Scoring rubric: Relationship / Domain / Technical / Delivery / Commercial, each 0-5 (max 25).
<15 needs CEO approval, 15-19 qualifies, 20-25 is a strong fit. Use the score action on a
tender's detail view (not yet built in this scaffold — see README Phase 2 notes) to add a
breakdown; for now scores can be inserted directly via tender_scores.
