chore: Remove redundant GRAG sampler, update to v2.4.1

## Package Cleanup
- Removed nodes/sampling/archai3d_grag_sampler.py (now in separate GRAG repo)
- Removed GRAG sampler import and registration from __init__.py
- Updated startup message to reference separate GRAG package

## Retained GRAG Utilities
- GRAG Modifier (conditioning metadata injection)
- GRAG Encoder (Qwen encoder with GRAG support)
- These utility nodes work with the separate GRAG Advanced Sampler

## Version
- Updated version to 2.4.1
- Added SESSION_UPDATES_v2.4.1.md documentation

## Rationale
The full GRAG Advanced Sampler is maintained in the separate repository:
https://github.com/amir84ferdos/ComfyUI-GRAG-ArchAi3D

This keeps packages focused:
- ComfyUI-ArchAi3d-Qwen: Camera control + Qwen encoding
- ComfyUI-GRAG-ArchAi3D: Advanced GRAG sampling with 54 presets

+# Auto-Facing Feature Documentation
+
+## Overview
+
+The `auto_facing` parameter ensures the camera automatically points directly at the target subject from any horizontal angle position. This feature is now available in both **Object Focus Camera v7** and **Cinematography Prompt Builder**.
+
+---
+
+## Purpose
+
+When positioning the camera at angles (left, right, side, back), `auto_facing` controls whether the camera:
+- ✅ **Points directly at the subject** (auto_facing = True)
+- ❌ **Maintains forward orientation** without explicitly facing the subject (auto_facing = False)
+
+---
+
+## Implementation Details
+
+### Parameter Specification
+
+```python
+"auto_facing": ("BOOLEAN", {
+    "default": True,
+    "tooltip": "Automatically face camera toward target subject (recommended for object photography).\n"
+               "• True = Camera points directly at subject from chosen angle\n"
+               "• False = Camera positioned at angle but may not face subject directly"
+})
+```
+
+### Prompt Positioning Strategy
+
+**Key Finding**: Based on user experience with vision-language models, placing `auto_facing` guidance **at the beginning of the prompt** provides maximum attention weight and effectiveness.
+
+**Prompt Structure:**
+
+```
+[FACING DIRECTIVE] + [Main Camera Prompt] + [Details]
+```
+
+**Examples:**
+
+#### Simple Prompt (English):
+```
+Facing the dishwasher directly, An eye-level medium shot of the dishwasher, taken from a vantage point two meters away, positioned from thirty degrees to the left for a corner perspective, with deep depth of field keeping everything in focus, in architectural style
+```
+
+#### Professional Prompt (Chinese):
+```
+面对dishwasher，Next Scene: 将镜头转为标准镜头(50mm)，中景构图，平视查看dishwasher，从左侧30度拍摄,呈现转角视角，距离两米
+```
+
+---
+
+## When Auto-Facing Is Applied
+
+### ✅ Active Conditions:
+- `auto_facing = True` (default)
+- `horizontal_angle != "Front View (0°)"` (since front view already implies facing)
+
+### ❌ Not Applied When:
+- `auto_facing = False`
+- `horizontal_angle = "Front View (0°)"` (redundant - front view inherently faces subject)
+
+---
+
+## Usage Examples
+
+### Example 1: Dishwasher Side View with Auto-Facing
+
+**Settings:**
+- Target Subject: `dishwasher`
+- Shot Type: `Medium Shot (MS)`
+- Camera Angle: `Eye Level`
+- Horizontal Angle: `Side Left (90°)`
+- **auto_facing: `True`** ✅
+
+**Result:**
+Camera positions at the left side (90°) AND rotates to face the dishwasher directly, ensuring the dishwasher is centered in frame despite the side positioning.
+
+---
+
+### Example 2: Architectural Context Shot without Auto-Facing
+
+**Settings:**
+- Target Subject: `kitchen counter`
+- Shot Type: `Wide Shot (WS)`
+- Camera Angle: `Eye Level`
+- Horizontal Angle: `Angled Right 30°`
+- **auto_facing: `False`** ❌
+
+**Result:**
+Camera positions at 30° to the right but maintains forward orientation, potentially showing the counter as part of a broader environmental context rather than centered.
+
+---
+
+## Technical Implementation
+
+### Cinematography Prompt Builder
+
+#### Simple Prompt Generation ([cinematography_prompt_builder.py:685-688](nodes/camera/cinematography_prompt_builder.py#L685-L688)):
+
+```python
+# AUTO-FACING: Add at the VERY BEGINNING for maximum attention weight
+# Only add if enabled AND not front view (front view already implies facing)
+if auto_facing and horizontal_angle != "Front View (0°)":
+    parts.append(f"Facing {subject} directly")
+```
+
+#### Professional Prompt Generation ([cinematography_prompt_builder.py:757-763](nodes/camera/cinematography_prompt_builder.py#L757-L763)):
+
+```python
+# AUTO-FACING: Add at BEGINNING for maximum attention (before "Next Scene:")
+# Only add if enabled AND not front view
+if auto_facing and horizontal_angle != "Front View (0°)":
+    if language in ["Chinese (Best for dx8152 LoRAs)", "Hybrid (Chinese + English)"]:
+        prompt_parts.append(f"面对{subject}")  # "Facing {subject}"
+    else:
+        prompt_parts.append(f"Facing {subject} directly")
+```
+
+---
+
+## Why Positioning Matters
+
+### User Observation:
+> "i know it is important if you merg it to prompt at begiing it will have more affect base on my experince"
+
+This aligns with attention mechanisms in transformer-based vision-language models:
+
+1. **Positional Bias**: Tokens at the beginning of prompts receive higher attention weights
+2. **Semantic Anchoring**: Early instructions establish the primary directive for the generation
+3. **Context Precedence**: Models process sequential information with recency and primacy effects
+
+By placing `auto_facing` directive **first**, we ensure maximum model attention to this critical orientation instruction.
+
+---
+
+## Integration with Other Features
+
+### Compatible with:
+- ✅ All horizontal angles (15°, 30°, 45°, 90°, 180°)
+- ✅ All vertical camera angles (Eye Level, High Angle, Low Angle, etc.)
+- ✅ All shot sizes (ECU to EWS)
+- ✅ Perspective correction modes (Natural, Architectural, Tilt-Shift)
+- ✅ All lens types
+- ✅ Chinese/English/Hybrid language modes
+
+### Automatically Disabled:
+- Front View (0°) - redundant since front view inherently faces subject
+- When explicitly disabled by user (`auto_facing = False`)
+
+---
+
+## Practical Use Cases
+
+### 🎯 Object Photography (Recommended: True)
+- Product photography requiring subject prominence
+- Furniture visualization from multiple angles
+- Appliance close-ups (dishwashers, ovens, refrigerators)
+- Detail shots of architectural elements
+
+### 🏛️ Environmental Photography (Consider: False)
+- Architectural context shots
+- Room overview with subject as part of environment
+- Documentary-style environmental capture
+- Spatial relationship emphasis over subject focus
+
+---
+
+## Version History
+
+- **v2.4.1** (2025-01-07): Added `auto_facing` to Cinematography Prompt Builder
+  - Placed at beginning of prompts for maximum attention weight
+  - Full Chinese translation support (面对)

+
+## Key Improvements
+
+### 1. Auto-Facing Placement
+**Before:** Not available in Cinematography Prompt Builder
+**After:** Added at the BEGINNING of prompts for maximum attention weight
+
+**User Insight:** "i know it is important if you merg it to prompt at begiing it will have more affect base on my experince"
+
+This placement leverages positional bias in vision-language models.
+
+---
+
+### 2. Distance Chinese Precision
+
+**Before:**
+```
+距离远距离  (distance far distance) ❌ Generic, redundant
+距离中等距离 (distance medium distance) ❌ Vague
+```
+
+**After:**
+```
+距离四米 (distance 4 meters) ✅ Specific
+距离两米半 (distance 2.5 meters) ✅ Precise with half meters
+距离零点八米 (distance 0.8 meters) ✅ Handles decimals
+```
+
+**Chinese Number Mapping:**
+- Whole numbers: 一米, 两米, 三米, 四米, etc.
+- Half meters: 半米, 一米半, 两米半, etc.
+- Decimals: 零点八米, 两点五米, etc.
+
+---
+
+### 3. English Mode Bug Fix
+
+**Issue:** Professional English prompts were bypassing the auto_facing logic
+
+**Before:**
+```
+Next Scene: Change to Normal (50mm), MS framing... ❌ Missing "Facing" clause
+```
+
+**After:**
+```
+Facing the refrigerator directly, Next Scene:, Change to Normal (50mm), MS framing... ✅
+```
+
+**Fix:** Updated English mode code path to include `prompt_parts` with auto_facing directive
+
+---
+
+## Auto-Facing Logic
+
+### When Active:
+- ✅ `auto_facing = True` (default)
+- ✅ `horizontal_angle != "Front View (0°)"`
+
+### When Inactive:
+- ❌ `auto_facing = False` (user disabled)
+- ❌ `horizontal_angle = "Front View (0°)"` (redundant - front view already faces subject)
+
+---
+
+## Language Support
+
+### Chinese Mode:
+```
+面对{subject} Next Scene: ...
+```
+
+### English Mode:
+```
+Facing {subject} directly, [prompt]...
+```
+
+### Hybrid Mode:
+```
+面对{subject} Next Scene: ... (Chinese cinematography + English details)
+```
+
+---
+
+## Integration Status
+
+✅ **Cinematography Prompt Builder** - Fully integrated
+✅ **Object Focus Camera v7** - Already had auto_facing
+✅ **Simple Prompt Generation** - Working
+✅ **Professional Prompt Generation** - Working (bug fixed)
+✅ **All Language Modes** - Working (Chinese/English/Hybrid)
+
+---
+
+## Files Modified
+
+1. **cinematography_prompt_builder.py**

+
+## User Confirmation
+
+User prompt example:
+```
+Next Scene: 将镜头转为标准镜头(50mm)，全景构图，平视查看the refrigerator ，距离远距离
+```
+
+**Issues identified and fixed:**
+1. ❌ No auto_facing clause → ✅ "面对" added when using angled views
+2. ❌ "距离远距离" (distance far distance) → ✅ "距离四米" (distance 4 meters)
+3. ❌ Mixed language "the refrigerator" → Still present but acceptable for Hybrid mode
+
+**Recommendations for user:**
+- Use Chinese subject name "冰箱" OR keep "the refrigerator" (both work)
+- Select angled horizontal angles (15°, 30°, 45°, 90°) to activate auto_facing
+- Default `auto_facing = True` ensures camera points at subject
+

+[Images] → [Encoder V2] → [GRAG Modifier] → [GRAG Sampler] → [VAE Decode] → [Output]
+                               ↓ enable_grag=True      ↓ Applies reweighting
+                          Prepares metadata
+```
+
+**Important**: Standard KSampler will NOT apply GRAG effects, even if GRAG Modifier is used!
+
+---
+
 ## [2.1.1] - 2025-11-03
 
+### Added
+- **GRAG Modifier Node** (Recommended - Universal):
+  - New `ArchAi3D GRAG Modifier` - Universal conditioning modifier
+  - Works with ANY encoder (V1, V2, V3, Simple, etc.)
+  - Clean passthrough mode when disabled (optional use)
+  - Perfect for A/B testing and flexible workflows
+  - **Benefits**: No code duplication, maximum flexibility, easy maintenance
+
+- **GRAG Encoder Node** (Experimental - Standalone):
+  - `ArchAi3D Qwen GRAG Encoder` - Standalone GRAG encoder
+  - Includes full encoder + GRAG in one node
+  - Useful for testing GRAG-specific configurations
+  - May be deprecated in favor of modifier approach
+
+- **GRAG Implementation**:
+  - Implements GRAG (Group-Relative Attention Guidance) metadata preparation
+  - Three main parameters: `grag_strength` (0.8-1.7), `grag_cond_b`, `grag_cond_delta`
+  - Adjustable in 0.01 increments for precise control
+  - Better structure/window preservation potential
+  - Training-free fine-grained editing control
+
+- **GRAG Documentation**:
+  - Complete usage guide with parameter explanations
+  - Integration examples with Clean Room workflow
+  - Parameter tuning tips and troubleshooting
+  - Future development roadmap
+  - Comparison: Modifier vs Encoder approaches
+
 ### Changed
 - Updated version number to 2.1.1 for proper release tracking
+- Increased encoder count from 5 to 6 nodes
+- Updated startup message to highlight GRAG feature
+
+### Technical Notes
+- Current GRAG implementation is a **placeholder** preparing metadata

+# Cinematography Prompt Builder - Complete Implementation Summary
+
+## Overview
+
+Complete implementation of the Cinematography Prompt Builder node based on **Nanobanan's 5-ingredient camera prompting formula**, incorporating research-validated best practices and working examples.
+
+**Implementation Date:** 2025-01-06
+**Version:** v2.4.0 (pending release)
+**Author:** Amir Ferdos (ArchAi3d)
+
+---
+
+## What Was Implemented
+
+### ✅ 1. System Prompt Addition
+**File:** [nodes/camera/cinematography_prompt_builder.py](nodes/camera/cinematography_prompt_builder.py)
+**Documentation:** [SYSTEM_PROMPT_UPDATE.md](SYSTEM_PROMPT_UPDATE.md)
+
+**Changes:**
+- Updated `RETURN_TYPES` from 3 to 4 outputs (added `system_prompt`)
+- Added `_get_cinematography_system_prompt()` method with **3 intelligent variants**:
+  - **Simple/Beginner Mode** (default): Focuses on Nanobanan's 5 ingredients
+  - **Professional Mode** (Chinese + presets): dx8152 LoRA optimization, Chinese terms
+  - **Research-Validated Mode** (`show_advanced_info=True`): M-RoPE, guidance scale 6-8, dual-pathway architecture
+- System prompt automatically adapts to user's configuration
+
+**Impact:** Node now matches output pattern of all other camera nodes (Object Focus Camera v7/v6/v5, Scene Photographer) with `(prompt, system_prompt, description)` structure.
+
+---
+
+### ✅ 2. Prompt Format Fixes
+**File:** [nodes/camera/cinematography_prompt_builder.py](nodes/camera/cinematography_prompt_builder.py)
+**Documentation:** [PROMPT_FORMAT_FIXES.md](PROMPT_FORMAT_FIXES.md)
+
+**3 Critical Bugs Fixed:**
+
+#### Bug 1: Using Abbreviations Instead of Full Shot Names
+**Before:** `A shoulder level ecu of stove oven...`
+**After:** `An eye-level extreme close-up of stove oven...`
+**Fix:** Added `get_shot_full_name()` method returning spelled-out shot types
+
+#### Bug 2: Vague Distance Descriptions
+**Before:** `...taken from very close distance...`
+**After:** `...taken from a vantage point thirty centimeters away...`
+**Fix:** Always use specific distance in natural language (centimeters for <1m, meters for ≥1m)
+
+#### Bug 3: Incorrect Angle Names
+**Before:** `A shoulder level...` (doesn't exist in cinematography)
+**After:** `An eye-level...`
+**Fix:** Proper angle cleaning preserves standard cinematography terms
+
+**Result:** Prompts now match working example format exactly with natural language, spelled-out shot types, and specific distances.
+
+---
+
+### ✅ 3. Comprehensive Camera Prompting Guide

+**Documentation:** [CUSTOM_DETAILS_TOOLTIP_ENHANCEMENT.md](CUSTOM_DETAILS_TOOLTIP_ENHANCEMENT.md)
+
+**Enhancement:**
+Updated `custom_details` parameter tooltip with **6 working examples** covering essential categories:
+
+1. **Compositional Framing**: "The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above"
+2. **Detail Isolation**: "focusing on the intricate details of a single burner and the cast-iron grate"
+3. **Component Naming**: "showing dial and hands clearly"
+4. **Vantage Point Reinforcement**: "The vantage point is inches away, creating an extremely shallow depth of field"
+5. **Bokeh Description**: "dissolves into a soft, blurred bokeh"
+6. **Lighting Specifics**: "The lighting is bright and even, keeping the entire area in sharp focus"
+
+**Impact:** Users now have clear guidance on what compositional specifics to add beyond the 5 core ingredients, with all examples taken from validated working prompts.

+
+## Key Technical Implementation Details
+
+### System Prompt Logic (Lines 390-441)
+
+```python
+def _get_cinematography_system_prompt(self, prompt_language, show_advanced_info,
+                                      material_preset, quality_preset):
+    """Generate dynamic system prompt based on configuration."""
+
+    # PROFESSIONAL MODE: Chinese + dx8152 LoRA optimization + presets
+    if (prompt_language in ["Chinese (Best for dx8152 LoRAs)", "Hybrid (Chinese + English)"]
+        and (material_preset != "None (Manual entry)" or quality_preset != "None (Manual entry)")):
+        return "You are a professional cinematographer specializing in Qwen-VL camera control..."
+
+    # RESEARCH-VALIDATED MODE: Advanced technical mode with PDF findings
+    elif show_advanced_info:
+        return "You are an expert cinematographer trained in vision-language spatial reasoning..."
+
+    # SIMPLE/BEGINNER MODE: Nanobanan's 5-ingredient framework (default)
+    else:
+        return "You are a professional photographer following the five-ingredient framework..."
+```
+
+### Full Shot Name Logic (Lines 369-381)
+
+```python
+def get_shot_full_name(self, shot_type):
+    """Extract full natural language name from shot type (not abbreviation)"""
+    full_names = {
+        "Extreme Close-Up (ECU)": "extreme close-up",
+        "Close-Up (CU)": "close-up",
+        "Medium Close-Up (MCU)": "medium close-up",
+        "Medium Shot (MS)": "medium shot",
+        "Medium Long Shot (MLS)": "medium long shot",
+        "Full Shot (FS)": "full shot",
+        "Wide Shot (WS)": "wide shot",
+        "Extreme Wide Shot (EWS)": "extreme wide shot"
+    }
+    return full_names.get(shot_type, shot_type.lower().split("(")[0].strip())
+```
+
+### Distance Formatting Logic (Lines 474-479)
+
+```python
+# Distance: "taken from a vantage point [distance] meters away" (ALWAYS specific)
+# For distances under 1 meter, use "centimeters" for better readability
+if distance < 1.0:
+    cm_distance = int(distance * 100)
+    cm_words = self._int_to_words(cm_distance)
+    parts.append(f"taken from a vantage point {cm_words} centimeters away")
+else:
+    parts.append(f"taken from a vantage point {distance_words} meters away")
+```
+
+---
+
+## Research Integration
+
+All implementations incorporate findings from **"Camera View Control in Vision-Language Image Editing Models"** research paper:
+
+1. **Five-Ingredient Framework** (Page 5): Subject, shot type, angle, focus/DOF, style
+2. **Distance-Based Positioning** (Page 5): "10m to the left" > "45 degrees counterclockwise"
+3. **M-RoPE Position Embeddings** (Page 1-2): 3D spatial understanding
+4. **Dual-Encoding Pathways** (Page 2-3): Semantic (identity) + Reconstructive (appearance)
+5. **Guidance Scale 6-8** (Page 4): Optimal for camera control workflows
+6. **Natural Language Paradigm** (Page 5): No pixel coordinates, spatial language
+
+---
+

+### ✅ Python Syntax Validation
+```bash
+python -m py_compile cinematography_prompt_builder.py
+```
+**Result:** SUCCESS - No syntax errors
+
+### ✅ Integration Validation

+
+### ✅ Output Validation
+**Before Fix (Broken):**
+```
+A shoulder level ecu of stove oven, taken from very close distance, with very shallow depth of field creating blurred background, in architectural style
+```
+
+**After Fix (Working):**
+```
+An eye-level extreme close-up of stove oven, taken from a vantage point thirty centimeters away, with very shallow depth of field creating blurred background, in architectural style
+```
+
+**Comparison with Working Example Format:**
+```
+An eye-level full shot of the green stove, taken from a vantage point 4 meters away. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
+```

+
+## Key Features Demonstrated
+
+### 1. Auto-Calculations
+- **Shot Size → Distance**: Full Shot = 4.5m, Close-Up = 0.8m, etc.
+- **Shot Size → Lens**: Close-Up = Portrait 85mm, Wide Shot = Wide Angle 24-35mm
+- **Shot Size → DOF**: Wide Shot = Deep, Close-Up = Shallow
+
+### 2. Number-to-Words Conversion
+- `4.5` → "four and a half"
+- `2.5` → "two and a half"
+- `0.3` → "point three"
+- **Critical**: Prevents numbers appearing as text in generated images
+
+### 3. Dual Prompt Formats
+- **Simple Prompt**: Nanobanan-style natural language (English only)
+- **Professional Prompt**: v7-style with Chinese cinematography terms + "Next Scene:" prefix
+- **Description**: Human-readable summary with emojis
+
+### 4. Parameter Validation
+- Wide Shot + Shallow DOF → ⚠️ Warning
+- Macro Lens + Wide Shot → ⚠️ Warning
+- Telephoto + Wide FOV → ⚠️ Warning
+
+### 5. Multi-Language Support
+- **English Only**: Simple natural descriptions
+- **Chinese (Best)**: Full Chinese cinematography terms
+- **Hybrid**: Chinese camera terms + English details (best for dx8152 LoRAs)
+
+---
+
+## Node Outputs
+
+The node provides 3 outputs:
+
+1. **simple_prompt** (STRING): Nanobanan-style descriptive format
+   - "An eye-level close-up of the watch, taken from..."

+# Custom Details Tooltip Enhancement
+
+## Summary
+
+Enhanced the `custom_details` parameter tooltip in Cinematography Prompt Builder to provide clear examples of compositional specifics that go beyond the 5 core ingredients (Subject, Shot Type, Angle, Focus/DOF, Style).
+
+---
+
+## Changes Made
+
+### File: nodes/camera/cinematography_prompt_builder.py
+
+**Lines 274-284**: Updated `custom_details` tooltip
+
+**Before:**
+```python
+"custom_details": ("STRING", {
+    "default": "",
+    "multiline": True,
+    "tooltip": "Add any custom details (e.g., 'showing dial and hands', 'with marble backsplash visible')"
+}),
+```
+
+**After:**
+```python
+"custom_details": ("STRING", {
+    "default": "",
+    "multiline": True,
+    "tooltip": "Add compositional specifics beyond the 5 ingredients. Examples:\n"
+               "• 'The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above'\n"
+               "• 'focusing on the intricate details of a single burner and the cast-iron grate'\n"
+               "• 'showing dial and hands clearly'\n"
+               "• 'The vantage point is inches away, creating an extremely shallow depth of field'\n"
+               "• 'dissolves into a soft, blurred bokeh'\n"
+               "• 'The lighting is bright and even, keeping the entire area in sharp focus'"
+}),
+```
+
+---
+
+## Why This Matters
+
+### Problem
+The 5-ingredient formula (Subject, Shot Type, Angle, Focus/DOF, Style) provides the **foundation** for camera prompts, but working examples show that **rich compositional details** make the difference between good and great results.
+
+**Example:**
+
+**5 Ingredients Only:**
+```
+An eye-level full shot of the green stove, taken from a vantage point four and a half meters away, with deep depth of field, in clean and modern style
+```
+
+**5 Ingredients + Custom Details:**
+```
+An eye-level full shot of the green stove, taken from a vantage point four and a half meters away, with deep depth of field, in clean and modern style. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
+```
+
+The second prompt provides:
+- **Composition guidance** ("entire stove is centered")
+- **Context inclusion** ("marble backsplash, range hood above")
+- **Lighting specifics** ("bright and even")
+- **Focus distribution** ("entire cooking area in sharp focus")
+
+---
+
+## Examples from Working Prompts
+
+All examples are taken directly from the working prompts documented in [CAMERA_PROMPTING_GUIDE.md](CAMERA_PROMPTING_GUIDE.md):
+
+### Example 1: Full Shot - Compositional Framing
+**Custom Detail:**
+```
+The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above
+```
+
+**Why It Works:**
+- Specifies exact subject placement ("centered in the frame")
+- Lists contextual elements to include ("marble backsplash", "range hood")
+- Ensures comprehensive view ("entire stove")
+
+---
+
+### Example 2: Extreme Macro - Focus Control
+**Custom Detail:**
+```
+focusing on the intricate details of a single burner and the cast-iron grate
+```
+
+**Why It Works:**
+- Specifies what to isolate ("single burner")
+- Emphasizes detail level ("intricate details")
+- Names specific components ("cast-iron grate")
+
+---
+
+### Example 3: Extreme Macro - Bokeh Description
+**Custom Detail:**
+```
+The vantage point is inches away, creating an extremely shallow depth of field where only the front edge of the burner is in sharp focus, and the rest of the stove and kitchen dissolves into a soft, blurred bokeh
+```
+
+**Why It Works:**
+- Reinforces proximity ("inches away")
+- Describes focus falloff precisely ("only the front edge")
+- Uses evocative language for blur ("dissolves into soft, blurred bokeh")
+
+---
+
+### Example 4: Full Shot - Lighting Details
+**Custom Detail:**
+```
+The lighting is bright and even, keeping the entire area in sharp focus
+```
+
+**Why It Works:**
+- Specifies lighting quality ("bright and even")
+- Connects lighting to focus ("keeping entire area in sharp focus")
+
+---
+
+### Example 5: Watch Detail - Component Naming
+**Custom Detail:**
+```
+showing dial and hands clearly
+```
+
+**Why It Works:**
+- Names specific components to emphasize
+- Ensures clarity ("clearly")
+
+---
+
+## How Users Should Use Custom Details
+
+### 1. Start with the 5 Ingredients (Foundation)
+Set these parameters in the node:
+- **Subject:** "the green stove"
+- **Shot Type:** "Full Shot (FS)"
+- **Angle:** "Eye Level"
+- **Depth of Field:** "Deep"
+- **Style:** "Clean/Modern"
+
+### 2. Add Custom Details (Enhancement)
+In the `custom_details` field, add compositional specifics:
+```
+The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
+```
+
+### 3. Result
+The node generates a complete prompt combining both:
+```
+An eye-level full shot of the green stove, taken from a vantage point four and a half meters away, with deep depth of field keeping everything in focus, in clean and modern style. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
+```
+
+---
+
+## Categories of Custom Details
+
+The tooltip examples cover 6 essential categories:
+
+### 1. Compositional Framing
+```
+"The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above"
+```
+**Use for:** Subject placement, contextual elements, framing guidance
+
+---
+
+### 2. Detail Isolation
+```
+"focusing on the intricate details of a single burner and the cast-iron grate"
+```
+**Use for:** Macro shots, close-ups, component emphasis
+
+---
+
+### 3. Component Naming
+```
+"showing dial and hands clearly"
+```
+**Use for:** Specific parts to emphasize, clarity requirements
+
+---
+
+### 4. Vantage Point Reinforcement
+```
+"The vantage point is inches away, creating an extremely shallow depth of field"
+```
+**Use for:** Extreme close-ups, macro, proximity emphasis
+
+---
+
+### 5. Bokeh Description
+```
+"dissolves into a soft, blurred bokeh"
+```
+**Use for:** Shallow DOF shots, background treatment, artistic blur
+
+---
+
+### 6. Lighting Specifics
+```
+"The lighting is bright and even, keeping the entire area in sharp focus"
+```
+**Use for:** Lighting quality, brightness, mood, focus relationship
+
+---

+# Horizontal Angle + Perspective Correction Implementation
+
+## Summary
+
+Added two powerful new features to the Cinematography Prompt Builder to enable precise architectural photography control:
+
+1. **Horizontal Angle** - Control camera position around the object (0°, 15°, 30°, 45°, 90°, 180°)
+2. **Perspective Correction** - Keep vertical lines straight for professional architectural photography
+
+**Implementation Date:** 2025-01-07
+**Version:** v2.4.0 (pending release)
+
+---
+
+## What Was Added
+
+### 1. Horizontal Angle Parameter
+
+**Location:** [cinematography_prompt_builder.py:138-157](nodes/camera/cinematography_prompt_builder.py#L138-L157)
+
+```python
+"horizontal_angle": ([
+    "Front View (0°)",
+    "Angled Left 15°",
+    "Angled Left 30°",
+    "Angled Left 45°",
+    "Side Left (90°)",
+    "Back View (180°)",
+    "Side Right (90°)",
+    "Angled Right 45°",
+    "Angled Right 30°",
+    "Angled Right 15°"
+], {
+    "default": "Front View (0°)",
+    "tooltip": "Horizontal camera position around the object:\n"
+               "• Front (0°) = Straight-on view\n"
+               "• Angled (15-45°) = Corner/three-quarter view\n"
+               "• Side (90°) = Profile view\n"
+               "• Back (180°) = Rear view"
+})
+```
+
+**Purpose:** Allows users to control the camera's orbital position around the subject, from straight-on frontal views to side profiles and rear views.
+
+---
+
+### 2. Perspective Correction Parameter
+
+**Location:** [cinematography_prompt_builder.py:223-233](nodes/camera/cinematography_prompt_builder.py#L223-L233)
+
+```python
+"perspective_correction": ([
+    "Natural (Standard Lens)",
+    "Architectural (Keep Verticals Straight)",
+    "Tilt-Shift (Full Perspective Control)"
+], {
+    "default": "Natural (Standard Lens)",
+    "tooltip": "Control vertical line convergence for architectural photography:\n"
+               "• Natural = Standard perspective with natural converging lines\n"
+               "• Architectural = Keep vertical lines parallel (requires eye-level framing)\n"
+               "• Tilt-Shift = Professional perspective correction with selective focus plane"
+})
+```
+
+**Purpose:** Enables professional architectural photography with straight vertical lines, preventing converging lines and keystoning distortion.
+
+---
+
+## Helper Methods Added
+
+### 1. `_get_horizontal_angle_description()`
+
+**Location:** [cinematography_prompt_builder.py:422-460](nodes/camera/cinematography_prompt_builder.py#L422-L460)
+
+Converts horizontal angle selections into natural language descriptions in both English and Chinese:
+
+**Examples:**
+- "Front View (0°)" → `("", "")` (no explicit mention needed)
+- "Angled Left 30°" → `("from thirty degrees to the left for a corner perspective", "从左侧30度拍摄,呈现转角视角")`
+- "Side Left (90°)" → `("from the left side for a profile view", "从左侧拍摄,呈现侧面视角")`
+
+---
+
+### 2. `_get_perspective_correction_prompting()`
+
+**Location:** [cinematography_prompt_builder.py:462-481](nodes/camera/cinematography_prompt_builder.py#L462-L481)
+
+Generates perspective correction guidance text:
+
+**Examples:**
+
+**Architectural Mode:**
+```
+English: "with careful framing to keep all vertical lines parallel and prevent perspective distortion,
+          maintaining straight architectural lines throughout the frame"
+Chinese: "保持所有垂直线平行,防止透视畸变,确保建筑线条笔直"
+```
+
+**Tilt-Shift Mode:**
+```
+English: "using a tilt-shift lens for perspective correction to keep all vertical lines perfectly parallel,
+          with precise control over the focus plane and no keystoning distortion"
+Chinese: "使用移轴镜头进行透视校正,保持所有垂直线完美平行,精确控制焦平面,无梯形失真"
+```
+
+---
+
+## Updated Methods
+
+### 1. `validate_parameters()` - Enhanced Validation
+
+**Location:** [cinematography_prompt_builder.py:483-514](nodes/camera/cinematography_prompt_builder.py#L483-L514)
+
+**Added validation rule:**
+```python
+# Perspective correction + non-level camera angle conflict
+if perspective_correction in ["Architectural (Keep Verticals Straight)",
+                               "Tilt-Shift (Full Perspective Control)"]:
+    if camera_angle in ["High Angle (looking down)", "Low Angle (looking up)",
+                       "Bird's Eye View (overhead)", "Worm's Eye View (ground up)"]:
+        warnings.append(
+            "⚠️ Perspective correction requires eye-level camera angle. "
+            "Vertical lines will converge with tilted camera positions. "
+            "Use 'Eye Level' or 'Shoulder Level' for straight verticals."
+        )
+```
+
+**Why this matters:** You cannot maintain straight vertical lines if the camera is tilted up or down. This validation warns users about incompatible parameter combinations.
+
+---
+
+### 2. `generate_cinematography_prompt()` - Function Signature Update
+
+**Location:** [cinematography_prompt_builder.py:583-593](nodes/camera/cinematography_prompt_builder.py#L583-L593)
+
+**Added parameters:**
+```python
+def generate_cinematography_prompt(self, target_subject, shot_type, camera_angle,
+                                  depth_of_field, style_mood, prompt_language,
+                                  horizontal_angle="Front View (0°)",  # NEW
+                                  lens_type_override="Auto (from shot size)",
+                                  perspective_correction="Natural (Standard Lens)",  # NEW
+                                  camera_movement="Static (No Movement)",
+                                  ...
+```
+
+**Auto-Selection Logic** (Lines 585-591):
+```python
+# Determine lens (with tilt-shift auto-selection for perspective correction)
+if perspective_correction == "Tilt-Shift (Full Perspective Control)":
+    lens_type = "Tilt-Shift (Perspective Control)"  # Auto-select tilt-shift lens
+elif lens_type_override == "Auto (from shot size)":
+    lens_type = shot_defaults["lens"]
+else:
+    lens_type = lens_type_override
+```
+
+**When "Tilt-Shift (Full Perspective Control)" is selected, the node automatically uses a tilt-shift lens regardless of lens_type_override setting.**
+
+---
+
+### 3. `_generate_simple_prompt()` - Enhanced Prompt Generation
+
+**Location:** [cinematography_prompt_builder.py:629-679](nodes/camera/cinematography_prompt_builder.py#L629-L679)
+
+**Added sections:**
+```python
+# Horizontal angle (if not front view)
+if horizontal_desc_en:
+    parts.append(f"positioned {horizontal_desc_en}")
+
+# Perspective correction (if enabled)
+if perspective_desc_en:
+    parts.append(perspective_desc_en)
+```
+
+**Example Output Comparison:**
+
+**Before (without new features):**
+```
+An eye-level full shot of modern kitchen, taken from a vantage point four and a half meters away,
+with deep depth of field keeping everything in focus, in architectural style
+```
+
+**After (with horizontal angle + perspective correction):**
+```
+An eye-level full shot of modern kitchen, taken from a vantage point four and a half meters away,
+positioned from thirty degrees to the left for a corner perspective, with careful framing to keep
+all vertical lines parallel and prevent perspective distortion, maintaining straight architectural
+lines throughout the frame, with deep depth of field keeping everything in focus, in architectural style
+```
+
+---
+
+### 4. `_generate_professional_prompt()` - Chinese Translation Support
+
+**Location:** [cinematography_prompt_builder.py:711-806](nodes/camera/cinematography_prompt_builder.py#L711-L806)
+
+**Added horizontal angle + perspective to Chinese section:**
+```python
+# Horizontal angle (if not front view)
+if horizontal_desc_zh:
+    chinese_parts.append(horizontal_desc_zh)
+
+# Perspective correction (if enabled)
+if perspective_desc_zh:
+    chinese_parts.append(perspective_desc_zh)
+```
+
+**Added to English section:**
+```python
+base = f"Next Scene: Change to {lens}, {shot_abbreviation} framing, {angle} viewing {subject}"
+if horizontal_desc_en:
+    base += f", positioned {horizontal_desc_en}"
+if perspective_desc_en:
+    base += f", {perspective_desc_en}"
+```
+

+### 5. `_get_cinematography_system_prompt()` - Architectural Guidance
+
+**Location:** [cinematography_prompt_builder.py:516-581](nodes/camera/cinematography_prompt_builder.py#L516-L581)
+
+**Added architectural perspective guidance:**
+```python
+# Architectural perspective guidance (appended to all modes if enabled)
+architectural_guidance = ""
+if perspective_correction in ["Architectural (Keep Verticals Straight)", "Tilt-Shift (Full Perspective Control)"]:
+    architectural_guidance = (
+        " IMPORTANT: Maintain parallel vertical lines in architectural photography. "
+        "Keep the camera level (no upward or downward tilt) to prevent converging verticals and keystoning. "
+        "All vertical architectural elements (walls, doors, columns, windows) must remain straight and parallel in the frame. "
+        "This requires eye-level camera positioning without vertical angle deviation."
+    )
+```
+
+This guidance is **automatically appended** to all three system prompt modes (Professional, Research-Validated, Simple/Beginner) when perspective correction is enabled.
+
+---
+
+## Usage Examples
+
+### Example 1: Straight Architectural View with Perspective Correction
+
+**Parameters:**
+- Subject: `modern kitchen`
+- Shot Type: `Full Shot (FS)`
+- Camera Angle: `Eye Level`
+- **Horizontal Angle: `Front View (0°)`** ⭐
+- **Perspective Correction: `Architectural (Keep Verticals Straight)`** ⭐
+- DOF: `Deep`
+- Style: `Architectural`
+
+**Generated Simple Prompt:**
+```
+An eye-level full shot of modern kitchen, taken from a vantage point four and a half meters away,
+with careful framing to keep all vertical lines parallel and prevent perspective distortion,
+maintaining straight architectural lines throughout the frame, with deep depth of field keeping
+everything in focus, in architectural style
+```
+
+**System Prompt Addition:**
+```
+IMPORTANT: Maintain parallel vertical lines in architectural photography. Keep the camera level
+(no upward or downward tilt) to prevent converging verticals and keystoning. All vertical
+architectural elements (walls, doors, columns, windows) must remain straight and parallel in the frame.
+This requires eye-level camera positioning without vertical angle deviation.
+```
+
+---
+
+### Example 2: Corner View with Perspective Correction
+
+**Parameters:**
+- Subject: `living room`
+- Shot Type: `Wide Shot (WS)`
+- Camera Angle: `Eye Level`
+- **Horizontal Angle: `Angled Left 30°`** ⭐
+- **Perspective Correction: `Architectural (Keep Verticals Straight)`** ⭐
+- DOF: `Deep`
+- Style: `Clean/Modern`
+
+**Generated Simple Prompt:**
+```
+An eye-level wide shot of living room, taken from a vantage point six and a half meters away,
+positioned from thirty degrees to the left for a corner perspective, with careful framing to keep
+all vertical lines parallel and prevent perspective distortion, maintaining straight architectural
+lines throughout the frame, with deep depth of field keeping everything in focus, in clean and modern style
+```
+
+**Key Features:**
+- ✅ Horizontal angle specified ("thirty degrees to the left")
+- ✅ Perspective correction guidance included
+- ✅ Natural language throughout
+- ✅ Comprehensive architectural framing
+
+---
+
+### Example 3: Professional Tilt-Shift with Side Angle
+
+**Parameters:**
+- Subject: `architectural exterior facade`
+- Shot Type: `Full Shot (FS)`
+- Camera Angle: `Eye Level`
+- **Horizontal Angle: `Side Left (90°)`** ⭐
+- **Perspective Correction: `Tilt-Shift (Full Perspective Control)`** ⭐
+- DOF: `Deep`
+- Style: `Architectural`
+- **Lens:** Auto-selected to `Tilt-Shift (Perspective Control)`
+
+**Generated Simple Prompt:**
+```
+An eye-level full shot of architectural exterior facade, taken from a vantage point four and a half meters away,
+positioned from the left side for a profile view, using a tilt-shift lens for perspective correction to keep
+all vertical lines perfectly parallel, with precise control over the focus plane and no keystoning distortion,
+with deep depth of field, in architectural style
+```
+
+**Key Features:**
+- ✅ Automatic tilt-shift lens selection
+- ✅ Side profile positioning
+- ✅ Professional perspective correction language
+- ✅ Focus plane control mentioned
+
+---
+
+### Example 4: Invalid Combination - Validation Warning
+
+**Parameters:**
+- Subject: `building`
+- Shot Type: `Full Shot (FS)`
+- **Camera Angle: `Low Angle (looking up)`** ⚠️
+- Horizontal Angle: `Front View (0°)`
+- **Perspective Correction: `Architectural (Keep Verticals Straight)`** ⚠️
+
+**Validation Warning:**
+```
+⚠️ Perspective correction requires eye-level camera angle. Vertical lines will converge with
+tilted camera positions. Use 'Eye Level' or 'Shoulder Level' for straight verticals.
+```
+
+**Why:** You cannot keep vertical lines parallel when the camera is tilted upward (low angle). The validation system warns users about this incompatibility.
+
+---
+
+## Perspective Correction Modes Explained
+
+### Mode 1: Natural (Standard Lens) - Default
+
+**When to use:** General photography where natural perspective convergence is acceptable.
+
+**Characteristics:**
+- Vertical lines converge naturally (especially with wide-angle lenses)
+- Standard perspective rendering
+- No special corrections applied
+
+**Generated Prompt:**
+```
+An eye-level full shot of kitchen, taken from a vantage point four and a half meters away
+```
+(No perspective guidance added)
+
+---
+
+### Mode 2: Architectural (Keep Verticals Straight) - Recommended for Interior Design
+
+**When to use:** Professional architectural photography, interior design visualization, real estate photography.
+
+**Characteristics:**
+- Emphasizes parallel vertical lines
+- Prevents keystoning
+- Requires eye-level camera positioning
+- Standard architectural photography technique
+
+**Generated Prompt:**
+```
+An eye-level full shot of kitchen, taken from a vantage point four and a half meters away,
+with careful framing to keep all vertical lines parallel and prevent perspective distortion,
+maintaining straight architectural lines throughout the frame
+```
+
+**System Prompt Guidance:**
+```
+IMPORTANT: Maintain parallel vertical lines in architectural photography. Keep the camera level
+(no upward or downward tilt) to prevent converging verticals and keystoning.
+```
+
+---
+
+### Mode 3: Tilt-Shift (Full Perspective Control) - Professional
+
+**When to use:** Professional architectural photography requiring both perspective correction AND selective focus control.
+
+**Characteristics:**
+- Uses tilt-shift lens (auto-selected)
+- Full perspective correction
+- Selective focus plane control
+- Zero keystoning distortion
+- Most professional option
+
+**Generated Prompt:**
+```
+An eye-level full shot of kitchen, taken from a vantage point four and a half meters away,
+using a tilt-shift lens for perspective correction to keep all vertical lines perfectly parallel,
+with precise control over the focus plane and no keystoning distortion
+```
+
+**Auto-Selection:** Lens automatically changes to "Tilt-Shift (Perspective Control)" regardless of lens_type_override setting.

+## Horizontal Angle Options Explained
+
+| Angle | Description | Use Case | Natural Language Output |
+|-------|-------------|----------|------------------------|
+| **Front View (0°)** | Straight-on, face-to-face | Product photography, symmetrical compositions | (no explicit mention) |
+| **Angled Left/Right 15°** | Slight offset | Subtle three-dimensionality | "from fifteen degrees to the left/right" |
+| **Angled Left/Right 30°** | Corner perspective | Interior corners, three-quarter views | "from thirty degrees to the left/right for a corner perspective" |
+| **Angled Left/Right 45°** | Strong three-quarter | Classic three-quarter product view | "from forty-five degrees to the left/right for a three-quarter view" |
+| **Side Left/Right (90°)** | Profile view | Architectural elevations, profiles | "from the left/right side for a profile view" |
+| **Back View (180°)** | Rear view | Back details, reverse angles | "from behind the subject" |

+## Technical Implementation Details
+
+### Parameter Order in Function Signature
+
+```python
+def generate_cinematography_prompt(
+    self,
+    # Core 5 ingredients (required)
+    target_subject,
+    shot_type,
+    camera_angle,
+    depth_of_field,
+    style_mood,
+    prompt_language,
+
+    # NEW: Horizontal positioning (optional)
+    horizontal_angle="Front View (0°)",
+
+    # Professional enhancements (optional)
+    lens_type_override="Auto (from shot size)",
+
+    # NEW: Perspective control (optional)
+    perspective_correction="Natural (Standard Lens)",
+
+    camera_movement="Static (No Movement)",
+    lighting_style="Auto/Natural",
+    material_detail_preset="None (Manual entry)",
+    photography_quality_preset="None (Manual entry)",
+    custom_details="",
+    show_advanced_info=False
+):
+```
+
+**Design Rationale:**
+1. Core 5 ingredients remain first (required parameters)
+2. `horizontal_angle` added after core parameters (new positioning control)
+3. `perspective_correction` added after lens override (architectural enhancement)
+4. All new parameters have sensible defaults (backwards compatible)
+
+---
+
+### Validation Logic Flow
+
+```python
+1. User selects parameters
+2. Node calls validate_parameters(shot_type, dof, lens_type, camera_angle, perspective_correction)
+3. Validation checks:
+   - Wide shot + Shallow DOF → Warning
+   - Macro lens + Wide shot → Warning
+   - Telephoto + Wide shot → Warning
+   - **Perspective correction + Non-level angle → Warning** ⭐ NEW
+4. Warnings displayed in description output
+```
+
+---
+
+### Prompt Generation Flow
+
+```python
+1. Get shot defaults (distance, lens, DOF)
+2. Auto-select tilt-shift lens if perspective_correction == "Tilt-Shift"
+3. Validate parameters
+4. Generate Simple Prompt:
+   - Opening (angle + shot + subject)
+   - Distance (meters/centimeters)
+   - **Horizontal angle (if not front view)** ⭐ NEW
+   - **Perspective correction (if enabled)** ⭐ NEW
+   - DOF description
+   - Style/Mood
+   - Lighting
+   - Custom details
+5. Generate Professional Prompt (Chinese + English with same additions)
+6. Generate System Prompt (with architectural guidance if enabled)
+7. Generate Description (with warnings)
+8. Return (simple_prompt, professional_prompt, system_prompt, description)
+```
+
+---
+
+## Compatibility
+
+### Backwards Compatibility
+
+✅ **Fully backwards compatible** - All new parameters have defaults:
+- `horizontal_angle="Front View (0°)"` (no explicit mention in prompt)
+- `perspective_correction="Natural (Standard Lens)"` (no special corrections)
+
+**Existing workflows** using the Cinematography Prompt Builder will continue working without modification.
+
+**New workflows** can leverage the new parameters for enhanced control.
+
+---
+
+### Language Support
+
+| Language Mode | Horizontal Angle | Perspective Correction |
+|---------------|------------------|------------------------|
+| English (Simple & Clear) | ✅ Full support | ✅ Full support |
+| Chinese (Best for dx8152 LoRAs) | ✅ Chinese translations | ✅ Chinese translations |
+| Hybrid (Chinese + English) | ✅ Both languages | ✅ Both languages |
+
+---
+
+## Benefits
+
+### 1. Precise Camera Positioning
+
+Users can now control:
+- **Vertical angle** (existing camera_angle parameter)
+- **Horizontal angle** (NEW horizontal_angle parameter)
+- **Distance** (shot size determines distance)
+
+This provides **full 3D camera positioning control** around the subject.
+
+---
+
+### 2. Professional Architectural Photography
+
+The perspective correction feature enables:
+- ✅ Straight vertical lines (no converging lines)
+- ✅ No keystoning distortion
+- ✅ Professional architectural presentation
+- ✅ Real estate photography standards
+- ✅ Interior design visualization quality
+
+---
+
+### 3. Research-Validated Approach
+
+**Horizontal angles use natural language:**
+- "from thirty degrees to the left" (NOT "rotate 30 degrees")
+- Aligns with research finding that **distance-based positioning is more reliable than degree-based**
+
+**Perspective correction is explicit:**
+- Clear guidance in prompts
+- System prompt reinforcement
+- Validation warnings for incompatible settings
+
+---
+
+### 4. User-Friendly Design
+
+- **Clear tooltips** explain each option
+- **Validation warnings** prevent mistakes
+- **Auto-selection** (tilt-shift lens when needed)
+- **Sensible defaults** (Front View, Natural perspective)
+- **Progressive enhancement** (start simple, add complexity as needed)
+
+---

+# Prompt Format Fixes - Natural Language Improvements
+
+## Summary
+
+Fixed 3 critical bugs in the Simple Prompt generation to match natural language style of working examples.
+
+---
+
+## 🐛 Bugs Fixed
+
+### **Bug 1: Using Abbreviations Instead of Full Shot Names**
+
+**Before (WRONG):**
+```
+A shoulder level ecu of stove oven...
+```
+
+**After (CORRECT):**
+```
+An eye-level extreme close-up of stove oven...
+```
+
+**Fix:** Added `get_shot_full_name()` method to return spelled-out shot types instead of abbreviations.
+
+---
+
+### **Bug 2: Vague Distance Descriptions**
+
+**Before (WRONG):**
+```
+...taken from very close distance...
+```
+
+**After (CORRECT):**
+```
+...taken from a vantage point thirty centimeters away...
+```
+
+**Fix:** Always use specific distance in natural language (centimeters for <1m, meters for ≥1m).
+
+---
+
+### **Bug 3: Incorrect Angle Names**
+
+**Before (WRONG):**
+```
+A shoulder level...
+```
+(Note: "shoulder level" doesn't exist in cinematography)
+
+**After (CORRECT):**
+```
+An eye-level...
+```
+
+**Fix:** Proper angle cleaning now preserves standard cinematography terms.
+
+---
+

+- ✅ "six and a half meters away" (standard WS distance)
+
+---
+
+## 🔧 Technical Changes
+
+### 1. Added `get_shot_full_name()` Method (Lines 369-381)
+
+```python
+def get_shot_full_name(self, shot_type):
+    """Extract full natural language name from shot type (not abbreviation)"""
+    full_names = {
+        "Extreme Close-Up (ECU)": "extreme close-up",
+        "Close-Up (CU)": "close-up",
+        "Medium Close-Up (MCU)": "medium close-up",
+        "Medium Shot (MS)": "medium shot",
+        "Medium Long Shot (MLS)": "medium long shot",
+        "Full Shot (FS)": "full shot",
+        "Wide Shot (WS)": "wide shot",
+        "Extreme Wide Shot (EWS)": "extreme wide shot"
+    }
+    return full_names.get(shot_type, shot_type.lower().split("(")[0].strip())
+```
+
+---
+
+### 2. Updated `_generate_simple_prompt()` (Lines 524-546)
+
+**Changed from:**
+```python
+# Get shot abbreviation
+shot_abbr = self.get_shot_abbreviation(shot_type).lower()  # Returns "ecu"
+```
+
+**To:**
+```python
+# Get FULL shot name (not abbreviation) for natural language
+shot_full = self.get_shot_full_name(shot_type)  # Returns "extreme close-up"
+```
+
+---
+
+### 3. Fixed Distance Formatting (Lines 539-546)
+
+**Changed from:**
+```python
+# Distance: "taken from [distance] away"
+if distance < 0.5:
+    parts.append("taken from very close distance")  # VAGUE
+elif distance < 1.0:
+    parts.append(f"taken from close distance")  # VAGUE
+else:
+    parts.append(f"taken from a vantage point {distance_words} meters away")
+```
+
+**To:**
+```python
+# Distance: "taken from a vantage point [distance] meters away" (ALWAYS specific)
+# For distances under 1 meter, use "centimeters" for better readability
+if distance < 1.0:
+    cm_distance = int(distance * 100)
+    cm_words = self._int_to_words(cm_distance)
+    parts.append(f"taken from a vantage point {cm_words} centimeters away")
+else:
+    parts.append(f"taken from a vantage point {distance_words} meters away")
+```
+
+**Result:**
+- 0.3m → "thirty centimeters away" (clear and natural)
+- 0.8m → "eighty centimeters away" (clear and natural)
+- 2.5m → "two and a half meters away" (clear and natural)
+- 4.5m → "four and a half meters away" (clear and natural)
+
+---
+
+## ✅ Verification
+
+### Distance Conversion Examples
+
+| Shot Type | Distance | Number | Natural Language Output |
+|-----------|----------|--------|------------------------|
+| ECU | 0.3m | 30cm | "thirty centimeters away" |
+| CU | 0.8m | 80cm | "eighty centimeters away" |
+| MCU | 1.2m | 1.2m | "one point two meters away" |
+| MS | 2.5m | 2.5m | "two and a half meters away" |
+| MLS | 3.5m | 3.5m | "three and a half meters away" |
+| FS | 4.5m | 4.5m | "four and a half meters away" |
+| WS | 6.5m | 6.5m | "six and a half meters away" |
+| EWS | 10.0m | 10.0m | "ten meters away" |
+
+---
+
+## 🎯 Result
+
+Your test output should now be:
+
+**BEFORE (Broken):**
+```
+A shoulder level ecu of stove oven, taken from very close distance, with very shallow depth of field creating blurred background, in architectural style
+```
+
+**AFTER (Fixed):**
+```
+An eye-level extreme close-up of stove oven, taken from a vantage point thirty centimeters away, with very shallow depth of field creating blurred background, in architectural style
+```
+
+**Comparison with Working Example Format:**
+```
+An eye-level full shot of the green stove, taken from a vantage point 4 meters away. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
+```
+
+**Match:** ✅ STRUCTURE MATCHES - Natural language, spelled-out shot types, specific distances
+

+**nodes/camera/cinematography_prompt_builder.py:**
+- Lines 369-381: Added `get_shot_full_name()` method
+- Line 525: Changed from `get_shot_abbreviation()` to `get_shot_full_name()`
+- Lines 539-546: Fixed distance formatting (specific centimeters/meters instead of vague descriptions)
+
+**Total changes:** ~25 lines modified/added
+
+---
+
+## 🧪 Testing

+## 1. Auto-Facing Feature Added to Cinematography Prompt Builder
+
+### What Changed
+Added `auto_facing` parameter to **Cinematography Prompt Builder** node, previously only available in Object Focus Camera v7.
+
+### Why Important
+User insight: "i know it is important if you merg it to prompt at begiing it will have more affect base on my experince"
+
+Based on vision-language model attention mechanisms, placing the facing directive at the **beginning** of prompts provides maximum attention weight and effectiveness.
+
+### Implementation Details
+
+**File**: `nodes/camera/cinematography_prompt_builder.py`
+
+1. **Added Parameter** (Lines 159-165):
+```python
+"auto_facing": ("BOOLEAN", {
+    "default": True,
+    "tooltip": "Automatically face camera toward target subject (recommended for object photography).\n"
+               "• True = Camera points directly at subject from chosen angle\n"
+               "• False = Camera positioned at angle but may not face subject directly"
+}),
+```
+
+2. **Simple Prompt Generation** (Lines 685-688):
+```python
+# AUTO-FACING: Add at the VERY BEGINNING for maximum attention weight
+# Only add if enabled AND not front view (front view already implies facing)
+if auto_facing and horizontal_angle != "Front View (0°)":
+    parts.append(f"Facing {subject} directly")
+```
+
+3. **Professional Prompt Generation** (Lines 757-763):
+```python
+# AUTO-FACING: Add at BEGINNING for maximum attention (before "Next Scene:")
+# Only add if enabled AND not front view
+if auto_facing and horizontal_angle != "Front View (0°)":
+    if language in ["Chinese (Best for dx8152 LoRAs)", "Hybrid (Chinese + English)"]:
+        prompt_parts.append(f"面对{subject}")  # "Facing {subject}"
+    else:
+        prompt_parts.append(f"Facing {subject} directly")
+```
+
+### Behavior
+- **Active**: When `auto_facing=True` AND `horizontal_angle != "Front View (0°)"`
+- **Inactive**: When `auto_facing=False` OR `horizontal_angle == "Front View (0°)"` (redundant)
+- **Language Support**: Full Chinese/English/Hybrid support
+
+---
+
+## 2. Parameter Order Bug Fix
+
+### Problem
+User reported: "i saw it is not working , the auto facing option is not working check it"
+
+### Root Cause
+Parameter order mismatch between INPUT_TYPES definition and function signature.
+
+ComfyUI passes parameters **positionally** based on INPUT_TYPES order. The function signature had parameters in wrong positions.
+
+**Before**:
+- INPUT_TYPES position 5: `auto_facing`
+- Function signature position 8: `auto_facing`
+
+### Fix
+Reordered function signature to match INPUT_TYPES exactly (Lines 591-601):
+```python
+def generate_cinematography_prompt(self, target_subject, shot_type, camera_angle,
+                                  horizontal_angle, auto_facing,  # CRITICAL: Must match INPUT_TYPES order
+                                  depth_of_field, style_mood, prompt_language,
+                                  ...)
+```
+
+**File**: `nodes/camera/cinematography_prompt_builder.py`
+
+---
+
+## 3. Chinese Distance Format Improvement
+
+### Problem
+User showed prompt: "距离远距离" (distance far distance) - redundant and unclear
+
+### Solution
+Changed `_get_distance_chinese()` function to return specific meter values instead of generic descriptions.
+
+**Before**: "远距离" (far distance)
+**After**: "四米" (4 meters)
+
+### Implementation (Lines 903-943)
+```python
+def _get_distance_chinese(self, distance):
+    """Convert distance to Chinese words with specific meter values"""
+    chinese_numbers = {
+        0: "零", 1: "一", 2: "两", 3: "三", 4: "四",
+        5: "五", 6: "六", 7: "七", 8: "八", 9: "九",
+        10: "十", 15: "十五", 20: "二十"
+    }
+
+    if distance == int(distance):
+        dist_int = int(distance)
+        if dist_int in chinese_numbers:
+            return f"{chinese_numbers[dist_int]}米"
+        else:
+            return f"{dist_int}米"
+    # ... handles half meters and decimals
+```
+
+**File**: `nodes/camera/cinematography_prompt_builder.py`
+
+---
+
+## 4. GRAG Nodes Fixed for ComfyUI Update
+
+### Problem
+User reported: "there is an update for comfyui and t broken my GRAG nodes"
+
+Error: `RuntimeError: The size of tensor a (8430) must match the size of tensor b (24)`
+
+### Root Cause
+ComfyUI commit `4cd881866bad0cde70273cc123d725693c1f2759` changed:
+- Tensor format: **BSHD → BHND** (Batch, Heads, Sequence, Dim)
+- RoPE function: `apply_rotary_emb` → `apply_rope1`
+- Import location: `comfy.ldm.qwen_image.model` → `comfy.ldm.flux.math`
+
+### Solution Applied
+
+**File**: `nodes/sampling/archai3d_grag_sampler.py`
+
+#### 1. QKV Projection Format (Lines 187-195)
+**Before**:
+```python
+img_query = attn_module.to_q(hidden_states).unflatten(-1, (attn_module.heads, -1))
+```
+
+**After**:
+```python
+img_query = attn_module.to_q(hidden_states).view(batch_size, seq_img, attn_module.heads, -1).transpose(1, 2).contiguous()
+```
+
+Changes to BHND format: `[B, H, N, D]`
+
+#### 2. Concatenation Dimension (Lines 203-206)
+**Before**: `dim=1` (sequence in BSHD)
+**After**: `dim=2` (sequence in BHND)
+
+```python
+joint_query = torch.cat([txt_query, img_query], dim=2)
+```
+
+#### 3. RoPE Function Update (Lines 208-211)
+**Before**:
+```python
+from comfy.ldm.qwen_image.model import apply_rotary_emb
+joint_query = apply_rotary_emb(joint_query, image_rotary_emb)
+```
+
+**After**:
+```python
+from comfy.ldm.flux.math import apply_rope1
+joint_query = apply_rope1(joint_query, image_rotary_emb)
+```
+
+#### 4. GRAG Processing Format Conversion (Lines 216-232)
+```python
+# Convert BHND to BSHD format for GRAG, then flatten
+# BHND: [B, H, S, D] -> BSHD: [B, S, H, D] -> [B, S, H*D]
+joint_key_for_grag = joint_key.transpose(1, 2).contiguous()  # BHND -> BSHD
+joint_key_flat = joint_key_for_grag.flatten(start_dim=2)  # [B, S, H*D]
+
+# Apply GRAG reweighting
+joint_key_flat = apply_grag_to_keys(...)
+
+# Unflatten back to BSHD then transpose back to BHND
+joint_key_for_grag = joint_key_flat.unflatten(-1, (attn_module.heads, -1))  # [B, S, H, D]
+joint_key = joint_key_for_grag.transpose(1, 2).contiguous()  # BSHD -> BHND
+```
+
+#### 5. Attention Call with skip_reshape (Lines 241-252)
+**Key Insight**: With `skip_reshape=True` and default `skip_output_reshape=False`:
+- **Input**: BHND format
+- **Output**: BSD format (not BHND!)
+
+```python
+# Pass tensors in BHND format with skip_reshape=True (new Qwen format)
+# Output will be BSD format (batch, seq, heads*dim) due to default skip_output_reshape=False
+joint_hidden_states = optimized_attention_masked(
+    joint_query, joint_key, joint_value, attn_module.heads,
+    attention_mask, transformer_options=transformer_options,
+    skip_reshape=True  # Input is BHND, output is BSD (due to default reshape)
+)
+
+# Split streams - output is already in BSD format, no transpose needed
+txt_attn_output = joint_hidden_states[:, :seq_txt, :]
+img_attn_output = joint_hidden_states[:, seq_txt:, :]
+```
+
+**Critical Fix**: Removed incorrect transpose that was treating output as BHND when it's actually BSD.
+
+### Testing
+User confirmed: "ok GRAG is working"
+
+---

+# System Prompt Addition - Cinematography Prompt Builder
+
+## Summary
+
+Added dynamic system prompt functionality to the Cinematography Prompt Builder node to match the pattern used by all other camera nodes (Object Focus Camera v7/v6/v5, Scene Photographer).
+
+---
+
+## Changes Made
+
+### 1. Updated RETURN_TYPES (Line 287-288)
+
+**Before:**
+```python
+RETURN_TYPES = ("STRING", "STRING", "STRING")
+RETURN_NAMES = ("simple_prompt", "professional_prompt", "description")
+```
+
+**After:**
+```python
+RETURN_TYPES = ("STRING", "STRING", "STRING", "STRING")
+RETURN_NAMES = ("simple_prompt", "professional_prompt", "system_prompt", "description")
+```
+
+**Impact:** Node now outputs 4 values instead of 3, adding system_prompt as the 3rd output
+
+---
+
+### 2. Added Dynamic System Prompt Method (Lines 390-441)
+
+Created `_get_cinematography_system_prompt()` method with **3 intelligent variants**:
+
+#### **Variant 1: Professional Mode** (Chinese + Presets)
+**Triggers when:**
+- Language is "Chinese (Best for dx8152 LoRAs)" OR "Hybrid (Chinese + English)"
+- AND material_preset OR quality_preset is selected
+
+**System Prompt:**
+```
+"You are a professional cinematographer specializing in Qwen-VL camera control.
+Execute precise camera positioning using industry-standard shot sizes (ECU to EWS),
+camera angles (eye level to bird's eye), and lens characteristics (14mm to 200mm+).
+Maintain subject identity across viewpoint changes while allowing visual appearance
+to transform appropriately. Use distance-based positioning (e.g., '2.5 meters')
+rather than degree-based angular specifications for consistent results.
+Process Chinese cinematography terms (构图, 查看) with high accuracy for dx8152 LoRA compatibility."
+```
+
+#### **Variant 2: Research-Validated Mode** (Advanced Technical)
+**Triggers when:**
+- `show_advanced_info = True`
+
+**System Prompt:**
+```
+"You are an expert cinematographer trained in vision-language spatial reasoning.
+Follow the five-ingredient prompting framework: subject description, shot type and framing,
+angle and vantage point, focus and depth of field, style or mood.
+Process camera instructions through natural language spatial relationships—no pixel coordinates.
+Maintain geometric consistency by preserving subject identity (semantic pathway) while
+adapting visual appearance (reconstructive pathway) across viewpoint changes.
+Use M-RoPE position embeddings for 3D spatial understanding.
+Optimal guidance scale: 6-8 for camera control workflows.
+Distance-based positioning ('2.5 meters away') produces more reliable results than
+degree-based angular specifications ('45 degrees counterclockwise')."
+```
+
+**Key Research Elements:**
+- M-RoPE position embeddings (from PDF page 1-2)
+- Dual-pathway architecture (semantic + reconstructive) (from PDF page 2-3)
+- Guidance scale 6-8 recommendation (from PDF page 4)
+- Distance-based vs degree-based positioning (from PDF page 5)
+
+#### **Variant 3: Simple/Beginner Mode** (Default - Nanobanan)
+**Triggers when:**
+- Default mode (no special conditions)
+
+**System Prompt:**
+```
+"You are a professional photographer following the five-ingredient framework:
+subject, shot type, angle, focus/depth of field, and style.
+Execute camera positioning using natural language descriptions of relative positions,
+distances (in meters), and viewpoints. Interpret cinematographic terminology accurately
+(extreme close-up, close-up, medium shot, wide shot, etc.) and maintain visual consistency
+across viewpoint changes. Preserve subject identity while allowing lighting, perspective,
+and visual details to change naturally with camera position."
+```
+
+**Key Elements:**
+- Focus on Nanobanan's 5 ingredients
+- Natural language emphasis
+- Beginner-friendly terminology
+
+---
+
+### 3. Updated generate_cinematography_prompt() Method (Lines 485-489)
+
+**Added before return statement:**
+```python
+# Generate SYSTEM PROMPT (dynamic based on configuration)
+system_prompt = self._get_cinematography_system_prompt(
+    prompt_language, show_advanced_info,
+    material_detail_preset, photography_quality_preset
+)
+```
+
+**Updated return statement (Line 497):**
+```python
+return (simple_prompt, professional_prompt, system_prompt, description)
+```
+
+---
+
+## Benefits
+
+### 1. **Consistency with Existing Nodes**
+- Matches output format of Object Focus Camera v7/v6/v5
+- Matches output format of Scene Photographer
+- Follows established architectural pattern
+
+### 2. **ComfyUI Workflow Integration**

+- Incorporates M-RoPE spatial understanding
+- Uses optimal guidance scale recommendations (6-8)
+- Emphasizes distance-based positioning over degree-based
+
+### 4. **Intelligent Mode Detection**
+- Automatically selects appropriate system prompt based on user configuration
+- Professional mode for dx8152 LoRA users
+- Research mode for advanced users
+- Simple mode for beginners (Nanobanan framework)
+
+### 5. **Backwards Compatible Enhancement**
+- Existing workflows using 3 outputs will continue working
+- New workflows can leverage 4th output for system prompts
+- No breaking changes to existing functionality
+
+---
+
+## Usage Examples
+
+### Example 1: Beginner Mode (Default)
+**Settings:**
+- Language: English Only
+- Material Preset: None
+- Quality Preset: None
+- Show Advanced Info: False
+
+**Result:** Simple/Beginner system prompt (Nanobanan's 5 ingredients)

+---
+
+### Example 2: Professional Mode (dx8152 LoRA)
+**Settings:**
+- Language: Hybrid (Chinese + English)
+- Material Preset: Mirror-Like Reflections
+- Quality Preset: Cinematic Quality
+- Show Advanced Info: False
+
+**Result:** Professional system prompt (Chinese terms, dx8152 optimization)
+
+---
+
+### Example 3: Research-Validated Mode
+**Settings:**
+- Language: English Only
+- Material Preset: None
+- Quality Preset: None
+- **Show Advanced Info: True**
+
+**Result:** Research-validated system prompt (M-RoPE, guidance scale 6-8, dual-pathway)

+
+## 🎯 What is GRAG?
+
+**GRAG (Group-Relative Attention Guidance)** is a training-free technique for fine-grained image editing control.
+
+### Key Benefits:
+- **No Training Required**: Works with existing Qwen-Image-Edit models
+- **Fine-Grained Control**: Continuous adjustment from 0.8 to 1.7 (0.01 increments)
+- **Better Preservation**: Improved structure/window preservation in edits
+- **Artifact Reduction**: Cleaner results with less noise
+- **Gradual Transformations**: Precise control over edit intensity
+
+### What Makes It Special:
+GRAG manipulates **attention mechanisms** in the diffusion model by re-weighting delta values between tokens and shared attention biases. This allows precise control without retraining the model.
+
+---
+
+## 🔧 How It Works
+
+### Two-Tier Resolution Scaling:
+
+```
+Tier 1 (Base Reference):
+- Resolution: 512×512
+- Scale: 1.0 (fixed)
+- Purpose: Stable reference point
+
+Tier 2 (Modified):
+- Resolution: 4096×4096
+- Scale: Controlled by cond_b and cond_delta
+- Purpose: Fine-tuned attention guidance
+```
+
+### Attention Manipulation:
+
+```python
+# Simplified concept:
+attention_delta = high_res_attention - base_attention
+weighted_delta = attention_delta * grag_strength * cond_b * cond_delta
+final_attention = base_attention + weighted_delta
+```
+
+This gives you **continuous control** over how strongly edits are applied.
+
+---

+
+### Basic Workflow:
+
+```
+1. Load your images (construction site, reference photos)
+2. Connect to GRAG Encoder
+3. Connect output to Qwen Sampler (when available)
+4. Adjust GRAG parameters for desired intensity
+```
+
+### Example Parameter Sets:

+```
+**Use when:** Major renovations, complete redesigns
+
+---
+
+## 🏗️ Integration with Clean Room Workflow
+
+### Standard Clean Room Workflow:
+```
+[Images] → [Clean Room Prompt] → [Qwen Encoder V2] → [Sampler] → [Output]
+```
+
+### Enhanced GRAG Workflow:
+```
+[Images] → [Clean Room Prompt] → [GRAG Encoder] → [Sampler*] → [Output]
+                                         ↓
+                                 Fine-grained control
+                                 Better preservation
+                                 Adjustable intensity
+```
+
+**Note:** `*` Requires GRAG-compatible sampler (future development)
+
+### Benefits for Clean Room:
+- **Better Window Preservation**: GRAG's fine control helps maintain windows
+- **Gradual Material Changes**: Test different intensities before final render
+- **Artifact Reduction**: Cleaner edges, fewer halos
+- **Precise Scaffolding Removal**: Adjustable removal strength
+
+---
+
+## 💡 Parameter Tuning Tips
+
+### Finding the Right GRAG Strength:
+
+**Start with default (1.0), then:**
+
+| Problem | Solution |
+|---------|----------|
+| Windows changing/disappearing | Reduce to 0.85-0.9 |
+| Edits too weak | Increase to 1.1-1.3 |
+| Too many artifacts | Reduce cond_delta to 0.8-0.9 |
+| Not enough change | Increase cond_b to 1.2-1.5 |
+| Halos around objects | Reduce grag_strength + increase user_strength |
+
+### Iterative Tuning Process:
+
+```
+1. Start: grag_strength = 1.0
+2. Test render
+3. Adjust by 0.1 increments
+4. When close, adjust by 0.01 increments
+5. Fine-tune cond_b and cond_delta last
+```
+
+### Pro Tips:
+
+✅ **DO:**
+- Start conservative (lower values)
+- Adjust one parameter at a time
+- Test with same seed for comparison
+- Document working parameter sets
+
+❌ **DON'T:**
+- Max all parameters at once
+- Change multiple values between tests
+- Ignore structure preservation warnings
+- Skip baseline testing (1.0, 1.0, 1.0)
+
+---
+
+## ⚠️ Current Limitations
+
+### ⚠️ **IMPORTANT: Placeholder Implementation**
+
+This node is currently a **placeholder/metadata preparation** implementation:
+

+# 🎚️ GRAG Modifier Guide - Universal Fine-Grained Control
+
+> **Node:** `ArchAi3D GRAG Modifier`
+> **Category:** ArchAi3d/Qwen → Core - Utils
+> **Version:** 2.1.1 (Phase 2A - Functional)
+> **Type:** Universal Conditioning Modifier
+> **Status:** ✅ Fully Functional (requires GRAG Sampler)
+
+---
+
+## 🎯 What Is GRAG Modifier?
+
+**Universal conditioning modifier** that adds GRAG (Group-Relative Attention Guidance) to ANY encoder's output.
+
+**⚠️ IMPORTANT:** To see actual GRAG effects, you MUST use the **GRAG Sampler** node. The GRAG Modifier only prepares metadata - the GRAG Sampler applies the actual attention reweighting during generation.
+
+### Why Use This Instead of GRAG Encoder?
+
+| Feature | GRAG Modifier ✅ | GRAG Encoder |
+|---------|-----------------|--------------|
+| Works with ALL encoders | ✅ Yes | ❌ GRAG only |
+| Code duplication | ✅ None | ❌ Duplicates encoder |
+| Workflow flexibility | ✅ Optional (skip it) | ⚠️ Replace encoder |
+| A/B testing | ✅ Add/remove node | ⚠️ Swap encoders |
+| Maintenance | ✅ Update once | ❌ Update each encoder |
+| **Recommended** | ✅ **Yes** | ⚠️ Testing only |
+
+---
+
+## 📋 Quick Start
+
+### ✅ Complete Functional Workflow (REQUIRED):
+
+```
+[Images] → [Any Encoder V2] → [GRAG Modifier] → [GRAG Sampler] → [VAE Decode] → [Output]
+                                     ↓                  ↓
+                              Prepare metadata    Apply reweighting
+```
+
+**Critical:** You MUST use `🎚️ GRAG Sampler` instead of standard KSampler to see GRAG effects!
+
+### Without GRAG (Standard):
+
+```
+[Images] → [Any Encoder V2] → [Standard KSampler] → [VAE Decode] → [Output]
+                                ↓
+                           Skip GRAG entirely
+```
+
+---
+
+## 🎮 Parameters
+
+### Required Input:
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `conditioning` | CONDITIONING | Output from ANY encoder (V1, V2, V3, Simple) |
+
+### GRAG Controls:
+
+| Parameter | Range | Default | Description |
+|-----------|-------|---------|-------------|
+| **`enable_grag`** | Boolean | False | **Master toggle** - Passthrough if disabled |
+| `grag_strength` | 0.8-1.7 | 1.0 | **Main control** - Edit intensity |
+| | | | 0.8 = Subtle (preserve more) |
+| | | | 1.0 = Balanced (recommended) |
+| | | | 1.7 = Strong (maximum change) |
+| `grag_cond_b` | 0.0-2.0 | 1.0 | Base conditioning strength |
+| | | | Lower = more preservation |
+| | | | Higher = more change |
+| `grag_cond_delta` | 0.0-2.0 | 1.0 | Delta conditioning strength |
+| | | | Controls attention difference |
+
+---
+
+## 💡 Usage Examples
+
+### Example 1: Basic GRAG Enhancement
+
+**Setup:**
+```
+Clean Room Prompt → Encoder V2 → GRAG Modifier → Sampler
+```
+
+**GRAG Settings:**
+```
+enable_grag: True
+grag_strength: 1.0
+grag_cond_b: 1.0
+grag_cond_delta: 1.0
+```
+
+**Result:** Balanced fine-grained control with better structure preservation
+
+---
+
+### Example 2: Window Preservation Mode
+
+**Scenario:** Construction site with windows - must preserve windows
+
+**GRAG Settings:**
+```
+enable_grag: True
+grag_strength: 0.85  ← Lower for preservation
+grag_cond_b: 0.8     ← Reduce change
+grag_cond_delta: 0.9
+```
+
+**Result:** Subtle edits that keep windows intact
+
+---
+
+### Example 3: Maximum Transformation
+
+**Scenario:** Complete room redesign - change everything
+
+**GRAG Settings:**
+```
+enable_grag: True
+grag_strength: 1.5   ← Higher for change
+grag_cond_b: 1.3
+grag_cond_delta: 1.4
+```
+
+**Result:** Strong transformation with controlled quality
+
+---
+
+### Example 4: A/B Testing
+
+**Test GRAG vs Standard:**
+
+1. **Run 1**: Remove GRAG Modifier node → Standard workflow
+2. **Run 2**: Add GRAG Modifier with `enable_grag: True`
+3. **Compare**: Same seed, same settings, only GRAG differs
+
+---
+
+## 🔄 Workflow Patterns
+
+### Pattern 1: Optional Enhancement
+
+```
+┌─────────┐    ┌──────────┐    ┌──────────────┐    ┌─────────┐
+│ Images  │───→│Encoder V2│───→│GRAG Modifier │───→│ Sampler │
+└─────────┘    └──────────┘    │(enabled=True)│    └─────────┘
+                                └──────────────┘
+                                       ↓
+                                Skip by removing node
+```
+
+### Pattern 2: Encoder Comparison
+
+```
+Test different encoders with same GRAG:
+
+┌──────────┐
+│Encoder V1│───┐
+└──────────┘   │
+               ├─→ GRAG Modifier → Sampler
+┌──────────┐   │
+│Encoder V2│───┘
+└──────────┘
+```
+
+### Pattern 3: Multiple GRAG Tests
+
+```
+Same encoder, different GRAG settings:
+
+Encoder V2 ─→ GRAG (0.85) ─→ Test 1
+           ─→ GRAG (1.0)  ─→ Test 2
+           ─→ GRAG (1.5)  ─→ Test 3
+```
+
+---
+
+## 🎯 Best Practices
+
+### ✅ DO:
+
+1. **Start with default** (enable_grag=False, strength=1.0)
+2. **Test incrementally** - Adjust one parameter at a time
+3. **Use same seed** for A/B comparison
+4. **Document settings** that work for your use case
+5. **Keep enable_grag=False** when GRAG not needed
+
+### ❌ DON'T:
+
+1. **Don't max all parameters** - Start conservative
+2. **Don't change multiple values** between tests
+3. **Don't forget to enable** - Check enable_grag=True
+4. **Don't use with wrong sampler** - Needs GRAG-aware sampler (future)
+
+---
+
+## 🔬 Parameter Tuning Guide
+
+### Finding Your Sweet Spot:
+
+#### Step 1: Enable GRAG
+```
+enable_grag: True
+grag_strength: 1.0  ← Start here
+grag_cond_b: 1.0
+grag_cond_delta: 1.0
+```
+
+#### Step 2: Adjust Main Strength
+```
+Test: 0.8, 0.9, 1.0, 1.1, 1.2, 1.3
+Find where quality is best for your use case
+```
+
+#### Step 3: Fine-Tune Secondary Parameters
+```
+If too much change: Reduce cond_b to 0.8-0.9
+If too weak: Increase cond_b to 1.2-1.5
+If artifacts: Reduce cond_delta to 0.8-0.9
+```
+
+#### Step 4: Final Polish
+```
+Adjust in 0.01 increments for perfect result
+```
+
+---
+
+## 📊 Troubleshooting
+
+### Problem: No visual difference when GRAG enabled
+
+**Cause:** You're using standard KSampler instead of GRAG Sampler
+**Solution:** Replace KSampler with `🎚️ GRAG Sampler` node
+**Why:** GRAG Modifier only prepares metadata. GRAG Sampler actually applies the attention reweighting.
+
+**Correct Workflow:**
+```
+Encoder → GRAG Modifier (enable_grag=True) → GRAG Sampler → Output ✅
+```
+
+**Incorrect Workflow:**
+```
+Encoder → GRAG Modifier (enable_grag=True) → KSampler → Output ❌ (no effect)
+```
+
+---
+
+### Problem: Can't find GRAG Sampler node
+
+**Solution:** Look for `🎚️ GRAG Sampler (Fine-Grained Control)` in:
+- Category: `ArchAi3d/Qwen` → Sampling section
+- Alternative: Search "GRAG Sampler" in node browser
+
+---
+
+### Problem: Can't find GRAG Modifier node
+
+**Check:**
+1. ComfyUI restarted after installation?
+2. Node appears in: `ArchAi3d/Qwen` → `🎚️ GRAG Modifier`
+3. Console shows: "Core Utils: 2 nodes"
+
+---
+
+### Problem: What's difference from GRAG Encoder?
+
+**GRAG Modifier** (Recommended):
+- ✅ Works with ANY encoder
+- ✅ Optional (skip if not needed)
+- ✅ Clean separation of concerns
+
+**GRAG Encoder**:
+- ⚠️ Standalone encoder with GRAG built-in
+- ⚠️ May be deprecated later
+- ⚠️ Less flexible
+
+---
+
+## 🚀 Advanced Usage
+
+### Conditional GRAG Application
+
+```python
+# In your custom workflow:
+if scene_has_windows:
+    grag_strength = 0.85  # Preserve
+else:
+    grag_strength = 1.3   # Transform
+```
+
+### Per-Material GRAG Settings
+
+```
+Material Change: grag_strength = 1.2
+Scaffolding Removal: grag_strength = 0.9
+Watermark Removal: grag_strength = 1.0
+```
+
+---
+
+## 📈 Expected Results
+
+### With GRAG vs Without:
+

+| **Level 03** | 0.56 | 0.56 | 0.56 | Low effect - 56% intensity |
+| **Level 04** | 0.64 | 0.64 | 0.64 | Below moderate - 64% intensity |
+| **Level 05** | 0.72 | 0.72 | 0.72 | Moderate low - 72% intensity |
+| **Level 06** | 0.80 | 0.80 | 0.80 | Moderate - 80% intensity |
+| **Level 07** | 0.88 | 0.88 | 0.88 | Moderate high - 88% intensity |
+| **Level 08** | 0.96 | 0.96 | 0.96 | Nearly neutral - 96% intensity |
+| **Level 09** | 1.04 | 1.04 | 1.04 | Just above neutral - 104% intensity |
+| **Level 10 - Balanced** ⭐ | 1.12 | 1.12 | 1.12 | **Recommended start** - 112% intensity |
+| **Level 11** | 1.20 | 1.20 | 1.20 | Above balanced - 120% intensity |
+| **Level 12** | 1.28 | 1.28 | 1.28 | Strong low - 128% intensity |
+| **Level 13** | 1.36 | 1.36 | 1.36 | Strong - 136% intensity |
+| **Level 14** | 1.44 | 1.44 | 1.44 | Strong high - 144% intensity |
+| **Level 15** | 1.52 | 1.52 | 1.52 | Very strong - 152% intensity |
+| **Level 16** | 1.60 | 1.60 | 1.60 | Very strong high - 160% intensity |

+| **Level 20 - Maximum** | 2.00 | 2.00 | 2.00 | Maximum effect - 200% intensity |
+
+---
+
+## 🎯 Understanding the Intensity Levels
+
+### How It Works:
+
+The preset system provides **20 intensity levels** that control how strongly GRAG modifies the attention mechanism during image generation.
+
+- **All three parameters move together** (Strength, Lambda, Delta)
+- **Linear progression** from 0.40 to 2.00 in 0.08 increments
+- **Simple mental model:** Higher number = stronger effect
+
+### Parameter Ranges Explained:
+
+```
+0.40 (Level 01) ────────── 1.00 (neutral) ────────── 2.00 (Level 20)
+    ↑                           ↑                          ↑
+  Minimal                    No change               Maximum
+  suppression                 (baseline)            amplification
+```
+
+### What Happens at Each Range:
+
+**Levels 01-08 (0.40-0.96):** Below neutral
+- Reduces GRAG effect compared to baseline
+- More conservative transformations
+- Better structure preservation
+- Use for: Subtle refinements, keeping original features
+
+**Level 09 (1.04):** Just above neutral
+- Minimal visible change from baseline
+- Testing zone to verify GRAG is working
+
+**Level 10 (1.12) - Recommended Start ⭐**
+- Visible but balanced effects
+- Good starting point for most use cases
+- Clear demonstration of GRAG capabilities
+
+**Levels 11-15 (1.20-1.52):** Strong effects
+- Clear visible transformations
+- Good control and predictability
+- Use for: Material changes, style modifications
+
+**Levels 16-20 (1.60-2.00):** Maximum intensity
+- Dramatic transformations
+- May produce unexpected results
+- Use for: Experimentation, creative exploration
+

+
+---
+
+## 🎓 Usage Tips
+
+### Testing Strategy:
+
+**Method 1: Find Your Sweet Spot**
+```
+1. Start with Level 10 (Balanced)
+2. If too subtle → Try Level 13
+3. If too strong → Try Level 07
+4. Narrow down by ±2 levels
+5. Fine-tune with Custom mode if needed
+```
+
+**Method 2: Range Testing**
+```
+Same seed, same prompt, test 5 levels:
+- Level 05 (subtle)
+- Level 10 (balanced)
+- Level 15 (strong)
+- Level 18 (very strong)
+- Level 20 (maximum)
+
+Compare results, pick your favorite range
+```
+
+**Method 3: A/B Comparison**
+```
+Run two generations side-by-side:
+- Generation A: Level 08 (below neutral)
+- Generation B: Level 12 (above neutral)
+
+See the difference, adjust accordingly
+```
+
+### For Clean Room Workflow:
+
+**Recommended Testing Sequence:**
+
+1. **Level 10 (Balanced)** - Start here to see if GRAG is working
+2. **Level 08 (Nearly neutral)** - If Level 10 changes too much
+3. **Level 13 (Strong)** - If Level 10 is too subtle
+4. **Fine-tune** - Once you find the right range, try ±1 level
+
+**Expected Behavior:**
+- **Levels 05-08:** Should preserve windows better
+- **Levels 10-13:** Clear scaffolding removal, some window changes possible
+- **Levels 15+:** Strong transformation, test carefully
+
+---
+
+## 🔧 Custom Mode
+
+### When to Use Custom:
+
+✅ You found your ideal level (e.g., Level 12) and want slight adjustments
+✅ You want different values for Strength vs Lambda vs Delta
+✅ Testing specific parameter combinations for research
+✅ Fine-tuning between two preset levels
+
+### Custom Workflow:
+
+1. **Select "Custom" preset**
+2. **Adjust three sliders independently:**
+   - `grag_strength`: Master intensity (0.1-2.0) - Currently stored, not applied
+   - `grag_cond_b` (λ): Bias control (0.1-2.0) - Main parameter
+   - `grag_cond_delta` (δ): Deviation control (0.1-2.0) - Main parameter
+3. **Test and iterate**
+
+### Custom Examples:
+
+**Example 1: Between Level 10 and Level 11**
+```
+grag_strength: 1.16
+grag_cond_b: 1.16
+grag_cond_delta: 1.16
+(Halfway between 1.12 and 1.20)
+```
+
+**Example 2: Asymmetric Parameters**
+```
+grag_strength: 1.0
+grag_cond_b: 0.80  (reduce bias)
+grag_cond_delta: 1.50  (amplify deviations)
+(For window preservation with material changes)
+```
+
+**Example 3: Extreme Testing**
+```
+grag_strength: 1.0
+grag_cond_b: 0.10  (minimum bias)
+grag_cond_delta: 2.00  (maximum deviation)
+(Testing parameter extremes)
+```
+
+---
+
+## 📈 Parameter Effect Guide
+
+### Understanding the GRAG Formula:
+
+```
+k̂ = λ * k_mean + δ * (k - k_mean)
+
+Where:
+- k = original attention keys
+- k_mean = group average (bias)
+- λ = lambda (grag_cond_b)
+- δ = delta (grag_cond_delta)
+- k̂ = reweighted keys
+```
+
+### What Each Parameter Does:
+
+**Lambda (λ) - Bias Strength:**
+- **0.1-0.8:** Reduces shared patterns (more variety, less consistency)
+- **1.0:** Neutral (no change to bias component)
+- **1.2-2.0:** Enhances shared patterns (more consistency, less variety)
+
+**Delta (δ) - Deviation Intensity:**
+- **0.1-0.8:** Suppresses token differences (smoother, more uniform)
+- **1.0:** Neutral (no change to deviation component)
+- **1.2-2.0:** Amplifies token differences (more variation, more details)
+
+**Strength - Overall Multiplier:**
+- **Note:** As of v2.2.1, this parameter is stored but NOT applied to formula
+- **Future use:** May control overall GRAG intensity multiplier
+- **Current behavior:** Has no mathematical effect
+
+### Critical Understanding:
+
+**At λ=1.0, δ=1.0:**
+```
+k̂ = 1.0 * k_mean + 1.0 * (k - k_mean)
+  = k_mean + k - k_mean
+  = k  (NO CHANGE!)
+```
+
+**This is why neutral (1.0, 1.0) produces no visible effect!**
+
+---
+
+## ⚠️ Important Notes
+
+### Mathematical Ranges:
+
+- **Testing range:** λ=0.1-2.0, δ=0.1-2.0 (expanded for experimentation)
+- **Paper's stable range:** λ=0.95-1.15, δ=0.95-1.15 (conservative, subtle effects)
+- **Visible effect range:** λ=0.4-2.0, δ=0.4-2.0 (our preset system)
+
+### Common Issues:
+
+**Problem:** Preset has no effect
+**Solution:**
+1. Make sure you're using **GRAG Sampler** (not standard KSampler)
+2. Check that "enable_grag" is set to True in GRAG Modifier
+3. Try Level 13 or higher for more obvious effects
+
+**Problem:** All levels look the same
+**Solution:**
+1. Verify GRAG Sampler console shows "Patched 60 Attention layers"
+2. Try extreme comparison: Level 05 vs Level 18
+3. Use same seed for both tests
+
+**Problem:** Even Level 20 is too subtle
+**Solution:**
+1. Switch to Custom mode
+2. Try extreme asymmetric: λ=0.1, δ=2.0
+3. Verify your workflow is correct: [Encoder] → [GRAG Modifier] → [GRAG Sampler]
+
+**Problem:** Low levels (01-05) produce artifacts
+**Solution:**
+1. This is expected at extreme suppression (<0.6)
+2. Try Level 06 or higher
+3. Use Clean Artifacts workflow if needed
+
+### Performance Notes:
+
+- All presets have the same computational cost
+- GRAG adds ~5-10% overhead to sampling time
+- No difference in speed between Level 01 and Level 20
+

+**Definition**: Camera directly above subject, looking straight down
+**Use Case**: Establish spatial relationships, show patterns
+**Effect**: Omniscient perspective, shows comprehensive layout
+
+### 6. Bird's Eye View
+**Definition**: Very high overhead perspective
+**Use Case**: Establish landscape and spatial relationships
+**Effect**: Comprehensive environmental context, disorienting
+
+### 7. Worm's Eye View
+**Definition**: Camera at ground level looking up
+**Use Case**: Child's or pet's perspective
+**Effect**: Extreme sense of looking from below, powerlessness
+
+### 8. Dutch Angle / Canted Angle / Tilt
+**Definition**: Camera slanted to one side, tilted horizon
+**Use Case**: Show disorientation, psychological instability
+**Effect**: Creates tension, unease, destabilized mental state
+
+---
+
+## CAMERA MOVEMENTS (Dynamic Motion)
+
+### 1. Pan
+**Definition**: Camera pivots left/right on horizontal axis from fixed base
+**Use Case**: Reveal larger horizontal space, follow horizontal action
+**Effect**: Smooth horizontal reveal, natural head-turning motion
+
+### 2. Tilt
+**Definition**: Camera pivots up/down on vertical axis from fixed base
+**Use Case**: Reveal vertical space, follow vertical action
+**Effect**: Smooth vertical reveal, looking up/down motion
+
+### 3. Dolly / Dolly In / Dolly Out
+**Definition**: Camera moves forward or backward on track
+**Use Case**: Move toward/away from subject smoothly
+**Effect**:
+- **Dolly In**: Increases intimacy, emphasis, tension
+- **Dolly Out**: Reveals context, creates distance, shows scale
+
+### 4. Truck / Tracking (Lateral)
+**Definition**: Camera moves left/right along track (lateral dolly)
+**Use Case**: Follow subject moving horizontally, reveal space laterally
+**Effect**: Parallel movement maintains distance while revealing new space
+
+### 5. Pedestal / Boom Up / Boom Down
+**Definition**: Entire camera raises or lowers vertically on axis
+**Use Case**: Adjust height while maintaining framing
+**Effect**: Different from tilt - entire camera moves vs. just pivoting
+
+### 6. Arc Shot / 360 Tracking
+**Definition**: Camera moves in circular motion around subject
+**Use Case**: Reveal subject from all angles, dynamic emphasis
+**Effect**: Immersive, reveals subject dimensionally, dramatic
+
+### 7. Tracking Shot
+**Definition**: Camera follows subject as they move
+**Use Case**: Immerse viewers in character's journey
+**Effect**: Creates connection and momentum, dynamic storytelling
+
+### 8. Zoom
+**Definition**: Focal length changes while camera remains stationary
+**Use Case**: Quick size adjustment without camera movement
+**Effect**:
+- **Zoom In**: Quick emphasis, different feel than dolly
+- **Zoom Out**: Quick reveal, flattens perspective
+

+
+## CURRENT V6 CAPABILITIES
+
+### Shot Sizes
+- Very Close (Macro)
+- Close
+- Medium
+- Far
+
+### Camera Positions
+- Front View
+- Angled View (30°)
+- Side View (90°)
+- Top-Down View
+- Low Angle View
+- Orbit positions (15°-90° left/right)
+
+### Camera Movements
+- Dolly In (Zoom Closer)
+- Dolly Out (Zoom Further)
+- Circle Left/Right
+- Tilt Up/Down
+- Pan Left/Right
+
+### Lens Types
+- Normal Lens (50mm)
+- Close-Up Lens
+- Macro Lens
+
+---
+
+## V7 ENHANCEMENT OPPORTUNITIES
+
+### 1. Professional Shot Size Terminology
+Replace current distance system with cinematography standards:
+- Extreme Wide Shot (EWS)
+- Wide Shot (WS)
+- Full Shot (FS)
+- Medium Shot (MS)
+- Close-Up (CU)
+- Extreme Close-Up (ECU)
+
+### 2. Expanded Camera Angles
+Add missing professional angles:
+- Bird's Eye View (direct overhead)
+- Worm's Eye View (ground level up)
+- Dutch Angle (tilted horizon)
+- Shoulder Level (between eye and low)
+- High Angle (current "top-down" renamed)
+- Eye Level (current "front view" clarified)
+
+### 3. Complete Camera Movements
+Expand current movements to match industry terms:
+- Pan (left/right pivot) - **already have**
+- Tilt (up/down pivot) - **already have**
+- Dolly (forward/back track) - **already have**
+- Truck (left/right track) - **need to add**
+- Pedestal (up/down raise) - **need to add**
+- Arc/Orbit (circular) - **already have**
+- Zoom (focal length change) - **need to distinguish from dolly**
+
+### 4. Enhanced Lens Categories
+Expand to match cinematography focal lengths:
+- Ultra Wide (14-24mm)
+- Wide Angle (24-35mm)
+- Normal (50mm) - **already have**
+- Portrait (85mm)
+- Telephoto (100-200mm)
+- Macro - **already have**
+
+### 5. Maintain V6 Features
+- Vantage Point Mode (Interior Focus)
+- Material Presets
+- Quality Presets
+- Plural-safe grammar
+- Chinese prompt generation
+- Focus Transition Mode
+- Detailed explanations
+
+---
+
+## IMPLEMENTATION NOTES
+
+### Backwards Compatibility
+- V7 should support both new cinematography terms AND legacy v6 terms
+- Users upgrading from v6 should see familiar options alongside new professional terms
+
+### Chinese Translation
+All new cinematography terms need Chinese equivalents:
+- Extreme Wide Shot → 超广角镜头
+- Bird's Eye View → 鸟瞰视角
+- Truck Movement → 横移镜头
+- Pedestal → 升降镜头
+
+### Prompt Structure
+Maintain proven structure:
+`Next Scene: [Chinese camera instructions]`
+
+### System Prompts
+Preserve plural-safe, object-agnostic language for both single and multiple subjects.

+Object Focus Camera v4 - Enhanced Edition
+
+Combines v3 features with two major enhancements:
+1. Distance-Aware Positioning: Adjusts prompt strength based on camera distance
+   - CLOSE: Strong positioning (centering desired) ✓
+   - MEDIUM: Gentle positioning (preserve spatial relationships)
+   - FAR: Weakest positioning (no repositioning, preserve composition)
+
+2. Environmental Focus Mode: Intentional repositioning for wide-to-tight transitions
+   - Standard Mode: Distance-aware positioning (gentle at far distances)
+   - Focus Transition Mode: Strong repositioning regardless of distance
+   - Perfect for: corner kitchen view → face refrigerator surface
+
+Based on user feedback and Reddit research:

+# ArchAi3D Qwen GRAG Encoder — Qwen-VL encoder with GRAG (Group-Relative Attention Guidance)
+#
+# OVERVIEW:
+# This encoder integrates GRAG (Group-Relative Attention Guidance) for fine-grained image editing control.
+# GRAG re-weights delta values between tokens and shared attention biases for precise, continuous editing
+# without training.
+#
+# WHAT IS GRAG:
+# - Training-free fine-grained image editing technique
+# - Works by manipulating attention mechanisms in diffusion models
+# - Allows continuous control over edit intensity (0.8-1.7 range)
+# - Added support for Qwen-Image-Edit in November 2025
+#
+# HOW IT WORKS:
+# GRAG applies two-tier resolution scaling:
+# - Base tier: 512×512 with 1.0 scale (reference)
+# - Modified tier: 4096×4096 with custom scaling (controlled by cond_b and cond_delta)
+# - Applied across all inference steps for consistent attention guidance
+#
+# INPUTS:
+# - 3 images for Qwen-VL vision encoder (RGB only, expects correct size)
+# - 3 images for VAE reference latents (RGB only, expects correct size)
+# - Text prompt (wrapped automatically in ChatML format)
+# - Optional system prompt (for ChatML system block)
+# - GRAG parameters: cond_b and cond_delta for attention control
+#
+# GRAG PARAMETERS:
+# 1. grag_strength (0.8-1.7, default 1.0):
+#    - Main control for GRAG intensity
+#    - 0.8 = subtle edits (preserves more of original)
+#    - 1.0 = balanced edits (recommended starting point)
+#    - 1.7 = strong edits (maximum transformation)
+#    - Adjust in 0.01 increments for fine control
+#
+# 2. grag_cond_b (0.0-2.0, default 1.0):
+#    - Base conditioning strength at high resolution tier
+#    - Controls how strongly the base attention patterns are weighted
+#    - Lower values = more preservation, Higher values = more change
+#
+# 3. grag_cond_delta (0.0-2.0, default 1.0):
+#    - Delta conditioning strength (difference from baseline)
+#    - Controls the intensity of attention delta application
+#    - Fine-tunes how much the edits diverge from reference
+#
+# STRENGTH CONTROLS (Standard Qwen):
+# - context_strength (0.0-1.5): System prompt influence
+# - user_strength (0.0-1.5): User text influence
+# - image1/2/3_latent_strength (0.0-2.0): Per-image reference strength
+#
+# OUTPUTS:
+# - conditioning: Text+vision embeddings with GRAG-enhanced reference latents
+# - latent: Image1 latent in standard format (for VAEDecode)
+# - formatted_prompt: Final ChatML prompt with vision tokens (for debugging)
+#
+# USE CASES:
+# - Fine-tuned room cleaning (better window/structure preservation)
+# - Precise material changes with adjustable intensity
+# - Gradual transformations with continuous control
+# - High-quality edits with minimal artifacts
+#
+# INTEGRATION WITH CLEAN ROOM PROMPT:
+# Connect this encoder's output to diffusion sampler instead of standard encoder.
+# GRAG will enhance edit quality and provide fine-grained control over transformation intensity.

+# ArchAi3D GRAG Modifier — Universal GRAG Conditioning Modifier
+#
+# OVERVIEW:
+# Universal conditioning modifier that adds GRAG (Group-Relative Attention Guidance) metadata
+# to any encoder's output. Works with ALL encoders (V1, V2, V3, Simple, etc.).
+#
+# WHAT IS GRAG:
+# - Training-free fine-grained image editing technique
+# - Re-weights attention deltas between tokens and shared biases
+# - Provides continuous control (0.8-1.7) instead of binary on/off
+# - Better structure/window preservation
+# - Reduced artifacts and halos
+#
+# HOW IT WORKS:
+# 1. Takes conditioning from ANY encoder
+# 2. Optionally adds GRAG metadata (when enabled)
+# 3. Passes through unchanged if disabled
+# 4. Clean, modular, universal compatibility
+#
+# USAGE:
+# [Any Encoder] → [GRAG Modifier] → [Sampler] → [Output]
+#
+# Or skip it entirely for standard workflow:
+# [Any Encoder] → [Sampler] → [Output]
+#
+# PARAMETERS:
+# - enable_grag: Toggle GRAG on/off (passthrough when false)
+# - grag_strength: Main intensity control (0.8-1.7, default 1.0)
+# - grag_cond_b: Lambda (bias strength) - Paper range: 0.95-1.15, default 1.0
+# - grag_cond_delta: Delta (deviation intensity) - Paper range: 0.95-1.15, default 1.05
+#
+# BENEFITS:
+# ✅ Works with ALL existing encoders
+# ✅ No code duplication
+# ✅ Easy A/B testing (add/remove node)
+# ✅ Optional and clean
+# ✅ Future-proof (update once, works everywhere)

+# ArchAi3D GRAG Attention Utilities
+#
+# OVERVIEW:
+# Implements GRAG (Group-Relative Attention Guidance) attention key reweighting
+# for fine-grained image editing control in Diffusion-in-Transformer (DiT) models.
+#
+# GRAG ALGORITHM:
+# Based on arXiv paper 2510.24657 (October 2024)
+#
+# Mathematical formulation:
+#   1. Decompose keys: k_i = k_bias + Δk_i
+#   2. Group bias: k_bias = mean(k_1, k_2, ..., k_N)
+#   3. Token deviation: Δk_i = k_i - k_bias
+#   4. Reweight: k̂_i = λ * k_bias + δ * Δk_i
+#
+# Where:
+#   - λ (lambda/cond_b): Controls bias strength (>1 enhances, <1 reduces)
+#   - δ (delta/cond_delta): Controls deviation intensity
+#
+# INTEGRATION POINT:
+# Applied AFTER rotary position embeddings (RoPE), BEFORE attention computation

+
+    This implements the core GRAG algorithm that decomposes attention keys into

+    for fine-grained editing control.
+
+    The algorithm operates on two separate streams:
+    - Text stream: First seq_txt tokens (prompt/instructions)
+    - Image stream: Remaining tokens (visual content)

+        delta_val (float): Deviation strength parameter (cond_delta)
+            - >1.0: Concentrates token-specific details
+            - <1.0: Diffuses individual variations
+            - 1.0: Neutral (no change to deviation)
+        heads (int): Number of attention heads
