Build the one-tonne biochar mass and energy ledger

Build the one-tonne biochar mass and energy ledger

For a fixed one-tonne dry feedstock scenario, record every carbon and energy flow, including feedstock carbon, char yield, syngas, and process energy, with units and a source for each factor. Deliverable: A ledger file with flow, value, unit, and source, plus a reconciliation column showing inputs and outputs balancing to within 1%.
