Its job in the formula

Subtract the following term or group from the preceding one. A leading minus marks a negative quantity.

The passage around this formula

Optimizing task success alone invites systems to spend unlimited resources or take unacceptable risks. A more useful objective is J(π)=Eπ[R]−λcEπ[C]−λrEπ[L]−λuEπ[U]J(\pi) = \mathbb{E}_\pi[R] - \lambda_c\mathbb{E}_\pi[C] - \lambda_r\mathbb{E}_\pi[L] - \lambda_u\mathbb{E}_\pi[U]. where R is task reward, C is computational and human-review cost, L is realized loss from harmful actions, and U is residual uncertainty at commitment. The coefficients are governance choices, not model parameters. Hospitals, game studios, semiconductor fabs, and personal coding projects should not assign them equally.
