From the ACX 2025 Prediction Contest:

I will resolve according to the Metaculus resolution:
This question will resolve as Yes if, in calendar year 2025, at least 1,000 deaths have occurred in direct conflict between Iran and Israel, according to reports from credible sources. To the extent possible, only deaths caused by and to citizens of each country, members of the military of each country, or people within the borders of each country will be counted toward the 1,000 death threshold.

Direct conflict is defined as conflict between the military forces or law enforcement of Iran and Israel using kinetic, explosive, chemical, or nuclear means and all deaths caused by such a conflict count, including civilians. Deaths from attacks by or towards proxies (e.g., Iran's proxy Hezbollah) do not count for the resolution of this question.
