A runtime compiled to a binary runs itself (hq ADR 0193)

Browse Source 
A compiled bundle records the binary it is (BinaryOf, shared by the builder and the composer), and
the node's runtime, when it is one, is run as ./<binary> from its own unpacked bundle rather than by
an interpreter and an entrypoint.
