A wealth figure that ignores the house is not a wealth figure. Assets
without a market feed - a house, a car, a private loan - are now added
by hand on the Wealth page with a stated value, a currency and the day
the estimate was made; a negative value records a liability. They are
registry entities in assets.finance like everything else, join the
per-currency totals immediately, and a currency held only in an asset
earns its own line.
