Update geometry after edit in real time — via Arcade?

Question

Using Arcade:

Is there a way to update the geometry of an existing feature after an edit is made?

It would be the equivalent of a DB trigger, but using logic similar to the Python field calculator script below:

#written for ArcMap (https://gis.stackexchange.com/q/423806/62572)
def new_shape(geom):
    spatial_reference = geom.spatialReference
    geom = geom.densify("ANGLE", 10000, 0.174533)
    parts = arcpy.Array()
for i in range(geom.partCount):
        part = geom.getPart(i)
        points = arcpy.Array()
for j in range(part.count):
            point = part.getObject(j)
            point.M = geom.measureOnLine(point)
            points.append(point)
        parts.append(points)
return arcpy.Polyline(parts, spatial_reference)

I suspect that's not possible, but just wanted to check to be sure.

I'm having a hard time finding a solution — something that will be executed in real time after a feature is edited. There doesn't seem to be a way to do that. Even the SDE.ST_GEOMETRY functions (for an Oracle db trigger) are too limited.

Attribute Rules can do stuff like that.
