Alert rules deployed and verified on CFGMON. Verification surfaced two variants
of the same failure class: a missing time series silences an alert instead of
firing it (fixed with a created-time fallback aggregated via max by, plus an
absent() alert for a vanished CronJob), and a SIGHUP reload that reported success
while serving the old file from a stale inode.
The second one matters most: that trap was already documented in detail, with the
right command and a check, and it still bit — so it was removed structurally
(directory mounts) rather than documented harder.
