Ternary secret key

[j2kun]

I was looking at

CROSS/jaxite_word/key_gen.py

Lines 19 to 25 in bca0954

	def gen_ternary_uniform_polynomial(
	degree: int, moduli: list[int]
	) -> RnsPolynomial:
	"""Generate a uniformly random RNS polynomial in R_Q = Z[X] / (Q, X^N+1)."""
	coeffs_q = [secrets.randbelow(2) for _ in range(degree)]
	return gen_rns_polynomial(degree, coeffs_q, moduli)

and I noticed the function name says "ternary uniform", but the values sampled are in [0, 1]. Is this a mistake? Should it instead be sampled from [-1, 0, 1]?
