The recovery branch (Failed execution → CleanupStaleExecutionBySessionID
→ relaunch) is the load-bearing piece of shell session resilience and
had no direct test. Extract the body into a free function that takes a
narrow shellLifecycle interface so the four branches are testable
without standing up a real lifecycle.Manager:
- happy path (running execution, no cleanup)
- stale recovery (Failed → cleanup → fresh)
- initial GetOrEnsureExecution failure
- cleanup failure must NOT trigger a re-launch loop
- relaunch failure surfaces a clear "recover execution" error
