- Mask sensitive values (passwords, tokens)

## i18n / Localization
- This project supports up to 21 languages. When modifying user-facing strings, error codes, or labels, always propagate changes to ALL language files (fess_label_*.properties and frontend i18n files).

## Important Patterns for AI Assistants

### Do's
1. Use `@Resource` for field injection (not constructor injection)

								</li>
							</c:if>
							<c:if test="${developmentMode}">
								<li class="nav-item" data-bs-toggle="tooltip" data-placement="left"

Особливо це стосується моделей користувача, тому що:

* **вхідна модель** повинна мати пароль.
* **вихідна модель** не повинна містити пароль.
* **модель бази даних**, ймовірно, повинна містити хеш пароля.

/// danger | Обережно

Ніколи не зберігайте паролі користувачів у відкритому вигляді. Завжди зберігайте «безпечний хеш», який потім можна перевірити.
