Questions and answers
Are UUIDs secure?
No. A UUID is an identifier, not authorization or proof of access.
When are shorter IDs fine?
They are fine for local fixtures, demos, and temporary references where collision risk is controlled.
Should test IDs be stable?
Stable IDs help repeat tests and compare fixtures across runs.
