Start by reproducing FunctionPullingContainerPoolTests and the listed ActionsApiTests failures, then inspect the failing assertions and surrounding test setup. Trace the affected container-pool and Actions API entry points to determine whether the failures share a cause. Done means the named tests pass, including warmed-container retry and acknowledgment behavior and the listed action retrieval cases.
