is a platform allowing the public to report civic issues (road damages, mosquito breeding, garbage collection, etc.) with images, descriptions, and GPS locations. An ML layer classifies and assigns these issues to respective institutions. Institutions use a web admin portal to manage issues, update data, and view analytics. + +**Tech Stack:** +- **Backend:** Go (API) +- **Frontend (Admin Panels):** Next.js +- **ML/Agentic Layer:** Python with LangGraph +- **Mobile App:** React Native (Not in scope for this phase) +- **File Upload/Download:** Handled separately (already assigned). + +--- + +## 1. Backend (Go API) + +### Current Status: +- **Database & Schema Design:** `[DONE]` (PostgreSQL schemas for Users, Entities, Cases, Evidence, and Status History are set up). +- **Authentication & Authorization:** `[DONE]` (JWT-based auth, RBAC, and permissions are implemented). +- **Issue Management (CRUD):** `[DONE]` (Endpoints to submit cases, assign cases, and update status exist). +- **Institution Management:** `[DONE]` (Entities CRUD is implemented). +- **Analytics & Reporting endpoints:** `[PARTIAL]` (A basic `/cases/stats` endpoint exists, but may need expansion). + +### What remains to be Implemented / Corrected: +1. **Analytics & Reporting endpoints** + - **Steps:** Expand the existing `/cases/stats` or create new endpoints returning aggregated data (e.g., issues by category, resolution times, issues per region) specifically for the frontend dashboard charts. +2. **Integration with ML Layer** + - **Steps:** Currently, cases are submitted and stay unassigned unless manually assigned. We need an HTTP client in Go to asynchronously call the Python ML service upon `SubmitCase`. It should send the description, image URL, and GPS. Once the ML service responds, update the issue record with the returned classification and assigned institution ID via a webhook or internal callback. + +--- + +## 2. ML Layer (Python with LangGraph) + +### Current Status: +- **Project Structure & Dependencies:** `[DONE]` (Basic setup with LangGraph exists). +- **LangGraph Agent Workflow:** `[PARTIAL]` (A workflow is defined in `main.py`, but it operates as an interactive CLI chatbot rather than a structured API). + +### What remains to be Implemented / Corrected: +1. **API Server Setup** + - **Steps:** Replace or augment the CLI `main.py` by exposing a REST API to receive issue details (JSON) from the Go backend. + - **Tech:** FastAPI. +2. **LangGraph Workflow Refactoring** + - **Steps:** Update the state graph to accept a structured payload (description, image URL, coords) instead of arbitrary human messages. The nodes must be configured to perform specific classification and entity assignment tasks, returning structured JSON output rather than conversational text. +3. **LLM Integration (Vision & Text)** + - **Steps:** Ensure the LLM tools can process image URLs (passed from the upload module) alongside text and GPS data to classify the issue and map it to the correct institution UUID. + - **Automated Tests:** Use `pytest`. Write tests for individual graph nodes using mocked LLM responses. + +--- + +## 3. Frontend (Next.js Admin Panels) + +### Current Status: +- **Project Setup & Routing:** `[DONE]` (Next 15 with App Router, basic structure in `src/app` including `admin`, `login`, and `(portal)`). +- **Tooling & Configuration:** `[DONE]` (Playwright, Vitest, Tailwind, ESLint). + +### What remains to be Implemented / Corrected: +1. **Authentication Flow** + - **Steps:** Implement the login page form submission to the Go backend `POST /api/v1/auth/login`. Store JWT securely and manage session state across the app using contexts or hooks. +2. **Dashboard (Analytics)** + - **Steps:** Fetch data from Go backend analytics endpoints. Display charts (issues over time, by category, resolution rate). + - **Tech:** Chart.js, Recharts, or Tremor. +3. **Issue Management Interface** + - **Steps:** + - **List View:** Table displaying assigned issues with filtering (by status, date) and pagination. + - **Detail View:** Show issue description, image, map rendering the GPS location, and current status history. + - **Actions:** Buttons to change status (In Progress, Resolved, Rejected), add internal notes. +4. **Institution Profile Management** + - **Steps:** Forms for institutions to update their details. + - **Automated Tests:** Unit tests for React components using `Jest`/`Vitest` and `React Testing Library`. Test user interactions by mocking API calls. + +--- + +## 4. End-to-End Manual Testing Workflow + +1. **Issue Creation Simulation:** Use Postman or curl to hit the Go API `POST /api/v1/cases` endpoint. Provide dummy text, GPS coordinates, and an image URL (using the upload module). +2. **ML Pipeline Verification:** Verify the Go API logs to ensure it successfully called the Python ML service. Check the database to confirm the issue was updated with the predicted category and assigned institution. +3. **Admin Login:** Open the Next.js app locally. Log in using credentials for the institution that was assigned the issue. +4. **Dashboard & UI Verification:** Check if the new issue appears in the dashboard metrics and the main issue list. +5. **Issue Resolution:** Click on the new issue to view details. Verify the image loads and the map shows the correct location. Change the status to "Resolved". +6. **Data Persistence:** Reload the page to verify the status update persists. Query the database directly to ensure the status history recorded the status change.
