The plan's FormatReport_IsInvariantAndComplete test ends with a
DoesNotContain(",0") guard (after stripping the gc=3/1/0 token) proving
the formatter emits period decimals regardless of the host culture.
It was dropped in the Task 3 commit; restored verbatim. Passes as-is —
FormatReport already uses CultureInfo.InvariantCulture throughout.
