## Settlement

Why this grade: One service decides when to load a breach, so a month measures its work as much as the world's leaks. Shown, not settled on.
What it costs to move: Not practical from outside. The service verifies a breach before loading it.
When the source is late: A month stays open until it ends and the list is read. A month with nothing loaded is 0. A month the list can never be read for is void.
Precision: Whole accounts, the sum of each breach's account count as the service lists it, by the month it was added.

## As first published, and the proof
