Completion criteria

(What does the end state look like - as long as this task(s) is done, this work is complete)

• Tasks no longer keep reloading updated documents once reloaded once, but can still be updated and reloaded that same day.
• Notifications are sent to slack on reload (right now they are only once per 24 hours)
