First Administrator
Create or confirm the first AutoCore administrator through the source-verified installation setup contract.
The API setup contract supports administrator mode: create for a clean installation or mode: confirm for an authenticated administrator. Creation requires an email, display name, matching password confirmation, and a password of 12–128 characters containing lowercase, uppercase, number, and symbol characters.
The created account is active, email-verified by the setup contract, and receives the super_admin role. Passwords are hashed and are not returned. Authenticated setup cannot create a second administrator through the unauthenticated creation path.
Verification
Confirm the setup response, then authenticate through the configured application path. Do not publish or reuse any real credentials. A completed installation rejects ordinary repeated completion; preserve the conflict response as evidence rather than forcing a second initialization.
