The solution to the puzzle is a sequence of five letters.  

Let's say you're submitting an answer on November 5th, and you wanted to submit "XABDU" as your solution, you would write a comment: "11/5/25: XABDU".

Please do not try to brute-force this.  Each user gets one guess per calendar day, I'm not going to check every single time stamp diligently so don't abuse this rule or I will block you from the market and be sad.

I will check the market once per day (don't worry if I forget or skip a day, I'm human) at a random-ish time.  

If the value of the market is below 50%, I will give a single hint, which I will compile in the description over time.   If the value of the market is above 50% (inclusive), I will not give a hint.

I think this puzzle will be hard.  The more time that passes without hints, the less likely you will be to solve it.  I anticipate that you will need at least ten hints to solve it, possibly far more.  You might need to collaborate.  You have until the end of the year!

12/1 no hint today (but it is my birthday 🥳, that's not a hint)

12/EVERYTHING BELOW THIS LINE IS AI SUMMARY GIBBERISH

 but there is a definite answer that exists.
