Neville leaves after his February 1948 lecture engagement

22 February 1948
estimated · possible · preferred
Reasoning
Passage 527338 says on the 1948-02-16 lecture date that Neville is leaving on Sunday night. Calendar arithmetic gives the coming Sunday as 1948-02-22; this was independently cross-checked with .NET and MariaDB, both identifying February 16 as Monday and February 22 as Sunday. Confidence is possible because the passage witnesses Neville's announced plan, not completion of the departure asserted by the event title, and the carrier date itself is a lone legacy-unreviewed claim.
after February 1948
bound · probable
Source
bound derived from the relation in the event's own title ("after"): "Neville leaves after his February 1948 lecture engagement"
Reasoning
The event held NO date claim of any kind. Its title does not state when the event happened, but it states a RELATION to a known point — "after 1948-02" — and that is exactly what `bound` records. Run v1.1/l1.4/titledate refused this title for a DATE, correctly, because reading an anchor as the event's own date is the laundering phase3b committed; refusing to read it as a BOUND would have thrown away real information. ⚠ Title-derived: a title here is a summary an earlier pass wrote from the passage text, so reading the text supersedes this. `bound` is never `preferred`, so the event still displays no date — which is correct, because a bound is not a date.
