What are the requirements for entering Thailand with a recent positive COVID-19 test and a recovery certificate?

Has anyone entered BKK with an old (within 90 days) positive test and a “Certificate of Recovery” from a doctor?

I am trying to sort out exactly how that works.

I contacted American Airlines today and confirmed with them that I will not even be required to test 72 hours before boarding if I can provide the original positive test and the latter of recovery that are both withing 90 days of boarding.

However, at one point the person at AA that I was talking to mentioned that they pretty well just go off what is on Join Sherpa and then permit or deny boarding based on the requirements of the destination and transiting countries.

I checked on Sherpa and for Thailand it says that a negative test is required 72 hours before departure and makes no mention of any provisions for a recovery letter.

That said I am certain I have seen posts and comments on the page from members who have entered on a recovery letter. I know I seen some screenshots of official government statements on this and I also recall people posting links to government documents that addressed this type of scenario.

Another thing that I wonder is this;

Lets assume that a person was allowed to board and fly with a test that was positive (say 45 days ago) and a recovery letter that was written a few weeks later, what happens when you arrive in BKK for your 7 day AQ?

If you happen to be one of those people who is testing positive for several weeks or more after recovering (why you have a recovery letter), what happens in BKK?

Update

On the Thailand Pass website, under the Consular Affairs section at the bottom, there is a link to a PDF document called "Thailand Pass Facts".

In that document on page 7 it specifically states;

Applicant is also required to have an RT-PCR test result that is issued within 72 hours before

departure and bring the results to present to the Health Control station upon arrival. This

requirement is not required for Thai nationals entering under the AQ scheme and for children aged

below 6. Please note that your test result must be in hard copy and in Thai or English language

only.

** If the applicant’s RT-PCR test result is positive, they must present a COVID-19 recovery form

certifying that the applicant has recovered from COVID-19 within 3 months before their travel.

So that seems to address the question of what happens when arriving in Bangkok. It would seem that they want the test to be done 72 hours before and, if you're allowed to fly still, when you arrive in Thailand you will need the Certificate of Recovery.
