Going from 8 bits to 12 bits: 1 / 16 = 0.0625 which is much bigger than 0.001. So maybe 0.05?

>>  What is the minimum bit depth for non-integer serialization? I assume this should be 12, because rec2020 can use either 10 or 12 bits; the percent form of rgb() can use arbitrary precision.

> Not sure I understand the question - are you asking what the smallest bit depth is that could possibly trigger a non-integer serialization? If so, it's 9 bits, right?

No, I'm asking what is the minimum bit depth that we need to preserve. Since Rec 2020 allows 10 and recommends 12, we need to preserve at least 12 bits.
