+# Contributing to dart_dlp
+
+> **Strict Security Protocols in Effect**
+
+Thank you for your interest in `dart_dlp`. This is the world's most performant pure-Dart media engine, and we intend to keep it that way. To maintain the integrity, stability, and security of the codebase, we enforce a strict **Zero-Trust** contribution model.
+
+## 🔒 Security Gatekeeper & CI
+
+We use automated pipelines to vet every line of code before it reaches human review.
+
+### 1. The Security Gatekeeper (`security_check.yml`)
+Every Pull Request triggers the Gatekeeper. It performs the following inspections:
+-   **Static Analysis**: Runs `dart analyze` to ensure 0% linting errors.
+-   **Format Verification**: Runs `dart format --output=none --set-exit-if-changed .` to enforce the Dart style guide.
+
+**If the Gatekeeper fails, your PR is automatically rejected.** Do not waste time asking for a review until the check turns Green.
+
+### 2. The Mass Health Monitor
+We maintain a registry of 1,000+ live test URLs (`test/samples.json`).
+Before submitting a PR, you **MUST** run the health monitor locally:
+
+```bash
+dart run bin/check_health.dart
+```
+
+This script spins up a concurrent engine and tests every single supported site. If your change breaks an unrelated extractor (e.g., your Reddit fix broke YouTube), the monitor will scream in **RED**.
+
+**Do not submit broken code.**
+
+---
+
+## 🚫 Restricted Zones
+
+### The Core (`lib/src/core/`)
+**Status: LOCKED 🔒**
+
+-   **Owner**: @Hamas
+-   **Policy**: No external modifications allowed.
+
+This directory contains the `DlpEngine`, `HamasDownloader`, and `DlpController`. These are finely tuned, high-performance components. Drive-by refactors or "adjustments" to this folder will be closed immediately. If you believe there is a critical bug in the core, open an Issue first.
+
+**Code Owners (`.github/CODEOWNERS`) is configured to enforce this.**
+
+---
+
+## ✅ How to Contribute New Sites
+
+We love new extractors! But you must follow our procedure.
+
+### 1. Use the Factory
+Do not manually copy-paste files. Use our generator tool to create a compliant starting point:
+
+```bash
+dart run bin/hamas_factory.dart <site_name>
+```
+
+This ensures:
+-   Correct File Header (`/// Developed by Hamas`)
+-   Proper Class Naming
+-   Integration with `UserAgentManager`
+-   Inheritance from `BaseExtractor`
+
+### 2. Implementation Rules
+-   **Parsing**: Prefer `JsonScraper` (Regex/JSON) over HTML DOM parsing where possible. DOM parsing is slow and brittle.
+-   **Network**: Always use `headers: {'User-Agent': UserAgentManager.random}` for every request.
+-   **Errors**: Throw clear exceptions (e.g., `SiteNotSupportedException`, `AccountPrivateException`).
+
+### 3. Register It
+-   Add your new extractor export to `lib/dart_dlp.dart`.
+-   Add a test URL to `test/samples.json`.
+
+---
+
+## 📜 Branch & Edit Policy
+
+**Direct pushes to `main` are disabled for everyone.**
+**Editing Documentation is Restricted.**
+
+1.  **Fork** the repository.
+2.  Create a **Feature Branch** (e.g., `feat/add-vimeo`).
+3.  **Commit** your changes.
+4.  Open a **Pull Request**.
+
+> **Note**: Do not attempt to modify `README.md`, `CONTRIBUTING.md`, or `.github/CODEOWNERS`. These files are locked to the Owner (@Hamas) only.
+
+Your code belongs to us now.

+
+---
+
+## 📖 Introduction
+
+**dart_dlp** is a revolutionary media extraction engine designed to liberate Dart and Flutter developers from the constraints of heavy external binaries. Unlike traditional solutions that wrap `yt-dlp` (Python) or require massive `ffmpeg` bundles, `dart_dlp` is built from the ground up to be **Lightweight and Invincible**.
+
+It combines a **Pure Dart** extraction core with a **Native (Kotlin/Swift)** muxing bridge, delivering 8K video streams without a single byte of compiled FFmpeg or Python code.
+
+It is engineered for **Hyper-Scale** and **Stealth**, capable of navigating complex anti-bot protections and executing rolling cipher decryption.
+
+---
+
+### Why dart_dlp?
+
+1.  **Zero External Binaries**: No Python, no node.js.
+2.  **Native Muxing**: Uses Android's `MediaMuxer` and iOS's `AVAssetExportSession` to merge 4K video+audio instantly (Zero-Encoding).
+3.  **HamasDownloader™**: A proprietary, multi-threaded chunked downloader that saturates your bandwidth by opening parallel connections.
+4.  **Stealth Mode**: Rotates between 50+ real-world User-Agents and injects human-like HTTP headers (`Sec-Fetch-*`) to evade IP blocking.
+5.  **Architecture**: Decoupled design allows for pure Dart usage (extraction only) or full Flutter Plugin power (muxing enabled).
+
+---
+
+## ⚙️ Advanced Features
+
+### ⚡ HD Download & Native Muxing (The "Super" Pattern)
+YouTube (and others) often serve 1080p+ video as separate Video and Audio tracks.
+`dart_dlp` handles this automatically using its Native Bridge.
+
+**Zero-FFmpeg Requirement:**
+We utilize the device's native APIs (`MediaMuxer` on Android, `AVAssetExportSession` on iOS) to merge streams instantly without re-encoding. This keeps the app size tiny only adding ~20KB to your bundle, compared to FFmpeg's ~50MB.
+
+**How it works:**
+1.  **Detects** if a video is split (e.g., 4K stream).
+2.  **Downloads** video and audio tracks concurrently.
+3.  **Invokes** the Native Bridge to merge them in seconds.
+4.  **Cleans up** temporary files.
+
+```dart
+final controller = DlpController();
+
+// 1. Get Video Data
+final videoData = await engine.extract('https://tiktok.com/...');
+
+// 2. Start Download (Auto-Muxing handled internally)
+controller.state.listen((state) {
+  if (state.status == DlpStatus.downloading) {
+    print('Downloading... ${state.progress?.percentage.toStringAsFixed(1)}%');
+  } else if (state.status == DlpStatus.completed) {
+    print('Done! File at: ${state.message}');
+  }
+});
+
+await controller.startDownload(videoData, '/downloads/');
+final path = await controller.startDownload(videoData, '/storage/emulated/0/Download');
+print('Saved to: $path');
+```
+
+---
+
+## 🛡️ Stealth Technology
+
+To ensure longevity, `dart_dlp` mimics human behavior.
+
+1.  **User-Agent Rotation**: Every request pulls from a library of 50+ modern User-Agents (Chrome, Firefox, Safari on Windows, Mac, Linux).
+2.  **Request Factory**: We inject trusted headers (`Sec-Fetch-Mode: navigate`, `Sec-Fetch-Site: none`) to bypass "naive" bot filters.
+3.  **Proxy Injection**: Support for residential proxies via the `proxy` parameter allows for massive scraping operations (100k+ requests/day).
+
+---
+
+## 🔮 Extending dart_dlp
+
+We built a factory tool so you can add support for new sites in seconds.
+
+### The Hamas Factory
+Use the CLI tool to generate a new extractor template. This ensures your code complies with our strict architectural standards.
+
+```bash
+dart run bin/hamas_factory.dart my_new_site
+```
+
+**Output:** `lib/src/extractors/my_new_site_extractor.dart`
+
+This file comes pre-loaded with:
+- `/// Developed by Hamas` header.
+- `JsonScraper` mixin.
+- Correct `canHandle` and `extract` signatures.
+
+---
+
+## ⚠️ Disclaimer
+**dart_dlp** is an educational tool designed for interoperability and data portability. Use this engine responsibly and respect the Terms of Service of the platforms you interact with.
+
+---
+
+## 🔒 Strict Ownership & Security
+**dart_dlp** is protected by a strict security policy. 
+
+-   **Owner-Only Access**: Only the repository creator (@Hamas) is authorized to approve changes, merge Pull Requests, or modify the repository configuration.
+-   **Documentation Locked**: The `README.md` and `CONTRIBUTING.md` files define the laws of this repository. **No one else is permitted to edit, alter, or dilute these rules.** Any Pull Request attempting to modify these files without explicit prior authorization will be closed and the user blocked.
