pub const UNCLOSED: i64 = _; // 86_400i64Expand description
How long a claim on a part that stays put (invoices) still holds it once lapsed, unless it says it closed: a computer whose sync stopped, or whose claims a phone’s sync app brings half an hour late, may still be numbering (review of 5 October 2026, F7); one gone without closing (a crash, a computer given away) holds it a day, then no more.
