Both corpora are explicit lists and not globs, so a program added to
test/programs is covered by dune test and by @x86 and by nothing else until
somebody types its name here. files.flan, math3.flan and time.flan are typed.
time.flan is the one with something to say. getenv hands back a slice viewing
the process environment and never a copy, which is the exact shape a
use-after-free or an off-by-one length would be, and neither ASan nor memcheck
had ever seen it. files.flan brings three more path buffers through
flan_path_cstr. math3.flan is the cheap one and is here for completeness.
files.flan makes and removes its own tree, so the sweeps' two runs of it see
the same directory both times.
@sanitize is clean with all three in. @valgrind is not run here -- it is tens
of minutes and opt-in -- so those three entries are checked by the next person
who runs the alias.
