The bug reporting system could take an osm node id, then lookup the live naptan data for differences etc and these could be included in the report, which would go to the authority that has been found in the live naptan data. The other advantage of this, is that if the naptan bus stop changes hands (for whatever reason) then it'll be going to the right group, rather than an out of date group from some old OSM data.To be cleat, to date we have only been given permission to take occasional updates from NaPTAN with agreement from Traveline - and we do not have agreement to 'sniff' the live data on a regular basis as I think you are suggesting. However... I would not be surprised if Traveline agreed to allow access to the live data in time given the motivation that is building within the community to get the data right in both systems.
Until that time, the diffs could be a background thing that is hidden from the reporter of the errors. Though the idea is to make it easier to report errors in the data.
Even with the above restriction, we will of course be able to parse the released version of NaPTAN against the OSM versions of the same data and produce reports for OSM contributors, which could include details of stops that appear to be out of the appropriate authority, or where the NaTPAN and the OSM data have diverged and where one or other of the datasets may be wrong.
That would be an interim workaround, then when the person the gov side reviews it, their system would show the live data compared to the osm data and the dump that osm is using.
