The publicUrl on an exam or practice space — the shareable link you get back from endpoints like GET /exams/{id} — now points at your first-party Examplary domain. A test comes back as https://app.examplary.ai/l/{id} and a practice space as https://app.examplary.ai/s/{id}, or at your workspace's custom domain when you've set one up. Until now these links used the separate examplary.link and practice.space short domains.
First-party links are far less likely to be flagged or blocked by school networks and email filters, so the tests you hand to students are easier to reach. Nothing about the request changes — only the host and path of the URL you get back.
Links already in the wild keep working: the old examplary.link and practice.space addresses redirect to the new ones. If you store or parse these URLs, re-fetch them or update anything that expected the old domains.
