🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear the cookie on the invalid-token path.

User::getUserByRememberToken() can return null, and that branch returns before this SessionCookieHelper::clear() call. Logout then leaves a stale remember_token in the browser. Move the clear before that return so valid and invalid tokens are both removed.

In `@backend/app/Controllers/User/Auth/AuthLogoutController.php` at line 98,
Update the invalid-token branch in AuthLogoutController so
SessionCookieHelper::clear() executes before returning when
User::getUserByRememberToken() returns null. Preserve the existing
cookie-clearing behavior for valid tokens, ensuring both logout paths remove the
remember_token.

Document the new lockout response.

Line 246 adds a 429 response, but the OpenAPI declaration does not list it. Add the 429 response contract so generated clients can handle the lockout path.

Keep lockout state indistinguishable before authentication.

A known account returns ACCOUNT_LOCKED with retry_after, while an unknown account returns INVALID_CREDENTIALS. This exposes account existence through the public login endpoint.

Return the same generic credential response during lockout. Do not expose lockout metadata before authentication.

Denial of Service (CWE-799)

Reachability: External · Exploitability: Moderate

Do not make a known account identifier an availability kill switch.

For a known account, ten failed passwords within 15 minutes create a 15-minute account lock before password verification. An attacker can repeat this cycle and block the account owner from logging in. Replace the hard lock with an escalating challenge or delay that does not deny authentication to every client. IP-only controls do not stop distributed requests.

In `@backend/app/Controllers/User/Auth/LoginController.php` at line 272, Update
the known-account failure handling around LoginController and
AccountLockoutHelper::recordFailure so repeated failed passwords no longer
create a universal account lockout that denies the owner authentication. Replace
the hard lock with an escalating challenge or delay applied without blocking
every client, while preserving password verification and addressing
distributed-request abuse rather than relying only on IP-based limits.
