do we need a level for "ALERT"

[mobb]

it would be lower importance than "warn", so it goes
info - burps back some dataset content
alert - things you might want to fix (or examine in the context of this dataset)
warn - things you should fix
error - things you must fix

Gastil wants to color it peach, or cyan

[mobb]

Alert would be to get the attention of a submitter the way INFO does not.
eg. use it on
coverage
header row
duplicate entity check (if one exists)
