Closing lecture of Neville's extended May 1964 run
Date (happened)
26 May 1964
estimated · preferred
Reasoning
Neville states that his contractual extension continues 'to the 26th day of May and then I close.' The same passage's travel schedule belongs to the securely dated 1964 lecture, so the closing date is 1964-05-26.

Source
derived from the event's own title: "Closing lecture of Neville's extended May 1964 run"
Reasoning
The event held NO date claim of any kind; its own title states 1964-05 (month precision, parsed as "month year"). ⚠ A title in this corpus is a DERIVED artefact — an earlier pass wrote it from the passage text — so this claim is title-derived and is marked as such rather than cited as a source document; the underlying text remains the real evidence and would supersede it. Confidence `probable`, never `certain`, for that reason. Precision is never inflated beyond the title's own wording. CALIBRATION (run v1.1/l1.4/titledate, against the 489 events that already hold an independent preferred date): day 96.1%, month 94.1% agreement. Titles naming a REFERENCE event rather than the event itself ("before", "after", "during the week of", "per ... lecture") are refused outright and never reach this write — reading an anchor as the date is the same laundering phase3b committed when it wrote telling dates onto events.

Reasoning
Neville announces the future closing in node 1776, whose recovered 2/18/1964 dateline exactly matches an independent catalogue claim. || v1.1 type repair: written as `stated` by run v1.1/l4/actor456/7500-7999-b1, retyped `estimated` — the claim cites node 1776, not a passage, so it is this lane's inference rather than something Neville said in so many words (#2117).
