MACHINE.md 2.2. Each is its entry's address, push and ;. Every node the tests make carries the host ROM (host_load, Hera's births, the depth and mesh tests' own nodes), and a division by zero inside the ROM returns to the prompt (hosted-check). test_host_quit's fetch outside memory moves past the ROM's range: 16384 is the ROM's first word now the tests' system has its ROM, as the product's always had. dict_hash 0xfec8c47cfc6f437f.
