OptionalminFloor on the PLP minted for the whole request, as raw bigint shares — PLP is raw
everywhere in this SDK. It is a floor on the MARK, not a share count: a flush quoting
less does not fill smaller, it declines. Omitted → 0n, no floor.
How a miss is handled is the deployment's lp_request_limit_flush_attempts: at the
shipped count of one the first flush below the floor cancels and refunds the request.
