Power out? It is still a toilet.
Aurora separates essential sanitary functions from high-energy comfort functions. The backup architecture keeps the fixture usable without pretending a compact battery can run heated water and warm-air drying indefinitely.

Primary emergency requirement: flush remains available without household electricity.
A low-energy or no-electric pressure path can preserve basic bidet capability.
Up to one week of essential standby is a design target, not one week of heated full-feature operation.
Access models preserve a small number of emergency height movements.
The battery is a service part, not a permanently buried disposable component.
Seat heat, water heat and warm-air drying disable first during an outage.
Failure philosophy
Internet down: still works. Electronics fault: still flushes. Battery empty: manual sanitary functions remain available. A smart toilet should degrade gracefully toward an ordinary toilet—not become unusable.
