No repository file, test, or entry point is named in the issue. Start by reproducing the Azure portal sequence: rotate the storage key, update the Key Vault secret, and observe the Function App and JobHostStopped traces. Done means the app retrieves the updated AzureWebJobsStorage value and can restart or stop normally.
