# tool si.act.keep_buyer

the whole profile as it should stand next, with its predicate's tree given in full, its bindings and its ladder: the profile as its next version, ready, or not ready with the compiler's reason; the predicate kept by its hash.

[figure: Over MCP, si.act.keep_buyer takes KeepBuyerInput and returns a card whose body is KindOfBuyer.]

the profile as its next version, ready, or not ready with the compiler's reason; the predicate kept by its hash. The call needs the act grant at the brand rung.
