The header scan (Captain Bob, 2026-11-10): 788 source files -- 351 with the
SL-1.0 header, 12 with the old name (docs/working/experiments, kept by
ruling), 31 under someone else's licence (tools/kconfig, Linux's, GPL-2.0:
kept), and 394 with none. Ruled: the SPDX form; capsules (.4th, .f18) and
proofs (.thy) left for a ruling of their own (mkcapsule's 64x16 block format,
content-addressed capsules).
253 files now begin

as a /* */ block (C, headers, assembly, linker scripts) or # lines (scripts,
Makefiles, Kconfig; below a shebang or a coding line); tools/mkcapsule.c,
which had the copyright line, gets the SPDX line only.
Not touched: docs/working/ (archive and old campaign material, as the
ruling kept the experiments); v4/system/post_cases.c (generated by
v4/tools/mkpost.py, "do not edit" -- the generator has the header).
Comments only: the kernel builds on amd64, aarch64, riscv64; make -C v4
test-32: 39 programs, 0 failures; every changed script parses.

?TERMINAL reads CONSOLE-STATUS; KEY polls it until a character is
pending and then takes it from CONSOLE-RX. Executed on the golden
model at both cell widths, including a transcript of the v3 binary, and
KEY shown still waiting after 5000 instruction words with no input.
v3's KEY returned -1 at the end of its input; here KEY waits.

One case per byte position, like C!: the cell is shifted down with a
2/ loop and masked. It replaces the version built on LSHIFT, RSHIFT
and SWAP calls. C@ now leaves its caller 7 return entries (was 4), and
the words above it gain with it: TYPE 6 (was 3), DUMP 4, Q.PRINT, U.
and U.R 3 (were 2). The signed number words stay at 2: their sign
waits on the return stack.

: EMIT ( c -- ) CONSOLE-TX b! !b ;
: CR ( -- ) 10 jump EMIT
: SPACE ( -- ) 32 jump EMIT
: TYPE ( baddr u -- )
-if OK drop drop NODE-ERROR b! -1 !b ;
OK: if DONE over C@ EMIT push 1 + pop -1 + jump OK
DONE: drop drop ;
They follow v3 (v3/src/word_source/io_words.c): EMIT prints the low byte
of the cell, CR character 10, SPACE a blank; TYPE prints u bytes,
nothing for u = 0, and for u < 0 nothing, with NODE-ERROR set where v3
raised its error flag. TYPE does not check the address range, which v3
does; out-of-range addressing is still an open question in node.h.
New test v4/tests/test_terminal.c, on a node of its own with the console
attached, 939 checks per width. Two transcripts of the real v3 binary
are recorded as expected output:
65 EMIT 66 EMIT SPACE 67 EMIT CR 68 EMIT 321 EMIT -> "AB C\nDA"
S" Hello, v3" TYPE 91 EMIT <text> 0 TYPE 93 EMIT -> "Hello, v3[]"
Also: EMIT of every byte and of wider values, CR, SPACE, TYPE from every
start within a cell at lengths 0..40, bytes with the top bit set and
zero bytes, negative counts, and that TYPE writes no memory. At 32- and
64-bit cells, optimised and ASan+UBSan (`make test`, `make sanitize`).
Five mutations each fail.
Headroom (data cells under args / return entries): EMIT 8/8, TYPE 4/3.
TYPE's depth is C@'s, which is still as written (C@ -> RSHIFT -> SWAP).
Test results on the amd64 host only. This is a development check, not
acceptance (JUSTIFICATION.md section 16).
