Robinhood put an official CBBTC / USD price feed on the chain and left
its cash pool a puddle. For most of what runs on chain that puddle is
the end of the story: no pool, no market. Not here.

The machine never needed the pool

AUM0 prices every fill against the official feed, not against a pool.
The desk settles two wallets directly at that feed with no pool at all,
and a worker can be the counterparty out of their own inventory. So an
asset becomes managed the day its feed turns on, whatever its pool
looks like. Bitcoin's feed turned on, so bitcoin is managed now,
sitting in the same venue as the stocks, under one law.

One law over stocks and bitcoin

A new venue carries the same twenty six assets in the same order and
cbBTC at the end, priced by the official feed. cbBTC counts in eight
decimals where the stocks count in eighteen, so the ledger, the site
and the keeper now scale every asset by its own decimals. A wallet can
carve "forty percent NVDA, twenty percent bitcoin, the rest cash" and
be kept there, in its own wallet, at zero fees.

On the live chain

Three tests against the real chain: the ledger reads eight decimals to
the cent, the desk crosses bitcoin between two wallets at the official
feed with nothing left in the venue, and a worker fills a buyer out of
their own pocket.

And on mainnet the employee did it unprompted. It found one wallet
holding bitcoin it no longer wanted and another that wanted bitcoin and
had none, and crossed the coin between them at the official feed. No
pool was touched, both wallets ended closer to their laws, and the
venue held neither coin nor cash when it was done.

Unchanged

Your assets never leave your wallet. The contract holds nothing.

Every fill is judged against the official feed, and a worker's pay
is docked dollar for dollar by whatever the fill cost the wallet.

No owner, no admin, no upgrade path. Zero fees.
