# Dominance Check
Identify dominated alternatives (where another alternative is no worse on all criteria and strictly better on at least one) and non-dominated alternatives (Pareto front) in the scoring matrix.
## Execution
Subagent receives the scoring matrix, performs pairwise dominance relationship checks, and outputs the dominance graph and classification results.
## Why Subagent
Dominance checking requires O(n^2 x m) pairwise comparisons, logic-intensive but self-contained, suitable for independent execution.
## HARD-GATE
Each "dominated" determination must specify the dominating alternative, and verify the strict definition of dominance (no worse on all criteria + strictly better on at least one).
