Getting close!

I was looking for 300.5(J)

Here's what it says for underground runs:

"(J) Ground Movement. Where direct-buried conductors, raceways, or cables are subject to movement by settlement or frost, direct-buried conductors, raceways, or cables shall be arranged so as to prevent damage to the enclosed conductors or to equipment connected to the raceways.

FPN: This section recognizes "S" loops in underground direct burial to raceway transitions, expansion fittings in raceway risers to fixed equipment, and, generally, the provision of flexible connections to equipment subject to
settlement or frost heaves."

[Greg Fretwell]

You will find them missing everywhere. I am not sure I have ever seen an expansion fitting actually installed anywhere. Certainly never on a riser like this. I am reminded of the old picture you had of the RNC sticking about 2' past the end of a building, presumably because of expansion. That said, using strategically placed elbows is a way of healing with expansion.

how could we have known it was subject to movement?

Another example

How would we see it during a home inspection?

It would look like this one in this raceway riser, this picture was posted above.

The expansion fitting was installed.

If upon an inspection where the UG conduit was run as a continuous underground run, showing and no signs of settlement or frost heaves, then there would be no concern necessary.
