The host node starts in its ROM (entry 12), and the boot feeds it the
system's source through the console: capsules/v4/sys/map-64.f18, the
fourteen .f18 blobs and end.f18, each found, hash-checked and
signature-checked as any capsule, then EOT. The ROM assembles the system
and starts it at (IDLE); the host reads the image record
(v4_image_from_node) for what only the assembled system knows. A ROM
error is reported with its blob, line and meaning, then PARITY:FAIL.
Deleted: v4/tools/mkimage.c, capsules/v4/nucleus-64.f18, v4/capsule/*.v4,
v4/tools/v4tof18.py. The .f18 files are the source now.
- text.c speaks the rest of the ROM's language (set, here, store, start;
v4_text_value, v4_text_start), so the oracle reads the same source:
test_host_rom_nucleus compares the ROM against text.c on the .f18 files,
word for word, image record included. Host tests load the .f18 files.
- mkmap image writes v4_map_image (the map's description of the system);
hosted and the kernel link the ROM and the map instead of v4_image_64.c.
- Hera (Captain Bob's ruling, option 1): births stream the system the ROM
assembled, as assembled code; hera.4th is unchanged.
test_host_unit's host builds the system with the ROM.

WORD, the dictionary words and the code generator run underneath
whatever the user has on the stacks, which are ten and nine deep (D-2).
Measured, they used five to seven data cells of their own, leaving a
line about three. Each now keeps what it works on in its file's
scratch cells and has at most three cells on the data stack; , calls
nothing; and the longest chains of calls are shorter.
The public words of core.v4, input.v4 and dict.v4 get dictionary
headers. NUMBER is split so the interpreter can have a flag instead of
NODE-ERROR. The host-node tests share one memory map, host_map.h.

'header NAME [flags]' in front of a word gives it a dictionary entry in
the layout capsule/dict.v4 uses, linked to the header before it, so the
words of a capsule are in the dictionary as soon as it is assembled.
The name is taken as it stands (it may be ( or + or ;) and the
assembler's own name for the code may differ.
Tested in the assembler's own test, and by FIND and the field words
running over assembler-made entries beside ones (HEADER) made.

The second layer of the compiler capsule, v4/capsule/dict.v4: HERE ALIGN
ALLOT , C, 2, PAD LATEST; an entry layout reached entirely from the xt,
with >LINK LFA LINK> >NAME NFA NAME> CFA PFA >BODY TRAVERSE SMUDGE
HIDDEN on it; and FIND and ' .
FIND is FORTH-79's and v3's. ' is FORTH-79's: the parameter field
address, which for a code word is what FIND gives. ALLOT counts cells
(D-1). 31 characters of a name are significant.
Executed at both cell widths against a list of 300 entries kept in C.
WORD no longer holds its length on the return stack.
