Modern lives print a move from Samos to Italy as received, not as a passport file
One sage’s received migration is not a refugee census; low confidence on causes (tyranny of Polycrates as later told). Do store the received Samos-to-Croton heading. In the causal graph this event strengthens Forced-Displacement Scale, a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — a worsening welfare path.
Read the full account
One sage’s received migration is not a refugee census; low confidence on causes (tyranny of Polycrates as later told).
Context
Do store the received Samos-to-Croton heading.
Pythagoras is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Printed migration-tradition is not a civil-registry relocation.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

Named sage as heading of later school reports. Iamblichus, Euclid’s editors, and later math teachers publish the instrument.
