+# Policy Evaluation Framework (AW-04)
+
+**Status**: Implementation In Progress  
+**Priority**: High (Next Phase)  
+**Time Estimate**: 6-8 hours  
+**Last Updated**: October 2, 2025
+
+## Overview
+
+The Policy Evaluation Framework provides a YAML-based constraint system for gating proposal acceptance in the z3ed agent workflow. It ensures that AI-generated ROM modifications meet quality, safety, and testing requirements before being merged into the main ROM.
+
+## Goals
+
+1. **Quality Gates**: Enforce minimum test pass rates and code quality standards
+2. **Safety Constraints**: Prevent modifications to critical ROM regions (headers, checksums)
+3. **Scope Limits**: Restrict changes to reasonable byte counts and specific banks
+4. **Human Review**: Require manual review for large or complex changes
+5. **Flexibility**: Allow policy overrides with confirmation and logging
+
+## Architecture

+### Phase 2: Policy Evaluation Logic (2-3 hours)
+
+Implement the core evaluation methods that check proposals against each policy type.
+
+### Phase 3: GUI Integration (2 hours)
+
+#### 3.1 Update ProposalDrawer
+
+**File**: `src/app/editor/system/proposal_drawer.cc`
+
+Add policy status display and gating logic:

+```
+
+### Phase 4: Testing & Documentation (1-2 hours)
+
+#### 4.1 Example Policy File
+
+Create `.yaze/policies/agent.yaml.example`:
+
+```yaml
+# Example agent policy configuration
+# Copy to .yaze/policies/agent.yaml and customize
+
+version: 1.0
+enabled: true
+
+policies:
+  # Require test suites to pass
+  - name: require_tests
+    type: test_requirement
+    enabled: false  # Disabled by default (no tests yet)
+    severity: critical

+        reason: "ROM header"
+    message: "Cannot modify ROM header"
+```
+
+#### 4.2 Unit Tests
+
+Create `test/cli/policy_evaluator_test.cc`:
+
+```cpp
+#include "src/cli/service/policy_evaluator.h"
+#include "gtest/gtest.h"
+
+namespace yaze {
+namespace cli {
+namespace {
+
+TEST(PolicyEvaluatorTest, LoadPoliciesSuccess) {

+  auto status = eval.LoadPolicies("test/fixtures/policies");
+  EXPECT_TRUE(status.ok());
+  EXPECT_TRUE(eval.IsEnabled());
+}
+
+TEST(PolicyEvaluatorTest, EvaluateProposal_NoViolations) {
+  // ... test implementation
+}
+
+TEST(PolicyEvaluatorTest, EvaluateProposal_CriticalViolation) {
+  // ... test implementation
+}
+
+}  // namespace
+}  // namespace cli
+}  // namespace yaze
+```

 - **Priority 1**: Complete E2E Validation by implementing identified fixes for window detection and thread safety.
 - **Priority 2**: Begin Policy Evaluation Framework (AW-04) - a YAML-based constraint system for proposal acceptance.
 
-**Recent Accomplishments**:
-- **gRPC Test Harness (IT-01 & IT-02)**: Core implementation of all 6 RPCs (Ping, Click, Type, Wait, Assert, Screenshot) is complete, enabling automated GUI testing from natural language prompts.
-- **Root Cause Analysis**: Identified key sources of test flakiness, including a window-creation timing issue and a thread-safety bug in RPC handlers. Solutions have been designed.
-- **Build System**: Hardened the CMake build for reliable gRPC integration.
-- **Proposal Workflow**: The agentic proposal system (create, list, diff, review in GUI) is fully operational.
+**Recent Accomplishments** (Updated: October 2, 2025):
+- **✅ E2E Validation Complete**: All 5 functional RPC tests passing (Ping, Click, Type, Wait, Assert)
+  - Window detection timing issue **resolved** with 10-frame yield buffer in Wait RPC
+  - Thread safety issues **resolved** with shared_ptr state management
+  - Test harness validated on macOS ARM64 with real YAZE GUI interactions
+- **gRPC Test Harness (IT-01 & IT-02)**: Full implementation complete with natural language → GUI testing
+- **Build System**: Hardened CMake configuration with reliable gRPC integration
+- **Proposal Workflow**: Agentic proposal system fully operational (create, list, diff, review in GUI)
 
-**Known Issues**:
-- **Test Flakiness**: The e2e test script (`test_harness_e2e.sh`) is flaky due to a timing issue where `Click` actions that open new windows return before the window is interactable.
-  - **Solution**: The `Click` RPC handler must call `ctx->Yield()` after performing the click to allow the ImGui frame to update before the RPC returns.
-- **RPC Handler Crashes**: The `Wait` and `Assert` RPCs can crash due to unsafe state sharing between the gRPC thread and the test engine thread.
-  - **Solution**: A thread-safe pattern using a `std::shared_ptr` to a state struct must be implemented for these handlers.
-- **Screenshot RPC**: The Screenshot RPC is a non-functional stub.
+**Known Limitations** (Non-Blocking):
+- **Screenshot RPC**: Stub implementation (returns "not implemented" - planned for production phase)
+- **Widget Naming**: Documentation needed for icon prefixes and naming conventions
+- **Performance**: Tests add ~166ms per Wait call due to frame yielding (acceptable trade-off)

 # z3ed: AI-Powered CLI for YAZE
 
-**Status**: Active Development  
-**Version**: 0.1.0-alpha  
-**Last Updated**: October 2, 2025 (E2E Validation 80% Complete)
+**Status**: Active Development
 
 ## Overview
 
-z3ed is a command-line interface for YAZE that enables AI-driven ROM modifications through a proposal-based workflow. It provides both human-accessible commands and machine-readable APIs for LLM integration.
+`z3ed` is a command-line interface for YAZE that enables AI-driven ROM modifications through a proposal-based workflow. It provides both human-accessible commands for developers and machine-readable APIs for LLM integration, forming the backbone of an agentic development ecosystem.

-# Basic build (without gRPC)
-cmake --build build --target z3ed -j8
+# Basic build (without GUI automation support)
+cmake --build build --target z3ed
