It first tries ‘query-path-info’, which succeeds if the store item is available and contains info about its size, references, and so on. When ‘query-path-info’ fails, it falls back to ‘query-substitutable-path-info’, which allows it to obtain the same information for substitutes. Thus, it doesn’t need to have the store item available locally. HTH! Ludo’.
