` avoid the horizontal layout break.
+* `dashboard.jsp` contains the small technical sentence the user wants removed.
+* `ReaderManagementServlet` manages reader profiles/eligibility/contact/borrowing limits; `UserManagementServlet` manages login accounts/roles/active status. These are overlapping concepts to users but distinct backend workflows.
+
+## Requirements
+
+* Sidebar active state must be based on the original public servlet path, not the forwarded JSP path.
+* Only the matching sidebar item should be active for catalog, books, book categories, reports, and system logs.
+* Remove the sidebar "角色工作台" block.
+* Remove the sidebar "工作台" nav item.
+* Move "报表中心" to the top of the main module navigation for administrator/librarian roles.
+* Fix the header/hero layout on catalog, book management, and reader management so eyebrow/title/description stay grouped vertically.
+* Remove the dashboard sentence: `登录后进入 Dashboard，会话仅保存安全的 AuthenticatedUser 快照、角色代码与权限代码集合。`
+* Reduce the perceived duplication between reader management and user management using conservative UI changes:
+ * Treat reader management as reader profile/borrowing eligibility management.
+ * Treat user management as account/role/login status management.
+ * Prefer clearer labels, descriptions, and cross-links over merging backend flows.
+
+## Acceptance Criteria
+
+* [x] Opening `/catalog` highlights only "馆藏检索".
+* [x] Opening `/books` highlights only "图书管理".
+* [x] Opening `/book-categories` highlights only "图书分类管理".
+* [x] Opening `/reports` highlights only "报表中心" and does not highlight "工作台".
+* [x] Opening `/admin/system-logs` highlights "系统日志".
+* [x] The sidebar no longer displays the role workbench cards or a "工作台" nav item.
+* [x] "报表中心" appears before catalog/books/readers/borrowing for administrator/librarian navigation.
+* [x] Catalog, book management, and reader management hero copy is vertically grouped and does not lay out as separate horizontal items.
+* [x] The dashboard technical session sentence is absent.
+* [x] Reader/user management labels and descriptions make the distinction between reader profiles and user accounts clearer.
+* [x] Maven verification passes or the closest available build command is reported.
+
+## Definition Of Done
+
+* Focused JSP/CSS changes only unless a backend change is required by verification.
+* Existing Servlet/JSP rendering and JSTL escaping behavior remains intact.
+* Maven build/test verification run where available.
+* Trellis quality check completed before final response.
+
+## Technical Approach
+
+* In `header.jspf`, derive a `currentPath` from `requestScope['javax.servlet.forward.servlet_path']` with a fallback to `pageContext.request.servletPath`.
+* Replace broad `fn:contains` checks with exact or prefix checks against public servlet paths.
+* Reorder and trim sidebar markup according to the requested information architecture.
+* Wrap catalog/book/reader hero text in a child `
` to match pages that already render correctly.
+* Remove only the requested dashboard small text, leaving role-specific workbench headings and metrics intact.
+* Use copy changes and cross-links to clarify reader profiles versus user accounts without changing controllers, entities, DAOs, or database schema.
+
+## Out Of Scope
+
+* Merging reader and user management into a single page.
+* Changing authentication, authorization, database schema, or service-layer behavior.
+* Redesigning the whole dashboard or adding new frontend libraries.
+
+## Technical Notes
+
+* Relevant frontend spec index: `.trellis/spec/frontend/index.md`.
+* Relevant files inspected:
+ * `src/main/webapp/WEB-INF/jsp/common/header.jspf`
+ * `src/main/webapp/WEB-INF/jsp/dashboard.jsp`
+ * `src/main/webapp/WEB-INF/jsp/books/catalog.jsp`
+ * `src/main/webapp/WEB-INF/jsp/books/manage.jsp`
+ * `src/main/webapp/WEB-INF/jsp/books/categories.jsp`
+ * `src/main/webapp/WEB-INF/jsp/readers/manage.jsp`
+ * `src/main/webapp/WEB-INF/jsp/admin/users/manage.jsp`
+ * `src/main/webapp/static/css/app.css`
+* Build command from README: `mvn clean package`; fallback path documented as `/home/sjy/.sdkman/candidates/maven/current/bin/mvn clean package` if `mvn` is not on `PATH`.
+* Verification on 2026-04-28:
+ * `git diff --check` passed.
+ * Search for removed sidebar role/workbench and old active-state patterns returned no matches.
+ * `/home/sjy/.sdkman/candidates/maven/current/bin/mvn clean package` passed with `BUILD SUCCESS`.
