Predicted at turn 34 with the run in flight, from min_life falling by exactly
1 per turn: the first phase-11 draw on turn 64, exactly 1 word, tail total 1,
bracket = ProcessTurn + 1. The game was played to turn 64 and every clause
held. predict_words, computed before the original ran, said 1 and the
measurement said 1 -- a real check of the model, against 63 preceding turns
where 0 matched 0 and checked nothing.
So the defect lane K warned about is no longer latent: on that turn a
reimplementation modelling ProcessTurn perfectly would have written an autosave
one word out of step.
And the instrument's thinnest part ran live on the same turn -- ProcessTurn
crossed a block boundary (left 11 -> 615, one twist, 20 words) and the bracket
still reconciled to residual 0.
