whole payload and turn every visit into an origin hit. So the expensive, shared, crawlable half stays shared, and the one bit that differs per person is a second small request that only a signed-in reader ever makes.

Answers for a CLOSED role too, unlike the write paths: a candidate looking at a role that closed should still be told they had put their hand up.
