Both tests run against the live session and capture "what it was before"
so they can put it back. Neither checked that what they found was sane,
so one interrupted run poisoned every run after it -- and because each
subsequent run faithfully restored the bad value, the desktop stayed
broken while the failure looked like an ordinary flake.
displays-contract left the monitor at scale 1.25 after a failed revert.
The next run recorded 1.25 as the original and restored the desktop to
it. It now reads the shipped scale out of monitors.lua and refuses to
run when the live display disagrees. A failure to parse that value is
fatal rather than skipped, because silently skipping the check is how
the laundering happened in the first place.
focus-session-expiry kills and restarts the shell mid-session, so an
interrupted run leaves caffeine on with nothing left to turn it off. The
next `focus start` recorded "previously on", handed it back on expiry,
and failed the assertion that caffeine ends off -- identically, forever,
with the desktop unable to idle or lock the entire time. It now refuses
to start unless caffeine is already off, which is the only state in
which the test can tell "restored correctly" from "never released".
Both guards name the exact command to recover with. Verified each fires
on a dirty state and passes on a clean one; caffeine was found latched
on this machine and has been released.
