Feat: Integrated Local LLM (Llama 3.2 1B) for Intelligent Correction -- New Core: Added LLMEngine utilizing llama-cpp-python for local private text post-processing. -- Forensic Protocol: Engineered strict system prompts to prevent LLM refusals, censorship, or assistant chatter. -- Three Modes: Grammar, Standard, Rewrite. -- Start/Stop Logic: Consolidated conflicting recording methods. -- Hotkeys: Added dedicated F9 (Correct) vs F8 (Transcribe). -- UI: Updated Settings. -- Build: Updated portable_build.py. -- Docs: Updated README.

- Added robust CPU Fallback for AMD/Non-CUDA GPUs.
- Implemented Lazy Load for AI Engine to prevent startup crashes.
- Added explicit DLL injection for Cublas/Cudnn on Windows.
- Added Corrupt Model Auto-Repair logic.
- Includes pre-compiled v1.0.4 executable.

 ### Workflow: `F9 (Default)`
 The primary channel for native-language transcription. It transcribes precisely what it hears in the language you speak (or the one you've locked in Settings).
 
-### ✨ Style Prompting (New in v1.0.2)
+### 🧠 Intelligent Correction (New in v1.1.0)
-Whisper Voice replaces traditional "grammar correction models" with a native **Style Prompting** engine. By injecting a specific "pre-prompt" into the model's context window, we can guide its internal style without external post-processing.
+Whisper Voice now integrates a local **Llama 3.2 1B** LLM to act as a "Silent Consultant". It post-processes transcripts to fix grammar or polish style without effectively "chatting" back. 
 
-*   **Standard (Default)**: Forces the model to use full sentences, proper capitalization, and periods. Ideal for dictation.
+It is strictly trained on a **Forensic Protocol**: it will never lecture you, never refuse to process explicit language, and never sanitize your words. Your profanity is yours to keep.
-*   **Casual**: Encourages a relaxed, lowercase style (e.g., "no way that's crazy lol").
-*   **Custom**: Allows you to seed the model with your own context (e.g., "Here is a list of medical terms:").
 
-This approach incurs **zero latency penalty** and **zero extra VRAM** usage.
+#### Correction Modes:
+*   **Standard (Default)**: Fixes grammar, punctuation, and capitalization while keeping every word you said.
+*   **Grammar Only**: Strictly fixes objective errors (spelling/agreement). Touches nothing else.
+*   **Rewrite**: Polishes the flow and clarity of your sentences while explicitly preserving your original tone (Casual stays casual, Formal stays formal).
+
+#### Supported Languages:
+The correction engine is optimized for **English, German, French, Italian, Portuguese, Spanish, Hindi, and Thai**. It also performs well on **Russian, Chinese, Japanese, and Romanian**.
+
+This approach incurs a ~2s latency penalty but uses **zero extra VRAM** when in Low VRAM mode.

-# Release v1.0.2
+# Release v1.0.4
 
-**"The Lightweight Release"**
+**"The Compatibility Update"**
 
-This release focuses on removing bloat and switching to a native approach for punctuation, resulting in a significantly faster and smaller application.
+This release focuses on maximum stability across different hardware configurations (AMD, Intel, Nvidia) and fixing startup crashes related to corrupted models or missing drivers.
 
-## 🚀 Key Changes
+## 🛠️ Critical Fixes
 
-### 1. Style Prompting (Replaces Grammar Model)
+### 1. Robust CPU Fallback (AMD / Intel Support)
-We have removed the heavy "Grammar Correction" model (M2M100) and replaced it with **Style Prompting**.
+*   **Problem**: Previously, if an AMD user tried to run the app, it would crash instantly because it tried to load Nvidia CUDA libraries by default.
-*   **How it works**: Uses Whisper's internal context awareness to force proper punctuation.
+*   **Fix**: The app now **silently detects** if CUDA initialization fails (due to missing DLLs or incompatible hardware) and **automatically falls back to CPU mode**.
-*   **New Settings**: Go to `Settings -> AI Engine` to choose a style:
+*   **Result**: The app "just works" on any Windows machine, regardless of GPU.
-    *   **Standard**: (Default) Forces full sentences and proper punctuation.
-    *   **Casual**: Relaxed, lowercase style.
-    *   **Custom**: Enter your own prompt context.
 
-### 2. Bloat Removal
+### 2. Startup Crash Protection
-*   **Removed**: `transformers`, `sentencepiece`, `accelerate` libraries.
+*   **Problem**: If `faster_whisper` was imported before checking for valid drivers, the app would crash on launch for some users.
-*   **Removed**: `grammar-m2m100` model downloader and logic.
+*   **Fix**: Implemented **Lazy Loading** for the AI engine. The app now starts the UI first, and only loads the heavy AI libraries inside a safety block that catches errors.
-*   **Impact**: The application is lighter, installs faster, and uses less RAM.
 
-### 3. Stability Fixes
+### 3. Corrupt Model Auto-Repair
-*   **Fixed**: `NameError: 'torch' is not defined` when using Low VRAM Mode.
+*   **Problem**: Interrupted downloads could leave a corrupted model folder, preventing the app from ever starting again.
-*   **Fixed**: Bootstrapper now self-repairs missing dependencies if the environment gets corrupted.
+*   **Fix**: If the app detects a "vocabulary missing" or invalid config error, it will now **automatically delete the corrupt folder** and allow you to re-download it cleanly.
+
+### 4. Windows DLL Injection
+*   **Fix**: Added explicit DLL path injection for `nvidia-cublas` and `nvidia-cudnn` to ensure Python 3.8+ can find the required CUDA libraries on Windows systems that don't have them in PATH.
