The passage around this formula
What is PROPOSED is the packaging: treating both phases as instances of one operational estimator, []=[]/[] , built from a loop’s phase debt divided by its specific-action invariant, extracted as a derivative across swept loop parameters rather than read off a single phase. That packaging is new; the algebra underneath it is not, and this paper has tried not to blur the line between the two.
