Official Stock Token registry and AATOS allowlist

On Robinhood Chain, address is identity. A token named NVDA at an unofficial address is not a Robinhood Stock Token.

What AATOS does

AATOS keeps a canonical allowlist for agents via stocktoken_list / stocktoken_get and refuses off-list symbols for policy-guarded plans. That is how you stop agents from inventing markets.
