The passage around this formula

Lines of code, commits, pull requests, agent turns, and completed tickets can all rise while value falls. Generated code may duplicate functionality, increase maintenance surface, or shift work into review. The economically relevant throughput is $Q_A=\sum_i a_i v_i$ . where $a_i$ indicates accepted outcomes that satisfy a quality contract and $v_i$ weights their value. Weighting is difficult; pretending every ticket is equal is also a weighting choice.
