A sheet is a dated thing, so it should stay dated. Each morning I pull the rules, the tide and the wind, and the page at
/today.html becomes that morning’s read. These are the ones before it, kept exactly as they were filed.
If a rule or a limit changed after the date on a sheet, the old sheet does not quietly update — that is the point of it. For what is true today, read today’s sheet. For what the paperwork said on the sixth, read the sixth.
Before Monday 26 Oct 2026 the sheet was rewritten in place at the same address each morning, so those mornings were not kept. That is a named gap, not a version of the record I invented after the fact.
