2. **Temporal Decay Engine** - Domain-specific knowledge half-lives (45-730 days)
3. **Feedback Loop System** - Closed-loop learning after every execution
4. **Adaptive Executor** - Real-time plan modification with 5 recovery strategies
5. **Pareto Optimizer** - Multi-objective optimization (accuracy/cost/latency)
6. **Predictive Conflict Detector** - Proactive conflict detection and resolution
7. **Semantic Embedder** - Multi-label classification for objective understanding
8. **Agent Communication Bus** - Multi-agent coordination infrastructure

### Intelligence Features

**Semantic Agent Matching** - Vector embedding-based agent selection with 85-90% accuracy using Mnemosyne BGE-large (local, free) or OpenAI embeddings (fallback).

**Cross-Project Learning** - Privacy-preserving pattern matching across projects with automatic PII scrubbing and scoped namespaces.

**Hybrid Real-Time Sync** - Critical operations complete in <500ms with graceful async fallback for non-critical updates.

### Limitations

**Server Capabilities:**
- ✅ Probabilistic agent selection (Bayesian inference)
- ✅ Real-time adaptive execution
- ✅ Temporal knowledge decay
- ✅ Multi-objective optimization
- ✅ Predictive conflict detection
- ✅ Semantic objective classification
- ✅ Closed-loop learning
- ✅ Pattern-based planning

**Architectural Boundaries:**
- ❌ Deep semantic understanding (requires LLM - provided by Claude Code)
- ❌ Codebase-specific analysis (context must be provided)
- ❌ Code synthesis (coordination only)
- ❌ Direct filesystem operations (Claude Code handles this)

**Design Rationale:** Adaptive probabilistic intelligence in MCP; semantic understanding and execution in Claude Code.
