-  - `src/app/app.cmake` (yaze GUI target, both macOS and Windows/Linux)

 ## Technical Details
 
+### Conditional Compilation
+
+The policy framework uses conditional compilation to allow building without policy support:
+
+```cpp
+#ifdef YAZE_ENABLE_POLICY_FRAMEWORK
+  auto& policy_eval = cli::PolicyEvaluator::GetInstance();
+  auto policy_result = policy_eval.EvaluateProposal(p.id);
+  // ... policy evaluation logic ...
+#endif
+```
+
+**Build Targets**:
+- `yaze` (main editor): Policy framework **enabled** ✅
+- `yaze_emu` (emulator): Policy framework **disabled** (not needed)
+- `z3ed` (CLI): Policy framework **enabled** ✅
+
 ### API Usage Patterns

 2. **StatusOr API**: Used `.ok()` and `.value()` instead of `.has_value()`
 3. **String Numbers**: Added `#include "absl/strings/numbers.h"` for SimpleAtoi
 4. **String View**: Explicit `std::string()` cast for all absl::StripAsciiWhitespace() calls
+5. **Conditional Compilation**: Wrapped policy code with `YAZE_ENABLE_POLICY_FRAMEWORK` to fix yaze_emu build
