What changed

  • New Style article: Evaluate into a DateFormula with a literal like ‘1W’ can fail outside English
  • Paired bad/good scheduling samples show the issue and the invariant-input fix
  • Style review skill gets narrow routing to the article, plus a new positive/clean evaluation pair
  • Direct CalcDate diagnostics remain owned by the analyzer (AA0462)
  • Frontmatter and index checks passed; runtime locale tests were not executed
