Tobias Wunden commented on MH-9225:
-----------------------------------

Looking at the 1.3 codebase I see exactly two ways of getting a workflow into 
PAUSED state:

1) calling the pause method on the rest endpoint, which seems unlikely (I am 
not aware of any service or ui that is using it)
2) returning WorkflowOperationResult.Action.PAUSE as the result of a workflow 
operation handler

This means that there would be a workflow operation in the workflow that is 
calling pause due to its workflow configuration (such as hold for trim) or due 
to a programmatic error. Next to the obvious ones like trimming, I am looking at

* ScheduleWorkflowOperationHandler
* CaptureWorkflowOperationHandler
* IngestWorkflowOperationHandler

all of which are used in case of a scheduled recording to represent the state 
of a recording while the recording is scheduled, ongoing on the capture agent 
or in ingest state. The capture agent will usually report back the capture 
state to the capture admin, leading the capture admin to udpate the workflow 
and move it to the next step.
                
> Workflows automatically go into hold state after inspect but resume 
> processing correctly with a nudge from the resume workflow endpoint
