Can I add a note to my own incorrect story ID answer, explaining why it is incorrect?

Question

Background

Over a year ago, a story ID request was asked, about a lone man manning some sort of space station. I answered it, and even though my guess wasn't the actual story the querant was looking for, it helped them enough to figure it out themselves.
Which is great!

They accepted not their own self-answer, but my answer, since that helped them the most.
Which is fine, too.

I then added a note to my answer, pointing to the correct answer. I didn't want to see my incorrect although helpful answer up voted too much.

NB

While this answer has been graciously accepted by the OP, it was not the actual story they were looking for. That was Halfway House by Robert Silverberg, as evidenced by their own answer.

This all happened on the same day.

Edits

Recently, the note pointing to the correct answer was removed from my answer. The editor pointed to several discussions on meta, most notably one about adding in such a header as I had done.

Still, I thought it only fair my incorrect but accepted answer should point to the correct one, so I added the note back, this time as a footer.

It was removed again.

Rationale

Now I agree we shouldn't delete incorrect story ID answers, as they can help other users find similar stories and help prevent the same wrong answer being given over and over.
I also agree we shouldn't change an existing answer too much, whether accepted or not.
And I agree we should let the votes do their job on incorrect answers. However, I would like to help users cast informed votes. Therefore, I'd like to add the information about my answer's (in-)correctness to the answer somewhere. I have done this before occasionally on incorrect story ID answers of mine, to help point other users in the right direction.

The main difference with the previous discussion about adding such a header, is that this concerns my own answer. I'm not "stealing reputation" from anyone but myself.

Question

Can I be allowed to add a note to my own incorrect story ID answer, accepted or not, to point out why it is incorrect?

Other solutions

One suggestion was to put it in a comment. I think that's a suboptimal solution, since comments should be ephemeral. There's no guarantee for it to remain.

Of course we could try to get the querant to accept the correct answer. This has been tried. But accepting answers is their privilege, and they feel my incorrect answer helped them the most.

Other Situations

Note that my question is strictly about answers to story-identification questions, where an incorrect answer serves as useful information for other users.

Also note that I'm only asking about doing this with one's own answer.

Answer 1

The user who asked the question should be encouraged to accept the correct answer

If the user who asked the question accepts the correct answer then no notice on your incorrect answer is necessary. A moderator has already encouraged the asker to accept the correct answer in this case. Other users have done so as well.

However, the asker may still choose to accept the incorrect answer for whatever reason. If that is the case then no one can stop him (not even a moderator), and the incorrect answer will be pinned to the top.

Assuming the asker chooses to accept the incorrect answer, we require a workaround:

You should be able to add a note pointing to the correct answer as a last resort

The previous discussion about adding such notes covers the situation in which someone else edits an answer to post a notice that it is wrong. None of the answers in that discussion address this situation, in which you are attempting to improve your own answer.

The top voted answer on the previous discussion says:

Adding a note to their answer saying "THIS IS WRONG, SEE MY ANSWER BELOW" would be a form of vandalism.

I agree with that statement, but it doesn't say that you can't edit your own answer. It clearly does not apply since you are not adding a note for users to look at your competing "answer below" -- it's your own answer you're editing.

The second highest voted answer also only applies to editing such a notice into someone else's post:

Inserting chunks of text into other people’s post because you don’t like their answer is an abuse of editing privileges, as well as being just plain rude.

The third answer says the same thing -- don't add a notice to someone else's answer. The same answer also says:

work with the answering party on correcting his/her errors

That's actually what you're doing, only you are also the answering party in this case.

It's also worth noting that the user who asked the question thinks it's vandalism to remove the notice you posted, as @Valorum did:

@Valorum any particular reason for vandalizing the answer?

This situation (in which some users are arguing that the "rules" prevent you from adding a notice to your answer) reminds me of the discussion on main meta as to whether or not individual sites can override general Stack Exchange policy. @Shog9's answer includes this guidance:

Among [Wikipedia's] myriad rules and policies, can be found this meta-policy:

If a rule prevents you from improving or maintaining Wikipedia, ignore it.

What a wonderfully subversive bit of guidance, eh? Kinda turns all the rest of the rules into sort of an idiot test, right?

Well, no. Rather than granting the reader carte blanche, it serves as a reminder that these rules exist for a purpose - and that it is wise to keep focused on this purpose rather than the rules themselves.

The purpose we need to focus on here is that we want to help both the OP of a story ID question as well as any future visitors identify the correct story in question. Graciously adding a notice to your own answer to highlight the correct answer serves that purpose. Broadly interpreting a rule established for a different situation (editing someone else's answer) does not.

Additionally, as @Rand pointed out the added notice can help ensure that story ID questions are not incorrectly closed as duplicates, since story IDs are considered duplicates based on the accepted answer, which in this case is not actually the right answer.
