The third bullet of the issue's ask, dropped in the first pass and caught
in review: a filter value that does not resolve is a near-miss far more
often than an invention, and an error that only lists all 18 available
names makes the reader do the diff by eye -- on the one occasion they
already know they mistyped something.
Thresholded rather than always suggesting the minimum-distance
candidate: a wrong suggestion is worse than none, because it invites a
second failed attempt at a name that was never there. The bound scales
with the needle (a third of its length, capped at 3), so a short name
does not match half the repo and a long one still tolerates a typo or
two, and an unrelated word falls back to the full list.
Tie-break is on length then alphabetical, so the suggestion does not
depend on the order the forge happened to return its labels in.
