Hey - I've left some high level feedback:

• The new Cypress test relies on random sampleId generation, which can make failures harder to reproduce; consider using a deterministic ID or including the generated ID in test logging to ease debugging.
• The metadata tab selection in the test uses visible labels ('Edit'/'View'), which can be brittle against copy changes; consider selecting tabs via more stable attributes such as data-cy or specific roles/indices.
