19 --detached, -d Run in detached mode (background)
20 --session, -s <name> Session name for isolation
21 --session-id <uuid> Session UUID for tracking (auto-generated if not provided)
22 --session-name <uuid> Alias for --session-id

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)
34 --memory <size|N%|MIN%-MAX%> Docker RAM cap; percentages use daemon capacity
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
38 --cpu-penalty Enable delayed Docker CPU penalty (default off)
39 --cpu-penalty-cpus <n> Penalty cap (default 2 CPUs)
40 --cpu-penalty-trigger <p%> Busy threshold (default 95% of usable CPUs)
41 --cpu-penalty-trigger-window <d> Fully covered busy window (default 15m)
42 --cpu-penalty-release <p%> Quiet threshold (default 65% of penalty cap)
43 --cpu-penalty-release-window <d> Minimum quiet/capped window (default 15m)
44 Durations accept ms, s, m, h; --status reports penalty state
45 --endpoint <endpoint> SSH endpoint (required for ssh isolation, e.g., user@host)
46 --isolated-user, -u [name] Create isolated user with same permissions
47 --keep-user Keep isolated user after command completes

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
