+# Test Event Fixes - Complete
+
+**Date**: 2025-12-24  
+**Status**: ✅ All test event emission errors fixed
+
+---
+
+## ✅ Fixed Test Files
+
+### Issue
+Tests were trying to emit events from interfaces or abstract contracts, which is not allowed in Solidity. Events can only be emitted from concrete contract instances.
+
+### Solution
+Added helper event definitions in each test contract that match the interface/abstract contract event signatures, then updated emit statements to use the helper events.
+
+---
+
+## 📋 Files Fixed
+
+### 1. CompliantUSDTTest.t.sol
+- **Issue**: `emit LegallyCompliantBase.ValueTransferDeclared(...)`
+- **Fix**: Added helper event `ValueTransferDeclared` in test contract
+- **Status**: ✅ Fixed
+
+### 2. AccountWalletRegistryTest.t.sol
+- **Issue**: `emit IAccountWalletRegistry.AccountWalletLinked(...)` and `AccountWalletUnlinked(...)`
+- **Fix**: Added helper events `AccountWalletLinked` and `AccountWalletUnlinked`
+- **Status**: ✅ Fixed
+
+### 3. RailEscrowVaultTest.t.sol
+- **Issue**: `emit IRailEscrowVault.Locked(...)` and `Released(...)`

+## ✅ Verification
