- DU-H1: flags are parsed wherever they sit, so `install --unattended` and `--unattended install` are the same run; any unknown flag, word, or subcommand exits 2 to stderr before a package manager is touched. - DU-H2: every download lands in one private mktemp -d (mode 700) workdir per run, is checked non-empty before sudo tar sees it, and an EXIT/INT/TERM trap cleans up. No fixed /tmp paths remain. - BUG-1: ^t is now toggle-shown — it ticks only the rows the active filter is showing, and @needs expansion stops at the first invasive row, so an invasive package can never be ticked off-screen. - BUG-2: ^t journals what it added, so a second ^t over the same shown set unticks exactly that set; the bind no longer clears the query. - lab: the type verb polls fzf's reported query to a deadline instead of a fixed sleep; marks_settled retries within its deadline. Suite 256/0 host, 214/0 docker (ubuntu:24.04), mutations 24/24 killed (six new mutants re-introduce each bug and all die), lab 6/6 green.
