What the article says around this equation
where C() is the model’s evaluated capability on a specific threat class, is the threshold defining ASL level k , and is the security and deployment standard the policy requires once that threshold is crossed. This is worth writing out because a threshold-triggered commitment is only meaningful if it is sometimes not satisfied by default — otherwise it is a description of business as usual, not a constraint. Whether the policy binds in practice is therefore an empirical question about later events, addressed below.
