Where this source appears
5 records across 5 decades and countries. Documented gaps are included; a source cited for a gap does not establish a value.
0 of 5 records have a current source audit. A transcription check reads a declared numeric field from a pinned local source file; a calculation replay reads its operands and applies the declared method and rounding rule. A source audit does not independently validate the source or every claim in a record. The date is the last successful local audit; the build checks that its bindings still match.
