pub const MAX_POLY_THRESHOLD: u8 = u8::MAX; // 255u8Expand description
Maximum SSA polynomial threshold supported by the SsaReconstructor.
A byte, because the threshold shares the lower half of the negotiated PixParams word with
SsaGeneratorConfig::surplus_shares — see PixParams::to_u32. The bound is therefore
structural rather than merely checked; the constant exists to name it.
