  changes: Enriched the seeded METPO non-hemolytic child class with DOI-backed gamma-hemolysis
    evidence after a repository-wide duplicate review covering ignored and hidden

  snippet: Hemolysis testing revealed γ-hemolysis for all strains, confirming non-hemolytic
    and non-pathogenic properties.
  notes: Petjul et al. examined hemolytic patterns on Columbia agar supplemented with
    5% sheep blood and reported gamma hemolysis for all assayed Bacillus isolates,
    supporting non-hemolysis as absence of red-blood-cell lysis on blood agar.

  prompt: Resolve a neutral parent axis for absence of hemolysis before narrowing
    parent_traits below phenotype.
  kind: CURATION_TODO
  status: OPEN
  rationale: METPO:1005025 is the seeded superclass of METPO:1005027, but METPO:1005025
    defines the ability to lyse red blood cells; this absence phenotype is temporarily
    parented directly to METPO:1000059 phenotype until METPO has a neutral hemolysis
    axis or another broader parent for hemolysis-test outcomes.
