Content warning (unresolved, not guessed at): the fields above (lookupTime/lookupTimeDisplay)
are byte-for-byte identical to Time Due Lookup's
response — this looks like the wrong action's content was pasted onto this page. By analogy to the
confirmed STATUS action's output shape (lookupActivityStatus/variable_selected), the real
fields for CATEGORIES are plausibly lookupActivityCategory/variable_selected, but this was not
confirmed with certainty against a live call, so the fields have deliberately not been renamed
here — only the invalid-JSON truncation was fixed. Needs a human/live-test decision before treating
the field names above as authoritative.
