Global formula analytics from formulae.brew.sh are merged with repo-tracked tap scope Brewfile packages. These are ecosystem-wide install counts - not attributable to a single image lane. A115-package tap (bluefin/brewfile) and a 20-package tap (bazzite/brewfile) are currently tracked. Missing entries stay visible rather than disappearing.
