database	User Table	The `user` table — accounts, roles, and statuses.	database user auth	2026-07-21T14:18:00Z

Schema

Column	Type	Description
id	TEXT PK	UUID v4 generated on creation.
username	TEXT	Unique login name.
password_hash	TEXT	Argon2id hash (memory/time/parallelism from env config).
role	TEXT	'admin' or 'player'. Default 'player'.
status	TEXT	'enabled' or 'disabled'. Default 'enabled'.
created_at	TEXT	ISO 8601 timestamp (strftime('%Y-%m-%dT%H:%M:%fZ','now')).

Constraints

• Unique on username.
• role is enforced application-side (see AdminService.updateUserRole).
• status is checked by AuthService.login and AuthService.refresh — disabled users cannot log in or refresh.

Invariants

• The application enforces the last-admin invariant: at least one enabled user with role = 'admin' must always exist. Attempts to demote or delete the last admin are rejected by UsersService.enforceLastAdminInvariant (used by AdminService.updateUserRole and AdminService.deleteUser).

First-admin bootstrap

When the user table is empty of admins, POST /api/v1/auth/register-first-admin is the only endpoint that can create one. After that, the endpoint returns 409 SYSTEM_INITIALIZED.
