$/kgal shown is the published 30-year pitch on the VWBA 2.0 D-6 credited basis (multiplier 0.82 for the standard 6-challenge configuration; per the canonical SWIG_Corporate_VWB_Cost_Calculator, CLAUDE.md R55). $/m³ (30-yr): ⅛=$0.90 · ¼=$0.54 · ½=$0.33 · 1=$0.28 · 1.5=$0.26 · 2=$0.25 · 3=$0.22.
Worked VWBA D-6 example (1.5-acre, the norm): 698 MGY raw × 0.82 = 573 MGY VWB credit = 2.17M m³/yr; lifecycle 30-yr $1.00/kgal ($0.26/m³). Method A: MGY × 3,784 = m³/yr. Site-specific FI confirmed in Phase 1.
