Constant BAKE_CLOCK_MASK 

pub const BAKE_CLOCK_MASK: u64 = _; // 2_305_843_004_918_726_656u64

Tensor-bake t clock (only on Tensor10D ground-truth nodes). Matches bake_pipeline’s (metadata >> 32) & 0x1FFF_FFFF, i.e. bits [32..60] — it even grazes quin_type’s bit 60, an existing tensor-only quirk. Documentary only; never asserted disjoint (its role excludes the others).
