Exclusive day-boundary subtraction, in stated endpoint calendars; inclusive dates add one. No hours inferred.
Year spans are a separate coarse derived field. Same-year and ongoing year spans are blank, not zero.
Observed primary facts, disagreements and per-row source URLs/hash metadata are in both CSVs.
CSV dictionary: secondaryObservedDates lists dates separated by |; exactSources and dateEvidence list records separated by |, with named fields separated by semicolon-space (field: value). Nested values use the same plain-text delimiters. No JSON arrays or objects occur in CSV cells. Numeric UNKNOWN/excluded values remain blank; explicit endpoint UNKNOWN remains text.
