Also, replacing the
0:`1:
with
0:`1:`$
which suggests it's a bug with the special code for atomic agenda.

a workaround btw, is
(lr ; 0:`1:@.(0 ~:"0"1 ])
ie. first take rank 1 then rank 0 of subexpressions.

Subject: Re: [Jgeneral] a bug with agenda or =/~:
I can re-produce this. The smallest argument I've found for which the
problem remains is this:
(lr ; 0:`1:@.(0 ~:"0 ])"0) &> 'f';(i: 0);i: ,3

|'f' |1 |

I can also re-produce this in 32-bit J8, 64-bit J7, and (differently) in
32-bit J7. In this last version, the smallest problem case I found was
this:
(lr ; 0:`1:@.(0 ~:"0 ])"0) every 't';'f';0;i: ,3

this is correct result:

the tests on 2d arrays that start with 0 or include a 0, when some of the
previous items are included return random results instead of 0 1). The
result is correct if some of the previous items in this list are removed.
