Neville's seven years of lectures and case histories through July 1953
Date (happened)
July 1953
stated · probable · preferred
Source
derived from the event's own title: "Neville's seven years of lectures and case histories through July 1953"
Reasoning
The event held NO date claim of any kind; its own title states 1953-07 (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.

Why
Dates the retrospective span represented by the event, not a single lecture delivery.
Reasoning
The witness explicitly measures a seven-year retrospective interval ending at the lecture. Nid 1002 has a certain preferred delivery date of 1953-07-19, so subtracting seven years yields an estimated 1946-07-19 start; the conversational phrase 'last seven years' does not warrant certain confidence.
