## Title

    Proposed fix: [AWS Lambda Python] 'Runtime.ImportModuleError: Unable to import module 'lambda_function': No module named 'lambda_function'' / 'Runtime.HandlerNotFound: Handler 'x' missing on module' —

## Body

    Recommended action: Zip the file contents (not the parent folder) so lambda_function.py is at the root, or set Handler to pkg/module.func; ensure the function name matches; don't name the handler module after a built-in (e.g. sys).
    
    Option: Fix the zip layout / Handler [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. cd package_dir && zip -r ../function.zip .
    2. unzip -l function.zip | head  # lambda_function.py at root
    3. Handler = lambda_function.lambda_handler
    Expected: Command proceeds without the error.
    
    Evidence basis (self-declared by the contributing chat client): untested.
