Community versus Observation Taxon?

[pisum]

here’s what was noted elsewhere:

@loarie

the Observation Taxon will always match the Community Taxon unless:
a) there is just a single identification, then the Observation Taxon will be defined by that identification
b) the observer opts out of the Community Taxon, then the Observation Taxon will be defined by the observers identification
c) there are no disagreements and there is an identifications of descendants of the Community Taxon, then the Observation Taxon will be defined by the finest such identification (because the community likes that a single non-controversial identification being able to ‘move the ball forward’)*

*if that finest identification is of infra-species rank (eg subspecies), the Observation Taxon won’t roll forward to that rank from the Community Taxon if that identification was added later (because the community doesn’t like what would be Research Grade observations at species rank being rolled forward to Needs ID observations at infra-species rank). However, if the Observation Taxon was initially set at infra-species rank from a single identification, a non-disagreeing identification of an ancestor won’t roll the Observation Taxon back to the Community Taxon.
