stated · refuted
Source
Neville lectures catalog #189
Why
pm-actor-525: refuted by the M7 dating pass (529; 525's readers, packet 021): catalogue date on node 989, which is now certainly dated 1948-02-23.
Reasoning
Lowered to `doubtful` under the #2461 §1(b) extension of the #2435 standing rule. The fenced lecture that carried this date, nid 989 "Thinking Fourth-Dimensionally", has had its claim at 1964-02-03 REFUTED, and no fenced lecture holds the date, so the assertion retains no support. This event cites that same node in field_sources (989), so its support is circular: its only witness is a claim the corpus has withdrawn. ⛔ NOT `refuted`, deliberately: what was disproved is that THIS LECTURE was delivered on this day, NOT that Neville lectured that day at all — he spoke far more often than the surviving transcripts record. Refuting would assert the day did not happen, which nobody showed. Lowering withdraws the false confidence and keeps the day visible as calendar supply. || v1.1/l7/event-preferred/c1: this event claim cannot remain preferred or above doubtful because every actual source lecture carrying this exact date has refuted that delivery and no source lecture independently supports it. The event occurrence is retained, not refuted; only unsupported confidence/preference is withdrawn.
