The capstone accepts one coherent switching-energy ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
The capstone audit has to cite every upstream source
The final accepted value is downstream of ramp, energy, work, balance, buck-average, and power checks.
audit=ramp+energy+work+balance+buck+power
The source chain stays accepted as load current changes
Each row rebuilds the full source chain. The load current changes power, but every accepted bit remains source-bound.
