(OP) (LIT) (BRANCH) (BRANCH>) (RESOLVE) (LABEL), entries 6-11: the code
generator of any language built on the machine (MACHINE.md 2.1). asm.c's
layout rules with text.c's branch placement; 400 random sequences agree
word for word with asm.c at both widths, memory-full and out-of-reach are
refused on both sides, and a ref with no branch is refused, not looped on.

(FIND) ( -- rec | 0 ), (DEFINE) ( value kind -- ) and (OPCODE) ( -- op | -1 ),
entries 3-5. Names are refused as text.c's define refuses them, compared
case by case with text.c; a set variable may be set again. 256 hash heads,
records growing up and names growing down in dictionary space, used only
while the ROM assembles. text.c gains the data directives #, and ", (the
ROM's language; its mnemonic and reserved-word tables are data); the
nucleus image is byte-identical.

The ROM's source is F18 code in capsules/v4/rom, assembled off the node by
v4/tools/mkrom.c with the memory map's constants from v4/tools/mkmap.c
(MACHINE.md 2). main.f18 is the entry table payloads call through (2.1);
in.f18 reads the console and splits it into tokens exactly as text.c does,
the token held packed as a counted string. The ROM's state is a reserved
area of the map (host_map.h ROM_*). text.c gains the constant directive,
so the off-node assembler and the ROM speak one language. The map also
names (NUMBER)'s state, for the next task.
