Input json file of host list for history data is needed to run. See host_list.json file in this repo.
Comuputed result below shows the same cohort Id as Chromium that has the history of servers included in host_list.json.
This is only tested in the FLoC version of "Chrome 2.1".
Chrome requires the following requirements for the domain list in your browsing histories. Please be sure if your domain list for this simulator meets them when you compare the result of cohort Id between Chrome and floc_simulator. You need to use the exact same domain list as that used in Chrome.
// computation. The history entry is eligible for floc computation if all of the
// following conditions hold:
// 1) the IP of the navigation was publicly routable.
// 2) the interest-cohort permissions policy in the main document allows the
// floc history inclusion.
// 3) either the page has an ad resource, or the document.interestCohort API is
// used in the page.
