+# Batch LLM Classifier - Quick Start
+
+## Prerequisite Check
+
+```bash
+python tools/batch_llm_classifier.py check
+```
+
+Expected: `✓ vLLM server is running and ready`
+
+If not running: Start vLLM server at rtx3090.bobai.com.au first
+
+---
+
+## Basic Usage
+
+```bash
+python tools/batch_llm_classifier.py ask \
+  --source enron \
+  --limit 50 \
+  --question "YOUR QUESTION HERE" \
+  --output results.txt
+```
+
+---
+
+## Example Questions
+
+### Find Urgent Emails
+```bash
+--question "Is this email urgent or time-sensitive? Answer yes/no and explain."
+```
+
+### Extract Financial Data
+```bash
+--question "List any dollar amounts, budgets, or financial numbers in this email."
+```
+
+### Meeting Detection
+```bash
+--question "Does this email mention a meeting? If yes, extract date/time/location."
+```
+
+### Sentiment Analysis
+```bash
+--question "What is the tone? Professional/Casual/Urgent/Frustrated? Explain."
+```
+
+### Custom Classification
+```bash
+--question "Should this email be archived or kept active? Why?"
+```
+
+---
+
+## Performance
+
+- **Throughput**: 4.65 requests/sec
+- **Batch size**: 4 (proper batch pooling)
+- **Reliability**: 100% success rate
+- **Example**: 500 requests in 108 seconds
+
+---
+
+## When To Use
+
+✅ **Use Batch LLM for:**
+- Custom questions on 50-500 emails
+- One-off exploratory analysis
+- Flexible classification criteria
+- Data extraction tasks
+
+❌ **Use RAG instead for:**
+- Searching 10k+ email corpus
+- Semantic topic search
+- Multi-document reasoning
+
+❌ **Use Main ML Pipeline for:**
+- Regular ongoing classification
+- High-volume processing (10k+ emails)
+- Consistent categories
+- Maximum speed
+
+---
+
+## Quick Test
+
+```bash
+# Check server
+python tools/batch_llm_classifier.py check
+
+# Process 10 emails
+python tools/batch_llm_classifier.py ask \
+  --source enron \
+  --limit 10 \
+  --question "Summarize this email in one sentence." \
+  --output test.txt
+
+# Check results
+cat test.txt
+```
+
+---
+
+## Files Created
+
+- `tools/batch_llm_classifier.py` - Main tool (executable)
+- `tools/README.md` - Full documentation
+- `test_llm_concurrent.py` - Performance testing script (root)
+
+**No files in `src/` were modified - existing ML pipeline untouched**
+
+---
+
+## Configuration
+
+Edit `VLLM_CONFIG` in `batch_llm_classifier.py`:
+
+```python
+VLLM_CONFIG = {
+    'base_url': 'https://rtx3090.bobai.com.au/v1',
+    'api_key': 'rtx3090_foxadmin_10_8034ecb47841f45ba1d5f3f5d875c092',
+    'model': 'qwen3-coder-30b',
+    'batch_size': 4,  # Don't increase - causes 503 errors
+}
+```
+
+---
+
+## Troubleshooting
+
+**Server not available:**
+```bash
+curl https://rtx3090.bobai.com.au/v1/models -H "Authorization: Bearer rtx3090_..."
+```
+
+**503 errors:**
+Lower `batch_size` to 2 in config (currently optimal is 4)
+
+**Slow processing:**
+Check vLLM server load - may be handling other requests
+
+---
+
+**Done!** Ready to ask custom questions across email batches.

+# Email Sorter - Development Guide
+
+## What This Tool Does
+
+**Email Sorter is a TRIAGE tool** that sorts emails into buckets for downstream processing. It is NOT a complete email management solution - it's one part of a larger ecosystem.
+
+```
+Raw Inbox (10k+) --> Email Sorter --> Categorized Buckets --> Specialized Tools
+                    (this tool)     (output)               (other tools)
+```
+
+---
+
+## Quick Start
+
+```bash
+cd /MASTERFOLDER/Tools/email-sorter
+source venv/bin/activate
+
+# Classify emails with ML + LLM fallback
+python -m src.cli run --source local \
+  --directory "/path/to/emails" \
+  --output "/path/to/output" \
+  --force-ml --llm-provider openai
+
+# Generate HTML report from results
+python tools/generate_html_report.py --input /path/to/results.json
+```

+
+---
+
+## Common Operations
+
+### 1. Classify Emails (ML Pipeline)
+
+```bash
+source venv/bin/activate
+
+# With LLM fallback for low confidence
+python -m src.cli run --source local \
+  --directory "/path/to/emails" \
+  --output "/path/to/output" \
+  --force-ml --llm-provider openai
+
+# Pure ML (fastest, no LLM)
+python -m src.cli run --source local \
+  --directory "/path/to/emails" \
+  --output "/path/to/output" \
+  --force-ml --no-llm-fallback
+```
+
+### 2. Generate HTML Report
+
+```bash
+python tools/generate_html_report.py --input /path/to/results.json
+# Creates report.html in same directory
+```
+
+### 3. Manual Agent Analysis (Best Accuracy)
+
+For <1000 emails, agent analysis gives 98-99% accuracy:
+
+```bash
+# Copy and customize analyzer template
+cp tools/brett_gmail_analyzer.py tools/my_inbox_analyzer.py
+
+# Edit classify_email() function for your inbox patterns
+# Update email_dir path
+# Run
+python tools/my_inbox_analyzer.py
+```
+
+### 4. Different Email Sources
+
+```bash
+# Local .eml/.msg files
+--source local --directory "/path/to/emails"
+
+# Gmail (OAuth)
+--source gmail --credentials credentials/gmail/account1.json
+
+# Outlook (OAuth)
+--source outlook --credentials credentials/outlook/account1.json
+
+# Enron test data
+--source enron --limit 10000
+```

+
+## Configuration
+
+### LLM Endpoint (config/default_config.yaml)
+
+```yaml
+llm:
+  provider: "openai"
+  openai:
+    base_url: "http://localhost:11433/v1"  # vLLM endpoint
+    api_key: "not-needed"
+    classification_model: "qwen3-coder-30b"
+```
+
+### Thresholds (config/categories.yaml)
+
+Default: 0.55 (reduced from 0.75 for 40% less LLM fallback)
+
+---
+
+## Key Code Locations
+
+| Function | File |
+|----------|------|
+| CLI entry | `src/cli.py` |
+| ML classifier | `src/classification/ml_classifier.py` |
+| LLM classifier | `src/classification/llm_classifier.py` |
+| Feature extraction | `src/classification/feature_extractor.py` |
+| Email parsing | `src/calibration/local_file_parser.py` |
+| OpenAI-compat LLM | `src/llm/openai_compat.py` |
+
+---
+
+## Recent Changes (Nov 2025)
+
+1. **cli.py**: Added `--force-ml` flag, enriched results.json with metadata
+2. **openai_compat.py**: Removed API key requirement for local vLLM
+3. **default_config.yaml**: Changed to openai provider on localhost:11433
+4. **tools/**: Added brett_gmail_analyzer.py, brett_microsoft_analyzer.py, generate_html_report.py
+5. **docs/**: Added PROJECT_ROADMAP_2025.md, CLASSIFICATION_METHODS_COMPARISON.md
+
+---
+
+## Troubleshooting
+
+### "LLM endpoint not responding"
+- Check vLLM running on localhost:11433
+- Verify model name in config matches running model
+
+### "Low accuracy (50-60%)"
+- For <1000 emails, use agent analysis
+- Dataset may differ from Enron training data
+
+### "Too many LLM calls"
+- Use `--no-llm-fallback` for pure ML
+- Increase threshold in categories.yaml
+
+---
+
+## Development Notes
+
+### Virtual Environment Required
+```bash
+source venv/bin/activate
+# ALWAYS activate before Python commands
+```
+
+### Batched Feature Extraction (CRITICAL)
+```python
+# CORRECT - Batched (150x faster)
+all_features = feature_extractor.extract_batch(emails, batch_size=512)
+
+# WRONG - Sequential (extremely slow)
+for email in emails:
+    result = classifier.classify(email)  # Don't do this
+```
+
+### Model Paths
+- `src/models/calibrated/` - Created during calibration
+- `src/models/pretrained/` - Loaded by default
+
+---
+
+## What's Gitignored
+
+- `credentials/` - OAuth tokens
+- `results/`, `data/` - User data
+- `archive/`, `docs/archive/` - Historical content
+- `maildir/` - Enron test data (large)
+- `enron_mail_20150507.tar.gz` - Source archive
+- `venv/` - Python environment
+- `*.log`, `logs/` - Log files
+
+---
+
+## Philosophy
+
+1. **Triage, not management** - Sort into buckets for other tools
+2. **Risk-based accuracy** - High for personal, acceptable errors for junk
+3. **Speed matters** - 10k emails in <1 min
+4. **Inbox character matters** - Business vs personal = different approaches
+5. **Agent pre-scan adds value** - 10-15 min discovery improves everything

-
----
-
-## Real Model Integration
-
-### Quick Start: Using Pre-trained Model
-
-```bash
-# Check if model is installed
-python tools/setup_real_model.py --check
-
-# Setup a pre-trained model (download or local file)
-python tools/setup_real_model.py --model-path /path/to/model.pkl
-
-# Create model info documentation
-python tools/setup_real_model.py --info
-```
-
-### Step 1: Get a Real Model
-
-**Option A: Train on Enron Dataset** (Recommended)
-```python
-from src.calibration.enron_parser import EnronParser
-from src.calibration.trainer import ModelTrainer
-from src.classification.feature_extractor import FeatureExtractor
-
-# Parse Enron
-parser = EnronParser("enron_mail_20150507")
-emails = parser.parse_emails(limit=5000)
-
-# Train model
-extractor = FeatureExtractor()
-trainer = ModelTrainer(extractor, categories=['junk', 'transactional', ...])
-results = trainer.train(labeled_data)
-
-# Save
-trainer.save_model("src/models/pretrained/classifier.pkl")
-```
-
-**Option B: Download Pre-trained**
-```bash
-python tools/download_pretrained_model.py \
-  --url https://example.com/model.pkl \
-  --hash abc123def456
-```
-
-### Step 2: Verify Integration
-
-```bash
-# Check model is loaded
-python -c "from src.classification.ml_classifier import MLClassifier; \
-  c = MLClassifier(); \
-  print(c.get_info())"
-
-# Should show: is_mock: False, model_type: LightGBM
-```
-
-### Step 3: Run Full Pipeline
-
-```bash
-# With real model (once set up)
-python -m src.cli run --source mock --output results/
-```

-## Feature Overview
-
-### Classification Accuracy
-- **Hard Rules**: 94-96% (instant, ~10% of emails)
-- **ML Model**: 85-90% (fast, ~85% of emails)
-- **LLM Review**: 92-95% (slower, ~5% uncertain)
-- **Overall**: 90-94% (weighted average)
-
-### Performance
-- **Calibration**: 3-5 minutes (1500 emails)
-- **Bulk Processing**: 10-12 minutes (80k emails)
-- **LLM Review**: 4-5 minutes (batched)
-- **Export**: 2-3 minutes
-- **Total**: ~17-25 minutes for 80k emails
-
-### Categories (12)
-junk, transactional, auth, newsletters, social, automated, conversational, work, personal, finance, travel, unknown
-
-### Features Extracted
-- **Semantic**: 384-dimensional embeddings (all-MiniLM-L6-v2)
-- **Patterns**: 20+ regex-based patterns
-- **Structural**: Metadata, timing, attachments, sender analysis
-
----
-
-## Known Issues & Limitations
-
-### Expected Test Failures (3/30 - Documented)
-
-**1. test_e2e_checkpoint_resume**
-- **Reason**: Feature vector mismatch when switching from mock to real model
-- **Impact**: Only relevant when upgrading models
-- **Resolution**: Not needed until real model deployed
-
-**2. test_e2e_enron_parsing**
-- **Reason**: EnronParser needs validation against actual maildir format
-- **Impact**: Parser works but needs dataset verification
-- **Resolution**: Will be validated during real training phase
-
-**3. test_pattern_detection_invoice**
-- **Reason**: Minor regex pattern doesn't match "bill #456"
-- **Impact**: Cosmetic - doesn't affect production accuracy
-- **Resolution**: Easy regex adjustment if needed
-
-### Pydantic Warnings (16 warnings)
-- **Reason**: Using deprecated `.dict()` method (Pydantic v2 compatibility)
-- **Severity**: Cosmetic - code still works perfectly
-- **Resolution**: Will migrate to `.model_dump()` in next update

-python -m src.cli run --source mock --output test_results/
-
-# Test with real model (when available)
-python -m src.cli run --source gmail --limit 100 --output results/
-```
-
-## How to Get a Real Model
-
-### Option 1: Train Your Own (Recommended)
-```python
-from src.calibration.trainer import ModelTrainer
-from src.calibration.enron_parser import EnronParser
-from src.classification.feature_extractor import FeatureExtractor
-
-# Parse Enron dataset
-parser = EnronParser("enron_mail_20150507")
-emails = parser.parse_emails(limit=5000)
-
-# Extract features
-extractor = FeatureExtractor()
-labeled_data = [(email, category) for email, category in zip(emails, categories)]
-
-# Train model
-trainer = ModelTrainer(extractor, categories)
-results = trainer.train(labeled_data)
-
-# Save model
-trainer.save_model("src/models/pretrained/classifier.pkl")
-```
-
-### Option 2: Download Pre-trained Model
-
-Use the provided script:
-```bash
-cd tools
-python download_pretrained_model.py \
-  --url https://example.com/model.pkl \
-  --hash abc123def456
-```
-
-### Option 3: Use Community Model
-
-Check available pre-trained models at:
-- Email Sorter releases on GitHub
-- Hugging Face model hub (when available)
-- Community-trained models
-
-## Model Performance
-
-Expected accuracy on real data:
-- **Hard Rules**: 94-96% (instant, ~10% of emails)
-- **ML Model**: 85-90% (fast, ~85% of emails)
-- **LLM Review**: 92-95% (slower, ~5% uncertain cases)
-- **Overall**: 90-94% (weighted average)
-
-## Retraining
-
-To retrain the model:
-
-```bash
-python -m src.cli train \
-  --source enron \
-  --output models/new_model.pkl \
-  --limit 10000
-```
-
-## Troubleshooting
-
-### Model Not Loading
-1. Check file exists: `src/models/pretrained/classifier.pkl`
-2. Try to load directly:
-   ```python
-   import pickle
-   with open('src/models/pretrained/classifier.pkl', 'rb') as f:
-       data = pickle.load(f)
-   print(data.keys())
-   ```
-3. Ensure pickle format is correct
-
-### Low Accuracy
-1. Model may be underfitted - train on more data
-2. Feature extraction may need tuning
-3. Categories may need adjustment
-4. Consider LLM review for uncertain cases
-
-### Slow Predictions
-1. Use embedding cache for batch processing
-2. Implement parallel processing
-3. Consider quantization for LightGBM model
-4. Profile feature extraction step

-
-extractor = FeatureExtractor()
-trainer = ModelTrainer(extractor, ['junk', 'transactional', 'auth', 'newsletters',
-                                     'social', 'automated', 'conversational', 'work',
-                                     'personal', 'finance', 'travel', 'unknown'])
-
-# Train (takes 5-10 minutes on this laptop)
-results = trainer.train([(e, 'unknown') for e in emails])
-trainer.save_model('src/models/pretrained/classifier.pkl')
-"
-
-# Verify
-python tools/setup_real_model.py --check
-```
-

-
-## Testing Your Setup
-
-### Framework Validation
-```bash
-# Test configuration loading
-python -m src.cli test-config
-
-# Test Ollama (if running locally)
-python -m src.cli test-ollama
-
-# Run full test suite
-pytest tests/ -v
-```
-
-### Mock Pipeline (No Real Data Needed)
-```bash
-python -m src.cli run --source mock --output test_results/
-```
-
-### Real Model Verification
-```bash
-python tools/setup_real_model.py --check
-```
-
-### Gmail Connection Test
-```bash
-python -m src.cli test-gmail
-```
-
----
-
-## Performance Expectations
-
-### With Mock Model (Testing)
-- Feature extraction: ~50-100ms per email
-- ML prediction: ~10-20ms per email
-- Total time for 100 emails: ~30-40 seconds
-
-### With Real Model (Production)
-- Feature extraction: ~50-100ms per email
-- ML prediction: ~5-10ms per email (LightGBM is faster)
-- LLM review (5% of emails): ~2-5 seconds per email
-- Total time for 80k emails: 15-25 minutes
-
-### Calibration Phase
-- Sampling: 1-2 minutes
-- LLM category discovery: 2-3 minutes
-- Model training: 5-10 minutes
-- Total: 10-15 minutes
-
----
-
-## Troubleshooting
-
-### Problem: "Model not found" but framework running
-**Solution**: This is normal - system uses mock model automatically
-```bash
-python tools/setup_real_model.py --check  # Shows current status
-```
-
-### Problem: Ollama tests failing
-**Solution**: Ollama is optional, LLM review will skip gracefully
-```bash
-# Not critical - framework has graceful fallback
-python -m src.cli run --source mock
-```
-
-### Problem: Gmail connection fails
-**Solution**: Gmail is optional, test with mock first
-```bash
-python -m src.cli run --source mock --output results/
-```
-
-### Problem: Low accuracy with mock model
-**Expected behavior**: Mock model is for framework testing only
-```python
-# Check model info
-from src.classification.ml_classifier import MLClassifier
-c = MLClassifier()
-print(c.get_info())  # Shows is_mock: True
-```
-

-## What NOT to Do
-
-❌ **Do NOT**:
-- Try to use mock model in production (it's not accurate)
-- Process all emails before testing with 100
-- Skip Gmail credential setup (use mock for testing instead)
-- Modify core classifier code (framework is complete)
-- Skip the test suite validation
-- Use Ollama if laptop is low on resources (graceful fallback available)
-
-✅ **DO**:
-- Test with mock first
-- Integrate real model before processing
-- Start with 100 emails then scale
-- Review results and adjust thresholds
-- Keep this file for reference
-- Use the tools provided for model integration
-
----
-
-## Support & Questions

----
-
-## What's NOT Included (By Design)
-
-### ❌ Not Here (Intentionally Deferred)
-1. **Real Trained Model** - You decide: train on Enron or download
-2. **Gmail Credentials** - Requires your Google Cloud setup
-3. **Live Email Processing** - Requires #1 and #2 above
-
-### ✅ Why This Is Good
-- Framework is clean and unopinionated
-- Your model, your training decisions
-- Your credentials, your privacy
-- Complete freedom to customize
-
----
-
-## Key Decisions Made
-
-### 1. Mock Model Strategy
-- Framework uses clearly labeled mock for testing
-- No deception (explicit warnings in output)
-- Real model integration framework ready
-- Smooth path to production
-
-### 2. Modular Architecture
-- Each component can be tested independently
-- Easy to swap components (e.g., different LLM)
-- Framework doesn't force decisions
-- Extensible design
-
-### 3. Three-Tier Classification
-- Hard rules for instant/certain cases
-- ML for bulk processing
-- LLM for uncertain/complex cases
-- Balances speed and accuracy
-
-### 4. Learning Systems
-- Threshold adjustment from LLM feedback
-- Pattern learning from sender data
-- Continuous improvement without retraining
-- Dynamic tuning
-
-### 5. Graceful Degradation
-- Works without LLM (falls back to ML)
-- Works without Gmail (uses mock)
-- Works without real model (uses mock)
-- No single point of failure
-
----
-
-## Performance Characteristics
-
-### CPU Usage
-- Feature extraction: Single-threaded, parallelizable
-- ML prediction: ~5-10ms per email
-- LLM call: ~2-5 seconds per email
-- Embedding cache: Reduces recomputation by 50-80%
-
-### Memory Usage
-- Embeddings cache: ~200-500MB (configurable)
-- Batch processing: Configurable batch size
-- Model (LightGBM): ~50-100MB
-- Total runtime: ~500MB-1GB
-
-### Accuracy
-- Hard rules: 94-96% (pattern-based)
-- ML alone: 85-90% (LightGBM)
-- ML + LLM: 90-94% (adaptive)
-- With fine-tuning: 95%+ possible
-
----
-
-## Deployment Options
-
-### Option 1: Local Development
-```bash
-python -m src.cli run --source mock --output local_results/
-```
-- No external dependencies
-- Perfect for testing
-- Mock model for framework validation
-
-### Option 2: With Ollama (Local LLM)
-```bash
-# Start Ollama with qwen model
-python -m src.cli run --source mock --output results/
-```
-- Local LLM processing (no internet)
-- Privacy-first operation
-- Careful resource usage
-
-### Option 3: Cloud Integration
-```bash
-# With OpenAI API
-python -m src.cli run --source gmail --output results/
-```
-- Real Gmail integration
-- Cloud LLM support
-- Full production setup
-

-# EMAIL SORTER - RESEARCH FINDINGS
-
-Date: 2024-10-21
-Research Phase: Complete
-
----
-
-## SEARCH SUMMARY
-
-We conducted web research on:
-1. Email classification benchmarks (2024)
-2. XGBoost vs LightGBM for embeddings and mixed features
-3. Competition analysis (existing email organizers)
-4. Gradient boosting with embeddings + categorical features
-
----
-
-## 1. EMAIL CLASSIFICATION BENCHMARKS (2024)
-
-### Key Findings
-
-**Enron Dataset Performance:**
-- Traditional ML (SVM, Random Forest): **95-98% accuracy**
-- Deep Learning (DNN-BiLSTM): **98.69% accuracy**
-- Transformer models (BERT, RoBERTa, DistilBERT): **~99% accuracy**
-- LLMs (GPT-4): **99.7% accuracy** (phishing detection)
-- Ensemble stacking methods: **98.8% accuracy**, F1: 98.9%
-
-**Zero-Shot LLM Performance:**
-- Flan-T5: **94% accuracy**, F1: 90%
-- GPT-4: **97% accuracy**, F1: 95%
-
-**Key insight:** Modern ML methods can achieve 95-98% accuracy on email classification. Our hybrid target of 94-96% is realistic and competitive.
-
-### Dataset Details
-
-- **Enron Email Dataset**: 500,000+ emails from 150 employees
-- **EnronQA benchmark**: 103,638 emails with 528,304 Q&A pairs
-- **AESLC**: Annotated Enron Subject Line Corpus (for summarization)
-
-### Implications for Our System
-
-- Our 94-96% target is achievable and competitive
-- LightGBM + embeddings should hit 92-95% easily
-- LLM review for 5-10% uncertain cases will push us to upper range
-- Attachment analysis is a differentiator (not tested in benchmarks)

-## 2. LIGHTGBM VS XGBOOST FOR HYBRID FEATURES
-
-### Decision: LightGBM WINS 🏆
-
-| Feature | LightGBM | XGBoost | Winner |
-|---------|----------|---------|--------|
-| **Categorical handling** | Native support | Needs encoding | ✅ LightGBM |
-| **Speed** | 2-5x faster | Baseline | ✅ LightGBM |
-| **Memory** | Very efficient | Standard | ✅ LightGBM |
-| **Accuracy** | Equivalent | Equivalent | Tie |
-| **Mixed features** | 4x speedup | Slower | ✅ LightGBM |
-
-### Key Advantages of LightGBM
-
-1. **Native Categorical Support**
-   - LightGBM splits categorical features by equality
-   - No need for one-hot encoding
-   - Avoids dimensionality explosion
-   - XGBoost requires manual encoding (label, mean, or one-hot)
-
-2. **Speed Performance**
-   - 2-5x faster than XGBoost in general
-   - **4x speedup** on datasets with categorical features
-   - Same AUC performance, drastically better speed
-
-3. **Memory Efficiency**
-   - Preferable for large, sparse datasets
-   - Better for memory-constrained environments
-
-4. **Embedding Compatibility**
-   - Handles dense numerical features (embeddings) excellently
-   - Native categorical handling for mixed feature types
-   - Perfect for our hybrid approach
-
-### Research Quote
-
-> "LightGBM is significantly faster than XGBoost but delivers almost equivalent performance. In tests, both algorithms achieve pretty much the same AUC, but LightGBM runs from 2 to 5 times faster."
-
-### Implications for Our System
-
-**Perfect for our hybrid features:**
-```python
-features = {
-    'embeddings': [384 dense numerical],      # ✅ LightGBM handles
-    'patterns': [20 boolean/numerical],       # ✅ LightGBM handles
-    'sender_type': 'corporate',               # ✅ LightGBM native categorical
-    'time_of_day': 'morning',                 # ✅ LightGBM native categorical
-}
-# No encoding needed! 4x faster than XGBoost with encoding
-```

-## 3. COMPETITION ANALYSIS
-
-### Cloud-Based Email Organizers (2024)
-
-| Tool | Price | Features | Privacy | Accuracy Estimate |
-|------|-------|----------|---------|-------------------|
-| **SaneBox** | $7-15/mo | AI filtering, smart folders | ❌ Cloud | ~85% |
-| **Clean Email** | $10-30/mo | 30+ smart filters, bulk ops | ❌ Cloud | ~80% |
-| **Spark** | Free/Paid | Smart inbox, categorization | ❌ Cloud | ~75% |
-| **EmailTree.ai** | Enterprise | NLP classification, routing | ❌ Cloud | ~90% |
-| **Mailstrom** | $30-50/yr | Bulk analysis, categorization | ❌ Cloud | ~70% |
-
-### Key Features They Offer
-
-**Common capabilities:**
-- Automatic categorization (newsletters, social, etc.)
-- Smart folders based on sender/topic
-- Bulk operations (archive, delete)
-- Unsubscribe management
-- Search and filter
-
-**What they DON'T offer:**
-- ❌ Local processing (all require cloud upload)
-- ❌ Attachment content analysis
-- ❌ One-time cleanup (all are subscriptions)
-- ❌ Offline capability
-- ❌ Custom LLM integration
-- ❌ Open source / distributable
-
-### Our Competitive Advantages
-
-✅ **100% LOCAL** - No data leaves the machine
-✅ **Privacy-first** - Perfect for business owners with sensitive data
-✅ **One-time use** - No subscription, pay per job or DIY
-✅ **Attachment analysis** - Extract and classify PDF/DOCX content
-✅ **Customizable** - Adapts to each inbox via calibration
-✅ **Open source potential** - Distributable as Python wheel
-✅ **Offline capable** - Works without internet after setup
-
-### Market Gap Identified
-
-**Target customers:**
-- Self-employed / business owners with 10k-100k+ emails
-- Can't/won't upload to cloud (privacy, GDPR, security concerns)
-- Want one-time cleanup, not ongoing subscription
-- Tech-savvy enough to run Python tool or hire someone to run it
-- Have sensitive business correspondence, invoices, contracts
-
-**Pain point:**
-> "I've thought about just deleting it all, but there's some stuff I need to keep..."
-
-**Our solution:**
-- Local processing (100% private)
-- Smart classification (94-96% accurate)
-- Attachment analysis (find those invoices!)
-- One-time fee or DIY
-
-**Pricing comparison:**
-- SaneBox: $120-180/year subscription
-- Clean Email: $120-360/year subscription
-- **Us**: $50-200 one-time job OR free (DIY wheel)

-## 4. GRADIENT BOOSTING WITH EMBEDDINGS
-
-### Key Finding: CatBoost Has Embedding Support
-
-**GB-CENT Model** (Gradient Boosted Categorical Embedding and Numerical Trees):
-- Combines latent factor embeddings with tree components
-- Handles categorical features via low-dimensional representation
-- Captures nonlinear interactions of numerical features
-- Best of both worlds approach
-
-**CatBoost's "killer feature":**
-> "CatBoost has a killer feature that knows how to work with embeddings, though this is not well-documented."
-
-**Performance insights:**
-- Embeddings both as a feature AND as separate numerical features → best quality
-- Native categorical handling has slight edge over encoded approaches
-- One-hot encoding generally performs poorly (especially with limited tree depth)
-
-### Implications for Our System
-
-**LightGBM strategy (validated by research):**
-```python
-import lightgbm as lgb
-
-# Combine embeddings + categorical features
-X = np.concatenate([
-    embeddings,              # 384 dense numerical
-    pattern_booleans,        # 20 numerical (0/1)
-    structural_numerical     # 10 numerical (counts, lengths)
-], axis=1)
-
-# Specify categorical features by name
-categorical_features = ['sender_domain_type', 'time_of_day', 'day_of_week']
-
-model = lgb.LGBMClassifier(
-    categorical_feature=categorical_features,  # Native handling
-    n_estimators=200,
-    learning_rate=0.1,
-    max_depth=8
-)
-
-model.fit(X, y)
-```
-
-**Why this works:**
-- LightGBM handles embeddings (dense numerical) excellently
-- Native categorical handling for domain_type, time_of_day, etc.

-## 5. SENTENCE EMBEDDINGS FOR EMAIL
-
-### all-MiniLM-L6-v2 - The Sweet Spot
-
-**Model specs:**
-- Size: 23MB (tiny!)
-- Dimensions: 384 (vs 768 for larger models)
-- Speed: ~100 emails/sec on CPU
-- Accuracy: 85-95% on email/text classification tasks
-- Pretrained on 1B+ sentence pairs
-
-**Why it's perfect for us:**
-- Small enough to bundle with wheel distribution
-- Fast on CPU (no GPU required)
-- Semantic understanding (handles synonyms, paraphrasing)
-- Works with short text (emails are perfect)
-- No fine-tuning needed (pretrained is excellent)
-
-### Structured Embeddings (Our Innovation)
-
-Instead of naive embedding:
-```python
-# BAD
-text = f"{subject} {body}"
-embedding = model.encode(text)
-```
-
-**Our approach (parameterized headers):**
-```python
-# GOOD - gives model rich context
-text = f"""[EMAIL_METADATA]
-sender_type: corporate
-has_attachments: true
-[DETECTED_PATTERNS]
-has_otp: false
-has_invoice: true
-[CONTENT]
-subject: {subject}
-body: {body[:300]}
-"""
-embedding = model.encode(text)
-```
-
-**Research-backed benefit:** 5-10% accuracy boost from structured context
-
----
-
-## 6. ATTACHMENT ANALYSIS (COMPETITIVE ADVANTAGE)
-
-### What Competitors Do
-
-**Most tools:**
-- Note "has attachment: true/false"
-- Maybe detect attachment type (PDF, DOCX, etc.)
-- **DO NOT** extract or analyze attachment content
-
-### What We Can Do
-
-**Simple extraction (fast, high value):**
-```python
-if attachment_type == 'pdf':
-    text = extract_pdf_text(attachment)  # PyPDF2 library
-
-    # Pattern matching in PDF
-    has_invoice = 'invoice' in text.lower()
-    has_account_number = bool(re.search(r'account\s*#?\d+', text))
-    has_total_amount = bool(re.search(r'total.*\$\d+', text, re.I))
-
-    # Boost classification confidence
-    if has_invoice and has_account_number:
-        category = 'transactional'  # 99% confidence
-
-if attachment_type == 'docx':
-    text = extract_docx_text(attachment)  # python-docx library
-    word_count = len(text.split())
-
-    # Long documents might be contracts, reports
-    if word_count > 1000:
-        category_hint = 'work'
-```
-
-**Business owner value:**
-- "Find all invoices" → includes PDFs with invoice content
-- "Financial documents" → PDFs with account numbers
-- "Contracts" → DOCX files with legal terms
-- "Reports" → Long DOCX or PDF files
-
-**Implementation:**
-- Use PyPDF2 for PDFs (<5MB size limit)
-- Use python-docx for Word docs
-- Use openpyxl for simple Excel files
-- Flag complex/large attachments for review
-
----
-
-## 7. PERFORMANCE OPTIMIZATION
-
-### Batching Strategy (Critical)
-
-**Embedding generation bottleneck:**
-- Sequential: 80,000 emails × 10ms = 13 minutes
-- Batched (128 emails): 80,000 ÷ 128 × 100ms = ~1 minute
-
-**LLM processing optimization:**
-- Don't send 1500 individual requests during calibration
-- Batch 10-20 emails per prompt → 75-150 requests instead
-- Compress sample if needed (1500 → 500 smarter selection)
-
-### Expected Performance (Revised)
-
-```
-80,000 emails breakdown:
-├─ Calibration (500 compressed samples): 2-3 min
-├─ Pattern detection (all 80k): 10 sec
-├─ Embedding generation (batched): 1-2 min
-├─ LightGBM classification: 3 sec
-├─ Hard rules (10%): instant
-├─ LLM review (5%, batched): 4 min
-└─ Export: 2 min
-
-Total: ~10-12 minutes (optimistic)
-Total: ~15-20 minutes (realistic with overhead)
-```

-## 8. SECURITY & PRIVACY ADVANTAGES
-
-### Why Local Processing Matters
-
-**GDPR considerations:**
-- Cloud upload = data processing agreement needed
-- Local processing = no third-party involvement
-- Business emails often contain sensitive data
-
-**Privacy concerns:**
-- Client lists, pricing, contracts
-- Financial information, invoices
-- Personal health information (if medical business)
-- Legal correspondence
-
-**Our advantage:**
-- 100% local processing
-- No data retention
-- No cloud storage
-- Fresh repo per job (isolation)
-
----

-Yeah — your instinct is solid here, Brett.
-For the kind of **multi-category, fast, local, high-volume** classification system you’re building, training your own model on your own labelled data will almost certainly give **better and more controllable results** than trying to stretch an off-the-shelf model.
-
-Let’s break this down clearly — especially what **sentence-transformers** brings to the table and why it’s a good fit for your hybrid architecture.
-
----
-
-## 🧠 What Sentence Transformers Actually Do
-
-A **sentence transformer** is a model that converts a piece of text (e.g. subject line, short body snippet, sender info) into a **dense vector embedding** — basically a fixed-length numerical representation that captures its semantic meaning.
-
-Once you have embeddings, classification becomes a **simple, fast** downstream problem:
-
-* Instead of training a giant deep network,
-* You train a **small, lightweight model** (like Logistic Regression, XGBoost, or a simple neural head) on top of those embeddings.
-
----
-
-## 🚀 Why This Is a Great Fit for Your Email Sorter
-
-| Sentence Transformers                                       | Why it matters for you                                                        |
-| ----------------------------------------------------------- | ----------------------------------------------------------------------------- |
-| **Pretrained models** already “understand” general language | So you don’t need massive datasets to get good results.                       |
-| **Fast inference**                                          | Embedding generation can run on CPU or GPU and is easy to parallelise.        |
-| **Stable + deterministic**                                  | Embeddings are consistent across runs (unlike LLM zero-shot answers).         |
-| **Lightweight training**                                    | You can train a classifier on top with a few thousand labelled samples.       |
-| **Supports multi-class** easily                             | Perfect for your 12 category types.                                           |
-| **Re-usable**                                               | One universal model for all inboxes; just retrain the top layer occasionally. |
-
----
-
-## 🏗️ How It Would Work in Your Pipeline
-
-### 1. **Use the LLM once** to label your initial batch (e.g. 1.5k–5k emails).
-
-This gives you your **bootstrapped labelled dataset**.
-
-### 2. **Generate embeddings**
-
-* Take **subject**, **sender domain**, and optionally a short **body snippet**.
-* Pass through sentence transformer → get 768-dimensional vector (typical).
-* Save those embeddings alongside labels.
-
-### 3. **Train a classifier** on top
-
-A lightweight model like:
-
-* **Logistic Regression** (fastest),
-* **XGBoost / LightGBM** (slightly heavier, more accuracy),
-* or even a shallow **MLP** if you want.
-
-This becomes your **universal email classifier**.
-
-### 4. **Run in production**
-
-* New email comes in → embed text → run classifier → get category + confidence.
-* If below threshold → send to LLM for re-classification.
-
-This gives you **LLM semantic power** at training time, and **ML speed** at runtime.
-
----
-
-## 🧪 Practical Setup (Minimal)
-
-```python
-from sentence_transformers import SentenceTransformer
-from sklearn.linear_model import LogisticRegression
-
-# 1. Load a pre-trained embedding model
-model = SentenceTransformer("all-MiniLM-L6-v2")  # fast, lightweight
-
-# 2. Convert texts to embeddings
-texts = [f"{subject} {sender}" for subject, sender in your_email_data]
-embeddings = model.encode(texts, batch_size=64, show_progress_bar=True)
-
-# 3. Train a lightweight classifier
-clf = LogisticRegression(max_iter=1000)
-clf.fit(embeddings, labels)  # labels come from your LLM bootstrap
-
-# 4. Predict
-new_embedding = model.encode(["Subject from new email"])
-pred = clf.predict(new_embedding)
-conf = clf.predict_proba(new_embedding)
-```
-
-* `all-MiniLM-L6-v2` is a fantastic starting model — small, fast, and surprisingly accurate.
-* You can fine-tune the sentence transformer later if you want **extra precision**.
-
----
-
-## 🧠 Why It’s Easier Than Full Fine-Tuning
-
-You *don’t* need to train the transformer itself (at least not at the start).
-You’re just training the **top layer** (classifier). That means:
-
-* Training takes minutes, not hours.
-* You don’t need huge GPUs.
-* You can refresh or retrain easily with new data.
-
-Later on, if you want to **fine-tune the transformer itself** (so it “understands emails” more deeply), that’s an optional next step.
-
----
-
-## ⚡ Typical Results People See
-
-* With 2–5k labelled samples, sentence transformer embeddings + logistic regression can hit **85–95 % accuracy** on email category tasks.
-* Inference time is **<5 ms per email** on CPU.
-* Works well for both generic and user-specific inboxes.
-
----
-
-## 🪜 Suggested Path for You
-
-1. Use your **LLM pass** to generate labels on your first big inbox.
-2. Generate embeddings with a pretrained MiniLM.
-3. Train a logistic regression or XGBoost model.
-4. Run it on the next inbox → see how it performs.
-5. (Optional) Fine-tune the transformer if you want to push performance higher.
-
----
-
-👉 In short:
-Yes — sentence transformers are **perfect** for this.
-They give you **semantic power without LLM overhead**, are **easy to train**, and will make your hybrid classifier **extremely fast and accurate** after that first run.
-
-If you want, I can give you a **tiny starter training script** (30–40 lines) that does the embedding + classifier training from your first LLM-labelled dataset. Would you like that?

+
+## Gmail Setup
+
+### 1. Create OAuth Credentials
+
+1. Go to [Google Cloud Console](https://console.cloud.google.com)
+2. Create a new project (or select existing)
+3. Enable Gmail API
+4. Go to "Credentials" → "Create Credentials" → "OAuth client ID"
+5. Choose "Desktop app" as application type
+6. Download the JSON file
+7. Save as `credentials/gmail/account1.json` (or account2.json, account3.json)
+
+### 2. Credential File Format
+
+```json
+{
+  "installed": {
+    "client_id": "YOUR_CLIENT_ID.apps.googleusercontent.com",
+    "project_id": "your-project-id",
+    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
+    "token_uri": "https://oauth2.googleapis.com/token",
+    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
+    "client_secret": "YOUR_CLIENT_SECRET",
+    "redirect_uris": ["http://localhost"]
+  }
+}
+```
+
+### 3. Usage
+
+```bash
+# Account 1
+python -m src.cli run --source gmail --credentials credentials/gmail/account1.json --limit 1000
+
+# Account 2
+python -m src.cli run --source gmail --credentials credentials/gmail/account2.json --limit 1000
+
+# Account 3
+python -m src.cli run --source gmail --credentials credentials/gmail/account3.json --limit 1000
+```
+
+## Outlook Setup
+
+### 1. Register Azure AD Application
+
+1. Go to [Azure Portal](https://portal.azure.com/#blade/Microsoft_AAD_RegisteredApps)
+2. Click "New registration"
+3. Name your app (e.g., "Email Sorter")
+4. Choose "Accounts in any organizational directory and personal Microsoft accounts"
+5. Set Redirect URI to "Public client/native" with `http://localhost:8080`
+6. Click "Register"
+7. Copy the "Application (client) ID"
+8. (Optional) Create a client secret in "Certificates & secrets" for server apps
+
+### 2. Configure API Permissions
+
+1. Go to "API permissions"
+2. Click "Add a permission"
+3. Choose "Microsoft Graph"
+4. Select "Delegated permissions"
+5. Add:
+   - Mail.Read
+   - Mail.ReadWrite
+6. Click "Grant admin consent" (if you have admin rights)
+
+### 3. Credential File Format
+
+```json
+{
+  "client_id": "YOUR_AZURE_APP_CLIENT_ID",
+  "client_secret": "YOUR_CLIENT_SECRET_OPTIONAL",
+  "tenant_id": "common",
+  "redirect_uri": "http://localhost:8080"
+}
+```
+
+**Note:** `client_secret` is optional for desktop apps using device flow authentication.
+
+### 4. Usage
+
+```bash
+# Account 1
+python -m src.cli run --source outlook --credentials credentials/outlook/account1.json --limit 1000
+
+# Account 2
+python -m src.cli run --source outlook --credentials credentials/outlook/account2.json --limit 1000
+
+# Account 3
+python -m src.cli run --source outlook --credentials credentials/outlook/account3.json --limit 1000
+```
+
+## IMAP Setup
+
+### 1. Get IMAP Credentials
+
+For Gmail IMAP:
+1. Enable 2-factor authentication on your Google account
+2. Go to https://myaccount.google.com/apppasswords
+3. Generate an "App Password" for "Mail"
+4. Use this app password (not your real password)
+
+For Outlook/Office365 IMAP:
+- Host: `outlook.office365.com`
+- Port: `993`
+- Use your regular password or app password
+
+### 2. Credential File Format
+
+```json
+{
+  "host": "imap.gmail.com",
+  "port": 993,
+  "username": "your.email@gmail.com",
+  "password": "your_app_password_or_password",
+  "use_ssl": true
+}
+```
+
+### 3. Usage
+
+```bash
+# Account 1
+python -m src.cli run --source imap --credentials credentials/imap/account1.json --limit 1000
+
+# Account 2
+python -m src.cli run --source imap --credentials credentials/imap/account2.json --limit 1000
+
+# Account 3
+python -m src.cli run --source imap --credentials credentials/imap/account3.json --limit 1000
+```
+
+## Security Notes
+
+### Important Security Practices
+
+1. **Never commit credentials to git**
+   - The `.gitignore` file excludes `credentials/` directory
+   - Only `.example` files should be committed
+
+2. **File permissions**
+   - Set restrictive permissions: `chmod 600 credentials/*/*.json`
+
+3. **Credential rotation**
+   - Rotate credentials periodically
+   - Revoke unused credentials in provider dashboards
+
+4. **Separation**
+   - Keep each account's credentials in separate files
+   - Use descriptive names (account1, account2, account3)
+
+### Credential Storage Locations
+
+**This directory** (`credentials/`) is for:
+- Development and testing
+- Personal use
+- Single-user deployments
+
+**NOT recommended for:**
+- Production servers (use environment variables or secret managers)
+- Multi-user systems (use proper authentication systems)
+- Public repositories (credentials would be exposed)
+
+## Troubleshooting
+
+### Gmail Issues
+
+**Error: "credentials_path required"**
+- Ensure you're passing `--credentials` flag
+- Verify file exists and path is correct
+
+**Error: "GMAIL DEPENDENCIES MISSING"**
+- Install dependencies: `pip install google-api-python-client google-auth-oauthlib`
+
+**Error: "CREDENTIALS FILE NOT FOUND"**
+- Check file exists at specified path
+- Ensure filename is correct (case-sensitive)
+
+### Outlook Issues
+
+**Error: "client_id required"**
+- Verify JSON file has `client_id` field
+- Check Azure app registration
+
+**Error: "OUTLOOK DEPENDENCIES MISSING"**
+- Install dependencies: `pip install msal requests`
+
+**Authentication timeout**
+- Complete device flow authentication within time limit
+- Check browser for authentication prompt
+- Verify Azure app has correct permissions
+
+### IMAP Issues
+
+**Error: "Authentication failed"**
+- For Gmail: Use app password, not regular password
+- Enable "Less secure app access" if using regular password
+- Verify username/password are correct
+
+**Connection timeout**
+- Check host and port are correct
+- Verify firewall isn't blocking IMAP port
+- Test connection with: `telnet imap.gmail.com 993`
+
+## Testing Credentials
+
+Test each credential file before running full classification:
+
+```bash
+# Test Gmail connection
+python -m src.cli test-gmail --credentials credentials/gmail/account1.json
+
+# Test Outlook connection
+python -m src.cli test-outlook --credentials credentials/outlook/account1.json
+
+# Test IMAP connection
+python -m src.cli test-imap --credentials credentials/imap/account1.json
+```
+
+## Dependencies
+
+### Gmail
+```bash
+pip install google-api-python-client google-auth-oauthlib google-auth-httplib2
+```
+
+### Outlook
+```bash
+pip install msal requests
+```
+
+### IMAP
+No additional dependencies required (uses Python standard library).
+
+---
+
+**Remember:** Keep your credentials secure and never share them publicly!

+# Email Classification Methods: Comparative Analysis
+
+## Executive Summary
+
+This document compares three email classification approaches tested on an 801-email personal Gmail dataset:
+
+| Method | Accuracy | Time | Best For |
+|--------|----------|------|----------|
+| ML-Only | 54.9% | 5 sec | 10k+ emails, speed critical |
+| ML+LLM Fallback | 93.3% | 3.5 min | 1k-10k emails, balanced |
+| Agent Analysis | 99.8% | 15-30 min | <1k emails, deep insights |
+
+**Key Finding:** The ML pipeline is overkill for datasets under ~5,000 emails. A 10-15 minute agent pre-analysis phase could dramatically improve ML accuracy for larger datasets.
+
+---
+
+## Test Dataset Profile
+
+| Characteristic | Value |
+|----------------|-------|
+| Total Emails | 801 |
+| Date Range | 20 years (2005-2025) |
+| Unique Senders | ~150 |
+| Automated % | 48.8% |
+| Personal % | 1.6% |
+| Structure Level | MEDIUM-HIGH |

+## Method 1: ML-Only Classification
+
+### Configuration
+```yaml
+model: LightGBM (pretrained on Enron dataset)
+embeddings: all-minilm:l6-v2 (384 dimensions)
+threshold: 0.55 confidence
+categories: 11 generic (Work, Updates, Financial, etc.)
+```
+
+### Results
+
+| Metric | Value |
+|--------|-------|
+| Accuracy Estimate | 54.9% |
+| High Confidence (>55%) | 477 (59.6%) |
+| Low Confidence | 324 (40.4%) |
+| Processing Time | ~5 seconds |
+| LLM Calls | 0 |
+
+### Category Distribution (ML-Only)
+
+| Category | Count | % |
+|----------|-------|---|
+| Work | 243 | 30.3% |
+| Technical | 198 | 24.7% |
+| Updates | 156 | 19.5% |
+| External | 89 | 11.1% |
+| Operational | 45 | 5.6% |
+| Financial | 38 | 4.7% |
+| Other | 32 | 4.0% |
+
+### Limitations Observed
+
+1. **Domain Mismatch:** Trained on corporate Enron emails, applied to personal Gmail
+2. **Generic Categories:** "Work" and "Technical" absorbed everything
+3. **No Sender Intelligence:** Didn't leverage sender domain patterns
+4. **High Uncertainty:** 40% needed LLM review but got none
+
+### When ML-Only Works
+
+- 10,000+ emails where speed matters
+- Corporate/enterprise datasets similar to training data
+- Pre-filtering before human review
+- Cost-constrained environments (no LLM API)
+
+---
+
+## Method 2: ML + LLM Fallback
+
+### Configuration
+```yaml
+ml_model: LightGBM (same as above)
+llm_model: qwen3-coder-30b (vLLM on localhost:11433)
+threshold: 0.55 confidence
+fallback_trigger: confidence < threshold
+```
+
+### Results
+
+| Metric | Value |
+|--------|-------|
+| Accuracy Estimate | 93.3% |
+| ML Classified | 477 (59.6%) |
+| LLM Classified | 324 (40.4%) |
+| Processing Time | ~3.5 minutes |
+| LLM Calls | 324 |
+
+### Category Distribution (ML+LLM)
+
+| Category | Count | % | Source |
+|----------|-------|---|--------|
+| Work | 243 | 30.3% | ML |
+| Technical | 156 | 19.5% | ML |
+| newsletters | 98 | 12.2% | LLM |
+| junk | 87 | 10.9% | LLM |
+| transactional | 76 | 9.5% | LLM |
+| Updates | 62 | 7.7% | ML |
+| auth | 45 | 5.6% | LLM |
+| Other | 34 | 4.2% | Mixed |
+
+### Improvements Over ML-Only
+
+1. **New Categories:** LLM introduced "newsletters", "junk", "transactional", "auth"
+2. **Better Separation:** Marketing vs. transactional distinguished
+3. **Higher Confidence:** 93.3% vs 54.9% accuracy estimate
+
+### Limitations Observed
+
+1. **Category Inconsistency:** ML uses "Updates", LLM uses "newsletters"
+2. **No Sender Context:** Still classifying email-by-email
+3. **Generic LLM Prompt:** Doesn't know about user's specific interests
+4. **Time Cost:** 324 sequential LLM calls at ~0.6s each
+
+### When ML+LLM Works
+
+- 1,000-10,000 emails
+- Mixed automated/personal content
+- When accuracy matters more than speed
+- Local LLM available (cost-free fallback)
+
+---
+
+## Method 3: Agent Analysis (Manual)
+

+

+
+## Enhancement Recommendations
+
+### 1. Pre-Analysis Phase (10-15 min investment)
+
+**Concept:** Run agent analysis BEFORE ML classification to:
+- Discover sender domains and their purposes
+- Identify category patterns specific to dataset
+- Generate custom classification rules
+- Create sender-to-category mappings
+
+**Implementation:**
+```python
+class PreAnalysisAgent:
+    def analyze(self, emails: List[Email], sample_size=100):
+        # Phase 1: Sender domain clustering
+        domains = self.cluster_by_sender_domain(emails)
+
+        # Phase 2: Subject pattern extraction
+        patterns = self.extract_subject_patterns(emails)
+
+        # Phase 3: Generate custom categories
+        categories = self.generate_categories(domains, patterns)
+
+        # Phase 4: Create sender-category mapping
+        sender_map = self.map_senders_to_categories(domains, categories)
+
+        return {
+            'categories': categories,
+            'sender_map': sender_map,
+            'patterns': patterns
+        }
+```
+
+**Expected Impact:**
+- Accuracy: 54.9% → 85-90% (ML-only with pre-analysis)
+- Time: +10 min setup, same runtime
+- Best for: 5,000+ email datasets
+
+### 2. Sender-First Classification
+
+**Concept:** Classify by sender domain BEFORE content analysis:
+
+```python
+SENDER_CATEGORIES = {
+    # High-volume automated
+    'mutualart.com': ('Notifications', 'Art Alerts'),
+    'tripadvisor.com': ('Notifications', 'Travel Marketing'),
+    'ebay.com': ('Shopping', 'Marketplace'),
+    'spotify.com': ('Entertainment', 'Streaming'),
+
+    # Security - never auto-filter
+    'accounts.google.com': ('Security', 'Account Alerts'),
+
+    # Business
+    'businessprofile-noreply@google.com': ('Business', 'Reports'),
+}
+
+def classify(email):
+    domain = extract_domain(email.sender)
+    if domain in SENDER_CATEGORIES:
+        return SENDER_CATEGORIES[domain]  # 80% of emails
+    else:
+        return ml_classify(email)  # Fallback for 20%
+```
+
+**Expected Impact:**
+- Accuracy: 85-95% for known senders
+- Speed: 10x faster (skip ML for known senders)
+- Maintenance: Requires sender map updates
+
+### 3. Post-Analysis Enhancement
+
+**Concept:** Run agent analysis AFTER ML to:
+- Validate classification quality
+- Extract deeper insights
+- Generate reports and recommendations
+- Identify misclassifications
+
+**Implementation:**
+```python
+class PostAnalysisAgent:
+    def analyze(self, emails: List[Email], classifications: List[Result]):
+        # Validate: Check for obvious errors
+        errors = self.detect_misclassifications(emails, classifications)
+
+        # Enrich: Add metadata not captured by ML
+        enriched = self.extract_metadata(emails)
+
+        # Insights: Generate actionable recommendations
+        insights = self.generate_insights(emails, classifications)
+
+        return {
+            'corrections': errors,
+            'enrichments': enriched,
+            'insights': insights
+        }
+```
+
+### 4. Dataset Size Routing
+
+**Concept:** Automatically choose method based on volume:
+
+```python
+def choose_method(email_count: int, time_budget: str = 'normal'):
+    if email_count < 500:
+        return 'agent_only'  # Full agent analysis
+
+    elif email_count < 2000:
+        return 'agent_then_ml'  # Pre-analysis + ML
+
+    elif email_count < 10000:
+        return 'ml_with_llm'  # ML + LLM fallback
+
+    else:
+        return 'ml_only'  # Pure ML for speed
+```
+
+**Recommended Thresholds:**
+
+| Volume | Recommended Method | Rationale |
+|--------|-------------------|-----------|
+| <500 | Agent Only | ML overhead not worth it |
+| 500-2000 | Agent Pre-Analysis + ML | Investment pays off |
+| 2000-10000 | ML + LLM Fallback | Balanced approach |
+| >10000 | ML-Only | Speed critical |
+
+### 5. Hybrid Category System
+
+**Concept:** Merge ML categories with agent-discovered categories:
+
+```python
+# ML Generic Categories (trained)
+ML_CATEGORIES = ['Work', 'Updates', 'Technical', 'Financial', ...]
+
+# Agent-Discovered Categories (per-dataset)
+AGENT_CATEGORIES = {
+    'Art Alerts': {'parent': 'Updates', 'sender': 'mutualart.com'},
+    'Travel Marketing': {'parent': 'Updates', 'sender': 'tripadvisor.com'},
+    'AI Services': {'parent': 'Technical', 'keywords': ['anthropic', 'openai']},
+}
+
+def classify_hybrid(email, ml_result):
+    # First: Check agent-specific rules
+    for cat, rules in AGENT_CATEGORIES.items():
+        if matches_rules(email, rules):
+            return (cat, ml_result.category)  # Specific + generic
+
+    # Fallback: ML result
+    return (ml_result.category, None)
+```
+
+---
+
+## Implementation Roadmap
+
+### Phase 1: Quick Wins (1-2 hours)
+
+1. **Add sender-domain classifier**
+   - Map top 20 senders to categories
+   - Use as fast-path before ML
+   - Expected: +20% accuracy
+
+2. **Add dataset size routing**
+   - Check email count before processing
+   - Route small datasets to agent analysis
+   - Route large datasets to ML pipeline
+
+### Phase 2: Pre-Analysis Agent (4-8 hours)
+
+1. **Build sender clustering**
+   - Group emails by domain
+   - Calculate volume per domain
+   - Identify automated vs personal
+
+2. **Build pattern extraction**
+   - Find subject templates
+   - Extract IDs and tracking numbers
+   - Identify lifecycle stages
+
+3. **Generate sender map**
+   - Output: JSON mapping senders to categories
+   - Feed into ML pipeline as rules
+
+### Phase 3: Post-Analysis Enhancement (4-8 hours)
+
+1. **Build validation agent**
+   - Check low-confidence results
+   - Detect category conflicts
+   - Flag for review
+
+2. **Build enrichment agent**
+   - Extract order IDs
+   - Track lifecycles
+   - Generate insights
+
+3. **Integrate with HTML report**
+   - Add insights section
+   - Show lifecycle tracking
+   - Include recommendations
+
+---
+
+## Conclusion
+
+### Key Takeaways
+
+1. **ML pipeline is overkill for <5,000 emails** - Agent analysis provides better accuracy with similar time investment
+
+2. **Sender domain is the strongest signal** - 80%+ emails can be classified by sender alone
+
+3. **Pre-analysis investment pays off** - 10-15 min agent setup dramatically improves ML accuracy
+
+4. **One-size-fits-all doesn't work** - Route by dataset size for optimal results
+
+5. **Post-analysis adds unique value** - Lifecycle tracking and insights not possible with ML alone
+

+
+## Key Learnings from Research Sessions
+
+### Session 1: brett-gmail (801 emails, Personal Inbox)
+
+| Method | Accuracy | Time |
+|--------|----------|------|
+| ML-Only | 54.9% | ~5 sec |
+| ML+LLM | 93.3% | ~3.5 min |
+| Manual Agent | 99.8% | ~25 min |
+
+### Session 2: brett-microsoft (596 emails, Business Inbox)
+
+| Method | Accuracy | Time |
+|--------|----------|------|
+| Manual Agent | 98.2% | ~30 min |
+
+**Key Insight:** Business inboxes require different classification approaches than personal inboxes.
+
+---
+
+### 1. ML Pipeline is Overkill for Small Datasets
+
+| Dataset Size | Recommended Approach | Rationale |
+|--------------|---------------------|-----------|
+| <500 | Agent-only analysis | ML overhead exceeds benefit |
+| 500-2000 | Agent pre-scan + ML | Discovery improves ML accuracy |
+| 2000-10000 | ML + LLM fallback | Balanced speed/accuracy |
+| >10000 | ML-only (fast mode) | Speed critical at scale |
+
+**Evidence:** 801-email dataset achieved 99.8% accuracy with 25-min agent analysis vs 54.9% with pure ML.
+
+### 2. Agent Pre-Scan Adds Massive Value
+
+A 10-15 minute agent discovery phase before bulk classification:
+- Identifies dominant sender domains
+- Discovers subject patterns
+- Suggests optimal categories for THIS dataset
+- Can generate sender-to-category mappings
+
+**This is NOT the same as the full manual analysis.** It's a quick reconnaissance pass.
+
+### 3. Categories Should Serve Downstream Processing
+
+Don't optimize for human-readable labels. Optimize for routing decisions:
+
+| Category Type | Downstream Handler | Accuracy Need |
+|---------------|-------------------|---------------|
+| Junk/Marketing | Batch cleanup tool | LOW (errors OK) |
+| Newsletters | Summary aggregator | MEDIUM |
+| Transactional | Archive, searchable | MEDIUM |
+| Business | Knowledge graph | HIGH |
+| Personal | Human review | CRITICAL |
+| Security | Never auto-filter | CRITICAL |
+
+### 4. Risk-Based Accuracy Requirements
+
+Not all emails need the same classification confidence:
+
+```
+HIGH STAKES (must not miss):
+├─ Personal correspondence (sentimental value)
+├─ Security alerts (account safety)
+├─ Job applications (life-changing)
+└─ Financial/legal documents
+
+LOW STAKES (errors tolerable):
+├─ Marketing promotions
+├─ Newsletter digests
+├─ Automated notifications
+└─ Social media alerts
+```
+
+### 5. Spam Filtering is a Solved Problem
+
+Don't reinvent spam filtering. Gmail and Outlook do it well. This tool should:
+- Assume spam is already filtered
+- Focus on categorizing legitimate mail
+- Trust the upstream provider
+
+If spam does get through, a simple secondary filter could catch obvious cases, but this is low priority.
+
+### 6. Sender Domain is the Strongest Signal
+
+From the 801-email analysis:
+- Top 5 senders = 47.5% of all emails
+- Sender domain alone could classify 80%+ of automated emails
+- Subject patterns matter less than sender patterns
+
+**Implication:** A sender-first classification approach could dramatically speed up processing.
+
+### 7. Inbox Character Matters (NEW - Session 2)
+
+**Critical Discovery:** Before classifying emails, assess the inbox CHARACTER:
+
+| Inbox Type | Characteristics | Classification Approach |
+|------------|-----------------|------------------------|
+| **Personal/Consumer** | Subscription-heavy, marketing-dominant, automated 40-50% | Sender domain first |
+| **Business/Professional** | Client work, operations, developer tools 60-70% | Sender + Subject context |
+| **Mixed** | Both patterns present | Hybrid approach needed |
+
+**Evidence from brett-microsoft analysis:**
+- 73.2% Business/Professional content
+- Only 8.2% Personal content
+- Required client relationship tracking
+- Support case ID extraction valuable
+
+**Implications for Agent Pre-Scan:**
+1. First determine inbox character (business vs personal vs mixed)
+2. Select appropriate category templates
+3. Business inboxes need relationship context, not just sender domains
+
+### 8. Business Inboxes Need Special Handling (NEW - Session 2)
+
+Business/professional inboxes require additional classification dimensions:
+
+**Client Relationship Tracking:**
+- Same domain may have different contexts (internal vs external)
+- Client conversations span multiple senders
+- Subject threading matters more than in consumer inboxes
+
+**Support Case ID Extraction:**
+- Business inboxes often have case/ticket IDs connecting emails
+- Microsoft: Case #, TrackingID#
+- Other vendors: Ticket numbers, reference IDs
+- ID extraction should be first-class feature
+
+**Accuracy Expectations:**
+- Personal inboxes: 99%+ achievable with sender-first
+- Business inboxes: 95-98% achievable (more nuanced)
+- Accept lower accuracy ceiling, invest in risk-flagging
+
+### 9. Multi-Inbox Analysis Reveals Patterns (NEW - Session 2)
+
+Analyzing multiple inboxes from same user reveals:
+- **Inbox segregation patterns** - Gmail for personal, Outlook for business
+- **Cross-inbox senders** - Security alerts appear in both
+- **Category overlap** - Some categories universal, some inbox-specific
+
+**Implication:** Future feature could merge analysis across inboxes to build complete user profile.

+## Success Metrics
+
+### For This Tool
+
+| Metric | Target | Current |
+|--------|--------|---------|
+| Classification accuracy (large datasets) | >85% | 54.9% (ML), 93.3% (ML+LLM) |
+| Processing speed (10k emails) | <5 min | ~24 sec (ML-only) |
+| High-stakes miss rate | <1% | Not measured |
+| Setup time for new mailbox | <20 min | Variable |
+
+### For Ecosystem
+
+| Metric | Target |
+|--------|--------|
+| End-to-end mailbox processing | <2 hours for 10k |
+| User intervention needed | <10% of emails |
+| Downstream tool compatibility | 100% |
+
+---
+
+## Open Questions (To Resolve in 2025)
+
+1. **Category standardization**: Should categories be fixed across all users, or discovered per-mailbox?
+
+2. **Sender map sharing**: Can sender maps be shared across users? Privacy implications?
+
+3. **Incremental processing**: How to handle new emails added to already-processed mailboxes?
+
+4. **Multi-account support**: Same user, multiple email accounts?
+
+5. **Feedback integration**: How do corrections feed back into the system?

+
+## Summary
+
+**Email Sorter is a triage tool, not a complete solution.**
+
+Its job is to quickly sort emails into buckets so that specialized downstream tools can handle each bucket appropriately. The key insight from this research session is that an agent pre-scan phase, even just 10-15 minutes, dramatically improves classification accuracy for any dataset size.
+
+The ML pipeline is valuable for scale (10k+ emails) but overkill for smaller datasets. Risk-based accuracy means we can tolerate errors on junk but must be careful with personal correspondence.
+
+2025 development should focus on:
+1. Smart routing based on dataset size
+2. Agent pre-scan for discovery
+3. Standardized output for ecosystem integration
+4. Scale testing on real large mailboxes

+# Email Classification Report Format
+
+This document explains the HTML report generation system, its data sources, and how to customize it.
+
+## Overview
+
+The report generator creates a static HTML file from classification results. It requires enriched `results.json` with email metadata (subject, sender, date, etc.) - not just classification data.
+
+## Files Involved
+
+| File | Purpose |
+|------|---------|
+| `tools/generate_html_report.py` | Main report generator script |
+| `src/cli.py` | Classification CLI - outputs enriched `results.json` |
+| `src/export/exporter.py` | Legacy exporter (JSON/CSV) - not used for HTML |
+
+## Data Flow
+
+```
+Email Source (.eml/.msg files)
+        ↓
+   src/cli.py (classification)
+        ↓
+   results.json (enriched with metadata)
+        ↓
+   tools/generate_html_report.py
+        ↓
+   report.html (static, self-contained)
+```
+
+## Usage
+
+### Generate Report
+
+```bash
+python tools/generate_html_report.py \
+  --input /path/to/results.json \
+  --output /path/to/report.html
+```
+
+If `--output` is omitted, creates `report.html` in same directory as input.
+
+### Full Workflow
+
+```bash
+# 1. Classify emails
+python -m src.cli run \
+  --source local \
+  --directory "/path/to/emails" \
+  --output "/path/to/output" \
+  --no-llm-fallback
+
+# 2. Generate report
+python tools/generate_html_report.py \
+  --input "/path/to/output/results.json"
+```
+
+## results.json Format
+
+The report generator expects this structure:
+
+```json
+{
+  "metadata": {
+    "total_emails": 801,
+    "accuracy_estimate": 0.55,
+    "classification_stats": {
+      "rule_matched": 9,
+      "ml_classified": 468,
+      "llm_classified": 0,
+      "needs_review": 324
+    },
+    "generated_at": "2025-11-28T02:34:00.680196",
+    "source": "local",
+    "source_path": "/path/to/emails"
+  },
+  "classifications": [
+    {
+      "email_id": "unique_id.eml",
+      "subject": "Email subject line",
+      "sender": "sender@example.com",
+      "sender_name": "Sender Name",
+      "date": "2023-04-13T09:43:29+10:00",
+      "has_attachments": false,
+      "category": "Work",
+      "confidence": 0.81,
+      "method": "ml"
+    }
+  ]
+}
+```
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `email_id` | string | Unique identifier (usually filename) |
+| `subject` | string | Email subject line |
+| `sender` | string | Sender email address |
+| `category` | string | Assigned category |
+| `confidence` | float | Classification confidence (0-1) |
+| `method` | string | Classification method: `ml`, `rule`, or `llm` |
+
+### Optional Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `sender_name` | string | Display name of sender |
+| `date` | string | ISO 8601 date string |
+| `has_attachments` | boolean | Whether email has attachments |
+
+## Report Sections
+
+### 1. Header

+- Columns: Date, Subject, Sender, Category, Confidence, Method
+- Sorted by date (newest first)
+- Attachment indicator (📎)
+
+## Customization
+
+### Changing Colors
+
+Edit the CSS variables in `generate_html_report.py`:
+
+```css
+:root {
+    --bg-primary: #1a1a2e;      /* Main background */
+    --bg-secondary: #16213e;    /* Card backgrounds */
+    --bg-card: #0f3460;         /* Nested elements */
+    --text-primary: #eee;       /* Main text */
+    --text-secondary: #aaa;     /* Muted text */
+    --accent: #e94560;          /* Accent color (red) */
+    --accent-hover: #ff6b6b;    /* Accent hover */
+    --success: #00d9a5;         /* Green (high confidence) */
+    --warning: #ffc107;         /* Yellow (medium confidence) */
+    --border: #2a2a4a;          /* Border color */
+}
+```
+
+### Light Theme Example
+
+```css
+:root {
+    --bg-primary: #f5f5f5;
+    --bg-secondary: #ffffff;
+    --bg-card: #e8e8e8;
+    --text-primary: #333;
+    --text-secondary: #666;
+    --accent: #2563eb;
+    --accent-hover: #3b82f6;
+    --success: #10b981;
+    --warning: #f59e0b;
+    --border: #d1d5db;
+}
+```
+
+### Adding New Sections
+
+1. Add data extraction in `generate_html_report()` function
+2. Add HTML section in the main template string
+3. Style with existing CSS classes or add new ones
+
+### Adding New Table Columns
+
+1. Modify `generate_email_row()` function
+2. Add `<th>` in table header
+3. Add `<td>` in row template
+
+## Performance Notes
+
+- Report is fully static (no server required)
+- JavaScript is minimal (tab switching, search filtering)
+- Handles 1000+ emails without performance issues
+- For 10k+ emails, consider pagination (not yet implemented)
+
+## Future Enhancements (TODO)
+
+- [ ] Pagination for large datasets
+- [ ] Export to PDF option
+- [ ] Configurable color themes via CLI
+- [ ] Column sorting (click headers)
+- [ ] Date range filter
+- [ ] Sender domain grouping
+- [ ] Category confidence heatmap
+- [ ] Email body preview on hover
+
+## Troubleshooting
+
+### "KeyError: 'subject'"
+Results.json lacks email metadata. Re-run classification with latest cli.py.
+
+### Empty tables
+Check that results.json has `classifications` array with data.
+
+### Dates showing "N/A"
+Date parsing failed. Check date format in results.json is ISO 8601.
+
+### Search not working
+JavaScript error. Check browser console. Ensure no HTML entities in data.

+# Session Handover Report - Email Sorter
+**Date:** 2025-11-28
+**Session ID:** eb549838-a153-48d1-ae5d-891e0e83108f
+
+---
+
+## What Was Done This Session
+
+### 1. Classified 801 emails from brett-gmail using three methods:
+
+| Method | Accuracy | Time | Output Location |
+|--------|----------|------|-----------------|
+| ML-Only | 54.9% | ~5 sec | `/home/bob/Documents/Email Manager/emails/brett-gm-md/` |
+| ML+LLM | 93.3% | ~3.5 min | `/home/bob/Documents/Email Manager/emails/brett-gm-llm/` |
+| Manual Agent | 99.8% | ~25 min | Same as ML-only + analysis files |
+
+### 2. Created/Modified Files
+
+**New Files:**
+- `tools/generate_html_report.py` - HTML report generator
+- `tools/brett_gmail_analyzer.py` - Custom dataset analyzer
+- `data/brett_gmail_analysis.json` - Analysis output
+- `docs/REPORT_FORMAT.md` - Report system documentation
+- `docs/CLASSIFICATION_METHODS_COMPARISON.md` - Method comparison
+- `docs/PROJECT_ROADMAP_2025.md` - Full roadmap and learnings
+- `/home/bob/Documents/Email Manager/emails/brett-gm-md/BRETT_GMAIL_ANALYSIS_REPORT.md` - Analysis report
+- `/home/bob/Documents/Email Manager/emails/brett-gm-md/report.html` - HTML report (ML-only)
+- `/home/bob/Documents/Email Manager/emails/brett-gm-llm/report.html` - HTML report (ML+LLM)
+
+**Modified Files:**
+- `src/cli.py` - Added `--force-ml` flag, enriched results.json with email metadata
+- `src/llm/openai_compat.py` - Removed API key requirement for local vLLM
+- `config/default_config.yaml` - Changed LLM to openai provider on localhost:11433
+
+### 3. Key Configuration Changes
+
+```yaml
+# config/default_config.yaml - LLM now uses vLLM endpoint
+llm:
+  provider: "openai"
+  openai:
+    base_url: "http://localhost:11433/v1"
+    api_key: "not-needed"
+    classification_model: "qwen3-coder-30b"
+```
+
+---
+
+## Key Findings
+
+1. **ML pipeline overkill for <5000 emails** - Agent analysis gives better accuracy in similar time
+2. **Sender domain is strongest signal** - Top 5 senders = 47.5% of emails
+3. **Categories should serve downstream routing** - Not human labels, but processing decisions
+4. **Risk-based accuracy** - Personal emails need high accuracy, junk can tolerate errors
+5. **This tool = triage** - Sorts into buckets for other specialized tools
+
+---
+
+## Project Scope (Agreed with User)
+
+**Email Sorter IS:**
+- Bulk classification/triage tool
+- Router to downstream specialized tools
+- Part of larger email processing ecosystem
+
+**Email Sorter IS NOT:**
+- Complete email management solution
+- Spam filter (trust Gmail/Outlook)
+- Final destination for emails
+
+---
+
+## Recommended Dataset Size Routing
+
+| Size | Method |
+|------|--------|
+| <500 | Agent-only |
+| 500-5000 | Agent pre-scan + ML |
+| >5000 | ML pipeline |
+
+---
+
+## Background Processes
+
+There are stale background bash processes (f8678e, 0a3549, 0d150e) from classification runs. These completed successfully and can be ignored.
+
+---
+
+## What Needs Doing Next
+
+1. **Review docs/** - All learnings are in PROJECT_ROADMAP_2025.md
+2. **Phase 1 development** - Dataset size routing, sender-first classification
+3. **Agent pre-scan module** - 10-15 min discovery phase before ML
+
+---
+
+## User Preferences (from CLAUDE.md)
+
+- NO emojis in commits
+- NO "Generated with Claude" attribution
+- Use tools (Read/Edit/Grep) not bash commands for file ops
+- Virtual environment required for Python
+- TTS available via `fss-speak` (single line messages only, no newlines)
+
+---
+
+## Quick Start for Next Agent
+
+```bash
+cd /MASTERFOLDER/Tools/email-sorter
+source venv/bin/activate
+
+# Read the roadmap
+cat docs/PROJECT_ROADMAP_2025.md
+
+# Run classification
+python -m src.cli run --source local \
+  --directory "/path/to/emails" \
+  --output "/path/to/output" \
+  --force-ml --llm-provider openai
+
+# Generate HTML report
+python tools/generate_html_report.py --input /path/to/results.json

+# Email Sorter - Supplementary Tools
+
+This directory contains **optional** standalone tools that complement the main ML classification pipeline without interfering with it.
+
+## Tools
+
+### batch_llm_classifier.py
+
+**Purpose**: Ask custom questions across batches of emails using vLLM server
+
+**Prerequisite**: vLLM server must be running at configured endpoint
+
+**When to use this:**
+- One-off batch analysis with custom questions
+- Exploratory queries ("find all emails mentioning budget cuts")
+- Custom classification criteria not in trained ML model
+- Quick ad-hoc analysis without retraining
+
+**When to use RAG instead:**
+- Searching across large email corpus (10k+ emails)
+- Finding specific topics/keywords with semantic search
+- Building knowledge base from email content
+- Multi-step reasoning across many documents
+
+**When to use main ML pipeline:**
+- Regular ongoing classification of incoming emails
+- High-volume processing (100k+ emails)
+- Consistent categories that don't change
+- Maximum speed (pure ML with no LLM calls)
+
+---
+
+## batch_llm_classifier.py Usage
+
+### Check vLLM Server Status
+
+```bash
+python tools/batch_llm_classifier.py check
+```
+
+Expected output:
+```
+✓ vLLM server is running and ready
+✓ Max concurrent requests: 4
+✓ Estimated throughput: ~4.4 emails/sec
+```
+
+### Ask Custom Question
+
+```bash
+python tools/batch_llm_classifier.py ask \
+  --source enron \
+  --limit 100 \
+  --question "Does this email contain any financial numbers or budget information?" \
+  --output financial_emails.txt
+```
+
+**Parameters:**
+- `--source`: Email provider (gmail, enron)
+- `--credentials`: Path to credentials (for Gmail)
+- `--limit`: Number of emails to process
+- `--question`: Custom question to ask about each email
+- `--output`: Output file for results
+
+### Example Questions
+
+**Finding specific content:**
+```bash
+--question "Is this email about a meeting or calendar event? Answer yes/no and provide date if found."
+```
+
+**Sentiment analysis:**
+```bash
+--question "What is the tone of this email? Professional/Casual/Urgent/Friendly?"
+```
+
+**Categorization with custom criteria:**
+```bash
+--question "Should this email be archived or kept for reference? Explain why."
+```
+
+**Data extraction:**
+```bash
+--question "Extract all names, dates, and dollar amounts mentioned in this email."
+```
+
+---
+
+## Configuration
+
+vLLM server settings are in `batch_llm_classifier.py`:
+
+```python
+VLLM_CONFIG = {
+    'base_url': 'https://rtx3090.bobai.com.au/v1',
+    'api_key': 'rtx3090_foxadmin_10_8034ecb47841f45ba1d5f3f5d875c092',
+    'model': 'qwen3-coder-30b',
+    'batch_size': 4,  # Tested optimal - 100% success rate
+    'temperature': 0.1,
+    'max_tokens': 500
+}
+```
+
+**Note**: `batch_size: 4` is the tested optimal setting. Uses proper batch pooling (send 4, wait for completion, send next 4). Higher values cause 503 errors.
+
+---
+
+## Performance Benchmarks
+
+Tested on rtx3090.bobai.com.au with qwen3-coder-30b:
+
+| Emails | Batch Size | Time | Throughput | Success Rate |
+|--------|-----------|------|------------|--------------|
+| 500    | 4 (pooled)| 108s | 4.65/sec   | 100%         |
+| 500    | 8 (pooled)| 62s  | 8.10/sec   | 60%          |
+| 500    | 20 (pooled)| 23s | 21.8/sec   | 23%          |
+
+**Conclusion**: batch_size=4 with proper batch pooling is optimal (100% reliability, ~4.7 req/sec)
+
+---
+
+## Architecture Notes
+
+### Prompt Caching Optimization
+
+Prompts are structured with static content first, variable content last:
+
+```
+STATIC (cached):
+  - System instructions
+  - Question
+  - Output format guidelines
+
+VARIABLE (not cached):
+  - Email subject
+  - Email sender
+  - Email body
+```
+
+This allows vLLM to cache the static portion across all emails in the batch.
+
+### Separation from Main Pipeline
+
+This tool is **completely independent** from the main classification pipeline:
+
+- **Main pipeline** (`src/cli.py run`):
+  - Uses calibrated LightGBM model
+  - Fast pure ML classification
+  - Optional LLM fallback for low-confidence cases
+  - Processes 10k emails in ~24s (pure ML) or ~5min (with LLM fallback)
+
+- **Batch LLM tool** (`tools/batch_llm_classifier.py`):
+  - Uses vLLM server exclusively
+  - Custom questions per run
+  - ~4.4 emails/sec throughput
+  - For ad-hoc analysis, not production classification
+
+### No Interference Guarantee
+
+The batch LLM tool:
+- ✓ Does NOT modify any files in `src/`
+- ✓ Does NOT touch trained models in `src/models/`
+- ✓ Does NOT affect config files
+- ✓ Does NOT interfere with existing workflows
+- ✓ Uses separate vLLM endpoint (not Ollama)
+
+---
+
+## Comparison: Batch LLM vs RAG
+
+| Feature | Batch LLM (this tool) | RAG (rag-search) |
+|---------|----------------------|------------------|
+| **Speed** | 4.4 emails/sec | Instant (pre-indexed) |
+| **Flexibility** | Custom questions | Semantic search queries |
+| **Best for** | 50-500 email batches | 10k+ email corpus |
+| **Prerequisite** | vLLM server running | RAG collection indexed |
+| **Use case** | "Does this mention X?" | "Find all emails about X" |
+| **Reasoning** | Per-email LLM analysis | Similarity + ranking |
+
+**Rule of thumb:**
+- < 500 emails + custom question = Use Batch LLM
+- > 1000 emails + topic search = Use RAG
+- Regular classification = Use main ML pipeline
+
+---
+
+## Prerequisites
+
+1. **vLLM server must be running**
+   - Endpoint: https://rtx3090.bobai.com.au/v1
+   - Model loaded: qwen3-coder-30b
+   - Check with: `python tools/batch_llm_classifier.py check`
+
+2. **Python dependencies**
+   ```bash
+   pip install httpx click
+   ```
+
+3. **Email provider setup**
+   - Enron: No setup needed (uses local maildir)
+   - Gmail: Requires credentials file
+
+---
+
+## Troubleshooting
+
+### "vLLM server not available"
+
+Check server status:
+```bash
+curl https://rtx3090.bobai.com.au/v1/models \
+  -H "Authorization: Bearer rtx3090_foxadmin_10_8034ecb47841f45ba1d5f3f5d875c092"
+```
+
+Verify model is loaded:
+```bash
+python tools/batch_llm_classifier.py check
+```
+
+### High error rate (503 errors)
+
+Reduce concurrent requests in `VLLM_CONFIG`:
+```python
+'max_concurrent': 2,  # Lower if getting 503s
+```
+
+### Slow processing
+
+- Check vLLM server isn't overloaded
+- Verify network latency to rtx3090.bobai.com.au
+- Consider using main ML pipeline for large batches
+
+---
+
+## Future Enhancements
+
+Potential additions (not implemented):
+
+- Support for custom prompt templates
+- JSON output mode for structured extraction
+- Progress bar for large batches
+- Retry logic for transient failures
+- Multi-server load balancing
+- Streaming responses for real-time feedback
+
+---
+
+**Remember**: This tool is supplementary. For production email classification, use the main ML pipeline (`src/cli.py run`).
