What format is returned from "ArcGIS for Portal" Feature Service

Question

I'm looking for documentation of the complete format that is sent back, mostly on the transform component

If you look at the HTML view, you can inspect the parameters sent with the request.  The one that's different is the Quantization Parameters parameter sent with the relevant response.

Ex:

Quantization Parameters = {"mode":"view","originPosition":"upperLeft","tolerance":2.388657133974319,"extent":{"type":"extent","xmin":-7241915.960087257,"ymin":5658078.265584529,"xmax":-7038189.895516766,"ymax":5782130.8860775875,"spatialReference":{"wkid":102100,"latestWkid":3857}}}

From an unrelated API doc, it looks like it creates a virtual grid from the geometry, explaining why you see relevant positions for features:

I am using AGOL, below are links to the two different returns:

I've never seen the relevant positions format...  I assumed geometry should have defined coordinates.  Anyway, here's the docs on geometry objects:

ArcGIS Server REST API - Geometry objects

I don't see anything on relevant positions.  In what context is that information returned?  Are you using a hosted feature service or a traditional ArcGIS Server map service with feature access?  What application is that format returned in, one of the built-in templates or a custom app?
