before 28 January 1964
bound
Why
Tightens the phase4 L6a envelope from before 1964 to before 1964-01-28.
Reasoning
L6a envelope tightened to the telling day of nid 1832 (certain delivery 1964-01-28); same premise, finer precision. The phase4 L6a bound on this event is `before 1964`, an envelope over delivery YEARS computed without reading text. Its premise is that the fact is true by the time it is told; on that same premise the DAY of the telling is a strictly better upper bound. Nothing is re-decided — the bound is stated to the precision the evidence always supported. The delivery claim for 1964-01-28 on nid 1832 is held at `certain` by the corpus, which is what carries this claim. #2274; the L6a row stands beside this one.
