  "_comment": "Single source of truth for the honest date-label rule set shared by the TS formatDocumentDate (frontend/src/lib/shared/utils/documentDate.ts) and the Java formatTitleDate (backend importing/DocumentTitleFormatter.java). Both test suites assert against THIS table so the two implementations cannot drift (en-dash vs hyphen, 'ca.' vs 'circa', season words, range collapse). Expected labels are the GERMAN (de) canonical form: import titles are always German, and the TS formatter defaults to the de locale. Do not edit one side's expectation without editing this file and both tests. See issue #666 and the Markus/Sara drift-guard decision.",
