+### 2. ~~Inconsistent Error Handling in CLI Runner~~ ✅ RESOLVED
 
 **File:** [src/cli/runner.ts](../src/cli/runner.ts#L96-L101)  
-**Severity:** Medium  
-**Issue:** Error handling logic has unreachable code and inconsistent behavior.
-
-**Current Code:**
-```typescript
-try {
-  await command.run(argv.slice(1))
-} catch (err) {
-  if (err instanceof CommandError) {
-    error(err.message, err.exitCode)  // Calls process.exit()
-  }
-  
-  throw err  // Unreachable for CommandError, unhandled for other errors
-}
-```
-
-**Problem:**
-- The `error()` function calls `process.exit()`, making `throw err` unreachable for `CommandError` instances
-- Non-`CommandError` errors are re-thrown without proper handling
-- Inconsistent error reporting
+**Status:** ✅ **RESOLVED**  
+**Resolution:** Error handling now includes proper `return` statement after calling `error()`, and non-CommandError errors are properly re-thrown.
 
-**Recommended Fix:**
+**Current Implementation:**
 ```typescript
 try {
   await command.run(argv.slice(1))
 } catch (err) {
   if (err instanceof CommandError) {
     error(err.message, err.exitCode)
+    return
   }
   
-  // Handle unexpected errors
-  console.error('Unexpected error:', err)
-  process.exit(ExitCode.GENERAL_ERROR)
+  throw err  // Re-throw non-CommandError errors
 }
 ```
 
-**Impact:** Better error handling and consistent exit behavior.

+The codebase is in excellent shape with only minor improvements suggested. One critical issue has been resolved since the last review. The primary focus should be on:
+
+1. ✅ Ensuring all files have proper license headers
 2. Improving type safety where assertions are used
-3. Adding documentation for public APIs
+3. Deciding on exit code behavior for partial failures
+4. Adding documentation for public APIs
 
 No breaking changes are necessary. All improvements can be implemented incrementally without disrupting existing functionality.
