What the article says around this equation
The deeper question the loop-closure argument sets aside is what happens once loop closure has already been confirmed — once a single, well-behaved genuinely fits every edge. Does a nonzero slope in that fitted potential mean anything has curved? The equivalence principle’s oldest thought experiment already answers no, and the answer can be made exact rather than qualitative.
