GitHub Codespaces vs Local Dev Containers: postCreateCommand Idempotency

The objective is to guarantee that the postCreateCommand runs with identical state when the development environment is launched either through GitHub Codespaces or via a local Docker‑based Dev Container.

Because the execution context differs — cloud‑managed virtual machines versus the developer’s machine — the script may encounter non‑idempotent network calls or external service failures, leading to divergent outcomes. How does this environment affect the idempotency of postCreateCommand? What techniques can ensure consistent state when dependencies fail during the command execution? Can a single verification approach be applied across both execution modes?
