4 · Autonomy rule (grid-independence first)

\n
Every SpazaBoX must trade through a 48-hour grid outage with zero brown-out on cold chain and POS. Grid/generator input is charge-only — the autonomy bus is inverter-first. Compliance: SANS 10142-1 (SA wiring code), CoC per registered electrician before energising any unit.
