about

nx_batt_econ.nx -- shared economic CORE for the battery-reclamation finance organs (DRY #15). Pure i64 cents, no-float, NO imports. Both nx_batt_finmodel (the workup) and nx_batt_bizplan (the written plan) compute from THIS single source, so the plan can NEVER drift from the model. Constants are itemized + line-summed in nx_batt_finmodel (its gate asserts the sum == these); figures grounded in knowledge/research/2026-06-23-battery-reclaim-cost-basis.md (verified anchors + flagged assumptions). license_tier: ORIGINAL
