## Behavioural checks on the kill feed — the top-right takedown stack. They verify a pushed
## line lands on the feed and that the feed caps its length, dropping the oldest. Expiry by
## timer is time-driven and not asserted here; the cap and the push are the whole of the
## list logic the driver depends on.
