# Project Context: Local Food AI

## 🎯 Vision Statement
A strictly local, privacy-first Food AI that acts as a clinical dietitian. It provides complete nutritional analysis, recipe formulation, and menu planning based on dynamic user health profiles (e.g., pregnancy, kidney disease, specific diets). No user data leaves the server.

## 🏗️ Architecture & Tech Stack
- **Server Environment**: Ubuntu 24.04 VM (`192.168.130.170`). 
- **Containerization**: Docker & Kubernetes scripts available in `docker/` and `k8s/`.
- **LLM Engine**: Ollama running locally (`mistral:latest`).
- **Database**: MySQL 8.0 with `mysql_config_editor` login paths (`app_reader`, `app_auth`).
- **Frontend Web Interface**: Streamlit (`app.py`).

## 💾 Database Design: Grouped Vertical Partitioning
To bypass InnoDB row limits and optimize for massive data ingestion (~24GB OpenFoodFacts), the database is vertically partitioned:
1. `products_core` (Base data, FULLTEXT indexing)
2. `products_allergens`
3. `products_macros` (Strict `DOUBLE` datatypes)
4. `products_vitamins`
5. `products_minerals`

**CRITICAL NOTE**: The frontend and AI RAG tools interact with a unified `VIEW` named `products` that elegantly `LEFT JOIN`s these partitions.

## 🧠 AI Capabilities & RAG Tools
The Ollama `mistral` model is fully integrated with Streamlit using **Tool Calling**:
- **Tool**: `search_nutrition_db`. The AI can autonomously execute SQL queries against the local database to pull exact nutritional macros.
- **Tool**: `local_web_search`. The AI can anonymously search the web if the DB lacks recipe ideas.
- **Dynamic Profiling**: The Streamlit app extracts the user's EAV health profile and securely injects it into the AI's `sys_prompt`. The AI dynamically acts as a specialized dietitian for that precise condition (e.g., automatically flagging raw meats as forbidden for pregnancy).

## 🚀 Key Features
1. **Dynamic Tabular Analytics**: In the Clinical Search tab, users can click "Ask AI to Evaluate This Table" to grade database rows against their specific illnesses/diets.
2. **Plate Builder & Unit Converter**: `unit_converter.py` parses natural language strings (e.g., "1.5 cups") and converts them to metric grams based on product density.
3. **AI Meal Planner**: Multi-turn RAG loop where the AI queries the database for verified foods before outputting a strict Markdown menu table.
4. **Enterprise Monitoring (Zabbix & SNMPv3)**: A Zabbix stack (`docker/zabbix`) continuously monitors the host, database, and application health. The Python components (`app.py`, `ingest_csv.py`) natively emit encrypted SNMPv3 traps on key events (logins, heavy SQL queries, ingestion milestones).

## 📝 Roadmap History
- **Sprint 1-6 [COMPLETED]**: The project evolved from a foundation into a heavily optimized, vertically partitioned, RAG-integrated medical platform. All code is audited and documentation is finalized in the `docs/` folder.
- **Sprint 7 [ACTIVE]**: SNMPv3 Enterprise Monitoring. Deployed Zabbix Docker containers relying on the host MySQL instance. Injected `pysnmp` logic into core Streamlit and backend workflows for real-time telemetry alerting.
- **Future Work**: The system is in a stable, monitored state. Any future AI agents modifying this project should strictly adhere to the vertical partitioning structure and use `search_nutrition_db` for data fetching.
