What "not yet" means on your report

If a check isn't yet available in your municipality, your report will show "Not published by this municipality." for that line, with the same source list we would use if we could. We don't guess; we only report what records show.

Coverage goes up as we load more city layers. The counts on this page reflect only what's in the project's main branch today; city-specific loaders being developed on separate branches will raise the numbers above when they land. We'll update this page in the same change.
