Student or Learner
Here's the diagram from my diagramming book. It say it's an adjective.
Emma's has none of the characteristics of an adjective except that it modifies a noun. It has all the characteristics of a noun ( which include functioning as a noun modifier).
Relative clauses and preposition phrases can also modify nouns. That doesn't make them adjectives.
Quoting from the book: "An adjective is a word that modifies, or describes, a noun or pronoun. “
“Adjective can tell what kind, which one, how many, or how much."
Accordingly to the meaning above, if we ask the question what kind of class we know it is Emma's class. That's one characteristic in the adjective quoted. In this instance "Emma" is acting as an adjective.
I am failing to understand your arguments put forward. Are you are arguing nouns cannot act as an adjective?
Here’s another resource regarding nouns as adjectives.

Most modern grammarians do not find it helpful to speak of a word in one word class acting/functioning as a word in another class.
In, for example, a high wall, high, like all prototypical adjectives, has comparative and superlative forms (higher, highest), and it can be modified by intensifiers such as very and extremely. The noun brick does not have these characteristics.
In a brick wall, brick, like all prototypical nouns, has plural and possessive forms (bricks, brick's, bricks' ). It can function as the subject, direct object and indirect object of a sentence, and as the object/complement of a preposition. The adjective high does not have these characteristics.
Both nouns and adjectives can act/function as noun modifiers.

Such an unhelpful response, talking about superlative and intensifiers I don't see any relevance to "Emma" being an attributive adjective. I think the response was more to do with demonstrating your prowess with words, which I am grateful for adding to my vocabulary.
No idea what the abbreviated word sct means - so unhelpful.
So to deduce what you have written are we in agreement that "Emma" acting as an adjective then?
For some reason I sense we are now in agreement. Have our planetary stars come to alignment?
There's none so deaf ...
I think we share the same understanding except you don't like to call it adjective but prefer to call it a noun modifying another noun.
