+# ๐ฉ Tuxedo Link
+
+**AI-Powered Cat Adoption Search Engine**
+
+Find your perfect feline companion using AI, semantic search, and multi-platform aggregation.
+
+*In loving memory of Kyra ๐ฑ*
+
+---
+
+## ๐ Features
+
+โ **Multi-Platform Search** - Aggregates from Petfinder and RescueGroups
+โ **Natural Language** - Describe your ideal cat in plain English
+โ **Semantic Matching** - AI understands personality, not just keywords
+โ **Color/Breed Matching** - 3-tier system handles typos ("tuxado" โ "tuxedo", "main coon" โ "Maine Coon")
+โ **Deduplication** - Multi-modal (name + description + image) duplicate detection
+โ **Hybrid Search** - Combines vector similarity with structured filters
+โ **Image Recognition** - Uses CLIP to match cats visually
+โ **Email Notifications** - Get alerts for new matches
+โ **Serverless Backend** - Optionally deploy to Modal for cloud-based search and alerts
+
+**Technical Stack**: OpenAI GPT-4 โข ChromaDB โข CLIP โข Gradio โข Modal
+
+## ๐๏ธ Architecture Modes
+
+Tuxedo Link supports two deployment modes:
+
+### Local Mode (Development)
+- All components run locally
+- Uses local database and vector store
+- Fast iteration and development
+- No Modal required
+
+### Production Mode (Cloud)
+- UI runs locally, backend runs on Modal
+- Database and vector store on Modal volumes
+- Scheduled email alerts active
+- Scalable and serverless
+
+Switch between modes in `config.yaml` by setting `deployment.mode` to `local` or `production`.
+
+---
+
+## ๐ Quick Start
+
+### Prerequisites
+- Python 3.11+
+- `uv` package manager
+- API keys (OpenAI, Petfinder, Mailgun)
+### Installation
+
+1. **Navigate to project directory**
+```bash
+cd week8/community_contributions/dkisselev-zz/tuxedo_link
+```
+
+2. **Set up virtual environment**
+```bash
+uv venv
+source .venv/bin/activate
+uv pip install -e ".[dev]"
+```
+
+3. **Configure environment variables**
+```bash
+# Copy template and add your API keys
+cp env.example .env
+# Edit .env with your keys
+```
+
+4. **Configure application settings**
+```bash
+# Copy configuration template
+cp config.example.yaml config.yaml
+# Edit config.yaml for email provider and deployment mode
+```
+
+5. **Initialize databases**
+```bash
+python setup_vectordb.py
+```
+
+6. **Run the application**
+```bash
+./run.sh
+```
+
+Visit http://localhost:7860 in your browser!
+
+---
+
+## ๐ API Setup
+
+### Required API Keys
+
+Add these to your `.env` file:
+
+```bash
+# OpenAI (for profile extraction)
+# Get key from: https://platform.openai.com/api-keys
+OPENAI_API_KEY=sk-...
+
+# Petfinder (for cat listings)
+# Get key from: https://www.petfinder.com/developers/
+PETFINDER_API_KEY=your_key
+PETFINDER_SECRET=your_secret
+
+# Mailgun (for email alerts)
+# Get key from: https://app.mailgun.com/
+MAILGUN_API_KEY=your_mailgun_key
+```
+
+### Optional API Keys
+
+```bash
+# RescueGroups (additional cat listings)
+# Get key from: https://userguide.rescuegroups.org/
+RESCUEGROUPS_API_KEY=your_key
+
+# SendGrid (alternative email provider)
+SENDGRID_API_KEY=SG...
+
+# Modal (for cloud deployment)
+MODAL_TOKEN_ID=...
+MODAL_TOKEN_SECRET=...
+```
+
+### Application Configuration
+
+Edit `config.yaml` to configure:
+
+```yaml
+# Email provider (mailgun or sendgrid)
+email:
+ provider: mailgun
+ from_name: "Tuxedo Link"
+ from_email: "noreply@yourdomain.com"
+
+# Mailgun domain
+mailgun:
+ domain: "your-domain.mailgun.org"
+
+# Deployment mode (local or production)
+deployment:
+ mode: local # Use 'local' for development
+```
+
+**Note**: API keys go in `.env` (git-ignored), application settings go in `config.yaml` (also git-ignored).
+
+---
+
+## ๐ป Usage
+
+### Search Tab
+1. Describe your ideal cat in natural language
+2. Click "Search" or press Enter
+3. Browse results with match scores
+4. Click "View Details" to see adoption page
+
+**Example queries:**
+- "I want a friendly family cat in NYC good with children"
+- "Looking for a playful young kitten"
+- "Show me calm adult cats that like to cuddle"
+- "Find me a tuxedo maine coon in Boston" (natural color/breed terms work!)
+- "Orange tabby that's good with other cats"
+
+#### Alerts Tab
+1. Perform a search in the Search tab first
+2. Go to Alerts tab
+3. Enter your email address
+4. Choose notification frequency (Immediately, Daily, Weekly)
+5. Click "Save Alert"
+
+You'll receive email notifications when new matches are found!
+
+#### About Tab
+Learn about Kyra and the technology behind the app
+
+### Development Mode
+
+For faster development and testing, use local mode in `config.yaml`:
+
+```yaml
+deployment:
+ mode: local # Uses local database and cached data
+```

+ ## In Loving Memory of Kyra ๐ฑ
+
+ This application is dedicated to **Kyra**, a beloved companion who brought joy,
+ comfort, and unconditional love to our lives. Kyra was more than just a catโ
+ he was family, a friend, and a constant source of happiness.
+
+ ### The Inspiration
+
+ Kyra Link was created to help others find their perfect feline companion,
+ just as Kyra found his way into our hearts. Every cat deserves a loving home,
+ and every person deserves the companionship of a wonderful cat like Kyra.
+
+ ### The Technology
+
+ This application uses AI and machine learning to match prospective
+ adopters with their ideal cat:
+
+ - **Natural Language Processing**: Understand your preferences in plain English
+ - **Semantic Search**: Find cats based on personality, not just keywords
+ - **Multi-Source Aggregation**: Search across multiple adoption platforms
+ - **Smart Deduplication**: Remove duplicate listings using AI
+ - **Image Recognition**: Match cats visually using computer vision
+ - **Hybrid Matching**: Combine semantic understanding with structured filters
+
+ ### Features
+
+ โ **Multi-Platform Search**: Petfinder, RescueGroups
+ โ **AI-Powered Matching**: Semantic search with vector embeddings
+ โ **Smart Deduplication**: Name, description, and image similarity
+ โ **Personality Matching**: Find cats that match your lifestyle
+ โ **Location-Based**: Search near you with customizable radius
+
+ ### Technical Stack
+
+ - **Frontend**: Gradio
+ - **Backend**: Python with Modal serverless
+ - **LLMs**: OpenAI GPT-4 for profile extraction
+ - **Vector DB**: ChromaDB with SentenceTransformers
+ - **Image AI**: CLIP for visual similarity
+ - **APIs**: Petfinder, RescueGroups, SendGrid
+ - **Database**: SQLite for caching and user management
+
+ ### Open Source
+
+ Tuxedo Link is open source and built as part of the Andela LLM Engineering bootcamp.
+ Contributions and improvements are welcome!
+
+ ### Acknowledgments
+
+ - **Petfinder**: For their comprehensive pet adoption API
+ - **RescueGroups**: For connecting rescues with adopters
+ - **Andela**: For the LLM Engineering bootcamp
+ - **Kyra**: For inspiring this project and bringing so much joy ๐

+## ๐ Modal Deployment Guide
+
+How to deploy Tuxedo Link to Modal for production use.
+
+---
+
+## ๐๏ธ Production Architecture
+
+In production mode, Tuxedo Link uses a **hybrid architecture**:
+
+### Component Distribution
+
+**Local (Your Computer)**:
+- Gradio UI (`app.py`) - User interface only
+- No heavy ML models loaded
+- Fast startup
+
+**Modal (Cloud)**:
+- `modal_api.py` - Main API functions (profile extraction, search, alerts)
+- `scheduled_search.py` - Scheduled jobs (daily/weekly alerts, cleanup)
+- Database (SQLite on Modal volume)
+- Vector DB (ChromaDB on Modal volume)
+- All ML models (GPT-4, SentenceTransformer, CLIP)
+
+### Communication Flow
+
+```
+User โ Gradio UI (local) โ modal.Function.from_name().remote() โ Modal API โ Response โ UI
+```
+
+**Key Functions Exposed by Modal**:
+1. `extract_profile` - Convert natural language to CatProfile
+2. `search_cats` - Execute complete search pipeline
+3. `create_alert_and_notify` - Create alert with optional immediate email
+4. `get_alerts` / `update_alert` / `delete_alert` - Alert management
+
+---
+
+## ๐ Quick Start (Automated Deployment)
+
+The easiest way to deploy is using the automated deployment script:
+
+```bash
+cd week8/community_contributions/dkisselev-zz/tuxedo_link
+
+# 1. Configure config.yaml for production
+cp config.example.yaml config.yaml
+# Edit config.yaml and set deployment.mode to 'production'
+
+# 2. Ensure environment variables are set
+# Load from .env or set manually:
+export OPENAI_API_KEY=sk-...
+export PETFINDER_API_KEY=...
+export PETFINDER_SECRET=...
+export RESCUEGROUPS_API_KEY=...
+export MAILGUN_API_KEY=...
+
+# 3. Run deployment script
+./deploy.sh
+```
+
+The script will automatically:
+- โ Validate Modal authentication
+- โ Check configuration
+- โ Create/update Modal secrets
+- โ Create Modal volume
+- โ Upload config.yaml to Modal
+- โ Deploy scheduled search services

+
+## Configuration System
+
+**File**: `utils/config.py`
+**Purpose**: Centralized YAML-based configuration management with environment variable overrides
+
+### Overview
+
+The configuration system separates API keys (in `.env`) from application settings (in `config.yaml`), enabling:
+- Deployment mode switching (local vs production)
+- Email provider selection
+- Database path configuration
+- Easy configuration without code changes
+
+### Core Functions
+
+#### 1. `load_config()`
+
+**Purpose**: Load and cache configuration from YAML file.
+
+**Signature**:
+```python
+def load_config() -> Dict[str, Any]
+```
+
+**Returns**: Complete configuration dictionary
+
+**Behavior**:
+- First checks for `config.yaml`
+- Falls back to `config.example.yaml` if not found
+- Applies environment variable overrides
+- Caches result for performance
+
+**Example**:
+```python
+config = load_config()
+# Returns:
+# {
+# 'email': {'provider': 'mailgun', ...},
+# 'deployment': {'mode': 'local', ...},
+# ...
+# }
+```
+
+#### 2. `is_production()`
+
+**Purpose**: Check if running in production mode.
+
+**Signature**:
+```python
+def is_production() -> bool
+```
+
+**Returns**: `True` if `deployment.mode == 'production'`, else `False`
+
+**Usage**:
+```python
+if is_production():
+ # Use Modal remote functions
+ send_immediate_notification.remote(alert_id)
+else:
+ # Local mode - can't send immediate notifications
+ print("Immediate notifications only available in production")
+```
+
+#### 3. `get_db_path()` / `get_vectordb_path()`
+
+**Purpose**: Get database paths based on deployment mode.
+
+**Signature**:
+```python
+def get_db_path() -> str
+def get_vectordb_path() -> str
+```
+
+**Returns**:
+- Local mode: `"data/tuxedo_link.db"`, `"cat_vectorstore"`
+- Production mode: `"/data/tuxedo_link.db"`, `"/data/cat_vectorstore"`
+
+**Example**:
+```python
+db_path = get_db_path() # Automatically correct for current mode
+db_manager = DatabaseManager(db_path)
+```
+
+#### 4. `get_email_provider()` / `get_email_config()` / `get_mailgun_config()`
+
+**Purpose**: Get email-related configuration.
+
+**Signatures**:
+```python
+def get_email_provider() -> str # Returns "mailgun" or "sendgrid"
+def get_email_config() -> Dict[str, str] # Returns from_name, from_email
+def get_mailgun_config() -> Dict[str, str] # Returns domain
+```
+
+**Example**:
+```python
+provider_name = get_email_provider() # "mailgun"
+email_cfg = get_email_config()
+# {'from_name': 'Tuxedo Link', 'from_email': 'noreply@...'}
+```
+
+### Configuration File Structure
+
+**`config.yaml`**:
+```yaml
+email:
+ provider: mailgun
+ from_name: "Tuxedo Link"
+ from_email: "noreply@example.com"
+
+mailgun:
+ domain: "sandbox123.mailgun.org"
+
+deployment:
+ mode: local # or production
+ local:
+ db_path: "data/tuxedo_link.db"
+ vectordb_path: "cat_vectorstore"
+ production:
+ db_path: "/data/tuxedo_link.db"
+ vectordb_path: "/data/cat_vectorstore"
+```
+
+### Environment Overrides
+
+Environment variables can override config:
+```bash
+export EMAIL_PROVIDER=sendgrid # Overrides config.yaml
+export DEPLOYMENT_MODE=production
+```
+
+---
+
+## Email Provider System
+
+**Files**: `agents/email_providers/*.py`
+**Purpose**: Pluggable email backend system supporting multiple providers
+
+### Architecture
+
+```
+EmailAgent
+ โ
+get_email_provider() [factory.py]
+ โ
+โโโ MailgunProvider [mailgun_provider.py]
+โโโ SendGridProvider [sendgrid_provider.py] (stub)
+ โ
+send_email() via requests or API
+```
+
+### Core Components
+
+#### 1. `EmailProvider` (Base Class)
+
+**File**: `agents/email_providers/base.py`
+
+**Purpose**: Abstract interface all providers must implement.
+
+**Methods**:
+```python
+class EmailProvider(ABC):
+ @abstractmethod
+ def send_email(
+ self,
+ to: str,
+ subject: str,
+ html: str,
+ text: str,
+ from_email: Optional[str] = None,
+ from_name: Optional[str] = None
+ ) -> bool:
+ pass
+
+ @abstractmethod
+ def get_provider_name(self) -> str:
+ pass
+```
+
+#### 2. `MailgunProvider`
+
+**File**: `agents/email_providers/mailgun_provider.py`
+
+**Purpose**: Full Mailgun API implementation using requests library.
+
+**Initialization**:
+```python
+provider = MailgunProvider()
+# Reads:
+# - MAILGUN_API_KEY from environment
+# - mailgun.domain from config.yaml
+# - email.from_name, email.from_email from config.yaml
+```
+
+**Key Methods**:
+
+**`send_email()`**:
+```python
+def send_email(
+ to: str,
+ subject: str,
+ html: str,
+ text: str,
+ from_email: Optional[str] = None,
+ from_name: Optional[str] = None
+) -> bool
+```
+
+**Example**:
+```python
+provider = MailgunProvider()
+success = provider.send_email(
+ to="user@example.com",
+ subject="New Cat Matches!",
+ html="
Found 5 matches
...",
+ text="Found 5 matches..."
+)
+# Returns: True if sent, False if failed
+```
+
+**Implementation Details**:
+- Uses `requests.post()` with `auth=("api", api_key)`
+- Sends to `https://api.mailgun.net/v3/{domain}/messages`
+- Returns `True` on status 200, `False` otherwise
+- Logs all operations for debugging
+
+#### 3. `SendGridProvider` (Stub)
+
+**File**: `agents/email_providers/sendgrid_provider.py`
+
+**Purpose**: Stub implementation for testing/backwards compatibility.
+
+**Behavior**:
+- Always returns `True` (simulates success)
+- Logs what would be sent (doesn't actually send)
+- Useful for testing without API calls
+
+**Example**:
+```python
+provider = SendGridProvider()
+success = provider.send_email(...) # Always True
+# Logs: "[STUB] Would send email via SendGrid to user@example.com"
+```
+
+#### 4. `get_email_provider()` (Factory)
+
+**File**: `agents/email_providers/factory.py`
+
+**Purpose**: Create provider instance based on configuration.
+
+**Signature**:
+```python
+def get_email_provider(provider_name: Optional[str] = None) -> EmailProvider
+```
+
+**Parameters**:
+- `provider_name`: Optional override (default: reads from config)
+
+**Returns**: Configured provider instance
+
+**Example**:
+```python
+# Use configured provider
+provider = get_email_provider() # Reads config.yaml
+
+# Or specify explicitly
+provider = get_email_provider('mailgun')
+provider = get_email_provider('sendgrid')
+```
+
+### Integration with EmailAgent
+
+**File**: `agents/email_agent.py`
+
+**Modified** to use provider system:
+```python
+class EmailAgent(Agent):
+ def __init__(self, provider: Optional[EmailProvider] = None):
+ self.provider = provider or get_email_provider()
+ self.enabled = True if self.provider else False
+
+ def send_match_notification(self, alert, matches):
+ # Build HTML/text templates
+ html = self._build_match_html(matches, alert)
+ text = self._build_match_text(matches)
+
+ # Send via provider
+ success = self.provider.send_email(
+ to=alert.user_email,
+ subject=f"๐ฑ {len(matches)} New Cat Matches!",
+ html=html,
+ text=text
+ )
+ return success
+```
+
+## Semantic Color/Breed Matching
+
+**NEW in v2.1** - 3-tier intelligent normalization system for color and breed terms.
+
+### Overview
+
+The semantic matching system ensures user queries like "find me a tuxedo maine coon" are correctly translated to API values, even with typos ("tuxado", "main coon"). It uses a **3-tier strategy**:
+
+1. **Dictionary Lookup** (< 1ms) - Common terms mapped instantly
+2. **Vector DB Search** (10-50ms) - Fuzzy matching for typos
+3. **String Matching** (< 1ms) - Fallback for edge cases
+
+### Architecture
+
+```
+User Input โ Profile Agent โ Planning Agent โ API Call
+ โ (extract) โ (normalize)
+ "tuxedo" 1. Dictionary โ "Black & White / Tuxedo"
+ 2. Vector DB โ (if not found)
+ 3. Fallback โ (if still not found)
+```
+
+### Components
+
+#### 1. Metadata Vector Database (`setup_metadata_vectordb.py`)
+
+Separate ChromaDB for color/breed fuzzy matching.
+
+**Class**: `MetadataVectorDB`
+
+**Initialization**:
+```python
+from setup_metadata_vectordb import MetadataVectorDB
+
+vectordb = MetadataVectorDB("metadata_vectorstore")
+```
+
+**Key Methods**:
+
+##### `index_colors(valid_colors: List[str], source: str)`
+
+Indexes color values from an API.
+
+```python
+colors = ["Black", "White", "Black & White / Tuxedo"]
+vectordb.index_colors(colors, source="petfinder")
+```
+
+##### `index_breeds(valid_breeds: List[str], source: str)`
+
+Indexes breed values from an API.
+
+```python
+breeds = ["Siamese", "Maine Coon", "Ragdoll"]
+vectordb.index_breeds(breeds, source="petfinder")
+```
+
+##### `search_color(user_term: str, n_results: int = 1, source_filter: Optional[str] = None)`
+
+Find most similar color via semantic search.
+
+**Returns**: `List[Dict]` with keys: `color`, `distance`, `similarity`, `source`
+
+```python
+results = vectordb.search_color("tuxado", n_results=1)
+# [{"color": "Black & White / Tuxedo", "similarity": 0.85, "source": "petfinder"}]
+```
+
+##### `search_breed(user_term: str, n_results: int = 1, source_filter: Optional[str] = None)`
+
+Find most similar breed via semantic search.
+
+```python
+results = vectordb.search_breed("ragdol", n_results=1)
+# [{"breed": "Ragdoll", "similarity": 0.92, "source": "petfinder"}]
+```
+
+##### `get_stats()`
+
+Get statistics about indexed data.
+
+```python
+stats = vectordb.get_stats()
+# {"colors_count": 48, "breeds_count": 102}
+```
+
+---
+
+#### 2. Color Mapping (`utils/color_mapping.py`)
+
+Normalizes user color terms to valid API values.
+
+**Dictionary**: `USER_TERM_TO_API_COLOR` - 40+ mappings
+
+**Key examples**:
+- `"tuxedo"` โ `["Black & White / Tuxedo"]`
+- `"orange tabby"` โ `["Tabby (Orange / Red)"]`
+- `"gray"` / `"grey"` โ `["Gray / Blue / Silver"]`
+
+##### `normalize_user_colors(user_colors, valid_api_colors, vectordb=None, source="petfinder", similarity_threshold=0.7)`
+
+3-tier normalization for colors.
+
+**Parameters**:
+- `user_colors`: List of user color terms
+- `valid_api_colors`: Valid colors from API
+- `vectordb`: Optional MetadataVectorDB for fuzzy matching
+- `source`: API source filter ("petfinder"/"rescuegroups")
+- `similarity_threshold`: Minimum similarity (0-1) for vector matches
+
+**Returns**: `List[str]` - Valid API color values
+
+**Example**:
+```python
+from utils.color_mapping import normalize_user_colors
+
+valid_colors = ["Black", "White", "Black & White / Tuxedo"]
+
+# Tier 1: Dictionary
+result = normalize_user_colors(["tuxedo"], valid_colors)
+# ["Black & White / Tuxedo"]
+
+# Tier 2: Vector DB (with typo)
+result = normalize_user_colors(
+ ["tuxado"], # Typo!
+ valid_colors,
+ vectordb=metadata_vectordb,
+ source="petfinder",
+ similarity_threshold=0.6
+)
+# ["Black & White / Tuxedo"] (if similarity >= 0.6)
+
+# Tier 3: Fallback
+result = normalize_user_colors(["Black"], valid_colors)
+# ["Black"] (exact match)
+```
+
+**Logging**:
+```
+๐ฏ Dictionary match: 'tuxedo' โ ['Black & White / Tuxedo']
+๐ Vector match: 'tuxado' โ 'Black & White / Tuxedo' (similarity: 0.85)
+โ Exact match: 'Black' โ 'Black'
+โ Substring match: 'tabby' โ 'Tabby (Brown / Chocolate)'
+โ ๏ธ No color match found for 'invalid_color'
+```
+
+##### `get_color_suggestions(color_term, valid_colors, top_n=5)`
+
+Get color suggestions for autocomplete.
+
+```python
+suggestions = get_color_suggestions("tab", valid_colors, top_n=3)
+# ["Tabby (Brown / Chocolate)", "Tabby (Orange / Red)", "Tabby (Gray / Blue / Silver)"]
+```
+
+---
+
+#### 3. Breed Mapping (`utils/breed_mapping.py`)
+
+Normalizes user breed terms to valid API values.
+
+**Dictionary**: `USER_TERM_TO_API_BREED` - 30+ mappings
+
+**Key examples**:
+- `"main coon"` โ `["Maine Coon"]`
+- `"ragdol"` โ `["Ragdoll"]`
+- `"sphinx"` โ `["Sphynx"]`
+- `"dsh"` โ `["Domestic Short Hair"]`
+- `"mixed"` โ `["Mixed Breed", "Domestic Short Hair", ...]`
+
+##### `normalize_user_breeds(user_breeds, valid_api_breeds, vectordb=None, source="petfinder", similarity_threshold=0.7)`
+
+3-tier normalization for breeds.
+
+**Parameters**: Same as `normalize_user_colors`
+
+**Returns**: `List[str]` - Valid API breed values
+
+**Example**:
+```python
+from utils.breed_mapping import normalize_user_breeds
+
+valid_breeds = ["Siamese", "Maine Coon", "Ragdoll"]
+
+# Tier 1: Dictionary (typo correction)
+result = normalize_user_breeds(["main coon"], valid_breeds)
+# ["Maine Coon"]
+
+# Tier 2: Vector DB
+result = normalize_user_breeds(
+ ["ragdol"],
+ valid_breeds,
+ vectordb=metadata_vectordb,
+ source="petfinder"
+)
+# ["Ragdoll"]
+
+# Special: Mixed breeds
+result = normalize_user_breeds(["mixed"], valid_breeds)
+# ["Mixed Breed", "Domestic Short Hair", "Domestic Medium Hair"]
+```
+
+##### `get_breed_suggestions(breed_term, valid_breeds, top_n=5)`
+
+Get breed suggestions for autocomplete.
+
+```python
+suggestions = get_breed_suggestions("short", valid_breeds, top_n=3)
+# ["Domestic Short Hair", "British Shorthair", "American Shorthair"]
+```
+
+---
+
+#### 4. Agent Integration
+
+##### PetfinderAgent
+
+**New Methods**:
+
+###### `get_valid_colors() -> List[str]`
+
+Fetch all valid cat colors from Petfinder API (`/v2/types/cat`).
+
+**Returns**: 30 colors (cached)
+
+```python
+agent = PetfinderAgent()
+colors = agent.get_valid_colors()
+# ["Black", "Black & White / Tuxedo", "Blue Cream", ...]
+```
+
+###### `get_valid_breeds() -> List[str]`
+
+Fetch all valid cat breeds from Petfinder API (`/v2/types/cat/breeds`).
+
+**Returns**: 68 breeds (cached)
+
+```python
+breeds = agent.get_valid_breeds()
+# ["Abyssinian", "American Curl", "American Shorthair", ...]
+```
+
+###### `search_cats(..., color: Optional[List[str]], breed: Optional[List[str]], ...)`
+
+Search with **normalized** color and breed values.
+
+```python
+# User says "tuxedo maine coon"
+# Planning agent normalizes:
+# - "tuxedo" โ ["Black & White / Tuxedo"]
+# - "maine coon" โ ["Maine Coon"]
+
+results = agent.search_cats(
+ location="NYC",
+ color=["Black & White / Tuxedo"], # Normalized!
+ breed=["Maine Coon"], # Normalized!
+ limit=100
+)
+```
+
+---
+
+##### RescueGroupsAgent
+
+**New Methods**:
+
+###### `get_valid_colors() -> List[str]`
+
+Fetch all valid cat colors from RescueGroups API (`/v5/public/animals/colors`).
+
+**Returns**: 597 colors (cached)
+
+```python
+agent = RescueGroupsAgent()
+colors = agent.get_valid_colors()
+# ["Black", "White", "Gray", "Orange", "Tuxedo", ...]
+```
+
+###### `get_valid_breeds() -> List[str]`
+
+Fetch all valid cat breeds from RescueGroups API (`/v5/public/animals/breeds`).
+
+**Returns**: 807 breeds (cached)
+
+```python
+breeds = agent.get_valid_breeds()
+# ["Domestic Short Hair", "Siamese", "Maine Coon", ...]
+```
+
+###### `search_cats(..., color: Optional[List[str]], breed: Optional[List[str]], ...)`
+
+**Note**: RescueGroups API doesn't support direct color/breed filtering. Values are logged but filtered client-side.
+
+```python
+results = agent.search_cats(
+ location="NYC",
+ color=["Tuxedo"], # Logged, filtered client-side
+ breed=["Maine Coon"] # Logged, filtered client-side
+)
+```
+
+---
+
+##### PlanningAgent
+
+**Modified Methods**:
+
+###### `_search_petfinder(profile: CatProfile)`
+
+Now normalizes colors and breeds before API call.
+
+```python
+# User profile
+profile = CatProfile(
+ color_preferences=["tuxedo", "orange tabby"],
+ preferred_breeds=["main coon", "ragdol"] # Typos!
+)
+
+# Planning agent normalizes:
+# 1. Fetches valid colors/breeds from API
+# 2. Runs 3-tier normalization
+# 3. Passes normalized values to API
+
+# Logs:
+# โ Colors: ['tuxedo', 'orange tabby'] โ ['Black & White / Tuxedo', 'Tabby (Orange / Red)']
+# โ Breeds: ['main coon', 'ragdol'] โ ['Maine Coon', 'Ragdoll']
+```
+
+---
+
+#### 5. Framework Integration
+
+##### TuxedoLinkFramework
+
+**New Initialization Step**: `_index_metadata()`
+
+Called during framework initialization to populate metadata vector DB.
+
+```python
+def _index_metadata(self):
+ """Index colors and breeds from APIs."""
+
+ # Fetch and index Petfinder
+ petfinder = PetfinderAgent()
+ colors = petfinder.get_valid_colors() # 30 colors
+ breeds = petfinder.get_valid_breeds() # 68 breeds
+ self.metadata_vectordb.index_colors(colors, source="petfinder")
+ self.metadata_vectordb.index_breeds(breeds, source="petfinder")
+
+ # Fetch and index RescueGroups
+ rescuegroups = RescueGroupsAgent()
+ colors = rescuegroups.get_valid_colors() # 597 colors
+ breeds = rescuegroups.get_valid_breeds() # 807 breeds
+ self.metadata_vectordb.index_colors(colors, source="rescuegroups")
+ self.metadata_vectordb.index_breeds(breeds, source="rescuegroups")
+
+ # Log stats
+ stats = self.metadata_vectordb.get_stats()
+ # โ Metadata indexed: 48 colors, 102 breeds
+```
+
+**Performance**: ~2-5 seconds on first run, then cached.
+
+---
+
+### Complete Flow Example
+
+```python
+from cat_adoption_framework import TuxedoLinkFramework
+from models.cats import CatProfile
+
+# 1. Initialize framework (auto-indexes metadata)
+framework = TuxedoLinkFramework()
+# [INFO] โ Fetched 30 valid colors from Petfinder
+# [INFO] โ Fetched 68 valid breeds from Petfinder
+# [INFO] โ Fetched 597 valid colors from RescueGroups
+# [INFO] โ Fetched 807 valid breeds from RescueGroups
+# [INFO] โ Metadata indexed: 48 colors, 102 breeds
+
+# 2. User searches with natural language (with typos!)
+profile = CatProfile(
+ user_location="Boston, MA",
+ color_preferences=["tuxado", "ornage tabby"], # Typos!
+ preferred_breeds=["main coon", "ragdol"], # Typos!
+ max_distance=50
+)
+
+# 3. Framework normalizes and searches
+result = framework.search(profile)
+
+# Behind the scenes:
+# [INFO] ๐ฏ Dictionary match: 'main coon' โ ['Maine Coon']
+# [INFO] ๐ฏ Dictionary match: 'ragdol' โ ['Ragdoll']
+# [INFO] ๐ Vector match: 'tuxado' โ 'Black & White / Tuxedo' (similarity: 0.85)
+# [INFO] ๐ Vector match: 'ornage tabby' โ 'Tabby (Orange / Red)' (similarity: 0.78)
+# [INFO] โ Colors: ['tuxado', 'ornage tabby'] โ ['Black & White / Tuxedo', 'Tabby (Orange / Red)']
+# [INFO] โ Breeds: ['main coon', 'ragdol'] โ ['Maine Coon', 'Ragdoll']
+
+# 4. APIs receive normalized values
+# Petfinder.search_cats(color=['Black & White / Tuxedo', 'Tabby (Orange / Red)'], breed=['Maine Coon', 'Ragdoll'])
+# RescueGroups.search_cats(color=['Black & White / Tuxedo', 'Tabby (Orange / Red)'], breed=['Maine Coon', 'Ragdoll'])
+
+# 5. Results returned
+print(f"Found {len(result.matches)} matches!")
+```
+
+---
+
+### Configuration
+
+No configuration needed! The system:
+- โ Automatically fetches valid colors/breeds from APIs
+- โ Indexes them on startup (persisted to disk)
+- โ Uses 3-tier strategy transparently
+- โ Logs all normalization steps for debugging
+
+**Optional**: Adjust similarity threshold in planning agent:
+
+```python
+# In agents/planning_agent.py
+api_colors = normalize_user_colors(
+ profile.color_preferences,
+ valid_colors,
+ vectordb=self.metadata_vectordb,
+ source="petfinder",
+ similarity_threshold=0.8 # Default: 0.7
+)
+```
+
+---
+
+### Summary
+
+The semantic color/breed matching system provides:
+
+โ **Natural Language**: Users can use terms like "tuxedo", "orange tabby"
+โ **Typo Tolerance**: "tuxado" โ "tuxedo", "main coon" โ "Maine Coon"
+โ **3-Tier Strategy**: Dictionary โ Vector โ Fallback (99%+ coverage)
+โ **Fast**: < 50ms overhead per search
+โ **Automatic**: No configuration required
+โ **Multi-API**: Works with Petfinder & RescueGroups
+โ **Well-Tested**: 46 unit tests + 8 integration tests
+โ **Extensible**: Easy to add new mappings or APIs
+
+**Impact**: Users can now search naturally without needing to know exact API color/breed values, resulting in better search results and improved adoption rates! ๐ฑ

+```
+
+**Integration**:
+```
+Called by:
+ โ daily_search_job() (cron: daily at 9 AM)
+ โ weekly_search_job() (cron: Monday at 9 AM)
+```
+
+**Flow**:
+```python
+# Executed on Modal cloud

+
+# Process:
+# 1. Load all active alerts from database
+# 2. For each alert:
+# a. Run cat search with saved profile
+# b. Filter out cats already seen
+# c. If new matches found:

+# - Update last_sent timestamp
+# - Store match IDs to avoid duplicates
+# 3. Log completion
+```
+
+**Example**:
+```
+[2024-10-29 09:00:00] Starting scheduled search job
+Found 15 active alerts
+
+Processing alert 1 for user@example.com
+ Found 3 new matches for alert 1
+ Email sent successfully for alert 1
+
+Processing alert 2 for other@example.com
+ No new matches for alert 2

+
+---
+
+##### `cleanup_old_data()`
+
+**Purpose**: Remove cached cats older than N days.
+
+**Signature**:
+```python
+@app.function(

+# {
+# 'removed': 145,
+# 'kept': 250,
+# 'vector_db_size': 250
+# }
+```
+
+---
+
+### Modal Image Configuration
+
+Both Modal files use a carefully configured image with compatible package versions:
+
+```python
+from pathlib import Path
+import modal
+
+project_dir = Path(__file__).parent
+
+image = (
+ modal.Image.debian_slim(python_version="3.11")
+ .pip_install(
+ "openai",
+ "chromadb",
+ "requests",
+ "sentence-transformers==2.5.1", # Compatible with torch 2.2.2
+ "transformers==4.38.0", # Compatible with torch 2.2.2
+ "Pillow",
+ "python-dotenv",
+ "pydantic",
+ "geopy",
+ "pyyaml",
+ "python-levenshtein",
+ "open-clip-torch==2.24.0", # Compatible with torch 2.2.2
+ )
+ .apt_install("git")
+ .run_commands(
+ "pip install torch==2.2.2 torchvision==0.17.2 --index-url https://download.pytorch.org/whl/cpu",
+ "pip install numpy==1.26.4",
+ )
+ # Add only necessary source directories
+ .add_local_dir(str(project_dir / "models"), remote_path="/root/models")
+ .add_local_dir(str(project_dir / "agents"), remote_path="/root/agents")
+ .add_local_dir(str(project_dir / "database"), remote_path="/root/database")
+ .add_local_dir(str(project_dir / "utils"), remote_path="/root/utils")
+ # Add standalone Python files
+ .add_local_file(str(project_dir / "cat_adoption_framework.py"), remote_path="/root/cat_adoption_framework.py")
+ .add_local_file(str(project_dir / "setup_vectordb.py"), remote_path="/root/setup_vectordb.py")
+ .add_local_file(str(project_dir / "setup_metadata_vectordb.py"), remote_path="/root/setup_metadata_vectordb.py")
+ # Add config file
+ .add_local_file(str(project_dir / "config.yaml"), remote_path="/root/config.yaml")
+)
+```
+
+**Critical Points**:
+1. โ Modal files at project root for auto-discovery
+2. โ Top-level imports (not inside functions)
+3. โ Explicit `add_local_dir()` for each source directory
+4. โ Compatible package versions (torch 2.2.2, transformers 4.38.0, etc.)
+5. โ Only necessary files added (not `.venv`, `cat_vectorstore`, etc.)
+
+---
+
+### UI Integration with Modal
+
+**File**: `app.py`
+
+The UI uses conditional logic based on `is_production()` to either call Modal or use local framework:
+
+```python
+from utils.config import is_production
+
+if not is_production():
+ # LOCAL MODE: Import and initialize heavy components
+ from cat_adoption_framework import TuxedoLinkFramework
+ from agents.profile_agent import ProfileAgent
+
+ framework = TuxedoLinkFramework()
+ profile_agent = ProfileAgent()
+ print("โ Running in LOCAL mode - using local components")
+else:
+ # PRODUCTION MODE: Don't import heavy components - use Modal API
+ print("โ Running in PRODUCTION mode - using Modal API")
+```
+
+**Search Flow in Production**:
+
+```python
+def extract_profile_from_text(user_input: str, use_cache: bool = False):
+ if is_production():
+ # PRODUCTION: Call Modal API
+ import modal
+
+ # Extract profile via Modal
+ extract_profile_func = modal.Function.from_name("tuxedo-link-api", "extract_profile")
+ profile_result = extract_profile_func.remote(user_input)
+ profile = CatProfile(**profile_result["profile"])
+
+ # Search via Modal
+ search_cats_func = modal.Function.from_name("tuxedo-link-api", "search_cats")
+ search_result = search_cats_func.remote(profile.model_dump(), use_cache=use_cache)
+
+ # Reconstruct matches from Modal response
+ current_matches = [
+ CatMatch(
+ cat=Cat(**m["cat"]),
+ match_score=m["match_score"],
+ vector_similarity=m["vector_similarity"],
+ attribute_match_score=m["attribute_match_score"],
+ explanation=m["explanation"],
+ matching_attributes=m.get("matching_attributes", []),
+ missing_attributes=m.get("missing_attributes", [])
+ )
+ for m in search_result["matches"]
+ ]
+ else:
+ # LOCAL: Use local framework
+ profile = profile_agent.extract_profile([{"role": "user", "content": user_input}])
+ result = framework.search(profile, use_cache=use_cache)
+ current_matches = result.matches
+
+ # Rest of function same for both modes
+ return chat_history, results_html, profile_json
+```
+
+---
+
+### Deployment Process
+
+**See**: `docs/MODAL_DEPLOYMENT.md` for complete deployment guide

+
+## Complete User Journey Examples
+
+### Example 1: First-Time Search
+
+**User Action**: Types "friendly kitten in NYC, good with kids"
+
+**System Flow**:
+
+```python
+# 1. UI receives input
+user_text = "friendly kitten in NYC, good with kids"
+
+# 2. Convert to conversation format & extract profile
+profile_agent = ProfileAgent()
+conversation = [{"role": "user", "content": user_text}]
+profile = profile_agent.extract_profile(conversation)
+# โ OpenAI GPT-4 API call (with conversation format)
+# โ CatProfile(location="NYC", age_range=["kitten"], good_with_children=True)
+
+# 3. Execute search
+framework = TuxedoLinkFramework()
+result = framework.search(profile, use_cache=False)
+
+# 4. Planning agent orchestrates
+planner = PlanningAgent()
+
+# 4a. Fetch from APIs (parallel)
+petfinder_cats = PetfinderAgent().search_cats(
+ location="NYC",
+ age="kitten",
+ good_with_children=True
+) # Returns 45 cats
+
+rescuegroups_cats = RescueGroupsAgent().search_cats(
+ location="NYC",
+ age="kitten"
+) # Returns 38 cats
+
+# Total: 83 cats
+
+# 4b. Deduplicate
+dedup_agent = DeduplicationAgent()
+unique_cats = dedup_agent.deduplicate(cats)
+# Finds 8 duplicates (same cat on both platforms)
+# Unique: 75 cats
+
+# 4c. Cache with embeddings
+for cat in unique_cats:
+ db.cache_cat(cat, get_image_embedding(cat.primary_photo))
+
+# 4d. Add to vector DB
+vector_db.add_cats(unique_cats)
+
+# 4e. Match and rank
+matching_agent = MatchingAgent()
+matches = matching_agent.search(profile, top_k=20)
+
+# Vector search finds: 50 semantically similar
+# Metadata filter: 32 meet hard constraints
+# Hybrid scoring: Rank all 32
+# Return top 20
+
+# 5. Format and display
+html = build_results_grid(matches)
+
+# 6. Return to user (OpenAI messages format)
+return (
+ chat_history=[
+ {"role": "user", "content": "friendly kitten in NYC, good with kids"},
+ {"role": "assistant", "content": "โ Got it! Searching for...\n\nโจ Found 20 cats!"}
+ ],
+ results_html=html,
+ profile_display='{"user_location": "NYC", "age_range": ["kitten"], ...}'
+)
+```
+
+**Result**: User sees 20 cat cards with photos, match scores, and explanations.
+
+**Note**: Chat history now uses OpenAI messages format (Gradio `type="messages"`) instead of deprecated tuples format.
+
+---
+
+### Example 2: Cached Search (Developer Mode)
+
+**User Action**: Same search with "Use Cache" enabled
+
+**System Flow**:
+
+```python
+# 1-2. Same as above (extract profile)
+
+# 3. Execute search with cache
+result = framework.search(profile, use_cache=True)
+
+# 4. Planning agent uses cache
+cats = db.get_all_cached_cats(exclude_duplicates=True)
+# Returns: 75 cats (from previous search)
+
+# Skip API calls, deduplication, caching
+
+# 4a. Match and rank (same as before)
+matches = matching_agent.search(profile, top_k=20)
+
+# 5-6. Same as above (format and display)
+```
+
+**Result**:
+- Much faster (0.2s vs 13s)
+- No API calls (preserves rate limits)
+- Same quality results
+
+---
+
+### Example 3: Email Alert Flow
+
+**User Action**: Saves search as daily alert
+
+**Initial Setup**:
+```python
+# 1. User registers
+user_id = db.create_user(email="user@example.com", password_hash="...")
+
+# 2. User creates alert
+alert = AdoptionAlert(
+ user_id=user_id,
+ user_email="user@example.com",
+ profile=CatProfile(...), # Their search preferences
+ frequency="daily",
+ active=True
+)
+alert_id = db.create_alert(alert)
+```
+
+**Daily Scheduled Job** (Modal, 9 AM):
+```python
+# Runs on Modal cloud
+run_scheduled_searches()
+
+# 1. Load alerts
+alerts = db.get_active_alerts()
+# Returns: [AdoptionAlert(...), ...]
+
+# 2. For user's alert
+alert = alerts[0] # user@example.com
+
+# 3. Run search
+result = framework.search(alert.profile)
+# Returns: 18 matches
+
+# 4. Filter new matches
+last_seen_ids = alert.last_match_ids # ["pf_1", "pf_2", ...]
+new_matches = [
+ m for m in result.matches
+ if m.cat.id not in last_seen_ids
+]
+# New matches: 3 cats
+
+# 5. Send email
+email_agent = EmailAgent()
+email_agent.send_match_notification(alert, new_matches)
+
+# Email content:
+# Subject: "Tuxedo Link: 3 New Cat Matches!"
+# Body:
+# - Cat 1: Fluffy (85% match)
+# [Photo]
+# Great personality match, loves children
+# [View Details โ]
+#
+# - Cat 2: Max (82% match)
+# ...
+
+# 6. Update alert
+db.update_alert(
+ alert_id=alert.id,
+ last_sent=datetime.now(),
+ last_match_ids=[m.cat.id for m in new_matches]
+)
+```
+
+**Result**: User receives email with 3 new cats, won't see them again tomorrow.
+
+---
+
+### Example 4: Deduplication in Action
+
+**Scenario**: Same cat listed on Petfinder AND RescueGroups
+
+**Cat on Petfinder**:
+```python
+cat1 = Cat(
+ id="petfinder_12345",
+ name="Fluffy",
+ breed="Persian",
+ age="adult",
+ gender="female",
+ organization_name="Happy Paws Rescue",
+ description="Friendly lap cat who loves cuddles",
+ primary_photo="https://petfinder.com/photos/cat1.jpg"
+)
+```
+
+**Same Cat on RescueGroups**:
+```python
+cat2 = Cat(
+ id="rescuegroups_67890",
+ name="Fluffy (Happy Paws)",
+ breed="Persian",
+ age="adult",
+ gender="female",
+ organization_name="Happy Paws Rescue",
+ description="Sweet lap cat, loves to cuddle",
+ primary_photo="https://rescuegroups.org/photos/cat2.jpg"
+)
+```
+
+**Deduplication Process**:
+```python
+dedup_agent = DeduplicationAgent(db)
+unique = dedup_agent.deduplicate([cat1, cat2])
+
+# Step 1: Fingerprint
+fp1 = create_fingerprint(cat1)
+# โ "happypaws_persian_adult_female"
+fp2 = create_fingerprint(cat2)
+# โ "happypaws_persian_adult_female"
+# โ MATCH! Likely duplicate
+
+# Step 2: Text similarity
+name_sim = calculate_levenshtein_similarity(
+ "Fluffy",
+ "Fluffy (Happy Paws)"
+)
+# โ 0.73
+
+desc_sim = calculate_levenshtein_similarity(
+ "Friendly lap cat who loves cuddles",
+ "Sweet lap cat, loves to cuddle"
+)
+# โ 0.82
+
+# Step 3: Image similarity
+embed1 = get_image_embedding(cat1.primary_photo)
+embed2 = get_image_embedding(cat2.primary_photo)
+img_sim = cosine_similarity(embed1, embed2)
+# โ 0.94 (very similar - probably same photo)
+
+# Step 4: Composite score
+score = calculate_composite_score(
+ name_similarity=0.73,
+ description_similarity=0.82,
+ image_similarity=0.94
+)
+# โ 0.82 (82% - above 75% threshold)
+
+# Step 5: Mark as duplicate
+db.mark_as_duplicate(
+ duplicate_id="rescuegroups_67890",
+ original_id="petfinder_12345"
+)
+
+# Result: Only cat1 returned to user
+```
+
+**Result**: User sees Fluffy once, not twice.

+4. **API Fetching** โ `petfinder_agent.py:search_cats()` + `rescuegroups_agent.py:search_cats()`
+5. **Deduplication** โ `deduplication_agent.py:deduplicate()`
+6. **Caching** โ `manager.py:cache_cat()`
+7. **Embedding** โ `setup_vectordb.py:add_cats()`
+8. **Matching** โ `matching_agent.py:search()`
+9. **Display** โ `app.py:build_results_grid()`
+
+### Cross-Cutting Functionality
+
+**Logging**: Every agent uses `agent.py:log()` with color coding
+
+**Rate Limiting**: `petfinder_agent.py:_rate_limit()` and `rescuegroups_agent.py:_rate_limit()`
+
+**Error Handling**: Try/except blocks at agent level, graceful degradation
+
+**Caching**: Two-level (SQLite + ChromaDB) for speed and quality
+
+**Timing**: `@timed` decorator tracks performance

+
+### Key Design Patterns
+
+- **Agent Pattern**: Specialized agents for different tasks
+- **Orchestrator Pattern**: Planning agent coordinates workflow
+- **Repository Pattern**: DatabaseManager abstracts data access
+- **Strategy Pattern**: Different search strategies (Petfinder, RescueGroups)
+- **Decorator Pattern**: Rate limiting and timing decorators
+- **Observer Pattern**: Scheduled jobs watch for new alerts
+
+### Technology Stack
+
+**Frontend**: Gradio
+**Backend**: Python 3.12
+**Framework**: Custom Agent-based
+**Databases**: SQLite, ChromaDB
+**AI/ML**: OpenAI GPT-4, CLIP, SentenceTransformers
+**Deployment**: Modal (Serverless)
+**APIs**: Petfinder, RescueGroups, SendGrid

+- Whitespace handling
+- All dictionary mappings validation
+
+---
+
+## Integration Tests (11 tests โ )
+
+Integration tests validate end-to-end workflows.
+
+### Test Search Pipeline
+```bash
+pytest tests/integration/test_search_pipeline.py -v
+```
+
+**Tests**:
+- Complete search flow (API โ dedup โ cache โ match โ results)
+- Cache mode functionality
+- Deduplication integration
+- Hybrid matching
+- API failure handling
+- Vector DB updates
+- Statistics tracking
+
+### Test Alerts System
+```bash
+pytest tests/integration/test_alerts.py -v
+```
+
+**Tests**:
+- Alert creation and retrieval
+- Email-based alert queries
+- Alert updates (frequency, status)
+- Alert deletion
+- Immediate notifications (production mode)
+- Local vs production behavior
+- UI integration
+
+### Test App Functionality
+```bash
+pytest tests/integration/test_app.py -v
+```
+
+**Tests**:
+- Profile extraction from UI
+- Search result formatting
+- Alert management UI
+- Email validation
+- Error handling
+
+### Test Color and Breed Normalization
+```bash
+pytest tests/integration/test_color_breed_normalization.py -v
+```
+
+**Tests**:
+- Tuxedo color normalization in search flow
+- Multiple colors normalization
+- Breed normalization (Maine Coon typo handling)
+- Fuzzy matching with vector DB
+- Combined colors and breeds in search
+- RescueGroups API normalization
+- Empty preferences handling
+- Invalid color/breed graceful handling
+
+---
+
+## Manual Test Scripts
+
+These scripts are for manual testing with real APIs and data.
+
+### Test Cache and Deduplication
+```bash
+python tests/manual/test_cache_and_dedup.py
+```
+
+**Purpose**: Verify cache mode and deduplication with real data
+
+**What it does**:
+1. Runs a search without cache (fetches from APIs)
+2. Displays statistics (cats found, duplicates removed, cache size)
+3. Runs same search with cache (uses cached data)
+4. Compares performance and results
+5. Shows image embedding deduplication in action
+
+### Test Email Sending
+```bash
+python tests/manual/test_email_sending.py
+```
+
+**Purpose**: Send test emails via configured provider
+
+**What it does**:
+1. Sends welcome email
+2. Sends match notification email with sample data
+3. Verifies HTML rendering and provider integration
+
+**Requirements**: Valid MAILGUN_API_KEY or SENDGRID_API_KEY in `.env`
+
+### Test Semantic Color/Breed Matching
+```bash
+python scripts/test_semantic_matching.py
+```
+
+**Purpose**: Verify 3-tier color and breed matching system
+
+**What it does**:
+1. Tests color mapping with and without vector DB
+2. Tests breed mapping with and without vector DB
+3. Demonstrates typo handling ("tuxado" โ "tuxedo", "ragdol" โ "Ragdoll")
+4. Shows dictionary vs vector vs fallback matching
+5. Displays similarity scores for fuzzy matches
+
+**What you'll see**:
+- โ Dictionary matches (instant)
+- โ Vector DB fuzzy matches (with similarity scores)
+- โ Typo correction in action
+- โ 3-tier strategy demonstration
+
+### Test Framework Directly
+```bash
+python cat_adoption_framework.py
+```
+
+**Purpose**: Run framework end-to-end test
+
+**What it does**:
+1. Initializes framework
+2. Creates sample profile
+3. Executes search
+4. Displays top matches
+5. Shows statistics
+
+---
+
+## Test Configuration
+
+### Fixtures
+
+Common test fixtures are defined in `tests/conftest.py`:
+
+- `temp_db` - Temporary database for testing
+- `temp_vectordb` - Temporary vector store
+- `sample_cat` - Sample cat object
+- `sample_profile` - Sample search profile
+- `mock_framework` - Mocked framework for unit tests
+
+### Environment
+
+Tests use separate databases to avoid affecting production data:
+- `test_tuxedo_link.db` - Test database (auto-deleted)
+- `test_vectorstore` - Test vector store (auto-deleted)
+
+### Mocking
+
+External APIs are mocked in unit tests:
+- Petfinder API calls
+- RescueGroups API calls
+- Email provider calls
+- Modal remote functions
+
+Integration tests can use real APIs (set `SKIP_API_TESTS=false` in environment).

- ## In Loving Memory of Kyra ๐ฑ
-
- This application is dedicated to **Kyra**, a beloved companion who brought joy,
- comfort, and unconditional love to our lives. Kyra was more than just a catโ
- he was family, a friend, and a constant source of happiness.
-
- ### The Inspiration
-
- Kyra Link was created to help others find their perfect feline companion,
- just as Kyra found his way into our hearts. Every cat deserves a loving home,
- and every person deserves the companionship of a wonderful cat like Kyra.
-
- ### The Technology
-
- This application uses AI and machine learning to match prospective
- adopters with their ideal cat:
-
- - **Natural Language Processing**: Understand your preferences in plain English
- - **Semantic Search**: Find cats based on personality, not just keywords
- - **Multi-Source Aggregation**: Search across multiple adoption platforms
- - **Smart Deduplication**: Remove duplicate listings using AI
- - **Image Recognition**: Match cats visually using computer vision
- - **Hybrid Matching**: Combine semantic understanding with structured filters
-
- ### Features
-
- โ **Multi-Platform Search**: Petfinder, RescueGroups
- โ **AI-Powered Matching**: Semantic search with vector embeddings
- โ **Smart Deduplication**: Name, description, and image similarity
- โ **Personality Matching**: Find cats that match your lifestyle
- โ **Location-Based**: Search near you with customizable radius
-
- ### Technical Stack
-
- - **Frontend**: Gradio
- - **Backend**: Python with Modal serverless
- - **LLMs**: OpenAI GPT-4 for profile extraction
- - **Vector DB**: ChromaDB with SentenceTransformers
- - **Image AI**: CLIP for visual similarity
- - **APIs**: Petfinder, RescueGroups, SendGrid
- - **Database**: SQLite for caching and user management
-
- ### Open Source
-
- Tuxedo Link is open source and built as part of the Andela LLM Engineering bootcamp.
- Contributions and improvements are welcome!
-
- ### Acknowledgments
-
- - **Petfinder**: For their comprehensive pet adoption API
- - **RescueGroups**: For connecting rescues with adopters
- - **Andela**: For the LLM Engineering bootcamp
- - **Kyra**: For inspiring this project and bringing so much joy ๐

-## ๐ Modal Deployment Guide
-
-How to deploy Tuxedo Link to Modal for production use.
-
----
-
-## ๐๏ธ Production Architecture
-
-In production mode, Tuxedo Link uses a **hybrid architecture**:
-
-### Component Distribution
-
-**Local (Your Computer)**:
-- Gradio UI (`app.py`) - User interface only
-- No heavy ML models loaded
-- Fast startup
-
-**Modal (Cloud)**:
-- `modal_api.py` - Main API functions (profile extraction, search, alerts)
-- `scheduled_search.py` - Scheduled jobs (daily/weekly alerts, cleanup)
-- Database (SQLite on Modal volume)
-- Vector DB (ChromaDB on Modal volume)
-- All ML models (GPT-4, SentenceTransformer, CLIP)
-
-### Communication Flow
-
-```
-User โ Gradio UI (local) โ modal.Function.from_name().remote() โ Modal API โ Response โ UI
-```
-
-**Key Functions Exposed by Modal**:
-1. `extract_profile` - Convert natural language to CatProfile
-2. `search_cats` - Execute complete search pipeline
-3. `create_alert_and_notify` - Create alert with optional immediate email
-4. `get_alerts` / `update_alert` / `delete_alert` - Alert management
-
----
-
-## ๐ Quick Start (Automated Deployment)
-
-The easiest way to deploy is using the automated deployment script:
-
-```bash
-cd week8/community_contributions/dkisselev-zz/tuxedo_link
-
-# 1. Configure config.yaml for production
-cp config.example.yaml config.yaml
-# Edit config.yaml and set deployment.mode to 'production'
-
-# 2. Ensure environment variables are set
-# Load from .env or set manually:
-export OPENAI_API_KEY=sk-...
-export PETFINDER_API_KEY=...
-export PETFINDER_SECRET=...
-export RESCUEGROUPS_API_KEY=...
-export MAILGUN_API_KEY=...
-
-# 3. Run deployment script
-./deploy.sh
-```
-
-The script will automatically:
-- โ Validate Modal authentication
-- โ Check configuration
-- โ Create/update Modal secrets
-- โ Create Modal volume
-- โ Upload config.yaml to Modal
-- โ Deploy scheduled search services

-## Configuration System
-
-**File**: `utils/config.py`
-**Purpose**: Centralized YAML-based configuration management with environment variable overrides
-
-### Overview
-
-The configuration system separates API keys (in `.env`) from application settings (in `config.yaml`), enabling:
-- Deployment mode switching (local vs production)
-- Email provider selection
-- Database path configuration
-- Easy configuration without code changes
-
-### Core Functions
-
-#### 1. `load_config()`
-
-**Purpose**: Load and cache configuration from YAML file.
-
-**Signature**:
-```python
-def load_config() -> Dict[str, Any]
-```
-
-**Returns**: Complete configuration dictionary
-
-**Behavior**:
-- First checks for `config.yaml`
-- Falls back to `config.example.yaml` if not found
-- Applies environment variable overrides
-- Caches result for performance
-
-**Example**:
-```python
-config = load_config()
-# Returns:
-# {
-# 'email': {'provider': 'mailgun', ...},
-# 'deployment': {'mode': 'local', ...},
-# ...
-# }
-```
-
-#### 2. `is_production()`
-
-**Purpose**: Check if running in production mode.
-
-**Signature**:
-```python
-def is_production() -> bool
-```
-
-**Returns**: `True` if `deployment.mode == 'production'`, else `False`
-
-**Usage**:
-```python
-if is_production():
- # Use Modal remote functions
- send_immediate_notification.remote(alert_id)
-else:
- # Local mode - can't send immediate notifications
- print("Immediate notifications only available in production")
-```
-
-#### 3. `get_db_path()` / `get_vectordb_path()`
-
-**Purpose**: Get database paths based on deployment mode.
-
-**Signature**:
-```python
-def get_db_path() -> str
-def get_vectordb_path() -> str
-```
-
-**Returns**:
-- Local mode: `"data/tuxedo_link.db"`, `"cat_vectorstore"`
-- Production mode: `"/data/tuxedo_link.db"`, `"/data/cat_vectorstore"`
-
-**Example**:
-```python
-db_path = get_db_path() # Automatically correct for current mode
-db_manager = DatabaseManager(db_path)
-```
-
-#### 4. `get_email_provider()` / `get_email_config()` / `get_mailgun_config()`
-
-**Purpose**: Get email-related configuration.
-
-**Signatures**:
-```python
-def get_email_provider() -> str # Returns "mailgun" or "sendgrid"
-def get_email_config() -> Dict[str, str] # Returns from_name, from_email
-def get_mailgun_config() -> Dict[str, str] # Returns domain
-```
-
-**Example**:
-```python
-provider_name = get_email_provider() # "mailgun"
-email_cfg = get_email_config()
-# {'from_name': 'Tuxedo Link', 'from_email': 'noreply@...'}
-```
-
-### Configuration File Structure
-
-**`config.yaml`**:
-```yaml
-email:
- provider: mailgun
- from_name: "Tuxedo Link"
- from_email: "noreply@example.com"
-
-mailgun:
- domain: "sandbox123.mailgun.org"
-
-deployment:
- mode: local # or production
- local:
- db_path: "data/tuxedo_link.db"
- vectordb_path: "cat_vectorstore"
- production:
- db_path: "/data/tuxedo_link.db"
- vectordb_path: "/data/cat_vectorstore"
-```
-
-### Environment Overrides
-
-Environment variables can override config:
-```bash
-export EMAIL_PROVIDER=sendgrid # Overrides config.yaml
-export DEPLOYMENT_MODE=production
-```
-
----
-
-## Email Provider System
-
-**Files**: `agents/email_providers/*.py`
-**Purpose**: Pluggable email backend system supporting multiple providers
-
-### Architecture
-
-```
-EmailAgent
- โ
-get_email_provider() [factory.py]
- โ
-โโโ MailgunProvider [mailgun_provider.py]
-โโโ SendGridProvider [sendgrid_provider.py] (stub)
- โ
-send_email() via requests or API
-```
-
-### Core Components
-
-#### 1. `EmailProvider` (Base Class)
-
-**File**: `agents/email_providers/base.py`
-
-**Purpose**: Abstract interface all providers must implement.
-
-**Methods**:
-```python
-class EmailProvider(ABC):
- @abstractmethod
- def send_email(
- self,
- to: str,
- subject: str,
- html: str,
- text: str,
- from_email: Optional[str] = None,
- from_name: Optional[str] = None
- ) -> bool:
- pass
-
- @abstractmethod
- def get_provider_name(self) -> str:
- pass
-```
-
-#### 2. `MailgunProvider`
-
-**File**: `agents/email_providers/mailgun_provider.py`
-
-**Purpose**: Full Mailgun API implementation using requests library.
-
-**Initialization**:
-```python
-provider = MailgunProvider()
-# Reads:
-# - MAILGUN_API_KEY from environment
-# - mailgun.domain from config.yaml
-# - email.from_name, email.from_email from config.yaml
-```
-
-**Key Methods**:
-
-**`send_email()`**:
-```python
-def send_email(
- to: str,
- subject: str,
- html: str,
- text: str,
- from_email: Optional[str] = None,
- from_name: Optional[str] = None
-) -> bool
-```
-
-**Example**:
-```python
-provider = MailgunProvider()
-success = provider.send_email(
- to="user@example.com",
- subject="New Cat Matches!",
- html="
Found 5 matches
...",
- text="Found 5 matches..."
-)
-# Returns: True if sent, False if failed
-```
-
-**Implementation Details**:
-- Uses `requests.post()` with `auth=("api", api_key)`
-- Sends to `https://api.mailgun.net/v3/{domain}/messages`
-- Returns `True` on status 200, `False` otherwise
-- Logs all operations for debugging
-
-#### 3. `SendGridProvider` (Stub)
-
-**File**: `agents/email_providers/sendgrid_provider.py`
-
-**Purpose**: Stub implementation for testing/backwards compatibility.
-
-**Behavior**:
-- Always returns `True` (simulates success)
-- Logs what would be sent (doesn't actually send)
-- Useful for testing without API calls
-
-**Example**:
-```python
-provider = SendGridProvider()
-success = provider.send_email(...) # Always True
-# Logs: "[STUB] Would send email via SendGrid to user@example.com"
-```
-
-#### 4. `get_email_provider()` (Factory)
-
-**File**: `agents/email_providers/factory.py`
-
-**Purpose**: Create provider instance based on configuration.
-
-**Signature**:
-```python
-def get_email_provider(provider_name: Optional[str] = None) -> EmailProvider
-```
-
-**Parameters**:
-- `provider_name`: Optional override (default: reads from config)
-
-**Returns**: Configured provider instance
-
-**Example**:
-```python
-# Use configured provider
-provider = get_email_provider() # Reads config.yaml
-
-# Or specify explicitly
-provider = get_email_provider('mailgun')
-provider = get_email_provider('sendgrid')
-```
-
-### Integration with EmailAgent
-
-**File**: `agents/email_agent.py`
-
-**Modified** to use provider system:
-```python
-class EmailAgent(Agent):
- def __init__(self, provider: Optional[EmailProvider] = None):
- self.provider = provider or get_email_provider()
- self.enabled = True if self.provider else False
-
- def send_match_notification(self, alert, matches):
- # Build HTML/text templates
- html = self._build_match_html(matches, alert)
- text = self._build_match_text(matches)
-
- # Send via provider
- success = self.provider.send_email(
- to=alert.user_email,
- subject=f"๐ฑ {len(matches)} New Cat Matches!",
- html=html,
- text=text
- )
- return success
-```
-
-## Semantic Color/Breed Matching
-
-**NEW in v2.1** - 3-tier intelligent normalization system for color and breed terms.
-
-### Overview
-
-The semantic matching system ensures user queries like "find me a tuxedo maine coon" are correctly translated to API values, even with typos ("tuxado", "main coon"). It uses a **3-tier strategy**:
-
-1. **Dictionary Lookup** (< 1ms) - Common terms mapped instantly
-2. **Vector DB Search** (10-50ms) - Fuzzy matching for typos
-3. **String Matching** (< 1ms) - Fallback for edge cases
-
-### Architecture
-
-```
-User Input โ Profile Agent โ Planning Agent โ API Call
- โ (extract) โ (normalize)
- "tuxedo" 1. Dictionary โ "Black & White / Tuxedo"
- 2. Vector DB โ (if not found)
- 3. Fallback โ (if still not found)
-```
-
-### Components
-
-#### 1. Metadata Vector Database (`setup_metadata_vectordb.py`)
-
-Separate ChromaDB for color/breed fuzzy matching.
-
-**Class**: `MetadataVectorDB`
-
-**Initialization**:
-```python
-from setup_metadata_vectordb import MetadataVectorDB
-
-vectordb = MetadataVectorDB("metadata_vectorstore")
-```
-
-**Key Methods**:
-
-##### `index_colors(valid_colors: List[str], source: str)`
-
-Indexes color values from an API.
-
-```python
-colors = ["Black", "White", "Black & White / Tuxedo"]
-vectordb.index_colors(colors, source="petfinder")
-```
-
-##### `index_breeds(valid_breeds: List[str], source: str)`
-
-Indexes breed values from an API.
-
-```python
-breeds = ["Siamese", "Maine Coon", "Ragdoll"]
-vectordb.index_breeds(breeds, source="petfinder")
-```
-
-##### `search_color(user_term: str, n_results: int = 1, source_filter: Optional[str] = None)`
-
-Find most similar color via semantic search.
-
-**Returns**: `List[Dict]` with keys: `color`, `distance`, `similarity`, `source`
-
-```python
-results = vectordb.search_color("tuxado", n_results=1)
-# [{"color": "Black & White / Tuxedo", "similarity": 0.85, "source": "petfinder"}]
-```
-
-##### `search_breed(user_term: str, n_results: int = 1, source_filter: Optional[str] = None)`
-
-Find most similar breed via semantic search.
-
-```python
-results = vectordb.search_breed("ragdol", n_results=1)
-# [{"breed": "Ragdoll", "similarity": 0.92, "source": "petfinder"}]
-```
-
-##### `get_stats()`
-
-Get statistics about indexed data.
-
-```python
-stats = vectordb.get_stats()
-# {"colors_count": 48, "breeds_count": 102}
-```
-
----
-
-#### 2. Color Mapping (`utils/color_mapping.py`)
-
-Normalizes user color terms to valid API values.
-
-**Dictionary**: `USER_TERM_TO_API_COLOR` - 40+ mappings
-
-**Key examples**:
-- `"tuxedo"` โ `["Black & White / Tuxedo"]`
-- `"orange tabby"` โ `["Tabby (Orange / Red)"]`
-- `"gray"` / `"grey"` โ `["Gray / Blue / Silver"]`
-
-##### `normalize_user_colors(user_colors, valid_api_colors, vectordb=None, source="petfinder", similarity_threshold=0.7)`
-
-3-tier normalization for colors.
-
-**Parameters**:
-- `user_colors`: List of user color terms
-- `valid_api_colors`: Valid colors from API
-- `vectordb`: Optional MetadataVectorDB for fuzzy matching
-- `source`: API source filter ("petfinder"/"rescuegroups")
-- `similarity_threshold`: Minimum similarity (0-1) for vector matches
-
-**Returns**: `List[str]` - Valid API color values
-
-**Example**:
-```python
-from utils.color_mapping import normalize_user_colors
-
-valid_colors = ["Black", "White", "Black & White / Tuxedo"]
-
-# Tier 1: Dictionary
-result = normalize_user_colors(["tuxedo"], valid_colors)
-# ["Black & White / Tuxedo"]
-
-# Tier 2: Vector DB (with typo)
-result = normalize_user_colors(
- ["tuxado"], # Typo!
- valid_colors,
- vectordb=metadata_vectordb,
- source="petfinder",
- similarity_threshold=0.6
-)
-# ["Black & White / Tuxedo"] (if similarity >= 0.6)
-
-# Tier 3: Fallback
-result = normalize_user_colors(["Black"], valid_colors)
-# ["Black"] (exact match)
-```
-
-**Logging**:
-```
-๐ฏ Dictionary match: 'tuxedo' โ ['Black & White / Tuxedo']
-๐ Vector match: 'tuxado' โ 'Black & White / Tuxedo' (similarity: 0.85)

-
-#### 4. Agent Integration
-
-##### PetfinderAgent
-
-**New Methods**:
-
-###### `get_valid_colors() -> List[str]`
-
-Fetch all valid cat colors from Petfinder API (`/v2/types/cat`).
-
-**Returns**: 30 colors (cached)
-
-```python
-agent = PetfinderAgent()
-colors = agent.get_valid_colors()
-# ["Black", "Black & White / Tuxedo", "Blue Cream", ...]
-```
-
-###### `get_valid_breeds() -> List[str]`
-
-Fetch all valid cat breeds from Petfinder API (`/v2/types/cat/breeds`).
-
-**Returns**: 68 breeds (cached)
-
-```python
-breeds = agent.get_valid_breeds()
-# ["Abyssinian", "American Curl", "American Shorthair", ...]
-```
-
-###### `search_cats(..., color: Optional[List[str]], breed: Optional[List[str]], ...)`
-
-Search with **normalized** color and breed values.
-
-```python
-# User says "tuxedo maine coon"
-# Planning agent normalizes:
-# - "tuxedo" โ ["Black & White / Tuxedo"]
-# - "maine coon" โ ["Maine Coon"]
-
-results = agent.search_cats(
- location="NYC",
- color=["Black & White / Tuxedo"], # Normalized!
- breed=["Maine Coon"], # Normalized!
- limit=100
-)
-```
-
----

-```
-
-###### `get_valid_breeds() -> List[str]`
-
-Fetch all valid cat breeds from RescueGroups API (`/v5/public/animals/breeds`).
-
-**Returns**: 807 breeds (cached)
-
-```python

-
-**Note**: RescueGroups API doesn't support direct color/breed filtering. Values are logged but filtered client-side.
-
-```python
-results = agent.search_cats(
- location="NYC",
- color=["Tuxedo"], # Logged, filtered client-side
- breed=["Maine Coon"] # Logged, filtered client-side
-)
-```
-
----
-
-##### PlanningAgent
-
-**Modified Methods**:

-
-```python
-# User profile
-profile = CatProfile(
- color_preferences=["tuxedo", "orange tabby"],
- preferred_breeds=["main coon", "ragdol"] # Typos!
-)
-
-# Planning agent normalizes:
-# 1. Fetches valid colors/breeds from API
-# 2. Runs 3-tier normalization
-# 3. Passes normalized values to API
-
-# Logs:
-# โ Colors: ['tuxedo', 'orange tabby'] โ ['Black & White / Tuxedo', 'Tabby (Orange / Red)']
-# โ Breeds: ['main coon', 'ragdol'] โ ['Maine Coon', 'Ragdoll']
-```
-
----
-
-#### 5. Framework Integration
-
-##### TuxedoLinkFramework
-
-**New Initialization Step**: `_index_metadata()`
-
-Called during framework initialization to populate metadata vector DB.
-
-```python
-def _index_metadata(self):
- """Index colors and breeds from APIs."""
-
- # Fetch and index Petfinder
- petfinder = PetfinderAgent()
- colors = petfinder.get_valid_colors() # 30 colors
- breeds = petfinder.get_valid_breeds() # 68 breeds
- self.metadata_vectordb.index_colors(colors, source="petfinder")
- self.metadata_vectordb.index_breeds(breeds, source="petfinder")
-
- # Fetch and index RescueGroups
- rescuegroups = RescueGroupsAgent()
- colors = rescuegroups.get_valid_colors() # 597 colors
- breeds = rescuegroups.get_valid_breeds() # 807 breeds
- self.metadata_vectordb.index_colors(colors, source="rescuegroups")
- self.metadata_vectordb.index_breeds(breeds, source="rescuegroups")
-
- # Log stats
- stats = self.metadata_vectordb.get_stats()
- # โ Metadata indexed: 48 colors, 102 breeds
-```
-
-**Performance**: ~2-5 seconds on first run, then cached.
-
----
-
-### Complete Flow Example
-
-```python
-from cat_adoption_framework import TuxedoLinkFramework
-from models.cats import CatProfile
-
-# 1. Initialize framework (auto-indexes metadata)
-framework = TuxedoLinkFramework()
-# [INFO] โ Fetched 30 valid colors from Petfinder
-# [INFO] โ Fetched 68 valid breeds from Petfinder
-# [INFO] โ Fetched 597 valid colors from RescueGroups
-# [INFO] โ Fetched 807 valid breeds from RescueGroups
-# [INFO] โ Metadata indexed: 48 colors, 102 breeds
-
-# 2. User searches with natural language (with typos!)
-profile = CatProfile(
- user_location="Boston, MA",
- color_preferences=["tuxado", "ornage tabby"], # Typos!
- preferred_breeds=["main coon", "ragdol"], # Typos!
- max_distance=50
-)
-
-# 3. Framework normalizes and searches
-result = framework.search(profile)
-
-# Behind the scenes:
-# [INFO] ๐ฏ Dictionary match: 'main coon' โ ['Maine Coon']
-# [INFO] ๐ฏ Dictionary match: 'ragdol' โ ['Ragdoll']
-# [INFO] ๐ Vector match: 'tuxado' โ 'Black & White / Tuxedo' (similarity: 0.85)
-# [INFO] ๐ Vector match: 'ornage tabby' โ 'Tabby (Orange / Red)' (similarity: 0.78)
-# [INFO] โ Colors: ['tuxado', 'ornage tabby'] โ ['Black & White / Tuxedo', 'Tabby (Orange / Red)']
-# [INFO] โ Breeds: ['main coon', 'ragdol'] โ ['Maine Coon', 'Ragdoll']
-
-# 4. APIs receive normalized values
-# Petfinder.search_cats(color=['Black & White / Tuxedo', 'Tabby (Orange / Red)'], breed=['Maine Coon', 'Ragdoll'])
-# RescueGroups.search_cats(color=['Black & White / Tuxedo', 'Tabby (Orange / Red)'], breed=['Maine Coon', 'Ragdoll'])
-
-# 5. Results returned
-print(f"Found {len(result.matches)} matches!")
-```
-
----
-
-### Configuration
-
-No configuration needed! The system:
-- โ Automatically fetches valid colors/breeds from APIs
-- โ Indexes them on startup (persisted to disk)
-- โ Uses 3-tier strategy transparently
-- โ Logs all normalization steps for debugging
-
-**Optional**: Adjust similarity threshold in planning agent:
-
-```python
-# In agents/planning_agent.py
-api_colors = normalize_user_colors(
- profile.color_preferences,
- valid_colors,
- vectordb=self.metadata_vectordb,
- source="petfinder",
- similarity_threshold=0.8 # Default: 0.7
-)
-```
-
----
-
-### Summary
-
-The semantic color/breed matching system provides:
-
-โ **Natural Language**: Users can use terms like "tuxedo", "orange tabby"
-โ **Typo Tolerance**: "tuxado" โ "tuxedo", "main coon" โ "Maine Coon"
-โ **3-Tier Strategy**: Dictionary โ Vector โ Fallback (99%+ coverage)
-โ **Fast**: < 50ms overhead per search
-โ **Automatic**: No configuration required
-โ **Multi-API**: Works with Petfinder & RescueGroups
-โ **Well-Tested**: 46 unit tests + 8 integration tests
-โ **Extensible**: Easy to add new mappings or APIs
-
-**Impact**: Users can now search naturally without needing to know exact API color/breed values, resulting in better search results and improved adoption rates! ๐ฑ

-# {
-# 'removed': 145,
-# 'kept': 250,
-# 'vector_db_size': 250
-# }
-```
-
----
-
-### Modal Image Configuration
-
-Both Modal files use a carefully configured image with compatible package versions:
-
-```python
-from pathlib import Path
-import modal
-
-project_dir = Path(__file__).parent
-
-image = (
- modal.Image.debian_slim(python_version="3.11")
- .pip_install(
- "openai",
- "chromadb",
- "requests",
- "sentence-transformers==2.5.1", # Compatible with torch 2.2.2
- "transformers==4.38.0", # Compatible with torch 2.2.2
- "Pillow",
- "python-dotenv",
- "pydantic",
- "geopy",
- "pyyaml",
- "python-levenshtein",
- "open-clip-torch==2.24.0", # Compatible with torch 2.2.2
- )
- .apt_install("git")
- .run_commands(
- "pip install torch==2.2.2 torchvision==0.17.2 --index-url https://download.pytorch.org/whl/cpu",
- "pip install numpy==1.26.4",
- )
- # Add only necessary source directories
- .add_local_dir(str(project_dir / "models"), remote_path="/root/models")
- .add_local_dir(str(project_dir / "agents"), remote_path="/root/agents")
- .add_local_dir(str(project_dir / "database"), remote_path="/root/database")
- .add_local_dir(str(project_dir / "utils"), remote_path="/root/utils")
- # Add standalone Python files
- .add_local_file(str(project_dir / "cat_adoption_framework.py"), remote_path="/root/cat_adoption_framework.py")
- .add_local_file(str(project_dir / "setup_vectordb.py"), remote_path="/root/setup_vectordb.py")
- .add_local_file(str(project_dir / "setup_metadata_vectordb.py"), remote_path="/root/setup_metadata_vectordb.py")
- # Add config file
- .add_local_file(str(project_dir / "config.yaml"), remote_path="/root/config.yaml")
-)
-```
-
-**Critical Points**:
-1. โ Modal files at project root for auto-discovery
-2. โ Top-level imports (not inside functions)
-3. โ Explicit `add_local_dir()` for each source directory
-4. โ Compatible package versions (torch 2.2.2, transformers 4.38.0, etc.)
-5. โ Only necessary files added (not `.venv`, `cat_vectorstore`, etc.)

-
-### UI Integration with Modal
-
-**File**: `app.py`
-
-The UI uses conditional logic based on `is_production()` to either call Modal or use local framework:
-
-```python
-from utils.config import is_production
-
-if not is_production():
- # LOCAL MODE: Import and initialize heavy components
- from cat_adoption_framework import TuxedoLinkFramework
- from agents.profile_agent import ProfileAgent
-
- framework = TuxedoLinkFramework()
- profile_agent = ProfileAgent()
- print("โ Running in LOCAL mode - using local components")
-else:
- # PRODUCTION MODE: Don't import heavy components - use Modal API
- print("โ Running in PRODUCTION mode - using Modal API")
-```
-
-**Search Flow in Production**:
-
-```python
-def extract_profile_from_text(user_input: str, use_cache: bool = False):
- if is_production():
- # PRODUCTION: Call Modal API
- import modal
-
- # Extract profile via Modal
- extract_profile_func = modal.Function.from_name("tuxedo-link-api", "extract_profile")
- profile_result = extract_profile_func.remote(user_input)
- profile = CatProfile(**profile_result["profile"])
-
- # Search via Modal
- search_cats_func = modal.Function.from_name("tuxedo-link-api", "search_cats")
- search_result = search_cats_func.remote(profile.model_dump(), use_cache=use_cache)
-
- # Reconstruct matches from Modal response
- current_matches = [
- CatMatch(
- cat=Cat(**m["cat"]),
- match_score=m["match_score"],
- vector_similarity=m["vector_similarity"],
- attribute_match_score=m["attribute_match_score"],
- explanation=m["explanation"],
- matching_attributes=m.get("matching_attributes", []),
- missing_attributes=m.get("missing_attributes", [])
- )
- for m in search_result["matches"]
- ]
- else:
- # LOCAL: Use local framework
- profile = profile_agent.extract_profile([{"role": "user", "content": user_input}])
- result = framework.search(profile, use_cache=use_cache)
- current_matches = result.matches
-
- # Rest of function same for both modes
- return chat_history, results_html, profile_json
-```
-
----
-

-## Complete User Journey Examples
-
-### Example 1: First-Time Search
-
-**User Action**: Types "friendly kitten in NYC, good with kids"
-
-**System Flow**:
-
-```python
-# 1. UI receives input
-user_text = "friendly kitten in NYC, good with kids"
-
-# 2. Convert to conversation format & extract profile
-profile_agent = ProfileAgent()
-conversation = [{"role": "user", "content": user_text}]
-profile = profile_agent.extract_profile(conversation)
-# โ OpenAI GPT-4 API call (with conversation format)
-# โ CatProfile(location="NYC", age_range=["kitten"], good_with_children=True)
-
-# 3. Execute search
-framework = TuxedoLinkFramework()
-result = framework.search(profile, use_cache=False)
-
-# 4. Planning agent orchestrates
-planner = PlanningAgent()
-
-# 4a. Fetch from APIs (parallel)
-petfinder_cats = PetfinderAgent().search_cats(
- location="NYC",
- age="kitten",
- good_with_children=True
-) # Returns 45 cats
-
-rescuegroups_cats = RescueGroupsAgent().search_cats(
- location="NYC",
- age="kitten"
-) # Returns 38 cats
-
-# Total: 83 cats
-
-# 4b. Deduplicate
-dedup_agent = DeduplicationAgent()
-unique_cats = dedup_agent.deduplicate(cats)
-# Finds 8 duplicates (same cat on both platforms)
-# Unique: 75 cats
-
-# 4c. Cache with embeddings
-for cat in unique_cats:
- db.cache_cat(cat, get_image_embedding(cat.primary_photo))
-
-# 4d. Add to vector DB
-vector_db.add_cats(unique_cats)
-
-# 4e. Match and rank
-matching_agent = MatchingAgent()
-matches = matching_agent.search(profile, top_k=20)
-
-# Vector search finds: 50 semantically similar
-# Metadata filter: 32 meet hard constraints
-# Hybrid scoring: Rank all 32
-# Return top 20
-
-# 5. Format and display
-html = build_results_grid(matches)
-
-# 6. Return to user (OpenAI messages format)
-return (
- chat_history=[
- {"role": "user", "content": "friendly kitten in NYC, good with kids"},
- {"role": "assistant", "content": "โ Got it! Searching for...\n\nโจ Found 20 cats!"}
- ],
- results_html=html,
- profile_display='{"user_location": "NYC", "age_range": ["kitten"], ...}'
-)
-```
-
-**Result**: User sees 20 cat cards with photos, match scores, and explanations.
-
-**Note**: Chat history now uses OpenAI messages format (Gradio `type="messages"`) instead of deprecated tuples format.
-
----
-
-### Example 2: Cached Search (Developer Mode)
-
-**User Action**: Same search with "Use Cache" enabled
-
-**System Flow**:
-
-```python
-# 1-2. Same as above (extract profile)
-
-# 3. Execute search with cache
-result = framework.search(profile, use_cache=True)
-
-# 4. Planning agent uses cache
-cats = db.get_all_cached_cats(exclude_duplicates=True)
-# Returns: 75 cats (from previous search)
-
-# Skip API calls, deduplication, caching
-
-# 4a. Match and rank (same as before)
-matches = matching_agent.search(profile, top_k=20)
-
-# 5-6. Same as above (format and display)
-```
-
-**Result**:
-- Much faster (0.2s vs 13s)
-- No API calls (preserves rate limits)
-- Same quality results
-
----
-
-### Example 3: Email Alert Flow
-
-**User Action**: Saves search as daily alert
-
-**Initial Setup**:
-```python
-# 1. User registers
-user_id = db.create_user(email="user@example.com", password_hash="...")
-
-# 2. User creates alert
-alert = AdoptionAlert(
- user_id=user_id,
- user_email="user@example.com",
- profile=CatProfile(...), # Their search preferences
- frequency="daily",
- active=True
-)
-alert_id = db.create_alert(alert)
-```
-
-**Daily Scheduled Job** (Modal, 9 AM):
-```python
-# Runs on Modal cloud
-run_scheduled_searches()
-
-# 1. Load alerts
-alerts = db.get_active_alerts()
-# Returns: [AdoptionAlert(...), ...]
-
-# 2. For user's alert
-alert = alerts[0] # user@example.com
-
-# 3. Run search
-result = framework.search(alert.profile)
-# Returns: 18 matches
-
-# 4. Filter new matches
-last_seen_ids = alert.last_match_ids # ["pf_1", "pf_2", ...]
-new_matches = [
- m for m in result.matches
- if m.cat.id not in last_seen_ids
-]
-# New matches: 3 cats
-
-# 5. Send email
-email_agent = EmailAgent()
-email_agent.send_match_notification(alert, new_matches)
-
-# Email content:
-# Subject: "Tuxedo Link: 3 New Cat Matches!"
-# Body:
-# - Cat 1: Fluffy (85% match)
-# [Photo]
-# Great personality match, loves children
-# [View Details โ]
-#
-# - Cat 2: Max (82% match)
-# ...
-
-# 6. Update alert
-db.update_alert(
- alert_id=alert.id,
- last_sent=datetime.now(),
- last_match_ids=[m.cat.id for m in new_matches]
-)
-```
-
-**Result**: User receives email with 3 new cats, won't see them again tomorrow.
-
----
-
-### Example 4: Deduplication in Action
-
-**Scenario**: Same cat listed on Petfinder AND RescueGroups
-
-**Cat on Petfinder**:
-```python
-cat1 = Cat(
- id="petfinder_12345",
- name="Fluffy",
- breed="Persian",
- age="adult",
- gender="female",
- organization_name="Happy Paws Rescue",
- description="Friendly lap cat who loves cuddles",
- primary_photo="https://petfinder.com/photos/cat1.jpg"
-)
-```
-
-**Same Cat on RescueGroups**:
-```python
-cat2 = Cat(
- id="rescuegroups_67890",
- name="Fluffy (Happy Paws)",
- breed="Persian",
- age="adult",
- gender="female",
- organization_name="Happy Paws Rescue",
- description="Sweet lap cat, loves to cuddle",
- primary_photo="https://rescuegroups.org/photos/cat2.jpg"
-)
-```
-
-**Deduplication Process**:
-```python
-dedup_agent = DeduplicationAgent(db)
-unique = dedup_agent.deduplicate([cat1, cat2])
-
-# Step 1: Fingerprint
-fp1 = create_fingerprint(cat1)
-# โ "happypaws_persian_adult_female"
-fp2 = create_fingerprint(cat2)
-# โ "happypaws_persian_adult_female"
-# โ MATCH! Likely duplicate
-
-# Step 2: Text similarity
-name_sim = calculate_levenshtein_similarity(
- "Fluffy",
- "Fluffy (Happy Paws)"
-)
-# โ 0.73
-
-desc_sim = calculate_levenshtein_similarity(
- "Friendly lap cat who loves cuddles",
- "Sweet lap cat, loves to cuddle"
-)
-# โ 0.82
-
-# Step 3: Image similarity
-embed1 = get_image_embedding(cat1.primary_photo)
-embed2 = get_image_embedding(cat2.primary_photo)
-img_sim = cosine_similarity(embed1, embed2)
-# โ 0.94 (very similar - probably same photo)
-
-# Step 4: Composite score
-score = calculate_composite_score(
- name_similarity=0.73,
- description_similarity=0.82,
- image_similarity=0.94
-)
-# โ 0.82 (82% - above 75% threshold)
-
-# Step 5: Mark as duplicate
-db.mark_as_duplicate(
- duplicate_id="rescuegroups_67890",
- original_id="petfinder_12345"
-)
-
-# Result: Only cat1 returned to user
-```
-
-**Result**: User sees Fluffy once, not twice.

-4. **API Fetching** โ `petfinder_agent.py:search_cats()` + `rescuegroups_agent.py:search_cats()`
-5. **Deduplication** โ `deduplication_agent.py:deduplicate()`
-6. **Caching** โ `manager.py:cache_cat()`
-7. **Embedding** โ `setup_vectordb.py:add_cats()`
-8. **Matching** โ `matching_agent.py:search()`
-9. **Display** โ `app.py:build_results_grid()`
-
-### Cross-Cutting Functionality
-
-**Logging**: Every agent uses `agent.py:log()` with color coding
-
-**Rate Limiting**: `petfinder_agent.py:_rate_limit()` and `rescuegroups_agent.py:_rate_limit()`
-
-**Error Handling**: Try/except blocks at agent level, graceful degradation

-### Key Design Patterns
-
-- **Agent Pattern**: Specialized agents for different tasks
-- **Orchestrator Pattern**: Planning agent coordinates workflow
-- **Repository Pattern**: DatabaseManager abstracts data access
-- **Strategy Pattern**: Different search strategies (Petfinder, RescueGroups)
-- **Decorator Pattern**: Rate limiting and timing decorators
-- **Observer Pattern**: Scheduled jobs watch for new alerts
-
-### Technology Stack
-
-**Frontend**: Gradio
-**Backend**: Python 3.12
-**Framework**: Custom Agent-based
-**Databases**: SQLite, ChromaDB
-**AI/ML**: OpenAI GPT-4, CLIP, SentenceTransformers
-**Deployment**: Modal (Serverless)
-**APIs**: Petfinder, RescueGroups, SendGrid

-## Manual Test Scripts
-
-These scripts are for manual testing with real APIs and data.
-
-### Test Cache and Deduplication
-```bash
-python tests/manual/test_cache_and_dedup.py
-```
-
-**Purpose**: Verify cache mode and deduplication with real data
-
-**What it does**:
-1. Runs a search without cache (fetches from APIs)
-2. Displays statistics (cats found, duplicates removed, cache size)
-3. Runs same search with cache (uses cached data)
-4. Compares performance and results
-5. Shows image embedding deduplication in action
-
-### Test Email Sending
-```bash
-python tests/manual/test_email_sending.py
-```
-
-**Purpose**: Send test emails via configured provider
-
-**What it does**:
-1. Sends welcome email
-2. Sends match notification email with sample data
-3. Verifies HTML rendering and provider integration
-
-**Requirements**: Valid MAILGUN_API_KEY or SENDGRID_API_KEY in `.env`
-
-### Test Semantic Color/Breed Matching
-```bash
-python scripts/test_semantic_matching.py
-```
-
-**Purpose**: Verify 3-tier color and breed matching system
-
-**What it does**:
-1. Tests color mapping with and without vector DB
-2. Tests breed mapping with and without vector DB
-3. Demonstrates typo handling ("tuxado" โ "tuxedo", "ragdol" โ "Ragdoll")
-4. Shows dictionary vs vector vs fallback matching
-5. Displays similarity scores for fuzzy matches
-
-**What you'll see**:
-- โ Dictionary matches (instant)
-- โ Vector DB fuzzy matches (with similarity scores)
-- โ Typo correction in action
-- โ 3-tier strategy demonstration
-
-### Test Framework Directly
-```bash
-python cat_adoption_framework.py
-```
-
-**Purpose**: Run framework end-to-end test
-
-**What it does**:
-1. Initializes framework
-2. Creates sample profile
-3. Executes search
-4. Displays top matches
-5. Shows statistics
-
----
-
-## Test Configuration
-
-### Fixtures
-
-Common test fixtures are defined in `tests/conftest.py`:
-
-- `temp_db` - Temporary database for testing
-- `temp_vectordb` - Temporary vector store
-- `sample_cat` - Sample cat object
-- `sample_profile` - Sample search profile
-- `mock_framework` - Mocked framework for unit tests
-
-### Environment
-
-Tests use separate databases to avoid affecting production data:
-- `test_tuxedo_link.db` - Test database (auto-deleted)
-- `test_vectorstore` - Test vector store (auto-deleted)
-
-### Mocking
-
-External APIs are mocked in unit tests:
-- Petfinder API calls
-- RescueGroups API calls
-- Email provider calls
-- Modal remote functions
-
-Integration tests can use real APIs (set `SKIP_API_TESTS=false` in environment).
