# ── Both sides of a Settings target ─────────────────────────────────────────
#
# An `open` action carries the id of a Settings page, and the two halves of
# that agreement live in different languages in different directories: the
# doctor writes `target="updates"`, and Health decides whether it will accept
# one by looking the value up in `settingsTargets`.
#
# Getting one without the other is not a dead button. `validAction` returning
# false makes `validCheck` return false, which makes `consumeSnapshot` reject
# the WHOLE report -- so a single unlisted target takes every other check down
# with it and System Health goes blank, for a reason nothing on screen names.
# That is what "Open Software Update" would have done had it been given the
# target it was missing without `settingsTargets` being extended to match.
#
# Derived from both files rather than restated, so the next target added on
# either side has to be added on the other.
