note to self, lemmas:
1) seeding the prng is fine, but we can't seed the prng because that's not how google did it
2) watermarking is always noise injection
3) noise injection always causes a problem in some cases, nonlinearly dependent on how much noise
4) you can never know what those cases are

Improving Elm PRNG
A bug is uncovered in the de facto PRNG library and alternative PRNG algorithms are suggested.

i sometimes complain about the left being useless because i would like them not to be, but your whole epistemology has to be so fucked up to be a Stalinist that your vote is pretty much a PRNG.

PRNG is not random, but if you gather entropy in the system to produce and unpredictable value, then feed that to a PRNG to "smooth" it out and make it uniform random, it's still random
If it wasn't random the Internet wouldn't work
In linux, what is /dev/urandom?

Hence, changing the PRNG from just any old PRNG to generating based on a specific "key" should be immaterial to the "quality", such as it is, of Claude output.

1) your watermark must not be sensitive to 100% of preceding context exactly, which means you cannot simply seed the PRNG sampler, because then even one character of change breaks the watermark
2) you must therefore alter the sampled text in some way that changes what outputs are probable

One of the annoyances of JavaScript in game dev is that it doesn't supply a proper PRNG, you have Math.random() (which is unseedable and the implementation of which is "idk do whatever") and you have the similarly unseedable Crypto.getRandomValues().
