# THIS MUTATES REAL HOMEBREW STATE. It installs and uninstalls the formula
# `hello` on this machine, hits formulae.brew.sh and ghcr.io for real, and runs
# the app with production wiring (no -uiTesting). Nothing may depend on `hello`
# being present or absent — see AGENTS.md#live-end-to-end-canaries.
#
# CI runs this on every pull request as its own job. Run it by hand before
# cutting a release. It is not the deterministic suite; that is scripts/test-ui
# (Brew-UI test plan), which never touches real brew.
#
# Same window/focus caveats as scripts/test-ui — see AGENTS.md#test-troubleshooting
# before running it on a machine you're actively using.
#
# Pass extra xcodebuild args through, e.g. to scope to one test:
#   scripts/test-e2e -only-testing:BrewUITests/ReadOnlyE2ETests
