Feature Summary

1. Semantic Embeddings (P0 - HIGH IMPACT)

Implementation: core/embeddings.py

• Uses sentence-transformers (all-MiniLM-L6-v2 model)
• Pre-computed exemplar embeddings for 10 document types
• Cosine similarity-based classification
• Graceful fallback to keyword matching when model unavailable
• Embedding cache for efficiency

Expected Impact: +15-25% accuracy on ambiguous documents

2. Historical Learning Loop (P0 - HIGH IMPACT)

Implementation: core/learning.py

• SQLite-backed persistence (moe_learning.db)
• Records all classification outcomes
• Tracks analyst accuracy per document type
• Dynamic weight calculation based on performance
• Bootstrap from existing frontmatter-typed documents
• Confirmation workflow for feedback loop

Expected Impact: Self-improving system over time

3. Memory System Integration (P1 - MEDIUM IMPACT)

Implementation: core/memory_integration.py

• Integrates with CODITECT context.db
• Finds similar documents from session history
• Extracts project-specific conventions
• Provides classification hints from memory

Expected Impact: Leverages 584MB of historical context

4. Adaptive Thresholds (P1 - MEDIUM IMPACT)

Implementation: core/adaptive_thresholds.py

• Self-tuning based on escalation/accuracy rates
• Target: 10% escalation rate, 90% accuracy
• Automatic threshold adjustment every 100 classifications
• Persisted state with adjustment history

Expected Impact: -30% unnecessary escalations

5. Confidence Calibration (P1 - HIGH IMPACT)

Implementation: core/calibration.py

• Validates confidence scores against actual accuracy
• 10-bin calibration curve
• Expected Calibration Error (ECE) calculation
• Histogram-based confidence adjustment

Expected Impact: 90% confidence = 90% accuracy

6. Additional Judges (P2 - MEDIUM IMPACT)

Implementation: judges/frontmatter_judge.py, judges/directory_judge.py, judges/historical_judge.py

• FrontmatterJudge: Veto authority, validates explicit declarations
• DirectoryJudge: Advisory, checks directory conventions
• HistoricalJudge: Advisory, compares historical patterns

Expected Impact: +3 validation layers

7. Batch Corpus Analysis (P2 - LOW IMPACT)

Implementation: core/batch_processor.py

• Corpus profiling (type distribution, directories)
• Document clustering by directory/pattern
• Cross-document consistency checking
• Parallel classification with ThreadPoolExecutor

Expected Impact: Corpus-level optimization

Usage Guide

Initialize Enhanced System

from H.P.004-SCRIPTS.moe_classifier.core.enhanced_orchestrator import get_enhanced_orchestrator

orchestrator = get_enhanced_orchestrator()
stats = orchestrator.get_stats()

Get Pre-Classification Hints

from H.P.004-SCRIPTS.moe_classifier.core.models import Document

doc = Document.from_path("path/to/file.md")
hints = orchestrator.get_pre_classification_hints(doc)
# hints = {'embedding_suggestion': 'guide', 'memory_suggestion': 'guide', ...}

Train from Confirmations

# Via command
/moe-learn --confirm docs/guides/SETUP.md guide

# Via Python
from H.P.004-SCRIPTS.moe_classifier.core.learning import get_learner
learner = get_learner()
learner.confirm_classification("docs/guides/SETUP.md", "guide")

Check Calibration Status

/moe-calibrate --status
/moe-calibrate --curve
/moe-calibrate --analysts

Bootstrap from Existing Documents

/moe-learn --bootstrap docs/

Next Steps

Immediate (Post-Implementation)

1. ✅ Run /classify on new documentation files
2. ⏸️ Bootstrap learning from existing typed documents
3. ⏸️ Monitor calibration curve development
4. ⏸️ Track analyst performance metrics

Short-Term (1-2 Weeks)

1. Accumulate 100+ confirmed classifications
2. Validate calibration curve accuracy
3. Fine-tune threshold targets
4. Add more exemplars to embeddings

Long-Term (1+ Months)

1. Implement vector database for embeddings (replace in-memory)
2. Add ensemble model support
3. Create web UI for calibration dashboard
4. Integrate with CI/CD for auto-classification
