Package cleanup keeps a process-wide list of actions that must be undone when the process stops abruptly.

Package coordinator runs one bounded fan-out over the accounts and owns every child process that fan-out spawns.

Package fault makes otherwise unreachable failure branches reachable from tests.

Package lockorder witnesses one lock-order rule: an operation never takes the registry's configuration lock while it owns a Codex namespace guard.

Package logbuf decides where log output goes while the watch display owns the terminal.

Package proc asks the operating system about processes other than this one.

Package signals handles the termination signals.

Package tty answers what a command may do with its own terminal: whether a stream is one, how big it is, and bounded waits for input on it — never another process's input.
