Reasoning
Qualifying passage ids [547172] belong to telling lecture nids [1860]. Each listed lecture contributes the selected safe envelope year 1965 (MAX of its non-refuted delivery years); 1965 is the MIN across telling lectures.

bound · possible
Why
Corrects the phase4 L6a envelope on this event from before 1965 to before 1968.
Reasoning
Envelope recompute, arithmetic only. The phase4 L6a row on this event states its own rule: each telling lecture contributes MAX of its non-refuted delivery years, and the envelope is the MIN across telling lectures. Recomputed live over lecture nid(s) 1860 that row cites, MAX(non-refuted field_delivery_year) gives 1968, not the 1965 the row carries — the bound was below its own stated rule and therefore UNSAFE: it asserted the event did not happen in 3 year(s) where it may sit. Same premise, same evidence, no re-reading and no re-judgement; only the maximum was taken correctly. The L6a row stands beside this one (append-only). Ruling: #2235 delta 1, architect 378.
