A process execution library for the failure modes ProcessBuilder leaves to you. An alternative to zt-exec.

Outcomes you have to handle

Every run ends in a sealed ProcessOutcome, so a timeout or a crash is a type the compiler makes you deal with.

Pipes drained for you

stdout and stderr are read on virtual threads while the process runs, so a chatty child can’t deadlock its parent.

No orphaned grandchildren

Stopping a process reaps the whole process tree it started, not just the PID you were handed.

Output before the verdict

Output is fully drained before an outcome resolves, so you never get an exit code with half the logs missing.
