It's is errRedundantSelector, but maybe errUnnamedSelector would be better? Like unnamed selectors are useless, make sure to pair REP and SELECT clauses: "REP .. IN X" + "SELECT ... AS X"

Thought about this too earlier. In this case, we will have the different error: policy: syntax error: line 1:68 mismatched input '<EOF>' expecting 'AS

Hm, this makes me think -- what if we just change the grammar for selectors too? I.e. make this obligatory https://git.frostfs.info/TrueCloudLab/frostfs-sdk-go/src/branch/master/netmap/parser/Query.g4#L21

For validation we could just check used/unused then.

This variable is used once inside an if, maybe move it there sel :=?

I believe require naturally supports format strings: require.NoError(..., "unable to parse %s", testCase)
