State
The run's memory. Written after every step.
- owned by the run, not the process
- on disk, not in memory
- survives a crash or a restart
Suspend & resume
A step that waits. Needs a person only when necessary.
- the run stops, nothing is lost. Nobody watches it
- it reaches people where they already are
- their reply resumes the same run, a minute or three days later
Trace
What every step saw and decided. The audit record.
