# Refactoring & Documentation Summary 🎯

## What Was Done

### 1. Architectural Refactoring ✅

**Problem:** TUI had domain logic mixed with presentation layer

**Solution:** Created clean service layer

**Files Created:**
- `app/services/policy_service.py` - Centralized policy operations

**Files Modified:**
- `app/policy_tui_textual.py` - Removed domain logic, now only handles UI

**Key Improvements:**
- ✅ Single source of truth for policy operations
- ✅ UI no longer interprets signal contracts
- ✅ Normalization only happens on load/save (not on every UI sync)
- ✅ Simulator and runtime share same evaluation path
- ✅ Easy to swap UI implementations (Textual → Web)

**Before:**
```python
# TUI doing domain logic
def _simulate_preview(self):
    simulator = PolicySimulator(normalize_policy_config(self.config))
    result = simulator.simulate(...)
    matched_signals = [...]  # UI parsing signals
    policy_matches = self._derive_policy_matches(...)  # UI logic
```

**After:**
```python
# TUI calling service layer
def _simulate_preview(self):
    result = PolicyService.simulate(self.config, text, role)
    explanation = PolicyService.explain_decision(result, self.config)
    # Just display the explanation
```
