The read deadline only gets control at a read, so code that computes without reading escaped it. Give the pool a request_timeout above code_timeout. The watchdog kills the worker, and execute() already replaces a dead session, so a runaway call fails and the next call recovers. A read refusal keeps the variables, so it has to win the race whenever code does read. Restore test_open_file_objects_are_not_iterable. Replacing the neighbouring write test by text range deleted it, which left the instructions carrying a prohibition with nothing to signal when monty lifts it. Reuse the VFS and the pool when a session is replaced, so recovery skips the document scan. Mount metadata.json with a lambda rather than a factory. Cover open() in write mode. Fold the crash entry into the pydantic-monty bullet, because no release shipped the worker without it.
