How this was calculated

Recommendation record: bedroom-blackout-and-insulation · Weights: Blackout Potential, Closed Privacy, Child-Safe Configuration Availability, Insulation Potential · Tie: deterministic source order · Confidence: governed editorial synthesis.

Numeric ratings are retained here as calculation detail only: effectiveScore = rating for positive weights, otherwise 6 − rating; weightedAverage = Σ(abs(weight) × effectiveScore) ÷ Σ(abs(weight)); score100 = ((weightedAverage − 1) ÷ 4) × 100.
