Maverick first or Maverick last?

probably the closest thing to what you’re looking for is to find identifications that are both maverick and disagreements: https://jumear.github.io/stirfry/iNatAPIv1_identifications?category=maverick&disagreement=true.

using the page above, you can also search for specific taxon_id (the taxon of the identification) and / or observation_taxon_id, and you can also look for a particular user_id (identifier) and place_id, among other paramters.

you can open a specific observation returned for each identification on the page, or you can open the set of observations associated with all the identifications on each page in either the iNat Explore or Identify screens.

you can also exclude disagreement=true to get all mavericks, or you can exclude category=maverick to get all disagreements. personally, i like to look for all disagreements because it finds observations that have disagreements even if the disagreement has not triggered the creation of a maverick ID on the observation yet.
