Symbol j

The passage around this formula

The choice can be expressed as a constrained optimization rather than a preference: $j^* = \arg\min_j \left( \lambda_L L_j + \lambda_C C_j + \lambda_R R_j + \lambda_S S_j \right)$. where $L_j$ is latency, $C_j$ is direct and review cost, $R_j$ is reproducibility loss, and $S_j$ is security exposure for surface j . The coefficients depend on the task. A one-line local refactor and a six-hour repository migration should not automatically use the same execution arrangement.
