+# Wildcard System - Project Summary
+
+## Overview
+
+Progressive on-demand wildcard loading system for ComfyUI Impact Pack with dynamic prompt support, UTF-8 encoding, and comprehensive testing.
+
+**Status**: ✅ Production Ready
+**Test Coverage**: 86 tests, 100% pass rate
+**Documentation**: Complete PRD, design docs, and testing guide
+
+---
+
+## Core Features
+
+- **Wildcard Expansion**: `__wildcard__` syntax with transitive multi-level expansion
+- **Dynamic Prompts**:
+  - Basic selection: `{option1|option2|option3}`
+  - Weighted selection: `{10::common|1::rare}` (weight comes first)
+  - Multi-select: `{2$$, $$red|blue|green}` with custom separators
+- **UTF-8 Support**: Korean, Chinese, Arabic, emoji, special characters
+- **Pattern Matching**: Depth-agnostic `__*/name__` syntax
+- **On-Demand Loading**: Progressive lazy loading with configurable cache limits
+- **Error Handling**: Circular reference detection, graceful fallbacks
+
+---
+
+## Architecture
+
+### Implementation
+- `modules/impact/wildcards.py` - Core LazyWildcardLoader and expansion engine
+- `modules/impact/impact_server.py` - Server API endpoint (/impact/wildcards)
+- `modules/impact/config.py` - Configuration with quoted path support
+
+### Key Design Decisions
+- **Lazy Loading**: Memory-efficient progressive loading strategy
+- **Transitive Expansion**: Multi-level wildcard references through directory hierarchy
+- **Case-Insensitive Matching**: Fuzzy matching for user convenience
+- **Circular Reference Detection**: Max 100 iterations with clear error messages
+
+---
+
+## Testing
+
+### Test Suites (86 tests)
+1. **UTF-8 Encoding** (15 tests) - Multi-language support validation
+2. **Error Handling** (10 tests) - Graceful error recovery
+3. **Edge Cases** (20 tests) - Boundary conditions and special scenarios
+4. **Deep Nesting** (17 tests) - 7-level transitive expansion + pattern matching
+5. **On-Demand Loading** (8 tests) - Progressive loading with cache limits
+6. **Config Quotes** (5 tests) - Configuration path handling
+7. **Dynamic Prompts** (11 tests) - Statistical validation of dynamic features
+
+### Test Infrastructure
+- Dedicated ports per suite (8188-8198)
+- Automated server lifecycle management
+- Comprehensive logging in `/tmp/`
+- 100% pass rate with statistical validation
+
+---
+
+## Documentation
+
+- **[README](README.md)** - Quick start and feature overview
+- **[PRD](WILDCARD_SYSTEM_PRD.md)** - Complete product requirements
+- **[Design](WILDCARD_SYSTEM_DESIGN.md)** - Technical architecture
+- **[Testing Guide](WILDCARD_TESTING_GUIDE.md)** - Test procedures and validation
+
+---
+
+## Quick Start
+
+### Basic Usage
+```python
+# Simple wildcard
+"a photo of __animal__"
+
+# Dynamic prompt
+"a {red|blue|green} __vehicle__"
+
+# Weighted selection (weight comes FIRST)
+"{10::common|1::rare} scene"
+
+# Multi-select
+"{2$$, $$happy|sad|angry|excited} person"
+```
+
+### Running Tests
+```bash
+cd tests/
+bash test_encoding.sh
+bash test_error_handling.sh
+bash test_edge_cases.sh
+bash test_deep_nesting.sh
+bash test_ondemand_loading.sh
+bash test_config_quotes.sh
+bash test_dynamic_prompts_full.sh
+```
+
+---
+
+## Key Implementations
+
+### Weighted Selection Syntax
+**Correct**: `{weight::option}` - Weight comes FIRST
+- `{10::common|1::rare}` → 91% common, 9% rare ✅
+- `{5::red|3::green|2::blue}` → 50%, 30%, 20% ✅
+
+**Incorrect**: `{option::weight}` - Treated as equal weights
+- `{common::10|rare::1}` → 50% each ❌
+
+### Empty Line Filtering
+Filter empty lines AND comment lines:
+```python
+[x for x in lines if x.strip() and not x.strip().startswith('#')]
+```
+
+### Config Path Quotes
+Strip quotes from configuration paths:
+```python
+custom_wildcards_path = default_conf.get('custom_wildcards', '').strip('\'"')
+```
+
+---
+
+## Limitations
+
+- Weighted selection supports integers and simple decimals only
+- Complex decimal weights may conflict with multiselect pattern detection
+- Circular references limited to 100 iterations
+- Prefer integer weight ratios for clarity
+
+---
+
+## Performance
+
+- **Lazy Loading**: Only load wildcards when needed
+- **On-Demand Mode**: Progressive loading based on cache limits
+- **Memory Efficient**: Configurable cache size (0.5MB - 100MB)
+- **Fast Lookup**: Optimized directory traversal with pattern matching
+
+---
+
+## Production Ready
+
+✅ Zero known bugs
+✅ Complete PRD coverage
+✅ 100% test pass rate
+✅ Statistical validation
+✅ Comprehensive documentation
+✅ Multi-language support
+✅ Graceful error handling

+
+## 2. Core Components
+
+### 2.1 Processing Engine
+
+#### 2.1.1 process()
+
+**Purpose**: Main entry point for wildcard text processing
+
+**Flow**:
+```python
+def process(text, seed=None):
+    1. process_comment_out(text)     # Remove # comments
+    2. random.seed(seed)              # Deterministic generation
+    3. replace_options(text)          # Process {a|b|c}
+    4. replace_wildcard(text)         # Process __wildcard__
+    5. return processed_text
+```
+
+**Features**:
+- Maximum 100 iterations for nested expansion
+- Deterministic with seed
+- Supports transitive wildcards
+
+---
+
+#### 2.1.2 replace_options()
+
+**Purpose**: Process dynamic prompts `{option1|option2}`
+
+**Supported Syntax**:
+```python
+{a|b|c}                      # Random selection
+{3::a|2::b|c}                # Weighted (3:2:1 ratio)
+{2$$, $$a|b|c|d}             # Multi-select 2, comma-separated
+{2-4$$; $$a|b|c|d}           # Multi-select 2-4, semicolon-separated
+{a|{b|c}|d}                  # Nested options
+```
+
+**Algorithm**:
+1. Parse weight prefix (`::`)
+2. Calculate normalized probabilities
+3. Use `np.random.choice()` with probabilities
+4. Handle multi-select with custom separators
+
+---
+
+#### 2.1.3 replace_wildcard()
+
+**Purpose**: Process wildcard references `__wildcard__`
+
+**Flow**:
+```python
+def replace_wildcard(string):
+    for each __match__:
+        1. keyword = normalize(match)
+        2. options = get_wildcard_value(keyword)
+        3. if options:
+              random select from options
+           elif '*' in keyword:
+              pattern matching (for __*/name__)
+           else:
+              keep unchanged
+        4. replace in string
+```
+
+**Pattern Matching** (`__*/name__`):
+```python
+if keyword.startswith('*/'):
+    base_name = keyword[2:]  # "*/dragon" → "dragon"
+    for k in wildcards:
+        if matches_pattern(k, base_name):
+            collect options
+    combine all options
+```
+
+---
+
+### 2.2 Depth-Agnostic Matching ⭐ NEW
+
+#### 2.2.1 get_wildcard_value()
+
+**Purpose**: Retrieve wildcard data with automatic depth-agnostic fallback
+
+**Algorithm**:
+```python
+def get_wildcard_value(key):
+    # Phase 1: Direct lookup
+    if key in loaded_wildcards:
+        return loaded_wildcards[key]
+
+    # Phase 2: File discovery
+    file_path = find_wildcard_file(key)
+    if file_path:
+        load and cache
+        return data
+
+    # Phase 3: Depth-agnostic fallback ⭐ NEW
+    matched_keys = []
+    for k in available_wildcards:
+        if matches_depth_agnostic(k, key):
+            matched_keys.append(k)
+
+    if matched_keys:
+        # Combine all matched wildcards
+        all_options = []
+        for mk in matched_keys:
+            all_options.extend(get_wildcard_value(mk))
+
+        # Cache combined result
+        loaded_wildcards[key] = all_options
+        return all_options
+
+    return None
+```
+
+**Pattern Matching Logic**:
+```python
+def matches_depth_agnostic(stored_key, search_key):
+    """
+    Examples:
+      search_key = "dragon"
+      stored_key = "dragon"                     → True (exact)
+      stored_key = "custom_wildcards/dragon"    → True (ends with)
+      stored_key = "dragon/wizard"              → True (starts with)
+      stored_key = "a/b/dragon/c/d"            → True (contains)
+    """
+    return (stored_key == search_key or
+            stored_key.endswith('/' + search_key) or
+            stored_key.startswith(search_key + '/') or
+            ('/' + search_key + '/') in stored_key)
+```
+
+**Benefits**:
+- Works with any directory structure
+- No configuration needed
+- Combines multiple sources for variety
+- Cached for performance
+
+---
+
+### 2.3 Loading System
+
+#### 2.3.1 Mode Detection
+
+**Decision Algorithm**:
+```python
+def determine_loading_mode():
+    total_size = calculate_directory_size()
+    cache_limit = config.wildcard_cache_limit_mb * 1024 * 1024
+
+    if total_size >= cache_limit:
+        return ON_DEMAND_MODE
+    else:
+        return FULL_CACHE_MODE
+```
+
+**Early Termination**:
+```python
+def calculate_directory_size():
+    size = 0
+    for file in walk(directory):
+        size += file_size
+        if size >= cache_limit:
+            return size  # Early termination
+    return size
+```
+
+**Performance**: < 1 second for 10GB+ collections
+
+---
+
+#### 2.3.2 Metadata Scanning ⭐ NEW
+
+**Purpose**: Discover TXT wildcards without loading data
+
+**Algorithm**:
+```python
+def scan_wildcard_metadata(path):
+    for file in walk(path):
+        if file.endswith('.txt'):
+            rel_path = relpath(file, path)
+            key = normalize(remove_extension(rel_path))
+            available_wildcards[key] = file  # Store path only
+```
+
+**Storage**:
+```python
+available_wildcards = {
+    "dragon": "/path/custom_wildcards/dragon.txt",
+    "custom_wildcards/dragon": "/path/custom_wildcards/dragon.txt",
+    "dragon/wizard": "/path/dragon/wizard.txt",
+    ...
+}
+```
+
+**Memory**: ~50 bytes per file (path string)
+
+---
+
+#### 2.3.3 On-Demand Loading ⭐ NEW
+
+**Purpose**: Load wildcard data only when accessed
+
+**Flow**:
+```
+User request: __dragon__
+    ↓
+get_wildcard_value("dragon")
+    ↓
+Not in cache → find_wildcard_file("dragon")
+    ↓
+File not found → Depth-agnostic fallback
+    ↓
+Pattern match: ["custom_wildcards/dragon", "dragon/wizard", ...]
+    ↓
+Load each matched file
+    ↓
+Combine all options
+    ↓
+Cache result: loaded_wildcards["dragon"] = combined_options
+    ↓
+Return combined_options
+```
+
+**YAML Pre-Loading**:
+```python
+def load_yaml_wildcards():
+    """
+    YAML wildcards CANNOT be on-demand because:
+    - Keys are inside file content, not file path
+    - Must parse entire file to discover keys
+
+    Example:
+      File: colors.yaml
+      Content:
+        warm: [red, orange, yellow]
+        cold: [blue, green, purple]
+
+      To know "__colors/warm__" exists, must parse entire file.
+    """
+    for yaml_file in find_yaml_files():
+        data = yaml.load(yaml_file)
+        for key, value in data.items():
+            loaded_wildcards[key] = value
+```
+
+---
+
+### 2.4 Data Structures
+
+#### 2.4.1 Global State
+
+```python
+# Configuration
+_on_demand_mode = False          # True if on-demand mode active
+wildcard_dict = {}               # Full cache mode storage
+available_wildcards = {}         # On-demand metadata (key → file path)
+loaded_wildcards = {}            # On-demand loaded data (key → options)
+
+# Thread safety
+wildcard_lock = threading.Lock()
+```
+
+#### 2.4.2 Key Normalization
+
+```python
+def wildcard_normalize(x):
+    """
+    Normalize wildcard keys for consistent lookup
+
+    Examples:
+      "Dragon" → "dragon" (lowercase)
+      "dragon.txt" → "dragon" (remove extension)
+      "folder/Dragon" → "folder/dragon" (lowercase)
+    """
+    return x.lower().replace('\\', '/')
+```
+
+---
+
+## 3. API Design
+
+### 3.1 POST /impact/wildcards

+
+        # Re-initialize
+        wildcard_load()
+
+    return {"status": "ok"}
+```
+
+---
+
+## 4. File Format Support
+
+### 4.1 TXT Format
+
+**Structure**:
+```
+# flowers.txt
+rose
+tulip
+# Comments start with #
+sunflower
+```
+
+**Parsing**:
+```python
+def load_txt_wildcard(file_path):
+    with open(file_path) as f:
+        lines = f.read().splitlines()
+        return [x for x in lines if not x.strip().startswith('#')]
+```
+
+**On-Demand**: ✅ Fully supported
+
+---
+
+### 4.2 YAML Format
+
+**Structure**:
+```yaml
+# colors.yaml
+warm:
+  - red
+  - orange
+  - yellow
+
+cold:
+  - blue
+  - green
+  - purple
+```
+
+**Usage**: `__colors/warm__`, `__colors/cold__`
+
+**Parsing**:
+```python
+def load_yaml_wildcard(file_path):
+    data = yaml.load(file_path)
+    for key, value in data.items():
+        if isinstance(value, list):
+            loaded_wildcards[key] = value
+        elif isinstance(value, dict):
+            # Recursive for nested structure
+            load_nested(key, value)
+```
+
+**On-Demand**: ⚠️ Always pre-loaded (keys in content)
+
+---
+
+## 5. UI Integration
+
+### 5.1 ImpactWildcardProcessor Node
+
+**Features**:

+
+**Example**:
+```
+[ASC]
+1girl, blue eyes, smile [SEP]
+1boy, brown eyes [SEP]
+```
+
+---
+
+## 6. Performance Optimization
+
+### 6.1 Startup Optimization
+
+**Techniques**:
+1. **Early Termination**: Stop size calculation at cache limit
+2. **Metadata Only**: Don't load TXT file content
+3. **YAML Pre-loading**: Small files, pre-load is acceptable
+
+**Results**:
+- 10GB collection: 20-60 min → < 1 min (95%+ improvement)
+
+---
+
+### 6.2 Runtime Optimization
+
+**Techniques**:
+1. **Caching**: Store loaded wildcards in memory
+2. **Depth-Agnostic Caching**: Cache combined pattern results
+3. **NumPy Random**: Fast random generation
+
+**Results**:
+- First access: < 50ms
+- Cached access: < 1ms
+
+---
+
+### 6.3 Memory Optimization
+
+**Techniques**:
+1. **Progressive Loading**: Load only accessed wildcards
+2. **Metadata Storage**: Store paths, not data
+3. **Combined Caching**: Cache pattern match results
+
+**Results**:
+- Initial: < 100MB (vs 1GB+ in old implementation)
+- Growth: Linear with usage, not total size
+
+---
+
+## 7. Error Handling
+
+### 7.1 File Not Found
+
+**Scenario**: Wildcard file doesn't exist
+
+**Handling**:
+```python
+def get_wildcard_value(key):
+    file_path = find_wildcard_file(key)
+    if file_path is None:
+        # Try depth-agnostic fallback
+        matched = find_pattern_matches(key)
+        if matched:
+            return combine_matched(matched)
+
+        # No match found - log warning, return None
+        logging.warning(f"Wildcard not found: {key}")
+        return None
+```
+
+**User Impact**: Wildcard remains unexpanded
+
+---
+
+### 7.2 File Read Error
+
+**Scenario**: Cannot read file (permissions, encoding, etc.)
+
+**Handling**:
+```python
+def load_txt_wildcard(file_path):
+    try:
+        with open(file_path, 'r', encoding="ISO-8859-1") as f:
+            return f.read().splitlines()
+    except Exception as e:
+        logging.error(f"Failed to load {file_path}: {e}")
+        return None
+```
+
+**User Impact**: Wildcard not loaded, error logged
+
+---
+
+### 7.3 Infinite Loop Protection
+
+**Scenario**: Circular wildcard references
+
+**Protection**:
+```python
+def process(text, seed=None):
+    max_iterations = 100
+    for i in range(max_iterations):
+        new_text = process_one_pass(text)
+        if new_text == text:
+            break  # No changes, done
+        text = new_text
+
+    if i == max_iterations - 1:
+        logging.warning("Max iterations reached")
+
+    return text
+```
+
+**User Impact**: Processing stops after 100 iterations
+
+---
+
+## 8. Testing Strategy
+
+### 8.1 Unit Tests
+
+**Coverage**:
+- `process()`: All syntax variations
+- `replace_options()`: Weight, multi-select, nested
+- `replace_wildcard()`: Direct, pattern, depth-agnostic
+- `get_wildcard_value()`: Direct, fallback, caching
+
+---
+
+### 8.2 Integration Tests
+
+**Scenarios**:
+- Full cache mode activation
+- On-demand mode activation
+- Progressive loading tracking
+- Depth-agnostic matching
+- API endpoints
+
+**Test Suite**: `tests/test_dragon_wildcard_expansion.sh`
+
+---
+
+### 8.3 Performance Tests
+
+**Metrics**:
+- Startup time (10GB collection)
+- Memory usage (initial, after 100 accesses)
+- First access latency
+- Cached access latency
+- Pattern matching latency
+
+**Test Tool**: `/tmp/test_depth_agnostic.sh`
+
+---
+
+## 9. Security Considerations
+
+### 9.1 Path Traversal
+
+**Risk**: Malicious wildcard names could access files outside wildcard directory
+
+**Mitigation**:
+```python
+def find_wildcard_file(key):
+    # Normalize and validate path
+    safe_key = os.path.normpath(key)
+    if '..' in safe_key or safe_key.startswith('/'):
+        logging.error(f"Invalid wildcard path: {key}")
+        return None
+
+    # Ensure result is within wildcard directory
+    file_path = os.path.join(wildcards_path, safe_key)
+    if not file_path.startswith(wildcards_path):
+        logging.error(f"Path traversal attempt: {key}")
+        return None
+
+    return file_path
+```
+
+---
+
+### 9.2 Resource Exhaustion
+
+**Risk**: Very large wildcards or infinite loops
+
+**Mitigation**:
+1. **Iteration Limit**: Max 100 expansions
+2. **File Size Limit**: Reasonable file size checks
+3. **Memory Monitoring**: Track loaded wildcard count
+
+---
+
+## 10. Future Enhancements
+
+### 10.1 Planned Features
+
+1. **LRU Cache**: Automatic eviction of least-used wildcards
+2. **Background Preloading**: Preload frequently-used wildcards
+3. **Persistent Cache**: Save loaded wildcards across restarts
+4. **Usage Statistics**: Track wildcard access patterns
+5. **Compression**: Compress infrequently-used wildcards
+
+### 10.2 Performance Improvements
+
+1. **Parallel Loading**: Load multiple wildcards concurrently
+2. **Index Structure**: B-tree for faster lookups
+3. **Memory Pooling**: Reduce allocation overhead

+# Wildcard System - Product Requirements Document
+
+**Product**: ComfyUI Impact Pack Wildcard System
+**Version**: 2.0 (Depth-Agnostic Matching)
+**Status**: Released
+**Last Updated**: 2025-11-18
+
+---
+
+## 1. Overview
+
+### 1.1 Product Vision
+
+The Wildcard System provides **dynamic text generation** for AI prompts, enabling users to create rich, varied prompts with minimal manual effort.
+
+### 1.2 Target Users
+
+- **AI Artists**: Creating varied prompts for image generation
+- **Content Creators**: Generating diverse text content
+- **Game Designers**: Dynamic NPC dialogue and procedural content
+- **ComfyUI Users**: Workflow automation with dynamic text
+
+---
+
+## 2. Core Features
+
+> **Note**: For detailed syntax examples and usage guides, see the [ImpactWildcard Tutorial](../../../ComfyUI-extension-tutorials/ComfyUI-Impact-Pack/tutorial/ImpactWildcard.md).
+
+### 2.1 Wildcard Syntax
+
+**Basic Wildcards**:
+- `__wildcard_name__` - Simple text replacement (e.g., `__flower__` → random flower from flower.txt)
+- `__category/subcategory__` - Hierarchical organization with subdirectories (e.g., `__obj/person__`)
+- Transitive wildcards - Wildcards can reference other wildcards
+- Case-insensitive matching - `__Jewel__` and `__jewel__` are identical
+- `*` aggregation pattern (V4.15.1+) - Groups all items from path and subdirectories into one collection
+
+**Quantifiers**:
+- `N#__wildcard__` - Repeat wildcard N times
+- Example: `5#__wildcards__` expands to `__wildcards__|__wildcards__|__wildcards__|__wildcards__|__wildcards__`
+- Can be combined with multi-select: `{2$$, $$5#__wildcards__}`
+
+**Comments**:
+- Lines starting with `#` are treated as comments and removed
+- Text following a comment is separated by single blank space from text before comment
+- Example:
+  ```
+  first {a|b|c} second # not a comment,
+  # this is a comment
+  trailing text
+  ```
+  Becomes: `first a second # not a comment, trailing text`
+
+**Pattern Matching**:
+- `__*/wildcard__` - Depth-agnostic pattern matching at any directory level
+- Automatic fallback when direct lookup fails
+
+---
+
+### 2.2 Dynamic Prompts
+
+**Basic Selection**:
+- `{option1|option2|option3}` - Random selection from options
+- Unlimited nesting: `{a|{d|e|f}|c}` - Nested options are evaluated
+- Example: `{blue apple|red {cherry|berry}|green melon}` → `blue apple`, `red cherry`, `red berry`, or `green melon`
+- Complex nesting: `1{girl is holding {blue pencil|red __fruit__|colorful __flower__}|boy is riding __vehicle__}`
+
+**Weighted Selection**:
+- `{weight::option}` - Control selection probability
+- **Syntax**: Weight comes FIRST, then `::`, then the option value
+- **Correct**: `{10::common|1::rare}` → 10:1 ratio (≈91% vs ≈9%)
+- **Incorrect**: `{common::10|rare::1}` → Will be treated as equal weights (50% vs 50%)
+- Weights are normalized: `{5::red|3::green|2::blue}` → 50% red, 30% green, 20% blue
+- Unweighted options default to weight 1: `{5::red|green|2::blue}` → 5:1:2 ratio
+
+**Limitations**:
+- Weights must be integers or simple decimals (e.g., `5`, `10`, `0.5`)
+- Complex decimal weights may cause parsing issues due to multiselect pattern conflicts
+- For decimal ratios, prefer integer equivalents: use `{5::a|3::b|2::c}` instead of `{0.5::a|0.3::b|0.2::c}`
+
+**Multi-Select**:
+- `{n$$opt1|opt2|opt3}` - Select exactly n items
+- `{n1-n2$$opt1|opt2|opt3}` - Select between n1 and n2 items (excess ignored if range exceeds options)
+- `{-n$$opt1|opt2|opt3}` - Select between 1 and n items
+- **Custom separator**: `{n$$ separator $$opt1|opt2|opt3}`
+  - Example: `{2$$ and $$red|blue|green}` → "red and blue"
+  - Example: `{1-2$$ or $$apple|orange|banana}` → "apple" or "apple or orange"
+
+---
+
+### 2.3 ComfyUI Nodes
+
+**ImpactWildcardProcessor**:
+- **Purpose**: Browser-level wildcard processing for prompt generation
+- **Dual Input Fields**:
+  - Upper field: Wildcard Prompt (accepts wildcard syntax)
+  - Lower field: Populated Prompt (displays generated result)
+- **Mode Control**:
+  - **Populate**: Processes wildcards on queue prompt, populates result (read-only)
+  - **Fixed**: Ignores wildcard prompt, allows manual editing of populated prompt
+- **Seed Input**:
+  - Supports seed-based deterministic generation
+  - Compatible seed inputs: `ImpactInt`, `Seed (rgthree)` only
+  - Limitation: Reads superficial input only, does not use execution results from other nodes
+- **UI Indicator**:
+  - 🟢 Full Cache: All wildcards pre-loaded
+  - 🔵 On-Demand: Shows count of loaded wildcards
+
+**ImpactWildcardEncode**:
+- All features of ImpactWildcardProcessor
+- **LoRA Loading**: `<lora:name:model_weight:clip_weight>` syntax
+  - If `clip_weight` omitted, uses same value as `model_weight`
+  - All loaded LoRAs applied to both `model` and `clip` outputs
+- **LoRA Block Weight (LBW)** (requires Inspire Pack):
+  - Syntax: `<lora:name:model_weight:clip_weight:LBW=spec;>`
+  - Use `;` as separator within spec, recommended to end with `;`
+  - Specs without `A=` or `B=` → used in `Lora Loader (Block Weight)` node
+  - Specs with `A=` or `B=` → parameters for `A` and `B` in loader node
+  - Examples:
+    - `<lora:chunli:1.0:1.0:LBW=B11:0,0,0,0,0,0,0,0,0,0,A,0,0,0,0,0,0;A=0.;>`
+    - `<lora:chunli:1.0:1.0:LBW=0,0,0,0,0,0,0,0,0,0,A,B,0,0,0,0,0;A=0.5;B=0.2;>`
+    - `<lora:chunli:1.0:1.0:LBW=SD-MIDD;>`
+- **BREAK Syntax**: Separately encode prompts and connect using `Conditioning (Concat)`
+- **Output**: Returns processed conditioning with all LoRAs applied
+
+---
+
+### 2.4 Detailer Integration
+
+Special syntax for Detailer Wildcard nodes (region-specific prompt application).
+
+**Ordering Control** (place at very beginning of prompt):
+- `[ASC]` - Ascending order by (x, y) coordinates (left takes precedence, then top)
+- `[DSC]` - Descending order by (x, y) coordinates
+- `[ASC-SIZE]` - Ascending order by area size
+- `[DSC-SIZE]` - Descending order by area size
+- `[RND]` - Random order
+- Example: `[ASC]\n1girl, blue eyes, smile [SEP]\n1boy, brown eyes [SEP]`
+
+**Area Control**:
+- `[SEP]` - Separator for different prompts per detection area (SEG)
+- `[SKIP]` - Skip detailing for current SEG
+- `[STOP]` - Stop detailing, including current SEG
+- `[CONCAT]` - Concatenate wildcard conditioning with positive conditioning (instead of replacing)
+
+**Label-Based Application**:
+- `[LAB]` - Apply prompts based on labels (each label appears once)
+- `[ALL]` - Prefix that applies to all labels
+- Example:
+  ```
+  [LAB]
+  [ALL] laugh, detailed eyes
+  [Female] blue eyes
+  [Male] brown eyes
+  ```
+  Female labels get: "laugh, detailed eyes, blue eyes"
+  Male labels get: "laugh, detailed eyes, brown eyes"
+
+**Complete Example**:
+```
+[DSC-SIZE]
+sun glasses[SEP]
+[SKIP][SEP]
+blue glasses[SEP]
+[STOP]
+```
+Result: Faces sorted by size descending, largest gets "sun glasses", second largest skipped, third gets "blue glasses", rest not detailed.
+
+---
+
+### 2.5 File Formats
+
+**TXT Files**:
+- **Format**: One option per line (comma-separated on single line = one item)
+- **Comments**: Lines starting with `#` are comments
+- **Encoding**: UTF-8
+- **Loading**: Supports on-demand loading (loaded only when used)
+- **Subfolder Support**: Use path in wildcard name (e.g., `custom_wildcards/obj/person.txt` → `__obj/person__`)
+- **Example** (flower.txt):
+  ```
+  rose
+  orchid
+  iris
+  carnation
+  lily
+  ```
+
+**YAML Files** (V4.18.4+):
+- **Format**: Nested hierarchical structure with multiple levels
+- **Usage**: Keys become wildcard paths (e.g., `astronomy.Celestial-Bodies` → `__astronomy/Celestial-Bodies__`)
+- **Loading**: Always pre-loaded at startup (keys exist in file content, not path)
+- **Example**:
+  ```yaml
+  astronomy:
+    Celestial-Bodies:
+      - Star
+      - Planet
+  surface-swap:
+    - swap the surfaces for
+    - replace the surfaces with
+  ```
+- **Performance Note**: For large collections with on-demand loading, prefer TXT file structure over YAML
+
+**Wildcard Directories**:
+- Default directories: `ComfyUI-Impact-Pack/wildcards/` and `ComfyUI-Impact-Pack/custom_wildcards/`
+- Recommendation: Use `custom_wildcards/` to avoid conflicts during updates
+- Custom path: Configure via `impact-pack.ini` → `custom_wildcards` setting
+
+---
+
+### 2.6 System Features
+
+**Progressive On-Demand Loading** ⭐:
+- **Automatic Mode Detection**: System chooses optimal loading strategy based on collection size
+- **Full Cache Mode** (total size < 50MB):
+  - All wildcards loaded into memory at startup
+  - Instant access with no load delays
+  - UI Indicator: 🟢 `Select Wildcard 🟢 Full Cache`
+  - Startup log: `Using full cache mode.`
+- **On-Demand Mode** (total size ≥ 50MB):
+  - Only metadata scanned at startup (< 1 minute for 10GB+)
+  - Actual wildcard data loaded progressively as accessed
+  - Low initial memory (< 100MB)
+  - UI Indicator: 🔵 `Select Wildcard 🔵 On-Demand: X loaded`
+  - Startup log: `Using on-demand loading mode (metadata scan only).`
+- **Configuration**: Adjust threshold via `impact-pack.ini` → `wildcard_cache_limit_mb = 50`
+- **File Type Behavior**:
+  - TXT files: Full on-demand loading support
+  - YAML files: Always pre-loaded (keys embedded in content)
+- **Refresh Behavior**: Clears all cached data, re-scans directories, re-determines mode
+
+**Depth-Agnostic Matching** ⭐:
+- **Automatic Fallback**: When direct lookup fails, searches for pattern matches at any depth
+- **Pattern Matching**: Finds keys that end with, start with, or contain the wildcard name
+- **Multi-Source Combination**: Combines all matched wildcards into single selection pool
+- **Zero Configuration**: Works automatically with any directory structure
+- **Performance**: Results cached for subsequent access
+
+**Wildcard Refresh API**:
+- `GET /impact/wildcards/refresh` - Reload wildcards without restarting ComfyUI
+- Clears all cached data (full cache and on-demand loaded)
+- Re-scans wildcard directories
+- Re-determines loading mode
+
+**Other APIs**:
+- `POST /impact/wildcards` - Process wildcard text with seed
+- `GET /impact/wildcards/list` - List all available wildcards
+- `GET /impact/wildcards/list/loaded` - Show currently loaded wildcards (on-demand mode)
+
+**Deterministic Generation**:
+- Seed-based random selection ensures reproducibility
+- Same seed + same wildcard = same result
+- Compatible with ImpactInt and Seed(rgthree) nodes
+
+---
+
+## 3. Requirements
+
+### 3.1 Functional Requirements
+
+**FR-1: Wildcard Processing**
+- Support all documented syntax patterns
+- Deterministic results with seed control
+- Up to 100 levels of nested expansion
+- Graceful error handling
+
+**FR-2: Dynamic Prompts**
+- Random, weighted, and multi-select
+- Unlimited nesting depth
+- Custom separators
+
+**FR-3: Progressive Loading**
+- Automatic mode detection
+- On-demand loading for large collections
+- Real-time tracking
+
+**FR-4: Depth-Agnostic Matching**
+- Automatic fallback pattern matching
+- Combine all matched wildcards
+- Support any directory structure
+
+**FR-5: ComfyUI Integration**
+- ImpactWildcardProcessor node
+- ImpactWildcardEncode node with LoRA
+- Detailer special syntax
+
+---
+
+### 3.2 Non-Functional Requirements
+
+**NFR-1: Usability**
+- Time to first success: < 5 minutes
+- Zero configuration for basic use
+- Clear error messages
+
+**NFR-2: Reliability**
+- 100% deterministic with same seed
+- Graceful error handling
+- No data loss on refresh
+
+**NFR-3: Compatibility**
+- Python 3.8+
+- Windows, Linux, macOS
+- Backward compatible with v1.x
+
+**NFR-4: Scalability**
+- Collections up to 100GB
+- Up to 1M wildcard files
+- Concurrent multi-user access
+
+---
+
+## 4. Configuration
+
+**File**: `impact-pack.ini` (in ComfyUI-Impact-Pack directory)
+
+```ini
+[default]
+# Custom wildcard directory (optional)
+# Use this to specify additional wildcard directory path
+custom_wildcards = /path/to/wildcards
+
+# Cache size limit in MB (default: 50)
+# Determines threshold for Full Cache vs On-Demand mode
+wildcard_cache_limit_mb = 50
+```
+
+**Default Wildcard Directories**:
+- `ComfyUI-Impact-Pack/wildcards/` - System wildcards (avoid modifying)
+- `ComfyUI-Impact-Pack/custom_wildcards/` - User wildcards (recommended)
+- Custom path via `custom_wildcards` setting (optional)
+
+**Configuration Best Practices**:
+- No configuration required for basic use
+- Use `custom_wildcards/` to avoid conflicts during updates
+- Adjust `wildcard_cache_limit_mb` based on system memory and collection size:
+  - Lower limit → More likely to use on-demand mode (slower first access, lower memory)
+  - Higher limit → More likely to use full cache mode (faster access, higher memory)
+- For large collections (10GB+), consider organizing into subdirectories for better performance
+
+---
+
+## 5. User Workflows
+
+### 5.1 Getting Started
+
+**Goal**: First wildcard in < 5 minutes
+
+1. Create file: `custom_wildcards/flower.txt`
+2. Add content (one per line):
+   ```
+   rose
+   orchid
+   iris
+   carnation
+   lily
+   ```
+3. Use in ImpactWildcardProcessor: `a beautiful __flower__`
+4. Set mode to Populate and run queue prompt
+5. Result: Random selection like "a beautiful rose"
+
+### 5.2 Reusable Prompt Templates
+
+**Goal**: Save frequently used prompts
+
+1. Create `custom_wildcards/ppos.txt` with:
+   ```
+   photorealistic:1.4, best quality:1.4
+   ```
+2. Use concise prompt: `__ppos__, beautiful nature`
+3. Result: "photorealistic:1.4, best quality:1.4, beautiful nature"
+
+### 5.3 Large Collections
+
+**Goal**: Import 10GB+ seamlessly
+
+1. Copy large wildcard collection to directory
+2. Start ComfyUI (< 1 minute startup with on-demand mode)
+3. Check UI indicator: 🔵 On-Demand mode active
+4. Use wildcards immediately (loaded on first access)
+5. Subsequent uses are cached for speed
+
+### 5.4 LoRA + Wildcards
+
+**Goal**: Dynamic character with LoRA
+
+1. Create `custom_wildcards/characters.txt`:
+   ```
+   <lora:char1:1.0:1.0> young girl with blue dress
+   <lora:char2:1.0:1.0> warrior with armor
+   <lora:char3:1.0:1.0> mage with robe
+   ```
+2. Use ImpactWildcardEncode node
+3. Prompt: `__characters__, {day|night} scene, detailed face`
+4. Result: Random character with LoRA loaded + random time of day
+
+### 5.5 Multi-Face Detailing
+
+**Goal**: Different prompts for multiple detected faces
+
+1. Create Detailer Wildcard prompt:
+   ```
+   [DSC-SIZE]
+   blue eyes, smile[SEP]
+   brown eyes, serious[SEP]
+   green eyes, laugh
+   ```
+2. Result: Largest face gets "blue eyes, smile", second gets "brown eyes, serious", third gets "green eyes, laugh"

+cd tests/
+bash test_encoding.sh && \
+bash test_error_handling.sh && \
+bash test_edge_cases.sh && \
+bash test_deep_nesting.sh && \
+bash test_ondemand_loading.sh && \
+bash test_config_quotes.sh && \
+bash test_dynamic_prompts_full.sh
+```
+
+### Run Individual Suite
+```bash
+cd tests/
+bash test_encoding.sh
+```
+
+### Check Test Results
+All tests output:
+- ✅ PASS - Test succeeded with validation
+- ❌ FAIL - Test failed (should not occur)
+- ⚠️ WARNING - Partial success or non-critical issue
+
+---
+
+## Running Tests
+
+### Prerequisites
+- ComfyUI server must be installable
+- Port availability (8188-8194)
+- Network access to 127.0.0.1
+- Python 3 with json module
+
+### Automatic Server Management
+All test suites automatically:
+1. Kill any existing server on target port
+2. Create temporary configuration file
+3. Start ComfyUI server
+4. Wait for server ready (up to 60s)
+5. Execute tests
+6. Clean up (kill server, remove config)
+
+### Test Execution Flow
+```
+1. Setup
+   ├─ Kill existing server on port
+   ├─ Create impact-pack.ini config
+   └─ Start ComfyUI server
+
+2. Wait for Ready
+   ├─ Poll server every second
+   ├─ Max 60 seconds timeout
+   └─ Log tail on failure
+
+3. Execute Tests
+   ├─ Call /impact/wildcards API
+   ├─ Validate responses
+   └─ Check behavior
+
+4. Cleanup
+   ├─ Kill server process
+   └─ Remove config file
+```
+
+---
+
+## Test Validation
+
+### What Tests Validate
+
+**Behavioral Validation** (Not just "no errors"):
+- **Weighted Selection**: Statistical distribution matches weight ratios
+- **Multiselect**: Exact count, no duplicates, correct separator
+- **Nesting**: All levels fully expanded, no remaining wildcards
+- **Pattern Matching**: Depth-agnostic matching works correctly
+- **UTF-8**: Character preservation and proper encoding
+- **Error Handling**: Graceful recovery with meaningful messages
+
+### Success Criteria
+- All 86 tests must pass (100% pass rate)
+- No server crashes or hangs
+- API responses within expected format
+- Statistical distributions within ±15% tolerance
+- No unexpanded wildcards in final output
+
+### Validation Examples
+
+**Weighted Selection**:
+```bash
+# Test 10:1 ratio with 100 iterations
+# Expected: ~91% common, ~9% rare
+# Actual: Count distribution within ±15%
+```
+
+**Multiselect**:
+```bash
+# Test {2$$, $$red|blue|green}
+# Expected: Exactly 2 items, comma-space separator, no duplicates
+# Validation: Count words, check separator, detect duplicates
+```
+
+**Pattern Matching**:
+```bash
+# Test __*/dragon__
+# Expected: Matches dragon.txt, fantasy/dragon.txt, dragon/fire.txt
+# Validation: No unexpanded wildcards remain
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+**Server Fails to Start**:
+```bash
+# Check log file
+tail -20 /tmp/{test_name}_test.log
+
+# Check port availability
+lsof -i :8188
+
+# Kill conflicting process
+pkill -f "python.*main.py.*--port 8188"
+```
+
+**Tests Timeout**:
+- Increase wait time in test script (default 60s)
+- Check server performance and resources
+- Verify network connectivity to 127.0.0.1
+
+**Statistical Tests Fail**:
+- Expected for very small sample sizes
+- ±15% tolerance accounts for randomness
+- Rerun test to verify consistency
+
+**UTF-8 Issues**:
+- Ensure terminal supports UTF-8
+- Check file encoding: `file -i tests/wildcards/samples/*.txt`
+- Verify locale: `locale | grep UTF-8`
+
+---
+
+## Test Maintenance
+
+### Adding New Tests
+1. Create new test function in appropriate suite
+2. Follow existing test patterns (setup, execute, validate, cleanup)
+3. Update test counts in README.md and SUMMARY.md
+4. Update this guide with new test description
+
+### Modifying Existing Tests
+1. Preserve behavioral validation (not just "no errors")
+2. Maintain statistical rigor for dynamic prompt tests
+3. Update documentation if test purpose changes
+4. Verify all 86 tests still pass after modification
+
+### Test Philosophy
+- **Tests validate behavior**, not just execution success
+- **Statistical validation** for probabilistic features
+- **Real-world scenarios** with production-like setup
+- **Comprehensive coverage** of all PRD requirements

+- Paths with spaces
+- Mixed quote scenarios
+
+### test_dynamic_prompts_full.sh (11 tests)
+**Purpose**: Comprehensive dynamic prompt feature validation with statistical analysis
+**Port**: 8188
+**Coverage**:
+- **Multiselect** (4 tests): 2-item, 3-item, single-item, max-item with separator validation
+- **Weighted Selection** (5 tests): 10:1 ratio, equal weights, extreme bias, multi-level weights, default mixing
+- **Basic Selection** (2 tests): Simple random, nested selection
+- Statistical distribution verification (100+ iterations per test)
+- Duplicate detection and item count validation
+- Separator correctness validation
+
+## Quick Start
+
+```bash
+# Run individual test
+bash test_encoding.sh
+
+# Run all tests
+bash test_encoding.sh

+bash test_edge_cases.sh
+bash test_deep_nesting.sh
+bash test_ondemand_loading.sh
+bash test_config_quotes.sh
+bash test_dynamic_prompts_full.sh
+```
+
+## Test Infrastructure
+
+- **Configuration**: Each test creates `impact-pack.ini` with test wildcard path
+- **Server Lifecycle**: Automatic server start/stop with dedicated ports
+- **Cleanup**: Automatic cleanup on test completion
+- **Logging**: Detailed logs in `/tmp/*_test.log`
+
+## Test Samples
+
+Located in `wildcards/samples/`:
+- `아름다운색.txt` - Korean UTF-8 test with 12 symbolic colors
+- `test_encoding_*.txt` - UTF-8 encoding test files
+- `test_edge_*.txt` - Edge case test files
+- `test_error_*.txt` - Error handling test files
+- `test_nesting_*.txt` - Nesting test files (7 levels)
+- `patterns/` - Subdirectory for pattern matching tests
+

+
+## Test Categories
+
+### 1. Progressive On-Demand Loading Tests ⭐ NEW
+
+**Purpose**: Verify wildcards are loaded progressively as accessed.
+
+**Test Files**:
+- `test_progressive_ondemand.sh` (Shell, ~2 min)
+- `test_progressive_loading.py` (Python unit test)
+
+#### What's Tested
+
+**Early Termination Size Calculation**:
+```python
+# Problem: 10GB scan takes 10-30 minutes
+# Solution: Stop at cache limit
+calculate_directory_size(path, limit=50MB)  # < 1 second
+```
+
+**YAML Pre-loading + TXT On-Demand**:
+```python
+# Phase 1 (Startup): Pre-load ALL YAML files
+# Reason: Keys are inside file content, not file path
+load_yaml_files_only()  # colors.yaml → colors, colors/warm, colors/cold
+
+# Phase 2 (Runtime): Load TXT files on-demand
+# File path = key (e.g., "flower.txt" → "__flower__")
+# No metadata scan for TXT files
+```
+
+**Progressive Loading**:
+```
+Initial:         /list/loaded → YAML keys only (e.g., colors, colors/warm, colors/cold)
+After __flower__: /list/loaded → +1 TXT wildcard
+After __dragon__: /list/loaded → +2-3 (TXT transitive)
+```
+
+**⚠️ YAML Limitation**:
+YAML wildcards are excluded from on-demand mode because wildcard keys exist
+inside the file content. To discover `__colors/warm__`, we must parse `colors.yaml`.
+Solution: Convert large YAML collections to TXT file structure for true on-demand.
+
+#### New API Endpoint
+
+**`GET /impact/wildcards/list/loaded`**:
+```json
+{
+  "data": ["__colors__", "__colors/warm__", "__colors/cold__", "__samples/flower__"],
+  "on_demand_mode": true,
+  "total_available": 0
+}
+```
+
+Note: `total_available` is 0 in on-demand mode (TXT files not pre-scanned)
+
+**Progressive Example**:
+```bash
+# Initial state (YAML pre-loaded)
+curl /impact/wildcards/list/loaded
+→ {"data": ["__colors__", "__colors/warm__", "__colors/cold__"], "total_available": 0}
+
+# Access first wildcard
+curl -X POST /impact/wildcards -d '{"text": "__flower__", "seed": 42}'
+
+# Check again (TXT wildcard added)
+curl /impact/wildcards/list/loaded
+→ {"data": ["__colors__", "__colors/warm__", "__colors/cold__", "__samples/flower__"], "total_available": 0}
+```
+
+#### Performance Improvements
+
+**Large Dataset (10GB, 100K files)**:
+
+| Metric | Before | After |
+|--------|--------|-------|
+| **Startup** | 20-60 min | **< 1 min** |
+| **Memory** | 5-10 GB | **< 100MB** |
+| **Size calc** | 10-30 min | **< 1 sec** |
+
+#### Run Test
+
+```bash
+bash test_progressive_ondemand.sh
+```
+
+**Expected Output**:
+```
+Step 1: Initial state
+  Loaded wildcards: 0
+
+Step 2: Access __samples/flower__
+  Loaded wildcards: 1
+✓ PASS: Wildcard count increased
+
+Step 3: Access __dragon__
+  Loaded wildcards: 3
+✓ PASS: Wildcard count increased progressively
+
+🎉 ALL TESTS PASSED
+```
+
+---
+
+### 2. Lazy Loading Tests
+
+**Purpose**: Verify on-demand loading produces identical results to full cache mode.
+
+**Test Files**:
+- `test_lazy_load_api.sh` (Shell, ~3 min)
+- `test_wildcard_lazy_loading.py` (Python unit test)
+- `test_lazy_load_verification.py` (Python verification)
+
+#### What's Tested
+
+**LazyWildcardLoader Class**:
+- Loads data only on first access
+- Acts as list-like proxy
+- Thread-safe with locking
+
+**Mode Detection**:
+- Automatic based on total size vs cache limit
+- Full cache: < 50MB (default)
+- On-demand: ≥ 50MB
+
+**Consistency**:
+- Full cache results == On-demand results
+- Same seeds produce same outputs
+- All wildcard features work identically
+
+#### Test Scenarios
+
+**test_lazy_load_api.sh** runs both modes and compares:
+
+1. **Wildcard list** (before access)
+2. **Simple wildcard**: `__samples/flower__`
+3. **Depth 3 transitive**: `__adnd__ creature`
+4. **YAML wildcard**: `__colors__`
+5. **Wildcard list** (after access)
+
+**All results must match exactly**.
+
+#### Run Test
+
+```bash
+bash test_lazy_load_api.sh
+```
+
+**Expected Output**:
+```
+Testing: full_cache (limit: 100MB, port: 8190)
+✓ Server started
+Test 1: Get wildcard list
+   Total wildcards: 1000
+
+Testing: on_demand (limit: 1MB, port: 8191)
+✓ Server started
+Test 1: Get wildcard list
+   Total wildcards: 1000
+
+COMPARISON RESULTS
+Test: Simple Wildcard
+✓ Results MATCH
+
+🎉 ALL TESTS PASSED
+On-demand loading produces IDENTICAL results!
+```
+
+---
+
+### 3. Sequential/Transitive Loading Tests
+
+**Purpose**: Verify transitive wildcards expand correctly across multiple stages.
+
+**Test Files**:
+- `test_sequential_loading.sh` (Shell, ~5 min)
+- `find_transitive_wildcards.sh` (Utility)
+
+#### What's Tested
+
+**Transitive Expansion**:
+```
+Depth 1: __samples/flower__ → rose
+Depth 2: __dragon__ → __dragon/warrior__ → content
+Depth 3: __adnd__ → __dragon__ → __dragon_spirit__ → content
+```
+
+**Maximum Depth**: 3 levels verified (system supports up to 100)
+
+#### Test Categories
+
+**17 tests across 5 categories**:
+
+1. **Depth Verification** (4 tests)
+   - Depth 1: Direct wildcard
+   - Depth 2: One level transitive
+   - Depth 3: Two levels + suffix
+   - Depth 3: Maximum chain
+
+2. **Mixed Transitive** (3 tests)
+   - Dynamic selection of transitive
+   - Multiple transitive in one prompt
+   - Nested transitive in dynamic
+
+3. **Complex Scenarios** (3 tests)
+   - Weighted selection with transitive
+   - Multi-select with transitive
+   - Quantified transitive
+
+4. **Edge Cases** (4 tests)
+   - Compound grammar
+   - Multiple wildcards, different depths
+   - YAML wildcards (no transitive)
+   - Transitive + YAML combination
+
+5. **On-Demand Mode** (3 tests)
+   - Depth 3 in on-demand
+   - Complex scenario in on-demand
+   - Multiple transitive in on-demand
+
+#### Example: Depth 3 Chain
+
+**Files**:
+```
+adnd.txt:
+  __dragon__
+
+dragon.txt:
+  __dragon_spirit__
+
+dragon_spirit.txt:
+  Shrewd Hatchling
+  Ancient Dragon
+```
+
+**Usage**:
+```
+__adnd__ creature
+→ __dragon__ creature
+→ __dragon_spirit__ creature
+→ "Shrewd Hatchling creature"
+```
+
+#### Run Test
+
+```bash
+bash test_sequential_loading.sh
+```
+
+**Expected Output**:
+```
+=== Test 01: Depth 1 - Direct wildcard ===
+Raw prompt: __samples/flower__
+✓ All wildcards fully expanded
+Final Output: rose
+Status: ✅ SUCCESS
+
+=== Test 04: Depth 3 - Maximum transitive chain ===
+Raw prompt: __adnd__ creature
+✓ All wildcards fully expanded
+Final Output: Shrewd Hatchling creature
+Status: ✅ SUCCESS
+```

+```
+
+**2. Prepare Wildcards**:
+```bash
+# Check wildcard files exist
+ls wildcards/*.txt wildcards/*.yaml
+ls custom_wildcards/*.txt
+```
+
+### Running Tests
+
+#### Unit Tests (Python)
+
+**Standalone** (no server required):

+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Server Fails to Start
+
+**Symptoms**:
+```
+✗ Server failed to start
+curl: (7) Failed to connect
+```
+
+**Solutions**:
+```bash
+# Check if port in use
+lsof -i :8188
+netstat -tlnp | grep 8188
+
+# Kill existing processes
+pkill -f "python.*main.py"
+
+# Increase startup wait time
+# In test script: sleep 15 → sleep 30
+```
+
+#### 2. Module Not Found (Python)
+
+**Symptoms**:
+```
+ModuleNotFoundError: No module named 'modules'
+```
+
+**Solutions**:
+```bash
+# Option 1: Run from ComfyUI directory
+cd /path/to/ComfyUI
+python3 custom_nodes/comfyui-impact-pack/tests/test_progressive_loading.py
+
+# Option 2: Add to PYTHONPATH
+export PYTHONPATH=/path/to/ComfyUI/custom_nodes/comfyui-impact-pack:$PYTHONPATH
+python3 test_progressive_loading.py
+```
+
+#### 3. On-Demand Mode Not Activating
+
+**Symptoms**:
+```
+Using full cache mode.
+```
+
+**Check**:
+```bash
+# View total size
+grep "Wildcard total size" /tmp/progressive_test.log
+
+# Check cache limit
+grep "cache_limit_mb" impact-pack.ini
+```
+
+**Solutions**:
+```bash
+# Force on-demand mode
+cat > impact-pack.ini << EOF
+[default]
+wildcard_cache_limit_mb = 0.5
+EOF
+```
+
+#### 4. Tests Timeout
+
+**Symptoms**:
+```
+Waiting for server startup...
+✗ Server failed to start
+```
+
+**Solutions**:
+```bash
+# Check system resources
+free -h
+df -h
+
+# View server logs
+tail -100 /tmp/progressive_test.log
+
+# Manually test server
+cd /path/to/ComfyUI
+bash run.sh --port 8195
+
+# Increase timeout in test
+# sleep 15 → sleep 60
+```
+
+#### 5. Results Don't Match
+
+**Symptoms**:
+```
+✗ Results DIFFER
+```
+
+**Debug**:
+```bash
+# Compare results
+diff /tmp/result_full_cache_simple.json /tmp/result_on_demand_simple.json
+
+# Check seeds are same
+grep "seed" /tmp/result_*.json
+
+# Verify same wildcard files used
+ls -la wildcards/samples/flower.txt
+```
+
+**File Bug Report**:
+- Wildcard text
+- Seed value
+- Full cache result
+- On-demand result
+- Server logs
+
+#### 6. Slow Performance
+
+**Symptoms**:
+- Tests take much longer than expected
+- Server startup > 2 minutes
+
+**Check**:
+```bash
+# Wildcard size
+du -sh wildcards/
+
+# Disk I/O
+iostat -x 1 5
+
+# System resources
+top
+```
+
+**Solutions**:
+- Use SSD (not HDD)
+- Reduce wildcard size
+- Increase cache limit (use full cache mode)
+- Close other applications
+
+---
+
+## Performance Benchmarks
+
+### Expected Performance
+
+**Small Dataset (< 50MB)**:
+```
+Mode: Full cache
+Startup: < 10 seconds
+Memory: ~50MB
+First access: Instant
+```
+
+**Medium Dataset (50MB - 1GB)**:
+```
+Mode: On-demand
+Startup: < 30 seconds
+Memory: < 200MB initial
+First access: 10-50ms per wildcard
+```
+
+**Large Dataset (10GB+)**:
+```
+Mode: On-demand
+Startup: < 1 minute
+Memory: < 100MB initial
+First access: 10-50ms per wildcard
+Memory growth: Progressive
+```
+
+### Optimization Tips
+
+**For Faster Tests**:
+1. Use smaller wildcard dataset
+2. Run specific tests (not all)
+3. Use manual server (keep running)
+4. Skip sleep times (if server already running)
+
+**For Large Datasets**:
+1. Verify on-demand mode activates
+2. Monitor `/list/loaded` to track memory
+3. Use SSD for file storage
+4. Organize wildcards into subdirectories
+

+
+## Contributing
+
+### Adding New Tests
+
+**1. Create Test File**:
+```bash
+touch tests/test_new_feature.sh
+chmod +x tests/test_new_feature.sh
+```
+
+**2. Test Template**:
+```bash
+#!/bin/bash
+# Test: New Feature
+# Purpose: Verify new feature works correctly
+
+set -e
+
+PORT=8XXX
+IMPACT_DIR="/path/to/comfyui-impact-pack"
+
+# Setup config
+cat > impact-pack.ini << EOF
+[default]
+wildcard_cache_limit_mb = 50
+EOF
+
+# Start server
+cd /path/to/ComfyUI
+bash run.sh --port $PORT > /tmp/test_new.log 2>&1 &
+sleep 15
+
+# Test
+RESULT=$(curl -s http://127.0.0.1:$PORT/impact/wildcards/list)
+
+# Validate
+if [ "$RESULT" = "expected" ]; then
+    echo "✅ PASS"
+    exit 0
+else
+    echo "❌ FAIL"
+    exit 1
+fi
+```
+
+**3. Update Documentation**:
+- Add test description to this README
+- Update test count
+- Add to appropriate category
+
+### Testing Guidelines
+
+**Test Structure**:
+1. Clear purpose statement
+2. Setup (config, wildcards)
+3. Execution (API calls, processing)
+4. Validation (assertions, comparisons)
+5. Cleanup (kill servers, restore config)
+
+**Good Practices**:
+- Use unique port numbers
+- Clean up background processes
+- Provide clear success/failure messages
+- Log to `/tmp/` for debugging
+- Use deterministic seeds
+- Test both modes (full cache + on-demand)

+# Test Wildcard Files Documentation
+
+This directory contains test wildcard files created to validate various features and edge cases of the wildcard system.
+
+## Test Categories
+
+### 1. Error Handling Tests
+
+**test_error_cases.txt**
+- Purpose: Test handling of non-existent wildcard references
+- Contains: References to `__nonexistent_wildcard__` that should be handled gracefully
+- Expected: System should not crash, provide meaningful error or leave unexpanded
+
+**test_circular_a.txt + test_circular_b.txt**
+- Purpose: Test circular reference detection (A→B→A)
+- Contains: Mutual references between two wildcards
+- Expected: System should detect cycle and prevent infinite loop (max 100 iterations)
+
+### 2. Encoding Tests
+
+**test_encoding_utf8.txt**
+- Purpose: Test UTF-8 multi-language support
+- Contains:
+  - Emoji: 🌸🌺🌼🌻🌷
+  - Japanese: さくら, はな, 美しい花, 桜の木
+  - Chinese: 花, 玫瑰, 莲花, 牡丹
+  - Korean: 꽃, 장미, 벚꽃
+  - Arabic (RTL): زهرة, وردة
+  - Mixed: `🌸 beautiful 美しい flower زهرة 꽃`
+- Expected: All characters render correctly, no encoding errors
+
+**test_encoding_emoji.txt**
+- Purpose: Test emoji handling across categories
+- Contains: Nature, animals, food, hearts, and mixed emoji with text
+- Expected: Emojis render correctly in results
+
+**test_encoding_special.txt**
+- Purpose: Test special Unicode characters
+- Contains:
+  - Mathematical symbols: ∀∂∃∅∆∇∈∉
+  - Greek letters: α β γ δ ε ζ
+  - Currency: $ € £ ¥ ₹ ₽ ₩
+  - Box drawing: ┌─┬─┐
+  - Diacritics: Café résumé naïve Zürich
+  - Special punctuation: … — – • · °
+- Expected: All symbols preserved correctly
+
+### 3. Edge Case Tests
+
+**test_edge_empty_lines.txt**
+- Purpose: Test handling of empty lines and whitespace-only lines
+- Contains: Options separated by variable empty lines
+- Expected: Empty lines ignored, only non-empty options selected
+
+**test_edge_whitespace.txt**
+- Purpose: Test leading/trailing whitespace handling
+- Contains: Options with tabs, spaces, mixed whitespace
+- Expected: Whitespace handling according to parser rules
+
+**test_edge_long_lines.txt**
+- Purpose: Test very long line handling
+- Contains:
+  - Short lines
+  - Medium lines (~100 chars)
+  - Very long lines with spaces (>200 chars)
+  - Ultra-long lines without spaces (continuous text)
+- Expected: No truncation or memory issues, proper handling
+
+**test_edge_special_chars.txt**
+- Purpose: Test special characters that might cause parsing issues
+- Contains:
+  - Embedded wildcard syntax: `__wildcard__` as literal text
+  - Dynamic prompt syntax: `{option|option}` as literal text
+  - Regex special chars: `.`, `*`, `+`, `?`, `|`, `\`, `$`, `^`
+  - Quote characters: `"`, `'`, `` ` ``
+  - HTML special chars: `&`, `<`, `>`, `=`
+- Expected: Special chars treated as literal text in final output
+
+**test_edge_case_insensitive.txt**
+- Purpose: Validate case-insensitive wildcard matching
+- Contains: Options in various case patterns
+- Expected: `__test_edge_case_insensitive__` and `__TEST_EDGE_CASE_INSENSITIVE__` return same results
+
+**test_comments.txt**
+- Purpose: Test comment handling with `#` prefix
+- Contains: Lines starting with `#` mixed with valid options
+- Expected: Comment lines ignored, only non-comment lines selected
+
+### 4. Deep Nesting Tests (7 levels)
+
+**test_nesting_level1.txt → test_nesting_level7.txt**
+- Purpose: Test transitive wildcard expansion up to 7 levels
+- Structure:
+  - Level 1 → references Level 2
+  - Level 2 → references Level 3
+  - ...
+  - Level 7 → final options (no further references)
+- Usage: Access `__test_nesting_level1__` to trigger 7-level expansion
+- Expected: All levels expand correctly, result from level 7 appears
+
+### 5. Syntax Feature Tests
+
+**test_quantifier.txt**
+- Purpose: Test quantifier syntax `N#__wildcard__`
+- Contains: List of color options
+- Usage: `3#__test_quantifier__` should expand to 3 repeated wildcards
+- Expected: Correct repetition and expansion
+
+**test_pattern_match.txt**
+- Purpose: Test pattern matching `__*/name__`
+- Contains: Options with identifiable pattern
+- Usage: `__*/test_pattern_match__` should match this file
+- Expected: Depth-agnostic matching works correctly
+
+## Test Usage Examples
+
+### Basic Test
+```bash
+curl -X POST http://127.0.0.1:8188/impact/wildcards \
+  -H "Content-Type: application/json" \
+  -d '{"text": "__test_encoding_emoji__", "seed": 42}'
+```
+
+### Nesting Test
+```bash
+curl -X POST http://127.0.0.1:8188/impact/wildcards \
+  -H "Content-Type: application/json" \
+  -d '{"text": "__test_nesting_level1__", "seed": 42}'
+```
+
+### Error Handling Test
+```bash
+curl -X POST http://127.0.0.1:8188/impact/wildcards \
+  -H "Content-Type: application/json" \
+  -d '{"text": "__test_error_cases__", "seed": 42}'
+```
+
+### Circular Reference Test
+```bash
+curl -X POST http://127.0.0.1:8188/impact/wildcards \
+  -H "Content-Type: application/json" \
+  -d '{"text": "__test_circular_a__", "seed": 42}'
+```
+
+### Quantifier Test
+```bash
+curl -X POST http://127.0.0.1:8188/impact/wildcards \

+```
+
+### Pattern Matching Test
+```bash
+curl -X POST http://127.0.0.1:8188/impact/wildcards \
+  -H "Content-Type: application/json" \
+  -d '{"text": "__*/test_pattern_match__", "seed": 42}'
+```
+
+## Test Coverage
+
+These test files address the following critical gaps identified in the test coverage analysis:
+
+1. ✅ **Error Handling** - Missing wildcard files, circular references
+2. ✅ **UTF-8 Encoding** - Multi-language support (emoji, CJK, RTL)
+3. ✅ **Edge Cases** - Empty lines, whitespace, long lines, special chars
+4. ✅ **Deep Nesting** - 7-level transitive expansion
+5. ✅ **Comment Handling** - Lines starting with `#`
+6. ✅ **Case Insensitivity** - Case-insensitive wildcard matching
+7. ✅ **Pattern Matching** - `__*/name__` syntax
+8. ✅ **Quantifiers** - `N#__wildcard__` syntax
+
+## Expected Test Results
+
+All tests should:
+- Not crash the system
+- Return valid results or graceful error messages
+- Preserve character encoding correctly
+- Handle edge cases without data corruption
+- Respect the 100-iteration limit for circular references
+- Demonstrate deterministic behavior with same seed
