Symbol j

P(Δ)={(rj,aj,mj,hj,sj,ej)}j=1n,P(\Delta)=\{(r_j,a_j,m_j,h_j,s_j,e_j)\}_{j=1}^{n},
jj

What this part means

j is an input to the expression that computes the quantity on the left.

Its job in the formula

j is an input to the expression that computes the quantity on the left.

The passage around this formula

A more useful provenance record attaches roles to transformations: P(Δ)={(rj,aj,mj,hj,sj,ej)}j=1nP(\Delta)=\{(r_j,a_j,m_j,h_j,s_j,e_j)\}_{j=1}^{n}. where each event records role r , actor a , model m , harness h , input state s , and evidence e . “Machine-originated” can then mean that an agent produced the first substantive implementation; “machine-verified” can mean automated evaluators generated the acceptance evidence; neither removes the human or institution that authorized deployment.
