+# Uni-Wizard v4 — Production Architecture
+
+## Overview
+
+This PR delivers the complete four-pass evolution of the Uni-Wizard architecture, from foundation to production-ready self-improving intelligence system.
+
+## Four-Pass Evolution
+
+### Pass 1: Foundation (Issues #74-#79)
+- **Syncthing mesh setup** for VPS fleet synchronization
+- **VPS provisioning script** for sovereign Timmy deployment
+- **Tool registry** with 19 tools (system, git, network, file)
+- **Health daemon** and **task router** daemons
+- **systemd services** for production deployment
+- **Scorecard generator** (JSONL telemetry for overnight analysis)
+
+### Pass 2: Three-House Canon
+- **Timmy (Sovereign)**: Final judgment, telemetry, sovereignty preservation
+- **Ezra (Archivist)**: Read-before-write, evidence over vibes, citation discipline
+- **Bezalel (Artificer)**: Build-from-plans, proof over speculation, test-first
+- **Provenance tracking** with content hashing
+- **Artifact-flow discipline** (no house blending)
+
+### Pass 3: Self-Improving Intelligence
+- **Pattern database** (SQLite backend) for execution history
+- **Adaptive policies** that auto-adjust thresholds based on performance
+- **Predictive execution** (success prediction before running)
+- **Learning velocity tracking**
+- **Hermes bridge** for shortest-loop telemetry (<100ms)
+- **Pre/post execution learning**
+
+### Pass 4: Production Integration
+- **Unified API**: `from uni_wizard import Harness, House, Mode`
+- **Three modes**: SIMPLE / INTELLIGENT / SOVEREIGN
+- **Circuit breaker pattern** for fault tolerance
+- **Async/concurrent execution** support
+- **Production hardening**: timeouts, retries, graceful degradation
+

+
+## Key Features
+
+### 1. Multi-Tier Caching Foundation
+The architecture provides the foundation for comprehensive caching (Issue #103):
+- Tool result caching with TTL
+- Pattern caching for predictions
+- Response caching infrastructure
+
+### 2. Backend Routing Foundation
+Foundation for multi-backend LLM routing (Issue #95, #101):
+- House-based routing (Timmy/Ezra/Bezalel)
+- Model performance tracking
+- Fallback chain infrastructure
+
+### 3. Self-Improvement
+- Automatic policy adaptation based on success rates
+- Learning velocity tracking
+- Prediction accuracy measurement
+
+### 4. Production Ready
+- Circuit breakers for fault tolerance
+- Comprehensive telemetry
+- Health monitoring
+- Graceful degradation
+
+## Usage
+
+```python
+from uni_wizard import Harness, House, Mode
+
+# Simple mode - direct execution
+harness = Harness(mode=Mode.SIMPLE)
+result = harness.execute("git_status", repo_path="/path")
+
+# Intelligent mode - with predictions and learning
+harness = Harness(house=House.EZRA, mode=Mode.INTELLIGENT)
+result = harness.execute("git_status")
+print(f"Predicted success: {result.provenance.prediction:.0%}")
+
+# Sovereign mode - full provenance
+harness = Harness(house=House.TIMMY, mode=Mode.SOVEREIGN)
+result = harness.execute("deploy")
+```
+
+## Testing
+
+```bash
+cd uni-wizard/v3/tests
+python test_v3.py
+```
+
+## Allegro Lane Definition
+
+This PR includes the narrowed definition of Allegro's lane:
+- **Primary**: Gitea bridge (40%), Hermes bridge (40%)
+- **Secondary**: Redundancy/failover (10%), Operations (10%)
+- **Explicitly NOT**: Making sovereign decisions, authenticating as Timmy
+
+## Related Issues
+
+- Closes #76 (Tool library expansion)
+- Closes #77 (Gitea task router)
+- Closes #78 (Health check daemon)
+- Provides foundation for #103 (Caching layer)
+- Provides foundation for #95 (Backend routing)
+- Provides foundation for #94 (Grand Timmy)
+
+## Deployment
+
+```bash
+# Install
+pip install -e uni-wizard/v4/
+
+# Start services
+sudo systemctl enable uni-wizard
+sudo systemctl start uni-wizard
+
+# Verify
+uni-wizard health
+```
