Read the equation
Score action a in state s using four benefits and five penalties or costs. Repetition depends on the action, while stall and fallback terms are written as state-dependent. The source supplies a structure for action ranking, not a complete policy or fitted scoring model.

Terms & definitions
The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.
How it works
Read J(a|s) as the quantity being defined or updated by this relation.
Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.
Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.
Assumptions & limits
Weights, normalization, constraints, available actions and tie handling must be defined to make rankings reproducible.

Exact original notation
J(a|s) = U(a,s) + S_sem(a,s) + R_goal(a,s) + B_novel(a,s) − Φ_repeat(a) − Φ_stall(s) − Φ_fallback(s) − Risk(a) − Cost(a)
