webauthn_credentials.user_id and webauthn_challenges.user_id referenced users(id) with the default ON DELETE NO ACTION, so a future user-delete would either fail or leave orphaned auth material. Recreate both FKs ON DELETE CASCADE: a bound passkey and a pending challenge are ephemeral and must not outlive the account. Scoped to the passkey tables only, not blanket, so retention-bearing child data (world_backups) is not swept away with an account.
