Reasoning
Qualifying passage ids [536551] belong to telling lecture nids [1305]. Each listed lecture contributes the selected safe envelope year 1967 (MAX of its non-refuted delivery years); 1967 is the MIN across telling lectures.
before 13 November 1967
bound
Why
Tightens the phase4 L6a envelope from before 1967 to before 1967-11-13.
Reasoning
L6a envelope tightened to the telling day of nid 1305 (certain delivery 1967-11-13); same premise, finer precision. The phase4 L6a bound on this event is `before 1967`, 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 1967-11-13 on nid 1305 is held at `certain` by the corpus, which is what carries this claim. #2274; the L6a row stands beside this one.
