25 --mount <spec> Docker --mount spec (repeatable, docker only)
26 --env, -e <KEY=VALUE> Environment variable for docker container (repeatable, docker only)

33 --on-kill-resume-delay <min[-max]> Wait a random number of seconds before each such resume (default 0)

35 --memory-swap <spec> Combined memory+swap cap (defaults to memory, no extra swap)
36 --cpus <n|N%|MIN%-MAX%> Docker CPU cap; ranges draw once per creation
37 --on-kill-resume-memory <spec> New memory cap before a qualifying OOM recovery

56 --list List all tracked executions (--output-format: links-notation|json|text)
57 --running With --list, only report executions that are still running
58 --upload-log <id> Upload a sanitized copy of the stored log privately
59 --no-sanitize With --upload-log, explicitly upload without secret redaction
60 --stop <id> Ask a detached isolated execution to stop gracefully
