**original_problem_statement:** The user wants to build a full-stack personal training management system called Abbas FIT. It's a mobile-first application for a gym trainer (Abbas) and his clients.

**PRODUCT REQUIREMENTS:**
- **Tech Stack:** Expo (React Native) frontend, FastAPI (Python) backend, MongoDB database. JWT for authentication. Gemini API for AI features, using the Emergent Universal LLM Key.
- **Roles:**
    - **Admin (Abbas):** Full access. Can add/edit users, assign diet/workout plans, view all user insights, and set goals.
    - **User (Client):** Can only access and modify their own data.
- **Key Features Requested:**
    - **Authentication:** Login for admin and users. Admin default credentials are admin/admin.
    - **User Management (Admin):** Add/edit clients (name, email, physical stats).
    - **Goal Setting (Admin):** Set user goals for steps, water intake, weight loss/gain, muscle gain during onboarding.
    - **Diet Plans (Admin):** Create detailed diet plans with 7 meal slots (Breakfast, mid-morning snack, lunch, afternoon snack, pre-workout, post-workout, dinner) and assign supplements.
    - **Progress Tracking (Admin & User):** Admin can track client's food/supplement intake and goal adherence. Users can upload weekly photos and vitals (height, weight). The app should allow for week-over-week comparison of food intake and physical activity.
    - **AI Features:** AI-powered goal predictions based on user activity.
    - **Notifications:** In-app notifications to remind users to log meals and water intake.
    - **Deployment:** The user wants the entire application (frontend, backend, DB) to be deployable on their own external hosting. The frontend should be accessible as both a native mobile app and a website.

**User's preferred language**: English

**what currently exists?**
A full-stack application foundation is in place.
- **Backend (FastAPI):** The  file has been completely rewritten to include Pydantic models and initial (untested) API stubs for all the newly requested features like step/water goals, enhanced diet plans, weekly check-ins, and user onboarding goals. It is configured to use a MongoDB database and JWT authentication.
- **Frontend (Expo):** A basic file structure exists with  for navigation, including layouts and screens for a landing page, login, and separate admin/user dashboards. It includes basic UI for the initial MVP but does **not** contain any of the UI for the newly requested features. The frontend is out of sync with the rewritten backend.
- **Deployment:** The project contains Docker files (, ), an Nginx configuration (), and a  guide to facilitate external deployment for both the backend and the web version of the frontend.

**Last working item**:
- **Last item agent was working:** The agent performed a complete rewrite of the backend server file () to incorporate a large number of new features requested by the user, including enhanced diet plans, goal setting, and weekly check-ins. The goal was to update the data models and API structure to support these new features.
- **Status:** IN PROGRESS
- **Agent Testing Done:** N (The rewritten backend is completely untested).
- **Which testing method agent to use?** backend testing agent ()
- **User Testing Done:** N

**All Pending/In progress Issue list**:
- **Issue 1: Untested Backend Overhaul (P0)**
  - **Description:** The entire backend logic in  was rewritten to add new features but was never tested. It is critical to validate, debug, and stabilize the backend before any frontend work can proceed.
  - **Attempted fixes:** None. The rewrite was the last action taken.
  - **Next debug checklist:**
    1.  Invoke the  agent to perform a comprehensive test run on .
    2.  Carefully review the test results for any errors, crashes, or logical flaws in the new endpoints.
    3.  Apply the fixes suggested by the testing agent.
    4.  Manually run  commands against the new endpoints (e.g., creating a user with goals, assigning a new diet plan) to double-check the logic.
  - **Why fix this issue and what will be achieved with the fix?** A stable and tested backend is mandatory. This will unblock all frontend development for the new features.
  - **Status:** NOT STARTED
  - **Is recurring issue?** N
  - **Should Test frontend/backend/both after fix?** backend
  - **Blocked on other issue:** None

**In progress Task List**:
- **Task 1: Implement New Features on the Frontend (P0)**
  - **Description:** The frontend UI and logic must be built to match the new backend capabilities.
  - **Where to resume:**
    1.  Update the frontend API service in  to add functions for all the new backend endpoints (goals, diet plans, check-ins, etc.).
    2.  Create or modify the admin screens to allow setting goals, creating detailed diet plans, and viewing user progress.
    3.  Create or modify the user screens to display goals, log detailed meals, and upload weekly check-ins.
  - **What will be achieved with this?** This will make the user's requested features functional and visible in the application.
  - **Status:** NOT STARTED
  - **Should Test frontend/backend/both after fix?** both
  - **Blocked on something:** Issue 1: Untested Backend Overhaul.

**Upcoming and Future Tasks**

None. The agent has been following the user's requests, although the latest implementation is pending testing.

**Known issue recurrence from previous fork**
None. This is the first handover.

**Code Architecture**


**Key Technical Concepts**
- **Frontend:** Expo, React Native, TypeScript, Zustand (state management),  (file-based routing), Nativewind (for styling).
- **Backend:** FastAPI (Python), MongoDB (via ), Pydantic (data validation), JWT (authentication).
- **Deployment:** Docker, Docker Compose, Nginx.

**key DB schema**
Inferred from the new  models:
- **users:** 
- **goals:** 
- **onboarding_goals:** 
- **diet_plans:** 
- **meals:** 
- **check_ins:** 
- **testimonials:** 
- **contact_submissions:** 

**changes in tech stack**
- The user's initial request for Supabase was changed to **MongoDB + JWT Authentication** based on their preference.

**All files of reference**
- : Recently rewritten to add all new features. **This is the most critical and unstable file.**
- : Contains instructions for external deployment.
- : Defines the services (backend, db, web) for Docker deployment.
- : Needs to be updated to match the new backend APIs.
- : Admin-facing screens, will require significant additions.
- : User-facing screens, will require significant additions.

**Areas that need refactoring**:
- : This file is now completely out of date. It must be refactored to include API client methods for all the new endpoints in  (goals, check-ins, new diet plans, etc.).

**key api endpoints**
Based on the new  (needs verification via testing):
-  (POST): User login.
-  (POST, GET): Create and list users.
-  (PUT): Set step/water goals.
-  (PUT): Set initial weight/muscle goals.
-  (POST, GET): Create and list diet plans with the new 7-meal structure.
-  (POST, GET): Submit and retrieve weekly check-ins with photos.
-  (GET): Get public testimonials.
-  (POST): Submit contact form.

**Critical Info for New Agent**
- **PRIORITY #1: Test the backend.** The  file was just completely rewritten and is untested. Use the  agent immediately. Do not proceed with any frontend changes until the backend is stable.
- The user's end goal is to deploy this application on their **own hosting**. The project has been structured with Docker for this purpose. Keep this in mind for all future development.
- The frontend is significantly behind the backend. After stabilizing the backend, the main task will be a large-scale frontend build-out of all the new features.
- The user wants both a **mobile app and a website** from the same Expo codebase. Ensure all new UI is responsive and works on both platforms.

- **Msg 58:** Asked to change the backend to PHP/cPanel. (Status: REJECTED - platform constraint. Agent offered a web admin panel as an alternative).

**Project Health Check:**
- **Broken:**
    - The backend in  is entirely new and untested. It is presumed to be broken until proven otherwise.
    - The contract between the frontend and backend is broken. The frontend  and UI components do not reflect the new backend structure.
- **Mocked:**
    - No mocked data is currently in use.

**3rd Party Integrations**
- **Gemini:** Intended for AI features like meal logging. Uses the Emergent LLM Key. The integration is planned but **not yet implemented**.

**Testing status**
- **Testing agent used after significant changes:** NO (A major backend rewrite was just performed but not tested).
- **Troubleshoot agent used after agent stuck in loop:** NO
- **Test files created:** None.
- **Known regressions:** None yet, as the new features have not been integrated into the frontend.

**Credentials to test flow:**
- **Username:** 
- **Password:** 

**What agent forgot to execute**
- The agent's most critical oversight was not immediately testing the completely rewritten . This leaves the project in an unstable state.
- Many features from the original PRD have not been started, as the agent has been reacting to the user's evolving requests. These include the AI meal logger, workout library, and scheduling.
