If I have run cabling at my own home, and am having a specific issue after having made some troubleshooting attempts and observations, is it on topic to present the observations and issue here to ask about the problem?

Home cabling issues are not on-topic on Network Engineering; they are on-topic on Super User; as I mentioned in my comment, our members answer at Super User on occasion, and there isn't much benefit for asking on Network Engineering when it comes to cabling issues. In fact, if you look though my SU answers, I often cherry-pick interesting questions that were closed on Network Engineering, and then re-posted / migrated to SU; This question had similar symptoms, although you might not have the same problem.

Now to be explicit, why aren't home cabling issues a good fit here?

• Network Engineering assumes you're a professional with either:
  • Access to professional cable test equipment, such as a Fluke CableIQ. This gear is prohibitively expensive for home users, but no serious commercial networking operation should be without something like it. These meters do everything for you... link test, cross-talk tests, identify which pairs are good / bad, etc... as long as you know how to use them, I can't think of a reason for a professional cable installer to ask questions on Network Engineering because the task is so completely managed by these units (that is a good thing)
  • If you don't have access to a professional cable tester, you have the budget to hire someone who does. Network cabling appears deceptively simple; however, there are things you can innocently do to mess it up. For instance, most Cat5e is only rated to 25 lbs of tension; if you pull harder than that in the process of installing in tight circumstances, you can ruin the cable. Cabling technicians have meters that can detect these kind of problems.

Both conditions above are quite unusual for home networking use-cases. In fact, if you had either, it's unlikely you'd be insisting on free support from us to help make your cable.

Final note: the OP claimed that his continuity meter qualified as professional network test equipment; however continuity testers are not sufficient; there is a lot more that goes into making ethernet cables than merely ensuring the pins have electrical connectivity to each other.
