I have left comments with suggestion where I think changes are required.

There is already an existing route for posting a new comment to an existing forum post:

    app.route('/api/v1/posts/:id/comments')
        .get(forum.commentViewById)
        .post(forum.commentGiveById);

    app.route('/api/v1/posts/:id/comments/:id')
        .patch(forum.commentUpdateById);

This can be found in: routes/forum.server.routes.js

There are dummy functions with TODO comments already existing in the forum.controller for implementing forum post comment features.

In terms of cohesion I think it would be better to keep all the comment functionality in the forum controller and model files. Keep in mind making new comment files would create more coupling than just between forum post and forum comment. A forum has posts and posts have comments. A forum user makes forum posts and comments to forum posts. If we remove forum posts (hypothetically), comments could still remain but without posts to comment to.

I have reassigned myself to this pull request because I am responsible for merging the pull request when it is approved

Aside for the requested changes it looks very good!

The PR includes changes that are not necessarily required for this feature.

For this feature, no new files should be required in the following directories:
routes/
controllers/
models/

For this feature, no changes should be required in the following files:
models/db.server.model.js
config/express.server.config.js

It's better to have high cohesion and low coupling. Making new files for comments increases coupling and reduces cohesion.
