pub const CANONICAL_FORM_VERSION: u32 = 3;Expand description
Canonical-form version (see module docs). Bumped to 3 to make node
ordering total when NodeProto.name is empty by extending the
topological tie-break with output tensor names and a canonical node
digest fallback. This is a compatibility break: models with previously
ambiguous (name, op_type, domain) ties can now receive different
κ-labels than canonical-form v2.
