-type query_metadata() ::
          #{candidate_count := non_neg_integer(),

```

Source-query capture diagnostics. candidate_count is the deduplicated candidate identity count before local residuals and limits. pushed_down records a nontrivial native condition in the plan, not proof that its command ran: empty collections can skip it. source_calls records actual capture commands. The flag does not mean the full predicate was translated. attempt starts at one and increases only for an explicitly requested retry.
