check_statement requires a non-empty `signatures` list before it reads a statement (the witness verifies the signatures, invariant 128), but no test served a statement without one, so a mutant that dropped the check survived the p256 0.14 PR's mutation run (#480). The keyryx stub gains two modes, no `signatures` and an empty list, and both must be refused as not of the known shape. One scenario, bound. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
