Powerduck | OpenAPI Studio(@PowerduckLabs):An agent adds an index on `email` to speed up a slow query. It never gets picked up — the WHERE wraps the column in `LOWER(email)`. Plan stays identical. It measured unit-test runtime, called it done, moved on. Where do you verify an index is actually used?
