Add a hidden language to a polyglot

Question

Inspired/mostly copied but I don't think it's a dupe. Also Inspired.

In this challenge, you will create polyglots that include all languages from previous answers, and another language which you won't share and others must guess.

The first language prints 1, the second prints 2, etcetera.

For example, if the first answer was this:

print(1)

You could crack it as Python 3 (or numerous other languages), then you could write another answer that prints 2 in, say, Befunge-93:

2<3 and print(1)#@.2

Try it online!

Then, the next person to answer would first have to figure out that this was written in Befunge-93 before posting an answer that printed 1 in Python 3, 2 in Befunge-93 and 3 in a language of their choice. Feel free to share a crack if you don't want to post an answer.

To keep this challenge fluid, you must reveal your language if it has been uncracked for a week, at which point anyone can post another answer.

Please, be nice and try to post answers in languages which can be easily polyglotted.

Rules

• The criteria for a valid programming language are the same as those of The Programming Language Quiz, Mark II - Cops:

  • It has an English Wikipedia article, an esolangs article or a Rosetta Code article at the time this challenge was posted, or is on Try It Online! (or ATO). Having an interpreter linked in any of these pages makes that interpreter completely legal.
  • It must satisfy our rules on what constitutes a programming language.
  • It must have a free interpreter (as in beer). Free here means that anyone can use the program without having to pay to do so.

• Each answer must run in less than a minute on a reasonable PC.

• Different versions of a language / languages with different flags / whatever are valid as long as you can get them to behave differently. However, flags must be revealed to avoid obscure combinations.

• Cracking a submission consists of finding any programming language that prints the correct result, not just the intended one. If a submission is run in any language that was not declared or found to work, there are no requirements to do anything, and future answers must be valid in that language.

I/O clarifications

The program must output a decimal integer, optionally as a float with a .0 afterwards. Any reasonable amount of leading/trailing whitespace is acceptable, as is stuff unavoidably printed by the interpreter, or formatting for the integer. Anything else is not.

Ending with an error is allowed as long as that error is printed to stderr, and not standard output - it can't be printed with the number.

Scoring

The person with the most answers wins.

Try it online in Ruby, Jelly, Vyxal, rSNBATWPL, Headass, Python 3, brainfuck, Runic Enchantments, Deadfish~. FISHQ9+. I created this interpreter to make testing easier for others, but it also works with the Kotlin implementation that pxeger's answer works with.

Pxeger's post was (not intentionally) in FISHQ9+, using the kotlin interpreter .jar file supplied on the esolangs page, run with java -jar. When running the REPL and entering the code:

######@######## downloads % java -jar FISHQ9P.jar
>> 4+0#  @ iiiiiiiiio
print(8-(2*5-3)+(1/2)*10+8-4*(2147483647*2%3))#+++++P #++++++++++++++++++++++++++++++++++++++++++++++++++.
0+0#  ^
5_310

It prints 10 (without a leading newline) after the code. To avoid making testing hell for everyone in future, I will shortly be adding a FISHQ9+ interpreter to DSO.

This works because the iiiiiiiiio from answer #9 prints 9, but FISHQ9+ merges HQ9+'s + command in which increments it one more time to 10 before printing. Nothing else is printed.

My intended crack was Crystal before version 0.31.0, which is when Crystal got integer overflow checking by default.

This also works with the version of Crystal on TIO, with -D disable_overflow: Try it online!, but I didn't want to reveal that flag (which the rules would have required), so I chose to use an old version of Crystal instead.

(this flag appears to have been removed entirely in the latest versions of Crystal: Attempt This Online!)
