Reasoning
Qualifying passage ids [535690] belong to telling lecture nids [1278]. Each listed lecture contributes the selected safe envelope year 1967 (MAX of its non-refuted delivery years); 1967 is the MIN across telling lectures.

bound
Why
Tightens the phase4 L6a envelope from before 1967 to before 1967-04-21.
Reasoning
L6a envelope tightened to the telling day of nid 1278 (certain delivery 1967-04-21); 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 1967-04-21 on nid 1278 is held at `certain` by the corpus, which is what carries this claim. #2274; the L6a row stands beside this one.

Reasoning
He says from his own experience the only word for what is seen is 'the serpent', and 'I, the Son of man, I'm lifted up in the same way' (passage 535690). The chronology dates his serpent-of-light ascension to 1960-04-08 (1259, 'Serpent-of-Light Vision / Ascension'; 18342). A later serpent encounter, c. 1963-05-24 (15330), is a different act.
