Medium/low confidence: a late biography, not a Croton court file. Stored as a received political-violence claim, not as a unique body count.
Context
Do store the later story as later story.

Why it matters
Printed Croton violence is a humanitarian-harm tradition of low confidence, not a 5th-century BCE docket.
