pub const GENERATOR_FAMILY: &str = "mk-codec 0.4";Expand description
Family-stable generator string (closure Q-10) for vector-corpus
SHA-256 anchoring. Patch-version bumps don’t roll the token; minor-
or major-version bumps do. (Honesty note: the v0.3 and v0.4 minor
bumps missed their token rolls; this token was corrected to
"mk-codec 0.4" in the same regeneration that added the depth-0
vector — that vector decodes only under mk-codec v0.4.0+, so the
corpus must not carry an older family token.)
