April 1967 magazine publication of Bishop Pike's article
Date (happened)
April 1967
stated · probable · preferred
Source
derived from the event's own title: "April 1967 magazine publication of Bishop Pike's article"
Reasoning
The event held NO date claim of any kind; its own title states 1967-04 (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.
April 1967
estimated · probable
Why
Month/year of the named issue; no release day inferred.
Reasoning
The issue month is directly stated and the certain lecture delivery fixes the year as 1967. No publication day is stated, and magazine cover months may precede physical release, so the claim remains month precision at probable confidence.
Told / reported
24 March 1967
estimated
Why
Telling date inherited from the lecture delivery claim.
Reasoning
Passage 535403 belongs to nid 1269, independently dated 1967-03-24 by catalog and transcript chrome.
