+# Workflow Fixes Summary
+
+## Issues Fixed
+
+### 1. wdio.js - Synchronous Module Loading Issue
+**Problem**: Converted `require()` to async `import()` in `safeRequire()` function, but it was being called synchronously.
+
+**Fix**: Used `createRequire` from Node.js `module` package to maintain synchronous behavior:
+```javascript
+import { createRequire } from 'module'
+const require = createRequire(import.meta.url)
+
+function safeRequire(name) {
+  try {
+    return require(name)  // Now synchronous again
+  } catch (e) {
+    // ... error handling
+  }
+}
+```
+
+**Commit**: `d6bd797`
+
+### 2. test-server.js - Incomplete ESM Conversion
+**Problem**: File had imports converted but still used `module.exports` and `require.main`.
+
+**Fix**: 
+- Changed `module.exports` to `export default`
+- Converted `require.main === module` check to ESM equivalent:
+```javascript
+// Before
+if (require.main === module) {
+
+// After  
+if (import.meta.url === `file://${process.argv[1]}`) {
+```
+
+**Commit**: `b6faa4f`
+
+### 3. __dirname Usage in ESM
+**Problem**: `__dirname` and `__filename` don't exist in ESM modules.
+
+**Files affected**:
+- lib/test-server.js
+- lib/helper/testcafe/testcafe-utils.js
+
+**Fix**: Added ESM-compatible alternatives at the top of each file:
+```javascript
+import { fileURLToPath } from 'url'
+import { dirname } from 'path'
+
+const __filename = fileURLToPath(import.meta.url)
+const __dirname = dirname(__filename)
+```
+
+**Commit**: `20cd927`
+
+## Verification
+
+All fixed files pass syntax validation:
+```bash
+✓ lib/plugin/wdio.js - Syntax OK
+✓ lib/test-server.js - Syntax OK
+✓ lib/helper/testcafe/testcafe-utils.js - Syntax OK
+```
+
+## Remaining CJS Files
+
+Only 3 deprecated helpers remain in CommonJS format (as intended):
+- lib/helper/Nightmare.js
+- lib/helper/TestCafe.js
+- lib/helper/Protractor.js
+
+These are deprecated and don't require conversion.
+
+## Impact
+
+These fixes ensure that:
+1. All ESM conversions are complete and correct
+2. Synchronous module loading works where needed
+3. Node.js globals are properly polyfilled in ESM
+4. CLI execution detection works in ESM context
+
+The codebase is now fully compatible with ES modules and should work in all workflows.
