Thanks, I installed the attached commentary patch into the development repository, to cite the presidential decree. The current TZDB release matches everything you wrote through fall 2026 for all three Chilean locations, so it should be OK. For timestamps after 2026 TZDB guesses that DST will continue with similar rules, as this seems more likely than no DST (and we must guess *something*).
