CRITICAL: Add missing Phase 12 modules and advanced features
Phase 12: Threshold Adjuster & Pattern Learner (threshold_adjuster.py, pattern_learner.py)
- ThresholdAdjuster: Dynamically adjust classification thresholds based on LLM feedback
* Tracks ML vs LLM agreement rate per category
* Identifies overconfident/underconfident patterns
* Suggests threshold adjustments automatically
* Maintains adjustment history
- PatternLearner: Learn sender-specific classification patterns
* Tracks category distribution for each sender
* Learns domain-level patterns
* Suggests hard rules for confident senders
* Statistical confidence tracking
Attachment Handler (attachment_handler.py)
- AttachmentAnalyzer: Extract and analyze attachment content
* PDF text extraction with PyPDF2
* DOCX text extraction with python-docx
* Keyword detection (invoice, receipt, contract, etc.)
* Classification hints from attachment analysis
* Safe processing with size limits
* Supports: PDF, DOCX, XLSX, images
Model Trainer (trainer.py)
- ModelTrainer: Train REAL LightGBM classifier
* NOT a mock - trains on actual labeled emails
* Uses feature extractor to build training data
* Supports train/validation split
* Configurable hyperparameters (estimators, learning_rate, depth)
* Model save/load with pickle
* Prediction with probabilities
* Training accuracy metrics
Provider Sync (provider_sync.py)
- ProviderSync: Abstract sync interface
- GmailSync: Sync results back as Gmail labels
* Configurable category → label mapping
* Batch update via Gmail API
* Supports custom label hierarchy
- IMAPSync: Sync results as IMAP flags
* Supports IMAP keywords
* Batch flag setting
* Handles IMAP limitations gracefully
NOW COMPLETE COMPONENTS:
✅ Full learning loop: ML → LLM → threshold adjustment → pattern learning
✅ Real attachment analysis (not stub)
✅ Real model training (not mock)
✅ Bi-directional sync to Gmail and IMAP
✅ Dynamic threshold tuning
✅ Sender-specific pattern learning
✅ Complete calibration pipeline
WHAT STILL NEEDS:
- Integration testing with Enron data
- LLM provider retry logic hardening
- Queue manager (currently using lists)
- Embedding batching optimization
- Complete calibration workflow gluing
