Context Manager Code

EPAM India QA automation code often needs a resource lifecycle that behaves consistently when an operation succeeds or raises an exception. Implement execute_session(actions) using a Python context manager.

The context manager must record lifecycle events in this order:

1. Append "acquire" when the session starts.
2. Execute each action in actions, appending ordinary action names to the event log.
3. If an action equals "fail", raise a ValueError and do not append "fail".
4. Append "commit" only when every action completes successfully.
5. Append "rollback" when any exception occurs.
6. Append "release" exactly once in all cases, including failures.
7. Handle the deliberate ValueError inside execute_session and return the event log. Do not suppress exceptions inside the context manager itself.

Formal Specification

• Input: actions, a list of strings containing ordinary action names and optionally one "fail" action.
• Output: A list of strings describing the lifecycle events.
• The input contains at most one "fail" action.
