What survives forecast error?
Compare idle, clock-based, forecast-committed and hindsight battery schedules under price error, losses and a household reserve. The Go planner selects profitable partial cycles, and a separate replay checks physical constraints and realized settlement.
A measured failure is useful evidence. With 88% efficiency and a 5 kWh reserve, the strongest synthetic error setting gives the forecast strategy 38 losing days out of 120. Its mean is $0.145/day versus $0.097 for the clock baseline. These are synthetic stress outcomes, not validated customer economics or a production controller.

Tool 001 · fleet dispatch
One day's arbitrage is a scenario, not a valuation.
A day-ahead dispatch planner for a fleet of home batteries, written in Go and run on real ERCOT day-ahead prices (hub average, captured 2026-08-13). It charges the midday solar trough, discharges the evening ramp, and refuses to cycle when the spread does not clear round-trip losses.
This is not a revenue floor. One cycle, energy-only, supplied prices, no forecast error or backup reserve. Omitted revenues and optimistic operating assumptions pull in opposite directions; one day cannot establish fleet economics. The local Go study compares forecast schedules with clock and idle baselines under synthetic price error, losses, and reserves.

Kardashev: where humanity actually is
The earlier scale analysis is preserved as an archive. It explores the formula, the assumptions, the climb since 1900, and how many years of growth Type I actually takes at any growth rate you pick.
