The supplied reporting shows a publicly available roster listing 18 unique participant names by the deadline. El Financiero published a “lista OFICIAL” article on 2026-07-26 (22:18) that explicitly lists 18 inhabitants (15 numbered participants plus three ‘habitante sorpresa’: Gema Garoa, Luis Chaparro and Mariana Ochoa). Deadline (2026-07-24) independently reported the same 15 named participants and the three additional names, yielding the same set of 18 distinct personal names. Because those public announcements/rosters in the evidence unambiguously list 18 unique names by 2026-07-26 23:59 CT, the answer is YES.
