CEN art. 71(h): nothing may be published until 3 hours after the close; the DINE's first provisional data came at 21:00 local in 2025 (Infobae, 26 Oct 2025). 2023 runoff: the DINE provisional count was out on polling night (Ámbito, 21 Nov 2023, quoting 55.69% for the winner). The window closes at the end of Monday 22 Nov local. Provisional, not the result.
