For the first --thanks.I concur. This is not really a canon law question. For what it’s worth, I also concur with your overall conclusion. The hypothetical person is certain that the “marriage” is invalid. How can the person then not conclude that marital relations would be fornication? This seems to be a case where the action (conjugal relations) is not objectively sinful (since the marriage appears to be valid) but is subjectively sinful (because the person is certain that he/she is not married yet is acting as a married person).

For the later I would say it would be “objectively sinful” too for it does not appear to be valid but rather has the appearance of an invalid marriage (see canons above). And objectively an underage person cannot enter into a valid union.
