users.display_name (V6), 3-24 letters, digits, space, _ . -, unique ignoring case. Set in settings (409 DISPLAY_NAME_ALREADY_IN_USE, also for the DB constraint race) and optionally at registration. Returned by /api/users/me.
/actuator/health showed database and disk details to anyone, and /actuator/prometheus was open. Only health stays public, as plain UP/DOWN for the Docker health check.
Unknown email, wrong password and disabled account now all return 401 INVALID_CREDENTIALS; unknown emails still run bcrypt against a dummy hash so timing does not leak them. After 5 failures per email or 20 per client IP, login returns 429 with Retry-After for 15 minutes. LoginRequest is now validated.
JavaScript rounds 17-digit Steam IDs, so 76561198000000001 was stored as
76561198005679790. Steam IDs are now JSON strings (17 digits, numbers
rejected), and null means "no Steam ID" instead of 0 (V4 migrates old rows).
PUT /api/users/settings returns a new token, because Core reads the Steam ID
from the token. A Steam ID owned by another user returns 409.
Move domain packages into a new modules.* hierarchy and rename controller packages to api.* across login, registration, and user modules. Update package declarations and imports (including shared.api DTOs and JwtService -> modules login TokenGenerator), adjust tests and persistence/mapper paths accordingly, and apply minor formatting fixes (missing EOF newlines). This reorganizes the project to better separate API surface and module boundaries.
