 ## Widget System
 
-The frontend is built around a widget system. Widgets are independent, reusable components that display specific information or functionality.
+The UI is composed of reusable widgets found in `src/components/widgets/`. Each widget encapsulates specific functionality or displays data. They support different sizes (`default`, `icon`) for adaptability within various layouts.
-
-* **Widget Sizes:**
-  * `default`: Full column width, suitable for most widgets.
-  * `icon`: Smaller size, designed for use in collapsed sidebars or icon-based menus.
-
-* **Widget Components:** Located in `src/components/widgets/`.  Examples include:
-  * `LoginWidget`:  Login form.
-  * `RegisterWidget`:  Registration information display.
-  * `ButtonWidget`:  Reusable button component.
-  * `StudentCountWidget`, `TeacherCountWidget`, `ProfileInfoWidget`, `PostFeedWidget`, `StudentTableWidget`, `TuitionFeeWidget`: Placeholder widgets to be implemented.
 
 ## API System
 
-The frontend is designed to interact with a backend through a global API system defined in `src/utils/api.ts`.
+Defined in `src/api/api.ts`, this module handles all communication with the backend API.
 
-* **Current Implementation:** The `api.ts` file currently contains **mocked API calls** for demonstration purposes. It simulates API responses using timeouts and hardcoded data.
+* **Live Interaction:** Functions use `fetch` to make requests to the running backend (default: `http://localhost:8080/api`).
-* **Backend Integration:** To connect to a real backend, you will need to replace the mocked API calls in `api.ts` with actual `fetch` requests to your backend endpoints.
+* **SRP Flow:** The `login` function implements the two-step SRP authentication handshake with the backend.
-* **Expected Backend Endpoints (Example):**
+* **Authenticated Requests:** Other API functions automatically include the stored authentication token in the `Authorization: Bearer <token>` header for protected endpoints.
-  * `POST /api/login`: User login.
+* **Error Handling:** Includes basic error handling and detection of unauthorized (401) responses.
-  * `GET /api/user`: Get user data (requires authentication).
+* **Key Endpoints Used:**
-  * `POST /api/logout`: User logout.
+  * `POST /api/auth/srp/start`
-  * `/api/students`, `/api/teachers`, `/api/admin/students`, etc.: Endpoints for managing students, teachers, and other LMS data.
+  * `POST /api/auth/srp/verify`
+  * `POST /api/auth/logout`
+  * `GET /api/profile/{user_id}`
+  * `PUT /api/profile/settings`
+  * `GET /api/admin/dashboard`
+  * `GET /api/admin/students`
+  * `GET /api/admin/students/{student_id}/financials`
 
-## Backend Considerations
+## Backend Interaction Notes
 
-* **Password Hashing (Backend Recommended):**  While `argon2-browser` is included for frontend password hashing demonstration, **it is strongly recommended to implement password hashing (using Argon2id or similar) and salting on the backend for enhanced security.** The frontend should send passwords securely (HTTPS) to the backend, and the backend should handle the hashing and verification process.
+* **Authentication:** The backend handles the secure verification of passwords using SRP. The frontend never stores or hashes the raw password itself after the initial SRP calculation during login.
-* **Authentication and Authorization:** The backend should implement robust authentication (e.g., JWT or session-based) and authorization mechanisms to secure API endpoints and protect sensitive data.
+* **Authorization:** Access to specific API endpoints (e.g., admin routes) is controlled by the backend based on the user's role/permissions associated with their session token.
-* **Database:** The database schema outlined in the initial prompt should be implemented on the backend to store user data, course information, enrollments, etc. (Refer to the initial prompt for database schema details).
+* **Data Source:** All dynamic data (user info, student lists, etc.) is fetched from the backend, which interacts with the MariaDB database.
-* **Backend Technology:** You can choose any suitable backend technology (Node.js, Python, Java, PHP, etc.) to build the API endpoints and connect to the database.
 
 ## Further Development
 
-* **Implement Modal Module:** Create a reusable `ModalModule` component in `src/components/modules/ModalModule.ts` to handle modals for various purposes (e.g., classrooms under construction, account settings).
+* **Complete Widget Functionality:** Ensure all widgets fetch and display real data from the backend API.
-* **Complete Widget Implementations:** Implement the remaining placeholder widgets in `src/components/widgets/` (e.g., `StudentCountWidget`, `TeacherCountWidget`, `ProfileInfoWidget`, `PostFeedWidget`, `StudentTableWidget`, `TuitionFeeWidget`) to display actual data from the backend.
+* **Admin Page Enhancements:** Implement full CRUD operations for student/teacher management, filtering, batch actions, and enrollment assignments.
-* **Account Settings Modal:** Develop the Account Settings Modal to allow users to edit their profile information and change passwords.
+* **Student Table Widget:** Integrate a robust table library (e.g., Tabulator, TanStack Table) for improved sorting, filtering, and pagination.
-* **Admin Page Functionality:** Implement the functionality for the Admin page, including student and teacher management, using appropriate widgets and API calls.
+* **Classrooms Module:** Build out the Classrooms feature beyond the placeholder modal.
-* **Student Table Widget:** Integrate a table library (e.g., Tabulator, DataTables) into the `StudentTableWidget` for enhanced table features like sorting, filtering, and pagination.
+* **Robust Error Handling:** Implement more comprehensive error handling and user feedback mechanisms throughout the UI.
-* **Classrooms Page/Modal:**  Implement the Classrooms feature, potentially starting with a modal indicating "Under Construction" as initially requested, and then expanding to a full Classrooms page with relevant widgets.
+* **Client-Side Validation:** Add more input validation for forms (e.g., account settings).
-* **Form Validation:** Add client-side form validation to login, registration (if implemented), and account settings forms for better user experience.
+* **UI/UX Polish:** Refine styling, transitions, and interactions for a smoother user experience.
-* **Error Handling:** Improve error handling in API calls and display user-friendly error messages.
+* **Testing:** Implement unit and potentially end-to-end tests.
-* **Styling and UI Polish:** Enhance the visual design and user interface with custom CSS and Bootstrap components to create a polished and professional LMS frontend.
+* **State Management:** For larger applications, consider introducing a dedicated state management library (like Zustand, Pinia, Redux Toolkit) instead of relying solely on `utils.ts`.
-* **Backend Integration:** Replace the mocked API calls with real API calls to your backend endpoints to connect the frontend to the backend data and functionality.

+  > b.  Onboarding materials suitable for learners, such as a concise user guide document and potentially referencing the Video Demonstration.
+  >
+  > c.  A formal handover meeting and documentation transfer concluding the development and deployment phases outlined in Exhibit C.
+
+## ARTICLE 5: TESTING AND ACCEPTANCE
+
+5.1 **Testing:** Developer shall perform internal testing throughout the development process, appropriate to the Agile methodology. This includes developer testing (e.g., unit tests where applicable), integration testing of components, and functional testing against requirements defined for each Sprint.
+
+5.2 **User Acceptance Testing (UAT):** Client shall be responsible for conducting UAT. Developer shall notify Client when specific features, modules, or System increments are ready for UAT (typically at the end of Sprints or designated UAT phases as shown in Exhibit C). Client shall perform UAT in accordance with mutually agreed-upon test plans or use cases based on the Acceptance Criteria. Client shall have **[Specify duration, e.g., ten (10) business days]** from such notification to conduct UAT for the provided increment and report any identified material defects or non-conformities ("**Defects**") to Developer in writing via the agreed project tracking tool ([Tool name from 2.2.c]). Failure to report Defects within the specified period may be deemed acceptance of that increment for the purpose of proceeding with development, without prejudice to addressing Defects identified later within the Warranty Period.
+
+5.3 **Acceptance Criteria:** The System (or relevant increment) shall be deemed formally accepted by Client upon the earliest occurrence of:
+  > (a) Client providing Developer with written notice of acceptance; or
+  >
+  > (b) Client using the delivered System or increment in a live production environment for its intended operational purposes (excluding UAT activities); or
+  >
+  > (c) The expiration of the final UAT period for the complete System (as per the timeline in Exhibit C) without Client providing written notice of material Defects that prevent acceptance according to the agreed Acceptance Criteria.
+  >
+  > Acceptance Criteria shall primarily be based on the functional requirements defined in the project backlog and specifications developed during the Sprints, demonstrating that the System operates substantially as intended.
+
+5.4 **Defect Resolution:** Developer shall use commercially reasonable efforts to correct any material Defects identified during UAT and properly reported by Client within the agreed timeframe. Defect prioritization and resolution timelines will be managed as part of the Agile backlog grooming and sprint planning process. Resolution of minor defects or cosmetic issues may be deferred to subsequent Sprints or the Warranty Period by mutual agreement.
+
+## ARTICLE 6: CHANGE MANAGEMENT
+
+6.1 **Change Request Process:** Both Parties acknowledge that requirements may evolve. Any proposed change to the agreed-upon Scope of Services, features, specifications, or Deliverables after the initial baseline established during planning ("**Change Request**") must be submitted in writing by either Party to the other Party's designated project contact.
+
+6.2 **Impact Assessment:** Upon receipt of a Change Request, Developer shall promptly assess its potential impact on the project scope, technical feasibility, estimated timeline, resource allocation, and overall project cost. Developer will provide Client with a written impact analysis, including any proposed adjustments to fees or schedule, within **[e.g., five (5) business days]**, or a longer period if mutually agreed for complex requests.
+
+6.3 **Approval:** Developer shall not proceed with implementing any Change Request until both Parties have formally agreed in writing (e.g., through a signed Change Order document referencing this Agreement) to the Change Request itself, its assessed impact, and any associated adjustments to the Agreement's terms, including fees and timeline. Approved Change Orders shall become part of this Agreement.
+
+## ARTICLE 7: PROJECT CONSIDERATIONS AND RISK MITIGATION
+
+7.1 **Potential Scope Evolution:** Client acknowledges that the flexibility inherent in the Agile process necessitates active participation and decisive feedback from Client representatives to manage scope effectively. Both Parties agree to utilize the Change Management process (Article 6) diligently to ensure that scope adjustments are intentional, documented, and their impacts understood and agreed upon, thereby mitigating risks to project timelines and budget.
+
+7.2 **Initial Setup and Data Migration:**
+
+  > a.  Client Responsibilities: Client is responsible for providing necessary access to its infrastructure (if applicable), timely feedback, subject matter expertise, and ensuring user readiness for the System implementation. Client shall designate key personnel to participate in project meetings, reviews, and UAT.
+  >
+  > b.  Data Migration: **[Select ONE option based on agreement, requires confirmation]:**
+  >   *   **Option 1 (Migration Not Included/Basic Assistance):** Data migration from Client's existing systems is not included in the scope of Services under the base Fees. Developer may provide reasonable assistance with defining data formats or validating imported data, subject to separate agreement or Change Order if significant effort is required. Client is primarily responsible for extracting, cleansing, formatting, and importing its data.
+  >   *   **Option 2 (Migration Included - Define Scope):** Data migration services for [Specify data types, e.g., user profiles, basic course structures] from [Specify source system(s)] are included in the Scope of Services. A detailed Data Migration Plan outlining responsibilities, formats, timelines, and validation procedures shall be developed collaboratively by the Parties early in the project. Client remains responsible for the accuracy and completeness of source data provided. Complexities discovered during migration may necessitate a Change Request.
+  >
+  > c.  Support and Training: Developer commits to providing the onboarding support, training, and documentation outlined in Articles 2, 4, and associated Exhibits to mitigate challenges associated with system transition and user adoption.
+
+## ARTICLE 8: FEES AND PAYMENT SCHEDULE
+
+**8.1 Fees and Payment Terms:** **The total fees, billing rates (if applicable), invoicing procedures, and payment schedule for the Services rendered under this Agreement shall be detailed in a separate Payment Schedule document (designated as Exhibit D), which shall be mutually agreed upon by the Parties in writing and incorporated herein by reference upon execution.** Exhibit D shall specify currency (Philippine Peso - PHP, unless otherwise agreed), payment milestones or frequency, and payment terms (e.g., Net 30 days from invoice date).
+
+8.2 **Expenses:** Unless otherwise specified in Exhibit D, Developer shall bear its own general overhead costs. Any direct, out-of-pocket expenses reasonably incurred by Developer specifically for the project (e.g., pre-approved travel, specific third-party software licenses necessary for the deliverable) shall be reimbursable by Client only if pre-approved by Client in writing. Invoices for approved expenses shall include supporting documentation.
+
+8.3 **Taxes:** Each Party shall be responsible for its own taxes imposed by relevant authorities. Fees specified in Exhibit D are exclusive of any applicable Value Added Tax (VAT) or other sales taxes, which, if applicable, shall be added to Developer's invoices and paid by Client.
+
+## ARTICLE 9: INTELLECTUAL PROPERTY RIGHTS
+
+9.1 **Ownership of Custom Developed System:** Subject to Client's full payment of all fees due under this Agreement and Developer's reservation of rights in Pre-Existing IP (Section 9.2), Developer hereby assigns to Client all right, title, and interest in and to the custom Source Code and associated Deliverables specifically created by Developer for Client under this Agreement (the "**Custom Developed IP**").

DEVELOPER DOES NOT WARRANT THAT THE SYSTEM WILL BE ERROR-FREE, UNINTERRUPTED, OR MEET ALL OF CLIENT'S REQUIREMENTS.**
+
+## ARTICLE 12: LIMITATION OF LIABILITY
+
+12.1 **Exclusion of Indirect Damages:** **IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY OR ANY THIRD PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES (INCLUDING, BUT NOT LIMITED TO, LOST PROFITS, LOST REVENUE, LOST DATA, LOSS OF GOODWILL, OR BUSINESS INTERRUPTION) ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR THE USE OR PERFORMANCE OF THE SYSTEM OR SERVICES, REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, OR OTHERWISE), EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.**
+
+12.2 **Cap on Direct Damages:** **EXCEPT FOR LIABILITY ARISING FROM A PARTY'S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS (ARTICLE 10), INDEMNIFICATION OBLIGATIONS (IF ANY - NOT CURRENTLY INCLUDED, CONSIDER ADDING), OR INFRINGEMENT OF THE OTHER PARTY'S INTELLECTUAL PROPERTY RIGHTS, EACH PARTY'S TOTAL AGGREGATE LIABILITY TO THE OTHER PARTY FOR ALL CLAIMS FOR DIRECT DAMAGES ARISING OUT OF OR RELATING TO THIS AGREEMENT, WHETHER IN CONTRACT, TORT, OR OTHERWISE, SHALL NOT EXCEED THE TOTAL AMOUNT OF FEES ACTUALLY PAID BY CLIENT TO DEVELOPER UNDER THIS AGREEMENT DURING THE TWELVE (12) MONTH PERIOD PRECEDING THE EVENT GIVING RISE TO THE CLAIM.** *(Note: This cap is often heavily negotiated. Alternatives include a fixed amount or excluding certain types of direct damages).*
+
+12.3 **Basis of Bargain:** The Parties acknowledge that the limitations of liability and disclaimers of warranties set forth in this Agreement reflect the agreed-upon allocation of risk between the Parties and form an essential basis of the bargain, without which Developer would not have entered into this Agreement on the terms provided.
+
+## ARTICLE 13: TERM AND TERMINATION
+
+13.1 **Term:** This Agreement shall commence on the Effective Date and shall continue until all Services are completed, the System is Accepted, final payment has been made, and the Warranty Period has expired, unless terminated earlier pursuant to the terms of this Article 13. The initial intended development and deployment term is estimated in Exhibit C. The overall Agreement duration might extend based on mutually agreed support terms beyond the initial delivery (as suggested by the "3-5 Year Term" note, which requires separate definition, likely in a Support Agreement).

+  > a.  Developer shall cease performing Services and shall promptly deliver to Client all completed Deliverables and work-in-progress, including Source Code for Custom Developed IP up to the date of termination.
+  >
+  > b.  Client shall pay Developer for all Services performed and accepted Deliverables provided up to the effective date of termination, plus any pre-approved, non-cancelable expenses incurred. If termination is by Client for convenience (if Option A or B is chosen), Client shall also pay **[Specify additional amount, e.g., "a termination fee equivalent to X% of the remaining estimated project fees" or "for the work completed during the notice period"]**.
+  >
+  > c.  Each Party shall promptly return or, at the Disclosing Party's request, destroy all Confidential Information of the other Party in its possession or control.
+  >
+  > d.  Any provisions of this Agreement that by their nature should survive termination (including, but not limited to, Articles 9, 10, 11.2, 12, 14, and payment obligations accrued prior to termination) shall survive.
+
