  "_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). The 'cases' array holds the GERMAN (de) canonical form and is asserted by BOTH suites — that is the Java<->TS drift guard (en-dash vs hyphen, 'ca.' vs 'circa', season words, range collapse). The Java title formatter intentionally renders German server-side (import titles are always German); only the TS UI formatter is locale-aware, so 'localeCases' (en/es month-name output) is asserted by the TS spec ONLY and must NOT be fed to the Java test. Do not edit one side's expectation without editing this file and the relevant test(s). Season->month mapping note: the Python import normalizer (tools/import-normalizer) is the UPSTREAM authority for which representative month a season maps to (4/7/10/1); both formatters mirror it but it sits OUTSIDE this Java<->TS guard, so a normalizer change is not caught here. See issue #666 and the Markus/Sara drift-guard decision.",
