%   SECTION 1: INTRODUCTION
% =======================================================================================
\setsectioncolor{IntroColor}
\section{Introduction to Warlock-Studio v5.0}
Welcome to Warlock-Studio v5.0 — a major evolutionary leap in AI-powered media enhancement.
This version introduces a robust \textbf{Modular Architecture} and the new \textbf{NEO Engine}, optimizing
stability, hardware diagnostics, and processing efficiency. It provides advanced tools for super-resolution,
artifact removal, and frame generation through an intuitive interface that now includes an \textbf{Integrated Console}
and native \textbf{Drag \& Drop} support.

% =======================================================================================
%   SECTION 2: QUICK START GUIDE
% =======================================================================================
\setsectioncolor{QuickStartColor}
\section{Quick Start Guide}
\begin{quickstartbox}{Accelerated Media Enhancement Procedure}
Follow these steps to process your media using the new v5.0 workflow.
\begin{enumerate}
    \item \textbf{Load Files (Drag \& Drop):} You can now simply \textbf{drag and drop} your image or video files directly onto the application window. Alternatively, click the \textbf{"Select Files"} button.
    \item \textbf{AI Model Selection:} In the \textbf{"AI model"} dropdown menu, select an inference model.
    \begin{itemize}
        \item For photorealistic images, \inlinecode{BSRGANx4} is recommended for texture reconstruction.
        \item For animation/cartoons, \inlinecode{RealESR_Animex4} preserves sharp edges.
        \item For video, \inlinecode{RealESR_Gx4} balances speed and quality.
        \item For increasing framerate, use \inlinecode{RIFE} models (note: Blending controls will hide automatically).
    \end{itemize}
    \item \textbf{Verify Hardware (NEO Engine):} Click the \textbf{Gear Icon} (\faCog) to open Preferences. Check the \textbf{Hardware Diagnostics} to see the "Recommended Tiles" and "Safe VRAM Limit" calculated specifically for your PC.
    \item \textbf{Adjust Settings:} Set the \textbf{"GPU VRAM (GB)"} based on the recommendation. For a quick test, set \textbf{"Input resolution"} to \texttt{75}\%.
    \item \textbf{Start Processing:} Click \textbf{"Make Magic"}. You can now monitor real-time progress and logs via the new \textbf{Integrated Console} at the bottom of the window.
\end{enumerate}
\end{quickstartbox}

%   SECTION 3: INSTALLATION & ARCHITECTURE
% =======================================================================================
\setsectioncolor{InstallColor}
\section{Installation and Modular Architecture}
\subsection{\faDownload\ Installation Process \& Path Change}
Warlock-Studio uses a self-contained offline installer.

\begin{warnbox}{Critical: Installation Directory Change}
In version 5.0, the default installation directory has been migrated from \texttt{Program Files} to:
\begin{center}
\inlinecode{\%userprofile\%\\Documents\\Warlock-Studio}
\end{center}
\textbf{Reason:} This change prevents "Permission Denied" errors on Windows systems with strict UAC. It ensures the application has full read/write access to generate the \inlinecode{warlock_config.json}, write real-time logs, and manage video checkpoints without requiring constant Administrator privileges.
\end{warnbox}

\begin{enumerate}[leftmargin=*]
    \item \textbf{Obtaining the Executable:} Download the `Warlock-Studio-Setup.exe` (Full Installer) from the official repositories.
    \item \textbf{Run the Installer:} Run the setup. It will automatically default to your Documents folder.
    \item \textbf{Launch:} Open Warlock-Studio via the Desktop shortcut.
\end{enumerate}

\subsection{\faMicrochip\ System Requirements}
\begin{table}[H]
    \centering
    \begin{tabularx}{\textwidth}{lX}
        \toprule
        \textbf{Component} & \textbf{Technical Specification} \\
        \midrule
        Operating System & Windows 11 or Windows 10 (64-bit architecture required). \\
        RAM & 8 GB (minimum), 16 GB (recommended). \\

        & \textbf{AMD/Intel:} DirectML support. \\
        & \textbf{4+ GB of VRAM} is recommended. \\
        Storage & 2 GB of free disk space. SSD strongly recommended for video I/O. \\
        \bottomrule
    \end{tabularx}
    \caption{Requirements for v5.0. The NEO Engine will verify these upon launch.}
\end{table}

\subsection{\faPuzzlePiece\ Modular File Architecture (v5.0)}
\begin{infobox}{From Monolithic to Modular}
Version 5.0 abandons the single-script structure. The application is now composed of specialized modules to improve stability and maintainability.
\end{infobox}

\begin{itemize}[leftmargin=*]
    \item \textbf{\inlinecode{Warlock-Studio.py} (Core Orchestrator):}
    Manages the main GUI event loop and spawns multiprocessing tasks for AI inference.
    \item \textbf{\inlinecode{warlock_preferences.py} (State Manager):}
    Houses the \textbf{NEO Engine} for hardware telemetry, the \inlinecode{ConfigManager} for JSON persistence, and the OTA Update Manager.
    \item \textbf{\inlinecode{console.py} (I/O Manager):}
    Controls the new \textbf{Integrated Console}, redirecting \texttt{stdout} and \texttt{stderr} streams to the GUI for real-time debugging.
    \item \textbf{\inlinecode{drag_drop.py} (Event Wrapper):}
    Implements the \inlinecode{DnDCTk} class to handle native OS Drag \& Drop events.
    \item \textbf{Assets:}
    Includes \inlinecode{ffmpeg.exe}, \inlinecode{exiftool.exe}, and the AI Models (`.onnx`) in the \texttt{AI-onnx} directory.

\setsectioncolor{OptimizeColor}
\section{Performance Optimization and NEO Engine}

\subsection{\faMagic\ The NEO Engine}
\begin{neobox}{Automatic Hardware Heuristics}
Warlock-Studio v5.0 introduces the \textbf{NEO Engine} (located in \inlinecode{warlock_preferences.py}). This system scans your CPU, RAM, and GPU capabilities in real-time to generate \textbf{Smart Recommendations}.
\end{neobox}

\begin{itemize}[leftmargin=*, itemsep=2pt]
    \item \textbf{Safe VRAM Limit:} The engine calculates a safe buffer using the formula: $\max(0.5, \text{Physical VRAM} - 1.5 \text{ GB})$.
    \item \textbf{Recommended Tiles:} It suggests the optimal \inlinecode{tiles_resolution} to maximize speed while preventing Out-Of-Memory (OOM) crashes.
    \item \textbf{Thread Concurrency:} It analyzes your CPU topology (physical vs. logical cores) to suggest safe multithreading levels for video processing.
\end{itemize}

\subsection{\faSlidersH\ Critical Parameters}
\begin{itemize}[leftmargin=*, itemsep=2pt]
    \item \textbf{Input Resolution \%:} Setting this to \textbf{75\%} drastically reduces load with minimal quality loss.
    \item \textbf{AI Multithreading:} (Video only) Processes multiple frames in parallel. Use the NEO Engine's recommendation to avoid system freezing.
    \item \textbf{Keep Frames:} Enable this (\inlinecode{selected_keep_frames = True}) if you plan to experiment with different video encoding codecs later.
\end{itemize}

% =======================================================================================
%   SECTION 6: TROUBLESHOOTING
% =======================================================================================
\setsectioncolor{TroubleColor}
\section{Diagnostics and Troubleshooting}
\begin{warnbox}{Integrated Console}
Use the new **Integrated Console** at the bottom of the app window to view real-time error logs, warnings, and processing status. You can search, copy, and save these logs.
\end{warnbox}

\begin{description}[leftmargin=*, style=nextline, itemsep=0.8em]
    \item[\faBan\ Error: "FFmpeg encoding failed..." / Fallback Active]
        \textbf{Diagnosis:} The selected hardware codec (e.g., \inlinecode{hevc_nvenc}) failed due to driver issues or resource locking.
        \textbf{v5.0 Solution:} The system now features an \textbf{Automatic Fallback}. If the GPU encoder fails, it automatically switches to the CPU-based \inlinecode{libx264} encoder to ensure the video is finished. Check the console for yellow warnings indicating this switch.

    \item[\faMemory\ Error: "Out of memory" / OOM Recovery]
        \textbf{Diagnosis:} VRAM exhaustion during tiling.
        \textbf{v5.0 Solution:} The application detects this exception and triggers \textbf{Recursive Dynamic Tiling}. It automatically halves the tile resolution (e.g., 100\% $\to$ 50\%) and retries the frame. You do not need to restart the process manually.

    \item[\faRocket\ Error: "Failed to load model" (ONNX)]
        \textbf{Diagnosis:} Issue initializing the execution provider.
        \textbf{Solution:} v5.0 implements a strict priority chain: CUDA $\to$ DirectML $\to$ CPU. Ensure your GPU drivers are up to date. If using an older NVIDIA card, the system may default to DirectML or CPU.

    \item[\faTachometerAlt\ Error: "NaN" (Not a Number)]
        \textbf{Diagnosis:} GPU Driver Timeout (TDR).
        \textbf{Solution:} Restart the process without deleting the temp frames folder. The app will resume from the last successful frame.

% =======================================================================================
\setsectioncolor{ArchColor}
\section{Software Architecture Analysis (v5.0)}

\subsection{\faCogs\ Modular Inference Engine}
Warlock-Studio v5.0 utilizes a robust \textbf{ONNX Runtime} backend managed by the \inlinecode{create_onnx_session} factory in the core orchestrator. It enforces strict integer typing for device IDs to ensure compatibility with rigid DirectML backends.

\subsection{\faSyncAlt\ Lossless Intermediate Pipeline}
In v5.0, the video extraction pipeline (\inlinecode{extract_video_frames}) strictly enforces the use of \textbf{.PNG} containers for temporary frames. This eliminates the generation loss previously caused by JPEG artifacts before the image entered the neural network.

\subsection{\faThLarge\ Architecture Diagram (Modular)}
