-3. Scores compound pairs with **Hungarian match mean**:
-   - Build matrix `S` where `S[i,j]` is the cytescore between author part `i` and algorithm part `j`.
-   - Pick `k = min(m,n)` one-to-one assignments that maximize total score.
-   - `match_mean` = mean of assigned cell scores.
-   - If `m ≠ n`, multiply by coverage `min(m,n) / max(m,n)`.
