Captain Bob, 2026-11-13: "Create the issues then fix them before the long
acceptance test runs"; #16: "Nightly".
#190 -- make -C v4 post79 did not reproduce POST:
- mkpost.py runs v3 with address randomisation off (setarch -R): its
printed addresses (>IN, FIND) are the same each run, so POST79.md is.
- v4/Makefile post79 builds hosted v3 from this tree's source first and
uses it, not the lfs/ copy, which can be older.
- post_cases.c and POST79.md regenerated: 539 cases -- LOAD.rest_of_line,
which v3 gets through since it changed after 2026-10-07. Two runs the
same. POST_FLOOR 538 -> 539 (#173).
- test_host_unit.c takes the table's count, not 538 typed in the test.
#16 -- scripts/nightly.sh v4-checks: make -C v4 sanitize hosted-check,
logged under logs/<TS>/v4-checks/, refused without qemu-user; nightly.yml
runs it after publishing, before the proofs, installing qemu-user if the
image lacks it.
Evidence (logs/20261113-014927/post79, -024314): before, regenerated with
nothing changed: 539 cases and addresses differing run to run; after: the
same twice, hosted POST 539/539; test, test-32 99 programs 0 failures;
v4-checks 79 programs under the sanitizers 0 failures, the hosted builds
alike. The first verification failed at test_host_unit.c:442 (kept); a
stray v4-checks run stopped at once is kept, labelled (-014453).

The boot runs POST with the runner (v4/system/post.c) after the capsules:
it feeds the 538 cases to the node and judges them from outside. A
case's printing no longer reaches the console. What the cases define
stays in the dictionary, as in v3; the system is sealed after POST and
the boot prints PARITY:V4_SYSTEM word_count=N dict_hash=..., as v3 prints
its parity after POST.
Gone: capsules/v4/post79.4th and its blocks 7000 up; the harness words;
(CATCH) and (EMIT-HOOK), with what EMIT and the prompt loop did for them.
The generator runs v3 on the lines as the kernel sends them, without the
capsule's "T| ". One expected result follows from that: >IN.initial
prints 6, not 9.
make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and
riscv64 boot, POST 538 of 538, word_count=411, dict_hash
0x6fb1d09418b189ee on all six: logs/20261007-105118, -105335, -105651.
T{ is unknown at the prompt; RS1 prints 42 42 before and after COLD. A
scratch build with one expectation changed names the case and ends
PARITY:FAIL, POST: FAILED.

mkpost.py writes v4/system/post_cases.c where it wrote the capsule: for
each case its name, its lines, and what it must do -- end in an error, or
leave v3's stack and print v3's output, which is now held in full where
the capsule held its length and a checksum.
The same 538 cases: checked against capsules/v4/post79.4th case by case --
names, lines, stacks, and the length and checksum of each output -- with
no difference. The capsule is still what the boot runs.
