## ⚡ The Problem: "Data Chaos"
AI models usually output messy text. If you ask GPT for JSON, it might give you `json` markdown blocks, extra commentary, or missing fields. This breaks downstream applications.

## 🧠 The Solution: Type-Safe Generation
**Structura** is a deterministic extraction engine.
It uses **PydanticAI** to enforce strict schema validation *during* the generation process. If the AI makes a mistake, the framework catches it and auto-corrects before the user ever sees it.

> *"Stop asking the AI to 'be careful'. Force it to be correct."*

## ✨ Key Features

| Feature | Description |
| :--- | :--- |
| **🛡️ Unbreakable JSON** | Outputs are guaranteed to match your Pydantic Models. Zero parsing errors. |
| **🔄 Self-Healing Loop** | If the LLM output fails validation, the agent automatically retries with error context. |
| **⚡ Hyper-Fast UI** | Built with **FastHTML** (HTMX), delivering SPA-like performance without heavy JavaScript frameworks. |
| **🧠 SOTA Intelligence** | Powered by **Gemini 2.5 Flash** (1M Context Window) for processing massive unstructured documents. |
| **📱 Mobile Native** | Lightweight architecture designed to run on Edge devices, Pydroid 3, and Serverless Containers. |

## ⚙️ System Architecture

Structura separates the **Business Logic** (Schemas) from the **AI Logic** (Agents).

### The "SOTA" Stack
*   **Framework:** `PydanticAI` (Validation-First Generation)
*   **Model:** `Gemini 2.5 Flash` (High speed, low cost)
*   **Frontend:** `FastHTML` (Pure Python Web App)
*   **Config:** `YAML` Externalized Prompts
