  • Counts are generated from the same local input the product uses.
  • Configuration defaults are distinguished from live, user-visible state.
  • A limitation is recorded beside each conclusion, not hidden in a general disclaimer.
  • Corrections are dated and sent to [email protected] with a reproducible example.
