Harborview Veterinary Group's agent passed all its test cases three months ago. Since then, two new custom actions and a revised topic instruction were added. What should happen before the next production deployment?

Short Explanation
A pass three months ago is a photograph, not a live feed. Every new action or instruction is a chance to knock something else off balance, so re-run the whole regression suite, not just the new pieces.
Full Explanation
Testing is not a one-time gate; it is a lifecycle activity. Because two new custom actions and a revised topic instruction were added since the last pass, Harborview should re-run the full regression test suite in Testing Center to both validate the new functionality and confirm nothing that previously worked was broken by the changes. Assuming a prior pass still holds ignores that the reasoning engine's behavior can shift meaningfully when topics, actions, or instructions change, and stale confidence is exactly what regression testing exists to prevent. Relying on pet-owner complaints after deployment turns real, sometimes distressed, owners into unwitting testers for a healthcare-adjacent service — the opposite of controlled, pre-deployment validation. Testing only the two new actions in isolation misses the point that a revised topic instruction can shift classification behavior for utterances that used to route correctly elsewhere, so full regression coverage matters, not just coverage of what changed. The disciplined pattern the exam expects: any meaningful configuration change triggers a fresh full regression pass before the next deployment.
