      See e.g. this small repro where the graph incorrectly claims that 'a.unknown' is not an array, even though it's the empty array.

       

      TEST_F(PipelineDependencyGraphTest, MissingPathChecksPrefixArrayness) {
    setPipeline(
        "[{$project: {a: 1}},"
        " {$set: {a: [1, 2, 3]}},"
        " {$set: {'a.b': 1}}]");

    runTest([&] { ASSERT_TRUE(graph->canPathBeArray(nullptr, "a.unknown")); });
}
