aka this pipeline:

- could a problem ever exist here? (by experience or by semi-regular checking or by rotation); this is referring to possibility, and may generate false positives.
- looking at the actual data, does a problem exist here? (self-think the tags)
- how is "this" a problem? (check the specs)
- can we explain this problem? (e.g. new user)
- any known solutions to this? (check the specs again or ask at forums, etc.)
