The final lesson states the boundary: deterministic weighted-score arithmetic only.

Deterministic Scorecard
The scorecard uses fixed weights and fixed scores.
deterministic scorecard arithmetic
Not Weight Proof
The arithmetic does not prove the weights are right.
weight validity is outside scope
Not Recommendation
The largest score is not a procurement recommendation by itself.
supplier due diligence remains outside scope
Honesty Note
This is deterministic weighted-score arithmetic only. It does not prove the weights are right, make a procurement recommendation, model uncertainty, or replace supplier due diligence.
