- capsule/log.v4: the level constants LOG-ERROR .. LOG-DEBUG, LOG-LEVEL!
and LOG-LEVEL@, LOG-ERROR" .. LOG-DEBUG" and LOG-ERROR-STR ..
LOG-DEBUG-STR. A message is printed if its level is at or below
LOG-LEVEL, as v3's line -- colour, level, text -- without the time of
day, which a node has not got.
- LOG-xxx" compiles like ." : the level, a call to (LOG"), the text. SEE
shows it as text. COLD puts LOG-LEVEL back to LOG-INFO.
- tests/test_host_quit.c: ten transcripts of the v3 binary, every level
at every setting.

- capsule/editor.fth: the block editor as FORTH source, which the node
compiles itself. It is a vocabulary, EDITOR, used at the ordinary
prompt: n EDIT, then L N B T P E D S H R I WIPE DONE. v3's EDIT, a
shell of its own, is not carried over (ruled 2026-10-05); v3's L S and
SHOW are kept in FORTH as they were, with COPY.
- system.v4: COLD (the system as the loader left it), WARM, PAGE,
VERSION, 79-STANDARD (FORTH-79: silent), and DEFER IS DEFER@ as v3.
- input.v4: where words are split at blanks a zero byte reads as a blank,
so a block never written, or filled a line at a time, loads cleanly.
- tests/test_host_quit.c: the editor's source fed to the prompt line by
line, every command on empty and full screens, what reaches storage;
the system words; deferred words.

- VOCABULARY DEFINITIONS CONTEXT CURRENT FORTH, and v3's ORDER. A name is
looked up in the CONTEXT vocabulary and then in FORTH; a new entry goes
into the CURRENT vocabulary; : makes the CURRENT vocabulary CONTEXT;
FORTH is immediate.
- WORDS lists the CONTEXT vocabulary. FORGET takes what was defined later
out of every vocabulary, and a vocabulary that goes gives way to FORTH.
- v3's vocabularies separate nothing: a word defined in one is found from
every other, and one redefined in a vocabulary replaces FORTH's for good.
- tests/test_host_quit.c: isolation, chaining to FORTH, two vocabularies
with the same names, FORGET across them; and DUMP is now checked to put
BASE back.

- compile.v4: CASE OF ENDOF ENDCASE, as v3 (they nest; a word out of
place is a control structure mismatch); ['] and [LITERAL].
- quit.v4: S" and its run-time word; at the prompt the text is copied to
PAD.
- capsule/system.v4: WORDS and VLIST; FORGET (FORTH-79), which gives the
space back and will not remove a word below FENCE -- the capsule's own
words -- where v3's FORGET DUP succeeds.
- tests/test_host_quit.c: ten more transcripts of the v3 binary, and
nesting, the fence and the listing.
