Cache on Cloud is not properly working

What version of Codex is running?

Codex Cloud

Which model were you using?

_No response_

What platform is your computer?

Ubuntu

What steps can reproduce the bug?

Every time I run a prompt, the machine re-executes the full setup instead of using the cached environment. Setup is executed on every run, causing slow start times and unnecessary resource usage.

What is the expected behavior?

If I run a task without any setup configuration changes and less than 12 hours have passed since the last task, the environment should run the maintenance script only (reuse cache) rather than executing the full setup.

What do you see instead?

the setup is loaded (with all the installations)
