+# Documentation and Test Fixes
+
+**Date**: 2025-12-24  
+**Status**: ✅ Fixed
+
+---
+
+## ✅ Fixed Issues
+
+### 1. Documentation Tag Mismatches
+
+The `@return` tags in documentation didn't match the actual return parameter names after renaming.
+
+#### TransactionMirror.sol
+**Error**: `@return tx` but parameter is `mirroredTx`  
+**Fix**: Updated to `@return mirroredTx`
+
+#### OraclePriceFeed.sol
+**Error**: `@return needsUpdate` but parameter is `updateNeeded`  
+**Fix**: Updated to `@return updateNeeded`
+
+#### PriceFeedKeeper.sol
+**Error**: `@return needsUpdate` but parameter is `updateNeeded`  
+**Fix**: Updated to `@return updateNeeded`
+
+---
+
+### 2. Test Event Reference Error
+
+**Error**: `Member "ValueTransferDeclared" not found in type(contract CompliantUSDT)`
+
+**Issue**: The event `ValueTransferDeclared` is defined in `LegallyCompliantBase`, not directly in `CompliantUSDT`. Even though `CompliantUSDT` inherits from it, the test needs to reference it through the base contract.
+
+**Fix**: 
+1. Added import for `LegallyCompliantBase`
+2. Changed event reference from `CompliantUSDT.ValueTransferDeclared` to `LegallyCompliantBase.ValueTransferDeclared`
+
+```solidity
+// Before
+emit CompliantUSDT.ValueTransferDeclared(...);
+
+// After
+emit LegallyCompliantBase.ValueTransferDeclared(...);
+```

+
+## 📋 Files Modified
+
+1. `contracts/mirror/TransactionMirror.sol` - Fixed `@return` tag
+2. `contracts/reserve/OraclePriceFeed.sol` - Fixed `@return` tag
+3. `contracts/reserve/PriceFeedKeeper.sol` - Fixed `@return` tag
+4. `test/compliance/CompliantUSDTTest.t.sol` - Fixed event reference and added import
+
+---
+
+## ✅ Verification
+
+All documentation tags now match their return parameters, and the test should compile successfully.
