+# Asserts the required inventory in both directions so additions and removals
+# cannot silently drift: every required tool must be present, and the retired
+# RamaLama package must be absent. Pure content assertions — no real Homebrew.
+#
+# Oh My Pi is intentionally NOT asserted yet: the packaged formula lands in
+# ublue-os/homebrew-tap#686, after which the brew line and this assertion are
+# added in the same follow-up.
