I largely concur with the observations posted by kateg.
Further observations:
To be clear: your status, and more to point if you lose PR status, has NO Direct impact on that of your spouse.
That is, her PR status cannot be revoked because your PR status is revoked.
Otherwise, however, your spouse's status is at least technically dependent on satisfying the condition to cohabitate for two years. And of course on compliance with the PR Residency Obligation.
Minister McCallum has recently suggested the Liberal government will remove the two-year condition of cohabitation for sponsored partners. Obviously this cannot be counted on to happen until it actually does happen. But it does signal that under his leadership, IRCC is not likely to aggressively enforce these conditions. Even as is, it appears there is little or no effort to independently enforce this condition; enforcement appears limited to cases in which a complaint or report is made (typically by the sponsor), a fraud tip is made (which would be for those cases in which the marriage and sponsorship itself was fraudulent, typically involving a sponsor paid to sponsor or otherwise receiving something in exchange, like in exchange for a reciprocal sponsorship) or in situations for which a breach of the condition is more or less blatantly obvious, too blatant to ignore. While this should not be interpreted to be a license to ignore the condition, it does suggest that if no one complains, the couple remain in a genuine relationship, and there is not a blatant disregard for the rules, the odds are high that a technical breach of the condition will not trigger enforcement.
kateg suggested a strategy to comply with the condition in the event the appeal is lost and consequently your PR status is terminated, and you have to leave Canada.
Timing Problem:
There is one glitch in the timing in the strategy suggested by kateg: your spouse will not be eligible to sponsor you until late January 2021. PRs themselves sponsored are not eligible to sponsor a partner for five years after landing. (I have not looked at the particular statutory and regulatory provisions to see if there is a potential exception; one of the problems with the new PDI format is that unlike the Operational Manuals, the PDIs tend to not give specific reference to the applicable statute and regulations, making it more work to check these things.)
See a lawyer:
The combination of having been issued the PR TD and how close you cut it to the PR RO threshold, seems to me it is worth making a concerted effort to build the H&C case, and that there is a good chance a lawyer could really help.
