Subject: [PATCH 1/4] feat: add comprehensive repository structure

Adds standard research repository directories (`docs`, `scripts`,
`notebooks`, `data`, `models`, `results`, `configs`, `references`)
and populates them with 20+ relevant, well-structured files such
as stubs, notebooks, configuration files, and theoretical documentation,
without altering any existing repository contents.

+# System Architecture
+
+## Core Modules
+1. **`AnTiEnTRopY.py`**: The main Streamlit orchestrator. Handles file uploads, parameters, and tab rendering.
+2. **`EnTRopY.py`**: Calculates Shannon entropy, Methylation Order Index (MOI), and identifies drifting CpGs.
+3. **`CloCk.py`**: Implements an ElasticNet-based biological age predictor.
+4. **`HRF_EpIgEnEtIc.py`**: A novel classifier using a Harmonic Resonance Field (HRF) approach and Fast Fourier Transform for spectral analysis.
+5. **`ReVeRsAL.py`**: Simulates partial epigenetic reprogramming by shifting high-drift CpGs towards young reference values.
+6. **`ImMoRtAlItY.py`**: Uses Monte Carlo simulations to model the conditions for "epigenetic escape velocity."
+
+## Data Flow
+Upload -> Preprocessing -> Clock Training -> Entropy Calculation -> HRF Classification -> Reversal Simulation -> Monte Carlo Projections -> Research Report Generation.

+# Installation Guide
+
+## Prerequisites
+- Python 3.9+
+- pip (Python package manager)
+
+## Steps
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/Devanik21/AnTiEnTRopY.git
+   cd AnTiEnTRopY
+   ```
+
+2. (Optional but recommended) Create a virtual environment:
+   ```bash
+   python -m venv venv
+   source venv/bin/activate  # On Windows: venv\Scripts\activate
+   ```
+
+3. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+## Using Docker
+A `docker-compose.yml` is provided for containerized deployment:
+```bash
+docker-compose up --build
+```

+# Mathematical Framework
+
+This document details the mathematical models underlying the AnTiEnTRopY engines.
+
+## 1. Epigenetic Entropy
+The site-wise informational disorder is quantified by the binary Shannon entropy:
+$H(\beta) = -\beta \log_2(\beta) - (1-\beta) \log_2(1-\beta)$
+
+## 2. Harmonic Resonance Field (HRF)
+The resonance energy for class c is given by:
+$E_c(\mathbf{q}) = \sum_{i=1}^{k} \exp(-\gamma\|\mathbf{q} - \mathbf{x}^{(c)}_i\|_2^2) \cdot (1 + \cos(\omega_c\|\mathbf{q} - \mathbf{x}^{(c)}_i\|_2))$
+
+## 3. Escape Velocity Condition
+The system is at epigenetic escape velocity when the net biological age change per cycle is negative or zero:
+$\Delta a_{\text{net}}(p, T) = T - R(p) \le 0$

+# User Manual
+
+## Overview
+AnTiEnTRopY is an interactive Streamlit application. It takes a CSV of DNA methylation beta values and chronological ages, and outputs a suite of analyses across 6 main tabs.
+
+## Preparing Data
+Your input CSV must contain:
+1. An `age` column (chronological age in years).
+2. CpG site columns (e.g., `cg00000029`), where values are between 0 and 1.
+
+## Navigation
+1. **Upload Data:** Use the sidebar to upload your CSV file.
+2. **Parameters:** Adjust parameters such as top-K CpGs for the clock or intervention percentage.
+3. **Tabs:** Navigate through Biological Clock, Epigenetic Entropy, HRF Classifier, Reversal Simulator, Immortality Engine, and the Research Report to view different analyses.

+# Literature Review
+
+## Epigenetic Clocks
+The seminal works of Horvath (2013) and Hannum (2013) established that DNA methylation status at a select few hundred CpG sites can predict chronological age with high accuracy. The discrepancy between predicted and actual age, known as epigenetic age acceleration, correlates strongly with mortality and age-related disease.
+
+## Partial Reprogramming
+Ocampo et al. (2016) demonstrated that transient expression of the Yamanaka factors (OSKM) can reverse cellular aging phenotypes without causing a complete loss of cell identity. This finding supports the notion that aging is a reversible, epigenetic phenomenon rather than simply the accumulation of irreversible DNA damage.
+
+## Information Theory of Aging
+Proposed by Sinclair and others, this theory posits that aging is fundamentally a loss of epigenetic information. Entropy increases over time, causing a noisification of the methylome. AnTiEnTRopY formalizes this by applying Shannon entropy to methylation beta values.
